Product Description
1, the classification of the reducer range of applications
QY series reducer including QYS type (three-wheel) and QYD type (base) two cranes with Hardened reducer. Three, four and thirty-four bound three
This reducer is mainly used for the various agencies of the crane can also be used for the transmission of transportation, metallurgy, mining, chemical and light industry machinery and equipment. Their working conditions:
1) gear circumferential speed of not more than 20 minutes;
2) high-speed shaft speed is less than 1500r/min;
3) Operating ambient temperature -40 ° C - +45 ° C;
4) can be both positive and negative to the operation.
2, Features:
Consider the crane agencies work characteristics, the range of gear ratios, further improve product performance, fewer specifications to meet the requirements of various users, which is characterized by:
1) high carrying capacity. The gears are made of carburizing, quenching, grinding teeth, a substantial increase in carrying capacity than the quenched hobbing soft tooth surface and hardened gear reducer.
2) small size and light weight. Compared with the soft tooth surface and hardened reducer. The same carrying capacity reducer considerable frame size can be reduced by 2-4.
3) high efficiency, low noise, small vibration. Grinding teeth to improve the accuracy class, gear repair edge, the overall efficiency of each stage gear 0.98, significantly reducing vibration and noise.
4) the use of multi-level number, to reduce the single-stage ratio. The opened center distance, reduce reducer Overall height, to meet the requirements of the agencies of the crane; Reducer nominal maximum transmission ratio of 400 to meet the requirements of the slow crane.
5) three-wheel reducer, vertical, horizontal, or even deflection angle installation, convenient and flexible.
6) 34 combined type (that is the three assembly type, four transmission ratio) slow cranes universal premise of the series reducer.
5, shaft type
High-speed shaft and a cylindrical shaft, flat key connection.
The low-speed shaft end, there are three types:
A P-type: Cylindrical shaft extension, flat key, one-touch connection;
H-type: Cylindrical shaft extension, involute spline connection;
C C type: Gear shaft (the only nominal center distance of 180-560mm reducer gear shaft end).
Tag example:
1) Nominal center distance a1 = 315. The nominal transmission ratio i = 56. Assembly type is m, the low-speed shaft end spline shaft extension crane
Three three-wheel hardened reducer.
Marked as: Reducer QY3S315-56 III H.
2) the nominal center distance a1 = 450, nominal transmission ratio i = 280 assembly type, low-speed wheel gear shaft end. Crane
Base hardened four reducer.
Marked as: Reducer QY4D450-280 II C.
