Life Calculation of Swivel Arm Bearing of RV Reducer Considering Pitch Error of Cycloidal Gear
摘要
Abstract
Aiming at the problem that the swivel arm bearing of RV reducer being prone to failure,the RV-110E reducer was used as the research object to analyze the force on the swivel arm bearing.ADAMS software was used to establish the multi-body dynamics model of RV reducer.And Lundberg-Palmgren was used as the theoretical basis to calculate the life of swivel arm bearing,and analyze the influence of cycloid wheel pitch error on the life of swivel arm bearing.The results show that:the resultant force and component force of the loading force on the swivel arm bearing vary periodically,the loading force on the swivel arm bearing on the same cycloid wheel has the same magnitude and period,and the phase difference is 120°,the maximum loading force on the swivel arm bearing is 8 094.6 N,and the minimum loading force is 1 371.2 N;the theoretical life of the swivel arm bearing is 4 629.0 h,and the simulated life is 2 505.6 h;when the starting value of the tooth pitch error is positive,the loading force of the bearing is larger than that without error,and vice versa;the larger the tooth pitch error,the wider the amplitude of the peak loading force of the swivel arm bearing,the higher the life stability of the swivel arm bearing,and vice versa.关键词
