Summary of the invention
Technical problem to be solved by this invention is to provide a kind of driving box device of gear shaving machine, and it can be fastened at same axle and realize rotatablely moving and axial back and forth movement.
For solving the problems of the technologies described above, the technical solution of the driving box device of gear shaving machine of the present invention is:
Comprise drive motors, the output shaft of drive motors connects the driving worm screw, drives worm screw and is meshed with the driving worm gear; Driving worm gear is fixedly installed on the driving splined shaft; Drive on splined shaft and be arranged with hollow spline leading screw, be fixedly installed the lifting worm gear on hollow spline leading screw, promote worm gear and be meshed with the lifting worm screw; Promote the output shaft that worm screw connects lifting motor; Be provided with the gap between described hollow spline leading screw and driving splined shaft, make the spinning movement of driving splined shaft and the spinning movement mutually noninterfere of hollow spline leading screw; Be movably set with feed screw nut on hollow spline leading screw, feed screw nut is fixedly connected with slide; An end that drives splined shaft is provided with driving bevel gear; Drive motors drives the splined shaft rotation by driving worm screw and driving worm gear drives, can drive the driving bevel gear rotation; Driving bevel gear is flexibly connected with driving splined shaft by spline, can drive driving bevel gear when driving the splined shaft rotation and rotate together, and driving bevel gear drives splined shaft motionless when moving up and down along axis direction; Lifting motor makes feed screw nut move up and down along hollow spline leading screw by promoting worm screw and promoting the hollow spline leading screw rotation of worm gear drives, and feed screw nut can drive driving bevel gear by slide and move up and down.
Described hollow spline leading screw and the coaxial setting of driving splined shaft.
The lower end of described driving splined shaft is provided with spline mechanism; Be provided with on driving bevel gear and the endoporus that drives the splined shaft end surface shape and match.
The technique effect that the present invention can reach is:
The present invention adopts two cover Worm Wheel Systems and a cover ball-screw-transmission structure, and this three covers fine structure is carried out perfect adaptation, coexists thereby realized rotatablely moving fastening at same axle with axial back and forth movement, and the overall structure operation is highly stable, safety, reliable, noise is extremely low.

The specific embodiment
As shown in Figure 1, the driving box device of gear shaving machine of the present invention comprises drive motors 4, and the output shaft of drive motors 4 connects driving worm screw 3, drives worm screw 3 and is meshed with driving worm gear 2; Driving worm gear 2 is fixedly installed on driving splined shaft 1;
Drive on splined shaft 1 and be arranged with hollow spline leading screw 5, be fixedly installed on hollow spline lead screw pair 5 and promote worm gear 6, promote worm gear 6 and be meshed with lifting worm screw 12; Promote the output shaft that worm screw 12 connects lifting motor 11;
Hollow spline leading screw 5 and the coaxial setting of driving splined shaft 1 are provided with the gap between hollow spline leading screw 5 and driving splined shaft 1, make the spinning movement of driving splined shaft 1 and the spinning movement mutually noninterfere of hollow spline leading screw 5;
Be movably set with feed screw nut 7 on hollow spline leading screw 5, feed screw nut 7 is fixedly connected with slide 9;
Drive splined shaft 1 and be arranged in drive case 8, drive splined shaft 1 and be flexibly connected by bearing and drive case 8; An end that drives splined shaft 1 stretches out drive case 8, and feed screw nut 7 and slide 9 are arranged at outside drive case 8;
An end that drives splined shaft 1 is provided with driving bevel gear 10;
Driving bevel gear 10 is flexibly connected by spline and driving splined shaft 1; Can drive driving bevel gear 10 when driving splined shaft 1 rotation and rotate together, and driving bevel gear 10 is when moving up and down along axis direction, driving splined shaft 1 is motionless;
The lower end that drives splined shaft 1 is provided with spline mechanism, be provided with the endoporus that matches with the end surface shape that drives splined shaft 1 on driving bevel gear 10, drive splined shaft 1 being connected by spline winding machine and driving bevel gear 10, driving splined shaft 1 both can drive driving bevel gear 10 and be rotated, and can also slide up and down in the spline endoporus of driving bevel gear 10;
Driving bevel gear 10 is flexibly connected by bearing and slide 9.
Operation principle of the present invention is as follows:
Drive motors 4 drives 2 rotations of driving worm gear by driving worm screw 3, makes to drive splined shaft 1 rotation; Drive splined shaft 1 and drive driving bevel gear 10 rotations, thus can drive installation in the cutter frame mechanism work of slide 9 bottoms;
Lifting motor 11 drives and promotes worm screw 12 rotations, and then makes 6 rotations of lifting worm gear, promotes worm gear 6 and drives hollow spline leading screw 5 rotations, and feed screw nut 7 is moved up and down along hollow spline leading screw 5; Feed screw nut 7 drives slide 9, driving bevel gear 10 and cutter frame mechanism and pumps together, thereby realizes the shave action.
