Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery transmission, in particular to a trimmed double-sided toothed V-belt structure for high-horsepower agricultural machinery. Background Art

[0002] Double-sided gear speed V-belt is a high-power toothed V-belt, generally used in beach cars or high-power motorcycles. It has a large transmission power and a thick belt body. Currently, most high-power V-belts have no teeth on the upper and lower parts or a small tooth structure on the bottom.

[0003] The existing referenceable Chinese utility model patent has a publication number of CN205479128U, which discloses a tooth structure of a double-sided gear variable speed V-belt, including a double-sided gear top cloth and a top rubber, a buffer layer below the top rubber, a cord inside the buffer layer, a bottom rubber below the buffer layer, and a bottom cloth connected to the bottom rubber below the bottom rubber, forming a tooth structure of the double-sided gear variable speed V-belt as a whole; the tooth structure of the double-sided gear variable speed V-belt has a total height of 15 mm, a low tooth pitch of 12.3 mm, a tooth depth of 6 mm, a top tooth pitch of 9.3 mm, a tooth depth of 3.8 mm, a low tooth tooth angle of 38°, a top tooth tooth angle of 46°, a tooth root radius R of 1.5 mm, and a tooth top of 4.2 mm. The advantages of the tooth structure of the double-sided tooth variable speed V-belt are: small tooth bending stress, high load, high tooth shear strength, good dynamic bending, and high transmission efficiency. It can meet the requirements of transmission power and adapt to occasions with small bending radius; this tooth structure is mainly suitable for the tooth structure of toothed belts with high power transmission and thick belt body.

[0004] When the V-belt is transmitting, a certain relative pressure needs to be maintained between the V-belt and the pulleys on both sides to achieve the transmission effect, so that the V-belt is in a slightly stretched state. When cracks appear on the surface of the V-belt, the cracks will gradually increase due to the V-belt being in a stretched state, and eventually the V-belt will break. At the same time, the toothed structure between the inner and outer sides of the existing V-belt will wear during use, resulting in a decrease in the flexibility of the V-belt. Utility Model Content

[0015] Compared with the prior art, the utility model provides a double-sided toothed V-belt structure for high-horsepower agricultural machinery, which has the following beneficial effects:

[0016] 1. The utility model sets an outer fiber layer, which is a mixture of polyester fiber and fluororubber. The polyester fiber and fluororubber have good wear resistance. The fluororubber can facilitate the bonding between the outer fiber layer and the wear-resistant layer, thereby improving the wear resistance of the V-belt. When the outer fiber layer is worn too much, the inner wear-resistant layer is exposed. The wear-resistant layer is butyl rubber, and the fiberboard is symmetrically arranged at the ends of the toothed structure on the inner and outer sides of the wear-resistant layer with the center of the wear-resistant layer as the reference. The butyl rubber has good wear resistance, and after the butyl rubber on the surface of the wear-resistant layer is worn, the inner fiberboard will be exposed.

When a layer breaks, it cannot be transmitted to other layers, and the external fiber layer is made of a mixture of polyester fiber and fluororubber. The polyester fiber can reduce the probability of cracks in the external fiber layer under the action of external force. At the same time, the polyester fiber can pull the cracks when cracks appear in the external fiber layer to reduce the speed of crack diffusion. The anti-breaking rope is symmetrically arranged between the tooth-shaped structures on the upper and lower sides of the filling layer with the center of the belt body as the reference, and the anti-breaking rope can increase the strength of the filling layer. The metal wire is symmetrically arranged on the left and right sides of the wear-resistant layer with the center of the wear-resistant layer as the reference, and the metal wire can prevent the cracks in the wear-resistant layer from spreading. This method can prevent the cracks on the V-belt from spreading quickly and affecting the service life of the V-belt. BRIEF DESCRIPTION OF THE DRAWINGS
