Description

Field of the invention

[0001] The present utility model relates to the relevant technical area of ​​the pulley, in particular an integrated pulley. State of the art

[0002] Pulleys belong to the category of hub components and are generally relatively large in size. Casting and forging are the main manufacturing processes used. For a large-sized pulley, the pulley is designed to be manufactured by casting. The material used is generally cast iron, which has better casting properties. Cast steel is rarely used due to its poor casting properties. For a small-sized pulley, the pulley is designed to be manufactured by forging. Steel is used as the material.The belt pulley is mainly used for long-distance transmission of driving forces, such as an output of the driving forces of a small diesel engine, agricultural vehicles, tractors, automobiles, mining machinery, mechanical processing equipment, textile machinery, packaging machinery, lathes, forging beds, transmission of the driving forces of some small motorcycles, transmission of the driving forces of agricultural machinery, air compressors, reduction gears, generators, stamping machines, etc.

[0003] However, when using integrated pulleys, the synchronous wheels currently available on the market for use with center-mounted electric motors are all designed in a separate structure. That is, the synchronous wheels are combined with various claws and protective discs by interlocking or riveting, and then the components are combined for insertion into the center shaft of the center-mounted electric motor. Currently, many types of related parts are produced, resulting in complex processing technology, long production cycles, difficult safety control, low efficiency, and high costs. Therefore, it is necessary to propose an integrated pulley. Object of the invention

[0005] In order to achieve the above-mentioned object, the present utility model provides the following technical solution: an integrated pulley comprising a protective disk, wherein a toothed disk is provided on an inner periphery of the protective disk, and wherein a disk claw is welded to an inner periphery of the toothed disk, and wherein a crank is provided on one side of an outer wall of the protective disk, and wherein a lateral locking screw is provided continuously on one side of the crank.

[0006] Preferably, the toothed disc and the disc claw are integrally formed with the protective disc, with the centerline of the toothed disc coinciding with the centerline of the protective disc. Preferably, the crank is connected to the housing by means of a thread via the lateral locking screw, with the lateral locking screw being movably connected to the crank. Preferably, the housing is connected to another side of the protective disc, and a protective cover is provided on another side of the housing.

[0007] Preferably, large recesses are provided on both sides of the outer wall of the toothed disc, wherein the outer wall of the toothed disc is provided with a V-shaped inclination on both sides.

[0008] Preferably, internal teeth are provided on an inner wall surface of the protective disc, which are formed in a “sawtooth structure”.

[0009] Compared with the current state of the art, this utility model has the following advantages: The integrated design cleverly combines three parts, forming a one-piece synchronous wheel with multiple functions, effectively reducing various complicated processes, significantly reducing production costs, and achieving high production efficiency. Product replacement during after-sales service is made easier and faster. The design of the timing pulley combines a large recess on both sides with a V-shaped slope on both sides, effectively solving the problem of difficult fine sand discharge during operation. This increases the service life of the entire belt transmission.The engineered stop edge of this integrated pulley features dual guides, effectively solving the problem of smoothly inserting the belt into the groove during operation and preventing belt slippage, tooth jump, and other problems. This integrated pulley complies with the relevant ISO protection standards. The internal tooth profile of this design can be freely switched according to the centerline tooth profile of various center-mounted electric motors, increasing compatibility and expanding the application range.
