Abstract
The utility model relates to a high precision double half outer ring type self-aligning ball bearing, comprising a bearing outer ring, a bearing inner ring, a steel ball and a holder. The bearing outer ring is formed by the outer rings of two single races. Outer ring spacers are arranged between the outer rings of two single races. The outer rings of two single races are adopted and plays are adjusted by the outer ring spacers, so the high precision double half outer ring type self-aligning ball bearing decreases the vibration of the bearing, ensures the operative stationarity of the bearing, raises the running accuracy of the bearing, reduces the weight of the bearing, decreases the starting torque of the bearing, and ensures the consistency of the tracking data of the bearing when the bearing is started and stopped.
Description
Technical field
The utility model relates to a kind of double-row self-aligning ball bearing, particularly a kind of highi degree of accuracy double semi outer rings formula
Selfaligning ball bearing.
Background technique
At present, the double-row self-aligning ball bearing of conventional design is made of single raceway outer ring, a single raceway inner ring and an one retainer, and play is difficult to adjust to a very little value, to reach the preload state.Therefore bearing in use vibrates greatly, galloping, and running accuracy is low.
Summary of the invention
Be difficult to adjust to a very little value in order to overcome double-row self-aligning ball bearing play, can not reach the preload state, bearing vibration is big, and the utility model provides a kind of novel double-row self-aligning ball bearing, improves the bearing running accuracy, realizes the smooth operation of bearing.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of highi degree of accuracy double semi outer rings formula selfaligning ball bearing, comprise bearing outer ring, bearing inner race 3, steel ball 4 and retainer 5, and bearing outer ring is made up of single raceway outer ring 1 and single raceway outer ring 6.Between two single raceway outer rings, be provided with outer ring spacer 2.
Adopt two single raceway outer rings, adjust play by outer ring spacer, play is less than zero (being the preload state) under the axial work loads of 29.4KN, reduce bearing vibration, guaranteed the stationarity of bearing operation, improved the running accuracy of bearing, and employing cast aluminium alloy retainer, alleviate the weight of bearing, reduced the starting torque of bearing, guaranteed the conformity of bearing tracking data when starting and stopping.
The beneficial effects of the utility model are, it is big thoroughly to solve bear vibration, bearing fortune is mainly used in astronomicalc optics technical research field, improved the running accuracy of bearing greatly, guaranteed the accuracy that astronomical telescope is followed the tracks of, and the user in use, and bearing clearance can be adjusted by the reconditioning outer ring spacer.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is an overall structure cross-sectional schematic of the present utility model.
Among the figure: 1. single raceway outer ring, 2. outer ring spacer, 3. bearing inner race, 4. steel ball,
5. retainer, 6. single raceway outer ring.
