A reducer and its high-speed shaft bearing lubrication structure

Abstract

The invention provides a reducer and a high-speed shaft bearing lubricating structure of the reducer. The high-speed shaft bearing lubricating structure of the reducer comprises a box body, a bearing, an oil thrower, an end cover and an oil baffle disc. The oil baffle disc is fixedly connected with the end cover or the box body, and an annular gap communicated with an oil hole of the box body is formed between the oil baffle disc and the bearing. The oil baffle disc is fixedly connected with the end cover or the box body, and circumferential or axial positioning of the oil baffle disc can be achieved; an interval is reserved between the oil baffle disc and the bearing and forms the annular gap to serve as an oil returning hole; when the oil baffle disc is mounted, the fixing position on the oil baffle disc and the mounting position on the end cover or box body only need to be aligned, positions of other holes do not need to be considered, and a gap between the end cover and the oil baffle disc does not need to be considered, so that the mounting difficulty is reduced, and the assembling efficiency is improved. In addition, circumferentially-positioned pin holes and the oil returning hole for heat exchange do not need to be machined in the oil baffle disc, the structure is relatively simple, machining is facilitated, and the machining difficulty of the oil baffle disc is reduced.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, and more specifically relates to a speed reducer and its high-speed shaft bearing lubricating structure. Background technique [0002] Please refer to figure 1 , this figure is a structural schematic diagram of a high-speed shaft bearing lubrication structure of a reducer in the prior art; the high-speed shaft bearing lubrication structure consists of a box body 05, a bearing 01, an oil throwing pan 02, an end cover 04, and an oil retaining pan 06 Composition; wherein, the oil throwing pan 02 and the bearing 01 are set on the high-speed shaft 03 of the reducer, one end of the oil throwing pan 02 is positioned and matched with the shoulder of the high-speed shaft 03, and the bearing 01 is offset against the other end of the oil throwing pan 02 The oil retaining plate 06 is used to block the oil so that the bearing 01 is fully lubricated, and it is rotatably sleeved on the high-spe...

Problems solved by technology

[0004] In this way, when installing the oil retainer, it is necessary to align the oil return hole on the oil retainer with the oil hole of the box body accurately, and at the same time ensure that the pin holes of the oil retainer are accurately aligned with the positioning holes of the end cover, and also It is necessary to ensure an appropriate gap between the end cover and the oil retaining plate, which makes the installation difficult and affects the assembly efficiency

[0005] In addition, the oil return hole and the pin hole need to be processed separately on the above-mentioned oil retaining plate, and the two holes need to ensure a certain positional relationship, so as to ensure that the oil return hole and the oil hole on the box body are aligned at the same time, and the pin hole and the end The positioning holes on the cover are also centered, which makes it difficult to process the oil deflector
