Applications Cam Clutch － 5. Agricultural Machinery （Fertilizer , Pesticide applicator ）
Application
Overrunning
An application to alternately repeat the conditions where the inner and outer races of the cam clutch engage to transmit the torque and where they continue spinning around depending on the difference in the rotation speed or rotation direction. The operation is the same as the free wheeling of a car.

Purpose of Use and Operation Overview
This is a passenger vehicle used to spray agricultural chemicals or fertilizer in fruit farms or other locations. It has a large fan and a chemical/fertilizer tank at the rear. When a chemical/fertilizer is sprayed, the fan is rotated at high speed under fruit trees. The wind generated by the fan turns the chemical/fertilizer into a spray and scatters it around. The inertia of this fan is so large that the fan cannot stop immediately when the engine stops. Consequently, when the work finishes and the engine stops, the fan continues rotation and may damage the shaft. When a cam clutch is attached between the PTO shaft and the fan, the clutch engages and transmits the rotation from the transmission to the fan. When the engine stops, the clutch overruns to break the link between the PTO shaft and fan, providing protection for the PTO shaft and fan.
When Tsubaki's cam clutches are used ･･･
You need to select the cam clutch to be attached to equipment which continues rotation due to an inertia force based on the machine, the fan space, and the transmission torque and rotation speed required for the cam clutch operation.
The ML series (picture on the left) has keyways on both the inner and outer races to allow easy mounting of the clutch to the shaft and of necessary components to the outer race.
Advantage of using the cam clutch
- ・The cam clutch automatically shifts from engagement to overrunning.
- ・No need for an extra switching/control device for switching between engagement and overrunning, allowing a compact design.
