Solution Description

 

S collection is one variety of Helical worm gearbox ,made as Modularization and higher-stainless forged iron case . It is blend of helical gear and worm equipment ,which with greater efficiency and strength than straightforward aluminum worm gearbox . Thanks to their excellent performance, these drives can be utilized in every single industrial sector and customized to specific torque and speed demands. The equipment ratios afforded by the helical-worm gear phase and the low sounds ranges during operation make these gearmotors ideal reduced-expense options for basic programs

 

Requirements:

one) Output velocity: .6~1,028r/min

2) Output torque: up to 4530N.m

three) Motor electrical power: .12~22kW

four) Mounted type: foot-mounted and flange-mounted mounting
