Abstract

The utility model relates to a motor, concretely relates to motor that contains rotor and gear elastic connection structure. In the prior art, the rotor of the motor and the associated gear structure can cause the rotor to collide with the housing, thereby generating obvious noise. To the above-mentioned defect among the prior art, the utility model provides a motor that contains rotor and gear elastic connection structure. The utility model discloses a contain coupling mechanism's motor except including rotor assembly, inferior valve, stator group, lead wire group, upper cover, gear train, the center pin outside, rotor assembly still contains rotor, gear and spring. The utility model discloses a motor that contains rotor and gear elastic connection structure, rotor assembly are when the circular telegram is rotatory, because of the elastic support that is the spring in the middle of the rotor assembly, so eliminate the clearance with the upper cover, rotor assembly can not the drunkenness from top to bottom in service to the noise has been reduced by a wide margin.

Description

Motor with rotor and gear elastic connection structure

Technical Field

The utility model relates to a motor, concretely relates to motor that contains rotor and gear elastic connection structure.

Background

The motor is an electromagnetic device for realizing electric energy conversion or transmission according to an electromagnetic induction law, is used as an important component of a transmission and control system, and is widely applied to various industries. With the development of society and the progress of technology, people also pay attention to the noise performance of the motor while pursuing the control precision of the motor.

There are many causes of motor noise, and there are three main causes summarized as electromagnetic noise, aerodynamic noise, and mechanical noise. The assembly of the structure of the motor rotor and its associated gears is an important factor affecting mechanical noise.

In prior art, motor rotor and its gear that links generally have two kinds of structures, one is the integral type structure, and this structural design and processing are simple, but in the rotor rotation process, because of the centrifugal force effect, the rotor can be around the central axis drunkenness from top to bottom in the motor, collides with motor casing, produces obvious noise, leads to the motor noise can not satisfy the requirement of customer to the silence. The second is that the rotor is rather than subsidiary gear design segmentation structure, and both are put together through the draw-in groove, can separate from top to bottom, control the tight fit to make the rotor can hold the synchronous gear and rotate, this structural assembly is more complicated, is suitable for the great rotor group of size, because of its size is big, be not convenient for integrated processing, nevertheless can not satisfy the requirement of user to the silence because of the play produces obvious noise from top to bottom equally.

SUMMERY OF THE UTILITY MODEL

There is the great defect of motor noise to the structure of electric motor rotor and its associated gear among the prior art, in order to reduce the motor noise, the utility model provides a contain rotor and gear elastic connection structure's motor.

The motor with the elastic connection structure of the rotor and the gear comprises a rotor set, a lower shell, a stator set, a lead set, an upper cover, a gear set and a central shaft, wherein the rotor set further comprises a rotor, a gear and a spring, and the spring is positioned on the inner side of a rotor clamping groove and a gear interface of the motor.

For the motor with the elastic connection structure of the rotor and the gear, the central shaft is fixed on the lower shell and is supported by the upper cover at the top, the rotor set is sleeved on the central shaft and can rotate, the stator set is arranged at the bottom of the lower shell, the lead set is connected with the wiring terminal of the stator set, the gear set is arranged above the stator set and forms a driving matching body with the rotor set, and the upper cover is reversely buckled on the top surface of the lower shell and is riveted and fixed.

The utility model discloses a motor that contains rotor and gear elastic connection structure, the rotor assembly is when the circular telegram is rotatory, and rotor bottom supports with the inferior valve, and the gear supports with the upper cover, and because of the rotor assembly adopts the spring to part rotor and gear elasticity, its assembly can move about from top to bottom, reduces hard contact, so has eliminated the clearance with the upper cover, and the rotor assembly can not drunkenness from top to bottom in service to reduce the noise by a wide margin, satisfied the requirement of user to the silence.

Drawings

FIG. 1 is a schematic view of a connection structure of a motor rotor and a gear;

fig. 2 is a schematic view of a motor including the coupling mechanism.

Detailed Description

The drawings in the embodiments of the present invention will be combined to form a preferred embodiment of the present invention, rather than to form a complete embodiment of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, an elastic connection structure of a motor rotor and a gear comprises a rotor 1 and a gear 2, and is characterized in that: still be equipped with spring 3 between electric motor rotor and the gear, spring 3 is located the interior survey of electric motor rotor draw-in groove and gear interface.

As shown in fig. 2, an electric machine including the elastic connection mechanism includes a rotor set 9, a lower case 10, a stator set 7, a lead set 8, an upper cover 6, a gear set 5, and a central shaft 4, and the rotor set further includes a rotor, a gear, and a spring.

Preferably, the central shaft 4 is fixed to the lower casing 10 and supported by the top upper cover 6, the rotor assembly 9 is sleeved on the central shaft 4 and is rotatable, the stator assembly 7 is arranged at the bottom of the lower casing 10, the lead assembly 8 is connected with a binding post of the stator assembly 7, the gear assembly 5 is arranged above the stator assembly 7 and forms a driving matching body with the rotor assembly 9, and the upper cover 6 is reversely buckled on the top surface of the lower casing 10 and is riveted and fixed.

Compared with the prior art, the beneficial effects of the utility model are that: because the rotor and the gear are elastically separated by the spring, the combination body can move up and down, and hard contact is reduced. The utility model discloses a contain coupling mechanism's motor, rotor assembly are the elastic support of spring in the middle of the rotor assembly when the circular telegram is rotatory, so eliminate with the clearance of upper cover, the rotor assembly can not be drunkenness from top to bottom in service to the noise has been reduced by a wide margin, satisfies the requirement of user to the silence.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
