Description
Technical field
The utility model relates to rolling machinery teaching mode, particularly a kind of down-pressing system of rolling mill gear train teaching model.
Background technology:
The principle of work of existing down-pressing system of rolling mill is that two motors slow down respectively by gear pair, worm gear and worm gear pair and drive two housing screws to rotate, and coordinate formation to be threaded with the screw box be fixed in frame in the middle part of housing screw, afterbody is connected with worm gear by spline, thus realizes roll gap regulation.Because its press down system is positioned at above frame, and gear train belongs to closed-type cylindrical gearing, is difficult at the scene understand its inner structure and principle of work, and screw box is fixed in frame and is difficult to especially observe, and its component weight and volume are all very large.
Teaching mode about rolling machinery on current classroom is little, cause teacher can not show classmates by vivid for the principle of work of down-pressing system of rolling mill, class teaching content is abstract, form of teaching is single, lack enjoyment, and theory and practice can not organically combine.
Utility model content
The utility model provides a kind of down-pressing system of rolling mill gear train teaching model, can show the principle of work of down-pressing system of rolling mill vividly.
A kind of down-pressing system of rolling mill gear train teaching model that the utility model provides comprises: a pair gear wheel, four shaft couplings, a pair worm gear, two housing screws, a coupling shaft, four bearings, a pair worm screw, a pair pinion wheel, a motor, a motor frame, two frames, two rolls and four bearing seats, described motor is fixed on motor frame, be connected with pinion wheel, pinion wheel and gear wheel meshing, pinion wheel and gear wheel carry out primary speed-down, worm screw is driven to rotate by shaft coupling, worm screw connects worm gear by coupling shaft, carry out double reduction, worm gear is hollow-core construction and is processed with internal thread, play the effect of screw box, screw-driven is formed with housing screw, on housing screw fixed bearing block, housing screw is at the slide on rails of frame, drive roll rectilinear motion, realize roll gap regulation, described gear wheel, shaft coupling, worm gear, coupling shaft, the rotation axis of worm screw and pinion wheel is all equipped with bearing.
Described motor adopts GPG-05SC type DC speed-reducing, and power is 10W, and rotating speed is 600rpm, bi-directional rotary.
The beneficial effects of the utility model are embodied in:
1. by mechanically operated typical part---worm gear and worm screw, gear, screw and nut integrate very dexterously on a model;
2. in the design of screw box, worm gear both can be used as the driving parts of double reduction, can be used as again the screw box realizing pressure adjustment, the two was united two into one, and served a dual-purpose effect, saved material, reduce and taken up space;
3. this model can be used for the teaching of the multi-door courses such as rolling machinery, Machine Design, mechanical principle, metallurgical equipment robotization, machinery maintenance, is with a wide range of applications;
4. adopt light material, there is little, the lightweight feature of volume, be convenient to deposit and carry;
5. frame employing organic glass material, makes frame have enough strength and stiffness and anti-wear performance is good, can extend the serviceable life of teaching aid, and can also observe its inner structure knot and transmission principle intuitively;
6. all part drawings all adopt soildworks draw and be assembled into wiring layout.
