Abstract

The invention provides a ball friction type mechanical clutch. The ball friction type mechanical clutch comprises an outer shell, an inner frame assembly, a ball, a reset spring and a shifting fork. The inner frame assembly is composed of an inner frame, a ball baffle and a strong magnet. A slot and a dovetail-shaped slot are formed in the inner frame, wherein the slot is matched with the shifting fork, and the dovetail-shaped slot is used for allowing the ball baffle and the strong magnet to be installed. The ball baffle and the strong magnet are directly embedded into the dovetail-shaped slot in the inner frame through a dovetail-shaped base, the ball is arranged on the strong magnet and limited by the ball baffle, the reset spring is installed between the shifting fork and the inner frame, the shifting fork is inserted into the slot of the inner frame, and the inner frame assembly and the ball are jointly arranged in the outer shell. The ball friction type mechanical clutch is large in transmission torque, capable of resisting impact, and suitable for working occasions where frequent temporary joint exists.

Description

technical field [0001] The invention relates to a clutch, in particular to a friction mechanical clutch. Background technique [0002] Due to the need for starting and stopping of mechanical equipment, clutches are commonly used in transmission systems. The clutch realizes the equipment stop, start and gear shift functions by cutting off and combining the power system and the transmission system. At present, the commonly used clutches mainly include pneumatic, mechanical, hydraulic, and electromagnetic clutches. Among them, mechanical clutches mainly include meshing and friction clutches, and commonly used friction clutches mainly include disc clutches and cone clutches. The friction clutch engages smoothly, even at high speed, the clutch is also very stable, but the transmission torque is small, and the working plane slips when overloaded, so it has the function of overload protection. In the process of clutching and slipping, the driving shaft and the driven shaft cannot...
