Problems solved by technology

[0004] The purpose of the present invention is to provide a structure to prevent the cast aluminum rotor of an explosion-proof motor from falling back, so as to solve the above-mentioned background technology. When screening, the dust mixed in the material will fly up, which is not easy to be screened out, but easy to accumulate. On the sieve, it will cause blockage of the mesh and affect the working efficiency of the sieving.

Abstract

The invention discloses a structure for preventing the cast aluminum rotor of an explosion-proof motor from retracting a shaft, which comprises a cast aluminum rotor and a rotating shaft. The cast aluminum rotor is heat-sleeved on the rotating shaft, and the rotating shaft is provided with an iron core gear, an iron core gear block and a bearing gear. The iron core gear is arranged in the middle of the rotating shaft as the positioning joint of the cast aluminum rotor, and the outer diameter of the cast aluminum rotor is D and the length is L; The distance from the bearing gear root to the iron core gear platform root is L2; L1- L2 is the retraction of the cast aluminum rotor. As that retraction amount is preset on the rotate shaft, the one-time qualified rate of the motor assembly is ensure, and the manufacturing cycle of the motor is greatly shortened. The structure can ensure the performance and quality of the motor, and can ensure the qualified rate of the motor.

Description

technical field [0001] The invention relates to the technical field of vibrating screens, in particular to a structure for preventing cast aluminum rotors of explosion-proof motors from falling back. Background technique [0002] The vibrating screen works by using the reciprocating rotary vibration generated by the vibration of the vibrator. The upper rotating weight of the vibrator causes the screen surface to generate plane circular vibration, while the lower rotating weight causes the screen surface to generate conical rotary vibration. The effect is to make the screen surface produce double-rotation vibration. [0003] However, when the existing vibrating sieve is sieving, the dust mixed in the material will fly, and it is not easy to be sieved out, but it is easy to accumulate on the sieve, resulting in blockage of the mesh and affecting the working efficiency of the sieving. In view of the above problems, it is urgent to carry out innovative design on the basis of th...
