LT1070/200,LT965/305 ventilation type pneumatic clutch for drilling rig brake
As a kind of friction clutch that uses compressed air as manipulating power source, pneumatic-tyred clutch is widely used in such equipment as oil drilling rig and workover rig, and is also an important part of the drive systems of oil drilling rig and workover rig.
The characteristics of pneumatic-tyred clutch are as follows: large transmitted torque, steady joint, easy to install, vibration absorption, compensation to an extent for the relative radial offset and relative angular offset of drive and driven shafts, small inertia of the driven parts, long service life, compact structure and good sealing.
Furthermore, due to great resistance to deformation of pneumatic tyres, the service life of such tyres will be shortened when the operating temperature is over 60°C, and they tend to become fragile when the temperature is lower than -20°C.
The joint element of a pneumatic clutch is mainly made up of friction disk and friction block and so on.
Pneumatic-tyred clutch can be divided into common type and ventilation type in terms of structure.
Specification:
1. Air tube clutch is a friction clutch that uses compressed air as manipulating power source. Generally, this products used on devices needs large torque transfer and more rapid transmission, such as drilling machinery, watercraft, large mechanical press machine, excavator, ball mill, rubber machinery etc.
2. The air tube clutch has a large transmission torque, combining smooth, easy to install, can make a little compensation of deflection to the angular direction and radial direction of main drive shaft and slave shaft.
Warning :
1.When the rubber air tube is not using.And located indoors or in a dry, cool, ventilated place.
2.The air tube should be stretched out flat and shall not be piled up. It is also not allowed to heap pressure heavy objects on the air tube.
3.The air tube storage areas should be far away from the heat source.
4.The air tube should not be together with acid, alkali, grease or organic solvents.
