Abstract
The utility model relates to a universal coupling of cathode rapping ceramic shafts for an electric dust collector, which mainly comprises a rotary ceramic shaft (3), a speed reducer and cathode rapping shafts which are totally connected by a bolt type universal coupling (2) at the connected points. The universal coupling of the utility model causes an ear fork of the rotary ceramic shaft and an ear fork of a connected shaft to be movably connected with a spherical coupling body through a pin shaft. After both ends of the rotary ceramic shaft use the coupling, rotary shafts on both ends of the rotary ceramic shaft are eccentric; the rotary ceramic shaft can not be damaged by twisting, and rotary operation of the whole rotary system is free from hindrance.
Description
Technical field
The utility model relates to the universal coupling that rotation porcelain axle two ends and rapping shaft are connected with the deceleration arbor in the cathode rapping mechanism of electric cleaner.
Background technology
During the electric cleaner operation, the inside rapping shaft of negative electrode and cathode rapping is to be with high-tension electricity, and what connect inner rapping shaft and external transmission device is insulation rotation porcelain axle.Rotation porcelain axle transmits moment of torsion, is again insulating component.When normal temperature was installed, inner rapping shaft, rotation porcelain axle, power transmission shaft adjustment were point-blank.Electric cleaner puts into operation, high-temperature gas passes through, equipment components produces and expands, inner swell increment is greater than the outside, cathode rapping axle inside and outside just not on same straight line, porcelain axle two ends and inside and transmission device are rigidly connected, and the easy rotation porcelain axle that electroceramics is made twists off, cause vibration body to damage, electric field send and does not power on.
Summary of the invention
The utility model provides a kind of turning cylinder decentraction that makes rotation porcelain axle two ends, and rotation porcelain axle can not turned round bad universal coupling.
The technical solution adopted in the utility model is: the cathode rapping rotation porcelain axle of this electric cleaner all connects with the bolt-type universal coupling with reductor and cathode rapping axle connecting place.
Described bolt-type universal coupling comprises that the ear fork on the rotation porcelain axle links to each other with the shaft coupling body through having strong market potential, and the ear fork of being furnished with on rapping shaft or the deceleration arbor links to each other with the shaft coupling body through the short pin of two tubuloses, and short pin is inserted in the groove of having strong market potential.Described shaft coupling body is spherical or oval.
Universal coupling of the present utility model is an ear fork of rotation porcelain axle and the ear fork of connecting shaft bearing pin and the flexible connection of spherical shaft coupling body mutually, after this shaft coupling is adopted at rotation porcelain axle two ends, member on the vibration body axis is because of the temperature rise difference, swell increment is different, make the turning cylinder decentraction at rotation porcelain axle two ends, can rotate between ear fork and the bearing pin, have dislocation angle, adjusting angle voluntarily, its error is within the specific limits the time, vibration body still can normal rotation, and rotation porcelain axle can not turned round bad, and whole rotation system rotating operation is not interrupted.
Description of drawings
The schematic diagram that Fig. 1 is connected with cathode rapping axle or deceleration arbor for the utility model rotation porcelain axle.
Fig. 2 is the profile of the utility model universal coupling.
Among Fig. 1,2, rapping shaft or deceleration arbor 1, universal coupling 2, rotation porcelain axle 3, alignment pin 4, the short pin 5 of tubulose, shaft coupling body 6, the ear fork 7 of rotation porcelain axle has strong market potential 8, rapping shaft or deceleration arbor ear fork 9, packing ring 10, steady pin plug 11.
The specific embodiment
In shown in Fig. 1,2, the two ends of rotation porcelain axle 3 link to each other with rapping shaft or deceleration arbor respectively through universal coupling 2.Connected mode 8 links to each other with shaft coupling body 6 through having strong market potential for the ear fork 7 of rotation porcelain axle, the ear be furnished with on rapping shaft or deceleration arbor fork 9 links to each other with shaft coupling body 6 through the short pin of two tubuloses 5, short pin 5 is inserted in 8 grooves of having strong market potential, be installed with a pivot pin in the short pin 5 of tubulose, it is fixing to lack pin 5 through packing ring 10, the steady pin plug 11 of the alignment pin 4 at top and bottom.During rotation by have strong market potential 8, active force between short pin 5 and shaft coupling body 6 threes drives.Rotate porcelain axle ear fork 7 and have strong market potential gapped between 8, also gapped between ear fork 9 on rapping shaft or the deceleration arbor and the short pin 5, shaft coupling 6 is regulated the position on both sides voluntarily, and making not, the rotating shaft on same center line rotates reposefully, guarantee that rotation porcelain axle can not twist off safe operation.
Claims (3)
1, a kind of universal coupling of cathode rapping porcelain axle of electric cleaner, comprise that mainly rotation porcelain axle two ends link to each other with the cathode rapping axle with reductor respectively, it is characterized in that: rotation porcelain axle (3) all connects with bolt-type universal coupling (2) with reductor and cathode rapping axle connecting place.
2, the universal coupling of the cathode rapping porcelain axle of a kind of electric cleaner according to claim 1, it is characterized in that: described bolt-type universal coupling (2) comprises that the ear fork (7) on the rotation porcelain axle (3) links to each other with shaft coupling body (6) through have strong market potential (8), the ear fork of being furnished with on rapping shaft or the deceleration arbor (1) (9) links to each other with shaft coupling body (6) through the short pins of two tubuloses (5), and short pin (5) is inserted in the groove of have strong market potential (8).
3, the universal coupling of the cathode rapping porcelain axle of a kind of electric cleaner according to claim 2 is characterized in that: described shaft coupling body (6) is for spherical or oval.
