Embodiment approach

[0051] See Figure 8 , the output spiral raceway cylinder 5a is sleeved on the main shaft 1, and forms a helical transmission pair with the main shaft 1, so that the output helical raceway cylinder 5a can slide axially along the main shaft 1, specifically, the helical transmission pair It includes an inner spiral raceway 5a3 distributed on the inner wall of the output spiral raceway barrel 5a along the circumferential direction and an outer spiral raceway 1a distributed on the outer wall of the main shaft 1 along the circumferential direction, and each outer spiral raceway 1a is embedded with A plurality of outwardly protruding balls 27, each ball 27 can roll in the corresponding inner helical raceway 5a3 and outer helical raceway 1a respectively. When the output spiral raceway cylinder 5a rotates relative to the main shaft 1, it can move axially relative to the main shaft 1, so as to compress or release each outer friction plate 2c and inner friction plate 2d, and switch betw...

Abstract

The invention discloses a self-adaptive multi-disc sequenced large torque friction clutch which comprises a friction disc supporting plate, an inner disc spiral raceway sleeve and a plurality of outerfriction discs and inner friction discs alternately arranged between the friction disc supporting plate and the inner disc spiral raceway sleeve, the outer edge of each outer friction disc is in spline fit to the inner wall of an outer disc spline sleeve, the inner edge of each inner friction disc is in spline fit to the outer wall of an output spiral raceway drum, a plurality of inner disc starting retainer rings are mounted on the outer wall of the output spiral raceway drum in a sleeving manner, and each inner disc starting retainer ring is located on the side, close to a friction disc supporting plate, of each inner friction disc. By adopting the structure, the response speed is improved greatly, so that the quantity of the friction discs can be increased greatly, and therefore, the friction clutch can be applied to a large torque scene. It can be ensured that the inner friction discs and the outer friction discs are separated thoroughly and defects of a conventional multi-disc friction clutch are overcome, so that the wear resistance, stability and reliability of the friction clutch are improved greatly.

Description

technical field [0001] The invention relates to the technical field of friction clutch mechanisms, in particular to an adaptive multi-plate sorting high-torque friction clutch. Background technique [0002] The friction clutch uses the mechanical friction between the friction surfaces to transmit the torque from the driving shaft to the driven shaft, and can engage or disengage the main machine and the driven shaft according to the work needs. Friction clutches are mainly disc-type friction clutches including active friction discs and driven friction discs. Their wear resistance is not good. After a long time of use, the sensitivity, stability and reliability will be greatly reduced, and there is a defect of short service life. It cannot be used as a high-torque power transmission device. [0003] Therefore, a multi-plate friction clutch has emerged as the times require. Its core component is composed of multiple friction plates, and the wear is evenly shared by many fricti...
