Description

Technical Field

[0001] This utility model relates to the field of rollers, and specifically to a roller with a toothed shape. Background Technology

[0002] Existing welded sprockets use chains to transmit power, which generates significant noise during operation. Furthermore, because grease is applied to the chain and sprockets, a large amount of dust and impurities accumulate over time, making the conveyor belt dirty and potentially contaminating the conveyed items. To reduce noise and avoid grease use, synchronous belt drives are preferable. However, using synchronous belts requires machining teeth on one end of the rollers. Since the rollers are relatively long, there is insufficient space on gear hobbing machines to accommodate them. Therefore, a toothed roller is urgently needed to address these issues. Utility Model Content

[0003] The technical problem this invention aims to solve is that existing welded sprockets use chains to transmit power, which generates significant noise during operation. Furthermore, because grease is applied to the chain and sprockets, a large amount of dust and impurities accumulate over time, making the conveyor belt dirty and even contaminating the conveyed items. To reduce noise and avoid grease use, synchronous belt drives are preferable. However, with synchronous belts, one end of the roller must be machined with teeth. Since rollers are generally long, there is insufficient space on gear hobbing machines. This invention provides a toothed roller by separately machining the roller body, toothed end, and cylindrical end, then welding them together. After finishing on a lathe and electroplating, the welding marks are almost invisible, perfectly solving the problem of machining the toothed shape of the roller and effectively addressing the difficulty of machining teeth on long rollers. This successfully upgrades the roller from chain drive to synchronous belt drive without significantly increasing costs, while ensuring product quality. The structure is simple and easy to use, thus overcoming the shortcomings of existing technologies.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A toothed roller includes a cylindrical body, which is a conical cylindrical body. One end of the cylindrical body is fitted with a toothed end, and the other end is fitted with a cylindrical end. The other end of the toothed end is a serrated portion. The three parts are processed separately and then assembled. The toothed end is processed with a gear hobbing machine. A roller shaft is inserted into the cylinder, and its two ends are connected to the toothed end and the inner wall of the cylindrical end through bearings. The roller shaft is used to support the rotation of the cylinder.

[0005] The aforementioned toothed roller, wherein both the toothed end and the cylindrical end are welded to the cylinder body.

[0006] The aforementioned toothed roller has slots at both ends of the cylinder body for inserting the toothed end and the cylindrical end.

[0007] In the aforementioned toothed roller, the toothed end and the cylindrical end are connected by welding at the joint after being inserted into the slot.

[0008] In the aforementioned toothed roller, the toothed end and the cylindrical end inserted into the groove are a connecting block, and a connecting ring with the same diameter as the cylinder is provided around the connecting block. The connecting ring is connected to the cylinder by welding.

[0009] In the aforementioned toothed roller, the connecting ring has an angled annular opening.

[0010] In the aforementioned toothed roller, the weld between the connecting ring and the cylinder body is coated with an electroplated layer.

[0011] The aforementioned toothed roller, wherein the serrations of the serrated portion are equally spaced.

[0012] The toothed roller described above has an electroplated layer at the weld joint between the toothed end, the cylindrical end, and the cylinder body. The joint can be filled by a rotary welding machine, making the three parts a whole.

[0013] The aforementioned toothed roller has connecting parts protruding from the cylinder body at both ends of the roller shaft for easy connection and fixation. The connecting parts may have connecting grooves at their ends for easy connection and can be applied to different mounting components.

[0014] When a toothed roller is used to transmit power to a sprocket, the noise generated is very small, no power grease is required for lubrication, and it can be used for a long time, effectively reducing the cost of use.

[0015] The technical solution provided by this utility model, which offers a toothed roller, has the following technical advantages: The roller is manufactured separately from the body, toothed end, and cylindrical end, and then welded together. After precision machining on a lathe and electroplating, the welding marks are almost invisible. This perfectly solves the problem of machining the tooth shape of the roller and effectively solves the problem of machining the tooth shape of long rollers. It successfully upgrades the roller from chain drive to synchronous belt drive without increasing the cost too much, and ensures the quality of the product. The structure is simple and easy to use.

During welding, the toothed ends 200 are inserted into the slot at one end of the cylinder 100 and welded. After welding, the contact surfaces of the toothed ends 200 and the cylinder 100 are welded together and then electroplated. The cylindrical ends 300 are inserted into the slot at the other end of the cylinder 100 and welded. After welding, the contact surfaces of the cylindrical ends 300 and the cylinder 100 are welded together and then electroplated.

[0028] The process involves using a rotary welding machine to fill the seams and integrate the three parts into a single unit. The welded areas are then electroplated, resulting in a finished product where the welding marks are almost invisible.
