Embodiment approach 2

[0040] Embodiment 2, with image 3 The seven-frame plane secondary enveloping toroidal worm reducer PW type steel pipe tension reducer is shown as an example. The seven plane secondary enveloping toroidal worm reducers PW are exactly the same, and the installation directions are different. They are divided into upper and lower floors. The upper three planar double-enveloping toroidal worm reducers PW are vertically arranged, the output shaft CH is on the bottom, and the input shaft RU is on the top; the lower four planar double-enveloping toroidal worm reducers PW are also vertically arranged, but the output The shaft CH is at the top and the input shaft RU is at the bottom. Seven plane secondary enveloping toroidal worm reducers PW are installed on the welding bracket J in sequence. The schematic diagram of the transmission is attached Figure 4 shown.

[0041] Except that the bracket needs to be designed according to the installation size of the secondary enveloping toroi...

Embodiment approach 3

[0043] Embodiment 3, attached figure 2It is the transmission schematic diagram of a single three-ring reducer. The speed regulating motor D drives the gear C1, and then drives the gear C2 and the crankshaft of the three-ring reducer connected with it. The output gear G is connected with the output shaft CH to drive the roll stand. Others are the same as Embodiment 1.

Embodiment approach 4

[0044] Embodiment 4, attached Figure 4 It is a schematic diagram of the transmission of a single plane quadratic enveloping toroidal worm reducer. The speed regulating motor drives the bevel gear at z1, and then drives the bevel gear z2 and the worm WG connected with it, and the output shaft CH is connected with the worm wheel WL to drive the roll stand. Others are the same as Embodiment 1.

Abstract

The invention relates to a steel pipe tension-reducing mill, which belongs to the technical field of steel rolling devices, in particular to a steel pipe tension-reducing device. The steel pipe tension-reducing mill is characterized in that each output shaft and a driving system as well as a dynamic system belonging to the same are designed into mutually independent driving units and structural units, and the whole tension-reducing mill can be assembled like building blocks. The steel pipe tension-reducing device adopts three-ring speed reducers SA as the driving system from a speed regulating motor to the output shaft CH. An upper layer of the three-ring speed reducer and a lower layer of the three-ring speed reducer are arranged on a support frame J oppositely. The requirement on the speed changes of the output shaft of the tension-reducing mill is satisfied by adjusting the speed of the motor. The steel pipe tension-reducing mill cannot 'lose' speed before steel pipes get in, and has the advantages of firm mounting, easy adjustment, and convenient assembly and disassembly.

Description

technical field [0001] The invention relates to a building block type steel pipe tension reducing machine, which belongs to the technical field of steel rolling equipment, and in particular relates to a steel pipe tension reducing machine. Background technique [0002] There are two main types of steel pipe tension reducing equipment currently in use: [0003] I. Tension reducing machine with centralized differential speed [0004] The tension reducer with concentrated differential speed is generally driven by two speed-regulating motors, and the speed control and adjustment of each output shaft are realized through the differential mechanism installed on each shaft. The differential mechanism used is an NGW type differential mechanism or a bevel gear type differential mechanism. The main motor provides the speed n of a gear in the differential mechanism through a gear system 1 , the other motor provides the speed n of the other gear in the differential mechanism through ...
