2018-5-30 Questions connected with the determination of the dynamic loads arising in the mobile components of a planetary mill with a gear drive are considered. The influence of the structural and technological parameters on the magnitude of the loads is analyzed. A horizontal planetary mill with external (respectively, internal) spinning of the grinding drums was selected to conduct the study.

2021-5-14 defined on the bearings and not only the thermal characteristics may be different between measurement and prediction, but the resulting rotordynamic performance can vary as well. Consider three cases: a double helical gear with no thrust control, a single helical gear with thrust bearing and a single helical gear with thrust collars.

2016-5-21 abrasive material can cause premature bearing failure, abnormal gear wear and can damage shaft journals for oil seals. Infiltration of corrosive gases, liquids (including water) or solids can result in corrosive chemical reactions on bearing, gear and seal contact surfaces that can cause premature failure or abnormally high wear rates.

gear stage and a planetary gear stage. These gear units are equiped with rolling bearings, too. For coal mills with medium to high power the KMPP gear units are deployed, which offer a high power density by using two planetary gear stages. These gear units are equiped with sliding bearings, as this solution is able to absorb dynamic loads even ...
