Abstract
The invention discloses a one-way clutch. The one-way clutch comprises a one-way clutch body, a hollow shaft and a spline shaft, wherein the one-way clutch body is fixedly connected with the hollow shaft; the hollow shaft is sleeved on the spline shaft; an inner spiral spline is arranged in the hollow shaft and is matched with an outer spiral spline which is arranged at one end of the spline shaft; the other end of the spline shaft extends out of the hollow shaft; and a drive gear is fixedly arranged on the hollow shaft. The one-way clutch has a simple structure and is easy to realize; the inner spiral spline of the hollow shaft and the outer spiral spline of the spline shaft are matched with each other to drive the spline shaft to rotate so as to drive the drive gear to rotate; and the spline shaft is shifted by a shifting fork to slide in a bearing in the axial direction, so that the drive gear is engaged with a flywheel ring gear of an engine to drive the flywheel ring gear of the engine to rotate, and thus the engine is started. The one-way clutch has a reasonable structure, and is high in transmission torque, stable in support and high in anti-bending capability.
Description
Technical field
The present invention relates to a kind of overrunning clutch, especially design the overrunning clutch that a kind of automobile starter is used.
Background technique
Along with the development of society and the progress of science and technology, automobile becomes the main means of transportation of people gradually, and this overrunning clutch demand that just makes automobile starter use is increasing; At present, its one-way element body of existing overrunning clutch and actuation gear are assembled into one, stir the one-way element body by shift fork and on splined shaft, slide, and there is following deficiency in this kind structure:
1, complex structure, difficulty of processing is big and work efficiency is low;
2, support is insecure, and bending resistance is poor;
3, mechanical transmission is not steady, and it is big to beat, and transmitting torque is little.
Summary of the invention
The objective of the invention is to provides a kind of overrunning clutch to the problems referred to above, and it has simple and reasonable for structure, and production and processing is convenient, and cost is low, and transmitting torque is big, the characteristics that working stability is reliable and bending resistance is strong.
The objective of the invention is to realize through following technological scheme:
A kind of overrunning clutch; Comprise one-way element body, hollow shaft and splined shaft, said one-way element body is fixedly connected with hollow shaft, and said hollow shaft sleeve is connected on the splined shaft; Be provided with internal thread spline in it; And match with the outer spiral spline of splined shaft one end setting, the other end of said splined shaft stretches out hollow shaft, and is set with actuation gear.
Further, said actuation gear is connected through key with splined shaft.
Further, said key is a spline.
Further, the two ends of said hollow shaft are provided with the bearing block, and are provided with bearing at bearing block place.
Further, said bearing is a rolling bearing.
Beneficial effect of the present invention does, said overrunning clutch is simple in structure, is easy to realize, the internal thread spline through hollow shaft cooperates the drive splined shaft to rotate with the outer spiral spline of splined shaft; Thereby drive the actuation gear rotation, and splined shaft stirred in bearing by shift fork and axially slide, make actuation gear and engine flywheel gear ring mesh; Thereby drive the rotation of engine flywheel gear ring, realize engine start, rational in infrastructure; Transmitting torque is big, supports firmly, and bending resistance is strong.
Description of drawings
Fig. 1 is the structural representation of a kind of overrunning clutch of the present invention.
Among the figure:
1, one-way element body; 2, hollow shaft; 3, bearing; 4, actuation gear; 5, splined shaft.
Embodiment
Further specify technological scheme of the present invention below in conjunction with accompanying drawing and through embodiment.
Please with reference to shown in Figure 1, Fig. 1 is the structural representation of a kind of overrunning clutch of the present invention; In present embodiment, a kind of overrunning clutch comprises one-way element body 1, hollow shaft 2 and splined shaft 5; Said one-way element body 1 is fixedly connected with hollow shaft 2, and the two ends of said hollow shaft 2 are provided with the bearing block, and is provided with bearing 3 at bearing block place; Said bearing 3 is a rolling bearing; Hollow shaft 2 is socketed on the splined shaft 5, is provided with internal thread spline in it, and matches with the outer spiral spline of splined shaft 5 one end settings; The other end of said splined shaft 5 stretches out hollow shaft 2, and is connected with actuation gear 4 through spline.
During work, one-way element body 1 is by driven by motor, and 2 rotations of drive hollow shaft; Because the outer spiral spline on the splined shaft 5 cooperates with the internal thread spline on the hollow shaft 2, therefore, hollow shaft 2 drives splined shaft 5 rotations again; Splined shaft 5 is stirred in bearing 3, to do by shift fork and is endwisely slipped in rotation, and the actuation gear 4 that is arranged on splined shaft 5 the other ends also moves with splined shaft 5; Make and drive actuation gear 4 and the engagement of engine flywheel gear ring the engine flywheel rotation, thereby realize engine start; After engine start, the actuating motor outage, actuation gear 4 rotating speeds descend, when the rotating speed of engine flywheel gear ring surpasses the rotating speed of actuation gear 4; Motor rotates through the anti-actuation gear 4 that drags of flywheel ring gear, applies yawning moment, at this moment; Under the effect of one-way element body 1, one-way element body and hollow shaft 2 unclamp, thereby make splined shaft 5 idle running; Meanwhile, the return spring in the starter switch is stirred through shift fork and is worked, and drives splined shaft 5 returns; Thereby drive actuation gear 4 returns, make actuation gear 4 and engine flywheel gear ring throw off, prevent that actuating motor from being exceeded the speed limit and the damage actuating motor by counter the dragging of engine flywheel gear ring.The present invention is simple and reasonable for structure, and production and processing is convenient, and cost is low, and transmitting torque is big, and working stability is reliable and bending resistance is strong.
Above embodiment has just set forth basic principle of the present invention and characteristic; The present invention is not limited by the foregoing description; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various variations and change, and these variations and change all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
