Embodiment 1
[0038] Embodiment 1, possesses the implementation situation of magnetic drive and electric drive at the same time:
[0039] An ultra-high-speed bearing with a driving function, comprising a primary bearing inner ring 1, a primary bearing rolling element 2, a common bearing ring 3, a secondary bearing rolling element 4, and a secondary bearing outer ring 5;
[0040] The rolling body 2 of the primary bearing is located between the inner ring 1 of the primary bearing and the common bearing ring 3, and the common bearing ring 3 is located outside the rolling body 2 of the primary bearing, forming a primary bearing; the inner ring 1 of the primary bearing is installed with the A permanent magnet group 6;
[0041] The secondary bearing rolling body 4 is located between the shared bearing ring 3 and the secondary bearing outer ring 5, and the shared bearing ring 3 is located inside the secondary bearing rolling body 4, forming a secondary bearing; the shared bearing ring 3 is equippe...
Embodiment 2
[0054] Embodiment 2, in the specific case where the bearing weight and structure requirements are high, the second permanent magnet group may not be provided, and the rotation of the secondary bearing is all driven by the electromagnet 8, that is, the implementation of only electric drive:
[0055] An ultra-high-speed bearing with a driving function, comprising a primary bearing inner ring 1, a primary bearing rolling element 2, a common bearing ring 3, a secondary bearing rolling element 4, and a secondary bearing outer ring 5;
[0056] The rolling body 2 of the primary bearing is located between the inner ring 1 of the primary bearing and the shared bearing ring 3, and the shared bearing ring 3 is located outside the inner ring 1 of the primary bearing, forming a primary bearing;
[0057] The secondary bearing rolling body 4 is located between the shared bearing ring 3 and the secondary bearing outer ring 5, and the shared bearing ring 3 is located inside the secondary bearin...
Embodiment 3
[0067] Embodiment 3, in the specific case where the bearing speed is fixed, an electric drive mechanism may not be provided, and by rationally setting the number of permanent magnets and the magnetic strength of the magnets in the first permanent magnet group and the second permanent magnet group 7, the primary bearing and The rotational speed between the secondary bearings, so that the rotational speeds of the primary and secondary bearings can be reasonably superimposed; that is, the implementation with only magnetic drives.
[0068] An ultra-high-speed bearing with a driving function, comprising a primary bearing inner ring 1, a primary bearing rolling element 2, a common bearing ring 3, a secondary bearing rolling element 4, and a secondary bearing outer ring 5;
[0069] The rolling body 2 of the primary bearing is located between the inner ring 1 of the primary bearing and the shared bearing ring 3, and the shared bearing ring 3 is located outside the inner ring 1 of the p...
