Abstract
A decoupling device for gear motors used in cargo conveyor belt systems in which a coupler member is free to move axially on the output shaft of the gear motor to cooperate with the final gear of the gear train in the motor housing. A spring member maintains the coupler in engagement with the final gear via the corresponding jaw structures. Disengagement of the respective jaw structures is accomplished by axially moving the coupler member along the output shaft by means of a self-securing pivotally mounted yoke which engages the coupler for transmitting axial motion thereto. The yoke is pivoted by means of a cam follower device mounted for pivotal movement exteriorly of the gear housing to thereby rotate to one of two positions, thus connecting or disconnecting the aforementioned respective jaw structures on the output shaft.
Claims6
A decoupling device for a gear motor comprising,
- a housing,
- an output shaft extending throught said housing,
- a drive gear rotatably mounted on said output shaft,
- a coupler member slidably mounted on said output shaft,
- an overcenter spring mounted on said output shaft adjacent said coupler member,
- a yoke member threadably mounted on an axially rotatable shaft means and defining a threaded joint therebetween, said yoke member being connected to said coupler member for translating movement thereto along said output shaft for coupling said drive gear therewith in one end-stop position and decoupling said drive gear therefrom in another end-stop position,
- a cam-follower fixedly supported on one end of said rotatable shaft means,
- a cam pivotally supported adjacent said cam-follower for angularly displacing said cam-follower to thereby rotate said rotatable shaft means and said yoke member thereon to one of said end-stop positions, wherein rotation of said rotatable shaft towards one of said end-stop positions serves to tighten said threaded joint, and
- said cam-follower having spaced apart stop means for restricting the angular movement of said cam between said end-stop positions.
A decoupling device for a gear motor comprising,
- a housing,
- an output shaft extending through said housing,
- a drive gear rotatably mounted on said output shaft,
- a coupler member slidably mounted on said output shaft,
- an overcenter spring mounted on said output shaft adjacent said coupler member,
- a yoke member removably mounted on an axially rotatable shaft and being connected to said coupler member for translating movement thereto along said output shaft for coupling said drive gear therewith in one end-stop position and decoupling said drive gear therefrom in another end-stop position,
- a cam-follower fixedly supported on on end of said rotatable shaft
- said one end of said rotatable shaft extending through said housing, whereby said cam-follower is supported adjacent an outside wall of said housing,
- a cam pivotally supported adjacent said cam-follower for angularly displacing said cam-follower to thereby rotate said rotatable shaft and said yoke member thereon to one of said end-stop positions, and
- said cam-follower having spaced apart stop means for restricting the angular movement of said cam between said end-stop positions.
