Description

Technical Field

[0001] The utility model belongs to the technical field of synchronous belts, and in particular relates to an anti-slip transmission belt used for traction transmission. Background Art

[0002] The synchronous belt is a traction transmission part that combines the advantages of chains, gears and V-belts, and is widely used in fields involving mechanical transmission.

[0003] Most of the existing synchronous belts use glass fiber as a reinforcement layer, but the bending fatigue of glass fiber is large, and the fiber is prone to breakage after continuous use, and the service life is short. The existing patent document (Announcement No.: CN213360953U) discloses a "special synchronous belt resistant to acid and benzene", in which an anti-stretching strip is provided inside the synchronous belt. The anti-stretching strip is made of glass fiber cord as raw material and treated with chloroprene rubber, which also has the above technical problems. Summary of the invention

[0004] The utility model aims to solve the above technical problems existing in the prior art and provide an anti-skid transmission belt for traction transmission, which has novel design, high structural strength, strong tensile strength and long service life.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A non-slip transmission belt for traction transmission, comprising: a belt body, the inner surface of which is evenly distributed with transmission teeth, and a tooth groove is formed between two adjacent transmission teeth; the belt body is characterized in that: a tensile body is arranged in the belt body, the tensile body comprises a first steel wire core, a second steel wire core and a third steel wire core, and the third steel wire core is wound between the first steel wire core and the second steel wire core. The transmission belt has a novel design, high structural strength, strong tensile resistance and long service life.

[0007] Furthermore, a fourth steel wire core is connected between two adjacent tensile bodies to connect the tensile bodies into one, restrain each other, and form a structurally stable tensile layer with a large coverage area and strong tensile resistance. It can effectively resist the tension in the length and width directions of the belt and is not easy to break, thereby extending the service life of the belt.

[0008] Furthermore, the fourth steel wire core is wound between two adjacent third steel wire cores, with a large contact area and high connection strength.

[0009] Furthermore, the transmission teeth are provided with heat dissipation holes, and air flows through the heat dissipation holes to take away the heat from the surface of the transmission teeth, thereby achieving a good heat dissipation effect and preventing the transmission teeth from being deformed due to heat accumulation.

[0010] Furthermore, the outer surface of the belt body is evenly provided with anti-skid grooves, which increases the roughness of the outer surface of the belt body, thereby increasing the anti-skid performance of the belt body, and reducing the manufacturing materials of the belt body, saving material costs.

[0011] Furthermore, the surface of the transmission tooth is wrapped with elastic nylon cloth, which improves the wear resistance and shear strength of the transmission tooth and prolongs the service life.

[0012] Furthermore, the tooth groove is a trapezoidal tooth groove or a concave-top parabolic tooth groove, which has a good meshing effect with the matching gear teeth, can reduce impact, and has low transmission noise.

[0013] The utility model has the following beneficial effects due to the adoption of the above technical solution:

[0014] 1. The third steel wire core connects the first steel wire core and the second steel wire core into one, which effectively improves the tensile strength of the tensile body, thereby improving the structural strength and tensile strength of the belt body, avoiding elastic fatigue caused by frequent bending of the belt body, and preventing cracks on the surface of the belt body from affecting its use.

[0015] 2. A fourth steel wire core is connected between two adjacent tensile bodies to connect the tensile bodies into one, restrain each other, and form a tensile layer with a stable structure. It has a large coverage area and strong tensile resistance. It can effectively resist the tension in the length and width directions of the belt body and is not easy to break, thereby extending the service life of the belt body.
