Description

Technical Field

[0001] The utility model relates to a multi-wedge transmission belt, in particular to a transmission gear belt for a high-speed motor. Background Art

[0002] In automotive accessory systems, endless drive belts, particularly poly-V belts, are often used to transmit power. A drive belt structure consists of a backing layer primarily composed of rubber, a profile layer, such as a poly-V belt, and a cord layer located between the backing and profile layers. Drive belts are used in conjunction with accessory systems, such as pulleys, to transmit power. Geared drive belts are also used in technical fields requiring high-precision transmission, such as step-by-step transmissions.

[0003] At present, a Chinese patent with authorization announcement number CN220118572U discloses a transmission belt, which includes a rubber layer, a cord layer, a buffer layer, a cord layer and a profile layer from the outer circumference to the inner circumference, wherein the cord layer is interwoven with warp and weft, wherein the warp density is 150 to 210 threads / 10 cm, the warp twist is 150 to 700 twists / m, and the thickness of the cord layer is 0.20 mm to 0.40 mm. The technical problem to be solved is to improve the tear resistance of the belt back and reduce the cost at the same time.

[0004] The above-mentioned existing technical solutions have the following defects: the different materials of each layer lead to reduced fit between the materials of each layer, and the collision coefficient, tensile coefficient and yield strength are inconsistent, resulting in the innermost rubber layer experiencing degradation after a period of use, causing wrinkles in the inner rubber layer, thereby causing some risks during high-speed operation. Utility Model Content

[0005] The purpose of the utility model is to provide a transmission gear belt for a high-speed motor to solve the problems existing in the above-mentioned prior art.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A transmission gear belt for a high-speed motor includes a rubber ring, the inner wall of the rubber ring being a gear surface, a metal skeleton mesh embedded in the interior of the rubber ring, and a braided steel belt bonded and fixed to the outside of the rubber ring. The braided steel belt is composed of multiple groups of braided and pressed steel ropes. Both ends of the steel ropes are welded and fixed to joints. The surface of the joints is provided with serrated grooves. The steel ropes are twisted and formed by 6-8 strands of steel wire, and the twist of the steel ropes is 600 twists / m-800 twists / m.

[0008] By adopting the above technical solution, the twisted steel rope will have the problem of decreased twist and overall elongation when subjected to stress for a long time, but the strength will be reduced. Because the braided steel belt is composed of multiple groups of steel ropes, the overall strength of the braided steel belt is reduced to a limited extent, but the elongation of the braided steel belt is greatly increased, which is convenient for the rubber ring to extend synchronously with the extension, thereby protecting the rubber ring and strengthening the stress.

[0009] In a further embodiment, a plurality of metal sheets are bonded and provided at equal intervals on the periphery of the outer wall of the rubber ring.

[0010] By adopting the above technical solution, since the outer wall of the rubber ring needs to contact and apply force to the braided steel belt, the metal sheet is used for buffering, which can evenly distribute the force between the outer wall of the rubber ring and the braided steel belt, thereby avoiding local rupture of the rubber ring due to uneven force.

[0011] In a further embodiment, the metal skeleton mesh is formed by weaving steel wires with a diameter of 0.08 mm to 0.12 mm.

[0012] In a further embodiment, the steel wires form a grid structure, and the mesh aperture of the steel wires is 1 mm-1.5 mm.

[0013] In a further embodiment, the rubber ring is sequentially arranged as a central layer, a middle layer and an outer layer from the inside to the outside, and the metal skeleton mesh is embedded in the central layer.

[0014] In a further embodiment, the surface of the rubber ring is sprayed with an anti-oxidation layer.

[0015] In summary, the present invention has the following beneficial effects:

[0016] 1. When the twisted steel rope is under stress for a long time, the twist will decrease and the overall elongation will be increased, but the strength will be reduced. Because it is a braided steel belt composed of multiple groups of steel ropes, the overall strength of the braided steel belt is reduced to a limited extent, but the elongation of the braided steel belt is greatly increased, which is convenient for the rubber ring to extend synchronously with the extension, thereby protecting the rubber ring and strengthening the stress.

[0021] Example 1:

[0022] like Figure 1 As shown, a transmission gear belt for a high-speed motor includes a rubber ring 1, the inner wall of the rubber ring 1 is a gear surface, a metal skeleton net 2 is embedded in the interior of the rubber ring 1, a braided steel belt 3 is bonded and fixed to the outside of the rubber ring 1, the braided steel belt 3 is composed of multiple groups of steel ropes woven and pressed, both ends of the steel ropes are welded and fixed to the joint, the surface of the joint is provided with a serrated groove, the steel rope is twisted into shape by 6-8 strands of steel wire, the twist of the steel rope is 600 twists / m-800 twists / m, a plurality of metal sheets are bonded at equal intervals on the periphery of the outer wall of the rubber ring 1, the metal skeleton net 2 is braided and formed by steel wires with a diameter of 0.08mm-0.12mm, the steel wires form a grid structure, and the grid aperture of the steel wires is 1mm-1.5mm, the rubber ring 1 is arranged from the inside to the outside as a center layer, a middle layer and an outer layer, the metal skeleton net 2 is embedded in the center layer, and the surface of the rubber ring 1 is sprayed with an anti-oxidation layer.

[0023] Specific implementation process: When the twisted steel rope is in use and subjected to stress for a long time, the twist will decrease and the overall elongation will occur, but the strength will be reduced. Because it is a braided steel belt composed of multiple groups of steel ropes, the overall strength of the braided steel belt is reduced to a limited extent, but the elongation of the braided steel belt is greatly increased, which is convenient for the rubber ring to extend synchronously when it is extended, thereby protecting the rubber ring and strengthening the stress.
