Description
Technical field
The utility model relates to the mass balance device in the material processing plant, particularly a kind of bascule of cold-rolling pilger mill rolling-mill housing motion.
Background technology
At present, the reciprocating motion of cold-rolling pilger mill rolling-mill housing is to finish by the slider-crank mechanism of crankshaft rotating driven rotary arm mostly.Bent axle, turning arm, frame and roll produce periodically variable inertia force and the moment of inertia in high-speed motion, milling train is caused periodic impact, must take the antagonism measure to eliminate and impact, and then could improve mill speed, improve the output and the quality of finished product tubing.Normally on bent axle, add counterweight or increase new balanced controls and reduce impact.The technical measures that adopt have at present: one, add eccentric mass simply on bent axle, or use eccentric gear to substitute bent axle.This mode often counterbalance effect is undesirable.Two, add outside the eccentric mass on bent axle, the slide block that also adopts vertical links to drive on the another set of vertical direction comes balance.This mode need be built a dark melt pit, and the civil engineering difficulty is bigger; And because whole balance sysmte is positioned at undergroundly, maintenance cost is higher.Three, adopt one or more planetary mechanisms.This balance of mechanism is effective, but complex structure, installation difficulty is big.Four, adopt the balance weight horizontal arrangement, motor is by the opposite balance sysmte of Bevel Gear Transmission two cover direction runnings, and each balance sysmte has two or more trunnion shafves that dispose balance mass.This mechanism structure more complicated.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, a kind of bascule of cold-rolling pilger mill rolling-mill housing motion is provided, can active balance cold-rolling pilger mill frame and the inertia force and the moment of inertia of whole system, have counterbalance effect ideal, simple in structure, installation difficulty is little, maintenance cost is low characteristics.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of bascule of cold-rolling pilger mill rolling-mill housing motion, comprise drive motors, on the axle of drive motors first pinion is housed, first pinion and transition second pinion, second pinion and first gears engaged, first gear, first secter pat, flywheel are contained on the crank axle, first gear and second largest gears engaged, second largest gear, second secter pat, the 3rd secter pat are configured on the trunnion shaft, one end of crank axle and turning arm is connected, and the axle of the other end of turning arm and rolling-mill housing is connected.
Second secter pat on the trunnion shaft is disposed at crankcase inside.
The speed ratio of first gear and second largest gear is 1.
The center line of the center line of the center line of first pinion, second pinion, the center line of first gear and second largest gear is in a horizontal plane.
A kind of bascule operation principle of cold-rolling pilger mill rolling-mill housing motion is:
Driven by motor first pinion, by meshed transmission gear transition second pinion, and then first gear and second largest gear that transmission is contained in respectively on crank axle and the trunnion shaft rotate the reciprocating motion of driven rotary arm pulling frame with the cycle.
Of the present utility model being characterised in that:, disposed a flywheel that plays energy-storage function on the crank axle in order to guarantee the uniform and stable of speed; For simple formation transmission system under the enough strong situation of inertia balance, crank axle has disposed unique one first secter pat of a balanced action; Convenient for the mounting or dismounting of turning arm, second secter pat on the trunnion shaft is disposed at crankcase inside; In order to dispose the higher mill speed of acquisition under the rational situation, disposed and only disposed transition second pinion between first pinion of driven by motor and the first gear in appointed condition permission, gear ratio.
Because characteristic Design of the present utility model, solved that counterbalance effect is undesirable, installation difficulty is big, maintenance cost is higher, complex structure and other problems.
