Abstract

The invention relates to a rolling bearing mechanism with a three-shaft rotary table. The rolling bearing mechanism comprises the three-shaft rotary table, a flange disc, a rolling bearing, a main base, a rolling motor, a standard bearing, a rolling shaft and a shell, wherein a shell is fixed at the left end of the main base; the outer barrel of the rolling shaft is fixed at the right end of the main base; the rolling shaft is Chinese character 'mountain'-shaped; the rolling motor is arranged in the groove of the rolling shaft; the stator of the rolling motor is fixed with the main base; the rotor of the rolling motor is connected with the inner barrel of the rolling shaft through the standard bearing; the rotor of the rolling motor is fixed with the flange disc; the flange disc is fixed with the inner ring of the rolling bearing; the outer ring of the rolling bearing is fixed with the main base; the three-shaft rotary table is fixed on the inner ring of the rolling bearing in the shell. The rolling bearing mechanism is capable of effectively reducing the radial deflections of the inner ring and the outer ring of the rolling bearing due to the gravity of the three-shaft rotary table, prolonging the service life of the rolling bearing, and improving the accuracy of a rolling motion.

Description

A kind of three-axle table rolling bearing mechanism

Technical field

The invention belongs to three-axle table field, optics cabin, particularly a kind of rolling bearing mechanism of three-axle table, can be applied to optics cabin etc. and require rolling high occasion stably.

Background technology

In order to realize the high easy motion of optics cabin rotating direction, need to use rolling bearing.Housing washer and main basal base are connected, and rolling bearing inner ring and three-axle table are connected.Optics cabin is when rotating direction moves, due to gravity, three-axle table can apply downward gravity to bearing, makes rolling bearing inner ring, outer ring radial beat serious, under this beat state, optics cabin is when being subject to the conditions such as vibration, impact, and rolling bearing meeting accelerated wear test, has a strong impact on useful life and service precision, work long hours and even damage rolling bearing, owing to rolling as outer shroud, also can affect the kinematic accuracy of interior ring, thereby affect the normal work of whole system.

Summary of the invention

In order to overcome the shortcoming of prior art, the invention provides a kind of three-axle table rolling bearing mechanism, it can effectively reduce due to the impact of three-axle table gravity on the radial beat of rolling bearing inner ring, outer ring, increase the useful life of rolling bearing, improve the precision of rolling movement, also can not damage device.

The present invention solves the technical scheme that its technical problem takes: it comprises three-axle table, ring flange, rolling bearing, main basal base, rolling motor, standard rolling bearing, the axis of rolling and housing, the left end stationary housing of main basal base, right-hand member is the urceolus of the axis of rolling fixedly, the axis of rolling is " mountain " shape, in its groove, there is rolling motor, the stator of rolling motor and described main basal base are fixed, the rotor of rolling motor is connected with the inner core of the axis of rolling by standard rolling bearing, rotor and the ring flange of rolling motor are fixed, the inner ring of ring flange and rolling bearing is fixed, the outer ring of rolling bearing and described main basal base are fixed, fixing three-axle table on the inner ring of the rolling bearing in described housing.

The present invention has following advantages: rolling bearing and standard rolling bearing are used in combination, increased the axial distance of motion, and then reduced the radial beat of rolling bearing inner ring, outer ring, because rolling ring is positioned at outer shroud, improved the precision of rolling movement, just guaranteed the kinematic accuracy of interior ring, also increased the useful life of rolling bearing simultaneously.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the present invention is further described.

Fig. 1 is cutaway view of the present invention.

Embodiment

As shown in Figure 1, the present invention includes three-axle table 1, ring flange 2, rolling bearing 3, main basal base 8, rolling motor 11, standard rolling bearing 13, the axis of rolling 14 and housing 4.The left end of main basal base 8 is by the first screw 5 sealing stationary housings 4, right-hand member is fixed by the second screw 9 and the urceolus of the axis of rolling 14, the axis of rolling 14 is " mountain " shape, in its groove, there is rolling motor 11, the stator of rolling motor 11 is fixing with described main basal base 8 by the 3rd screw 10, the rotor of rolling motor 11 is connected with the inner core of the axis of rolling 14 by standard rolling bearing 13, the rotor of rolling motor 11 is fixing with ring flange 2 by the 4th screw 12, ring flange 2 is fixed by the 5th screw 7 and the inner ring of rolling bearing 3, the outer ring of rolling bearing 3 is fixing with described main basal base 8 by the 6th screw 6.Fixing three-axle table 1 on the inner ring of the rolling bearing 3 in described housing 4.

On the inner ring of rolling bearing 3 and outer ring, all have screw hole, rolling bearing 3 is customized specially, can meet environment for use requirement, can effectively reduce again optics cabin axial dimension, is conducive to product Miniaturization Design.

Described main basal base 8 mainly plays the effect of carrying, and main basal base 8 is matched in clearance with rolling bearing 3 outer rings, can guarantee the axiality requirement of rolling bearing 3 and main basal base 8.

Described standard rolling bearing 13 inner rings and the inner core matched in clearance of the axis of rolling 14, can guarantee the axiality of standard rolling bearing 13 inner rings and the axis of rolling 14, the outer ring of standard rolling bearing 13 coordinates with the rotor clearance of rolling motor 11, can meet the outer ring of standard rolling bearing 13 and the axiality of rolling motor 11 rotors.The urceolus of the axis of rolling 14 and main basal base 8 are matched in clearance, can guarantee the axiality of the two.

When giving 11 energising of rolling motor, rolling motor 11 drives the inner ring of ring flange 2, rolling bearing 3, three-axle table 1 to rotate, because each part counterface all has required precision, so moving parts and fixture can meet axiality requirement.Rolling bearing 3 is used in combination with standard rolling bearing 13 simultaneously, has strengthened the axial distance rotating, and has more increased the effect of rolling easy motion.Rolling ring is outer shroud, has improved outer shroud precision, also just can guarantee interior ring precision.
