Summary

ZLY series (two-stage) hard tooth surface cylindrical gear reducer is produced in accordance with JB / t8853-2001 standard. The product has been optimized and arranged with parallel shafts. Widely used in mining, metallurgy, lifting, transportation, cement, construction, ignition, as long as, textile, chemical and other industries.

Performance characteristics

• The gears are all made of high quality low carbon alloy steel by normalizing and carburizing. The hardness of the gears reaches hr58-62. The gears are all grinded with high precision and good contact.
• High transmission efficiency
• Small size, light weight, high precision, large bearing capacity and long service life.
• High reliability, stable operation and low noise.
• The main parameters, such as center distance and transmission ratio, have been optimized, and the main parts have good interchangeability, easy disassembly and installation.
• Generally, it adopts oil pool lubrication and natural cooling. When the thermal power is insufficient, circulating oil lubrication or fan can be used for cooling.

 Working conditions

• The speed of high-speed shaft of reducer shall not be greater than 1500r / min.
• The peripheral speed of gear transmission of reducer is not more than 20 m / S
• When the working temperature of the reducer is - 40 ~ 50 ℃, and it is lower than 0 ℃, the lubricating oil shall be preheated before starting.
• The reducer can operate in both positive and negative directions.
