Problems solved by technology

Then the belt is constantly bent and squeezed during high-speed operation and under the action of friction, the V-belt is prone to heat. The higher the speed, the greater the load, the higher the temperature rise, and the belt will become softer and stiffer in the lateral direction as the temperature rises. also drops significantly, the belt will roll over and fail

Embodiment 1

[0031] see figure 1 , the present embodiment provides an ATV belt, which is sequentially provided with a bottom cloth layer 1, a bottom rubber 2, a skeleton layer 3, a top rubber 4 and a top cloth layer 5 from the inside to the outside (from bottom to top in the figure). In the example, the bottom rubber 2 and the top rubber 4 are EPDM rubber, which can be used for a long time at 120-150 °C, which solves the problem of belt aging. The bottom rubber 2 is provided with bottom teeth 21, and the top rubber 4 is provided with top teeth 41. The belt drive has low bending stress, good dynamic bending performance, good heat dissipation performance, and has the advantage of reducing the temperature of the belt itself. . The skeleton layer 3 is provided with an aramid cord 31 along the belt direction, so that no heat shrinkage occurs during transmission and the service life is increased. The bottom rubber 2 is provided with aramid short fibers with a length of 1mm along the direction ...

Embodiment 2

[0033] The present embodiment provides a formula for the above-mentioned ATV belt, characterized in that:

[0034] The primer includes the following components by weight:

[0035] 100 parts of EPDM; 18-23 parts of aramid fiber; 1.5-2.0 parts of zinc stearate; 3-6 parts of zinc oxide; 5-6.5 parts of accelerator ZDMA; 2.0-3 parts of accelerator TAIC; anti-aging agent 4010NA 1-1.5 parts; anti-aging agent RD 1-1.5 parts; white carbon black 8-15 parts; N550 carbon black 35-40 parts; paraffin oil 5-8 parts; anti-scorch agent 0.4-0.6 parts; peroxide curing agent 5- 7 servings;

[0036] Please refer to Table 1 and Table 2 below, the primer adopts the following two groups of formulas in different parts by weight:

Embodiment 3

[0058] The present embodiment provides a method for processing an ATV belt, including rubber mixing, sheeting and splicing, wherein the rubber mixing includes one-stage mixing and two-stage mixing;

[0059] A blend:

[0060] The temperature of the internal mixer is less than 90 °C, and the ethylene-propylene diene rubber is added for 30 seconds; then anti-aging agent, accelerator, zinc oxide, zinc stearate and aramid fiber are added (during the top rubber mixing, basket cotton is also added. powder) for 90 seconds; add 2 / 3 carbon black for refining (add calcium carbonate when the top rubber is mixed) for 60 seconds; add 1 / 3 carbon black and paraffin oil for 60 seconds; lift the top bolt for cleaning; continue mixing 90 seconds, the temperature is below 160 ℃, and the material is discharged; then the sheet is cooled on the open mill, and the temperature of the unloading sheet is controlled at 110-120 ℃;

[0061] Two-stage mixing:

[0062] When the temperature of the internal ...

Abstract

The invention discloses a beach buggy belt, and relates to the technical field of transmission belts. A bottom cloth layer, bottom rubber, a framework layer, top rubber and a top cloth layer are sequentially arranged from inside to outside; bottom teeth are arranged on the bottom rubber; top teeth are arranged on the top rubber; aramid fiber ropes are arranged on the framework layer in the direction of the belt; and aramid fibers are arranged in the bottom rubber in the direction perpendicular to the belt. The invention further discloses a formula and a processing method of the beach buggy belt. The temperature resistance, the transverse rigidity and the low-compression heat generation performance of the belt are well considered.

Description

technical field [0001] The invention relates to the technical field of transmission belts, in particular to an ATV belt and its formula and processing method. Background technique [0002] The ATV belt is an important part in ATV. The belt belongs to friction transmission, which relies on the friction between the belt and the pulley to transmit power. In addition, the ATV belt is also a variable speed belt. The acceleration and deceleration of the ATV are realized by changing the diameter of the driving wheel and the driven wheel, that is, the transmission ratio is infinitely adjusted. The operation of the entire ATV relies on this belt to transmit power, and the conditions are very harsh, and it is difficult for ordinary belts to meet the requirements. [0003] In order to prevent the belt from slipping during transmission, that is, a certain tension must be applied to the belt during transmission to generate positive pressure friction for transmission. Then in the high-s...
