Specific embodiment
With reference to the accompanying drawings and examples, specific embodiments of the present invention will be described in further detail.Implement below
Example is not intended to limit the scope of the invention for illustrating the present invention.
In conjunction with shown in Fig. 1 to Fig. 6, schematically show that ram drive gap of the invention eliminates component, including pedestal 1
And the ram 2 being rotatablely connected with it, the main shaft of lathe are mounted on ram 2,2 opposite base 1 of ram, which verts, can be adjusted master
The angle of axis and workpiece enables lathe to process in multiple angles to workpiece.Such as Fig. 3 and Fig. 4, pedestal 1 is equipped with and cunning
The driven gear 3 of the coaxial setting of pillow 2, ram 2 are equipped with the first driving gear 4 and the second active that axis coincides
Gear 5 is fixedly provided with installation axle 41 on first driving gear 4 such as Fig. 1, and the second driving gear 5 offers mounting hole 51, peace
Dress axis 41 wears and is connected to mounting hole 51, and the end face of the first driving gear 4 and the end face of the second driving gear 5 abut against,
This is combined into one the first driving gear 4 and the second driving gear 5.First driving gear 4 and the second driving gear 5 engage
In driven gear 3, it is to be understood that the thickness of the thickness of the first driving gear 4 and the second driving gear 5 is respectively less than driven tooth
Wheel 3 thickness (spacing that the thickness of gear refers to two end faces of gear herein), with this reduce the component volume and
The gear teeth of weight, the gear teeth of the first driving gear 4 and the second driving gear 5 are connected to the opposite flanks of driven gear 3 respectively, into
And inter-lobe clearance is eliminated, transmission accuracy is not only improved, but also ram 2 can be prevented opposite when lathe processes workpiece
Pedestal 1 generates exception and verts, and further promotes machining accuracy.
Hollow shaft 52 is additionally provided on second driving gear 5, installation axle 41 is arranged in the center of mounting hole 51 and hollow shaft 52
Hole, hollow shaft 52 can promote the being completely embedded property of the second driving gear 5 and the first driving gear 4, further prevent the second active
The axis of the axis of gear 5 and the first driving gear 4 generates deflection, and certainly, the second driving gear 5 and hollow shaft 52 can be one
Body structure, mounting hole 51 and the centre bore of hollow shaft 52 are the same hole at this time.Specifically, the one of the first driving gear 4
End is equipped with transmission shaft 42, and the other end is equipped with above-mentioned installation axle 41, and transmission shaft 42 is rotationally connected with cunning by the first thrust bearing 21
Pillow 2, hollow shaft 52 are rotationally connected with ram 2, the first thrust bearing 21 and the second thrust bearing 22 by the second thrust bearing 22
Thrust it is contrary, therefore can also to provide thrust power first main to force for the first thrust bearing 21 and the second thrust bearing 22
Moving gear 4 and the second driving gear 5 tightly fit.
In order to which the deflection angle between the first driving gear 4 and the second driving gear 5 is adjusted and by two actives
Gear is mutually locked, which further includes tensioner washer 6 and end cap 7, and in conjunction with shown in Fig. 1 and Fig. 6, tensioner washer 6 further includes phase
The contact surface of the inner ring 61 of abutting and outer ring 62, inner ring 61 and outer ring 62 is the conical surface, when external force forces inner ring 61 and outer ring 62 to exist
It is moved toward one another in axial direction, the internal diameter of inner ring 61 can reduce, and the outer diameter of outer ring 62 can expand, and the both ends of tensioner washer 6 connect respectively
It is connected to mounting hole 51 and installation axle 41.End cap 7 is bolted to the end of installation axle 41, and adjusting bolt can be adjusted end cap
7 are connected to one end (in the present embodiment, end cap 7 of tensioner washer 6 with the spacing of the end of installation axle 41, the end face of end cap 7
End face is connected to the end face of outer ring 62, and the end face of inner ring 61 is connected to the end face of the shaft shoulder in installation axle 41), therefore, adjusting
When bolt, the spacing of the end of end cap 7 and installation axle 41 reduces, so that the end face of end cap 7 applies the outer ring 62 of tensioner washer 6
Pressure forces 61 banding installation axle 41 of inner ring, and outer ring 62 expands and pushes against mounting hole 51 (or centre bore of hollow shaft 52)
First driving gear 4 is connected by hole wall with this with the second driving gear 5.It is, of course, understood that fastening above-mentioned end
Before lid 7, the deflection angle of the first driving gear 4 and the second driving gear 5 should be manually adjusted, so that the first driving gear 4
The gear teeth of the gear teeth and the second driving gear 5 push against the opposite flanks of driven gear 3 respectively.
The component is additionally provided with driving mechanism 8, and driving mechanism 8 includes driving pulley 81, driven pulley 82, is wound in main belt
The transmission belt 83 and driving device 84 set on ram 2 of wheel 81 and driven pulley 82, driving device 84 are motor, transmission belt
83 preferably synchronous belt, driving pulleys 81 are connected to driving device 84, and driven pulley 82 is connected to the first driving gear 4, synchronous
Tape handler stable drive and peace and quiet in the case where ensuring transmission accuracy.In the present embodiment, the fan-shaped knot of driven gear 3
The head end of structure, ram 2 is rotationally connected with pedestal 1 by shaft, and the first driving gear 4 and the second driving gear 5 are respectively positioned on ram 2
Tail end.Certainly, in certain optional embodiments, driving device 84 can also be directly connected in the biography of the first driving gear 4
Moving axis 42, so that driving device 84 directly drives the rotation of the first driving gear 4.
In conclusion ram drive gap of the invention eliminates component, ram 2 is equipped with the first driving gear 4 and the
Two driving gears 5, the mounting hole 51 on the second driving gear 5 are socketed in the installation axle 41 on the first driving gear 4, and two masters
The end face of moving gear abuts against, and the gear teeth of the gear teeth of the first driving gear 4 and the second driving gear 5 are connected to respectively on pedestal 1
Driven gear 3 opposite flanks, and then eliminate inter-lobe clearance, realize high-precision be driven, avoid ram 2 from adding in machine tool chief axis
Working hour opposite base 1 generates abnormal the case where verting, and the first driving gear 4 and the second driving gear 5 are combined into one, and reduce this
The weight and volume of component, so that the rotary inertia of ram 2 is smaller.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and replacement can also be made, these are improved and replacement
Also it should be regarded as protection scope of the present invention.
