Adjustable spacing multi-shaft integrated air inflation shaft

Abstract

The utility model relates to the technical field of gas expansion shaft, specifically disclose a multi -shaft integral type gas expansion shaft of adjustable spacing, including the main shaft body, one end outer surface fixedly connected with first transmission gear, the side of first transmission gear is connected with second transmission gear, the other end outer surface fixedly connected with support frame of main shaft body, the surface fixedly connected with drive motor of support frame, the output fixedly connected with adjusting gear of drive motor. This multi -shaft integral type gas expansion shaft of adjustable spacing, through drive motor drives adjusting gear to rotate, adjusting gear and linkage gear mesh, make adjusting screw rod rotate, and then drive the first support column of L type and circumferential array setting slides along main shaft body, accurate adjustment position of limit sub -shaft, this makes gas expansion shaft can adapt to the coiled material inner hole of different spacing, compared with the gas expansion shaft of small telescopic range of traditional key strip, more various coiled material specification can be supported, greatly improve practicality.
