Slewing ring slewing drive S-II-O-1091-MC

spur gear drive to servo positioners, requiring the rotation accuracy ≤0.01°. Due to the servo motor customers have special requirements, therefore required the starting torque of the precision gear type slewing drive was pretty small. After receiving customers’ requirements, the design team of Unique Transmission decided to use negative clearance slewing rings. The gears of the slewing ring and the gears of the transmission pinion were grinded after quenching, then the gear accuracy had reached 6 grade, the gear runout of the finished slewing ring was within 0.05mm. Only in this way can ensure customers’ final requirements, through reasonable process arrangements and strict quality control, the final finished slewing ring has a tooth runout of 0.05mm and an end face runout of 0.03mm, the pinion fully meets the requirements of 6 grade to lay a solid foundation for customers to use high-precision gear type rotary drives on servo positioners.
