Embodiment
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
Be a kind of bearing changing its resistance value see what provide in Fig. 1, figure, comprise the bearing inner race 100 and bearing outer ring 200, retainer 300, some rolling elements 400 and two conduction end caps 500 be made up of metallic material.
Retainer 300 is arranged between bearing inner race 100 and bearing outer ring 200, some rolling elements 400 to be arranged on retainer 300 and between bearing inner race 100 and bearing outer ring 200, two conduction end caps 500 are inlaid between bearing inner race 100 and bearing outer ring 200 respectively, and are positioned at the position of retainer 300 both sides.
See Fig. 2 to Fig. 4, conduction end cap 500 comprises the first conductive ferrule 510 and is arranged on the second conductive ferrule 520 outside the first conductive ferrule 510.
The inner ring surface of the first conductive ferrule 510 and outer ring surface respectively with the outer circumferential face of bearing inner race 100 and the inner peripheral surface close contact of bearing outer ring 200.
The inner ring surface of the second conductive ferrule 520 and the outer circumferential face close contact of bearing inner race 100, the outer periphery fold inward of the second conductive ferrule 520 forms an annular resilient contacting part 521.Annular resilient contacting part 521 is made up of some arc elastic unit 521a, is provided with gap between two adjacent arc elastic unit 521a.Certain gap is left between the outer circumferential face 521b of annular resilient contacting part 521 and the inner peripheral surface of bearing outer ring 200, when bearing rotates, annular resilient contacting part 521 outwards produces resiliently deformable under the influence of centrifugal force, its outer circumferential face 521b is formed with the inner peripheral surface of bearing outer ring 200 and contacts.When the rotating speed of bearing is faster, the elastic deformation amount that annular resilient contacting part 521 outwards produces under the influence of centrifugal force is larger, it is higher that its outer circumferential face 521b and the inner peripheral surface of bearing outer ring 200 form the tightness contacted, the resistance value produced is also larger, otherwise, when the rotating speed of bearing is slower, the elastic deformation amount that annular resilient contacting part 521 outwards produces under the influence of centrifugal force is also less, it is lower that its outer circumferential face 521b and the inner peripheral surface of bearing outer ring 200 form the tightness contacted, even do not formed with the inner peripheral surface of bearing outer ring 200 and contact, thus the resistance value produced is less.
In addition, in order to ensure when elastic strain occurs annular resilient contacting part 521 under the influence of centrifugal force, its outer circumferential face 521b is formed better with the inner peripheral surface of bearing outer ring 200 and contacts, thus the outer circumferential face of annular resilient contacting part 521 is arranged a cylndrical surface, the inner peripheral surface of bearing outer ring 200 is a cylndrical surface towards the part of annular resilient contacting part 521.
In order to ensure the sealability of bearing, see Fig. 5 and emphasis composition graphs 1, the inner side being positioned at two guiding end caps 500 between bearing inner race 100 and bearing outer ring 200 is respectively arranged with a bearing sealed ring 600.
More than show and describe basic principle of the present invention and major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
