Description
Technical field
The invention belongs to milling equipment technical field, more particularly, relate to a kind of rolling-mill housing and gearbox drive shaft centre line alignment device, the present invention also relates to the method applying described device centering simultaneously.
Background technology
The fixed milling train pattern of medium and small section has open type and closed type, and such rolling-mill housing is fixed with bolt and sole plate, after a usual centering, one-period can be used, when repairing in equipment next time, after gear-box again resets and installs, frame still needs again centering, fixing.The milling train of this pattern is when changing roll, frame is motionless, pair roller system changes, if frame centering is undesirable, breaker roll head and catcher (shaft coupling) cause larger unbalance loading, and local stress is comparatively large, roller head and catcher wearing and tearing aggravation, especially the roller head of wabbler roll and spline pattern causes and collapses tooth phenomenon, uses parts to scrap in advance.Therefore, the work of frame centering is very crucial.
The part that the output shaft of gear-box is exposed is usually all very short, brings inconvenience to milling train centering.The aligning method of current roller-type milling train has two kinds of modes usually:
One is by gear housing installation in position, is fixed on after on rail chair, open housing plate, two of gear output shaft end faces are all exposed, utilizes hanging wire method for centering, above axle, draw a horizontal linear, suspension wire hang on a horizontal, suspension wire near paraxial end face, by regulate, make two suspension wires respectively by the central point (datum mark) at axle two ends, the center line of suspension wire through output shaft is described.At milling train two window places, then hang a suspension wire respectively, measure suspension wire respectively whether equal with window two heel post distance, equal explanation suspension wire, just by window center line, illustrates milling train centering, otherwise, just need to regulate milling train position.Centering workload is large, and need the corresponding component on dismounting, erection unit, length consuming time, workload is large.
Another kind method is sight alignment method.Gear housing installation in position, fixing after, be directly taken at gear output shaft end face central point, other 2 are taken on the vertical center line of frame two side window, if these 3 in line, just think frame centering.The defect of this method is exactly treat as the center line of gear shaft with the central point of gear shaft end face, namely to put for line, so after such centering, the center line of gear shaft does not overlap with framework window center line, and two straight lines intersected, not complete centering often.
The reason of this phenomenon is caused to be: aligning method Shortcomings.Usual frame centering is after fastening completing installed by gear-box; again with gear-box shaft for benchmark; centering is carried out to breast roller longitudinal center line; and gear-box shaft is often all shorter; common aligning method is sight alignment formula, is more namely taken at the central point that gear-box goes out axial end, and other 2 are taken on the vertical center line of frame two side window; if in line, just think frame centering at these 3.The defect of this method is exactly treat as the center line of gear shaft with the central point of gear shaft end face, namely to put for line, so after such centering, the center line of gear shaft does not overlap with framework window center line, and two straight lines intersected, not complete centering often.
Summary of the invention
Technical problem to be solved by this invention is: for deficiency of the prior art, there is provided a kind of structure simple, rolling-mill housing centering can be realized quickly and easily, realize the adjustment of rolling-mill housing deviation distance, thus be convenient to rolling mill roll and gear-box setting angle is accurate, avoid because of setting angle mistake between milling train and gear-box, the rolling-mill housing causing milling train and gear-box to damage and gearbox drive shaft centre line alignment device.
Solve above-described technical problem, the technical scheme that the present invention takes is:
