Abstract

The invention discloses an end-axle box bearing which comprises a bearing sleeve, wherein a first inner bearing sleeve and a second inner bearing sleeve are arranged in the bearing sleeve; the first and second inner bearing sleeves are butted; clearances are arranged between the bearing sleeve and the first inner bearing sleeve as well as between the bearing sleeve and the second inner bearing sleeve; a plurality of rolling elements are respectively arranged between the bearing sleeve and the first inner bearing sleeve as well as between the bearing sleeve and the second inner bearing sleeve; one side of each rolling element is arranged in a movable slot on an inner wall of the bearing sleeve; the other side of each rolling element is in contact with the first or second inner bearing sleeve; a first retainer ring and a second retainer ring are respectively arranged at two ends of the butted first and second inner bearing sleeves; and the first retainer ring and the second retainer ring are butted with the rolling elements. The end-axle box bearing provided by the invention has the advantages of simple structure, convenience in realization, being applicable to a locomotive and convenience in the assembling of the bearing and the reliable running of the bearing.

Description

technical field [0001] The invention relates to bearing technology, in particular to an end-shaft axlebox bearing. Background technique [0002] With the promotion and application of railway technology, a large number of locomotives have been put into operation. During the high-speed operation of the locomotive, each part of the locomotive bears various forces. The quality of each part of the locomotive directly affects the performance of the locomotive. Among them, the bearing in the locomotive is a key component in the high-speed operation of the locomotive. It is mainly used to connect the transmission shafts in the locomotive and needs to withstand the impact of various forces. Therefore, the bearing performance of the locomotive has a greater impact on the overall performance of the locomotive. [0003] At present, two sets of single-row cylindrical roller bearings are generally used for the axle box bearings of locomotives. That is, during the locomotive manufacturing ...
