■ STANDARD SPRAG TYPE CAM CLUTCH CONSTRUCTION
The figure shows a representative model from the MZ Series for explaining construction.
Major Component Parts
The major parts of the Cam Clutch are the cams, inner race, outer race, springs and bearings. Each of these
parts play an important role in the function of the Cam Clutch. All parts are made of carefully selected materials,
have undergone appropriate heat treatment, and have passed strict quality control checks.
Part
Cam
Appearance
Function
A number of cams set regularly in between the inner and outer races function
as props or sliders depending on the relative rotating directions of the inner and
outer races. This action causes engagement (clutching) and disengagement
(overrunning) of the clutch inner and outer races.
The cams are the vital component of a Cam Clutch, and they are available in
various models and types to suit a variety of applications.
Inner Race
Outer Race
The inner and outer sliding faces of the races are hardened and precisionground
into a perfectly round cylinder to enable them to withstand the
compressive stress generated during engagement with the cam and sliding
abrasion when overrunning.
Spring
Compressed springs are set at both ends of the cams to ensure that all of the
cams contact the inner and outer races at all times. Thus, the cams are always
ready for immediate engagement. This is extremely important so as to ensure
that the load is spread evenly across all cams when they engage with the inner
and outer races.
Bearing
The bearings maintain concentricity of the inner and outer races and bear the
radial load for the engagement of the cams and the inner and outer races.
Maintaining concentricity is particularly important to ensure that the load is
spread equally and simultaneously over the cams at the time of engagement.
