Abstract
The utility model discloses an outer ring for a one-way device of an engine, which belongs to the technical field of automobile and motorcycle components. The outer ring comprises an outer ring main body, an inner hole, inner hole grooves, connecting holes and transverse straight holes. Three longitudinal inner hole grooves are uniformly arranged on the wall of the inner hole, three longitudinal connecting holes are uniformly distributed on the outer ring, three transverse straight holes which are through holes are uniformly arranged at the outer side of the outer ring, one end of the transverse straight holes is communicated to the outside of the outer ring, and the other ends of the transverse straight holes are communicated with one side of the inner hole grooves. Left and right steps are arranged at one side of the transverse straight holes communicating to the outside of the outer ring. The peripheral lines of the vertical sections of the left and right steps are oval, the left and right steps are symmetrical left and right, and the proportion of the oval semi-diameter of the peripheral lines of the left and right steps is 0.85. The outer ring has the following benefits: as the left and right steps are arranged at one side of the transverse straight holes communicating to the outside of the outer ring, the press-separating force is increased and a choke plug arranged in an inclined hole cannot easily fall off; moreover, the safety performance is improved and the maintenance cost is reduced.
Description
Technical field
The utility model relates to a kind of motor one-way element outer shroud, particularly relates to a kind of horizontal straight hole motor one-way element with the level outer shroud, belongs to automobile, motorcycle part technical field.
Background technique
Automobile, motorcycle are the most frequently used traffic tool of people, and motor one-way element outer shroud is one of most important parts in automobile, the motorcycle engine, also are a kind of easily worn parts.Shown in Fig. 1 (A), (B), the motor one-way element outer shroud that uses on present automobile, the motorcycle, comprise outer shroud main body, endoporus, endoporus groove, attachment hole and horizontal straight hole, in the inner hole wall, evenly be provided with 3 vertical endoporus grooves, be evenly distributed with 3 vertical attachment holes on the outer shroud, the outer shroud outside evenly is provided with 3 horizontal straight holes, laterally straight hole is a through hole, and an end leads to outside the outer shroud, and the other end communicates with a side of endoporus groove, because laterally straight hole does not have step, pressure-off power is less, and plug comes off easily, the damage outer shroud.
The model utility content
The purpose of this utility model is the defective at above-mentioned prior art, and a kind of motor one-way element outer shroud is provided.One-way element outer shroud strabismus hole changes step hole into by straight hole, increases pressure-off power, makes to improve Safety performance by the plug difficult drop-off that installs in the inclined hole, reduces maintenance cost.
To achieve these goals, the technological scheme that the utility model is taked is: a kind of motor one-way element outer shroud, comprise outer shroud main body, endoporus, endoporus groove, attachment hole and horizontal straight hole, in the inner hole wall, evenly be provided with 3 vertical endoporus grooves, be evenly distributed with 3 vertical attachment holes on the outer shroud, the outer shroud outside evenly is provided with 3 horizontal straight holes, laterally straight hole is a through hole, one end leads to outside the outer shroud, the other end communicates with a side of endoporus groove, and horizontal straight hole leads to the outer side of outer shroud and is provided with left and right step.
The outer contour of the vertical cross-section of described left and right step is oval, and the center of circle of the vertical cross-section of the center of circle of the outer contour ellipse of the vertical cross-section of left and right step and horizontal straight hole is the same center of circle.
The minor axis radius of the oval Vertical direction of the outer contour of described left and right step equates with the radius of horizontal straight hole, upper and lower 2 upper and lower ends that are cut in horizontal straight hole outward of the oval Vertical direction of the outer contour of left and right step.
The left and right symmetry of described left and right step.
The oval radius ratio of the outer contour of described left and right step is 0.8-0.9.
The oval radius ratio of the outer contour of described left and right step is 0.85.
Compared with prior art, the beneficial effects of the utility model are:
(1) laterally straight hole leads to the outer side of outer shroud and is provided with left and right step, has increased pressure-off power, makes the plug difficult drop-off that installs in the inclined hole;
(2) improve Safety performance, reduce maintenance cost.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
Shown in Fig. 2 (A), (B), (C), a kind of motor one-way element outer shroud, comprise outer shroud main body 1, endoporus 2, endoporus groove 3, attachment hole 4 and horizontal straight hole 5, in endoporus 2 walls, evenly be provided with 3 vertical endoporus grooves 3, be evenly distributed with 3 vertical attachment holes 4 on the outer shroud main body 1, outer shroud main body 1 outside evenly is provided with 3 horizontal straight holes 5, laterally straight hole 5 is a through hole, one end leads to outside the outer shroud main body 1, the other end communicates with a side of endoporus groove 3, and horizontal straight hole 5 leads to outer shroud main body 1 an outer side and is provided with left step 6 and right step 7.
The outer contour of the vertical cross-section of left side step 6 and right step 7 is oval, the center of circle of the vertical cross-section of the center of circle of the outer contour ellipse of the vertical cross-section of left side step 6 and right step 7 and horizontal straight hole 5 is the same center of circle, the minor axis radius of the oval Vertical direction of the outer contour of left side step 6 and right step 7 equates with the radius of horizontal straight hole 5, upper and lower 2 upper and lower ends that are cut in horizontal straight hole 5 outward of the oval Vertical direction of the outer contour of left side step 6 and right step 7, left side step 6 and right step 7 left and right symmetries, the oval radius ratio of the outer contour of left step 6 and right step 7 is 0.85.Laterally straight hole leads to the outer side of outer shroud and is provided with left and right step, has increased pressure-off power, makes the plug difficult drop-off that installs in the inclined hole; Improve Safety performance, reduce maintenance cost.
