■ BR SERIES CONSTRUCTION
NON-CONTACT DESIGN EXTENDS SERVICE LIFE
Greatly Increased Service Life
Made possible by TSUBAKI’s extensive experience in mechanical
power transmission, the cam used in the BR Cam Clutch offers a
unique cross section that provides positive mechanical
engagement only when needed. Otherwise, the Cam Clutch rotates
freely with absolutely no mechanical contact in the clutch
mechanism. The result is a greatly increased service life compared
to conventional types.
Backstop applications with high-speed overrunning
When the Cam Clutch is stationary, the cam locks the
inner and outer races together (figure 1). When the
inner race (load side) overruns at a high speed, the
cam disengages by releasing from the inner race
(figure 2). When the inner race stops, the cam rotates
back into an engaged position. If the inner race tries
to rotate in the reverse direction, the cams then serve
as a prop between the anchored outer race and inner
race to prevent the reverse rotation and provide
backstopping.
High-speed and low-speed-engaged overrunning
When the Cam Clutch is stationary, the cam locks the
inner and outer races together (figure 1). When the
inner race (load side) overruns at a high speed, the
cam disengages by releasing from the inner race
(figure 2). When the high-speed rotation of the inner
race stops and the inner race begins to rotate slowly,
the cam rotates back into an engaged position. Then
when you start to drive the outer race at low speed of
rotation, the cams serve as a prop and drive the inner
race at the same low speed of rotation.
A more economical design.
The open-type BR series features a simple design in
which the Cam Clutch mechanism is incorporated in a
cage between standard dimension inner and outer
bearing races. This allows the Cam Clutch to be easily
and economically integrated into a wide variety of
mechanical systems. A package-type Cam Clutch is
also available to reduce maintenance demands.
