High speed gear spead increaser having automatic lubricating system

Abstract

The invention discloses a high speed gear speed increaser with auto-lubricating system, and its structure: an electric motor is connected with a low speed shaft, the low speed shaft engages with a high speed shaft by gear, an oil pump is installed on the low speed shaft, an oil circuit (a) is connected with a main oil tank, the oil pump, and a left-end ball bearing and an oil circuit (b); the oil circuit (b) is connected in turn with a filter, a cooler and an oil circuit block; the outlet of the oil circuit block is divided into three parts, one part is connected with an oil circuit (c) which is connected with a front radial bearing, one part is connected with an exhaust valve and another part is connected with an oil circuit (d); the oil circuit is connected in turn with a rear radial bearing, and two thrust bearings; one end of an oil circuit (e) is connected with the two thrust bearings and the other end is connected with a right-end ball bearing, the engaging place of the low speed gear and the high speed gear and a high level oil tank; an oil circuit (f) is connected with the high level oil tank and the main oil tank. The invention uses an electric machine to drive the speed increaser and the oil pump at the same time, having simple structure and good lubricating effect.

Description

Technical field: [0001] The invention relates to a mechanical transmission device, in particular to a gear speed increaser. Background technique: [0002] In the existing high-speed gear speed increaser and its lubrication system, the oil pump is driven by a separate motor, and it needs to be equipped with components such as a check valve or an electromagnetic device. Before the high-speed gear speed up The structure and use of the gearbox are complicated. Due to the high speed of the high-speed gear speed increaser, the speed range is generally 3000-30000r / min, so that the temperature of the bearings, meshing gears and other parts in the speed increaser is very high, resulting in high temperature of lubricating oil and decline in cleanliness, reducing the speed increase The service life of the gearbox. Invention content: [0003] The purpose of the present invention is to provide a high-speed gear speed increaser with an automatic lubrication system. The bearings and me...
