A three-phase asynchronous motor with quantitative lubrication

Abstract

The invention discloses a quantitatively lubricated three-phase asynchronous motor, which relates to the field of motor technology. The cover is provided with an oil injection channel and an oil supply tank. The end cover is provided with an oil control device. The oil control device includes a plug rod and a floating block. The plug rod is provided with a mounting groove. The bottom wall of the mounting groove is provided with a spring. There is a bristle segment on the surface, a cleaning brush on the plug rod, and a chip storage groove and an adsorption magnet on the end cover. By setting the oil control device, the amount of lubricating oil in the end cover is kept stable, so that the bearing is always in the best lubrication state and prolongs the service life of the bearing; by setting the adjustment column, the three-phase asynchronous motor can be installed vertically or horizontally The oil control device can work normally; the surface of the plug plate and the arc surface can be cleaned by setting the bristle section and the cleaning brush.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a three-phase asynchronous motor with quantitative lubrication. Background technique [0002] At present, the three-phase asynchronous motor is a type of motor that is powered by a 380V three-phase AC power supply (with a phase difference of 120 degrees) at the same time. Since the rotor and the stator rotating magnetic field of the three-phase asynchronous motor rotate in the same direction and at different speeds, there are slip, so it is called a three-phase asynchronous motor. With the accelerated pace of social and economic development, all walks of life are changing with each passing day. Various electrical equipment have been developed and applied to various occasions. Three-phase asynchronous motors have been widely used as power sources in many occasion. [0003] The existing Chinese utility model patent with authorized notification number CN204349659U discloses a speci...

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: the lubricating oil in the oil injection hole of the motor will be consumed during the operation of the motor, the lubricating oil will gradually decrease, and the lubricating effect on the bearing will also gradually decrease, and the lubrication of the bearing cannot be achieved. Play the best effect and affect the service life of the bearing, and adding too much lubricating oil will cause waste
