The utility model provides a screw wing type water meter movement, which belongs to the measuring technical field. The utility model solves the problem of poor universality of the existing screw wing type water meter movement. The spiral wing type water meter machine, which comprises a bracket, a worm gear component and ring magnet; stent positioning screw wing; bracket positioning a drive shaft and fixed with a supporting shaft, the drive shaft end is connected by a worm gear assembly and screw wing, the drive shafts are fixed at the other end the driving gear shaft, positioning and supporting the center wheel is engaged with the driving gear and the ring magnet and the center wheel is fixedly connected. The Woltman meter movement through the design of the driving gear and the gear ratio between the center, to achieve different types of movement make ring magnet at the same speed output; thus movement of different types can be matched with the same counter.
