Rail transit gearbox

Abstract

The invention belongs to the field of traffic, and particularly relates to a rail transit gearbox. The rail transit gearbox comprises a gearbox, wherein the gearbox comprises an upper box body and a lower box body which are arranged up and down, and an input shaft hole and an output shaft hole which penetrate through the interior are formed in the front side wall and the rear side wall of a connecting whole of the upper box body and the lower box body respectively; an input shaft penetrates through the input shaft hole, the outer wall of the end, penetrating into the input shaft hole, of the input shaft is sleeved with a main gear arranged in the gearbox, and an output shaft penetrates through the output shaft hole; and a lubricating device is arranged in the lower box body of the gearbox, lubricating oil in a lubricating oil tank is coated on the outer wall of the main gear in the rotating process of the gear, the lubricating oil on the main gear is supplemented, the problem of lubricating oil consumption caused by meshing of the main gear and an auxiliary gear can be solved, sufficient lubricating oil between the main gear and the auxiliary gear is guaranteed, stable transmission of power of the gearbox is achieved, and the problem that the gearbox needs to be detached for adding lubricating oil due to insufficient lubricating oil is solved.

Description

technical field [0001] The invention relates to the transportation field, in particular to a rail transit gear box. Background technique [0002] Rail transit refers to a type of vehicle or transportation system that operating vehicles need to run on a specific track. During the operation of a rail vehicle, a gearbox needs to be used to connect power equipment, and the force is carried out through the meshing of internal gears and bearings. conduction. [0003] There are following problems in prior art: [0004] When the existing rail transit gearbox is working, the lubrication between the gears directly affects the power output efficiency. The existing lubrication operations are mostly regular lubrication operations. During the use, the lubricating oil attached to the gear surface is gradually consumed, resulting in a decline in power output. , it is necessary to shut down the gear box for maintenance and lubricating oil coating, and it takes a lot of time to disassemble ...

Problems solved by technology

[0004] When the existing rail transit gearbox is working, the lubrication between the gears directly affects the power output efficiency. The existing lubrication operations are mostly regular lubrication operations. During the use, the lubricating oil attached to the gear surface is gradually consumed, resulting in a decline in power output. , it needs to be shut down for maintenance of the gears in the gearbox and coating of lubricating oil. It takes a lot of time to disassemble the gearbox, which is inconvenient for disassembly and maintenance.
