Description
The utility model relates to the main drive of rolling mill, tries out especially in the transmission of medium and small two rollers and three-high mill.
The sectional elevation pinion stand is compared with the horizontal profile pinion stand, can use rolling bearing, the transmission efficiency height, and meshing quality is good, and the bearing block that has thoroughly solved the horizontal profile pinion stand on the structure connects the problem of difficulty.The sectional elevation pinion stand structure of using is at present: two pairs of support bodys with dead eye that divide along the axis deep cutting are supporting two (three) gear shafts, and every pair of support all is to use Bolt Connection, connect with crossbeam between two pairs of support bodys, and upper and lower crossbeam is formed by four.These members with Bolt Connection after, formed the frames of gear shaft, frame is actually to be connected by 12 welding structural elements and forms.The between centers locating ring of gear shaft is located at the outside of each gear shaft dead eye.The bottom of frame is the box base, and it is the base for supporting of frame, is again that lubricating oil gathers case.Also covered a protective cover that had not only played protective action but also prevented lubricating oil splash in the outside of whole frame, there is following shortcoming in pinion stand in sum:
1, this pinion stand is many because of its structural member number, and is many in order to be combined into the used attachment bolt number of body, brings a lot of troubles so give to install to adjust;
Longer when 2, inspection and repair shop is taken a lot of work, every through after once overhauling, precision is affected;
3, each member of pinion stand all is a weldment, and the weld seam number is many, and the man-hour of using in the manufacturing is also many, and operation is loaded down with trivial details;
4, frame inside, protective cover version has outside increased difficulty for the installation of lubricating oil pipe, steel pipe is installed on the cover top, introduces in the protective cover with flexible pipe and receives on the oil site, when the flexible pipe exit seal on cover top was dealt with improperly, dust will fall in the body.
5, protective cover can not be done heavyly, therefore be welded into sheet metal, but yielding, so the root edge face sealing that combines with the box base is poor, be easy to oil impregnate herein.
The purpose of this utility model provides a kind of body intensity height, is convenient to design, and manufacturing process is simple, and is easy to maintenance, the pinion stand of good airproof performance.
The purpose of this utility model is achieved in that the sectional elevation pinion stand that the utility model provides is made up of master, passive herringbone bear spindle unit, box base, shell, be structure up and down, the cast casing on top is movably connected to form by two identical housings of structure, form two pairs of concentric holes up and down, bearing main, passive herringbone bear is placed in the hole, the installation side capping of the bearing outside, the bottom is both to play a supportive role, and plays the box base of lubricating oil collecting action again.
The sectional elevation pinion stand that the utility model provides, the shell lower end has stop flange, cooperates the movable connection in back with the seam of box base upper end, can resist the external force effect, avoids the string between shell and base moving.
The sectional elevation pinion stand that the utility model provides is characterized in that: the oil return ditch is arranged on the split surface of shell, and the oil return breach is arranged at the bottom.
The utility model sectional elevation pinion stand compared with prior art has the following advantages:
1, the cast casing of the utility model sectional elevation pinion stand has replaced the frame and the protective cover of the pinion stand of prior art, has both played the supporting role of gear shaft, plays protective action again.As long as two housings of shell are closed up, just become the powerful supporter of gear shaft, and had favorable protection and sealing, simple in structure, easy accessibility.Gear shaft upper body parts can have spare part, during maintenance, as long as unclamp the attachment bolt of upper case and box base, displace the main element of desire maintenance in the short period of time with spare part.The box base can be motionless, so need not to carry out machine row centering, operation in the accent;
2, the utility model sectional elevation pinion stand manufacturing process is easy, adds the precision that guarantees dead eye man-hour as long as make, and can not influence precision through later dismounting, has avoided too much influencing because of the Bolt Connection place in the prior art problem of precision;
3, shell of the present utility model and base rigidity are big, each faying face good airproof performance, and on two shell split surfaces, designed the oil return ditch, the flange of shell lower end has played oil-blocking action, so good seepage-proof property.
As long as 4, the utility model is opened the situation that handhole cover on bearing (ball) cover and the shell can be checked bearing and gear easily.
The utility model is described in more detail below in conjunction with embodiment:
Fig. 1 is the cutaway view of the utility model sectional elevation pinion stand along axis;
Fig. 2 is the side view of the utility model sectional elevation pinion stand.
Sectional elevation pinion stand shown in the figure is used for the transmission of two-roller mill, is assembled into initiatively herringbone bear shaft assembly by active herringbone gear shaft 1, bearing 4, tie-plate 9 and 6.Passive herringbone gear shaft 2, bearing 4, tie-plate 6 are assembled into passive herringbone bear shaft assembly.As shown in Figure 1, initiatively the herringbone bear shaft assembly deposits, passive herringbone bear shaft assembly is put, the shell 10 usefulness Bolt Connection that the two halves structure is identical form two pairs of concentric holes up and down, bearing 4 main, passive herringbone gear shaft is placed in the hole, the gear teeth are meshing with each other, the concentricity in coaxial two holes and with the centre-to-centre spacing of adjacent holes all by being guaranteed in the processing and manufacturing.Driving gear shaft 1 two ends are all overhanging, and through-hole side capping 5 is placed in the bearing outside, and 2 one ends of passive tooth wheel shaft are overhanging, and the bearing of an overhanging end is placed through-hole side capping 5, and the other end is placed blind hole side seal lid 3.Side seal lid 3,5 has played the effect of sealing, location.Designed oil return ditch 7 on the faying face of two half-shells, its effect is that savings is back in the body at the lubricating oil in the bearing outside, prevented that effectively the lubricating oil savings too much after, ooze out from the hole and the slit of axle of through-hole side capping.Above-mentioned member has been formed the superstructure of pinion stand.The lower end of shell 10 has stop flange 13, and it extend into the seam 12 of the box base 8 that is positioned at the gear shaft bottom, and the shell lower surface is combined with the upper surface of box base, connects with bolted.The whole machine body of formative gear seat.The shell of pinion stand not only plays a supportive role but also play protective action.The lubricating oil of the lubricated gear teeth and bearing is to flow in the cavity of box base 8 via lower housing portion breach 14, is back in the oil return pipe that is connected on the oil return opening 15 again, flows back to lubrication station.Design peep hole 11 on the shell, can observe the gear operation situation at any time.The inspection bearing can be opened side seal lid 3 and 5 and get final product.
One end of driving gear shaft links to each other with decelerator by end plate 9, and the end plate 6 of the other end and passive tooth wheel shaft links to each other with connecting axle, and the roll of connecting axle and milling train joins.Under the drive of motor, decelerator, driving gear shaft rotation because gear nibbles and drive that the passive tooth wheel shaft is relative to be rotated, thereby drives roll rotation, realizes rolling motion.
