Wind-powered turntable bearing combination property bench

Abstract

The invention relates to a comprehensive performance experiment table for wind power turntable bearings, which consists of a bottom plate (1), a lower adapter flange cylinder (2), a power assembly (3), the wind power turntable bearings (4), an upper adapter flange cylinder (6) and a loading cover (10), wherein at least one pair of wind power turntable bearings are connected to the lower adaptor flange cylinder (2) and are two wind power turntable bearings which have the same specification and adopt the mounting means of 'back to back'; a pinion (25) is arranged on the power assembly (3) and meshed with gear teeth of an inner ring or an outer ring of one wind power turntable bearing or gear teeth of inner rings or outer rings of two wind power turntable bearings; the upper adapter flange cylinder (6) is detachably connected to upper parts of the wind power turntable bearings (4); and the loading cover (10) is detachably connected to the upper part of the upper adapter flange cylinder (2). The comprehensive performance experiment table for the wind power turntable bearings has a compact structure, is convenient to assemble, can realize modularized adjustment according to different wind power turntable bearings, and can simultaneously realize loading of the axial force, the radial force and the capsizing moment.

Description

technical field [0001] The invention relates to a large-scale bearing test bench, in particular to a wind power turntable bearing comprehensive performance test bench. Background technique [0002] The wind power slewing bearing is a huge inner ring or outer ring with transmission teeth. It is mainly composed of inner ring, outer ring, rolling elements, spacer blocks, etc. It is a key component of wind turbines. Compared with ordinary bearings, the loading state of wind power slewing bearings is more complicated, and generally bears the axial force F a , radial force F r , overturning moment M, and these loads are in an alternating state, resulting in fatigue failure of the wind turbine rotating disc bearing. In recent years, the installed capacity of wind power generators has grown rapidly, which has driven the development of wind power pitch and yaw slewing bearing industries. Many domestic manufacturers have invested in the production of pitch and yaw slewing bearings. ...

AI Technical Summary

Problems solved by technology

At present, there is no wind power slewing bearing manufacturer in China that has established a life calculation formula suitable for its own products. The main reason is that the establishment of the correction coefficient of the formula needs to be based on a large number of experiments and statistical data from practical applications. Experimental equipment for wind power slewing bearings to carry out complex loading and collect relevant signals
