TIMING BELT

Two suppliers to the U.S. market are Bayer and Nippon Zeon. The estimated volume used in the United States is 500 700 t/yr. Hydrogenated nitrile mbber (HSN or HNBR) compounds compete with EKM, EVMQ, ECO, ACM, and high ACN content nitrile mbbers. Big applications include automotive timing belts, blowout preventors, drill pipe protectors, and numerous oil and fuel pump components. [Pg.232]

These are illustrated in Figure 3-18. Flat belts are used chiefly for conveyer belt systems rather than power transmission. I oothed (or timing) belt are generally used for control of critically timed rotating elements of a mechanical systems and are not used in power transmission application. The V section and the ribbed power belting systems are used exclusively for power transmission, and thus the discussion in this section will be confined to these categories of belting. [Pg.421]

Polyurethanes are used in many other applications, which we do not have room to discuss. These applications include paints, varnishes, adhesive binders for chipboard and plywood, hoses, timing belts, athletic tracks and playing surfaces, and the encapsulation of electrical components. [Pg.398]

Another part of the loop program ascertains how much solution is left in the pump. A voltage picked off a ten-turn potentiometer, which is coupled to the piston-drive screw with a timing belt, is fed to the analog-to-digital converter and is compared with the previously stored reading from the thumbwheel switch.

The drive shaft and bowl assembly are designed to function under water in the temperature bath. Supported above the water are the drive motor, I, timing belt and pulleys, H, the speed controller, J, and upper section of the chain drive housing, K. The use of a glass water bath and glass growth chamber permits the operator to see the crystal in motion. With submillimeter seeds, the initial rotation rate is several rpm and can be increased as needed. [Pg.774]

Acrylonitrile-butadiene rubber (NBR) may be reduced in [BMIMJfBFJ using the catalyst RuHCl(CO)(PCy3)2 [32] the saturated product is a very useful engineering polymer with applications in oil seals, timing belts, and hoses [33]. An enhanced reaction rate has been observed. The same reaction was reported in a range of haHde-free IL mixtures based on dialkylimidazolium cations and the tetrafluoro-borate anion [34]. [Pg.501]

This material showed excellent mechanical properties snch as Young s modulus, tensile strength, and heat distortion [80], and it was developed to be used in the automotive industry, specifically to be used in timing belts. However, these nanocomposites and some others have proved to be expensive and without market competitiveness over the years. Therefore they were not used for a long time in the industry [82].

The cost of nanofillers has been a discouraging factor but is being overcome as the scale of production and consumption increases. Toyota commercialised polyamide/nanoclay materials for timing belt covers in its cars ten years ago, and Unitika used similar materials in Mitsubishi engine parts. These early nanocomposites mostly proved too expensive for more widespread... [Pg.109]

The results of the measurements can be used for a quantitative test of the appropriateness of polymers in articles used dynamically as well as for the determination of the molecular mechanism, which generate the stress relaxation and the permanent deformation in polymers. This method can be used for a quantitative evaluation of polymers in articles used dynamically such as timing belts, engine moimts or seals. [Pg.32]

Several types of PEN- or PBN-reinforced belts and hoses, ranging from transmission belts to oil brake hoses, have been produced. Additional applications include timing belts, conveyer belts, high pressure hydraulic, steam, fuel, and coolant hoses, as well as polychain belt cord. [Pg.5788]
