ZLY Helical Gear Speed Reducer speed reducer is a comparatively exact machine with aims of lowing revs but increasing torques. It can be classified into many kinds with different type and different use. ZLY Gear Speed Reducer has a good sealability and can adapt to different working environments. Furthermore, it can even work continuously in an erosive and humid environment with anti-erosion and long time reservation abilities. Key components of this speed reducer apply high-wearing materials and special heat treating. ZLY gear speed reducer are widely used in the fields of metallurgy, mines, hoisting, transportation, cement, architecture, chemical, textile, printing and dyeing, pharmaceutical and so on for their high precision, stable transmission, small volume, high bearing capacity and long life-span.

The Suitable Scope of ZLY Gear Speed Reducer:
1.The rotation of high speed shaft should not be more than 1500rpm;
2.The circumferential velocity of gear transmission should not be more than 20,/sec;
3.The temperature of work environment should be -40-45°C. If below 0°C, before start, the lubricating oil should be pre-heated to above 0°C. This speed reducer can be run in clockwise and counterclockwise direction.

Characteristics of ZLY Gear Speed Reducer:
1.The gear is made of high strength low carbon alloy steel through carburization and quenching. The hardness of tooth surface may reach to HRC58-62. All gear adapts NC tooth grinding process, high accuracy and good contact performance;
2.High transmission efficiency: single stage, more than 96.5%; double-stage, more than 93%; three-stage, more 90%;
3.Smooth and stable operation with a low noise;
4.Compact design, light weight, long life, high bearing capacity;
5.Easy to disassemble, inspect and assemble.
