Embodiment Construction

[0014] Such as figure 1 As shown, the waterproof grinding head motor of the present invention includes a casing 10 , a stator core 20 with windings disposed in the casing 10 , and a rotor 30 located in the stator core 20 and supported by a motor shaft 100 . The rear end of the casing 10 is connected with a rear end cover 40, the rear end of the motor shaft 100 passes through the rear end cover 40, the rear end is fixed with a fan 50, and the rear end cover 40 is also fixed with a windshield covering the fan 50. 60. The front end of the casing 10 is connected with a front end cover 500, and the front end of the motor shaft 100 passes through the front end cover 500, and a grinding wheel seat 200 is fixed on the front end. ;

[0015] combine figure 2 As shown, there is a waterproof gap between the opposite end surfaces of the grinding wheel holder 200 and the front end cover 500 .

[0016] Specifically, the grinding wheel base 200 is interference-fitted on the motor shaft 1...

Abstract

The invention provides a waterproof grinding head motor which comprises a machine shell, a stator iron core and a rotor, wherein the stator iron core is arranged in the machine shell and provided with a winding, and the rotor is arranged in the stator iron core and is supported by a motor rotary shaft. The front end of the machine shell is connected with a front end cover, the front end of the motor rotary shaft penetrates out of the front end cover, the front end of the motor rotary shaft is fixedly provided with a grinding wheel base, waterproof gaps exist between the grinding wheel base and the end face opposite to the front end cover, the waterproof gaps sequentially comprise a first vertical gap, a maze matching gap, a second vertical gap, a slope gap and a vertical seam allowance matching gap from inside to outside in the radial direction, the width of the vertical section of the seam allowance matching gap and the width of the vertical section of the maze matching gap are 0.1-0.2 mm, the bottom of the slope gap is located on the grinding base side, and the top of the slope gap is on the front end cover side. Waterproof performance of the shaft end of the grinding head motor is improved, water is prevented from entering the inside of the motor and corroding parts, and the service life of the parts of the motor is prolonged.

Description

technical field [0001] The invention belongs to the technical field of motors, in particular to a grinding head motor. Background technique [0002] When the grinding head motor is grinding glass, when the grinding wheel is rotating, it needs to be accompanied by water column spray cooling, and the spray position is located at the end of the motor shaft. The water pressure of the spray is high, and the splashed water can easily enter the inside of the motor, causing corrosion to the components and eventually causing damage to the components. Therefore, it is necessary to design a waterproof structure at the shaft end of the grinding head motor to prevent water from entering the interior of the motor when the grinding head motor is working. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a waterproof grinding head motor to overcome the deficiencies in the prior art. [0004] In order to solve the problems of the...
