Description

TECHNICAL FIELD

[0001] The application relates to the technical field of pulleys, in particular to a wear-resistant pulley. BACKGROUND

[0002] The pulley belongs to a hub part, is generally relatively large in size, and is mainly manufactured through casting or forging, and is mainly used for long-distance power transmission, for example, power output of a small diesel engine, an agricultural vehicle, a tractor, an automobile, a mine machine, a machining device, a textile machine, a packaging machine, a lathe, a forging machine, power transmission of some small-motorcycle, power transmission of an agricultural machine, an air compressor, a speed reducer, a speed reducer machine, a generator, a roller, and the like.

[0003] During operation, the pulley generates a large amount of heat, and if the heat cannot be dissipated in time, the temperature of the pulley is increased, the high temperature not only accelerates oxidation and aging of the material of the pulley, reduces the mechanical properties and wear resistance of the pulley, but also changes the friction coefficient between the belt and the pulley, further aggravates the wear, and even can cause serious problems such as softening and rupture of the belt.

[0004] The existing pulley also considers the heat dissipation problem in the design, and adopts some simple heat dissipation structures, for example, a fan blade is added to the pulley, but the existing heat dissipation structure lacks effective collaborative design with the overall structure of the pulley, and the influence of the heat dissipation structure on the strength and rigidity of the pulley is not fully considered, so that while the heat dissipation performance is improved, the other performances of the pulley can be adversely affected, and in order to solve the above problems, the application provides a wear-resistant pulley.

[0005] The above information disclosed in the background of the application is only used to increase the understanding of the background of the application, and therefore, can include prior art known by those skilled in the art. CONTENT OF THE UTILITY MODEL

[0006] In order to solve the above problems, the application provides a wear-resistant pulley.

[0007] The wear-resistant pulley provided by the application adopts the following technical scheme:

[0008] The wear-resistant pulley comprises a pulley body, fixed grooves are formed on both sides of the pulley body, reinforcing plates are fixed in the two fixed grooves, a plurality of heat dissipation fins are fixed at equal intervals on both sides of the reinforcing plates, the plurality of heat dissipation fins are distributed in an axisymmetric manner, and a gap exists between the heat dissipation fins on the inner side of the reinforcing plate and the fixed groove.

[0009] Preferably, the plurality of heat dissipation fins are in an arc shape.

[0010] Preferably, the length of the fins gradually increases from the outer side to the inner side of the reinforcing plate.

[0011] Preferably, an axle hole is formed in the pulley body for the axle to pass through.

[0012] Preferably, a key slot is formed in the pulley body for the key to be inserted into.

[0013] Preferably, an insertion hole is formed in the reinforcing plate for the axle to pass through.

[0014] In summary, the present application has the following beneficial technical effects:

[0015] 1. By equidistantly fixing multiple fins on both sides of the reinforcing plate fixed in the slots on both sides of the pulley body, and by symmetrically distributing the multiple fins, the fins can be evenly distributed around the pulley, effectively increasing the heat dissipation area. When the pulley is running, air can flow more smoothly over the surface of the fins, accelerating heat dissipation and effectively reducing the operating temperature of the pulley. Compared with related technologies, the present application can more fully exchange heat with the surrounding air, has higher heat dissipation efficiency, and can better cope with the heat generated under high load and high speed operating conditions, avoiding problems such as performance degradation of the pulley material and softening of the belt due to excessive temperature.

[0016] 2. By forming a fixing groove on both sides of the pulley body and fixing the reinforcing plate, the overall strength and rigidity of the pulley body are enhanced. The reinforcing plate can withstand the large load and stress generated during belt transmission, effectively preventing the pulley body from deforming or being damaged due to stress. Compared with related technologies, the reinforcing plate not only provides a mounting base for the fins, but also plays a structural strengthening role, ensuring that the pulley maintains a stable shape and performance during operation and prolonging the service life of the pulley.

[0017] 3. By setting the reinforcing plate and the fins, compared with related technologies, the overall strength and rigidity of the pulley are effectively enhanced, making the pulley more stable during operation, reducing the relative sliding and vibration between the belt and the pulley, and thus reducing wear caused by friction and impact.

[0022] The following will be described in detail in combination with the accompanying Figs. 1-3 The application is further described in detail.

[0023] The application discloses a wear-resistant pulley. Referring to Figs. 1-3 A wear-resistant pulley, comprising a pulley body 1, both sides of the pulley body 1 are provided with fixing grooves 9, reinforcing plates 6 are fixed in the two fixing grooves 9, a plurality of fins 8 are fixed at equal intervals on both sides of the reinforcing plates 6, and the plurality of fins 8 are distributed in axial symmetry, so that the fins 8 can be evenly distributed around the pulley body 1, effectively increasing the heat dissipation area. When the pulley body 1 operates, air can flow more smoothly through the surface of the fins 8, accelerating heat dissipation, effectively reducing the working temperature of the pulley body 1, and enabling more sufficient heat exchange with the surrounding air, higher heat dissipation efficiency, better coping with heat generated under high load and high-speed operating conditions, avoiding problems such as performance degradation of the pulley body 1 material and belt softening caused by excessively high temperature. There is a gap between the fins 8 inside the reinforcing plate 6 and the fixing groove 9, providing a smoother channel for air flow. During the rotation of the pulley body 1, air can enter the fin 8 area through the gap, forming good air circulation and further enhancing the heat dissipation effect.

[0024] It should be noted that the reinforcing plate 6 not only plays a structural reinforcing role itself, but also provides a stable mounting position for the fin 8, so that the fin 8 can be firmly fixed on the reinforcing plate 6, ensuring the stability and reliability of the heat dissipation structure, so that it can normally play the heat dissipation function.

[0025] Referring to Fig. 2 The plurality of fins 8 are arc-shaped. When the pulley body 1 rotates, air will flow along the arc-shaped surface of the fin 8, forming a more effective air flow path and further improving the heat dissipation efficiency. At the same time, the arc-shaped design can also reduce the vortex and turbulence of air flow, reducing energy loss.

[0026] Referring to Fig. 2 The length of the fin 8 gradually increases from the outside to the inside of the reinforcing plate 6, so that the heat dissipation demand at different positions can be optimized, the utilization rate of heat dissipation resources is improved, and effective heat dissipation can be ensured for each part of the pulley body 1. At the same time, the longer fin 8 can provide a larger support area, which helps the reinforcing plate 6 to better withstand loads and stresses, and also ensures the stability of the fin 8 itself.

[0027] Referring to Figs. 1-3The shaft hole 2 is used to ensure the installation precision between the pulley body 1 and the rotating shaft 4, reduce the vibration and eccentricity phenomenon during operation, and improve the stability and reliability of transmission.

[0028] With reference to Figs. 1-3 The plug block 5 is fixed on one side of the rotating shaft 4, and the key groove 3 is arranged on the pulley body 1 and matched with the plug block 5. The matching of the plug block 5 and the key groove 3 can prevent the relative rotation between the pulley body 1 and the rotating shaft 4, ensure the synchronous rotation of the pulley body 1 and the rotating shaft 4, and improve the stability and reliability of transmission.

[0029] With reference to Fig. 2 The plug hole 7 is arranged on the reinforcing plate 6 and used for the rotating shaft 4 to pass through the reinforcing plate 6, so that the rotating shaft 4 can smoothly pass through the reinforcing plate 6, the coordination and integrity of the whole structure of the pulley body 1 are ensured, and meanwhile, when the rotating shaft 4 passes through the reinforcing plate 6, the reinforcing plate 6 can support the rotating shaft 4 to a certain extent, reduce the deflection of the rotating shaft 4, and improve the rigidity and stability of the rotating shaft 4.
