HBDC-100 air multi-disc friction plates clutch for engineering vehicle

HBDC-100 air multi-disc friction plates clutch for engineering vehicle

Pneumatic multi-disc friction cluth HBDC is a special industrial clutch. Its friction plates' material is steel and copper-based steel, there are some groups of them in each clutch. Because of this material, so it will not slippage and can be used in dry and wet working situation. Clutch is made of groups friction plates, so it can transmit high torque then used in hard working environment.

HBDC pneumatic clutch is based on BDC air shaft clutch, so outside of HBDC is nearly the same as BDC clutch. The only difference is its flange plate higher than BDC clutch, it is convenient for installation. Fixing this flange plate on the worktable via four screw nuts is enough. It is with compact size while delivery high torque for modern machines.

HBDC pneumatic clutch is a special pneumatic shaft friction clutch. Its friction plate is not non-asbestos material, HBDC clutch's friction plate are made of group steel plates and copper-based plates, it is strong and durable. The HBDC-50 and HBDC-100 can transmit high torque from 500N.m to 1000N.m.

This HBDC multi-disc air clutch is so special and outstanding, how it is working? 

After supplying air pressure, piston pushes driving plate to slide along the direction of the axis, group steel discs compressed group copper-based friction plates to come into an integrated structure, clutch linked. Group steel discs and group copper-based friction plates are separated by separate springs after exhausting air pressure, clutch released.

There are two models of it: HBDC-50 and HBDC-100, they can delivery high torque with compact size. Following is the detail technical data of it for yourr reference:

From above two tables, we can see that this HBDC pneumatic clutch is also an air shaft clutch, its bore diameter is 35mm and 50mm in separately. Although its dimension is small, it can delivery high torque durable usage. 

This HBDC air clutch is friction type clutch, so it is suitable for high speed connecting and rotating. Its max linking speed is 2500r/min, fastest rotating speed can be reached to 2500r/min. 

HBDC is a hard clutch, the installation should be careful. Following is some of installation instruction of this clutch for your reference:

1. Connect rotation

Air cylinder and piston will be caused connect rotation by bearing, it can be use 3 pieces of stop grooves in 120°angle or auxiliary stop groove screw holes to fix or stop. Be careful, when they are stopped, cylinder shouldn’t be incline because of interference power, or it will influence clutch normal working.

2. Precaution when installation clutch onto shaft

It is better to use professional tool to inflate hollow shaft tube when install clutch onto shaft, don't hit cylinder or other easy wearing parts.

3. Belt pulley and gear installation

When install belt pulley or gear onto clutch driving cover, try to make sure radial force center of belt pulley or gear is align with two unit of bearings loading center of driving cover. Excessive incline will influence clutch service life.

4. Bearing lubrication

The trust ball bearing should be lubricated periodically. The period is between 1 to 6 months according to using occasion. Because the other bearings are sealed, there is no need to supply.

5. Avoid high load working

It is better to use double or triple safety factors when choose model, overload usage will reduce clutch service life. When usage frequency exceed 2-3 times per minute, we suggest use larger safety factor, the allowable maximum usage frequency is 6 times per minute.

6. Usage environment

Avoid used in oil environment. In case of dust, sand, gravel and other impurities enter into the friction plate work area, we suggest add a protect cover on clutch.

This BDC series air multiple friction plates clutch is widely applied in industry automation, packing and printing machinery, engineering sanitation vehicle, water pump fan and etc. It is just a connector, to transmit power motor from driving part to driven part easily.
