Abstract
The invention discloses a high-speed motor structure comprising a housing, a front end cover, a bearing gland, a bearing and a rotating shaft. Ventilating ducts are arranged between the surface of the housing and an accommodation cavity; and cooling fins are arranged inside the ventilating ducts. The bearing gland consists of an outer bearing gland and an inner bearing gland; the outer bearing gland, the inner bearing gland, and the bearing successively sleeve the rotating shaft from the front end to the rear end of the rotating shaft. Besides, a plurality of tightening screw holes are formed in the outer bearing gland; and tightening bolts are arranged in the tightening screw holes and support and tighten the front end surface of the inner bearing gland. According to the high-speed motor structure, with the ventilating ducts and the cooling fins arranged in the ventilating ducts, an effective contact area between the motor housing and external air increases, so that the heat radiation rate can be improved. Besides, when the tightening bolts arranged at the outer bearing gland are screwed tightly, the tightening bolts will compress the inner bearing gland and thus the outer bearing gland moves forwardly relative to the rotating shaft, so that the thread gap between the outer bearing gland and the rotating shaft can be reduced and thus the dustproof effect can be improved.
