Embodiment 1，1

[0038] Embodiment 1, 1, composition structure of irregular helical V-ribbed belt

[0039] Such as Figure 1~2 As shown, an irregular helical V-ribbed belt includes a belt body 1, a belt back 2 on the outer surface of the belt body 1, and a plurality of wedge teeth 3 on the inner surface of the belt body 1, and the wedge teeth 3 are along the length direction of the belt body 1. Extending, on each wedge tooth 3 along the length direction of the belt body, there are slots 5 inclined in several directions, the spacing between the slots 5 is not equal, and the angle θ between the inclination direction of the slots 5 and the length direction of the belt is 45°. This included angle makes the irregular helical teeth on the V-ribbed belt more streamlined, and has a better effect on reducing the abnormal sound of cut-in and air-flow pinching when the belt is running. The groove depth of the tooth groove 5 is 1.5mm-2.0mm, and the groove width is 5mm-15mm.

Embodiment 2

[0072] Embodiment 2, 1, composition structure of irregular helical V-ribbed belt

[0073] Such as Figure 1~2 As shown, an irregular helical V-ribbed belt includes a belt body 1, a belt back 2 on the outer surface of the belt body 1, and a plurality of wedge teeth 3 on the inner surface of the belt body 1, and the wedge teeth 3 are along the length direction of the belt body 1. Extending, on each wedge tooth 3 along the length direction of the belt body, there are slots 5 inclined in several directions, the spacing between the slots 5 is not equal, and the angle θ between the inclination direction of the slots 5 and the length direction of the belt is 20°. This included angle makes the irregular helical teeth on the V-ribbed belt more streamlined, and has a better effect on reducing the abnormal sound of cut-in and air-flow pinching when the belt is running. The groove depth of the tooth groove 5 is 1.5mm-2.0mm, and the groove width is 5mm-15mm.

Embodiment 3～5

[0106] Except for the angle between the inclination direction of the tooth groove and the length direction of the belt body as shown in the table below, the rest of the operations are the same as in Example 1

[0107]

[0108] The irregular helical V-ribbed belt prepared in Examples 3-5 is tested for performance, and the test results are superior to those of no-toothed, straight-toothed and regular helical-toothed V-ribbed belts in terms of noise, fatigue life, and belt vibration , reached the performance requirements of the car V-belt.

Abstract

The invention relates to an irregular helical multi-wedge belt which comprises a belt body (1), a belt back (2) on the outer surface of the belt body (1), and multiple wedge teeth (3) on the inner surface of the a belt body (1), wherein the wedge teeth (3) extend along the length direction of the belt body (1); a plurality of inclined toothed grooves (5) are formed in each wedge tooth (3) along the length direction of the belt body; the distances among the toothed grooves (5) are unequal; and an included angle theta between the inclination direction of the toothed grooves (5) and the length direction of the belt body is more than 0 degree and less than 90 degrees. The invention further relates to a preparation method of the irregular helical multi-wedge belt. The multi-wedge belt disclosed by the invention is long in service life, a running shock problem of a multi-wedge belt of an automobile during operating is solved, the problems of cut-in abnormal sound and airflow trapping abnormal sound are solved, the preparation method disclosed by the invention is simple in process, and lots of material cost can be saved.

Description

technical field [0001] The invention relates to the field of optimal design of an engine gear train system, in particular to an irregular helical ribbed belt and a preparation method thereof. Background technique [0002] Automobile V-belt transmission is the most advanced transmission mode in the front-end wheel train of the engine. In particular, the serpentine transmission can be carried out in the transmission, which optimizes the layout of the engine wheel train and increases the feasibility of the complex design of the wheel train. It provides the best solution for the miniaturization and compact design of the engine. [0003] In the past, the V-ribbed belt for automobiles consisted of a belt back, a tensile body, adhesive glue, and wedge teeth. There was no helical tooth shape or a tooth shape in the wedge-tooth part of the automobile V-ribbed belt, but the tooth shape was a regular right-angle tooth. In general, the V-ribbed belt of the automobile with the above-men...
