Specific embodiment
With reference to the accompanying drawing, the present invention is described in detail.
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
It is as shown in Figs 1-4 a kind of embodiment of Multi-axis Machining machine tool high speed high precision turntable of the present invention, a kind of multiaxis adds
Work machine tool high speed high precision turntable, including:Shell 1, be equipped in the shell 1 input gear axle 3, rotate forward driving gearshaft 4,
Invert driving gearshaft 5 and output gear shaft 2, the rotatings forward driving gearshaft 4 and reversion driving gearshaft 5 and meanwhile with input tooth
Wheel shaft 3 is meshed, and the rotating forward driving gearshaft 4 and reversion driving gearshaft 5 are meshed with output gear shaft 2 simultaneously, thus
Keep drive gap during 3 positive and negative rotation of input gear axle minimum, there is input helical gear 31 in the input gear axle 3, it is described
Rotating forward on driving gearshaft 4, there is rotating forward to input helical gear 41 and rotate forward output helical gear 42, on the reversion driving gearshaft 5
With reversion input helical gear 51 and reversion output helical gear 52, there is output helical gear 21 on the output gear shaft 2, it is described
Inputting helical gear 31 and rotating forward input helical gear 41 and reversion input helical gear 51 is in triangle engaging structure, the output helical gear
21 with rotate forward output helical gear 42 and reversion output helical gear 52 be in triangle engaging structure, it is described input helical gear 31 positive work
Make the flank of tooth with rotate forward input helical gear 41 positive working flank be meshed, it is described input helical gear 31 the reverse operation flank of tooth with
The reversion input 51 reverse operation flank of tooth of helical gear is meshed, and the positive working flank of the output helical gear 21 and rotating forward output are oblique
The positive working flank of gear 42 is meshed, and the reverse operation flank of tooth of the output helical gear 21 and reversion export helical gear 52
The reverse operation flank of tooth is meshed, also, when being driven to a direction, there are larger between the flank of tooth that opposite direction does not engage
Gap, in this way in forward direction transmission, reverse drive chain is only servo-actuated, without influencing positive drive chain conveyer, the input gear axle 3 with
Rotating forward between driving gearshaft 4 and reversion driving gearshaft 5 is deceleration transmission, the rotating forward driving gearshaft 4 and reversion transmission
It is deceleration transmission between gear shaft 5 and output gear shaft 2,5 axial end portion of reversion driving gearshaft is provided with compensation mechanism
53, the compensation mechanism 53 is disk spring, is provided with angular encoder on the output gear shaft 2.
The course of work:
When the input gear axle 3 in transmission system rotates in the forward direction, i.e., motor-driven 3 clockwise movement of input gear axle is defeated
Entering gear shaft 3 drives reversion driving gearshaft 5 to do counter-clockwise rotary motion, at this point, the positive flank of tooth of input gear axle 3 and reversion
The positive flank of tooth of driving gearshaft 5 is meshed.Since reversion input helical gear 51 and reversion output helical gear 52 are coaxial, so meeting
It is rotated clockwise with identical speed output shaft 2, at this point, the positive flank of tooth and output helical gear 21 of reversion input helical gear 51
The positive flank of tooth intermesh.The rotating forward input helical gear 41 rotated forward on driving gearshaft 4 and rotating forward output helical gear 42
It is connected with bearing and by flat key, when system rotates in the forward direction, exports the flank of tooth of helical gear 21 and rotate forward output helical gear 42
Flank of tooth positive engagement, output helical gear 21 drives rotating forward output helical gear 42 to do counter-clockwise rotary motion, while it is oblique to rotate forward input
Gear 41 does dynamic with transhipment with respect to the input helical gear 31 of input gear axle 3, that is to say, that when being driven to a direction, instead
There are larger gaps between the flank of tooth that direction is not engaged, and in this way in forward direction transmission, reverse drive chain is only servo-actuated, without influencing
Positive drive chain conveyer.
Due to the adoption of the above technical solution, the beneficial effects of the invention are as follows:Double bevel gear backlash mechanism is used simultaneously
Elimination positive and negative rotation gap, disc spring mechanism compensate wear error automatically and high-precision angular encoder carries out angular coding control,
To guarantee that novel numerical control turntable is provided simultaneously with high speed, four high response, high rotating accuracy and high repetitive positioning accuracy good characteristics.
The advantage that the meshing performance being had again based on Helical gear Transmission is good, registration is big, compact-sized, stable drive, noise are small, so that
Novel turntable is provided simultaneously with the big feature of driving torque.
The foregoing is merely the preferred embodiments of invention, are not intended to limit the invention, it is all this hair spirit and
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within principle.
