Figure 1 In the direction shown, the inner circumference of the left end is provided with a first internal transmission spline, which meshes with the first external transmission spline on the left end of the drive shaft, wherein the first internal transmission spline and the first external transmission spline are spiral splines. The spline tube is integrally sleeved on the drive shaft and can slide on the drive shaft. The outer circumference of the spline tube is divided into a first step surface 201, a second step surface 202, a third step surface 203, a fourth step surface 204 and a fifth step surface 205 from left to right. The first bearing 18 is arranged on the first step surface 201, and the second bearing 5 is arranged on the fifth step surface 205. The first bearing 18 and the second bearing 5 are used to support the entire one-way clutch. As shown in FIG. Figure 2 As shown, a plurality of inclined arcuate support surfaces 21 are evenly distributed on the third step surface 203, and the center of the circle corresponding to the arcuate support surface 21 deviates from the axis of the spline tube, and taking the direction shown in the figure as an example, the distance between the left end of the arcuate support surface 21 and the axis of the spline tube is smaller than the distance between the right end of the arcuate support surface 21 and the axis of the spline tube. Between each arcuate support surface 21 is a mounting surface, and a positioning groove is provided on the mounting surface 22, and the positioning protrusion of the retainer 13 is embedded in the positioning groove, which constrains the radial movement of the retainer 13 and the spline tube 2.

[0038] like Figure 3 and Figure 4As shown, the retainer 13 includes two mutually parallel first and second circular rings 1302 and 1303, with a connecting crossbeam 1304 in the middle, the connecting crossbeam 1304 is perpendicular to the first and second circular rings 1302 and 1303, and the bottom of the connecting crossbeam 1304 is arc-shaped. An accommodating cavity 1305 is formed between the adjacent connecting crossbeams 1304 and the first and second circular rings 1302 and 1303, and the roller 12 is arranged in the accommodating cavity 1305, and the accommodating cavity is rectangular as a whole. The upper side of the roller 12 is in close contact with the inner wall of the reduction gear ring 3, and the lower side of the roller 12 is in close contact with the arc-shaped supporting surface 21. Two mounting holes 1308 are symmetrically arranged on the connecting crossbeam 1304, and the mounting holes 1308 are used to install the support spring 11. Specifically, the two mounting holes 1308 are arranged on the side close to each other, and are specifically inclined from the outside to the inside toward the symmetry center, which is the same as the inclination direction of the two side pieces of the support spring 11. The connecting crossbeam 1304 is provided with roller limiting ridges 1306 on both sides close to the roller 12, specifically, 12 roller limiting ridges are provided at the bottom of both the left and right sides to prevent the 12 rollers from rolling and getting stuck. The bottom of the connecting crossbeam 1304 is provided with a positioning protrusion, which is embedded in the positioning groove of the spline tube. A limiting ridge is provided on the side of the second circular ring of the retaining frame close to the center of the circle, and the left side surface of the limiting ridge is against the right side surface of the third step surface, and the right side surface of the limiting ridge is against the left side surface of the sealing plate, which limits the relative movement of the retaining frame and the spline tube, so that the retaining frame and the inner hole of the reduction gear ring always maintain a certain gap, and the retaining frame and the inner hole of the reduction gear ring will not be damaged by friction, thereby improving the service life of the one-way clutch.

[0039] like Figure 5 As shown, the support spring 11 is composed of a fixed connection part and a support part. The fixed connection part is bent into a U-shaped cross-section. The two side plates are set at an acute angle with the bottom plate. The two side plates are clamped in two mounting holes on the connecting beam of the retainer, specifically the surfaces of the two mounting holes close to the symmetry center. The support spring is firmly controlled and fixed in the two mounting holes. In this way, the support spring will not move radially and centrifugally and be damaged by friction with the right inner hole of the reduction gear ring, and it can also ensure that the roller does not tilt, thereby greatly improving the service life of the one-way clutch. The support part is two support leaf springs, which are divided into upper and lower leaves, both of which are arc-shaped. The two support leaf springs are respectively against the roller 12 up and down.

[0040] The reduction gear ring 3 is a disc-like part, and its inner circumference is composed of two cylindrical surfaces of different sizes on the left and right. The inner diameter of the inner cylindrical surface on the left is smaller than that of the inner cylindrical surface on the right. The inner cylinder on the left is sleeved on the second step surface 202 of the spline tube; the outer circle is provided with a conical surface, an involute gear, a slot and a cylindrical surface from left to right in sequence. The right side of the reduction gear ring 3 is against the side of the support frame 16. The support frame 16 is provided with a rivet ring at one end facing the reduction gear ring. The rivet ring shrinks and rivets in the slot of the outer circle of the reduction gear ring 3, which restricts the radial and axial displacement of the support frame 16 and the reduction gear ring 3. The inner hole of the support frame 16 is sleeved on the outer cylindrical surface of the reduction gear ring 3, and the connecting end face is against the right end face of the 3 reduction gear rings. A bushing 15 is sleeved on the inner hole of the bushing 15. The inner hole of the bushing 15 is sleeved on the outer circle of the spline tube, and the left end face is against the right end face of the sealing plate 17, and the right end face is against the connecting end face of the inner hole of the support frame and the right inner hole. The side surface where the left outer circle and the middle outer circle of the sealing plate 17 connect is against the right side surface of the roller limiting ridge of the retaining frame 13, the right outer circle is sleeved in the inner hole of the cylindrical hole on the right side of the reduction gear ring, and the inner hole is sleeved on the outer circle of the spline tube.

[0041] The drive shaft 1 is a shaft-like part, and its outer circumference is cylindrical, and is specifically divided into a front section 101, a middle section 102, and a rear section 103, wherein the diameter of the front section 101 is larger than that of the middle section 102. The rear section 103 is provided with an empty knife groove 104 and a retaining ring groove, and the outer circumference of the front end is provided with a spiral spline meshing with the spiral spline of the inner hole at the left end of the spline tube 2, and the center of the drive shaft is provided with a blind hole 107 for placing the starter ejector pin, and the middle section 102 of the drive shaft is sleeved in the first spring and the smooth cylindrical inner hole at the right end of the spline tube, and the front and rear end surfaces of the first spring are respectively against the vertical outer end surface between the front section 101 and the middle section 102 of the drive shaft and the inner end surface of the spline tube, and the rear section 103 is provided with an involute straight spline and meshes with the involute straight spline on the inner circumference of the drive gear 8. The inner hole of the driving gear 8 is sequentially sleeved on the outer circumference of the baffle 6 and the second spring 7 from left to right, and the left and right end faces of the second spring 7 are respectively abutted against the right end face of the baffle 6 and the inner end face of the driving gear 8. A section of the outer circumference of the driving gear 8 facing away from the second bearing 5 is provided with an involute gear matching the engine ring gear, and a section of the outer circumference of the driving gear 8 close to the second bearing 5 is provided with a movable guide surface. The right end face of the driving gear 8 is provided with a locking ring 9 and a wire retaining ring 10 clamped in the inner ring of the locking ring 9. The wire retaining ring 10 is embedded in the retaining ring groove of the driving shaft. The wire retaining ring 10 rivets the locking ring 9 mounted on the driving shaft to prevent the driving gear 8 from falling out during operation.

[0042] The working principle of the present invention is: when the starter is powered on, the starter ejector pin moves forward to push the drive shaft 1 and the drive gear 8 forward, and the front gear of the drive gear 8 meshes with the engine gear ring gear. At this time, the main circuit is connected, the starter rotor rotates, and the engine gear ring is driven to rotate through the reduction gear ring 3, the roller 12, the spline tube 2, the drive shaft 1 and the drive gear 8, and the engine is started; when the starter is powered off, the starter ejector pin moves backward, and the drive shaft 1 and the drive gear 8 move backward, completing the entire process of starting and clutching. When the engine fails and the starting torque exceeds the maximum starting torque of the starter, the roller moves forward, the support spring cannot support the roller, the roller and the arc-shaped support surface slip, and the reduction gear ring 3 and the spline tube 2 slip.

[0043] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
