Abstract
Description
Technical Field
[0001] This utility model relates to the field of V-belt production technology, specifically to a fabric-covered V-belt with anti-aging properties. Background Technology
[0002] The friction between the V-belt and the V-belt pulley during use causes the V-belt to operate in a high-temperature environment. Prolonged use can easily lead to aging of the V-belt, reducing its service life. In order to improve the anti-aging performance of the V-belt and increase its service life, this application proposes an anti-aging fabric-covered V-belt. Utility Model Content
[0003] In view of the shortcomings of the existing technology, this utility model provides a fabric-covered V-belt with anti-aging properties.
[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a fabric-covered V-belt with anti-aging properties, comprising three sets of inner cores, a first fabric layer wound between the three sets of inner cores, a first impregnated yarn layer spirally wound on the outside of the first fabric layer, a heat insulation layer wound on the outside of the first impregnated yarn layer, a second impregnated yarn layer wound on the outside of the heat insulation layer, and a second fabric layer provided on the outside of the second impregnated yarn layer.
[0005] Preferably, after the first inner core is wrapped around the first inner core, the second inner core is wrapped around it, and after the second inner core is wrapped around it, the third inner core is wrapped around it.
[0006] Preferably, the heat insulation layer is made of aramid fiber.
[0007] Preferably, the inner core is made of high-temperature resistant steel wire rope.
[0008] This utility model provides a fabric-covered V-belt with anti-aging properties, which has the following beneficial effects:
[0009] This anti-aging fabric-covered V-belt can prevent the heat generated by friction when driving the V-belt pulley from being transferred to the inside of the V-belt through the heat insulation layer, thus minimizing heat damage to the internal structure of the V-belt, thereby improving its anti-aging performance and increasing its service life.

[0013] The present invention will be further described below with reference to specific embodiments, such as... Figures 1 to 2 As shown:
[0014] Example 1: A fabric-covered V-belt with anti-aging properties includes three sets of inner cores, and a first fabric layer 2 is wound between the three sets of inner cores to ensure stability between the three sets of inner cores;
[0015] A first impregnated yarn layer 3 is spirally wound on the outside of the first fabric layer 2. The spiral winding can better secure the inner core. A heat insulation layer 4 is wound on the outside of the first impregnated yarn layer 3. With the setting of the heat insulation layer 4, the wear and tear of the V-belt inside the V-belt is reduced as much as possible by the external environment when the V-belt is working.
[0016] The outer side of the heat insulation layer 4 is wrapped with a second impregnated yarn layer 5, and a second cloth wrapping layer 6 is provided on the outer side of the second impregnated yarn layer 5. The second impregnated yarn layer 5 can reinforce the heat insulation layer 4, thereby reducing the wear on the inside of the V belt when the second cloth wrapping layer 6 contacts the V belt pulley.
[0017] Example 2: A fabric-covered V-belt with anti-aging properties includes three sets of inner cores, the inner cores being made of high-temperature resistant steel wire rope, and a first fabric layer 2 is wound between the three sets of inner cores to ensure stability between the three sets of inner cores;
[0018] After the first inner core 7 is wrapped with the first inner core 2, the second inner core 8 is wrapped with it. After the second inner core 8 is wrapped, the third inner core 9 is wrapped with it.
[0019] A first impregnated yarn layer 3 is spirally wound on the outside of the first fabric layer 2. The spiral winding can better secure the inner core. A heat insulation layer 4 is wound on the outside of the first impregnated yarn layer 3. The heat insulation layer 4 is made of aramid fiber. By setting the heat insulation layer 4, the wear and tear of the V-belt inside the V-belt is reduced as much as possible when the V-belt is working.
[0020] The outer side of the heat insulation layer 4 is wrapped with a second impregnated yarn layer 5, and a second cloth wrapping layer 6 is provided on the outer side of the second impregnated yarn layer 5. The second impregnated yarn layer 5 can reinforce the heat insulation layer 4, thereby reducing the wear on the inside of the V belt when the second cloth wrapping layer 6 contacts the V belt pulley.
[0021] Working principle:
[0022] When this V-belt drive is used on the V-belt pulley, the second cloth layer 6 comes into contact with the V-belt pulley. During the transmission process, the second cloth layer 6 will gradually generate heat through friction. The heat insulation layer 4 is set to isolate the heat generated by the transmission, so as to avoid the heat from damaging the inside of the V-belt pulley as much as possible, thereby improving its anti-aging performance and increasing its service life.
[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
