The Coupling Has Impact Resistance
Couplings are also called to find concentric. Pump, the motor is installed, the last job is to pump and motor to find concentric, that is, Scrow-on Couplings the axis of the pump and the prime mover in the same straight line, so that in the operation will not cause vibration.
Couplings mainly through the preload to achieve no back to the transmission torque, shaft connection without air back, good flexibility and impact resistance, Scrow-on Couplings allowing the direction of the offset, even at high speed, the movement is smooth, can withstand large Workload.
Couplings as a transmission of the drum-shaped tooth coupling, is developed by the ordinary straight coupling coupling evolved, drum-shaped tooth coupling in many foreign advanced industrial countries have a variety of standards and products , Composed of two drum-shaped outer gear and a pair of straight teeth gear ring gear and other parts.
The relative transmission of the two drive shafts is compensated by the rotation of the inner and outer gears (called angular displacement) of the gears of the outer teeth of the drum teeth. The greater the drum length, the greater the angular displacement, up to 6 °, the general use of recommended 1 ° ~ 1.5 °, while the old gear coupling only allows 0.5 °; from the bending strength and load capacity, Under the same working conditions, the transmission torque of the drum-shaped gear coupling can be increased by 15 to 20%.
Tooth length direction of the drum, so that the teeth on the contact is better, so the coupling has a large transmission capacity, angular displacement, smooth transmission, high efficiency, long life and other advantages. So gradually replace the straight teeth coupling, Scrow-on Couplings and widely used in metallurgical machinery, heavy, mining machinery, lifting, transport machinery and other transmission.
Coupling bearing the impact of good performance, but the tooth surface contact stress and tooth root bending fatigue strength requirements, if we take a special structure, special materials, Scrow-on Couplings special technology, then the coupling will be able to meet the requirements of large diameter pipe mill.
Diaphragm coupling for high temperature, high speed, corrosive media conditions of the environment of the shaft drive, such as pumps (especially high power, chemical pumps), fans, compressors, hydraulic machinery, petroleum machinery, printing machinery, textile machinery , Scrow-on Couplings High-speed power transmission system, steam turbine, piston-type power transmission system, crawler-type vehicles, and generators high-speed, high-power mechanical transmission system, the economic balance After the application of high-speed transmission shaft has been more common.
