Accompanying drawing explanation
Fig. 1 is the structural representation of the split washer of motor according to the embodiment of the present invention.
Reference numeral: the split washer 1 of motor, back-up ring body 10, opening 11, interior along 12, weightening finish portion 20, loss of weight portion 30.
Embodiment
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the present invention, and can not limitation of the present invention be interpreted as.
Below with reference to the accompanying drawings split washer 1 according to the motor of the embodiment of the present invention is described.
As shown in Figure 1, back-up ring body 10, weightening finish portion 20 and/or loss of weight portion 30 is comprised according to the split washer 1 of the motor of the embodiment of the present invention.
Back-up ring body 10 is for having the annular of opening 11.Back-up ring body 10 can be arranged in weightening finish portion 20 and loss of weight portion 30, also weightening finish portion 20 and loss of weight portion 30 can be set simultaneously.Wherein, weightening finish portion 20 is located at the position of the adjacent openings 11 of back-up ring body 10.Loss of weight portion 30 is located at the position away from opening 11 of back-up ring body 10.The center of gravity of split washer 1 overlaps with the center of circle of the interior of back-up ring body 10 along 12 place circumference.
According to the split washer 1 of the motor of the embodiment of the present invention, by adjacent openings 11 place at back-up ring body 10, weightening finish portion 20 is set, and/or at back-up ring body 10, loss of weight portion 30 is set away from opening 11 place, weightening finish portion 20 can be utilized like this to increase the weight at adjacent openings 11 place of back-up ring body 10, loss of weight portion 30 is utilized to reduce the weight away from opening 11 place of back-up ring body 10, the center of gravity of split washer 1 entirety can be adjusted thus, eliminate self laying particular stress on of split washer 1, the center of gravity of split washer 1 entirety is overlapped with the center of circle of the interior of back-up ring body 10 along 12 place circumference, split washer 1 is assembled to after on motor shaft, the unbalancing value of rotor can not be changed, thus the vibration that can not increase when motor runs.
Below with reference to the accompanying drawings split washer 1 according to the motor of the specific embodiment of the invention is described.
In specific embodiments more of the present invention, as shown in Figure 1, back-up ring body 10, weightening finish portion 20 and/or loss of weight portion 30 is comprised according to the split washer 1 of the motor of the embodiment of the present invention.
Advantageously, as shown in Figure 1, the position of the adjacent openings 11 of back-up ring body 10 is provided with weightening finish portion 20, and the position away from opening 11 of back-up ring body 10 is provided with loss of weight portion 30.That is, back-up ring body 10 is arranged simultaneously weightening finish portion 20 and loss of weight portion 30, both can increase the weight at opening 11 place of back-up ring body 10 thus, the weight away from opening 11 place of back-up ring body 10 can be reduced again, more be convenient to the overall center of gravity regulating split washer 1.
In order to ensure the overall construction intensity of split washer 1, back-up ring body 10, weightening finish portion 20 and loss of weight portion 30 are one-body molded.That is, split washer 1 is integrated part.
In concrete examples more of the present invention, as shown in Figure 1, weightening finish portion 20 is two, and two weightening finish portions 20 lay respectively at the both sides of opening 11, two weightening finish portions 20 with the central axis L of opening 11 for symmetry axis is symmetrical arranged.Weightening finish portion 20 not only can be utilized thus to increase the weight of the opening 11 of back-up ring body 10, and two weightening finish portions 20 are symmetrical arranged, can ensure that the overall center of gravity of split washer 1 can not to any one direction skew in opening 11 both sides.
Specifically, as shown in Figure 1, two weightening finish portions 20 are located on the periphery wall of back-up ring body 10 respectively, the upper surface in weightening finish portion 20 is concordant with the upper surface of back-up ring body 10, and the lower surface in weightening finish portion 20 concordant with the lower surface of back-up ring body 10 (above-below direction is as shown in the arrow A in accompanying drawing).Such split washer 1 can ensure that two weightening finish portions 20 can not interfere mutually with other structure of motor, thus facilitate the assembling of split washer 1 after assembling.In addition, can also ensure that the setting in weightening finish portion 20 can not cause the overall center of gravity of split washer 1 to offset in the vertical direction.
In specific embodiments more of the present invention, as shown in Figure 1, loss of weight portion 30 is for being located at the groove of the position away from opening 11 of back-up ring body 10, namely groove is offered to form loss of weight portion 30 in the position away from opening 11 of back-up ring body 10, thus can reduce the weight away from opening 11 place of back-up ring body 10.
Advantageously, as shown in Figure 1, on the periphery wall that loss of weight portion 30 is located at back-up ring body 10 and through along the vertical direction back-up ring body 10, to ensure that the setting in loss of weight portion 30 can not cause the overall center of gravity of split washer 1 to offset in the vertical direction.Loss of weight portion 30 is relative in the radial direction of back-up ring body 10 with opening 11, can ensure that the setting in loss of weight portion 30 can not cause the overall center of gravity of split washer 1 to any one direction skew in opening 11 both sides like this.
