Problems solved by technology

Among the gears and bearings participating in the transmission, the gearbox needs to send relative sliding or movement during operation, so friction and wear will occur, which will increase power consumption and reduce transmission efficiency; especially for high-speed transmission, it is even more necessary to consider the lubrication of the gearbox
The quality of its lubrication system will affect the thermal balance of the entire gearbox and the wear of gears and bearings; in severe cases, it will also cause overheating or burning of gear segment teeth and bearings, which will seriously affect the quality and service life of the gearbox
[0003] At present, the...

Abstract

The invention relates to the technical field of a rail vehicle transmission system, and discloses a traction gear box and a rail vehicle. The traction gear box comprises a gear box body, a driving gear assembly, a driven gear assembly and an oil accumulation tank, wherein an accommodation cavity is constructed inside the gear box body; the driving gear assembly is arranged in the accommodation cavity; the driven gear assembly is meshed with the driving gear assembly; an oil pool for containing lubricating oil is constructed at a position in the accommodation cavity, which corresponds to the lower part of the driven gear assembly; the lower end of the driven gear assembly is infiltrated in the lubricating oil in the oil pool; the oil accumulation tank is formed on the inner wall of the gearbox body and positioned above the driving gear assembly; the oil accumulation tank is used for bearing the lubricating oil shaken by rotation of the driven gear assembly; an oil inlet passage is constructed inside the driving gear assembly; and the oil inlet passage is communicated with the oil accumulation tank through an oil inlet hole formed on the gear box body. The traction gear box has theadvantages of high lubricating efficiency and good lubricating effect.

Description

technical field [0001] The invention relates to the technical field of rail vehicle transmission systems, in particular to a traction gearbox and a rail vehicle. Background technique [0002] The lubrication system of the gearbox has the functions of lubrication, cooling, cleaning, rust prevention, sealing and hydraulic pressure. Among the gears and bearings involved in the transmission, the gearbox needs to send relative sliding or movement during operation, so friction and wear will occur, which will increase power consumption and reduce transmission efficiency; especially for high-speed transmission, it is even more necessary to consider the lubrication of the gearbox. The quality of its lubrication system will affect the thermal balance of the entire gearbox and the wear of gears and bearings; in severe cases, it will also cause overheating or burning of gear segment teeth and bearings, which will seriously affect the quality and service life of the gearbox. [0003] At...
