Description

Technical Field

[0001] The utility model relates to the technical field of synchronous wheels, in particular to a pair-type concentric synchronous wheel. Background Art

[0002] Synchronous wheels are generally made of steel, aluminum alloy, cast iron, brass and other materials. The synchronous wheel transmission consists of an endless belt with equally spaced teeth on the inner surface and a pulley with corresponding teeth. During operation, the belt teeth mesh with the tooth grooves of the pulley to transmit motion and power. The synchronous wheel has the advantages of accurate transmission, constant transmission ratio, smooth transmission, high transmission efficiency, convenient maintenance, no need for lubrication, low maintenance cost, and a large speed ratio range. Therefore, synchronous wheel assemblies are widely used in new mechanical belt drives in various industries such as automation equipment, machine tools, textiles, printing, food packaging, wires and cables, instruments and meters, petrochemicals, tobacco, and communications.

[0003] The existing synchronous wheels are usually connected to the power generating device through the driving wheel, thereby driving the driven wheel to rotate. In addition, there is no unified setting for the transmission direction of the synchronous wheels, which results in that multiple groups of existing synchronous wheels cannot be operated at the same time. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a matching concentric synchronous wheel, which solves the problem that the transmission direction of the existing synchronous wheels is not uniformly set, resulting in the inability of multiple groups of existing synchronous wheels to operate simultaneously.

[0005] The technical solution adopted by the utility model is: comprising a first synchronous wheel and a second synchronous wheel; the first synchronous wheel comprises a first convex ring, a first bearing arranged in the first convex ring, a first limit platform connected to the first bearing and limiting the first bearing, and a first groove arranged on the first limit platform; the second synchronous wheel comprises a second convex ring, a second bearing arranged in the second convex ring, a second limit platform connected to the second bearing and limiting the second bearing, and a second groove arranged on the second limit platform; the first convex ring and the second groove cooperate with each other and are limited by the second limit step, so that the first synchronous wheel and the second synchronous wheel cooperate with each other to perform synchronous transmission.

[0006] A further improvement to the above scheme is that two groups of symmetrically arranged first limit baffles are provided on the outer side of the first synchronous wheel, a plurality of first limit blocks are provided between the two groups of first limit baffles, and the plurality of first limit blocks are connected and arranged along the first limit baffles to form a first limit groove.

[0007] A further improvement to the above solution is that the first limiting block and the first limiting groove are continuously arranged on the first limiting baffle plate to form a first positioning end, and the first positioning end performs multi-directional positioning on the first synchronous wheel.

[0008] A further improvement to the above solution is that the first convex ring is a conical convex ring.

[0009] A further improvement to the above solution is that a first fixing groove is provided between the first bearing and the first limiting step, and the first fixing groove is used to fix the first bearing.

[0010] A further improvement to the above scheme is that two groups of symmetrically arranged second limit baffles are provided on the outer side of the second synchronous wheel, a plurality of second limit blocks are provided between the two groups of second limit baffles, and the plurality of second limit blocks are connected and arranged along the second limit baffles to form a second limit groove.

[0011] A further improvement to the above solution is that the second limiting block and the second limiting groove are continuously arranged on the second limiting baffle plate to form a second positioning end, and the second positioning end performs multi-directional positioning on the second synchronous wheel.

[0012] A further improvement to the above solution is that the second convex ring is a conical convex ring.

[0013] A further improvement to the above solution is that: a second fixing groove is provided between the second bearing and the second limiting step, and the second fixing groove is used to fix the first bearing.

[0014] A further improvement to the above scheme is that the first convex ring and the second groove cooperate with each other and are limited by the second limiting step, so that the first synchronous wheel and the second synchronous wheel are synchronized. Conversely, when the second convex ring and the first groove cooperate with each other and are limited by the first limiting step, the first synchronous wheel and the second synchronous wheel can be synchronized in the opposite direction.

[0015] The beneficial effects of the utility model are:

[0016] Compared with the existing synchronous wheels, the utility model cooperates with the first convex ring and the second groove and limits the first synchronous wheel and the second synchronous wheel through the second limiting step, so that the first synchronous wheel and the second synchronous wheel can perform forward synchronous transmission, and limit the first synchronous wheel and the second synchronous wheel through the second limiting step, thereby improving the transmission stability of the first synchronous wheel and the second synchronous wheel, and the first synchronous wheel and the second synchronous wheel are provided with a first limiting baffle and a second baffle to facilitate the first synchronous wheel and the second synchronous wheel to limit the synchronous transmission during the synchronous transmission, and through the positioning end formed by the limiting block and the limiting groove in the first limiting baffle and the second limiting baffle, the first synchronous wheel and the second synchronous wheel can perform multi-directional positioning transmission, thereby improving the practicality of the synchronous transmission of the first synchronous wheel and the second synchronous wheel. On the other hand, the second convex ring cooperates with the first groove to perform reverse transmission on the first synchronous wheel and the second synchronous wheel, and limit the first limiting step, thereby improving the transmission stability and transmission accuracy, and the utility model has wide practicality and good application prospects.
