Abstract

The invention discloses an experimental table of a wind-driven generator pitching slewing support, comprising an axial loading frame, an axial force-loading cylinder, two same-specification pitching slewing supports to be experimented, a large gear, a left connecting board, a right connecting board, a slewing support-mounting base, an overturning moment loading arm, an overturning moment loading cylinder, a power-driving module and a radial force-loading cylinder. The invention can simulate the operation state of a wind-driven generator pitching slewing support under various complicated loads in a vertical mounting state, detect the starting moment of the pitching slewing support, monitor the resistance moment, roller abrasion amount, lubricant temperature and vibration signals in operation in real time and estimate the fatigue service life of the pitching slewing support.

Description

technical field [0001] The invention relates to a large-scale bearing test bench, in particular to a wind power generator pitch-variable slewing bearing test bench. Background technique [0002] The slewing ring can generally be regarded as a giant bearing, mainly composed of inner ring, outer ring, rolling elements, spacer blocks, etc. It is an indispensable part of almost all large parts that need to rotate relative to each other. At present, the mainstream MW-level wind turbines on the market are almost all variable-pitch wind turbines, whose main feature is that the root of each blade is connected to the hub through a set of pitch-variable slewing bearings. In recent years, the installed capacity of wind turbines at home and abroad has grown rapidly, which has driven the development of the wind turbine pitch slewing bearing industry. Many domestic and foreign manufacturers have put into production wind turbine pitch slewing bearings. However, the pitch slewing bearings ...
