建立了一种新的测试装置，用于测量与价值列车中其他摩擦部件隔离的单个凸轮-举升副之间的界面摩擦。对常规举升器和滚筒举升器进行了详细的研究。测量结果表明，使用滚轮举升器可以减少80%的摩擦，并且两种类型的举升器的摩擦都有随发动机转速降低的趋势。观察到在接触循环的任何部分都没有摩擦减少，并且在常规举升器的情况下，摩擦系数很大，排除了接触处弹性流体动力润滑的可能性。1986年5月12日至15日在加拿大安大略省多伦多举行的第41届年会上发表
A novel test apparatus was built to measure the interface friction between a single cam-lifter pair isolated from other frictional components in the value train. Detailed investigations were made, for both a conventional lifter and a roller lifter. Measured results showed an 80 percent reduction in friction with the use of the roller lifter and the trend of decreasing friction with engine speed for both types of lifters. The observed lack of friction reduction over any part of the contact cycle and the large coefficient of friction in the case of the conventional lifter ruled out the possibility of elastohydrodynamic lubrication at the contact.
