Specific embodiment
The present invention is illustrated with reference to the accompanying drawing, shown in as shown in Figure 1, Figure 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, a kind of rotor
Axis inner spline housing structure, including shaft 1, the end of the shaft 1 are equipped with a word notch 101, and the inside of shaft 1 is equipped with ladder
Notch 102, washer 2 are arranged inside ladder notch 102, and the outside of washer 2 is abutted with the ladder notch 102 of shaft, the pad
Circle 2 is internally threaded notch 201, and the side of washer 2 is equipped with inner spline housing 3, and the inner spline housing 3 includes circumferential part 301, institute
Outer dimension and the ladder notch 102 for stating circumferential part 301 are consistent, and the circumferential part 301 is abutted with washer 2, and inner spline housing also wraps
Key set portion 302 is included, the outer dimension in key set portion 302 and a word notch 101 of roller end are consistent, key set portion 302
Inside is equipped with spline 302A.
The shaft 1 is additionally provided with bearing 4, and the bearing 4 is by covering 5 axial restraint of the first retaining ring in shaft, interior flower
Key set 3 is by covering 6 axial restraint of the second retaining ring in shaft.
The present invention further discloses a kind of for dismantling the tooling of above-mentioned inner spline housing: being equipped with percussion hammer 7, one end of percussion hammer 7
It is thread segment 701 identical with the screw thread notch size of bead interior, the other end of the percussion hammer 7 is circumferential size maximum,
Sleeve 8 is additionally provided at the circumference of the percussion hammer.
Installation process of the invention is: first loading onto inner spline housing and washer sets；Inner spline housing and axis are assembled again, by
Then slight interference cooperates, and practical wooden mallet gently squeezes into spline housing, pays attention to alignment cavities, squeezes into place；Again by bearing hot charging to axis
On, it is installed in place；Then first retaining ring is installed at the retaining ring ditch of bearing, prevents bearing axial float, finally install the
Two retaining rings prevent the axial float of inner spline housing at the retaining ring ditch in outside.
Disassembly process of the invention is: if spline wear, damaging, has screw hole on the washer inside spline housing, will first consolidate
The retaining ring for determining spline housing is laid down, and then using the tooling of disassembly inner spline housing, the threaded portion of front end is screwed into the screw thread of washer
Kong Zhong ensure that is be threaded into smoothly completes since washer and spline are cased with thread groove cooperation, after being screwed into washer, use
Sleeve in tooling hits the rear end of tooling repeatedly, is displaced outwardly by impact force band washer, finally dismantles down inner spline housing
Come.
