Pneumatic Clutches: Uses and Capabilities

金莎全部网址are very powerful and an excellent fit for the large industrial machines your company depends on for your toughest job-site challenges, including auto cranes and other construction vehicles.

They offer a simple method for adjusting torque by providing excellent torque control, which is necessary for more heavy-duty vehicles and machines. While金莎全部网址usually have torque limiters that vary around 10 percent, pneumatic or空气离合金莎网址器typically limit torque variance to less than 5 percent — a significant difference. Pneumatic clutches are normally able to provide more speed and flexibility than mechanical clutches, for even larger machines.

To summarize: More torque. More power. More speed and flexibility. Sound good?

Let’s take a look at how they work:


Pneumatics is the branch of technology that concerns the way gases can be used for mechanical purposes. In most pneumatic machinery, the gas used is the simplest of gases — clean air. In other words, pneumatics usually describes the use of air to move things. Unlike mechanical clutches (where solid moving parts do all the work), pneumatic clutches employ tightly compressed air to transfer energy from one moving part of a machine to another.

For example — you know those air tubes at the bank drive-through? Those use pneumatics in a similar, albeit much simpler, way. At the bank drive-through, when you put a check into the container and send it off, compressed air quickly shoots through the tube and pushes the container all the way to the bank teller.



VC-Style and CB-Style Air Clutches

At KL Clutch, we’re proud to provide both VC-style and CB-style金莎全部网址— the sort rugged enough for peak, reliable performance out in the oilfields, and flexible enough to be provide pneumatic clutch solutions across a variety of other industrial applications.

Both are constricting-type clutches featuringOil State’s ELASTA-FLEXdrum clutch elements—a flexible, fabric-reinforced inflatable elastomeric tube that expands radially inward—designed for severe, demanding clutch applications. When the tube constricts, it pushes the friction shoes against an outer cylindrical drum surface, which makes it easy to accurately determine and control element torque capacity.

Let’s take a look at the unique capabilities of each:

VC型气动离合器金莎网址: Better heat dissipation. Higher torque capabilities. Increased longevity.

VC elements were principally designed for severe, high-torque, high-thermal-capacity clutching in heavy machinery with high starting loads. In other words: toughness, toughness, toughness.

由design, torque gets transmitted via torque bars from the side plates to the friction shoes. They work well for a few reasons: A well-ventilated construction improves heat dissipation from the friction shoes and cooling airflow. And the clutches boast high torque ratings, which makes it easy to use smaller diameter units (better for lowering contact velocity on high-speed applications). Because of what’s required of them, VC-style air clutches are in are in many ways considered to be the most trusty, tough styles of drum clutches.


CB型气动离合器金莎网址: torsional resilience and flexibility

CB-style air clutches, meanwhile, are most noted for their flexibility. Designed for power transmission in oilfield machinery, the CB elements work best in high-speed, medium torque applications—especially those where high heat generation (as seen in VC applications) is less of a problem. CB torque also gets transmitted through a sort of flexible neoprene side wall and cord actuating tube, which lets minor, naturally occurring shaft misalignment happen without causing larger problems. The neoprene tube automatically tightens up when friction surfaces wear, providing constant compensation.

Out in the oilfield, the CB-types fit a more broad array of applications than VC types, including engine, slush pump, and PTO applications.
