Reducer in the mill side and motor side load distribution is different.

The contact surface between each box flange are sealed to seal paste, every time the re opened fold should re apply, and to prevent leakage. Cover allwith that observation. In order to give full play to the performance of reducer, long-term safety operation, the speed reducer is equipped with a lubricating three pump station, one for the hot oil pump, two sets of cold oil can be standby for each other; the lubricating oil viscosity largerlubrication. The main characteristics of thin oil station three oil pumps,technical characteristics of three branch of speed reducer of gear. Practice has proved that, CrNIMo steel manufacturing material gear best, on the soft,hard and hard tooth face Ken wheels are used. Hardened gear Germany were adopted 17CrNIM Yong steel, such as Handan cement factory introduced the Thyssen (SHYSSEN) TGW type double shunt side shaft type gear reducer, Huaihai cement factory introduction fee rand (FLENDER), planetary reducer gear, thecarbon content of steel is low (average 0.17%), heat processing must therefore adopt surface carburizing and quenching. Gear ratio gearperformance are superior to the general overall hardening, so now the high performance speed reducer gear adopt measures gear high-frequency surface hardening and surface carburizing quenching surface hardening.

Characteristic of tooth profile gear reducer in operation, low output load distribution character of gear. Reducer in the mill side and motor side load distribution is different. Caused by uneven distribution factor andproportional loading are: 30% 20% torsion; bending; bearing clearance 20% box deformation; 10%. In order to ensure the uniform load distribution, according to the specific circumstances of each tooth is different, should adoptdifferent modification techniques (such as tooth long end trimming, addendum modification and the helix angle modification etc.). Obtain load distributionmodification is greatly improved, by reducing the tooth width loadcoefficient K printing can clearly see this point. The design for the design of precision reducer, stiffness critical case.
