Comparison between clutch and shaft coupling?
|
Clutch |
Coupling |
|
Clutch is a device
that provides a temporary connection between the driver and driven shaft. |
Coupling makes the
permanent and semi-permanent connection between two shaft ends. |
|
Used where driven
shaft/ driven machine required to be in intermittent service. |
Coupling used
where driven shaft required to be in continuous service. |
|
Clutch allow
disconnection during the operation. Provide a mechanism for rapid engagement and
disengagement during the operation at the operator will. |
It does not allow
disconnection of the shaft during the normal operation (Torque limiting
coupling allow slipping when torque limit is exceeded). Connection is in permanent
nature, so there is no mechanism for quick connection and disconnection. |
|
Clutch transmit
power between two colinear shafts. |
Coupling used to transmit
power between colinear as well as non-collinear shafts. |
|
The driven shaft can
run at variable speed. |
In coupling, the driven
shaft run at the same speed as the driveshaft. |
|
Example: Disc
clutch, Cone clutch, Centrifugal clutch, Electromagnetic clutch |
Example: Universal coupling, Oldham coupling |
