【 摘 要 】

Aiming at the wear of rolling movable teeth reducer used in polar deep ice drilling, this paper studies the wear law of tooth profile and analyses the sliding rate of rolling movable teeth transmission. The study of sliding rate can effectively provide the basis for the design of rolling movable teeth reducer, and improve the wear resistance, transmission efficiency and service life of reducer. In this paper, according to the extreme cold environment in the polar region, the type of lubricating oil is selected so as to maintain a certain oil film thickness on the tooth surface, which is an important method to improve the service life of the reducer.
