Abstract

The invention discloses a self-ventilating traction motor. It includes a housing, a drive shaft and a rotor, the rotor is connected to the inner side of the housing, the drive shaft is connected to one end of the rotor, the air intake cover is connected to the outer side of the housing, the The air outlet cover is embedded and installed on the top of one side of the outer wall of the housing, the liquid storage buckets are respectively opened on both sides of the outer wall of the rotor, the blades are sleeved on the outer top of the drive shaft, and the air intake pipe is embedded and installed on the outer wall of the rotor. The top of one side of the outer wall of the liquid storage hopper, the pressure balancing tube is installed on one side of the outer wall of the two liquid storage hoppers, the invention drives the blades to rotate through the drive shaft to send the outside air into the shell from the air inlet hood, and the The heat generated inside the shell is absorbed, and at the same time, the lubricating oil is injected from the liquid inlet pipe to the rotating connection of the drive shaft through the equal pressure pipe, thereby realizing the ventilation and heat dissipation performance of the traction motor inside, and realizing the protection of the drive shaft connection. Automatic lubrication.

Description

technical field [0001] The invention relates to the technical field of motor equipment, in particular to a self-ventilating traction motor. Background technique [0002] Motors used for traction on railway mainline electric locomotives, industrial and mining electric locomotives, electric drive diesel locomotives and various electric vehicles. Traction motors include traction motors, traction generators and auxiliary motors. The working principle of traction motors is the same as that of general DC motors, but there are special working conditions. To withstand considerable shock and vibration. [0003] However, the existing traction motors cannot achieve ventilation and heat dissipation inside the traction motor and automatic lubrication of the connection of the drive shaft during use, resulting in poor stability of the traction motor during operation. Contents of the invention [0004] The purpose of the present invention is to provide a self-ventilating traction motor ...
