The reading of the ambient temperature value and the reading of the working temperature value should be carried out simultaneously. Thermometer division value is 0. The height of the measuring point of the thermometer from the ground is equal to the height of the axis of the reducer. Measurement of working temperature. 2. 2. Measurement of ambient temperature

At this stage, my country's bearing manufacturing industry has established a bearing industry system with a reasonable layout, scientific research and logistics support. After five five-year development plans, my country's bearing industry has seized the opportunity and achieved tremendous progress.. As the country further increases the intensity of infrastructure construction, my country's reducer industry has developed rapidly.

Bearing industry, as an important sub-industry in my country's basic machinery industry, started with the Republic and has a long history. Especially since the mid-1960s, my country focused on the construction of a batch of bearing factories in the third-tier regions of the southwest, northwest and central south, which improved the layout of the bearing industry. Therefore, the bearings are indispensable parts in the reducer. With the gradual improvement of the industrial chain of the reducer industry, the relationship between the industries is getting deeper and deeper.

As a power transmission mechanism, the reducer uses a gear speed converter to reduce the number of revolutions of the power source to the required number of revolutions. From the perspective of production scale, my country's bearing industry ranks third in the world due to its relatively large production volume. With the breaking of the old economic system and the gradual formation of the market economic system, the production capacity of my country's bearing industry has gradually improved, and the technical level has been significantly improved. Planetary gear reducer The bearing industry has established a relatively complete industrial system.

Only by grasping the development of the overall industry can we gain a foothold in the fierce market competition. The development of the reducer industry is inseparable from the development of the bearing industry. The gears of the reducer will produce friction during work, and bearings are needed to fix and reduce friction. In the 1970s, the bearing industry and automobile manufacturers developed at the same time, and the automobile bearing production base gradually formed, ushering in the second peak of the development of China's bearing industry.

The reform and opening up in 1978 opened a new chapter in Chinese history and set off the third wave of the development of the bearing industry. The development of the bearing industry also always affects the development of the reducer industry. Under the guidance of Deng Xiaoping Theory, my country's bearing industry has continuously carried out system reforms, introduced advanced foreign technologies and used them for our purposes, actively expanded opening up, liberated productivity, and significantly enhanced comprehensive technical strength, and gradually improved its inteational status

Major national projects such as the Three Gorges Project, Xichang Satellite Launch Center, Beijing Olympic Stadium and Shanghai World Expo Park have become the first choice of the global top 500 suppliers, and have been exported to dozens of developed countries such as the United States, Germany, Japan, South Korea, Singapore, and Hong Kong. Academician Wu Hongxin of the Chinese Academy of Sciences, who is the chairman of the Equipment Appraisal Committee, pointed out at the scene that this innovative achievement embodies the principle of digestion, absorption and re-innovation.

Steel cord equipment. Countries and regions. Significant historical change.The deep integration of the two industrializations of the reducer industry has accelerated the pace of domestically produced reducers entering the inteational high-end field. Through the development of embedded technology, products are given high-performance control, intelligent operation and remote monitoring systems, and promote products to integrate into the digital and networked inteational high-end industrial chain.

In 2010, approved by the National Nuclear Power Equipment System, high-power vertical nuclear power gearboxes were put Wholesale Parallel Shaft Gearboxes Suppliers into nuclear power engineering assembly bases. The development of this high-tech equipment will enable my country’s complete set of metal wire equipment to be imported to export.

Let domestic high-precision transmission equipment replace imports, and then squeeze into the inteational high-end market application field, which is the foothold of the scientific and technological innovation concept and the deep integration of the two industrializations to develop innovative products. The localization of nuclear power gearboxes is a major breakthrough in the deep integration of the two. The products are widely used in South-to-North Water Diversion, West-East Gas Transmission, etc. 

Question---When buying lubricant products, ask more questions. Cut ---Most regular lubricant products have relevant anti-counterfeiting measures.. Information on rights protection incidents and investigations of counterfeit lubricants has also been reported frequently in recent years.

If the car owner uses inferior engine oil, it will not only affect the life of the engine, but also may 'broken down' at any time and cause huge losses. Smell---I always remind myself that cheap goods are not good. For example, Kunlun Lubricating Oil has four high-tech anti-counterfeiting technologies including random image anti-counterfeiting, two-dimensional code anti-counterfeiting, mirror image discoloration anti-counterfeiting, and special ink anti-counterfeiting to prevent product counterfeiting.

How to choose reducer lubricants and how to avoid buying fake lubricants has become a new problem for drivers and purchasers. To this end, the person in charge of a well-known domestic lubricant Wholesale Cylindrical Gear Reducer Company brand, Kunlun Lubricant, who has been in charge of anti-counterfeiting for a long time, said, 'Consumers can easily distinguish between genuine and fake lubricants as long as they have a grasp of 'seeing, hearing, and asking'. Hope --- is to observe the product packaging.

With the growth of China's automobile production and sales, the lubricating oil market has shown huge business opportunities, and some unscrupulous dealers and manufacturers have also started the idea of ​​fake lubricating oil

Stainless steel pipe fittings are divided into threaded pipe fittings and welded pipe fittings. Defects such as pores, cracks, etc. The pipe cutting Cycloidal Gear Reducer Manufacturers of stainless steel pipe fittings cannot be cut with ordinary grinding wheels, and special grinding wheels or plasma should be used for cutting.

When the material is hoisted, it should not be in direct contact with other metals, and should be padded with non-metallic materials such as wooden boards or rubber sheets. It is forbidden to arc or start arc on the surface of the base metal of pipes and fittings. 

According to the material, they can be divided into 304, 321, 310 and so on. After welding, the pipe fittings should be pickled and passivated.The arc starting of the multi-pass and multi-layer welding of stainless steel pipe fittings adopts the reflow method, and the arc crater should be filled in when the arc is closed. Next, Tenghai will introduce you to the related issues of stainless steel pipe processing and transportation.

The production standards are divided into inteational standards, American standards, and German standards.  During tack welding, the inside of the weld should be filled with argon for protection. found in the arcing or arc starting should be cleaned up. Pipe fittings made of stainless steel, including stainless steel elbows, stainless steel tees, stainless steel crosses, stainless steel reducers, stainless steel caps, etc.

The concentricity of the calibrated mounting shaft should not exceed the allowable range of the coupling.The shaft diameters of the output shaft and the input shaft are matched with GB1568-79. When installing the reducer on the foundation, the elevation of the installation center line of the reducer, levelness and related dimensions of the connected parts should be calibrated.

Cycloidal pinwheel reducer installation:  The configuration of the cushion block should avoid causing deformation of the machine body, and should be arranged symmetrically on both sides of the foundation bolts, and the mutual distance can be sufficient to allow the water slurry Belt Conveyor Pulleys to circulate freely during irrigation. The eyebolts on the reducer are only for lifting the reducer.

When installing couplings, belt pulleys, sprocket and other coupling parts on the output shaft of the cycloid reducer, direct hammering is not allowed, because the output shaft structure of the reducer cannot withstand axial hammering Force, screw the screw into the screw hole at the shaft end and press into the coupling.

The height of the spacers does not exceed three blocks, and it can also be carried out with a contract iron, but the reducer should be replaced with flat spacers after calibration. The irrigation of cement slurry should be dense, without bubbles, voids and other defects. When the reducer is calibrated, it can be carried out with steel spacers or cast iron spacers.

If multi-stage transmission is used, the reduction ratio is greater. Cycloid needle teeth have a large number of meshing teeth, a large overlap coefficient and a mechanism of mechanical balance, so that vibration and noise are limited to the minimum possible level.Reasonable design, convenient maintenance, easy to disassemble and install, need fewer parts and simple lubrication, so that the cycloid reducer deeply gains the trust of users. Compared with other reducers of the Wholesale Bevel Helical Gearboxes Manufacturers same power, the weight and volume are more than 1/3 smaller.. Therefore, the first-level deceleration efficiency reaches 94%. The reduction ratio of the first-stage transmission of the cycloidal pinwheel reducer is 9~87, and the reduction ratio of the two-stage transmission is 121~5133.　　

Compact structure and small volume Due to the planetary transmission principle, the input shaft and output shaft are on the same axis, so that the size of the model can be as small as possible. The wear is very small, so it is durable. Because of the planetary transmission, the input shaft and output shaft are on the same axis to obtain the smallest possible size. The multi-stage combination can reach tens of thousands, and the pin-tooth meshing system is sleeve-type rolling friction, and the meshing surface has no relative sliding　

Reliable use and long life. Because the main parts are made of bearing steel quenching treatment (HRC58-62), and then finely ground, and the cycloidal tooth and the needle gear sleeve are meshed and transmitted to the needle teeth to form rolling friction.There are many pairs of teeth contacting at the same time during operation, the degree of coincidence is large, the operation is stable, the overload capacity is strong, the vibration and noise are low, and the noise of models of various specifications is low.

Cycloidal pinwheel reducers are widely used in petroleum, environmental protection, chemical, cement, transportation, textile, pharmaceutical, food, printing, lifting, mining, metallurgy, construction, power generation and other industries. Because the main parts are made of bearing steel, they are quenched (HRC58-62) to obtain high strength, and part of the transmission contact uses rolling friction, so it is durable and has a long life. The friction coefficient is small, so that there is no relative sliding in the meshing area. Let me introduce its features to you! Cycloidal pinwheel reducer features . high-speed ratio and high-efficiency single-stage transmission, it can reach a reduction ratio of 1:87, and the efficiency is above 90%.

The speed regulation and control of electric motors are one of the basic technologies for various types of industrial and agricultural machinery and office and civilian electrical equipment. . With the Wholesale Explosion-proof Gear motors Manufacturers amazing development of power electronic technology and microelectronics technology, the AC speed regulation method of 'special frequency induction motor + frequency converter' is being used for its excellent performance and economy, leading a field to replace the traditional in the field of speed regulation.

The gospel it brings to all walks of life lies in: greatly improving the degree of mechanical automation and production efficiency, saving energy, improving product qualification rate and product quality, correspondingly increasing power system capacity, miniaturizing equipment, and increasing comfort.

The renewal of the speed regulation method.. The motor used for this type of control is called a variable frequency motor.The frequency conversion technology actually uses the principle of motor control to control the motor through the so-called frequency converter.

The fast speed replaces the traditional mechanical speed regulation and DC speed regulation scheme. Due to the particularity of the variable frequency power supply, as well as the system's requirements for high-speed or low-speed operation, and rotational speed dynamic response, strict requirements are put forward on the motor as the main body of power, which brings new topics in electromagnetic, structure, and insulation to the motor
