As everyone knows, in non-ferrous metal rolling machinery hot continuous rolling unit field, generally all be to drive simultaneously two output shafts by a motor; And large-scale vertical miller reductor is high owing to complex structure, the accuracy of manufacture, for many years mainly relies on import.Along with over past ten years, the continuous enhancing of domestic mechanical process capacity, product quality and precision improve a lot; Along with the specification of tandem rolling unit is increasing, this increases the volume of power of motor and reductor with regard to inevitable requirement simultaneously.
Hot continuous rolling unit edger roll main transmission reductor requires stable drive, belongs to heavily loaded continuous operation, and has at work variable load, speed change, thump, so this reductor need have the performances such as high strength, high life and high reliability.
Therefore manufacture and design and a kind ofly novelly can satisfy instructions for use, and utilize compact space, reduce main transmission reductor cost, now become a kind of an urgent demand of gear-box manufacturing enterprise.
Summary of the invention
The purpose of this utility model is: a kind of hot continuous rolling unit edger roll main transmission reductor is provided, satisfy metallurgy industry edger roll main drive continuously, the working condition requirement of heavy duty, speed change, thump, compact conformation.
To achieve these goals, the utility model provides following technical solution: casing and case lid pass through double-screw bolt, nut, the alignment pin cabinet that is composed of a fixed connection, two groups of decelerators about installing in the cabinet, every group of decelerator comprises the input gear axle, the input coupling gear, double-row conical bearing, cylindrical roller bearing, taper roll bearing and eccentric bushing, one end of input gear axle is installed a double-row conical bearing, the other end is installed cylindrical roller bearing, the two ends of two input gear axles are installed in the dead eye of cabinet by eccentric bushing respectively, the axle head of each input gear axle connects with crown gear coupling by key respectively, mounted motor connects dish on the crown gear coupling, it is upper closing motor that motor connects dish, the two ends of two input coupling gears are supported by taper roll bearing and are fixedly mounted in the dead eye of cabinet by eccentric bushing, the input coupling gear is assembled together by fitting bolt closing by wheel rim and wheel hub interference, and the size of two input coupling gears equates, helical angle equates but rotation direction is opposite, output torque is transmitted in input coupling gear and the engagement of input gear axle, the input coupling gear of left decelerator meshes the input coupling gear of right decelerator simultaneously, realizes dual input, the kind of drive of dual output.
The utlity model has following advantage:
1, this reductor is comprised of dual input dual output single-stage driving, compact conformation, and cabinet is divided into case lid and casing two parts, and good manufacturability, convenient processing makes things convenient for gear lapping during assembling, effectively guarantee flank of tooth contact rate, especially assembles, dismantles very convenient.
2, the output gear wheel hub of this reductor and axle are monoblock type, and are hollow type, and spindle is can the retraction gear under the effect of hydraulic cylinder inner, and the extension elongation of spindle is shortened, and have reduced the height of milling train.
3, this reductor is adjusted the contact (area) pattern of gear by eccentric bushing, can effectively compensate the mismachining tolerance of cabinet by eccentric bushing, guarantees that gear contact pattern is good.
4, the cloth of motor puts together on motor and connects on the dish setting in the below of this reductor, motor arrangement below can increase the stationarity of transmission system, can also simplify the reductor superstructure, maintain easily.
5, output gear has been made assembled, and wheel rim and wheel hub combined interference are assembled together and are closed by the fitting bolt handle, greatly reduce the manufacturing cost of reductor.
6, edger roll main transmission reductor adopts the thin oil forced feed lubrication, the Lubricating-oil Station centralized oil supply, realize that by the oil-feed end cap bearing and point of mesh lubricate, wherein the meshing point place adopts engaging-in and nibbles out simultaneously fuel feeding of end, by casing and the simultaneously oil return of oil return end cap two places, final realization fuel feeding is abundant, and oil return is reliable.
