Description

Motor shell capable of reducing eccentricity of motor

Technical Field

The utility model relates to the technical field of electric machines, concretely relates to reduce motor housing of motor eccentricity.

Background

The motor is composed of a shell and a motor main body arranged in the shell. The stator is installed in the shell, and a junction box used for controlling the winding mode of the stator is installed outside the shell. However, the conventional installation method of the junction box is to install the junction box in the middle outside the shell, and the installation method has the following disadvantages: the stator is located the tip position of shell, and the terminal box is located the middle part position of shell, and the concentricity of stator and terminal box is relatively poor, leads to the motor to send great noise and influence the operating stability and the reliability of motor during operation.

SUMMERY OF THE UTILITY MODEL

There is above-mentioned technical problem to prior art, the utility model provides a can reduce motor eccentricity's motor housing, this motor housing has reduced the noise of motor and has improved the stability of motor.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a reduce motor housing of motor eccentricity, includes the casing of tube-shape, be equipped with radiating fin on the casing, radiating fin follows the length direction extension of casing just forms a plurality of heat dissipation channels, the periphery side of casing is equipped with the terminal box, the terminal box is located the end of casing, the pressfitting has the stator in the casing, the stator is located under the terminal box, just the terminal box with the stator is in the long direction of cross section diameter of casing is arranged.

The junction box comprises a first wiring groove and a second wiring groove, and the first wiring groove and the second wiring groove are symmetrically distributed along the length direction of the shell.

The first wiring groove and the second wiring groove are both convex wiring grooves, and the abdomen ends of the convex wiring grooves of the first wiring groove and the second wiring groove are close to the symmetry axis of the first wiring groove and the second wiring groove.

The opening end of the shell is provided with a supporting sheet, and the supporting sheet is integrally connected with the junction box.

The support sheet and the radiating fins are distributed along the length direction of the shell.

The shell extends outwards to form three supporting legs, and the three supporting legs extend along the length direction of the shell and are uniformly distributed on the outer peripheral side of the shell.

The utility model has the advantages that:

the utility model discloses move the terminal department of motor casing with the terminal box to reduce the space in the terminal box, make shell internal diameter and the 100% contact of stator external diameter, thereby increased the concentricity of shell and stator, reduce motor casing's eccentricity then, effectively reduced the noise of motor and improved the stability of motor.

Detailed Description

The present invention will be described in detail with reference to the following embodiments and accompanying drawings.

Examples

The motor housing for reducing eccentricity of a motor disclosed in this embodiment, as shown in fig. 1-3, includes a cylindrical housing 1, where heat dissipation fins 2 are disposed on the housing 1, the heat dissipation fins 2 extend along a length direction of the housing 1 and form a plurality of heat dissipation channels 3, a terminal box 4 is disposed on an outer peripheral side of the housing 1, the terminal box 4 is located at a tail end of the housing 1, a stator (not shown in the figure) is press-fitted in the housing 1, the stator is located right below the terminal box 4, and the terminal box 4 and the stator are arranged in a direction of a cross-sectional diameter of the housing 1, so that a non-contact surface between an inner diameter 1 of the housing and an outer diameter of the stator is reduced to the maximum, concentricity of the housing 1 and the stator is increased, and eccentricity of the motor is reduced.

In this embodiment, the terminal box 4 includes a first wiring groove 5 and a second wiring groove 6, the first wiring groove 5 and the second wiring groove 6 are symmetrically distributed along the length direction of the housing 1, and the symmetrically arranged wiring grooves further reduce eccentricity.

In this embodiment, first wiring groove 5 with second wiring groove 6 is the type wiring groove of dogbone, first wiring groove 5 with the second wiring groove 6 two the belly end in type wiring groove is close to first wiring groove 5 with the symmetry axis of second wiring groove 6, type wiring groove conveniently connects and is convenient for form the concentricity.

In this embodiment, a support sheet 7 is disposed at an opening end of the housing 1, the support sheet 7 is integrally connected with the junction box 4, and the support sheet 7 not only plays a role in fixing the junction box 4, but also plays a role in heat dissipation.

In this embodiment, the supporting sheet 7 and the heat dissipating fins 2 are both distributed along the length direction of the housing 1, and at this time, the supporting sheet 7 and the heat dissipating fins 2 together play a role of heat dissipation.

In this embodiment, the casing 1 extends three supporting legs 8 outward, the three supporting legs 8 extend along the length direction of the casing 1 and are uniformly distributed on the outer peripheral side of the casing 1, and the three supporting legs 8 can be arranged to effectively facilitate the placement of the motor casing 1 on any side surface.
