Description

Technical Field

[0001] The utility model relates to the technical field of pulley protection, in particular to a pulley heat dissipation protection component. Background Art

[0002] Pulleys are disc-hub parts. They are generally relatively large in size. The manufacturing process is generally based on casting and forging. Generally, larger designs are cast, and the material is generally cast iron (better casting performance), and cast steel is rarely used (steel has poor casting performance); generally, smaller ones can be designed for forging, and the material is steel. Pulleys are mainly used in situations where power is transmitted over long distances, such as the output of small diesel engines, agricultural vehicles, tractors, automobiles, mining machinery, mechanical processing equipment, textile machinery, packaging machinery, lathes, forging machines, some small-horsepower motorcycle power transmission, agricultural machinery power transmission, air compressors, reducers, reducers, generators, cotton gins, etc.

[0003] In Chinese Patent 202322307017.9, the utility model discloses a pulley protective cover shell, including a fixed structure, a connecting structure, a drainage structure and a heat dissipation structure, wherein the connecting structure is mounted on the fixed structure, the fixed structure is connected to the operating equipment body, the drainage structure is mounted inside the connecting structure, and the heat dissipation structure is mounted on the connecting structure. The utility model is connected to the operating equipment body through the fixed structure, providing a stable installation support for the connecting structure; the connecting structure protects the pulley and the belt, and slows down the aging of the connecting parts; the water accumulated in the connecting structure is discharged through the drainage device; the heat dissipation structure dissipates the heat inside the connecting structure, and reduces the entry of external water into the connecting structure, thereby improving the practicality of the device.

[0004] The existing pulley protection assembly has a protective shell that cooperates with the heat dissipation holes and the anti-seepage holes to dissipate heat to the pulley inside the protective shell. Although it can reduce the damage to the pulley caused by residual moisture, it cannot be completely sealed. External moisture or dust will still enter the interior of the protective shell through the heat dissipation holes and adhere to the pulley, which can easily cause rust and aging of the pulley. In addition, the existing protective shell is fixed on the mounting seat by screwing screws and covers the outside of the pulley. When the pulley or belt is damaged and the protective shell needs to be removed for maintenance, it has to be removed with a screwdriver or other tools, which is a cumbersome operation.

[0005] Therefore, in order to solve the above problems, a pulley heat dissipation protection component is proposed. Utility Model Content

[0030] See also Figure 5As shown, a pulley heat dissipation protection component, the installation and fixing component 3 includes a protection component fixing seat 301, the interior of the protection component fixing seat 301 is fixedly connected with an annular ring 302, and the inner wall of the annular ring 302 is rollingly connected with a ball 303, the side of the ball 303 is provided with a pulley output shaft 304, and the end of the pulley output shaft 304 is installed with a pulley body 305, the side of the annular ring 302 is provided with a mounting bolt 306, the mounting bolt 306 runs through the interior of the protection component fixing seat 301, and the mounting bolt 306 is arranged at equal intervals about the outer wall of the annular ring 302, the side of the ball 303 is in contact with the pulley output shaft 304, and the ball 303 is arranged at equal angles with respect to the inner wall of the annular ring 302, and a rolling ball 303 is arranged at the position where the protection component fixing seat 301 contacts the pulley output shaft 304, so as to reduce the friction between the pulley output shaft 304 and the pulley output shaft 304.

[0031] Working principle: First, the protective component fixing seat 301 is installed and fixed on the machine using the mounting bolts 306. The pulley output shaft 304 is located inside the annular ring 302. The pulley protective housing 201 covers the outside of the pulley body 305 to protect the pulley body 305 and the belt. The heat generated by the pulley during operation will be transferred to the heat conduction panel 101. The heat conduction panel 101 transfers the heat to the heat dissipation fins 102 on its outer wall. The heat dissipation fins 102 dissipate the heat through heat exchange with the air. When the dissipated heat accumulates in the air, the heat generated by the pulley 304 is transferred to the heat conduction panel 101. When the fan mounting frame 103 is inside, the temperature relay 106 can detect the temperature inside the fan mounting frame 103 in real time. When the temperature reaches the set threshold of the temperature relay 106, the temperature relay 106 will control the start of the cooling fan 105. The rotating blades of the cooling fan 105 discharge the air carrying heat from the fan mounting frame 103. At the same time, new air from the outside enters the fan mounting frame 103 through the ventilation holes 104, forming a flowing airflow on the surface of the cooling fins 102, which helps to dissipate the heat on the cooling fins 102.

[0032] When the pulley body 305 is working, its pulley output shaft 304 rotates inside the annular ring 302, and at the same time rotates with the ball 303 in contact with it, thereby converting the sliding friction between the pulley output shaft 304 and the annular ring 302 into rolling friction. If the pulley is damaged and needs to be repaired, it is only necessary to pull the two lifting handles 204 outwards, moving the disassembly and assembly pins 205 until the end of the disassembly and assembly pins 205 are separated from the protective shell mounting ring 206. At this time, the pulley protective shell 201 can be removed. After the pulley protective shell 201 is removed, the pulley and the belt are exposed to the outside, and then they can be repaired.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model.
