Description
Technical field
The utility model relates to a kind of stretching end cap, is specifically related to a kind of precision circularity stretching end cap, belongs to technical field of motors.
Background technology
Along with the development of science and technology, the use of the various rotor of electromechanics trade gets more and more, various stretching end cap also gets more and more, and the end cap that stretches generally refers to that axial dimension is greater than the lid at the motor two ends of radial dimension, Main Function is the locus of the axle determining rotor, certain needs and multi-form bearing fit, be connected on the shell of fixed electrical machinery stator by stretching end cap, ensure the gap of rotor and stator, stretching end cap is used to be one of important feature kind of motor, but the circularity of end cap iron core shelves and particularly important to motor with the axiality of bearing chamber, when end cap iron core shelves circularity and can motor noise be had a strong impact on when changing with the axiality of bearing chamber.
Utility model content
The technical problems to be solved in the utility model is the existing defect of customer service, provides a kind of light R-T unit of safe grating, by square top iron and screw core method, end shelves circularity precision can improve a training, material can reduce by more than 20%, can reduce motor noise, effectively can solve the problem in background technology.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A kind of high accuracy circularity stretching end cap of the present utility model, comprise end cap body, form cavity in the middle of described end cap body, described end cap bodies top is provided with end cap panel, is provided with groove in the middle of described end cap panel, base plate is provided with in the middle of described groove, be provided with bearing pedestal in the middle of described base plate, described end cap body bottom is provided with opening, and opening surrounding is provided with stretching end cap, described stretching end cap periphery is provided with flange, and described stretching end cap is provided with bolt.
As a kind of optimal technical scheme of the present utility model, described flange is the wide flange of 1 ~ 10mm.
As a kind of optimal technical scheme of the present utility model, described bolt is equidistant to be located on stretching end cap and to be four.
The beneficial effect that the utility model reaches is: use stretching end cap to be one of important feature kind of motor, the circularity of end cap iron core shelves and particularly important to motor with the axiality of bearing chamber, have a strong impact on motor noise, adopt this new design side top iron and screw core method, end shelves circularity precision can improve a training, material can reduce by more than 20%, can reduce motor noise.

Number in the figure: 1, end cap body; 2, end cap panel; 3, groove; 4, base plate; 5, bearing pedestal; 6, stretching end cap; 7, flange; 8, bolt.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
Embodiment: a kind of high accuracy circularity stretching end cap as shown in Figure 1-2, comprise end cap body 1, form cavity in the middle of described end cap body 1, described end cap body 1 top is provided with end cap panel 2, is provided with groove 3 in the middle of described end cap panel 2, base plate 4 is provided with in the middle of described groove 3, be provided with bearing pedestal 5 in the middle of described base plate 4, described end cap body 1 bottom is provided with opening, and opening surrounding is provided with stretching end cap 6, described stretching end cap 6 periphery is provided with flange 7, and described stretching end cap 6 is provided with bolt 8.
Described flange 7 is the wide flange 7 of 1 ~ 10mm.End cap intensity can be increased by flange 7, make it not yielding.Described bolt 8 is equidistant to be located on stretching end cap 6 and to be four.End cap can be fixed by bolt and connect motor top.
It should be noted that, the flange 7 that 1 ~ 10mm is wide is together increased at the ragged edge of tradition stretching end cap, increase end cap intensity, improve end cap iron core shelves circularity, thickness can be used simultaneously to reduce by the material punching of 20%, stretching end cap is used to be one of important feature kind of motor, the circularity of end cap iron core shelves and particularly important to motor with the axiality of bearing chamber, has a strong impact on motor noise, adopts this new design side top iron and screw core method, end shelves circularity precision can improve a training, can reduce motor noise.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although be described in detail the utility model with reference to previous embodiment, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
