Component and the eccentric state of rotatable parts work so that there is serious damage and is delayed signal transmission in shaft coupling piece in collector ring,
The problem of causing radar cisco unity malfunction.
The present invention is to realize above-mentioned purpose by the following technical solutions：
The jacket-type oldham coupling is made of upper joint sleeve, lower joint sleeve, it is characterised in that：Upper joint sleeve by interior axle and
Upper key composition, lower joint sleeve are made of outer shaft and lower key；Interior axle is slided by upper key, lower key and outer shaft clearance fit；In interior axle
Symmetrical make in end has upper key, and interior axle lower end, which symmetrically makes, lower key, and upper key and lower key are in cruciform symmetry；It is in cruciform symmetry in outer shaft
Open and be formed with keyway；Upper joint sleeve passes through axis connection in bolt and collector ring by bolt and radar deep bid attaching, lower joint sleeve.
The upper joint sleeve and the axial fit clearance of lower joint sleeve are 2~3mm, ensure axial freedom.
The upper key and the displacement space of lower key along keyway radial direction are 5~6mm, can adjust the degree of eccentricity.
The upper key and lower key and the horizontal fit clearance of keyway are 0.5~1mm, ensure that interior axle is rotated and are moved with upper key
When dynamic, lower key is not interfered with keyway.
The beneficial effect of the present invention compared with prior art is:
The interior axle of the jacket-type oldham coupling realizes angular deviation and axis by upper key and lower key and outer shaft clearance fit
Adjusted to the free degree, it is ensured that radar slip ring interior axle concentricity, eliminates each fixed component installation and drive gap to confluence
The influence of ring interior axle concentricity, makes that collector ring operating is not eccentric, and collector ring is simple in structure using reliable and stable, easy to make.Through
Actual use proves, greatly reduces the serious damage of shaft coupling piece in collector ring, and the connection for effectively eliminating collector ring key adds up
Tolerance, is substantially reduced radar bearing error, and solving the prior art well does not have angular deviation and axial freedom adjustment
Function, it is difficult to correct radar fixed component and the eccentric state of rotatable parts work so that shaft coupling piece occurs tight in collector ring
The problem of weighing breakage and being delayed signal transmission, cause radar cisco unity malfunction.
