Abstract
Disclosed is a gear assembly of a continuous tube rolling mill for hot-rolled seamless steel tubes. The gear assembly is characterized by comprising a combined box base with the top face in a 30-degree slope, a combined box arranged on the top face of the combined box base, and at least three reducers mounted in the combined box side by side, working independently and respectively provided with corresponding driving motors; an input shaft of each reducer is arranged horizontally, and each output shaft and the corresponding input shaft are arranged at a 60-degree included angle.
Description
Technical field
The utility model relates to a kind of many transmissions angle class combination box gear drive, especially relates to the gear drive of the mandrel mill of hot rolled seamless steel tube.
Background technology
Seamless steel pipe is that one has hollow section, periphery does not have jointed circle, square, rectangle steel.Seamless steel pipe is to make hollow billet with steel ingot or the solid pipe hole that wears long, and then makes through hot rolling, cold rolling or cold group.Seamless steel pipe has hollow section, a large amount of pipelines as carrying fluid, and compared with the solid steel such as steel pipe and round steel, in the time that bending resistance torsional strength is identical, weight is lighter, is a kind of Economic Section steel.Be widely used in the every field such as oil, chemical industry, boiler, power station, boats and ships, machine-building, automobile, Aeronautics and Astronautics, the energy, geology, building and military project.The mandrel mill of hot rolled seamless steel tube is the critical piece of making seamless steel pipe.The manufacturing process of round seamless steel pipe is: circular blank, and---blank being worn into hollow heavy wall hollow billet on punch---will put on plug in hollow billet, on mandrel rolling mill, be mutually the duo mill tandem rolling of 90 ° of configurations---the rod of loosing core after rolling by 7～9 roll axis, through carrying out stretch reducing after heating again, can roll into required steel pipe.
Summary of the invention
The utility model object is to provide the gear drive that a kind of structure is more reasonable, can realize the mandrel mill of the hot rolled seamless steel tube of the continuous roll forming of hollow billet---many transmissions angle class combination box gear drive.
The purpose of this utility model can realize by following technique measures:
The gear drive of the mandrel mill of hot rolled seamless steel tube of the present utility model comprises that end face is the combination box base on 30 degree slopes, be arranged on the combination box on combination box base top surface, be arranged on side by side at least three reductors that work alone separately, are furnished with separately corresponding drive motors in described combination box; The power shaft horizontal positioned (being convenient to be connected with drive motors) of described reductor, output shaft becomes 60 degree angle settings with power shaft.
Reductor power shaft described in the utility model and secondary gear axle clamp angle are 60 degree, by bevel gear pair transferring power; The input of described reductor power shaft combines with drive motors, the output of power shaft is sent to power on secondary gear axle by bevel gear pair, secondary gear axle is meshed with secondary tooth bull wheel, power is sent on tertiary gear axle, tertiary gear axle is meshed with three grades of tooth bull wheels and drives output shaft rotation, thereby realizes the roll work being connected with output shaft.
The beneficial effects of the utility model are as follows:
The utility model advantage is by described gear drive, has realized the continuous roll forming of hollow billet, has improved operating efficiency.By tertiary gear transmission, realize high pulling torque output, meet the needs of operating mode.And working alone of every drive motors, has been convenient to realize the sequential control of roll.
Brief description of the drawings
Fig. 1 is the cutaway view of the utility model gear drive.
Fig. 2 is the front view of the utility model gear drive.
Fig. 3 is the top view of the utility model gear drive.
Detailed description of the invention
The utility model is further described below with reference to embodiment (accompanying drawing):
As shown in Figure 1, the gear drive of the mandrel mill of hot rolled seamless steel tube of the present utility model comprises that end face is the combination box base 5 on 30 degree slopes, be arranged on the combination box 10 on combination box base top surface, be arranged on side by side at least three reductors that work alone separately, are furnished with separately corresponding drive motors in described combination box; Power shaft 1 horizontal positioned (being convenient to be connected with drive motors) of described reductor, output shaft 8 becomes 60 degree angle settings with power shaft.
Reductor power shaft 1 described in the utility model is 60 degree with secondary gear axle 4 angles, by bevel gear pair transferring power.More specifically: the input of described reductor power shaft 1 combines with drive motors, on power shaft 1, be provided with input bevel gear 2, be meshed with output bevel gear 3 by input bevel gear 2, power is sent on secondary gear axle 4, secondary gear axle 4 is meshed with secondary gear wheel 6, power is sent to again on tertiary gear axle 7, tertiary gear axle 7 is meshed with three grades of gear wheels 9, power is ultimately delivered on output shaft 8, output shaft 8 drives roll 11 to rotate, thereby by Multi-stage transmission, drive the roll work of high pulling torque.
The utility model operation principle is summarized as follows:
As shown in Figures 2 and 3, when use, first the combination box base 5 of described gear drive is arranged on the Horizon of production line, and regulates, make it become 30 degree angles with ground level.Again combination box (gear housing) 10 is installed on combination box base 5, makes its output shaft and horizontal position be set to 60 degree angles.
Drive power shaft 1 to rotate by drive motors, power shaft 1 is engaged power is sent on secondary gear axle 4 by bevel gear pair, secondary gear axle 4 is sent to power on tertiary gear axle 7 by the secondary engagement of secondary gear, tertiary gear axle 7 is sent to power on output shaft 8 by the secondary engagement of tertiary gear, output shaft 8 drives roll 11 to rotate, and has realized the work of roll.
Because described gear drive is to be combined by the reductor of 3 platform independent, and the motor drive that the power shaft of every reductor is matched by it, thereby when having realized single breaker roll work or multipair roll, work, can realize different performance characteristics according to demand.At present most what adopt is that multipair roll is worked simultaneously, thereby the processing of continuous high-efficient has improved the manufacture output of seamless steel pipe.
