Embodiment
As illustrated, a kind of shaft-end positioning structure for vertical spin elevator.
It include being used for wear-resisting watt of seat 2 being fixedly connected with the helical axis 11 of vertical spin elevator and for be located at it is vertical
The locating shaft 1 that the feeder housing 12 of straight screw elevator shell is fixedly connected, locating shaft 1, which includes coordinating with wear-resisting watt of seat 2, pacifies
The positioning section 101 of dress and the flange linkage section 102 of connection feeder housing 12；Wear-resisting watt of seat 2 is by being located at the evagination of its underpart
Edge 202 is attached with helical axis 11 using bolt.
Directly coordinate peace with positioning section 101 circumferentially arranged with one close to the position of lower end on the inwall of wear-resisting watt of seat 2
The annular protrusion 203 of dress.Position between positioning section 101 and wear-resisting watt of seat 2 above annular protrusion 203 is provided with wear-resisting shaft
