Problems solved by technology

[0002] The clutch is the "switch" of power transmission. It is a transmission mechanism that can transmit power and cut off power; the clutch connects two shafts so that the two shafts are locked together, rotate at the same speed, or separate; There are many types of clutches in the past, including mechanical, pneumatic, hydraulic, electromagnetic, centrifugal, etc., but the mechanical type is most widely used in the machinery industry; there are many kinds of mechanical clutches, such as gear Type clutches, rotary key clutches, conical friction clutches, etc., each have their own advantages, but there are defects such as poor workmanship, high noise, and short life; torsion spring friction clutches are not only simple in structure, but also small in size, reliable in operation, and long in service life.

Abstract

The invention discloses a torsional spring friction clutch. The friction clutch comprises a driven shaft, a case, a friction drum, a key, a torsional spring, a lever, a pressurizing disc, a driving shaft and the like. During engagement, the pressurizing disc moves leftwards along the driving shaft, the lever rotates around a hinge pin, a connecting rod moves downwards, the torsional spring is compressed layer by layer, the whole torsional spring is contracted along with the contraction of the first circle of the torsional spring, the inner diameter is reduced, and the drum is tightly hooped, so that the driven shaft is driven to rotate together; during disengagement, the torsional spring bounces to be separated from the drum. The clutch is simple in structure, small in outline dimension, reliable in working and long in service life.
