China Parallel Gearbox

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 caot 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 coected 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 caot 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.u3000u3000

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 slidingu3000

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.ufeff

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.ufeffThe 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
