Abstract
The utility model discloses a limiting retainer ring for an output shaft of a starting motor. The limiting retainer ring can effectively prevent gears of a clutch from slipping out of an output shaft and comprises a retainer ring body, wherein the cross section of the retainer ring body is polygon, wherein the number of the edge of the polygon is within the range of 4-9, preferably, the cross section of the retainer ring body is quadrate. As the cross section of the retainer ring is polygon, the retainer ring body cannot deform easily, and the transformation quantity of the retainer ring body is smaller under the gear impact function of the clutch, so that the gear of the clutch can be effectively prevented from slipping out of the output shaft.
Description
Technical field
The utility model relates to the spacing collar on a kind of output shaft that is used for actuating motor.
Background technology
The cross section of the spacing collar of installing on the draw-in groove on the output shaft of actuating motor of the prior art is for circular; When opening actuating motor, the gear of the isolator of actuating motor can produce bump to above-mentioned spacing collar, because the cross section of spacing collar of the prior art is circular; Cause spacing collar to be easy to distortion; The deflection that under the bump of said gear, takes place is bigger, and gear might directly flatten spacing collar, and the distortion of this degree makes spacing collar lose spacing effect through regular meeting; Make gear cross spacing collar, skid off from output shaft.
The utility model content
The technical problem that the utility model solves provides the spacing collar on the output shaft that is used for actuating motor that a kind of gear that can effectively avoid isolator skids off from output shaft.
The utility model solves the technical scheme that its technical problem adopted: be used for the spacing collar on the output shaft of actuating motor, comprise the collar body, the cross section of said collar body is a polygon, and the said polygonal limit scope of counting is 4～8.
Further be: said polygonal limit number is 4.
Further be: said polygon is square.
The beneficial effect of the utility model is: because the cross section of collar body is a polygon; Make the collar body not yielding; Under the gear effect of impact of isolator, the deflection that this collar body takes place is less, can effectively avoid the gear of isolator to skid off from output shaft.
Description of drawings
Fig. 1 is equipped with the sketch map that cross section is polygonal collar body on the output shaft.
Be labeled as among the figure: 1-collar body, 2-cross section, 3-draw-in groove, 4-output shaft.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As shown in Figure 1, the spacing collar on the output shaft that is used for actuating motor of the utility model comprises collar body 1, and the cross section 2 of said collar body 1 is a polygon, and the said polygonal limit scope of counting is 4～8.The cross section 2 of above-mentioned collar body 1 can be quadrangle, pentagon, hexagon, heptagon or octagon.
During use; Above-mentioned collar body 1 is installed in the draw-in groove 3 of output shaft 4; When opening actuating motor, the gear of isolator can clash into this collar body 1, because the cross section 2 of collar body 1 is a polygon; So the deflection that this collar body produces under effect of impact is less, can effectively avoid gear to skid off from output shaft 4.
On the basis of the above, the cross section 2 of above-mentioned collar body 1 is preferably quadrangle, because of this collar body construction is simple, and is convenient to processing and use.Further be, the cross section 2 of above-mentioned collar body 1 is preferably square, and the deflection that under the gear effect of impact, takes place because of this collar body is very little.
Claims (3)
1. be used for the spacing collar on the output shaft of actuating motor, comprise collar body (1), it is characterized in that: the cross section (2) of said collar body (1) is a polygon, and the said polygonal limit scope of counting is 4～8.
2. the spacing collar on the output shaft that is used for actuating motor as claimed in claim 1, it is characterized in that: said polygonal limit number is 4.
3. the spacing collar on the output shaft that is used for actuating motor as claimed in claim 2 is characterized in that: said polygon is square.
