The paper research a predominant variable torque clutch ? hyperboloid clutch with rollers . the clutch makes convert mutually between force and torque reality to control transmission with special geometry relation and friction transmission . it is satisfy with the request of modern industry 本文所研究的是一种性能优越的可变扭矩加载器?双曲面滚柱加载器,利用加载器接触表面特殊几何关系,通过接触表面的摩擦传动,实现轴向力与转矩之间的相互转换,从而达到控制制动和传递动力的目的,可满足现代工业对加载装置的要求。
Based on the torque - speed characteristic curve of induction motors , analyses were done on changes in slip with an variation in frequency when an induction motor drives different kinds of loads , including those with constant torque , constant - maximum torque , variable torque ( except fans and pumps ) and constant power , as well as fans and pumps , the formulas to calculate the slip and the speed under different frequencies and loads were presented 摘要以异步电动机机械特性曲线为基础,分析了变频调速异步电动机在拖动恒转矩负载、恒最大转矩负载、变转矩(非风机和泵类)负载、恒功率负载以及风机和泵类负载时,转差率随频率变化的规律。
