Transmission mechanism is the important component part of double-roller cold pilger mill, and it all has a direct impact mill speed, stabilization of equipment performance, Product Precision and the output of double-roller cold pilger mill.Cold pilger mill adopts motor to drag belt transmission or reductor more in the prior art, and driving crank gear or bent axle realize that the reciprocating motion realization of frame is rolling again, and such transmission mechanism is subject to the impact of tube outer diameter, and is not suitable for large-scale cold rolling pipe machine; Or adopt hydraulic drive to come drive chassis to move back and forth to realize rolling, and the hydraulic cylinder of this mechanism is very large, and the pressure oil instantaneous delivery is very big, and the Design and manufacture of hydraulic cylinder and hydraulic system is had very large difficulty.
Summary of the invention
The transmission mechanism that the purpose of this invention is to provide a kind of double-roller cold pilger mill is applicable to large-scale double-roller cold pilger mill, can realize the needs that stable drive is reliable, shock loading is little.
Technical scheme of the present invention is a kind of transmission mechanism of double-roller cold pilger mill, which comprises at least motor, reductor and crank gear case, it is characterized in that: be provided with two pinions, two gear wheels, two one-throw crankshafts and two stand connecting rod in the crank gear case, wherein, a pinion and a gear wheel engagement, a gear wheel is fixedly installed on the one-throw crankshaft, a stand connecting rod is fixedly connected with the crank throw of an one-throw crankshaft and consists of one group of parts, and two groups of member connection structures are identical; Motor and reductor conducting, the output of reductor is connected with pinion by high speed shaft, and stand connecting rod is fixedly connected with frame.
Described two pinions are connected with the output of reductor by same high speed shaft, and namely high speed shaft makes two pinion interlocks.
Described two pinions pass through respectively the output conducting of a high speed shaft and a reductor, the quantity that is motor, reductor and high speed shaft all is two, a motor and a reductor conducting, the output of a reductor is connected with a pinion by a high speed shaft.
Described gear wheel can be eccentric gear.
All be provided with counterweight on described two one-throw crankshafts.
Characteristics of the present invention are to be provided with simultaneously gear wheel and one-throw crankshaft on the crank gear case, and increase counterweight at one-throw crankshaft, the gear wheel that is contained on the one-throw crankshaft also can be made eccentric gear, thereby avoided being subjected to tube outer diameter to affect in structural design, make the mistake of slider-crank mechanism apart from designing within zone of reasonableness, production tube also can pass through the crank gear case smoothly, thereby inertia force and the moment of inertia of mechanism kinematic have significantly been reduced, rigidity and the stability of equipment have been strengthened, improved the main frame speed of service, be of great importance for improving output.
