Description

Grease injection and discharge mechanism of vertical motor Technical Field The utility model belongs to the technical field of vertical motors, and particularly relates to a grease injection and discharge mechanism of a vertical motor. Background The grease is discharged from the motor to remove impurities, moisture and unavoidable pollutants in the motor so as to keep the motor to normally run, and if the grease discharge port is accumulated and blocked, poor heat dissipation and overhigh temperature of the motor can be caused, and the service life of the motor can be influenced when serious, In the prior art, because the motor bearing is in a high-temperature running state for a long time, the bearing grease is blackened and solidified, the viscosity is higher, the grease with poor fluidity is conventionally removed from the motor and then manually cleaned in the industry, so that great trouble is brought to operators, production output and benefits of a factory are reduced due to shutdown and production stopping, although part of the grease can be cleaned through the use of an oil pump, part of the blackened and solidified grease cannot be completely cleaned, the temperature rise of the bearing is still difficult to completely avoid due to friction heat generated by accumulated and solidified grease, the cleaning effect of the grease in the vertical motor is reduced, and the problem of shortened service life of the vertical motor is also caused.
