The present invention is achieved through the following technical solutions：A kind of high-accuracy bearing, including bearing inner race and bearing outer ring, the bearing inner race outer wall is provided with the first ball grooves, the bearing outer ring inwall is just provided with the second ball grooves to the first ball grooves, more than one ball is installed in the first ball grooves and the second ball grooves, the lower surface opening of the second ball grooves, the bottom part ring of bearing outer ring is provided with a circle draw-in groove around the circle of bearing outer ring bottom one, thickness of the thickness of the bearing outer ring less than bearing inner race, the bottom of the bearing outer ring sets a dismountable support base, the bottom surface of support base is concordant with the bottom surface of bearing inner race, the upper end of support base offsets with the bottom of ball, connecting shaft is installed on bearing inner race.
As preferred technical scheme, the support base includes a base, the lower surface of base is concordant with the bottom surface of bearing inner race, the upper surface of the support base just sets one and encloses clasp to groove position, clasp is buckled into the circle draw-in groove opened up in bearing outer ring bottom surface, the upper surface of the base is provided with the first support ring and the second support ring, and first support ring is arranged side by side with the second support ring, and the upper surface of the first support ring offsets with the upper surface of the second support ring with the lower surface of ball.
Used as preferred technical scheme, first support ring is arranged in the opening that the second ball grooves lower end opens up.
Used as preferred technical scheme, first support ring is circular arc concave surface with the upper surface of the second support ring, and the radian of circular arc concave surface is identical with the radian of ball.
Used as preferred technical scheme, first support ring sets a material collecting tank with the second support interannular.
It is interference fit as preferred technical scheme, between the clasp and draw-in groove.
The beneficial effects of the invention are as follows：Simple structure of the present invention, one support is carried out to the bottom of ball by support base, after supporting seat supports, ball is not in situation about dropping, and the dismounting of ball is more convenient, can at any time change ball, ensure bearing overall precision, and the dust on ball can be dropped into material collecting tank, do not interfere with and normally use, using more accurate.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, the accompanying drawing to be used needed for embodiment or description of the prior art will be briefly described below, apparently, drawings in the following description are only some embodiments of the present invention, for those of ordinary skill in the art, on the premise of not paying creative work, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is overall structure diagram of the invention.
Specific embodiment
All features disclosed in this specification, or disclosed all methods or during the step of, in addition to mutually exclusive feature and/or step, can combine by any way.
This specification（Including any accessory claim, summary and accompanying drawing）Disclosed in any feature, unless specifically stated otherwise, can alternative features equivalent by other or with similar purpose replaced.I.e., unless specifically stated otherwise, each feature is an example in a series of equivalent or similar characteristics.
As shown in Figure 1, a kind of high-accuracy bearing of the invention, including bearing inner race 1 and bearing outer ring 2, the outer wall of the bearing inner race 1 is provided with the first ball grooves, the inwall of the bearing outer ring 2 is just provided with the second ball grooves to the first ball grooves, more than one ball 3 is installed in first ball grooves and the second ball grooves, the lower surface opening of the second ball grooves, the bottom part ring of bearing outer ring 2 is provided with a circle draw-in groove around the circle of bearing outer ring bottom one, thickness of the thickness of the bearing outer ring less than bearing inner race, the bottom of the bearing outer ring 2 sets a dismountable support base 6, the bottom surface of support base 6 is concordant with the bottom surface of bearing inner race, the upper end of support base 6 offsets with the bottom of ball 3, connecting shaft is installed on bearing inner race.
Wherein, support base 6 includes a base, the lower surface of base is concordant with the bottom surface of bearing inner race, the upper surface of the support base 6 just sets one and encloses clasp 5 to groove position, clasp 5 is buckled into the circle draw-in groove opened up in the bottom surface of bearing outer ring 2, the upper surface of the base is provided with the first support ring 4 and the second support ring 8, and first support ring 4 is arranged side by side with the second support ring 8, and the lower surface of the upper surface of the upper surface of the first support ring 4 and the second support ring 8 with ball 3 offsets.
