Description

MC nylon elevator drive wheel convenient to change Technical Field The utility model relates to the technical field of elevators, in particular to an MC nylon elevator driving wheel convenient to replace. Background The elevator is a permanent transportation device which is used for serving a plurality of specific floors in a building and is operated on at least two rows of rigid rail motion vertical to a horizontal plane or inclined at an angle smaller than fifteen degrees with a plumb line, chinese patent application publication No. CN215828129U discloses a friction nylon elevator driving wheel which comprises a rotating shaft, wherein a driving device is movably arranged outside the rotating shaft and comprises a vane, a fixing frame, fixing screws, a first screw, a first nut and a second screw, the vane is movably arranged outside the rotating shaft, the right side of the vane is in threaded connection with the fixing frame, the right side of the fixing frame is in threaded connection with the fixing screws with four angles, and the first screw with four angles is movably arranged inside the vane.
