Abstract
The utility model discloses an engine shaft used retainer ring, which includes a retainer ring body and an opening, and is characterized in that two identical dents are formed on the end faces of the two ends of the opening. The engine shaft used retainer has the advantages of simple structure, easy processing and basically no increase in cost; on occasions where the external diameter of the retainer ring is subject to great restrictions, the retainer ring can still be mounted or dismounted with a pair of retainer pliers, so that the use is convenient, the mounting or dismounting efficiency can be effectively provided, and maximum results can be achieved with little effort.
Description
Technical field
The utility model relates to a kind of appurtenances of engine shaft, especially the shaft block ring of engine shaft.
Background technique
All need in the rotating shaft of motor to position, fix etc. with the parts on the back-up ring countershaft, as the appurtenances of engine shaft, at the parts on the fixed rotating shaft, prevent that it from coming off in high speed rotating, tool has certain effect.Shaft block ring in the motorcycle of prior art or other power plant all is a standard generally, for the ease of installing, at the opening end of back-up ring, is provided with two apertures on the left and right both sides of opening, and its radial dimension is local bigger than other; During installation, circlip pliers inserts in this two aperture, is convenient to install.Because the opening end size of this shaft block ring is bigger, so this shaft block ring can only be applicable to its external diameter and not be subjected to the situation of tighter restriction, if the external diameter of shaft block ring is very limited, that is to say in all conditional use occasion of the interior external diameter of back-up ring, at this moment back-up ring can only be designed to the annulus with opening, be similar to the rectangle piston ring a little, but, aperture can not be set basically insert for circlip pliers in the opening both sides of back-up ring; So this back-up ring can't use circlip pliers when installation and removal, dismounting by hand is very inconvenient, and efficient is low.
Summary of the invention
The utility model provides a kind of shaft block ring at the above-mentioned deficiency of prior art shaft block ring; When the external diameter of back-up ring is very limited, still can use circlip pliers, easy disassembly, thus raise labour efficiency.
The technical solution of the utility model: the motor shaft block ring, comprise back-up ring body and opening, it is characterized in that: on the end face at opening two ends, inside recess is set;
Further feature is: two inside recesses that are arranged on the opening two ends are identical; Inside recess is a roundlet arc pit; The radius of arc of inside recess is 0.75mm～1mm, dark 0.3mm～0.55mm.
Shaft block ring of the present utility model with respect to prior art, has following characteristics:
1, simple in structure, easy processing; Substantially do not increase its cost;
2, the use occasion that is very limited at the external diameter of back-up ring still can be used circlip pliers, carries out installation or removal with circlip pliers, and is easy to use;
3, can effectively improve installation or removal efficient, reach the effect of getting twice the result with half the effort.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the back-up ring structural representation of prior art;
Fig. 2 is the utility model shaft block ring structural representation;
Fig. 3 is the sectional view of Fig. 2;
Fig. 4 is the utility model shaft block ring use occasion schematic representation.
Embodiment
In Fig. 1,1 back-up ring, 2-opening, 3-aperture;
The back-up ring of prior art shown in Figure 1 comprises back-up ring 1, and back-up ring 1 is provided with opening 2, and the left and right both sides at opening 2 are provided with aperture 3; Radial dimension around the aperture 3 is local bigger than other; During installation, circlip pliers inserts in this two aperture 3, is convenient to install.As prior art, be not further introduced at this.
In Fig. 2,3,4,4-back-up ring body, 5-opening, 6-inside recess, 7-rotating shaft, 8-gear;
The utility model shaft block ring comprises back-up ring body 4 and opening 5, and back-up ring body 4 is toroidals, back-up ring body 4 right and wrong closures, be provided with opening 5; On back-up ring body 4, the end face at opening 5 two ends is provided with inside recess 6, and inside recess 6 the bests are roundlet arc pits; According to the width of back-up ring body 4 annulus, the radius of arc of inside recess 6 can be 0.75mm～1mm, the dark 0.3mm～0.55mm of pit.As optimum structure of the present utility model, two inside recesses 6 that are arranged on opening 5 two ends are identical, measure-alike, its position symmetry.
The utility model shaft block ring use occasion shown in Figure 4 is that the external diameter of back-up ring body 4 is subjected to strict restriction, and the size that does not allow its opening 5 two ends is greater than other positions.Gear 8 is set in rotating shaft 7, and the inboard that is connected with rotating shaft 7 at gear 8 is provided with the utility model back-up ring.This two inside recesses 6 have been arranged, and after inserted at the tip of circlip pliers, circlip pliers just can slippage, during the dismounting back-up ring, strut back-up ring with hand fully just need not resembling before the improvement, effort and efficient are very low, just can be easy to dismounting with circlip pliers, reach the effect of getting twice the result with half the effort.
