LPY, LSY series are vertical parallel shaft 2,3 stage hardened gear reducer of the involute curve principle drive; it is thehardened gear reducer which has medium and lower output speed .and big output torque so that it can be suitable forthe long shaft mixing of the high efficiency big loading kettle, the advantages of the LPY , LSY series is not only theimprovement of the performance ,also for the reason of the application , LPY. LSY will lengthen the lifetime of thebearing , the layout of the larger bearing spacing , the best oil recycle and cooling system to show the real high-loadingdesign. There is a flexible coupling between the motor and the reducer . it can stable operating ,and lower noise,convenient disassembly. This series of reducer are isomorphic to the heat balance allowable power verification, ifrequest the additional cooling system. Pls do inotification when make the order .In order to solve the mass settlement which will make re-start difficultly when the equipment shut down , so we use thehand-runing gear for solve this problem , it has simple structure , and handle easily and safety. When let go it will stopand not effect the start of the motor.
