The development trend of reducer
In the 1970s and 1980s, the reducer technology in the world has made great progress, and it is closely integrated with the development of the new technology revolution. The development trend of general reducer is as follows:
1. High level and high performance: Cylindrical gears are generally carburized, quenched and ground, and the bearing capacity is increased by more than 4 times, with small size, light weight, low noise, high efficiency and high reliability;
2. Building block combination design: the basic parameters adopt the priority number, the dimensions are neat, the parts are versatile and interchangeable, the series is easy to expand and pattern renovation, which is conducive to organizing mass production and reducing costs;
3. Diversified types and many variant designs: It got rid of the traditional single base installation method, and added different types such as hollow shaft suspension, floating support base, integrated connection of motor and reducer, and multi-directional installation surface to expand the scope of use. .
The main factors that promote the improvement of the reducer level are:
1. The theoretical knowledge is becoming more and more perfect and closer to reality (such as gear strength calculation method, modification technology, deformation calculation, optimization design method, smooth transition of tooth root, new structure, etc.);
2. Use good materials, generally use various high-quality alloy steel forgings, and improve the quality control level of materials and heat treatment;
3. The structure design is more reasonable;
4. The machining accuracy is improved to ISO5-6 level;
5. The bearing quality and life are improved;
6. The quality of lubricating oil is improved.
