Description
Technical field
The invention belongs to the mass balance system in the material processing plant, particularly a kind of horizontal mass balance system with single-arm crankshaft and double-sector block.
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 objective of the invention is to overcome the shortcoming of above-mentioned prior art, a kind of horizontal mass balance system with single-arm crankshaft and double-sector block 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 used in the present invention is:
Horizontal mass balance system with single-arm crankshaft and double-sector block, comprise drive motors 13, on the axle of drive motors 13 pinion 12 is housed, pinion 12 and 11 engagements of transition pinion, pinion 11 and gear wheel 9 engagements, gear wheel 9, secter pat 2, flywheel 3 are contained on the crank axle 4, gear wheel 9 and gear wheel 10 engagements, gear wheel 10, secter pat 6, secter pat 7 are configured on the trunnion shaft 8, and an end of crank axle 4 and turning arm 5 is connected, and the axle of the other end of turning arm 5 and rolling-mill housing 1 is connected.
Secter pat 6 on the trunnion shaft 8 is disposed at crankcase 14 inside.
The speed ratio of gear wheel 9 and gear wheel 10 is 1.
The center line of the center line of the center line of the center line of pinion 12, pinion 11, gear wheel 9 and gear wheel 10 is in a horizontal plane.
The horizontal mass balance system with single-arm crankshaft and double-sector block operation principle is:
The invention is characterized in:, disposed a flywheel 3 that plays energy-storage function on the crank axle 4 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 4 has disposed unique secter pat 2 of a balanced action; Convenient for the mounting or dismounting of turning arm 5, the secter pat 6 on the trunnion shaft 8 is disposed at crankcase 14 inside; For allow at appointed condition, gear ratio disposes the higher mill speed of acquisitions under the rational situation, disposes and only disposed a transition pinion 11 between pinion 12 that is driven by motor 13 and the gear wheel 9.
Because characteristic Design of the present invention, solved that counterbalance effect is undesirable, installation difficulty is big, maintenance cost is higher, complex structure and other problems.
