High-precision tensile conical tooth synchronous belt and enhanced framework thereof

Abstract

The invention discloses a high-precision tensile conical tooth synchronous belt and a reinforcing framework thereof, and belongs to the technical field of synchronous belts. The framework is composed of conical teeth, a reinforcing net, force holding ribs and a bottom plate, and the transmission performance of the synchronous belt is remarkably improved by optimizing the internal structure. The bevel teeth are arranged in a longitudinal and transverse dense mode and are composed of teeth, tooth rods and tooth holders, and the tooth holders are fixed to the flexible bottom plate and combined with the pressing pad on the upper portion, so that positioning is guaranteed, and the elasticity ratio is given. The bearing ribs longitudinally penetrate through the conical teeth to enhance the tensile strength; the reinforcing net limits displacement of the conical teeth and improves transverse stability. The teeth are made of solid metal materials, the conical barrel-shaped structures of the teeth are matched with the concave conical barrel-shaped gears, and multi-point meshing and automatic correction are achieved. Through a unique bevel gear meshing structure and an internal reinforcing system, the problems that stress of a tooth root of a traditional synchronous belt is concentrated, and stress is uneven are solved, so that the synchronous belt has remarkable advantages in the special transmission fields of high precision, strong force, uniform load distribution, long service life and the like.

Description

Technical Field

[0001] The present invention belongs to the technical field of synchronous belts, and particularly relates to a high-precision tensile conical-tooth synchronous belt and its reinforcement structure. Background Art

[0002] In traditional synchronous belt drive systems, although conventional trapezoidal-tooth or circular-arc-tooth synchronous belts can meet general drive requirements, they still have obvious limitations under special working conditions such as high precision, heavy load, and long life. Synchronous belts in the prior art generally adopt a composite structure of a rubber matrix and a fiber reinforcement layer, and their tooth parts are mostly integrally formed with a single material, resulting in problems such as stress concentration at the tooth root, uneven tooth surface wear, and insufficient tensile strength. Especially in drive applications that require multi-point meshing and high synchronous accuracy, traditional synchronous belts often suffer from a decrease in drive accuracy and a shortened service life due to tooth profile deformation and belt body stretching.

[0003] In addition, the existing synchronous belt structure lacks effective longitudinal tensile and lateral positioning mechanisms, and is prone to tooth pitch cumulative error under long-term alternating loads, affecting drive stability. Although some improved synchronous belts attempt to improve performance by increasing reinforcing fibers or changing the tooth profile, they have not fundamentally solved the core problems such as uneven stress distribution inside the belt body and insufficient tooth positioning accuracy.

[0004] Therefore, there is an urgent need to develop a new synchronous belt structure with an optimized internal structure and enhanced mechanical properties to meet the requirements of modern industry for high-precision, high-strength, and long-life drive belts. Summary of the Invention

[0005] To solve the above technical problems, the present invention provides a high-precision tensile conical-tooth synchronous belt and its reinforcement structure.

[0006] To achieve the above invention object, the present invention adopts the following technical solutions: A high-precision tensile conical-tooth synchronous belt and its reinforcement structure, comprising: Conical teeth, which are composed of tooth tips, tooth rods, and tooth seats. The tooth seats are regular conical solid cones, and their bottoms are fixedly connected to the bottom plate; Reinforcing mesh, horizontally arranged above the conical teeth, is a rectangular grid structure, and its intersection points are provided with hole rings, and the hole rings are sleeved on the tooth rods; Supporting ribs, longitudinally arranged along the middle part of the conical teeth, are hoop-connected or inserted and connected with the tooth rods; Bottom plate, which is a flexible metal plate, and its upper surface is provided with multiple line-position display marking points, and the tooth seats are fixedly arranged according to the marking points.

[0007] Preferably, the tooth tips are regular conical solid cylinder structures made of metal, without a tip at the top, the middle and lower parts of the cylinder are enlarged, and a flange seat is provided at the bottom, and they are exposed outside the traditional belt body.

[0008] Preferably, a pressure pad is provided on the upper conical part of the tooth seat. The pressure pad is a horizontally sleeved pad, which is used to limit the parallel displacement and elastic floating ratio of the tooth bar.

[0009] Preferably, the force-bearing ribs are fiber clusters or wire compilation materials, and their diameter is 1 / 3 of that of the tooth bar.

[0010] Preferably, the bottom plate and the tooth seat are fixedly connected by welding.

[0011] Preferably, the conical teeth are densely arranged vertically and horizontally, and the arrangement distance is such that the longitudinal spacing is greater than the transverse spacing.

[0012] Preferably, the reinforcing mesh, the force-bearing ribs, the bottom plate, the tooth bar, the tooth seat and the pressure pad are all hidden components, and are wrapped and covered by the rubber or colloid structure of the traditional belt body.

[0013] Preferably, the tooth is adapted to and meshes with an inner concave conical cylinder type or a porous hollowed-out type gear.

[0014] Preferably, the dense arrangement of the conical teeth and the limiting effect of the reinforcing mesh enable the synchronous belt to have the capabilities of multi-point meshing, automatic correction and uniform transmission.

[0015] Preferably, a synchronous belt includes the above-mentioned conical tooth synchronous belt structure.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The high-precision tensile conical tooth synchronous belt and its enhanced structure of the present invention, by adopting a conical tooth structure arranged densely vertically and horizontally, combined with the synergistic effect of the reinforcing mesh, the force-bearing ribs and the flexible bottom plate, significantly improve the transmission precision and load-bearing capacity of the synchronous belt. The conical meshing design of the conical teeth can automatically correct the position deviation, ensure the synchronism of multi-point meshing, and at the same time enhance the wear resistance of the tooth surface and extend the service life. The longitudinal arrangement of the force-bearing ribs greatly improves the tensile strength of the belt body, while the reinforcing mesh effectively limits the horizontal displacement of the conical teeth and enhances the lateral stability. The cooperation of the flexible bottom plate and the pressure pad structure gives the belt body a reasonable elastic ratio, making it have a certain bending adaptability. In addition, the solid metal material and the optimized structure design of the conical teeth effectively disperse the tooth root stress, avoiding the stress concentration problem of the traditional synchronous belt, and further improving the transmission reliability and durability. The innovation of the overall structure makes the present invention have significant advantages in special transmission fields such as high precision, strong force, uniform load and long life.

The pressure pad 131 is a horizontally placed pad, and the purpose is to limit the parallel displacement of the tooth rod 12 and the upward elastic floating ratio. The number of the pressure pads 131 is the same as the number of the bevel gears 1; at the bottom of the tooth seat 13 is the bottom plate 4. The bottom plate 4 is a flexible metal plate, and multiple line-position display marking points are arranged on the upper surface of the bottom plate 4. The tooth seats 13 are arranged according to the line-position display marking points, and the bottom plate 4 is fixedly connected to the tooth seat 13, and the connection method is preferably welding.

[0026] Furthermore, the bearing bars 3 are longitudinal tension bars, aiming to enhance the longitudinal tensile strength of the belt body; there are multiple bearing bars 3, and each is arranged longitudinally along the conical teeth 1.
