A high-speed planetary wheel bearing with high specific pressure and bidirectional rotation

Abstract

The invention relates to a bearing and specifically relates to the bearing for a bilateral rotating high-pressure-ratio high-speed planet gear. The bearing comprises a bearing body, a babbitt, a stop pin and a temperature measurer, wherein the babbitt is divided into two sections which are poured on the outer surface of the bearing body; the stop pin is arranged at a shaft end assembling the bearing body with a box; a certain rotating angle is formed between the stop pin and the babbitt; the temperature measurer is located in an alloy lateral hole of the bearing body; an annular slot is formed in the middle of the bearing body through a fastening glue; the babbitt is respectively poured onto the outer surface of the bearing body on the two sides of the annular slot; N oil feeding slots are arranged on the alloy surface of the babbitt; N oil guide holes and N oil inlets are arranged in the bearing body; the N oil guide holes are respectively communicated with N oil feeding slots; a central oil inlet of the bearing body is not thoroughly drilled, so that the oil inlet is formed into a chamber. The bearing for the bilateral rotating high-pressure-ratio high-speed planet gear has the advantages of reasonable structure design, long service life, support stability, oil feeding stability and compact structure.

Description

technical field [0001] The invention relates to a bearing, in particular to a bearing applied to a bidirectional rotation large specific pressure high-speed planetary wheel. Background technique [0002] In general-purpose transmissions, main transmissions of ground transportation machinery, and aviation drive devices, most planetary gears are supported by rolling bearings. High speed and heavy load requirements. At this time, the bearing of the planetary wheel is the heaviest supported support in the planetary transmission. Generally, sliding bearings are used. The main reasons are: the load bearing capacity of rolling bearings is much smaller than that of sliding bearings of the same volume. Vibration and noise are relatively large, especially in the later period of use, and the life of rolling bearings is generally lower than that of sliding bearings. Therefore, it is very necessary to design a high-speed planetary wheel bearing for bidirectional rotation with high speci...
