Problems solved by technology

[0002] In the brake caliper structure of the main shaft system of the traditional wind turbine, there is no special brake block return device, and the return of the brake block returns the brake block through the rotation and axial movement of the brake disc after pressure relief. Or by setting a special piston return seal ring structure in the brake caliper body, the structure is complex, the brake pads and brake discs are prone to dragging, the life of the brake pads and brake discs is low, and the system maintenance cost is too high

Abstract

The invention discloses a brake caliper assembly of a normally open type wind driven generator main shaft system, comprising a first half part, a second half part and an inner brake block resetting mechanism which are correspondingly arranged, wherein, the inner brake block resetting mechanism comprises a return spring installation rod and an inner brake block return spring sheathed on the excircle of the return spring installation rod; the return spring installation rod and a piston are parallel and pass through the first part in the mode of reciprocating sliding lengthways; one end of the return spring installation rod is fixedly connected with the inner brake block lengthways; one end of the inner brake block return spring outwards supports the return spring installation rod, and the other end inwards supports the first half part; when the brake assembly enters a non-working state (the hydraulic cylinder releases pressure), the brake block can effectively and quickly separate from the brake disc by the brake block resetting mechanism, which reduces abnormal abrasion between the brake block and the brake disc so as to improve the service life of the brake block and the brake discand reduce maintenance cost.

Description

technical field [0001] The invention relates to a brake, in particular to a brake caliper assembly of a normally open wind power generator main shaft system. Background technique [0002] In the brake caliper structure of the main shaft system of the traditional wind turbine, there is no special brake block return device, and the return of the brake block returns the brake block through the rotation and axial movement of the brake disc after pressure relief. Or by setting a special piston return seal ring structure in the brake caliper body, the structure is complex, the brake pads and brake discs are prone to dragging, the life of the brake pads and brake discs is low, and the system maintenance cost is too high . Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a brake caliper assembly for the main shaft system of a normally open wind power generator. On the basis of the brake caliper of the existing main shaft syste...
