Factory engineering machinery excavator loader Cast iron 428 planetary gearbox for power transmission
Features of construction
The assembly of the clutch is complex, taking the reverse clutch as an example, including the assembly of gear ring components, seals, return springs, friction plates and other steps, and the assembly accuracy and order have strict requirements. For example, when the friction plate is assembled, there are 6 active plates (sintered powder metallurgy material) and 5 slave plates (spring steel material and one side has 0.1 mm of concave), and attention should be paid to the details such as the convex face of the slave plate towards the piston when assembling.
Assembly assembly involves the installation of multiple components and components, such as bearing end caps, each clutch assembly, box covers, etc., and the axial clearance of each bearing needs to be adjusted to ensure the normal operation of the transmission.
Scope of application:
Suitable for Liugong, Xiagong, Longgong, Linggong and other brands of loaders, forklifts. Different construction machinery and equipment have different requirements for the performance and adaptability of the gearbox, and the gearbox has been designed and optimized to meet the needs of these equipment in various working conditions.
