Document Type and Number:
WIPO Patent Application WO/2021/190023
Kind Code:
A1
Abstract:
Disclosed are a balance shaft sleeve decomposition assembly (100), and a balance shaft sleeve decomposition method. The balance shaft sleeve decomposition assembly (100) comprises: an extension section (1) used for being fastened to the axial tail end of a rotation shaft (10) so as to extend the axial length of the rotation shaft (10); a top plate (2) axially positioned on the extension section (1) and provided with a plurality of mounting holes (22); and a plurality of decomposition screws (3) evenly distributed in the circumferential direction of the top plate (2), wherein the plurality of decomposition screws (3) penetrate the plurality of mounting holes (22) correspondingly and are in threaded connection with and fastened to at least some of a plurality of balancing machine reserved connectors (203), each decomposition screw (3) is provided with a first threaded section (31), and at least one part of the first threaded section (31) is in threaded connection with and fastened to the balancing machine reserved connectors (203); and extrusion members (4) fixedly connected to the decomposition screws (3), wherein the extrusion members can apply an axial extrusion force (F1) to the top plate (2) and are subjected to a counter-acting force (F2) of the extrusion force (F1), and the counter-acting force (F2) makes a balance shaft sleeve (20) separate from the rotation shaft (10). The decomposition assembly (100) has a good universality, and makes the balance shaft sleeve (20) simple in decomposition operation and easy to decompose.
