Friction type torque limiting clutch

Abstract

The invention discloses a friction type torque limiting clutch which comprises a driven shaft interface, a shell, a driving shaft interface and a friction sheet combination, wherein the friction sheet combination is composed of an outer friction sheet and an inner friction sheet; the driven shaft interface is connected at the front end of the shell; the driven shaft interface is arranged inside the shell; the rear end of the shell is connected with a spring base which is sleeved on the driving shaft interface; spring holes are uniformly distributed on the spring base along the circumference; a spiral spring and a cushion block are arranged in each spring hole; one end of the spiral spring props against the cushion block; the other end of the spiral spring stretches outside the spring hole to prop against a pressing ring; a screw hole corresponding to each spring hole is arranged on the rear side plane of the spring base; an adjusting screw is arranged in the screw hole; the adjusting screw props against the cushion block; a locking nut is arranged on the adjusting screw; the front end of the driving shaft interface is connected with an end shaft; the front end of the end shaft is inserted into the hole of the driven shaft interface; and the end shaft is in clearance fit with the hole of the driven shaft interface. The adjusting screw can be adjusted by only using an ordinary small torque winch, so that the on-line adjustment is carried out on a production line conveniently.

Description

technical field [0001] The present invention relates to torque limiting clutches. Background technique [0002] A torque-limiting clutch is a clutch that ensures that the transmitted torque or speed does not exceed a certain limit value. A suitable torque-limiting clutch needs to be installed in large-scale mechanical equipment to prevent damage to the motor and transmission system due to drastic load changes. There are many types of torque-limiting clutches, and friction-type torque-limiting clutches are one of them. The Chinese patent number is ZL200820098498. The utility model manual of X discloses a dry friction safety clutch, which includes a driving shaft, a transition shaft and a driven shaft. The wheel is equipped with an inner friction plate; one end of the transition shaft is equipped with a bearing, and the other end is fixedly connected with the sleeve on the driven shaft; the sleeve is equipped with an outer friction plate, a support plate and a spring seat, a...

Problems solved by technology

The above-mentioned multi-friction plate safety clutch is prone to eccentric wear of the friction plates due to the use of disc springs, and the adjustment accuracy is relatively low
