124 and adjoin one second operating side 126 in the second outer cylindrical body portion 124, the second inner cylinder portion 122 has thread surface.Fig. 4
For Fig. 3 sectional view of the frame 100 along line A-A.As shown in figure 4, rotating basis 102 its have a screwed hole 134 and a hole
132.In the present embodiment, the screwed hole 134 of rotating basis 102 is located at left side, and hole 132 is located at right side, therefore left side is regulation
Side.Base 104 has one first column 140 and one second column 142, and the first column 140 and the second column 142 have one respectively
First mounting hole 130 and one second mounting hole 131.Frame 100 also includes a clutch shaft bearing 128 and a second bearing 129.First
Bearing 128 and second bearing 129 can using deep groove ball bearing or with bear simultaneously the axially and radially bearing of load or
Bearing group, clearance scope can be in 0.2~0.5mm.
When installing rotating basis 102, second bearing 129 is first sheathed on to the second outer cylindrical body portion of the second sloping shaft 108
124 are placed in the second mounting hole 131 of base 104, rotate the second operating side 126 of the second sloping shaft 108 so that in second
Trunk portion 122 screws in the screwed hole 134 of rotating basis 102, and leaves second bearing 129 and the second column 142 of base 104
Gap.
The first outer cylindrical body portion 114 that clutch shaft bearing 128 is sheathed on into the first sloping shaft 106 again is placed in the of base 104
In one mounting hole 130, the first inner cylinder portion 112 of the first sloping shaft 106 is passed through to the hole 132 of rotating basis 102, by first axle
The first column 140 for holding 128 respect theretos 104 is fixed, and fixes the first operating side 118 and in the side of rotating basis 102 by a nut
136 are anchored on the end of thread 116.The first sloping shaft 106 is being fastened, should ensure that the second sloping shaft 108 is in free state, bearing
Clearance is between 0.2~0.3mm.In the present embodiment, clutch shaft bearing 128 has mounting hole, and it is placed on consolidating for the first column 140
Determine screw, clutch shaft bearing 128 can be fixed on the first column 140 by the cooperation of nut and fixing screws.
Fix after the first sloping shaft 106, dial gauge is placed on to the end of mounted first sloping shaft 106, zero setting.
Finally the second column 142 of the respect thereto 104 of second bearing 129 is fixed and second is fastened with another nut 136
Inner cylinder portion 122, and make the axial displacement of the first sloping shaft 106 be zero.In the present embodiment, second bearing 129, which has, installs
Hole, it is placed on the fixing screws of the second column 142, can be fixed on second bearing 129 by the cooperation of nut and fixing screws
Second column 142.The depth of screwed hole 134 is screwed in by adjusting the second inner cylinder portion 122, you can realize the fine setting of X-direction,
So as to change the distance of base 104 and rotating basis 102 in regulation side, the machining deviation of rotating basis 102 and base 104 is eliminated
With size matching problem caused by the error of deformation so that ensure bearing be in normal working condition.
During the second sloping shaft 108 is fixed, if it find that dial gauge is not at zero, for example opened by conventional tool
Mouth is pulled, and adjusts the second operating side 126 of the second sloping shaft 108, controls the state of internal stress, so that dial gauge is in zero again
Position.The numerical value of dial gauge will be checked after the nut of tightening fixation second bearing 129 and after the nut of the second sloping shaft 108 of fastening
Dispaly state.
To make the second sloping shaft 108 during installation rotating basis 102 be in transitory state, rotating basis 102 can pass through volume
Outer support or lifting.
To limit the axial location of clutch shaft bearing 128 and second bearing 129, make bearing outer ring can only around axial rotation, the
One sloping shaft 106 has one first shaft shoulder 110, and it is occupy between the first inner cylinder portion 112 and the first outer cylindrical body portion 114, and second
Sloping shaft 108 has one second shaft shoulder 120, and it is occupy between the second inner cylinder portion 122 and the second outer cylindrical body portion 124.First axle
128 outer ring is held against first shaft shoulder 110, inner ring is blocked with a clamp ring 138, the outer ring of second bearing 129 is against the second axle
Shoulder 120, inner ring is blocked with another clamp ring 138.Clamp ring can use standard component, and it carries holding screw, for by clamp ring
It is stuck.
One or two in first operating side 118 and the second operating side 126 can be outer-hexagonal structure, convenient use mark
Quasi- instrument such as open-end wrench is adjusted.
In addition to threaded connection, the form such as the first sloping shaft 106 and the second sloping shaft 108 can also be locked by eccentric ring
Realize axially position.
In the present embodiment, the hole 132 of rotating basis 102 is a through hole, the first inner cylinder portion of the first sloping shaft 106
112 be a polished rod, therefore, and only the second sloping shaft 108 is adjustable.In other embodiments, the hole 132 of rotating basis 102 can also
It is a screwed hole, correspondingly, also there is thread surface in the first inner cylinder portion 112 of the first sloping shaft 106, therefore, the first sloping shaft
106 and second sloping shaft 108 it is adjustable.
