Problems solved by technology

However, none of the existing timing belts is in contact with the engine oil. In order to overcome the defects of large power consumption, high fuel consumption, high noise, and troublesome maintenance of the existing chain drive, it is necessary to use the timing belt in the engine oil. None of the belts can meet the requirements for use in automobile engine oil, and it needs to be improved

Embodiment 1

[0035] An automobile timing drive belt for immersion in oil, see figure 1 and figure 2 , including an annular belt body 5, a plurality of teeth 3 formed at intervals along the inner peripheral surface of the belt body and a core wire 2 embedded along the circumference of the belt body, the outer peripheral surface of the belt body is provided with a back fabric layer 1 The inner peripheral surface of the belt body is provided with a toothed fabric layer 4 covering the teeth, and the outer surface of the toothed fabric layer is coated with a fluorine-containing emulsion coating 6. The materials and preparation process of the above structures are as follows:

[0036] 1. Back fabric layer: use PA66 fiber twisted into yarn to weave the canvas, after the dipping treatment of dipping glue with the same main component as the main component of the belt body (hydrogenated nitrile rubber), coating method: dipping once , The front and back sides of the canvas are painted 3 times; then...

Embodiment 2

[0059] An automobile timing drive belt for immersion in oil, the specific structure and preparation method are the same as in Example 1, the difference is that:

[0060] Wherein, the preparation of the impregnating mortar: the mixing rubber and acetone are mixed to obtain the impregnating mortar, wherein the mass ratio of the mixing rubber and acetone is 1:6. The rubber compound is prepared by mixing the following components in parts by weight: hydrogenated nitrile rubber 2020L: 100; zinc oxide: 6; stearic acid: 2; phenolic adhesive resin: 6; carbon black N330: 55; Agent TP-95: 5; white carbon black: 12; crosslinking agent DCP: 5; co-crosslinking agent TAIC: 2.

Embodiment 3

[0062] An automobile timing drive belt for immersion in oil, the specific structure and preparation method are the same as in Example 1, the difference is that:

[0063] The main body of the belt is prepared by mixing the following components in parts by weight: hydrogenated nitrile rubber 2020L: 100; aramid staple fiber: 8; zinc oxide: 8; stearic acid: 2; carbon black N774: 65; Softener TP-95: 6; white carbon black: 12; crosslinking agent DCP: 4; sulfur: 0.8.

[0064] The production process of the oil-immersed automobile timing drive belt of the present invention is the same as that of the existing product except for the above-mentioned steps. No tensioning device is required during use, and the transmission belt can be completely submerged in engine oil to achieve the same service life as the engine.

Abstract

The invention relates to a timing belt, in particular to an automobile timing driving belt for oil immersion, which can be dipped in automobile engine oil for use. The automobile timing driving belt for the oil immersion comprises an annular belt body, a plurality of tooth parts and a core wire, wherein the tooth parts are formed at intervals along the inner surrounding surface of the belt body; the core wire is embedded along the periphery of the belt body; the outer surrounding surface of the belt body is provided with a back fabric layer; the inner surrounding surface of the belt body is provided with a tooth-shaped fabric layer covered above the tooth parts; and the back fabric layer and the tooth-shaped fabric layer are canvases subjected to dipping treatment by dipping mucilage of which the main ingredient is the same with the main ingredient (hydrogenated butadiene-acrylonitrile rubber) of the main body of the belt body. According to the automobile timing driving belt for the oil immersion, which is disclosed by the invention, the belt body is made of elastomer material with excellent oil resistance, the back of the belt body is provided with one layer of back fabric layer subjected to deoiling treatment, the middle of the belt body is provided with the core wire subjected to oil resistance treatment, and the inner surrounding surface of the belt body is provided with a plurality of tooth parts covered by the tooth-shaped fabric layer to serve as a transmission area.

Description

technical field [0001] The invention relates to a timing belt, in particular to an oil-immersed automobile timing transmission belt which can be immersed in automobile engine oil. Background technique [0002] With the continuous development of the automobile industry, the gradual implementation of high-efficiency and energy-saving requirements, the continuous development of the strategy of strengthening engine shrinkage, improving power and efficiency, reducing friction, reducing vehicle quality, and reducing costs is the key to the success of automobile manufacturers. element. Most of the current oil pumps of automobile diesel engines are driven by chains. This transmission system includes: sprockets, chains and tensioning devices, etc. High noise, troublesome maintenance and other shortcomings. Therefore, the automotive diesel engine needs a timing transmission system with simple structure, good reliability, more portable and energy-saving to meet the ever-growing energ...
