无级变速器是适应现今生产、操作过程机械化、自动化发展及一般机器改善工作性能所必需的一种传动装置。它的功能特征主要是使输入轴在转速不变的情况下,实现输出轴的转速能在一定范围内连续变化、调节以满足机械或生产系统在运转过程中各种不同工况的需要。其中有在驱动功率固定的情况下,因工作阻力变化而需要调节转速以产生相应的驱动力矩者(如化工行业中的搅拌机械,要求随着搅拌物料的粘度、阻力增大而能相应减慢搅拌速度);有根据工况要求需要调
Continuously variable transmission is to adapt to today’s production, operation of the mechanization, automation and development of general machinery to improve performance required for a transmission. Its main feature is to make the input shaft rotate at the same speed, the output shaft speed can be continuously changed within a certain range, adjusted to meet the mechanical or production system in operation in a variety of working conditions needs. Among them, when the driving power is fixed, the speed needs to be adjusted due to the change of working resistance to generate the corresponding driving torque (for example, the mixing machinery in the chemical industry requires that the resistance be slowed down correspondingly with the viscosity of the stirring material, Stirring speed); according to the conditions required to adjust
