摘要:Using annular rollers as planets is an ideal design of high speed planetary traction drive.In this paper,the deformations and stresses of the roller at assemblage and operation are solved,and the method of adopting hollowness as main parameter of the roller design is presented.Also,the hollowness selection region is studied.
摘要:Epicyclic belt transmission (EBT), a new type of mechanical transmission,is intrduced in this paper.Begining with the studing on EBT with single roller,the principle and kinematic characterstics of EBT with multiple rollers are studied,and the influential factors to the kinematic stability of EBT are analyzed in detail.The work of the present paper makes some necessary preparations for optimal design of EBT.
摘要:This paper discusses the visible appearance and microscopical appearance characteristics of gear failure by electric erosion,including striped pattern,cloudy pattern,and riverside pattern.
摘要:In this paper,the friction coefficient of sliding higher pair is reseached by means of analysis and experiment,and the effects of each parameter on the friction coefficient and the mechanical efficiency of worm gearing is explained.
摘要:A way of measuring transmission efficiency of gearing on a gear tester with mechanical closed power is given,and the formulas of calculating thetransmission efficiency of gear reducer from the testing results are developed.
摘要:The error of non circular gear is measured on the double flank contact tester,taking a cylindrical gear as the master gear.This method can not only be used to check the transmission quality of non circular gear in fixed axis,but also is suitable to solve some questions of checking the transmission quality of the gearing with variable center distance,and is easy to improve the measure precision of non circular gear.
摘要:A new system for measuring gear dynamic performance has been developed.The stability of the system has been verified in the Gear Dynmic Performance Testing Mackine.Being Compared with the traditional measuring methed,it′s disturbance resistance is better.The theoretical anlysis results is in line with the experiment results completely.
