Rolling bearing
View Patent ↗A rolling bearing, particularly a slewing connection ( 1 ), comprising an outer bearing ring ( 2 ) and an inner bearing ring ( 3 ) and rolling elements arranged between said outer and inner bearing rings for rolling contact with associated raceways, a stop means for limiting an angle of rotation of the rolling bearing being arranged within the rolling bearing, whereby a first solution offered by the invention, the outer bearing ring ( 2 ) comprises on an inner peripheral surface a recess ( 14 ) which extends in peripheral direction and is limited at two ends by a first stop lug ( 15 ), the inner bearing ring ( 3 ) comprises on an outer peripheral surface a guide groove ( 16 ) which extends in peripheral direction and is limited at two ends by a second stop lug ( 17 ), and a guide element ( 18 ) arranged in the guide groove ( 16 ) connects the inner and outer bearing rings ( 3,2 ) to each other by positive engagement.
1. A rolling bearing as a slewing connection, comprising an outer bearing ring and an inner bearing ring and rolling elements arranged between said outer and inner bearing rings for rolling contact with associated raceways, a stop that limits an angle of rotation of the rolling bearing, the stop being arranged within the rolling bearing, wherein the outer bearing ring comprises on an inner peripheral surface a recess which extends in peripheral direction and is limited at two ends by a first stop lug, the inner bearing ring comprises on an outer peripheral surface a guide groove which extends in peripheral direction and is limited at two ends by a second stop lug, and a guide element arranged in the guide groove connects the inner and outer bearing rings to each other by positive engagement.
2. A rolling bearing according to claim 1 , wherein the guide element is configured as a sliding shoe comprising a connected radially protruding pin which engages into the recess.
3. A rolling bearing according to claim 1 , wherein the recess and the guide groove possess an angular range of <360°.
4. A rolling bearing according to claim 1 , wherein the rolling elements are formed by bearing needle rollers of two oppositely oriented angular contact thrust needle roller bearings comprising thrust washers, a point of intersection of prolonged axes of rotation of the bearing needle rollers being situated in one of the outer bearing ring or the inner bearing ring.
5. A rolling bearing according to claim 4 , wherein the outer bearing ring comprises on an inner peripheral surface, a projection pointing toward the inner bearing ring, which projection forms support surfaces for the angular contact thrust needle roller bearings.
6. A rolling bearing according to claim 4 , wherein the inner bearing ring comprises on an outer peripheral surface, a recess for receiving the angular contact thrust needle roller bearings, into which a screw ring is screwed.
7. A rolling bearing according to claim 4 , wherein at least one of the thrust washers or the needle rollers are subjected to a hardening treatment.
8. A rolling bearing according to claim 1 , wherein the bearing rings are made of a light metal.
9. A rolling bearing according to claim 1 , wherein the rolling bearing is a ceiling support for medical appliances.
10. A rolling bearing as a slewing connection, comprising an outer bearing ring and an inner bearing ring and rolling elements arranged between said outer and inner bearing rings for rolling contact with associated raceways, a stop that limits an angle of rotation of the rolling bearing being arranged within the rolling bearing, wherein the inner bearing ring comprises on an outer peripheral surface a recess which extends in peripheral direction and is limited at two ends by a first stop lug, the outer bearing ring comprises on an inner peripheral surface a guide groove which extends in peripheral direction and is limited at two ends by a second stop lug, and a guide element arranged in the guide groove connects the inner and outer bearing rings to each other by positive engagement.
11. A rolling bearing according to claim 10 , wherein the guide element is configured as a sliding shoe comprising a connected radially protruding pin which engages into the recess.
12. A rolling bearing according to claim 10 , wherein the recess and the guide groove possess an angular range of <360°.
13. A rolling bearing according to claim 10 , wherein the rolling elements are formed by bearing needle rollers of two oppositely oriented angular contact thrust needle roller bearings comprising thrust washers, a point of intersection of prolonged axes of rotation of the bearing needle rollers being situated in one of the outer bearing ring or the inner bearing ring.
14. A rolling bearing according to claim 13 , wherein the outer bearing ring comprises on an inner peripheral surface, a projection pointing toward the inner bearing ring, which projection forms support surfaces for the angular contact thrust needle roller bearings.
15. A rolling bearing according to claim 13 , wherein at least one of the thrust washers or the needle rollers are subjected to a hardening treatment.
16. A rolling bearing according to claim 13 , wherein the inner bearing ring comprises on an outer peripheral surface, a recess for receiving the angular contact thrust needle roller bearings, into which a screw ring is screwed.
17. A rolling bearing according to claim 10 , wherein the bearing rings are made of a light metal.
18. A rolling bearing according to claim 10 , wherein the rolling bearing is a ceiling support for medical appliances.
