AI Technical Summary

Technical Problem

In the yaw brake system of existing wind turbine units, it is difficult to clean the brake caliper oil leakage and wear of the brake chip powder in time, resulting in degradation of braking performance and wear of the brake disc, affecting the service life.

Method used

A powder guide groove is opened on the side of the friction plate near the brake disc, combining the push rod and intermittent transmission mechanism to slow down heat attenuation through air circulation, and quickly discharge wear powder and oil leakage. The distance measuring module is used to monitor wear and realize automatic cleaning.

Benefits of technology

It effectively improves the braking performance of the brake caliper, reduces the wear of the brake disc, extends the service life of the brake disc, and reduces the energy consumption and structural complexity of the cleaning device.

Abstract

The invention relates to the technical field of yaw braking systems, in particular to a cleaning device for a yaw braking system of a wind generating set. A powder guide groove is formed in a friction plate of a brake caliper, and the extension direction of the powder guide groove is the braking direction of the brake caliper; the brake caliper arrangement structure further comprises a push rod and an intermittent transmission mechanism in transmission connection with the push rod, the first end of the push rod is matched with the powder guide groove, the intermittent transmission mechanism is connected to the axial position of the bottom plate, and the push rod is configured to be driven by the intermittent transmission mechanism, switched to the next brake caliper arrangement gap and extend into the powder guide groove every time the bottom plate rotates by the # imgabs0 ring. Heat attenuation of the friction plate can be slowed down through the powder guide grooves, generated powder and leaked oil can be discharged, the oil discharging effect is improved, an oil film can be prevented from being formed on the surface of a brake disc, and the braking performance of the brake caliper is effectively improved; through cooperation of the push rod and the intermittent transmission mechanism, motor driving is not needed, unblocking of the powder guide grooves in the brake calipers can be achieved only through the push rod and the intermittent transmission mechanism, and energy consumption of the cleaning device is reduced.
