Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the technical solution of the utility model is further elaborated.
Embodiment 1
Present embodiments providing the air-float turntable that a kind of worm and gear drives, it includes turntable 1, hemispheric master
Axle 2, hemispheric air-bearing 3, upper ring air-bearing 4, housing 5, baffle ring 6, connection dish 7, turntable seat
8 and worm and gear drive mechanism.
Described turntable seat is square structure, has transverse slat inside it, and the middle part of described transverse slat offers circular hole.
Described housing is positioned on described transverse slat, and offers the first annular groove on the upper surface of described housing, described
Ring air-bearing it is provided with in first annular groove；Described turntable is arranged on described upper ring air-bearing.
Described worm and gear drive mechanism includes worm seat 12, worm gear 10, worm screw 9, bearing 11 and servo
Motor 13.
Described hemispheric main shaft is fixed on the bottom of described turntable；
Described worm seat is fixed on described turntable seat, and described connection dish 7 is positioned on described worm seat, described
Servomotor is fixed on described worm seat, and described worm screw is coaxially fixed on the output shaft of described servomotor,
And the two ends of described worm screw are rotatablely arranged on described worm seat by bearing；Described worm gear is fixed on institute
State on hemispheric main shaft, and described worm gear matches with described worm screw；Between described hemispheric main shaft and housing
It is provided with hemispheric air-bearing, thus is realized hemispheric main shaft and shell by described hemispheric air-bearing
Rotational support between body.
In the present embodiment, the lower end of described baffle ring is fixed on described turntable seat, and the upper end of described baffle ring is fixed
In the groove of the lower surface of described turntable, the lower surface of the most described turntable offers groove.
It is provided with pore, when accessing pure air, hemispheric air-bearing, upper ring to housing on described housing
Air-bearing forms gas mould by air penetration, floats, turntable, worm gear, hemispheric main shaft entirety when watching
When taking motor driving worm screw rotation, worm screw drives worm gear wheel, makes turntable entirety without frictional rotation.
As can be seen here, the air-float turntable that this worm and gear drives, use worm and gear to drive, the most effectively
Reduce the size of self and take up an area space, and substantially increasing running efficiency.Add and made by air
Turntable axle floats, and substantially increases the precision of turntable.Because the viscosity of air is extremely low, so frictional resistance
The least, improve its rotating speed further.Using air to make turntable axle float, cleannes are high, do not pollute
Environment, noise and vibration are little, more meet the developing direction in China's state-of-the-art technology field.
By said structure, this utility model is made to have the advantage that

Hold support turntable rotary part, form air film by air-bearing effect, rely on pure air to be rotated by turntable
Parts float, make turntable friction-free rotary, it is ensured that the stationarity that turntable rotates, it is to avoid plain bearing pair
The abrasion of rotary shaft, makes turntable running accuracy can reach 0.2 μm.
(2) it uses hemispheric main shaft, can automatic aligning centering, it is to avoid turntable is concentric after having assembled,
Affect running accuracy.Use hemispheric air-bearing, with hemispheric main shaft facing-up, make air film uniform, it is ensured that
Radial direction lift of gas when turntable floats is uniform.
(3) air-float turntable that worm and gear of the present utility model drives is Worm Wheel System.Worm and gear passes
The dynamic deceleration transmission having a characteristic that 1. large speed ratio, compact conformation, save space.2. can steadily pass
Dynamic, noise is the least.3. himself can use self-locking property.If the helical angle of worm screw does not has between gear
Equivalent friction angle big time, worm-drive will start self-locking.
The sequencing of above example only for ease of describing, does not represent the quality of embodiment.
Last it is noted that above example is only in order to illustrate the technical solution of the utility model, rather than right
It limits；Although this utility model being described in detail with reference to previous embodiment, this area common
