Hole.
A kind of bearing on monitoring device camera lens as described above, it is circumferentially equal on the bearing inner race axial end
Even to be provided with 4 inner rings receiving slotted eyes, the correspondence position on chute on the bearing outer ring is circumferentially uniformly provided with 4 institutes
State outer ring and accommodate slotted eye.
A kind of bearing on monitoring device camera lens as described above, the bearing outer ring is away from the bearing inner race
Direction on be circumferentially uniformly provided with outer ring locating dowel, the bearing inner race on the direction of the bearing outer ring circumferentially
It is uniformly provided with inner ring locating dowel.
A kind of bearing on monitoring device camera lens as described above, the bearing outer ring is away from the bearing inner race
Direction on be circumferentially uniformly provided with 4 outer ring locating dowels, the bearing inner race is on the edge on the direction of the bearing outer ring
Circumferentially it is uniformly provided with 4 inner ring locating dowels.
A kind of bearing on monitoring device camera lens as described above, the position of each outer ring locating dowel with it is each
The position that the outer ring accommodates slotted eye corresponds, and the position of each inner ring locating dowel accommodates slotted eye with each inner ring
Position correspond.
The present invention compared to existing technology, with following features：
1) axial ball is provided between bearing inner race end face and bearing outer ring, between bearing inner race lateral surface and bearing outer ring
It is provided with radial direction ball so that the present invention can be while side and the pressure of end face of load carrier generation, the stress that can be carried
Direction is no longer single；
2) correspondence position on the chute on bearing outer ring is circumferentially arranged with outer ring ball slot rolling, the correspondence on bearing inner race
Position is circumferentially arranged with inner ring ball slot rolling so that when bearing outer ring and bearing inner race are relatively rotated, axial ball and radial direction
Ball can put down between outer ring ball slot rolling and inner ring accommodate slotted eye and inner ring ball slot rolling and outer ring receiving slotted eye between respectively
It is sliding to roll, so that resistance suffered in reducing rotation process；
3) position that the position of each outer ring locating dowel accommodates slotted eye with each outer ring corresponds, each inner ring locating dowel
Position and each inner ring accommodate the position of slotted eye and correspond so that when bearing outer ring and bearing inner race are relatively rotated, outward
The radial direction ball that circle locating dowel is accommodated on slotted eye with outer ring all the time be located at it is same radially, and inner ring locating dowel and inner ring holding tank
Axial ball on hole is located on same axial direction, so as to the side pressure being subject in outer ring locating dowel during rotation is direct
It is transferred on radial direction ball, and the end force being subject in inner ring locating dowel is transferred directly on axial ball so that stress is more
Plus it is balanced, improve and receive force intensity.
