1. Product description The oil tank or circulating lubrication should be used for the reducers. All the reducers are produced in accordance of the former one. But the circulating lubrication should best be adopted under the circumstances of high ambient temperature, large power, high speed or continuous running, so to decrease oil temperature and make best use of the reducer's load-bearing capacity, we can supply circulating lubrication unit. When the reducer works in lower ambient temperature, the oil temperature should higher than 0â??. 2. Characteristics Model Single-stage: ZDY model, Double-stage:ZLY model, Three-stage:ZSY model, Four-stage:ZFY model Technical parameter Transmission rate: single-stage 1.25~6.3, double-stage 6.3~20, three-stage 22.4~100. 3. Application area Conical Cylindrical Gear Reducers are mainly applied to belt conveyer and some other transportation machines and the speed reducer can also be used in other general mechanical transmission organs of metallurgy, mining, chemical, coal, construction material, textile, oil /petroleum and so on. 4.Our service Professional in transmission systematize solution & production based here, High quality and best service is our culture.We accept sample order to confirm quality.
