Description

Technical Field

[0001] The utility model relates to the technical field of power transmission belts, in particular to a power transmission belt. Background Art

[0002] Power transmission belts are divided into poly-V belts, synchronous belts and V-belts, and various power transmission belts usually include an inner layer, a surface layer and a middle layer arranged between the inner layer and the surface layer. In the mold forming process of the power transmission belt, the inner layer and the surface layer are bonded to both sides of the middle layer by an adhesive, and then formed by a hot pressing process.

[0003] In the prior art, during the use of the power transmission belt, the edge of the power transmission belt often comes off due to deviation, wear or quality problems of the belt, which affects the service life of the power transmission belt and increases the cost of use. Utility Model Content

[0004] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0005] A power transmission belt comprises a surface layer, a middle layer and an inner layer;

[0006] The front and rear sides of the middle layer are provided with connecting blocks, and the surface layer and the inner layer are provided with card slots on the opposite sides of the middle layer;

[0007] When the middle layer is connected to the surface layer and the inner layer, the connecting block is arranged in the card slot.

[0008] Preferably, the surface layer is made of polyurethane material.

[0009] Preferably, the middle layer is made of fiber material.

[0010] Preferably, the inner layer is made of rubber material.

[0011] Preferably, a plurality of bosses are provided on the upper and lower sides of the middle layer, the bosses are integrally formed with the middle layer, and grooves are provided on the surface layer and the inner layer on opposite sides of the middle layer. When the middle layer is connected to the surface layer and the inner layer, the bosses are arranged in the grooves.

[0012] Preferably, the connection block is arranged between two bosses close to the side surface of the middle layer.

[0013] The utility model provides a power transmission belt, which has the following beneficial effects:

[0014] 1. In the utility model, the side edge of the power transmission belt is strengthened by arranging the connecting block in the card slot and connecting the middle layer with the side edges of the surface layer and the inner layer through a hot pressing process. During use, the edge detachment of the power transmission belt is reduced, thereby enhancing the service life of the power transmission belt.

[0015] 2. In the present invention, when the middle layer is connected to the surface layer and the inner layer, the boss is arranged in the groove, thereby increasing the contact area between the middle layer and the surface layer and the inner layer, thereby increasing the connection strength and further reducing the occurrence of edge detachment.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] See also Figure 1-3 The utility model provides a technical solution:

[0022] A power transmission belt, comprising:

[0023] The surface layer 10 is the outer covering layer of the power transmission belt, which is used to contact the external environment and the working material;

[0024] The middle layer 20 is the skeleton of the power transmission belt, providing strength and support;

[0025] An inner layer 30, which is located at the bottom of the power transmission belt and is used to contact the transmission wheel;

[0026] The middle layer 20 is provided with connecting blocks 22 on the front and rear sides, and the surface layer 10 and the inner layer 30 are provided with card slots 31 on the opposite sides of the middle layer 20 . When the middle layer 20 is connected with the surface layer 10 and the inner layer 30 , the connecting blocks 22 are arranged in the card slots 31 .

[0027] In the above, by setting the connecting block 22 in the slot 31 and forming the middle layer 20, the surface layer 10 and the inner layer 30 into one body through a hot pressing process, the side reinforcement of the power transmission belt is achieved. During use, the edge detachment of the power transmission belt is reduced, thereby enhancing the service life of the power transmission belt.

[0028] Specifically, the surface layer 10 is made of polyurethane material, the middle layer 20 is made of fiber material, and the inner layer 30 is made of rubber material.

[0029] See also Figure 2 In the present application, the second embodiment is also disclosed:

[0030] Different from the first embodiment: the middle layer 20 is further provided with a plurality of bosses 21 on the upper and lower sides, the bosses 21 are integrally formed with the middle layer 20, and the surface layer 10 and the inner layer 30 are provided with grooves 32 on opposite surfaces of the middle layer 20. When the middle layer 20 is connected with the surface layer 10 and the inner layer 30, the bosses 21 are arranged in the grooves 32, thereby increasing the contact area between the middle layer 20 and the surface layer 10 and the inner layer 30, thereby increasing the connection strength and further reducing the occurrence of edge detachment.

[0031] Specifically, Figure 2 It is described in: The connecting block 22 is arranged between two bosses 21 close to the side surface of the middle layer 20. After testing, it is found that compared with the outermost side of the connecting block 22, the connecting block 22 arranged between the first and second bosses 21 has better anti-edge separation effect and longer service life.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
