BTC-20 pneumatic tooth clutch used in mechanical arm as a brake

BTC-20 pneumatic tooth clutch used in mechanical arm as a brake

As usually, BTC pneumatic tooth clutch is used to connecting power. But in some special case, it is applied as a brake, such as mechannical arm, manipulator and etc. In this situation, BTC is reverse installation to be a brake for joint part locking.

When it is used as a brake, it is normal releasing. That is to say, when there is no air input, this BTC brake is released; after inputting air source, brake linked for locking. It is usually used for joint braking.

BTC clutch is very special, it can be used as a clutch and brake as needed. Handong company is a professional manufacturer with full experience for clutch and brake make, each product made with superior quality and competitive price.

Compared with electromagnetic clutch, this pneumatic tooth clutch will not reduce torque and produce spark for over heat,to ensure heavy workload finished. With torque control range, it is most suitable work as a tension controller. Controlled by air pressure, soft start and stop. Through clutch opetation, adjustment, stable engagement, so as to make full braking performance. Simple structure, easy maintenance and long service life. 

There are some models of this pneumatic tooth clutch. Following are the structure and technical data of this pneumatic tooth clutch for joint:

This air driven tooth clutch is a type of air shaft clutch, different model, its bore diameter is different, too. From above technical data, we can see that BTC pneumatic clutch bore diameter is 20-120mm. It is with compact size, while transmit high torque, its max torque can be reached to 16000N.m. 

BTC clutch is tooth and tooth connecting, so it is only suitable for slow speed or standstill linking, its connecting speed is 20-100r/min. After connecting, tooth clutch can be rotated fastly, max speed reached to 2300r/min. As we know, BTC clutch is tooth and tooth connect, the model larger, its tooth quantity is more, so its torque is higher, too. For example, BTC-20 pneumatic clutch tooth quantity is 180 pieces, max torque is 200N.m; BTC-120 clutch tooth quantity is 270 pieces, its max torque is 1200N.m.

Following is the usage case of BTC pneumatic tooth clutch worked as a brake in mechannical arm for locking. It is connect and separated fastly after inputting and outputting air source.
