Papermaking machine roll shaft joint device

Abstract

A papermaking machine roll shaft joint device comprises a bottom plate and further comprises fixing seats, and a connecting pipe is arranged between the two fixing seats. end fixing pieces are arranged at the two ends of the connecting pipe; a clamping piece is arranged on the upper side of the fixing seat and connected to the outer wall of the connecting pipe; an auxiliary fixing frame is arranged on the upper side of the fixing seat and connected to the side wall of the clamping piece; extrusion pieces are arranged at the upper ends of the two clamping pieces and are connected to the upper side of the connecting pipe; the end fixing piece comprises an outer jacking pipe, and a first protrusion is arranged at one end of the outer jacking pipe. the inner jacking pipe is arranged in an inner cavity of the outer jacking pipe; a first screw rod is screwed on the outer jacking pipe and the inner jacking pipe; a first extrusion block is convexly arranged on the outer wall of the other end of the outer jacking pipe; a second screw rod is screwed on the first extrusion block; a first adjusting seat is arranged on the second screw rod; a first end cover is arranged at the end part of the outer jacking pipe; a second buffer seat is arranged at the edge of the first end cover; and a joint device can axially position the roll shaft of the paper machine.

Description

technical field [0001] The invention relates to mechanical parts, in particular to a paper machine roll shaft joint device. Background technique [0002] The paper machine roll shaft joint device, as the name suggests, is to use the joint device to axially connect the paper machine roll shaft and other transmission shafts to transmit power. When the joint device is used to connect the two rotating shafts, due to the vibration in the longitudinal direction during the mechanical transmission process, the rotating shafts will also move in the axial direction at the same time. When there is axial movement of the rotating shaft, it is easy to cause mechanical connection failure and affect the progress of machining. [0003] However, the existing paper machine roll joint device simply connects two rotating shafts, does not provide an effective structure for axial positioning of the rotating shafts, and cannot effectively control the axial movement of the rotating shafts.
