Summarization
This product is an outer meshed involute helical tooth cylindrical gear speed reducer.
It is widely applied to the fields of metallurgy, mines, hoisting, transportation, cement, architecture, chemical, textile, printing and dyeing, pharmaceutical, etc.
The suitable scope of speed reducer is as follows:
1.The rotation of high speed shaft should not be more than ***0rpm;
2.The circumferential velocity of gear transmission should not be more than *0,/sec;
3.The temperature of work environment should be *****5℃. If below 0℃, before start, the lubricating oil should be pre-heated to above 0℃. This speed reducer can be run at clockwise and counterclockwise direction.

Characteristics:
1.The gear is made of high strength low carbon alloy steel through carburization and quenching. The hardness of tooth surface may reach to HRC****2. All gear adapts NC tooth grinding process, high in accuracy and good in contact performance
2.High in transmission efficiency: single stage, more than *6.5%; double-stage, more than *3%; three-stage, more *0%;
3.Smooth and stable in run, low noise;
4.Compact, light, long life, high bearing capacity;
5.Easy to disassemble, inspect and assemble.
