Problems solved by technology

During the working process of the gearbox under high working conditions, the stability of the gearbox is poor, and the gears are severely worn
Not only the meshing wear between the gears is serious, but also the bearing between the drive shaft and the box is easy to wear, the lubricating oil in the conventional gearbox can only lubricate the gears inside the gearbox, and cannot solve the problem of bearing lubrication

Abstract

The invention discloses a novel high-speed motor train unit gear box. An annular chamber which comprises an upper oil collection cavity and a lower oil collection cavity is formed in a gear box main body, an input end bearing and an output end bearing are communicated with the upper oil collection cavity and the lower oil collection cavity respectively, and with the rotation of an output end gear, lubricating oil flows in the annular chamber, flows into the input end bearing from the upper part, lubricates the input end bearing, and then returns to the lower oil collection cavity, so that circulation flowing of the lubricating oil is realized. On one hand, the output end gear, the input end bearing and the output end bearing can be lubricated continuously. On the other hand, through the circulation of the lubricating oil, heat dissipation can be accelerated, and the working stability can be improved.

Description

technical field [0001] The invention relates to the technical field of gearboxes, in particular to a novel gearbox for high-speed EMUs. Background technique [0002] The gearbox drive device of high-speed EMU is a key component to ensure the continuous and stable operation of high-speed trains, and it is a part of the train power bogie. One end of the gearbox is fixed on the frame, and the other end is installed on the axle, and is connected with the traction motor of the EMU through a coupling to realize power transmission. During the working process of the gearbox under high working conditions, the stability of the gearbox is poor, and the gears are severely worn. Not only the meshing wear between the gears is serious, but also the bearing between the drive shaft and the box is easy to wear. The lubricating oil in the conventional gearbox can only lubricate the gears inside the gearbox, and cannot solve the problem of bearing lubrication. Contents of the invention [0...
