Embodiment Construction
[0057] Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0058] The invention provides a magnetic rolling bearing for reducing the balanced radial force of a gear pump, which comprises a magnetized inner ring 1, a magnetized outer ring 2, rolling elements 3 and a cage.
[0059] The magnetized inner ring 1 is annular, and the magnetism of the inner surface of the magnetized inner ring 1 in contact with the shaft is opposite to that of the outer surface of the magnetized inner ring 1 in contact with the rolling element 3 .
[0060] The magnetized outer ring 2 includes a first magnetized component 21, a second magnetized component 22, a first non-magnetized component 23 and a second non-magnetized component 24, the first magnetized component 21 and the second magnetized component 22 are arranged oppositely, and the first non-magnetized component 23 and the second non-magnetized assembly 24 are arranged oppositely, and the first ...

The invention discloses a magnetic rolling bearing for reducing the balanced radial force of a gear pump, which comprises a magnetized inner ring, a rolling body, a cage and a magnetized outer ring assembly. The inner ring is magnetized so that the inner and outer ring surfaces of the magnetized inner ring have different magnetic properties; Two parts, the left and right parts are not magnetized, they are connected by grooves and fixed with bolts, and the four parts are connected alternately to form a complete ring. When installing, place the magnetically different part of the outer ring and the outer ring surface of the inner ring in the high-pressure oil area, and place the same magnetic part in the low-pressure oil area, and reduce a part of the bearing rolling elements through the magnetic repulsion between the inner and outer ring surfaces. The radial unbalanced force it bears slows down the friction and wear of the rolling elements of the bearing, thereby increasing its life.
Description
technical field [0001] The invention relates to a rolling bearing, in particular to a magnetic rolling bearing which reduces the balanced radial force of a gear pump and a method for calculating its life. Background technique [0002] As an important component of the hydraulic system, the external gear pump uses the volume change of the closed volume chamber between the two externally meshing gears and the inner wall of the oil pump to realize oil suction and discharge. External gear pumps have a series of advantages such as simple structure, small size and mass, convenient manufacture, strong self-priming ability, and insensitivity to oil pollution, but there are also radial unbalanced forces that make the bearings of external gear pumps wear more serious problem. Therefore, the present invention improves the structure and researches and develops a rolling permanent magnetic composite bearing that can reduce the radial unbalanced force on the bearing rolling body. Conten...
