Effects of bearing clearance and atmospheric temperature on performance of pinion bearings of railway vehicles

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2020
In Japan, most of the gear units for transmitting driving force in railway vehicles employ one-stage speed reducers. The gear unit is composed of a pinion connected to a traction motor via a coupling mechanism, a gear installed on an axle, and a gear ...

Investigation of factors affecting the performance of pinion bearing for gear unit of railway vehicle

Nihon Kikai Gakkai ronbunshu, 2019
If bearings for gear units of railway vehicles are damaged by seizing, parts of the bearings come off and damage the gear and the gear box, which may lead to the leakage of the gear oil and the defective rotation of the wheel sets.

Linear slider supported by squeezed air films with self-propulsion mechanism based on floating height difference

Nihon Kikai Gakkai ronbunshu, 2017
Non-contact supports involving air or magnetic forces are used as guide supports for linear motion mechanisms. In the present study, non-contact supports are generated using the effect of the static pressure force produced by a squeezed air film.
