It can also include pressure block 45.Pressure block 45 is in circular platform type.There is coaxial through-hole, pressure block 45 passes through through-hole on pressure block 45
It is sleeved on pull rod 43, pressure block 45 is between threaded sleeve 44 and support plate 42, and the biggish end of area of pressure block 45
Facing towards support plate 42.The face area of threaded sleeve 44 is smaller, larger to the pressure of support plate 42, leads to the change of support plate 42
Shape, and it is easily damaged the surface of support plate 42.Pressure block 45 is in circular platform type, and a face area of pressure block 45 is larger, another
A face area is smaller, by the way that pressure block 45 is arranged, when installing lifting unit, makes the biggish end face pressure of the area of pressure block 45
In support plate 42, it can thus increase the forced area of support plate 42, to reduce the pressure on 42 surface of support plate, energy
Enough reduce the deformation of support plate 42, the also more difficult damage of the surface of support plate 42.When turning threaded sleeve 44, threaded sleeve
44 contact with the lesser end face of the area of pressure block 45, can when biggish abrasion occurs in the lesser end face of the area of pressure block 45
Only to replace pressure block 45, it is conducive to extend the service life of mounting tool.
Optionally, it is also provided with anti-rotating hole 43a on pull rod 43, anti-bull stick 431 can be inserted in anti-rotating hole 43a,
Since when turning threaded sleeve 44, pull rod 43 may be rotated together with threaded sleeve 44, just by setting anti-bull stick 431
It can prevent pull rod 43 from rotating by anti-bull stick 431 when turning threaded sleeve 44.In addition it is also possible to directly be pressed from both sides using tool
Pull rod 43 is handled, to prevent pull rod 43 from rotating.
As shown in figure 8, corresponding to each first screw hole 41a and each second screw hole 41b on bearing connecting plate 41 can distinguish
It is provided with counterbore 41c, and counterbore 41c is located at the surface towards support plate 42 of bearing connecting plate 41.Due to first bearing seat 121
Finite axial length, by the way that counterbore 41c, so that after connecting bearing connecting plate 41 with first bearing 31, bolt is arranged
Head is located in counterbore 41c without protruding from bearing connecting plate 41, has bearing connecting plate 41 and first bearing 31 bigger
Space is moved axially, maximum can be moved to bearing connecting plate 41 and be affixed with support plate 42.
Fig. 9 is a kind of structural schematic diagram of support plate provided in an embodiment of the present invention.As shown in figure 9, can in support plate 42
To be provided with multiple hollow out opening 42d.The weight that support plate 42 can be reduced by setting hollow out opening 42d, facilitates erector
The use of dress.
As shown in figure 8, can also be coaxially provided with annular locating lug boss 421 in support plate 42, annular locating lug boss 421 is located at
Support plate 42 towards on the surface of bearing connecting plate 41, the outer diameter of annular locating lug boss 421 with for installing first bearing 31
Bearing block internal diameter it is identical.In this way when support plate 42 to be installed in first bearing seat 121, cyclic annular convex can be passed through
Platform 421 positions, it is ensured that the female coaxial of support plate 42 and first bearing seat 121.
Similarly, multiple lightening holes can also be equipped on bearing connecting plate 41, so that the weight of bearing connecting plate 41 is reduced,
Facilitate the use of mounting tool.Multiple lightening holes can be along the equiangularly spaced arrangement of circumferential direction of bearing connecting plate 41, so that bearing
The Mass Distribution of connecting plate 41 is more uniform.
As shown in figure 8, being also provided with circular groove 42c in support plate 42.Circular groove 42c is located at the court of support plate 42
To on the surface of bearing connecting plate 41.Circular groove 42c and support plate 42 are coaxial, and the diameter of circular groove 42c is connect with bearing
The diameter of plate 41 is identical.By the way that circular groove 42c is arranged, so that when mounting tool to be installed in first bearing seat 121, it can
First to turn threaded sleeve 44, pull rod 43 is pulled, is located at bearing connecting plate 41 in circular groove 42c, then tightens screw thread again

Afterwards, threaded sleeve 44 is unclamped, bearing connecting plate 41 can be pushed into first bearing seat 121, can guarantee by pushing drawing rod 43
The female coaxial of bearing connecting plate 41 and first bearing seat 121 avoids bearing connecting plate 41 and is easy to appear skew during installation
And the problem of causing the inner wall of bearing connecting plate 41 and first bearing seat 121 to scrape.Support plate 42 is being installed to first
It on bearing block 121 and unclamps threaded sleeve 44, after threaded sleeve 44 is sent into first bearing seat 121, can use support
Bolt on multiple hollow outs opening 42d on plate 42, bearing connecting plate 41 is connect with first bearing 31.
Optionally, in support plate 42 multiple hollow outs opening 42d can along the equiangularly spaced arrangement of circumferential direction of support plate 42,
Not only the Mass Distribution of support plate 42 is more uniform in this way, but also convenient in each first screw hole 41a and the second screw hole 41b
Bolt.
Simple illustration is carried out to the installation process of lifting unit below.
Step 1: then assembling lifting unit removes the end cap of first bearing and the torque of gear shaft end face is arranged in
Sensor.
Step 2: lifting lifting unit using suspender, and first bearing is made to be inserted into first bearing seat, second bearing insertion second
Bearing block.
Step 3: bearing connecting plate is put into first bearing seat, and bearing connecting plate is connect with first bearing.
Step 4: support sleeve-board is connect on pull rod, and by support plate with first bearing seat.
Step 5: installation pulling force component pulls pull rod, adjustment lifting unit to required position by pulling force component.
Step 6: disassembly mounting tool reinstalls the end cap of torque sensor and first bearing.
It should be noted that the above installation process is only for example, the installation that can also have other different in actual installation
Form, and the installment work for different structure, installation process can also be different.Such as part mounting tool, Ke Yixian
Support plate is installed, then bearing connecting plate is connect with first bearing, is detailed in embodiment above.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
