Abstract

The utility model provides a synchronizer gear ring belongs to mechanical technical field. It has solved the current synchronizer gear ring scheduling problem that easily weares and teares. This synchronizer gear ring is including being annular body, and the outer peripheral face of body has transition tooth, and the inner peripheral surface of body is conical surface form, and seted up a plurality of spout to the body and this side circumference evenly distributed has the radial convex lug of a plurality of in inner peripheral surface collar extension diameter little side, and the base width of lug is greater than the topside width of lug, and the radial cross section of lug is isosceles trapezoid, and the hypotenuse of lug is 3~10 rather than high contained angle a. The utility model has the advantages of the atress is steady, wearing and tearing are even.

Description

A kind of synchro converter ring

Technical field

This utility model belongs to field of mechanical technique, is related to a kind of lock unit, more particularly to a kind of synchro converter ring.

Background technology

Applicant devises a kind of combined synchronizer and has declared patent [application number：201520920137.9；Authorize Notification number：CN205136417U], it includes power shift gear, and power shift gear is axially arranged with gear ring, and power shift gear both sides are equipped with Cone tooth, is provided with synchronous ring and the conical ring for contacting synchronous ring inner peripheral surface, power shift gear and cone tooth between cone tooth and power shift gear Between be provided with the ring gear for being placed on synchronous ring outer peripheral face, the outer peripheral face of ring gear has transition teeth, and ring gear inner peripheral surface is near cone tooth Collar extension causes the inner peripheral surface of ring gear in conical surface shape with diameter greater than inner side collar extension diameter, and ring gear is offered towards the sidepiece of power shift gear Chute, power shift gear is provided with the slide block in chute, and the width of chute is more than the width of slide block.

Ring gear in combinations thereof type synchronizer is rotated by synchronous annulus is dynamic, and ring gear turns over certain angle so that gear ring Internal tooth snap past the transition teeth of ring gear, then snap in the teeth of cone tooth, each teeth will not clashing and breaking, the setting of ring gear enhances together Step performance, above-mentioned ring gear is circumferentially evenly distributed with the projection of some pieces of radially protrudings in the sidepiece of chute homonymy, and projection plays card Position effect, applicant have discovered that the two sides of projection are to be arranged symmetrically and each parallel to the median plane of projection, so rotating During screens, the seamed edge of side contact first gear ring against place, be line linear contact lay, the stress of such projection is not steady enough, Abrasion is uneven, using can cause screens effect on driving birds is not good after a period of time.

The content of the invention

The purpose of this utility model is for the above-mentioned problems in the prior art, there is provided a kind of stress is steady, mill Damage uniform synchro converter ring.

The purpose of this utility model can be realized by following technical proposal：A kind of synchro converter ring, including it is annular in shape Body, the outer peripheral face of described body has transition teeth, and the inner peripheral surface of body is in conical surface shape, and described body is in inner circumferential face ring The little side of mouth diameter offers several chutes and this side is circumferentially evenly distributed with the projection of several radially protrudings, and it is special Levy and be, the base width of described projection is more than the top margin width of projection, and the radial section of described projection is isosceles trapezoid, The angle a that the hypotenuse of described projection is high with it is 3 °~10 °.

By changing projection shape, during screens is rotated, the hypotenuse of projection side contacts gear ring to this synchro converter ring Against place, realize contact of the face with face, the hypotenuse of projection opposite side is similarly contact of the face with face, such projection during reset Two hypotenuse even wearings, projection stress is steady, and screens effect is good.

In a kind of above-mentioned synchro converter ring, the inner peripheral surface of described body offers the helicla flute with closely-pitched.This Sample body is with after the contact of synchronous ring, and helicla flute can destroy oil film, increased the friction between body inner peripheral surface and synchronous ring, synchronous Effect is good.

In a kind of above-mentioned synchro converter ring, it is recessed that the inner peripheral surface of described body is circumferentially evenly distributed with several Interval trough.Interval trough avoids oil film from adhering to, it is ensured that the synchronous effect of body and synchronous ring.

Compared with prior art, this synchro converter ring realizes contact of the face with face, projection two by changing projection shape Hypotenuse even wearing, projection stress is steady, and screens effect is good, and synchronous effect is good.

Specific embodiment

The following is specific embodiment of the utility model and combine accompanying drawing, further is made to the technical solution of the utility model Description, but this utility model is not limited to these embodiments.

As shown in figure 1, this synchro converter ring includes body 1 annular in shape, the outer peripheral face of body 1 has transition teeth 2, this The inner peripheral surface of body 1 is in conical surface shape, and body 1 offers three chutes 3 and this side circumference in the little side of inner peripheral surface collar extension diameter The projection 4 of three radially protrudings is evenly distributed with, the base width of projection 4 is more than the top margin width of projection 4, the radial direction of projection 4 Section is isosceles trapezoid, and the angle a that the hypotenuse of projection 4 is high with it is 3 °~10 °, and base width exceeds top margin according to practical situation Width 40-100 silks, angle a is 10 ° in the present embodiment.

This synchro converter ring is by the change shape of projection 4, during screens is rotated, the hypotenuse Contact Tooth of the side of projection 4 Circle against place, realize contact of the face with face, the hypotenuse of the opposite side of projection 4 is similarly contact of the face with face during reset, so 4 liang of hypotenuse even wearings of projection, the stress of projection 4 is steady, and screens effect is good.

Further describe in detail, in order to ensure synchronous effect, as shown in Fig. 2 the inner peripheral surface of body 1 offers the spiral shell with closely-pitched Spin slot 5, the inner peripheral surface of body 1 is circumferentially evenly distributed with six recessed interval troughs 6.

Specific embodiment described herein is only explanation for example to this utility model spirit.This utility model institute Category those skilled in the art can make various modifications to described specific embodiment or supplement or using similar Mode substitute, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
