Accu Roll轧管机导盘传动联轴器的设计改进

Modification on Design of Accu-Roll Pipe Mill Guide Disc Drive System

分析了Accu Roll轧管机导盘传动系统鼓形齿式联轴器在大扭矩、大位移角工况且回转直径受限的条件下,鼓形齿齿形参数间的相互关系,提出了满足工况的特殊设计要点和方法,并在结构设计上采用薄壳等特殊截面形状,利用空心截面扭转特性来增大扭矩,通过改变其齿接触数和接触强度延长其使用寿命。

Analyzed in the paper is the relationship between the barreled tooth shape parameters of the barreled tooth coupling under the operation conditions like high torque,big displacement angle and the limited tactical diameter.As a result,tips and methods for a special design of the coupling is put forward to meet the said operation conditions,including the structure of special cross-sectional shapes like shell,increasing torque with hollow cross-section torsional characteristics and prolonging service life of the coupling by means of changing number of the engaging teeth and their engaging strength.
