Abstract

The invention discloses a self-ventilation traction motor. The motor comprises a shell, a driving shaft and a rotor; the rotor is connected with one side of the interior of the shell, the driving shaft is connected with one end of the rotor, an air inlet cover is connected with one side of the exterior of the shell, an air outlet cover is embedded into the top end of one side of the outer wall ofthe shell, and liquid storage hoppers are arranged on the two sides of the outer wall of the rotor respectively. Blades are connected to the top end of the exterior of the driving shaft in a sleevingmode, air inlet pipes are installed at the top ends of one sides of the outer walls of the liquid storage hoppers in an embedded mode, and pressure balancing pipes are installed on one sides of the outer walls of the two liquid storage hoppers. The blades are driven by the driving shaft to rotate, so that external gas is fed into the shell from the air inlet cover; and heat generated in the shellis absorbed. Meanwhile, lubricating oil liquid is injected into the rotary connecting position of the driving shaft from the liquid inlet pipe through the pressure balancing pipes, so that the ventilation and heat dissipation performance of the interior of the traction motor is achieved, and automatic lubrication of the connecting position of the driving shaft is achieved.

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 ...
