Description

Technical Field

[0001] The utility model relates to the field of synchronous belts, in particular to a wear-resistant synchronous belt. Background Art

[0002] A synchronous belt is a transmission device widely used in mechanical transmission systems. Its primary function is to transmit power from one shaft to another through pulleys, achieving precise synchronous transmission. A synchronous belt consists of a belt body, typically made of materials such as rubber and polyurethane, and a toothed section. The toothed section is reinforced with steel wire, fiberglass, or Kevlar to increase its strength and tensile strength.

[0003] After searching, the patent number is CN216951480U, which discloses a wear-resistant synchronous belt. The wear-resistant ridges replace the wear on the belt surface, thereby achieving a wear-resistant effect, preventing surface cracking and breakage caused by belt wear, and increasing the service life of the belt. The reinforcement strips increase the connection strength between two adjacent wear-resistant ridges, connecting each wear-resistant ridge into one body, restraining each other, and the wear-resistant ridges are not easy to separate from the belt body, which is reliable to use. The reinforcement strips can also replace the wear on the belt surface and achieve a wear-resistant effect. However, when the wear-resistant synchronous belt is in use, the toothed belt on it is fixedly connected to the synchronous belt. When the belt teeth on it are damaged, the synchronous belt is generally replaced as a whole, which is a waste of resource costs. Utility Model Content

When the existing wear-resistant synchronous belt is in use, the toothed belt thereon is fixedly connected to the synchronous belt. When the belt teeth thereon are damaged, the synchronous belt is generally replaced as a whole, which is a waste of resource costs.

[0005] In order to solve the above technical problems, the technical solution of the utility model is a wear-resistant synchronous belt, including a main belt and several groups of connecting belt teeth, the lower surfaces of several groups of the connecting belt teeth are fixedly connected with connecting strips, the upper surface of the main belt is provided with several groups of connecting grooves, and several groups of the connecting belt teeth are penetrated by movable rotating rods, both ends of the movable rotating rods are fixedly connected with movable baffles, and both side edges of the main belt are fixedly connected with anti-drawing strips.

[0009] As a further solution of the present invention: several groups of embedding grooves are provided on the upper surface of the main belt, the inner sides of several groups of the embedding grooves are fixedly connected with the second wear-resistant belt, several groups of first heat dissipation holes are penetrated on the second wear-resistant belt, several groups of second heat dissipation holes are penetrated on the inner bottom surface of the embedding groove, and the outer sides of several groups of the connecting belt teeth are fixedly connected with the first wear-resistant belt.

[0010] As a further solution of the present invention: a plurality of groups of the embedded grooves are distributed on the main belt at equal intervals, and a plurality of groups of the second wear-resistant belts and a plurality of groups of connecting belt teeth are arranged alternately.

[0013] Compared with the prior art, the beneficial effect of the present invention is that the meshing process of the synchronous belt and the gear is protected from wear by the cooperation of several groups of first wear-resistant belts and several groups of second wear-resistant belts. During the meshing process, a large amount of heat is easily generated due to friction, and then the heat is dissipated to the outside of the synchronous belt through the cooperation of several groups of first heat dissipation holes and several groups of second heat dissipation holes. While ensuring that the synchronous belt has wear resistance, the heat on the inside of the synchronous belt can be dissipated to prevent the first wear-resistant belt and the second wear-resistant belt from aging, thereby significantly improving the service life of the synchronous belt.

The lower surfaces of the several groups of connecting belt teeth 2 are fixedly connected with connecting strips 3. The upper surface of the main belt 1 is provided with several groups of connecting grooves 4. The several groups of connecting belt teeth 2 are penetrated by movable rotating rods 6. Both ends of the movable rotating rods 6 are fixedly connected with movable baffles 7. Both sides of the main belt 1 are fixedly connected with anti-tensile strips 14.

[0021] Several groups of connecting belt teeth 2 are evenly spaced on the inner surface of the main belt 1, and the cross-sectional shapes of several groups of connecting belt teeth 2 are all trapezoidal. Several groups of connecting strips 3 are slidingly connected to the main belt 1 through connecting grooves 4, and the cross-sectional shapes of several groups of connecting strips 3 are all T-shaped.

[0022] In this embodiment, the connection strip 3 and the connection groove 4 are matched to facilitate the installation and use of the connection belt teeth 2 .

[0023] Both ends of several groups of connecting belt teeth 2 are provided with cylindrical grooves 5, and two groups of reset springs 8 are sleeved on the outer side of the movable rotating rod 6, and the two ends of the reset spring 8 are fixedly connected to the movable baffle 7 and the inner end of the cylindrical groove 5 respectively, and the movable rotating rod 6 is rotatably connected to the connecting belt teeth 2.

[0024] In this embodiment, the two sets of movable baffles 7 are rotated and used by rotating the movable rotating rod 6 and the connecting belt teeth 2.

[0025] Specifically, through the cooperation of the T-shaped connecting strip 3 and the connecting groove 4, several groups of connecting belt teeth 2 are respectively connected to the main belt 1, and then the movable rotating rod 6 is connected to the rotation of the connecting belt teeth 2 and the reset spring 8 in the two groups of cylindrical grooves 5, so that the two groups of movable baffles 7 are respectively rotated to the two ends of the connecting belt teeth 2, realizing the convenient assembly function of the belt teeth and the synchronous belt, and also facilitating the partial replacement of the faulty synchronous belt teeth, which is relatively cost-effective.

[0026] Example 2, please refer to Figures 1-4 A wear-resistant synchronous belt, the upper surface of the main belt 1 is provided with several groups of embedding grooves 10, the inner sides of several groups of embedding grooves 10 are fixedly connected with second wear-resistant belts 11, several groups of first heat dissipation holes 12 are penetrated on the second wear-resistant belt 11, and several groups of second heat dissipation holes 13 are penetrated on the inner bottom surface of the embedding grooves 10, and the outer sides of several groups of connecting belt teeth 2 are fixedly connected with first wear-resistant belts 9.

[0027] Several groups of embedded grooves 10 are distributed on the main belt 1 at equal intervals, and several groups of second wear-resistant belts 11 and several groups of connecting belt teeth 2 are arranged alternately.
