Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.
The present embodiment provides a kind of for speed changer by the fast accurate centering attachment device of test specimen, can be realized speed changer
It is connected by the quick and precisely centering of test specimen and main shaft, guarantees high concentricity requirement.
As shown in Figure 1, the centering attachment device is for realizing speed changer by the input shaft (or output shaft) of test specimen 10 and master
Axis 1 it is coaxially connected, comprising: bracket 7, terminal pad 8, transition disc 9 and pedestal 11.Wherein pedestal 11 is the centering attachment device
Mounting platform, spindle box 3 and bracket 7 are each attached on pedestal 11, and main shaft 1 is located in spindle box 3, and both ends pass through bearing support
On spindle box and spindle box 3 is stretched out, wherein one end is supported on spindle box 3 by single bearing 2, and the other end is by diagonally
Contact ball bearing 4 (or pairs of roller bearing) is supported on spindle box 3, wherein use pairs of 4 support end of angular contact ball bearing for
The revolution of support stiffness and main shaft 1 can be guaranteed using pairs of angular contact ball bearing 4 by the connecting pin of test specimen 10 with speed changer
Precision realizes high rigidity, the high-precision rotary of main shaft 1.The axial one end of pairs of angular contact ball bearing 4 passes through 3 inner periphery of spindle box
Step surface on face carries out axially position, and the other end carries out axially position by bearing (ball) cover 5.On main shaft 1 with speed changer quilt
10 connecting pin of test specimen is equipped with angular transducer 6 (grating).
Bracket 7 is L-type structure, and bottom surface is fixed on pedestal 8.Terminal pad 8 is fixedly mounted on the vertical plane of bracket 7,
And it is coaxial with main shaft 1, specifically: terminal pad 8 is that one end is provided with annular protrusion and the disc structure with central through hole, ring
Shape protrusion is located by connecting by seam allowance with bearing (ball) cover 5 after passing through the through-hole on 7 vertical plane of bracket, and the other end is perpendicular with bracket 7
It faces directly and is fixedly connected, the interface for being connected with speed changer by test specimen 10 is provided in terminal pad 8.
Transition disc 9 is fixed on speed changer by test specimen 10, and transition disc 9 is the disc structure with central through hole, transition disc 9
Centre bore and speed changer by the input shaft (or output shaft) of test specimen 10 coaxially, 9 one end of transition disc and speed changer are consolidated by test specimen 10
Fixed connection makes speed changer by the centre bore of input shaft (or output shaft) the output transition disc 9 of test specimen 10；The other end, which is provided with, to be used for
The interface connected with terminal pad 8.In this example, transition disc 9 and terminal pad 8 are coaxially connected by seam allowance；It is thus connected speed changer quilt
When test specimen 10 and main shaft 1, directly transition disc 9 is connected with terminal pad 8 by seam allowance, then again by speed changer by the defeated of test specimen 10
Entering axis (or output shaft) will be connect with main shaft 1 by spline housing, can realize speed changer by test specimen 10 input shaft (or output
Axis) it is connect with the quick centring of main shaft 1.
Terminal pad 8 realizes speed changer by main shaft in 10 input shaft of test specimen (or output shaft) and spindle box 3 quick and precisely
Centering connection ensure that high concentricity requirement, avoids bracket 7 and spindle box 3 and is directly connected to 7 concentricity of bracket and vertical
The shortcomings that spending high-precision requirement and causing processing difficulties, reduces processing cost.
The pairs of back-to-back centering mounting means of angular contact ball bearing 4 ensure that the installation rigidity of angular transducer, same to hour angle
Sensor 6 is spent to greatest extent close to speed changer by test specimen 10, reduces the loaded influence to measurement accuracy in the process of shafting.
In conclusion the above is merely preferred embodiments of the present invention, being not intended to limit the scope of the present invention.
