Abstract

The utility model relates to a main driving speed reducer of a three-roller continuous pipe rolling mill, which relates to a mechanical driving device. The utility model solves the problems that the speed reducer of a traditional continuous rolling mill can not satisfy the rolling requirement of a three-roller continuous rolling area, and the precision for rolling a thin-wall seamless pipe is not high. The continuous-rolling main driving of R1 to R2 frames is formed by three independent driving speed reducers in the utility model, a NO. I driving speed reducer and a NO. III driving speed reducer respectively adopt a vertically split inclined structure, and a NO. II driving speed reducer adopts a pedestal type parallel shaft structure; an included angle of 60 degrees is formed between the input shafts and the output shafts of the NO. I driving speed reducer and the NO. III driving speed reducer; a box body A and a box body C of the NO. I driving speed reducer are hung on a box body B, and the box body B is tightly laminated with an installing base surface; the NO. II driving speed reducer comprises an upper box body, a middle box body and a lower box body; and a box body D and a box body F of the NO. III driving speed reducer are hung on a box body E, and the box body E is connected with a pedestal and installed on the base surface.

Description

A kind of main transmission speed reducer of three-roll continuous rolling pipe machine
Technical field
The utility model relates to mechanical driving device, the main transmission reductor in particularly a kind of tube mill three-roll continuous rolling district.
Background technology
Along with the increase of world oil demand, exploit in a large number in the oil field, and the situation that supply falls short of demand appears in the high accuracy thin-wall seamless steel pipe.Two roller MPM tandem mill reductors of prior art, every reductor transmission by a platform independent, reductor is to go out structure into two, the MPM tandem mill can the rolling thin-wall seamless pipe, but the pipe precision is not high.The ASR three-high mill is driven by the reductor of three platform independent altogether, is parallel axes base type structure, though ASR three-high mill reductor is simple in structure, it is not a continuous rolling, can only rolling thick walled steel tube.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of main transmission speed reducer of three-roll continuous rolling pipe machine is provided, and solves the rolling requirement that traditional tandem mill reductor can not satisfy the three-roll continuous rolling district, the not high problem of rolling thin-wall seamless pipe precision.
The utility model is achieved through the following technical solutions:
A kind of main transmission speed reducer of three-roll continuous rolling pipe machine, it is characterized in that: formed the tandem rolling main transmission of R1 to the R6 frame by three kinds of separate transmission reductors, I transmission speed reducer and III transmission speed reducer adopt deep cutting to divide the italic structure, and the II transmission speed reducer adopts base type parallel axes structure; The power shaft of described I transmission speed reducer and III transmission speed reducer becomes 60 ° of angles with output shaft; The I transmission speed reducer is made up of A casing, B casing, C casing, and A casing and C casing hang on the B casing, and B casing and installation base surface fit tightly; Described II transmission speed reducer is made up of upper box, middle casing, lower box; Described III transmission speed reducer is made up of D casing, E casing, F casing and base, and D casing and F casing hang on the E casing, and the E casing connects with base and is installed on the basal plane.
The utility model compared with prior art, because every frame of three-roller continuous rolling mill is finished by three kinds of identical separate transmission of speed ratio, the space structure of three kinds of separate transmission is also inequality, not only satisfy the requirement of three-roll continuous rolling pipe rolling line, and novel structure, bearing capacity height, maintenance and maintenance facility.
Description of drawings
Fig. 1 is a kind of structural representation of main transmission speed reducer of three-roll continuous rolling pipe machine;
Fig. 2 is that the C of Fig. 1 is to view;
Fig. 3 is that the B of Fig. 1 is to view;
Fig. 4 is that the A of Fig. 1 is to view.
The utility model is further described by preferred embodiment below in conjunction with accompanying drawing.
The specific embodiment
Shown in Fig. 1,2,3,4 (is that example is carried out the structure explanation with R1, the main transmission of R2 frame tandem rolling), a kind of main transmission speed reducer of three-roll continuous rolling pipe machine, formed the tandem rolling main transmission of R1 by three kinds of separate transmission reductors to the R6 frame, I transmission speed reducer 1 and III transmission speed reducer 3 adopt deep cutting to divide the italic structure, and II transmission speed reducer 2 adopts base type parallel axes version; The power shaft of I transmission speed reducer 1 and III transmission speed reducer 3 becomes 60 ° of angles with output shaft; I transmission speed reducer 1 is made up of A casing 1.1, B casing 1.2, C casing 1.3, and A casing 1.1 and C casing 1.3 hang on the B casing 1.2, and B casing 1.2 fits tightly with installation base surface; II transmission speed reducer 2 is made up of upper box 2.1, middle casing 2.2, lower box 2.3; III transmission speed reducer 3 is made up of D casing 3.1, E casing 3.2, F casing 3.3 and base 3.4, and D casing 3.1 and F casing 3.3 hang on the E casing 3.2, and E casing 3.2 connects with base 3.4 and is installed on the basal plane.
