1641；After the baffle ring 160 is fixed on the axle sleeve 130, screw is prevented through the locking through hole 1631 with described
Loose threaded hole (being blocked in figure) connection, tightens the screw between locking through hole 1631 and the checknut hole so that described
The width of seam 162 reduces, and destroys the spacing of internal thread 161 so that screw thread is not easy to loosen, and reaches locking effect.
The middle part of the axle sleeve 130 is from the end face of the fastening mounting flange 131 on the direction of the fixed end cap 134
Extend to form fastener hole 136, the extending direction of the fastener hole 136 axial consistent, fastener hole with the bearing 120
136 side is annular inner conical surface, i.e., from the fastening mounting flange 131 to the fixed end cap 134, the fastener hole 136
Diameter gradually linearly diminish；Copper sheathing 170 is equipped with the fastener hole 136, the outside of copper sheathing 170 is equipped with annular outer cone
Face 171, the inner side of copper sheathing 170 are equipped with axle mounting hole 172, and the big end 174 of the copper sheathing 170 is equipped with external screw thread 173, institute
State and clamp flange 180 is equipped with the outside of the big end of copper sheathing 170, the inner side of clamp flange 180 is equipped with internal thread 181, the fastening
Flange 180 is connected by internal thread 181 and external screw thread 173 with the copper sheathing 170；The clamp flange 180 is equipped with fixed logical
Hole 182, the position that the fixed hole 182 is corresponded on the fastening mounting flange 131 are equipped with fastening thread hole 137, screw
It is connected through the fixed hole 182 with the fastening thread hole 137, so that the clamp flange 180 and the fastening
131 distance of mounting flange diminishes；Axle 200 is inserted into the axle mounting hole 172 during use, the surface of the axle 200
Coordinate with the side of the axle mounting hole 172, then axle 200 and copper sheathing 170 are inserted into the fastener hole 136 together,
The annular male cone (strobilus masculinus) 171 of the copper sheathing 170 is bonded with the annular inner conical surface of the fastener hole 136；Further, by tightening
State clamp flange 180 and it is described fastening mounting flange 131 between screw so that the annular inner conical surface of the fastener hole 136 into
The one step extruding annular male cone (strobilus masculinus) 171 so that the copper sheathing 170 deforms, so as to extrude the axle 200 so that the axis
Set 130, copper sheathing 170 and axle 200 fit closely, and achieve a fixed connection.Heretofore described annular male cone (strobilus masculinus) and the annular
The taper of inner conical surface uses 1: 20.
As shown in fig. 6, on the copper sheathing 170 along the axial direction of the copper sheathing 170 from the end face of the big end 174 to
The extension of small end 175 of the copper sheathing 170 is provided with the first sealing 176, and the end 1761 of first sealing 176 is located at the small end
Between 175 end face and the end face of the big end 174；Along the axial direction of the copper sheathing 170 from described on the copper sheathing 170
Big end 174 extension of the end face of small end 175 to the copper sheathing 170 is provided with the second sealing 177, the end of second sealing 177
(being blocked, can refer to the end 1761 of the first sealing 176) is located at the end face of the small end 175 and the end face of the big end 174
Between；First sealing 176 and second sealing 177 can be a plurality of along being provided at circumferentially spaced for the copper sheathing 170, generally
Ground, can symmetrically be oppositely arranged first sealing 176 and second sealing 177 in the outside of copper sheathing 170.Described in extruding
During copper sheathing 170, first sealing 176 and second sealing 177 can accommodate the deformation of the copper sheathing 170 so that copper
The surface and the surface of the axle 200 of the mounting hole 172 of set 170 fit closely.On the other hand, first sealing 176 passes through
The external screw thread 173 has been worn, when copper sheathing 170 deforms, has destroyed the gap between screw thread, the effect with locking thread, makes
170 clamp flange 180 of copper sheathing connect it is relatively reliable, avoid cause when axle 200 rotate at a high speed clamp flange 180 and
Loosened between the copper sheathing 170.The small end of the copper sheathing 170 extends inwardly to form axle positioning convex platform 178 along radial direction,
The axle 200 is resisted against the axle when penetrating in the axle mounting hole 172, by the end face of the axle 200 and positions
On boss 178, in this way, just can perceive whether copper sheathing 170 is installed in place by simply tapping copper sheathing 170, avoid using meat
Eye observation, reduces installation effectiveness.The radial direction of the radial dimension of the axle mounting hole 172 of copper sheathing 170 and axle 200 in the present invention
Size is consistent, i.e., a diameter of 130mm, consistent with the radial dimension of standard axle so that supporting structure 100 of the invention can be direct
For with standard vehicle axis connection, can directly embody truth.
Run through as shown in figure 5, being equipped with the fixation end cap 134 of the axle sleeve 130 along the axial direction of the axle sleeve 130
Stepped hole 1341, in use, the end face of the axle 200 is equipped with fixing screwed hole, the position of the fixing screwed hole with
The position correspondence of the stepped hole 1341, in extruding copper sheathing 170 so that axle sleeve 130, copper sheathing 170 fit closely it with axle 200
Afterwards, also it is connected using fixing screws through the stepped hole 1341 with the fixing screwed hole 210 on 200 end face of axle,
The fixing screws are finally tightened, add connection reliability, when copper sheathing 170 cannot meet to transmit huge moment of torsion, pass through institute
State fixing screws and carry out moment of torsion transmission, prevent test failure；Using stepped hole 1341, the head of fixing screws can be embedded in described
In fixed end cap 134, prevent from influencing the installation of follow-up parts；The internal diameter of the axle positioning convex platform 178, which is more than, to be used to connect
