What are the main factors affecting the price gap between hard tooth surface and soft tooth surface reducer

The price gap between hard tooth surface and soft tooth surface reducer is mainly affected by the following factors:

• Material Cost

• Gear material : The gears of the hard toothed reducer usually use high-quality alloy steel, such as 20CrMnMo, 20CrNiMo, etc. These materials have high strength, high wear resistance and good heat treatment performance. The gears of soft-tooth surface reducers are commonly made of ordinary steel such as 45 steel and 35SiMn, and the material price is relatively low.

• Box material : Because the hard-toothed reducer needs to withstand high load and impact force, the box is often forged with cast iron or high-strength cast steel. The box material of the soft-toothed reducer is generally ordinary cast iron, and the former has higher material costs.

• Manufacturing process

• Processing accuracy : The hard tooth surface reducer requires high-precision processing to ensure accuracy indicators such as tooth shape and tooth direction. Advanced processing equipment and precision processes, such as grinding teeth, shaving teeth, etc., are required to use high processing costs. The machining accuracy requirements for soft tooth surface reduction machine are relatively low, and conventional processes such as hobbing and tooth insertion are only used, so the processing cost is relatively low.

• Heat treatment process : The gears of the hard tooth surface reducer need to be heat treated by carburizing, quenching, nitriding, etc. to improve the hardness and wear resistance of the tooth surface. The heat treatment process is complex and the cost is high. The soft-tooth surface reducer is generally tempered or normalized, with a simple process and low cost.

• Production cycle : Due to the complex manufacturing process of the hard tooth surface reducer, it involves multiple processes and strict inspection, the production cycle is long, and the cost of capital and resources is high during the period, resulting in an increase in price. The production process of soft tooth surface reducer is simple, the production cycle is short, and the cost is relatively low.

• Performance and Application

• Load-bearing capacity : The hard toothed reducer has strong load-bearing capacity and is suitable for high-speed, heavy-load and harsh working conditions. In order to ensure high performance, better materials, more precise processes and stricter quality control are required during design and manufacturing, with higher costs and prices. The soft-tooth surface reducer has a low load capacity and is used in general working conditions with light load and low speed, and is cheaper.

• Service life : The hard tooth surface reducer has high hardness, good wear resistance, long service life, high cost-effectiveness for long-term use, but high initial purchase price. The soft-tooth surface reducer has a relatively short service life and is cheaper, making it more cost-effective for some short-term or low-demand application scenarios.
