Abstract
The utility model discloses a low noise motor. The utility model is characterized in that a stator and a rotor are arranged in a machine casing; the rear part of the rotor is provided with a damping board; a front end cover is arranged on the front end of the machine casing and is provided with a skeleton oil seal and a rotor bearing; the rear end part of the machine casing is provided with a rotor bearing, and a damping post is arranged on the rear end part of the machine casing on the periphery of the rotor bearing; the base of the damping post leans on the outer end surface of the damping board, and the end part of the damping post is provided with a convex post sheathed with one end of a damping spring; the convex post is thinner than the damping post, the outer diameter of the convex post is corresponding to the inner diameter of the damping spring, and thus the damping post and the spring becomes a component. The damping post can bear relatively stable spring force during the operation of a motor, a damping cover board is arranged on the rear end of the machine casing, and the other end of the damping spring leans on the inner surface of the damping cover board. The structure can reduce noise generated by a damping part, and the connection of the damping part is reliable and safe further.
Description
Technical field
The utility model relates to a kind of low noise motor.
Background technology
Band damping motor mainly is in order to make motor fast braking after outage, after the motor outage, to utilize the frictional force between damping post and the damping sheet that rotor is stopped operating fast, reaching the purpose of braking.In original damping structure, the damping post is an optical axis, be not fixedly coupled relation between spring and the damping post, in the process of motor operation, the power of the spring that the damping post is subjected to will produce periodic vibrations, and then can produce noise owing to unfixed relation, simultaneously because the friction between damping post and the damping sheet also can produce noise, overall noise when the factor of this two aspect will influence the motor operation.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, the utility model provides a kind of low noise motor.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of low noise motor, comprise casing, be provided with stator and rotor in the casing, the rearward end of described rotor is provided with damping sheet, rearward end at casing is provided with several damping posts, the base portion of damping post is by on the outer face that is located at damping sheet, and the end of damping post is provided with a projection, is arranged with an end of damping spring on the projection.
As preferably, described projection is slightly thin than the damping post, and the internal diameter of its external diameter and described damping spring is suitable; Described damping post is provided with 3-5, and is evenly arranged in the slotted eye of rear end of casing.
As preferably, the rear end of described casing is provided with the damping cover plate, and the other end of described damping spring is by on the inner surface that is located at the damping cover plate.
Therefore, the utility model is simple in structure, and is rationally distributed, and the damping post is a multidiameter, on the basis of former damping post, process one section size of an end, and this section will be used to spring is connected on the damping post, damping post and spring will become parts like this, in the process of motor operation, the spring force that the damping post is subjected to is metastable, will produce the influence of three aspects like this to the use of motor: reduce the noise that damping portion produces, and also helpful to the noise that reduces motor integral body; Connection between damping post and the spring is more reliable, and safety helps the stable operation of motor; With prolonging the useful life of damping post, help the operation and maintenance of motor.
