Abstract
A synchronous belt wheel provided with a flange comprises a synchronous pulley main body and retainer rings, wherein, the synchronous pulley main body is provided with a synchronous gear, and the retainer rings are positioned on both sides of the synchronous pulley main body; shaft tips which are coaxial with the synchronous pulley main body are formed on both sides of the synchronous pulley main body; holes are formed at the centers of the retainer rings; the shaft tips are sheathed with the holes; a plurality of sunken teeth are formed on the outer edges of the outer end surfaces of the shaft tips in a punching manner; and the retainer rings are fixed to the synchronous pulley main body by the sunken teeth. The synchronous belt wheel provided with a flange is manufactured by respectively manufacturing the synchronous pulley main body and the retainer rings, wherein, the synchronous pulley main body can be manufactured by adopting a conventional synchronous pulley technology, such as gear milling, gear shaping and the like, and the advantages of high efficiency and high accuracy can be achieved. The retainer rings can be manufactured by adopting a punching technology, and has the advantages of good accuracy, high efficiency and low cost; after the synchronous pulley main body and the retainer rings are assembled, the sunken teeth are formed on the outer edges of the outer end surfaces of the shaft tips of the synchronous pulley main body by adopting the punching technology, and the synchronous pulley main body and the retainer rings are assembled together effectively, thereby being very firm.
Description
Technical field
The utility model relates to a kind of synchronous pulley, particularly a kind of synchronous pulley with rib.
Background technique
Synchronous pulley is widely used as parts commonly used in the existing machinery transmission device.Synchronous pulley is divided into two kinds at present, and a kind of synchronous pulley and gear structure are somewhat similar, and another kind is the synchronous pulley with rib.Synchronous pulley with rib has the function that prevents that driving belt from coming off, and is widely used in the mechanical transmission.But this synchronous pulley with rib is processed the comparison difficulty, and present method normally adopts the method for casting to process.Adopt the synchronous pulley of casting method processing to have the processing cost height, the problem that precision is low is to perplex mechanical industry technology personnel a great problem always.Also have the employing milling machine to process for synchronous pulley, but efficient is low with rib.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of synchronous pulley with rib, is not easy to produce cost of production height, inefficient problem to solve existing synchronous pulley with rib.
Technical problem to be solved in the utility model can be achieved through the following technical solutions:
A kind of synchronous pulley with rib, comprise synchronous pulley main body with synchronous tooth and the back-up ring that is positioned at synchronous pulley main body both sides, it is characterized in that, the both sides of described synchronous pulley main body have the axle head coaxial with the synchronous pulley main body, described back-up ring center drilling, be enclosed within on the described axle head, dashing in the exterior edge face of described axle head outer rim has some teeth that collapse, and described some teeth that collapse are fixed in back-up ring on the described synchronous pulley main body.
Center in described synchronous pulley main body offers axis hole.Can also in axis hole, be provided with keyway, so that be connected with the transmission axle key.
Described some teeth that collapses are distributed on the exterior edge face of described axle head.
The synchronous pulley that the utility model will have rib is divided into synchronizing wheel main body and two manufacturings of back-up ring, and wherein the synchronous pulley main body can adopt conventional synchronous pulley, as technology manufacturings such as mill teeth, gear shapings, has the efficient height, advantage of high precision.Back-up ring can adopt the stamping process manufacturing, have that precision is good, efficient is high, the advantage that cost is low, after synchronous pulley main body and back-up ring assemble, adopt stamping process to go out some teeth that collapse in the exterior edge face of the axle head of synchronous pulley main body outer rim, effectively synchronous pulley main body and back-up ring are fitted together, very firm.

Fig. 2 is the utility model back-up ring structural representation.
Fig. 3 is the structural representation that the utlity model has the synchronous pulley of rib.
Fig. 4 is the left view of Fig. 3.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
With reference to Fig. 1, synchronous pulley main body 1 outer ring is provided with synchronous tooth 11, and both sides are processed with the diameter axle head 12,13 littler than root diameter, axle head 12,13 same diameters, coaxial line; Have axis hole 14 at the center of synchronous pulley main body, in axis hole 14, can also be provided with keyway 15, so that be connected with the transmission axle key.The synchronous tooth 11 of synchronous pulley main body 1 can adopt mill teeth or the manufacturing of gear shaping technology, and the axle head 12,13 of both sides adopts Vehicle Processing technology to process, and has the advantage that precision is good, efficient is high.
With reference to Fig. 2, the thickness of two back-up rings 2 is 1-1.5mm, the center drilling 21 of back-up ring 2, axle head 12,13 transition fit of hole 21 and synchronous pulley main body 1 both sides.Back-up ring 2 directly adopts the stamping process manufacturing, has the advantage that precision is good, efficient is high.
Referring to Fig. 3 and Fig. 4, two back-up rings 2 are snapped onto on the axle head 12,13 of synchronous pulley main body 1 both sides, adopt rolling technology then, go out some teeth 16,17 that collapse in the exterior edge face outer rim of axle head 12,13, some like this teeth 16,17 that collapse are fixed in two back-up rings 2 on the synchronous pulley main body 1.
After whole synchronous pulley assembles, carry out zinc-plated processing, get rusty preventing.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
