Development trend of geared motors
In the 1970s and 1980s, there was a great development of geared motor technology in the world
and it was closely integrated with the development of the new technological revolution. The development trend of general-purpose geared motors is as follows:
1, high level, high performance: cylindrical gears are generally carburized and quenched, ground teeth, bearing capacity increased by more than 4 times, small size, light weight, low noise, high efficiency and high reliability;
2, building block combination design: the basic parameters of the number of priorities, size specifications neat, universal and interchangeable parts, the series is easy to expand and renovate the pattern, conducive to the organization of mass production and reduce costs;
3, type diversification, variant design: get rid of the traditional single base mounting, adding a hollow shaft suspension, floating support base, motor and reducer integrated coupling, multi-directional mounting surface and other different types, to expand the scope of use.
Promote the main factors to improve the level of reducer are:
1, the increasing perfection of theoretical knowledge, closer to the actual (such as gear strength calculation method, repair technology, deformation calculation, optimization design method, tooth root smooth transition, new structure, etc.);
2, the use of good materials, generally use a variety of high-quality alloy steel forgings, materials and heat treatment quality control level;
3、Structure design is more reasonable;
4, machining accuracy increased to ISO5-6 level;
5, bearing quality and life improved;
6. Improvement of lubricating oil quality.
