AI Technical Summary

Technical Problem

The large rolling bearings and planetary gear transmissions in existing wind power equipment are complex in design, heavy in weight, and high in manufacturing cost. They are also prone to damage to parts due to radial loads due to clearance during use, resulting in increased maintenance time and costs.

Method used

A planetary gearbox for wind power equipment is designed. By setting a modified area in the axial contact area of ​​the planetary gear and the planetary shaft, an oil film is formed to bear the load and reduce edge stress concentration. If necessary, an oil storage tank, Hard coating or bronze plating to improve wear resistance and optimize bearing structure to reduce maintenance costs.

Benefits of technology

It effectively reduces edge stress concentration, extends system life, reduces maintenance costs, and improves bearing load-bearing capacity and reliability.

Abstract

A planetary gearbox for a wind power plant has a planet shaft (10), a planet gear (50) and a planet carrier (60), the planet shaft (10) is mounted on the planet carrier (60), the planet gear (50) is mounted on the planet shaft (10), and shaping regions (101, 102, 501, 502) are arranged on the inner circumferential surface of the planet gear (50) and / or the outer circumferential surface of the planet shaft (10) in the axial contact area of the planet gear (50) and the planet shaft (10). The structure of the planetary gearbox can reduce edge stress concentration and prolong the service life of a system.
