Rotary transformer connects Worm gear mechanism by rotary transformer 8, MF type run-in index flexible clutch 9, optical axis 10, square tube
11 and worm gear composition.The horizontal flange end of double flanges 7 and the flange hole screw of 8 shell of rotary transformer (also referred to as stator) connect
It connects.The input shaft (also referred to as rotor) of rotary transformer 8 is held out against with screw B8 with 9 one end of MF type run-in index flexible clutch and is connect,
9 other end of MF type run-in index flexible clutch, which is held out against with one end of optical axis 10 with screw B8, to be connect.The other end of optical axis 10 and side
11 middle part of pipe holds out against connection with screw B9.There is the through-hole for passing through screw at 11 both ends of square tube, and square tube 11 and worm gear pass through bolt
It is fastenedly connected.When measuring different size of worm gear, the square tube of different length is replaced.
In order to adapt to the worm gear for measuring different height position in the future in the present invention, threaded rod 4 is designed as replaceable mode
, longer threaded rod is just changed for the worm gear of higher position.For this purpose, being provided with base flange 3, there is spiral shell in flanged pipe
Line mills out a pair of of plane, convenient wrench folder at the position that threaded rod 4 exposes base flange 3 to help threaded rod 4 to be smoothly screwed into
Application torque is held, and using the relative position of right-handed nut B4 fastening locking screw rasp bar 4 and base flange 3, then just by rotation
The height of anti-5 adjusting bracket of screw-thread sleeve, as shown in Figure 2.
The advantages of the present invention over the prior art are that:
(1) compared to paper disk method is inserted, measurement result is more acurrate, and measurement process is easier to operate.
(2) self-lock mechanism for utilizing worm and gear is directly connected to worm gear without fixed worm screw, easy to use and reliable.
(3) the transmission return difference of different height, worm gear within the scope of certain diameter can be measured.
(4) the horizontal positioned worm gear in end face can be measured by rotation legislation orchid, also can measure the snail that end face vertical is placed
Wheel.
(5) the MF run-in index flexible clutch that uses of the present invention is integrally formed metallic elastic shaft coupling, clockwise with
Turning anticlockwise characteristic is identical, has zero gyration aperture, good radial, angular, axial deviation compensation performance.So that this
Invention more convenient operation, measurement result are more reliable.
(6) rotary transformer of corresponding measurement accuracy needed for the accuracy selection according to needed for measurement return difference.Such as select Xi'an
The lighter weight of micro electronmechanical research institute, 64 pairs of poles of small volume 160XFS6421M rotary transformer, this is an assembly type
Rotary transformer install more convenient relative to separately-loaded rotary transformer.
(7) measurement that can be not only used for measurement turbine and worm transmission system transmission return difference, can also measure gear drive
Etc. shaftings transmission return difference measurement.
The application method of embodiment illustrated in fig. 2 device is specifically described below.
When using apparatus of the present invention, operating condition is placed according to worm gear first and selects rotary transformer bracket mounting means, when
Worm gear axis straight up, using mounting means shown in Fig. 4；When worm gear axis is horizontal positioned, using mounting means shown in Fig. 5.
Due to the latching characteristics for the worm and gear that the present invention utilizes, so without fixed worm screw when measurement return difference.
When installation, first square tube 11 is connected and fixed by the via hole at both ends with worm gear, then Worm Wheel System system is passed
Optical axis 10 is substantially moved to 11 interstitial hole of square tube by way of mobile base and rotation cantilever beam 6 by dynamic return difference measuring device
Top, need to press upper certain counterweight to pedestal later, prevent misoperation touching from toppling over.Then by rotating positive and negative screw-thread
The height of 5 adjusting bracket of sleeve, until being locked after optical axis 10 is inserted into the interstitial hole of square tube 11 with right-handed nut B4 and left-handed B5
The position of positive and negative screw-thread sleeve 5, and the optical axis 10 in square tube 11 is held out against by the threaded hole of square tube side with screw B9, guarantee
Square tube 11 with optical axis 10 fix always by relative position.In addition, can be mended according to the characteristic of MF type run-in index flexible clutch 9
A certain range of radial, angular, axial deviation is repaid, so when optical axis 10 and rotary transformer 8 join in MF type run-in index flexibility
It when axis device 9 is not coaxial in the range of limiting, does not still influence to use, so that operation of the present invention is more convenient.
After the measurement of Worm Wheel System drive system return difference is connected with worm gear, the rotation of manual toggle worm gear.Due to snail
The presence of the backlash of worm and gear, gear will drive square tube 11, optical axis 10, MF type run-in index shaft coupling 9 and rotary transformer 8
Input shaft (also referred to as rotor) rotation, rotary transformer 8 will under voltage signal curve record worm gear rotate angle.Lead to again
Analysis voltage signal curve is crossed, voltage signal is converted into return difference angle.The meaning of angle measurement is herein, directly measures
Be Partner disturbance caused by equipment angle of revolution, be reflected in antenna bearingt swing mechanism, be exactly that antenna bearingt is passively disturbed
Dynamic idle running L.The angle of revolution α measured with this, counter can also release power intake (worm shaft) needs in active drive
The angle value β to be dallied.
If disturbance idle running is L；The angle for needing worm gear to compensate is α；Reference circle of wormwheel radius is R；Worm screw lead is PZ；Snail
It is β that bar, which compensates idle angular,；Worm gear and the modulus of worm screw are m；Number of threads is Z1.Then: L=α R, L=Pz/ β, Pz=π
m·Z1；
So the angle value β that power intake (worm shaft) needs to dally in active drive, and then modified with this value
The angle compensation and lead of driving motor:
β=Pz/ (α R)=(π mZ1)/(α·R)
For the worm gear that measurement end face vertical is placed, bolt B 6 is tightened again i.e. after need to being only rotated by 90 ° when installing double flanges
It can.
This Worm Wheel System drive system return difference measuring device is also applied for the shaftings transmission system such as gear train assembly
It is driven return difference measurement, one of gear need to only be fixed, the input axis connection of another gear and rotary transformer 8, remaining
Specific embodiment is identical as Worm Wheel System system return difference measurement.
