Abstract
The utility model discloses a three-roller sizing and reducing mill set with a novel structure, which solves the technical problems that output shafts of a speed reducer of the conventional three-roller sizing and reducing mill set are arranged on two sides of the speed reducer respectively and the overall device occupies a large area. The three-roller sizing and reducing mill set comprises a main motor (5), a speed reducer (3), a roller machine frame (2) and a machine frame replacing device (6), and is characterized in that an output shaft and an input shaft of the speed reducer (3) are arranged on the same side of the speed reducer (3); the main motor (5) is arranged on the main machine base (1) on the roller machine frame (2); an output shaft of the main motor (5) is connected with the input shaft of the speed reducer (3) through a shaft coupling (4); and the output shaft of the speed reducer (3) is connected with a roller machine. The three-roller sizing and reducing mill set has a simple structure, is convenient to control, and has a low cost.
Description
Technical field
The present invention relates to a kind of smelter seamless steel pipe production, the three-roll size reducing mill group in particularly a kind of seamless steel pipe equipment.
Background technology
At present, in smelter seamless steel pipe rolling production equipment, three-roll size reducing mill is one of seamless steel tube production capital equipment, both can be used for the tube reducing of deciding of final products, plays the tube reducing effect after also can being arranged in punch.Traditional three-roll size reducing mill, the output shaft branch of main motor and main gear reducer is located at the both sides of reductor, and floor space is big, in the little workshop of some areas,, equipment is installed had the difficult problem that to install because the place is limited, simultaneously, also limited to for the kind of drive of main motor.
Summary of the invention
The output shaft branch that the invention solves the reductor of existing three-roll size reducing mill is located at the both sides of reductor, makes that the entire equipment floor space is big, simultaneously the technical problem of also being limited to for the kind of drive of main motor.
The present invention overcomes the above problems by following scheme:
The three-roll size reducing mill group of new structure, comprise more changing device 6 of main motor 5, reductor 3, roll stand 2 and frame, the output shaft of described reductor 3 and power shaft all are arranged on the homonymy of reductor 3, described main motor 5 be arranged on main engine bed 1 on the roll stand 2 above, the output shaft of main motor 5 links together by the power shaft of shaft coupling 4 with reductor 3, and the output shaft and the roller mill of reductor 3 link together.
Total frame number of described three-roll size reducing mill group is the 1-10 frame.
The output kind of drive of the main motor 5 that is provided with respectively on the described 1-10 frame is for being the independent kind of drive, i.e. a main motor and the transmission of a reductor corresponding matching.
The output kind of drive of the described reductor 3 that is provided with on the described 1-10 frame is the grouping kind of drive, the power shaft that is reductor 3 is one, output shaft is two, a main motor 5 is connected with the power shaft of this reductor 3, and two output shafts of this reductor 3 link together with a roller mill separately.
The output kind of drive of the described reductor 3 that is provided with on the described 1-10 frame is the central driving mode, the power shaft that is reductor 3 is one, output shaft is ten, a main motor 5 is connected with the power shaft of this reductor 3, and each links together each output shaft of this reductor 3 with a roller mill.
The present invention has not only saved installing space, but also has made things convenient for the operation and maintenance of equipment, has satisfied the equipment installation and has been subjected to the user's of limited space requirement, and device structure is simple, and control is convenient, and is with low cost.
