Product diagram
Precision worm gear transmission and rotating shaft system design, high adjustment accuracy, small air return, and the air return clearance caused by use can be adjusted by the air return elimination structure. The end jump and eccentricity of the rotating table are low, and the rotating motion is stable. The central through hole of the rotary table is strictly coaxial with the rotary center, and the central aperture is strictly matched with the tolerance limit, which is convenient for precise positioning. The induction motor and worm are connected through high-quality elastic coupling, with synchronous transmission and depolarization performance number, so as to eliminate empty return and form and position errors.
It can provide electrical accessories for stepping and servo, provide relevant technical support, and accept product restructuring and customization.
