Abstract
The utility model belongs to a driving device of a steel converter, comprising a motor, a coupler, a primary and a secondary speed reducers. The driving device is characterized in that the mutual connection of the primary and the secondary speed reducers is changed from a flange form to a hollow shell shaft type, and a redundant structure with three supporting points is cancelled, so that the primary and the secondary speed reducers can do testing running-in alone. Thus, the utility model has easy fabrication, convenient installation and disassembly. The driving device is used for the suspended driving device of the steel converter and also other engaged flexible gearing.
Description
The utility model belongs to steel-making oxygen coverter drive unit.
In existing steel-making oxygen coverter integral formula drive unit, the slow-speed shaft of a step-down gear 3 is an outrigger shaft 9 that has pinion(gear) 8 and rolling bearing 7, the high speed shaft place of secondary speed-reducing machine 4 only processes portals, in the integral installation timing, outrigger shaft 9 is inserted in the above-mentioned hole, and step-down gear 3 and 4 is with the flange connection (see figure 1).This flange form drive unit has several shortcomings: 1. on an axle three fulcrums being arranged, is statically indeterminate structure, the processing and manufacturing difficulty; 2. secondary speed-reducing machine running-in and test run separately; 3. installing/dismounting bothers.
The purpose of this utility model is the shortcoming that overcomes said structure, and a kind of cover shaft type drive unit is provided, and it is easy to manufacture, easy for installation.
For achieving the above object, the technical solution of the utility model is: a step-down gear slow-speed shaft is made tubular shaft, and secondary speed-reducing machine high speed shaft is made cantilever shafts.During installation, on secondary speed-reducing machine high-speed side cantilever shafts, an end of cantilever axle head and tubular shaft links with a step-down gear low speed side hollow shaft sleeve, between cantilever shafts and tubular shaft key is housed or connects with other connecting modes, to transmit moment of torsion.One time the decelerator body body and function connecting rod connects with the secondary speed-reducing engine housing.The advantage of this structure: 1. secondary speed-reducing machine running-in has separately guaranteed the toothing precision; 2. easy installation and removal, servicing time is short; 3. cancelled three fulcrum statically indeterminate structures, easy to manufacture.
The utility model also can adopt sun and planet gear---spurn wheel except that the spurn wheel engagement,---spurn wheel, three-ring speed reducer---spurn wheel, worm gear---spurn wheel engagement that few tooth is poor.
This device not only is used for steel-making converter suspension type drive unit, also can be used in other engagement flexible gearing.
Further set forth cover shaft type structure below in conjunction with accompanying drawing.
Fig. 1 hangs the flange form drive unit
Fig. 2 hangs cover shaft type drive unit
Cover shaft type drive unit is made up of motor 1, shaft coupling 2, speed reduction unit 3 and secondary speed-reducing machine 4.Tubular shaft 10(Fig. 2) be contained in the low speed side of step-down gear 3, cantilever shafts 11 is contained in the high-speed side of secondary speed-reducing machine 4.During installation tubular shaft 10 is enclosed within on the cantilever shafts 11, cantilever axle head and tubular shaft link, and 10 of cantilever shafts 11 and tubular shafts connect with key or other bind modes, to transmit moment of torsion.The working process of cover shaft type drive unit is, motor 1 communications and liaison axial organ 2 and a step-down gear 3 link, and the rotation of motor makes tubular shaft 10 rotations by gear.Because key or other connections are rotated the cantilever shafts 11 of secondary speed-reducing machine 4, rotate thereby drive converter 6.
Claims (2)
1, drive unit is hung in a kind of converter, it is made up of motor (1), shaft coupling (2), a step-down gear (3) and secondary speed-reducing machine (4), it is characterized in that: the slow-speed shaft of a step-down gear is made tubular shaft (10), the high speed shaft of secondary speed-reducing machine is made cantilever shafts (11), during installation tubular shaft (10) is enclosed within on the secondary speed-reducing machine cantilever shafts (11), between tubular shaft (10) and cantilever shafts (11) end key is housed or connects with other modes, to transmit moment of torsion, an end of cantilever shafts and tubular shaft (10) links.
2, device according to claim 1 is characterized in that: the housing of a step-down gear (3) links with the housing of connecting rod and secondary speed-reducing machine (4).
