AI Technical Summary
[0002]农机包布V带是专为农业机械设计的传动部件,具有耐磨、耐油、抗疲劳等特性,适用于收割机、脱粒机等设备,在实际的农机使用中不可避免的出现大负荷运行的情况发生,这种情况下长期使用会加速包布层疲劳,出现裂纹、分层,最终导致断裂,为解决这个问题,改进型的V带采用抗拉强度更高的受力筋来承受更大的拉力,但V带安装在V形轮内,强大拉力同时给V带施加了与V形轮之间的挤压力,这种挤压力过大会使V带横向的橡胶碎裂,因此需要设计一种能承受较大压力保持结构完整的农机包布V带
本实用新型通过纵向受力筋承受拉力,横向受力网来承托V带压在V形轮上而形成的横向分散力,使V带在承受较大拉力导致横向分散力较大时,横向受力网对V带横向进行加固,使V带能够承受较大压力仍保持结构完整。

Abstract
Description
Technical Field
[0001] This utility model relates to the field of V-belt production equipment, specifically to a V-belt for agricultural machinery covering. Background Technology
[0002] Agricultural machinery-covered V-belts are transmission components specifically designed for agricultural machinery. They possess characteristics such as wear resistance, oil resistance, and fatigue resistance, and are suitable for equipment such as harvesters and threshers. In actual agricultural machinery use, high-load operation is inevitable. Under such conditions, long-term use will accelerate the fatigue of the covering layer, leading to cracks, delamination, and ultimately breakage. To solve this problem, improved V-belts use reinforcing ribs with higher tensile strength to withstand greater tension. However, since the V-belt is installed inside the V-shaped pulley, the strong tension also applies a compressive force between the V-belt and the V-shaped pulley. Excessive compressive force can cause the rubber of the V-belt to break laterally. Therefore, it is necessary to design an agricultural machinery-covered V-belt that can withstand greater pressure while maintaining structural integrity. Utility Model Content
[0003] The purpose of this invention is to provide a V-belt for agricultural machinery that has the advantage of maintaining structural integrity while withstanding greater pressure.
[0004] The technical solution adopted is as follows: A V-belt for agricultural machinery includes a covering layer, a rubber layer, and a skeleton layer. The skeleton layer includes a transverse stress net and several longitudinal stress ribs. Both the transverse stress net and the longitudinal stress ribs are embedded in the rubber layer. The rubber layer is disposed within the covering layer. The covering layer includes an outer covering layer and an inner covering layer.
[0005] Preferably, both the transverse stress net and the longitudinal stress rib are provided with burrs on their exterior.
[0006] Preferably, the inner side of the outer covering fabric and the outer side of the inner covering fabric are provided with several toothed grooves, and the toothed grooves of the outer covering fabric correspond to the toothed grooves of the inner covering fabric.
[0007] Preferably, the transverse stress net and the longitudinal stress rib are respectively located at the inner and outer ends of the V-belt.
[0008] Preferably, the mesh of the transverse stress-bearing mesh is rectangular.
[0009] Compared to existing technologies, the advantages are: This invention uses longitudinal reinforcing ribs to bear tensile force and transverse reinforcing mesh to support the transverse dispersion force formed when the V-belt presses on the V-shaped wheel. When the V-belt is subjected to large tensile force, resulting in a large transverse dispersion force, the transverse reinforcing mesh strengthens the V-belt laterally, enabling the V-belt to withstand greater pressure while maintaining structural integrity. Attached Figure Description
[0010] Figure 1This is a cross-sectional structural diagram of a V-belt for agricultural machinery covering according to this utility model; Figure 2 This is a schematic diagram of the transverse force-bearing net structure of a V-belt wrapped with agricultural machinery according to this utility model.
[0011] In the diagram: 1. Rubber layer; 2. Transverse stress net; 3. Longitudinal stress reinforcement; 4. Outer fabric; 5. Inner fabric. Detailed Implementation
[0012] The present invention will be further described below with reference to specific embodiments, such as... Figures 1 to 2 As shown: Example 1: A V-belt for agricultural machinery, comprising a fabric layer, a rubber layer 1, and a skeleton layer. The skeleton layer includes a transverse force-bearing mesh 2 and several longitudinal force-bearing ribs 3. Both the transverse force-bearing mesh 2 and the longitudinal force-bearing ribs 3 are embedded within the rubber layer 1. The rubber layer 1 is in the shape of an inverted trapezoid. The transverse force-bearing mesh 2 is used to bear the transverse dispersion force of the V-belt, and the longitudinal force-bearing ribs 3 are used to bear the longitudinal tension of the V-belt.
[0013] The rubber layer 1 is placed inside the fabric layer, which includes an outer fabric 4 and an inner fabric 5. The double-layer fabric layer improves the wear resistance of the V-belt. When the V-belt is subjected to a large tensile force, resulting in a large lateral dispersion force, the lateral force-bearing net 2 reinforces the V-belt laterally, so that the V-belt can withstand a large pressure and still maintain structural integrity.
[0014] Example 2: A V-belt for agricultural machinery, comprising a fabric layer, a rubber layer 1, and a skeleton layer. The skeleton layer includes a transverse force-bearing mesh 2 and several longitudinal force-bearing ribs 3. Both the transverse force-bearing mesh 2 and the longitudinal force-bearing ribs 3 are embedded within the rubber layer 1. The rubber layer 1 is in the shape of an inverted trapezoid. The mesh of the transverse force-bearing mesh 2 is rectangular. The transverse force-bearing mesh 2 is used to bear the transverse dispersion force of the V-belt, and the longitudinal force-bearing ribs 3 are used to bear the longitudinal tension of the V-belt. The transverse force-bearing mesh 2 and the longitudinal force-bearing ribs 3 are respectively located at the inner and outer ends of the V-belt.
[0015] Both the transverse stress net 2 and the longitudinal stress rib 3 are provided with burrs on their exterior. The burrs improve the adhesion between the transverse stress net 2 and the longitudinal stress rib 3 and the rubber layer 1, making the connection between the transverse stress net 2 and the longitudinal stress rib 3 and the rubber layer 1 tighter.
[0016] The rubber layer 1 is set inside the covering layer, which includes an outer covering 4 and an inner covering 5. The double-layer covering layer improves the wear resistance of the V-belt. Several toothed grooves are provided on the inner side of the outer covering 4 and the outer side of the inner covering 5. The toothed grooves of the outer covering 4 correspond to the toothed grooves of the inner covering 5. The corresponding toothed grooves strengthen the integrity of the outer covering 4 and the inner covering 5.
[0017] The working principle is as follows: When the V-belt is under tension, the longitudinal reinforcing rib 3 bears the tension. When the V-belt presses on the V-shaped pulley, the transverse reinforcing net 2 supports the transverse dispersion force formed by the V-belt pressing on the V-shaped pulley. When the V-belt is under a large tension and the transverse dispersion force is large, the transverse reinforcing net 2 reinforces the V-belt laterally, so that the V-belt can withstand a large pressure and still maintain its structural integrity.
[0018] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
