Abstract
A vertical mill consists of a machine frame, two rolls, a roll driving system, a synchronous shaft and a rolled plate width controlling mechanism, wherein, the roll driving system comprises two roll driving mechanisms each formed by a hydraulic motor and a reducer, which are respectively arranged on the left and right sides of the machine frame; the spindle of the hydraulic motor is directly connected with the transmission input end of the reducer; the output shaft of the reducer is in transmission connection with the roll; the reducer is directly driven by the hydraulic motor so as to drive the roll to rotate; the synchronous shaft is arranged between two reducers and connected with two reducers through bevel gears in transmission type, so as to make two rolls in the same rotational speed. The utility model adopts the hydraulic motor with low rotational speed and high torque for driving, greatly simplifies the transmission system of the vertical mill, can realize the integrated assembly of the vertical mill so as to make the integral roll changing mode capable of being used in fast roll changing, can realize off-line maintenance and also provides convenience for on-line maintenance.
Description
Technical field
The utility model relates to the vertical miller that a kind of metallurgy strip material production line is used.
Background technology
The vertical miller that metallurgy strip material production line is used generally comprises members such as organic frame, roll, roll drive system, synchronizing shaft and width of plate slab controlling organization, but the assembling of existing strip material production line vertical miller is more complicated all, adopt motor-driven mostly, because the overload capacity of motor is less, environment for use requires high, for solving the environment for use and the low problem of overload capacity of motor, mostly adopt and increase motor and motor is arranged in position away from roll, cause investment big, the roll change difficulty, roll changing time long (generally wanting 7 hours).
Summary of the invention
The purpose of this utility model is the assembling integration of a kind of energy of proposition realization system, can adopt the vertical miller of the mode of whole fast roll changing.
The vertical miller that the utility model is designed, its structure is by frame, roll, the roll drive system, synchronizing shaft and roll plate width controlling organization and constitute, it is characterized in that said roll drive system comprises two roll driving mechanisms that are made of hydraulic motor and reductor, be installed in the left side of frame respectively, right both sides, the main shaft of hydraulic motor is directly connected to the transmission input of reductor, the output shaft and the roll of reductor are in transmission connection, directly drive reductor and then drive roll rotation by hydraulic motor, described synchronizing shaft is installed between two reductors, be in transmission connection by bevel gear and two reductors, so that the rotating speed unanimity of two rolls.
When described vertical miller is the cantilevered vertical miller, the described plate width controlling organization that rolls comprises two side pressure oil cylinders and two balancing cylinders, two side pressure oil cylinders are installed in the both sides of frame respectively, and the piston of two side pressure oil cylinders is connected with the outside of two reductors respectively; Two balancing cylinders also are installed on the frame, and the piston of two balancing cylinders is connected with the inboard of two reductors respectively.
When described vertical miller was the frame-type vertical miller, the described plate width controlling organization that rolls was made of two side pressure oil cylinders, and two side pressure oil cylinders are installed in the both sides of frame respectively, and the piston of two side pressure oil cylinders is connected with the outside of two reductors respectively.
Vertical miller of the present utility model adopts the fluid motor-driven of low rotation speed large torque, makes the gearratio of its transmission system become very little, and it is simple that the structure of reductor also becomes; Because hydraulic motor has high temperature resistant and resistance to water, makes the transmission system of vertical miller become simply, can realize vertical miller integration assembling, thereby can adopt the mode of whole roll change to carry out fast roll changing, make roll changing time shorten greatly; Can realize the off-line maintenance, also make things convenient for on-line maintenance.
Vertical miller small investment of the present utility model has only 1/3 investment of conventional vertical miller, has good economic benefit.
