Details


The timing belt is made of three main materials: neoprene, glass fiber thread and elastic nylon cloth. It is a special rubber transmission belt used for various mechanical transmissions. It is the use of gear and gear with the anastomosis of transmission, and thus both gear transmission, chain transmission and belt transmission of the three integrated characteristics.
The use of rubber synchronous belt drive has the following advantages:
Ensure synchronous transmission without slip between transmission wheels
The transmission speed ratio can reach 10, and the transmission speed can reach 40 M/S
The transmission power can be from a few watts to the upper kilowatt
The transmission structure is simple and light, and does not require lubrication
No need for large initial tension, small shaft load
Low running noise
Simple maintenance, easy replacement, etc.

car synchronous belt raw materials:

 

Using imported high-quality synthetic neoprene (or hydrogenated nitrile rubber) as the main raw material, with a variety of different uses of accessories; skeleton material for imported high-quality glass fiber rope; toothed surface with nylon 66 high elastic cloth to do protection, and in strict accordance with the technical specifications of the production. It has the characteristics of clean appearance, full tooth profile, long service life and low noise.

 

Characteristics of automobile synchronous belt

 

neoprene synchronous belt:

 

Good heat resistance-can be used for a long time in the working environment of 120 ℃ and below;

 

Good aging resistance-especially ozone resistance;

 

Good chemical stability: in addition to strong oxidizing acid, resistance to general chemical erosion;

 

Good fire resistance and water resistance;

 

hydrogenated nitrile rubber belt:

 

Excellent oil resistance-with very low oil expansion resistance, higher oil resistance;

 

Good durability-dynamic performance is better than chloroprene rubber synchronous belt, which is the preferred transmission belt for medium and high-grade cars;

 

Excellent wear resistance-the amount of wear is smaller than the neoprene timing belt, which reduces noise and effectively extends the service life of the timing belt;

 

Application of hydrogenated nitrile rubber in automobile synchronous belt:

 

Due to the higher and higher requirements for energy saving, environmental protection, comfort, and safety of modern automobiles, the entire engine room has a complex and compact structure, and the working temperature is relatively high. The rubber parts should have high temperature resistance. With the improvement of engine lubrication technology, new additives are used in lubricating oil, so higher requirements are put forward for the oil resistance of rubber parts in engines. On the other hand, the longer the maintenance period, the durability of the rubber parts is also getting higher and higher. Modern automobiles require rubber parts to be able to withstand -40°C ~ 150°C under certain oil-resistant conditions. The transmission belt is an important rubber part of the automobile, including the timing belt for the OHC engine, the automobile V belt for the auxiliary transmission of the automobile And the V-ribbed belt, and the newly developed variable V-belt for the continuously variable transmission mechanism (CTV). Since the publication of the first HNBR patent in 1975, HNBR has gradually developed into the preferred standard elastomer material for the production of automotive timing belts in the world today.

 

The specific requirements of modern cars for synchronous belts:

 

  

The durability is increased by more than 1.5 times; the bandwidth is reduced by 20%; the heat resistance is increased by 10 ℃. The synchronous belt is a composite of rubber, fiber tensile body (glass fiber or aramid) and nylon tooth cloth. The fatigue life and water resistance of the synchronous belt made of HNBR are much better than those made of neoprene and chlorosulfonated polyethylene.
