Description

Clutch coupling

Technical Field

The invention relates to the technical field of couplings, in particular to a clutch coupling.

Background

Mechanical transmission is widely applied in the field of mechanical engineering, and is mainly divided into: friction transmission, chain transmission, gear transmission, belt transmission, worm and gear transmission, ratchet transmission, crankshaft connecting rod transmission, pneumatic transmission, hydraulic transmission (widely applied in hydraulic planing), universal joint transmission, steel wire rope transmission (widely applied in elevators and cranes), coupling transmission and spline transmission.

When the coupler is adopted for transmission, two ends of the coupler are respectively connected with an output shaft of the prime motor and an input shaft of the working machine. When the power transmission assembly of the working machine fails and cannot rotate continuously, the prime motor can continuously drive the input shaft of the working machine to rotate through the coupler, the input shaft can apply large torque to the power transmission assembly, and the power transmission assembly cannot rotate continuously due to failure, so that other parts can be damaged by continuous operation. However, from the time when the working machine fails to find the fault to the time when the prime mover is turned off, the prime mover will continue to rotate the input shaft of the working machine, thereby applying a large torque to the power transmission assembly and damaging other components.

When the working machine breaks down, when the input shaft of working machine can't rotate, the moment of torsion between jack catch 2 and the chuck 11 of axle sleeve 1 can increase rapidly, the moment of torsion increases and makes the spheroid break away from first spherical groove, can make front stall 4 and spring coil baffle 5 to the direction motion of keeping away from chuck 11, so that the spheroid can break away from first spherical groove, belleville spring receives the extrusion force this moment, the prime mover continues to drive chuck 11 and rotates, the spheroid slides in first spherical groove and second recess 22, chuck 11 takes place to rotate for jack catch 2, jack catch 2 does not take place to rotate because of the trouble of working machine. The prime motor does not drive the working machine to rotate at the moment, and other parts of the working machine cannot be damaged. When the spring ring baffle 5 moves in the direction away from the chuck 11, the displacement monitoring mechanism detects the movement and transmits a signal to the prime mover control system, and the prime mover control system controls the prime mover to stop running.
