Title
(EN) Cycloidal gear and speed reducer
(ZH) 一种摆线轮及减速机
Abstract
(EN)
The invention provides a cycloidal gear and a speed reducer and relates to the technical field of speed reducers. The cycloidal gear comprises a cycloidal gear body. The end faces of the cycloidal gear body are provided with grooves, first oil ways and second oil ways. The first oil ways surround the corresponding grooves. The two ends of each second oil way communicate with the corresponding first oil way and the corresponding groove correspondingly. Due to existence of the grooves, lubricant is stored in the grooves, and the second oil ways can guide the lubricant in the grooves to the firstoil ways. Since the first oil ways are arranged on the end faces on the periphery of the grooves, after the first oil ways are filled with the lubricant, the lubricant in the first oil ways can achieve the lubrication function on the end faces of the cycloidal gear body and the end faces of parts making contact with the cycloidal gear body, the situation that the end faces of the cycloidal gear body make dry friction with the components in contact with the cycloidal gear body is avoided, and the wear of the end faces of the cycloidal gear body is lowered.

本发明提供了一种摆线轮及减速机,涉及减速机技术领域。摆线轮包括:摆线轮本体,所述摆线轮本体的端面上设有凹槽、第一油路和第二油路,所述第一油路环绕所述凹槽设置,所述第二油路的两端分别与所述第一油路和所述凹槽连通。由于凹槽的存在,凹槽内会储存有润滑剂,第二油路能够将凹槽内的润滑剂引流进第一油路上,由于第一油路设置在凹槽周围的端面上,当润滑剂充满第一油路后,第一油路中的润滑剂能够对摆线轮本体的端面和与其接触的零部件端面之间起到润滑作用,防止摆线轮本体的端面与相接处的部件之间发生干磨的情况发生,降低对摆线轮本体端面的磨损。
