465-90 tooth large pulley

With the continuous intensification of the competition in the gear industry, mergers and acquisitions and capital operations among large gear enterprises are becoming increasingly frequent. Domestic excellent gear manufacturers are paying more and more attention to the research on the industry market, especially the in-depth research on the development environment of enterprises and changes in customer demand trends. Because of this, a large number of domestic excellent gear brands have risen rapidly and gradually become the leaders in the gear industry!

474 large pulley

Belt pulley is a kind of disc hub part with relatively large relative size, and its manufacturing process is generally mainly casting and forging. Generally, the larger size is designed by casting method, and the material is generally cast iron (with good casting performance), but rarely cast steel (with poor casting performance of steel); Generally, the smaller size can be designed for forging, and the material is steel.

B 10 large pulley

A gear is a mechanical element with gears on the rim to continuously mesh and transmit motion and power. The application of gears in transmission has appeared very early.

B10 small pulley

The pulley is a wheel with equidistant axial teeth on the rim, which is generally made of steel, aluminum alloy, cast iron, brass, etc. The inner holes are in the form of round holes, D-shaped holes, tapered holes, etc. The surface treatment includes natural color oxidation, blackening, zinc plating, color zinc plating, high-frequency quenching, etc.

148 Counterweight

Counterweight is a weight used to increase its own weight to maintain balance.

148 Central pole

The central limit theorem is a kind of theorem in probability theory that discusses the asymptotic behavior of the partial sum distribution of random variables to the normal distribution. These theorems are the theoretical basis of mathematical statistics and error analysis, and point out the conditions under which a large number of random variables approximately follow the normal distribution.
