Description

The two shift fork machine tool chief axis two of single splined shaft keeps off gearbox
Technical field
The utility model relates to the two shift fork machine tool chief axis two of a kind of single splined shaft and keeps off gearbox, belongs to field of machining.
Background technique
At present, lathe two gear shaft transmission all adopts gear transmission, cylinder or oil hydraulic cylinder is used to control selector fork during gearshift, handsetting gear to have slided gear shifting action at splined shaft, general splined shaft will install the gear of more than two, and need space to allow gear slide on splined shaft, splined shaft just becomes a major axis in Transmitted chains, spline axial length and middle without supporting, splined shaft can be made during transferring power to be easily out of shape, gear clearance becomes large, engaging position and state of rest error large, easily cause the spring bearing service life reduction at splined shaft two ends, axle cogs to wear and tear and strengthens, transmission gap between axle cogs increases change obviously with moment of torsion.
Model utility content
The purpose of this utility model is to provide the two shift fork machine tool chief axis two of a kind of single splined shaft to keep off gearbox, single shift fork is replaced with dynamic with two shift fork, simultaneously at a set of spring bearing of splined shaft medium design, reduce the support interval of splined shaft, there is the advantage strengthening transmission chain rigidity, reduce gear wear, improve gearbox working life.
For achieving the above object, the utility model is achieved through the following technical solutions:
The two shift fork machine tool chief axis two of single splined shaft that the utility model provides keeps off gearbox, comprise spindle motor, spindle motor to be fixedly connected splined shaft by splined shaft spring bearing, splined shaft top is provided with a gear input gear, one gear input gear connects a gear selector fork, splined shaft bottom is provided with two gear input gears, two gear input gears connect two gear selector forks, one gear selector fork and two gear selector forks are fixedly connected fork controls bar respectively, fork controls rod oil cylinder is fixedly connected fork controls bar, inner support bearing is provided with in the middle part of splined shaft, inner support bearing is fixedly connected on gear box casing by supporting frame, output gear wheels one end is fixed on gear box casing by gear train spring bearing, the output gear wheels the other end is fixedly connected on machine tool chief axis by spring bearing.
Supporting frame and gear box casing are provided with shift fork slide bushing.When fork controls bar slides in shift fork slide bushing, reduce friction, increase the sealing effect of gearbox simultaneously.
Output gear wheels have and can keep off input gear and two and keep off input gear meshed gears auxiliary section with one.
The utility model compared with prior art, has following beneficial effect:
The utility model changes project organization, support in the design of elongated splines axle, make the support of splined shaft sufficient, enhance Transmitted chains rigidity, when making stressed, gears meshing diminishes, and reduces gear wear, increase the life-span of spring bearing on gear and axle, reduce transmission internal cavity volume, bearing rib can be allowed more intensive, make gear-box more stable.
Accompanying drawing explanation
Fig. 1, the utility model one example structure schematic diagram.
In figure: 1, spindle motor, 2, fork controls rod oil cylinder, 3, shift fork slide bushing, 4, a gear selector fork, 5, one gear input gear, 6, bearing rib, 7, fork controls bar, 8, two gear input gears, 9, two gear selector forks, 10, machine tool chief axis, 11, gear box casing, 12, output gear wheels, 13, gear train spring bearing, 14, inner support bearing, 15, splined shaft, 16, splined shaft spring bearing.
Embodiment
Below in conjunction with embodiment, the utility model is described in further detail.
As shown in the figure, the two shift fork machine tool chief axis two of single splined shaft described in the utility model keeps off gearbox, comprise spindle motor 1, spindle motor 1 to be fixedly connected splined shaft 15 by splined shaft spring bearing 16, splined shaft 15 top is provided with a gear input gear 5, one gear input gear 5 connects a gear selector fork 4, splined shaft 15 bottom is provided with two gear input gears 8, two gear input gears 8 connect two gear selector forks 9, one gear selector fork 4 and two gear selector forks 9 are fixedly connected fork controls bar 7 respectively, fork controls rod oil cylinder 2 is fixedly connected fork controls bar 7, inner support bearing 14 is provided with in the middle part of splined shaft 15, inner support bearing 14 is fixedly connected on gear box casing 11 by bearing rib 6, output gear wheels 12 one end is fixed on gear box casing 11 by gear train spring bearing 13, output gear wheels 12 the other end is fixedly connected on machine tool chief axis 10 by spring bearing, supporting frame 6 and gear box casing 11 are provided with shift fork slide bushing 3, output gear wheels 12 have and can keep off input gear 5 and two and keep off input gear 8 meshed gears auxiliary section with one.
Gearbox is when shifting gears, and fork controls bar 7, under electromagnetism, hydraulic pressure or pneumatic action, drives gear selector fork 4 and two gear selector forks 9 simultaneously.Fork controls rod oil cylinder 2 reaches position, fork controls bar 7 drives a gear selector fork 4 and two gear selector forks 9 to move, one gear input gear 5 is engaged with cogging of output gear wheels 12, two gear input gears 8 are separated with the lower gear of output gear wheels 12 simultaneously, and output gear wheels 12 drive machine tool chief axis 10 to rotate; In like manner, when fork controls rod oil cylinder 2 is reduced to, two gear input gears 8 engages with the lower gear of output gear wheels 12, and while one keeps off input gear 5 and is separated with cogging of output gear wheels 12.Splined shaft 15 is fixed on bearing rib 6 by inner support bearing 14, enhances gear input gear 5 and two gear input gear 8 and degree of engagement for output gear wheels 12, gears meshing is diminished, enhances Transmitted chains rigidity.
In sum, the utility model changes project organization, support in the design of elongated splines axle, make the support of splined shaft sufficient, enhance Transmitted chains rigidity, when making stressed, gears meshing diminishes, increase the life-span of spring bearing on gear and axle, reduce transmission internal cavity volume, bearing rib can be allowed more intensive, make gear-box more stable.
