Abstract
The utility model discloses a kind of motor stators with chocking construction, including casing and the motor stator being mounted in casing, semi-circular hole is respectively provided on motor stator cylindrical wall and motor case inner round wall, the semicircle orifice aperture is slightly less than the outer diameter of split ring pin, when motor stator is installed, motor stator is put into casing after motor stator is aligned with the semicircle hole location on motor case, gluing auxiliary it can enhance or not apply on demand between casing and motor stator, split ring pin is vertically pressed into circular hole by stator loading according to arrow direction afterwards in place, spring catch is acted on due to own resilient, it is fixed in hole.What the utility model used is fixed motor stator and casing with split ring pin, simplifies the installation process of motor stator 2, eliminates special equipment, reduces rejection rate, improves production efficiency.Tolerance fit precision between stator and casing can do higher, raising motor concentricity, while design for disassembly facilitates maintenance personal to repair motor.
Description
Technical field
The utility model relates to a kind of chocking constructions, and in particular to a kind of motor stator with chocking construction belongs to electricity
Machine manufactures field.
Background technique
Fixation for current motor manufacturer between stator and casing usually has following methods:
1. being packed into casing using indentation or hot cover process when installation using interference fit between stator and shell.
2. Nian Jie using glue between stator and shell.
3. being fixed between stator and shell using axial compression formula.
For above-mentioned existing fixed form, the shortcomings that each way, is as follows:
The disadvantages of 1. there is installation using interference fit needs special equipment, and installation difficulty is big, and risk is high, and installed
Journey high rejection rate can not be dismantled after installation.
2. using the mode that glue is bonded since glue effect needs certain interval, so there are finished product rotor stator is concentric
Poor problem is spent, and the shock resistance of glue bonding way and high-low temperature resistant ability are poor, and there are degradation risk, complete machines
Service life is shorter.
3. it is more complicated using the fixed electric machine structure of compression type, it causes mounting process complicated and is unfavorable for motor miniaturization.
Summary of the invention
Motor stator and motor case are fixed and the purpose of the utility model is to provide a kind of when needing repairing, it can letter
The chocking construction singly dismantled.
In order to reach above-mentioned technical purpose, there is provided a kind of electricity with chocking construction for the technical solution of the utility model
Machine stator, including casing and the motor stator being mounted in casing, the junction of the casing and motor stator is equipped with and can tear open
The split ring pin unloaded.
Preferably, the inner wall of the split ring pin is equipped with an opposing slot.
Preferably, the inner wall of the split ring pin is equipped with a through-hole.
The advantages of the utility model:
1, simple process, equipment and personnel requirement are lower；
2, antidetonation, temperature tolerance are good, high reliablity；
3, installation concentricity is high；
4, process is reversible, detachable to repair.

Specific embodiment
To be clearer and more comprehensible the utility model, hereby with preferred embodiment, and attached drawing is cooperated to be described in detail below.
As shown in Figure 1, being a kind of motor stator with chocking construction provided by the utility model, including casing 3 and peace
It is respectively provided with semi-circular hole on motor stator 2 in casing 3,2 cylindrical wall of motor stator and 1 inner round wall of motor case, it should be partly
Circular hole aperture is slightly less than the outer diameter of split ring pin 3, when motor stator 2 is installed, by half on motor stator 2 and motor case 3
Motor stator 2 is put into casing 3 after the alignment of round hole location, between casing 3 and motor stator 2 can on demand gluing auxiliary enhance or
Person does not apply, and split ring pin 1 is vertically pressed into circular hole by the loading of stator 2 according to arrow direction afterwards in place, and spring catch 1 is due to itself
Elastic force effect, is fixed in hole.
Since spring catch 1 acts on, stator 2 can not rotate in casing 3, stopping function be played, simultaneously because spring
Support elastic force of the pin 1 in hole, even if enhancing between stator 2 and casing 3 without gluing, the two is also not easy to move in the axial direction
It is dynamic.
The junction of the casing 3 and motor stator 2 is equipped with demountable split ring pin 1.
Further, the inner wall of the split ring pin 1 is equipped with the inner wall of an opposing slot 4 or the split ring pin 1
It is equipped with a through-hole 5, it is i.e. removable after being ticked spring catch 1 out of hole using specialist tools for when needing to remove stator 2
It unloads.
In practical operation, can according to motor maximum moment calculate spring catch suffered by shearing moment and according to motor stator it is long
Degree determines suitable spring catch length, selects specific spring catch model in conjunction with shearing moment and spring catch length.Model choosing
Semicircle orifice opening diameter is determined according to spring catch elasticity after fixed, have enough frictional force to ensure spring catch in hole and one can be provided
Fixed axial retention effect.
What the utility model used is fixed motor stator and casing with split ring pin, simplifies the peace of motor stator 2
Dress process eliminates special equipment, reduces rejection rate, improves production efficiency.Tolerance fit precision between stator 2 and casing 3 can
It is higher with what is done, improve motor concentricity.High reliability and high life reduce user's maintenance cost, while design for disassembly side
Just maintenance personal repairs motor.
