Double row angular contact ball bearing
A double row angular contact ball bearing includes an outer ring and an inner ring having two axially interconnected ring elements. Two outer raceways are provided on the outer ring, and an inner raceway is provided on each ring element, balls running on the outer and inner raceways in two arrows. A ring section of a ring element protrudes axially beyond the outer ring, and a measuring body is provided on the outer cylindrical lateral surface of the ring section. A measuring device with a measuring means which detects the measuring body is provided on the outer ring, said measuring means being positioned radially adjacently to the measuring body and at a distance thereto across a measuring gap.
1 . A double-row angular contact ball bearing, comprising:
an outer ring and an inner ring having two ring elements axially connected to one another,
wherein two outer raceways are provided on the outer ring and an inner raceway is provided on each ring element, wherein two rows of balls run on the outer and inner raceways, and one of the two ring elements has a ring section that projects axially beyond the outer ring, the ring section is a radially outward-projecting ring flange that at least partially radially overlaps the outer ring; and
wherein a measuring body is provided on an outer cylindrical lateral surface of the ring section, and a measuring device with a measuring means which detects the measuring body is provided on the outer ring, said measuring means being positioned radially adjacent to the measuring body and at a distance thereto across a measuring gap.
2 . The angular contact ball bearing according to claim 1 , wherein the measuring device is arranged on an axial ring surface of the outer ring.
3 . The angular contact ball bearing according to claim 1 , wherein an adapter is provided, via which the measuring device is arranged on the outer ring.
4 . The angular contact ball bearing according to claim 1 , wherein the measuring device is arranged directly on the outer ring.
5 . The angular contact ball bearing according to claim 1 , wherein the measuring device has a housing in which the measuring means is accommodated.
6 . The angular contact ball bearing according to claim 1 , wherein the measuring means is an inductive or optical or magnetoresistive measuring means.
7 . The angular contact ball bearing according to claim 1 , wherein the measuring body is a ring shrunk onto the lateral surface and provided with an angular scale.
8 . The angular contact ball bearing according to claim 1 , wherein the angular contact ball bearing is a rotary table bearing.
9 . The angular contact ball bearing according to claim 1 , wherein the two ring elements are axially connected to one another by connecting screws which are screwed into corresponding receiving bores in the ring elements.
10 . The angular contact ball bearing according to claim 1 , wherein the ring element having the ring section is axially wider than the ring element without the ring section.
