Gearbox bearing lubrication device

Abstract

The invention discloses a gearbox bearing lubrication device comprising a box, a mounting block, a planet gear and an inner toothed ring. The mounting block is provided with a fixed shaft. The planet gear is rotatably supported on the fixed shaft through a planet bearing. The planet gear meshes with the inner toothed ring. The inner toothed ring is fixedly connected with the box. The inner toothed ring is rotatably supported on the mounting block through a rotary support shaft. The fixed shaft is provided with an axial oil hole and a radial oil hole communicated with each other. An inlet of the axial oil hole is arranged at one end of the fixed shaft. An outlet of the radial oil hole leads to the planet bearing. The fixed shaft is provided with an oil collector; an inner cavity of the oil collector leads to the inlet of the axial oil hole. The box is provided with a plurality of oil cups; when rotating with the box, the oil cups can arrive above the oil collector. The gearbox bearing lubrication device has the advantages that the lubrication problem of the gearbox inner bearing can be solved, the cost is low and the structure is simple.

Description

technical field [0001] The invention relates to a gear box, especially a bearing lubricating device in a gear box in which a planetary gear train and a fixed shaft gear train coexist. Background technique [0002] In the existing gearboxes, especially in the side reduction gearboxes with large electric wheels and self-unloading wheels, the bearings above the lubricating oil level are often lubricated by splashing. There are disadvantages of poor lubrication and unreliability; there are also special nozzles or oil pipelines for forced lubrication. This structure requires a forced lubrication device, which is costly and complicated. Contents of the invention [0003] The purpose of the present invention is to provide a gear box bearing lubrication device which can solve the problem of lubrication of the bearings in the gear box and has low cost and simple structure. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a ...
