Description

Technical Field

[0001] This utility model relates to the field of mechanical processing and manufacturing technology, specifically a new type of cast belt pulley. Background Technology

[0002] Belt pulleys, belonging to the disc / hub category of parts, are generally relatively large in size. Their manufacturing processes primarily involve casting and forging (larger designs are typically cast using cast iron (due to its superior casting properties), rarely using cast steel (due to its poor casting properties); smaller designs can be forged from steel). Belt pulleys are mainly used for long-distance power transmission, such as in small diesel engines, agricultural vehicles, tractors, automobiles, mining machinery, machining equipment, textile machinery, packaging machinery, lathes, forging machines, power transmission in some low-horsepower motorcycles, power transmission in agricultural machinery, air compressors, reducers, speed reducers, generators, and cotton gins.

[0003] Existing pulleys are usually manufactured by machining cast or forged blanks. This is time-consuming, labor-intensive, wasteful of materials, and introduces errors in machining accuracy. Utility Model Content

[0004] The purpose of this invention is to provide a novel cast pulley.

[0005] A novel cast pulley includes a shaft head and a grooved pulley sleeved outside the shaft head. The shaft head and the grooved pulley are fixedly connected by a rib plate located in the middle of the shaft head and the grooved pulley. The outer wall of the grooved pulley has multiple belt grooves, and the center of the shaft head has a connecting inner hole.

[0006] Furthermore, a weight-reducing groove is provided between the shaft head, the grooved wheel, and the stiffening plate.

[0007] Furthermore, one end of the shaft head is flush with one end of the grooved wheel, and the other end of the shaft head is recessed into the other end of the grooved wheel.

[0008] Furthermore, the shaft head, connecting inner hole, stiffening plate, grooved wheel, belt groove and weight reduction groove are integrally formed by casting.

[0009] In summary, this utility model has the following beneficial effects:

[0010] The shaft head, connecting inner hole, stiffening plate, grooved wheel, belt groove, and weight-reducing groove of this invention are integrally cast, improving manufacturing precision. This invention eliminates the need for secondary machining, saving time and effort, reducing material waste, and lowering manufacturing costs. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] The following is in conjunction with the appendix Figure 1-3 The present invention will be further described as follows:

[0017] A novel cast pulley includes a shaft head 1 and a grooved pulley 4 sleeved on the outside of the shaft head 1. The shaft head 1 and the grooved pulley 4 are fixedly connected by a rib plate 3, which is located in the middle of the shaft head 1 and the grooved pulley 4. The outer wall of the grooved pulley 4 is provided with multiple belt grooves 5. A connecting inner hole 2 is provided at the center of the shaft head 1. A weight-reducing groove 6 is provided between the shaft head 1, the grooved pulley 4 and the rib plate 3. The shaft head 1, the connecting inner hole 2, the rib plate 3, the grooved pulley 4, the belt grooves 5 and the weight-reducing groove 6 are integrally formed by casting. One end of the shaft head 1 is flush with one end of the grooved pulley 4, and the other end of the shaft head 1 is recessed into the other end of the grooved pulley 4.

[0018] In this embodiment, the connecting inner hole 2 is used to connect the shaft head 1 to the drive shaft or transmission shaft. The common connection method is to pass the drive shaft or transmission shaft through the connecting inner hole 2 and then fix it with a fastening nut. Preferably, the end of the shaft head 1 that is flush with the grooved wheel 4 is located at the bottom of the drive shaft or transmission shaft to prevent the grooved wheel 4 from protruding outward and causing friction with components such as the motor; the fastening nut is located at the end of the shaft head 1 that is recessed with the grooved wheel 4. After the fastening nut is tightened, it can be completely or partially hidden, eliminating or reducing the outward protrusion of the fastening nut.

[0019] The weight reduction groove 6 reduces the overall weight of the pulley and reduces the load on the drive shaft or transmission shaft.

[0020] The diameter of the pulley 4 and the number of belt grooves 5 can be customized according to requirements.

[0021] The shaft head 1, connecting inner hole 2, rib plate 3, grooved wheel 4, belt groove 5, and weight reduction groove 6 are integrally cast, improving manufacturing precision. This utility model eliminates the need for secondary machining, saving time and effort, reducing material waste, and lowering manufacturing costs.

[0022] In summary, this utility model is not limited to the specific embodiments described above. Those skilled in the art can make various modifications and alterations without departing from the spirit and scope of this utility model. The scope of protection of this utility model should be determined by the claims of this utility model.
