CAM CLUTCH

A-2-2. Application for the purpose of braking the
driven side (see the figure below)
The example here shows an application in which the
hose drum of a pipe flusher is being driven. When the
hydraulic motor is rotated in reverse in the
counterclockwise direction, the Cam Clutch inner race
rotates in reverse, and the Cam Clutch overruns. The
flushing pump is driven in this state. The flushing water
passes through the hose and gushes out of the nozzle
toward the back. The force of this water jet starts the
nozzle running and pulls and unwinds the hose. At the
same time, the hose drum starts reverse rotation in the
same counterclockwise direction, and increases its
speed of rotation until it reaches the overrunning speed
of the inner race. At this point, the Cam Clutch
engages, and the hydraulic motor works as a brake to
stop the acceleration of the drum. Therefore, the
running speed of the water jet nozzle is kept constant
thereafter. When the hydraulic motor is rotated normally
in the clockwise direction, the Cam Clutch engages to
wind the unwound hose onto the drum.
A-2-3. Application for the purpose of selectively
driving either one of two driven units by
normal or reverse rotation of the drive input
(see the figure below)
When the motor is rotating normally (in the
counterclockwise direction), Cam Clutch A engages to
drive unit A, and Cam Clutch B overruns. Conversely,
when the motor is rotated in reverse (in the clockwise
direction), Cam Clutch B engages to drive driven unit
B. In this application, the two driven units must work
independently.

• Grease is sealed in, so lubrication maintenance is not required.
• Same dimensions as the #62 type bearing.
• Integrated Cam Clutch and bearing.
• Sleeve-type outer race enables mounting of sprocket or gear with small outer diameter.
• Use of oil-impregnated alloy bearings makes oiling the bearing section unnecessary.
• Since this series is mounted directly to the shaft, it is possible to use a large diameter shaft.
• Compact designs are possible.
• Grease is sealed in, so lubrication maintenance is not required.
• For light loads and low-speed drive.
• Compact and transmits high torque.
• Excellent wear resistance when overrunning.
• MG type reinforced spring type. Excellent response to load change.
• Outside dimensions ara the same as #62 type bering.
Compact designs are possible.
• Outside dimensions ara the same as #63 type bering.
When the engaged time is long
and load change is considerable,
choose the SS (reinforced spring)
specification. In this specification,
the response of cam following
load changes during Cam Clutch
engagement is enhanced. Use the
Cam Clutch at an overrunning
speed of 50 r/min or lower.
