Abstract

The invention relates to the field of machine parts, and provides a novel bearing formed through the combination of a permanent magnet bearing and a roller bearing. The novel bearing comprises an inner ring, an outer ring, a roller and four magnetizers. The novel bearing is characterized in that, like a normally used roller bearing, the roller is mounted between the inner ring and the outer ring; the inner ring and the outer ring are formed through processing permanent magnet steel, provided with axial magnetization, the same in magnetic direction, coaxially arranged, the same in axial length and vertically aligned; the magnetic lines of the magnetic steels of the inner ring and the outer ring are completely and respectively concentrated into gaps between every two adjacent magnetizers through four magnetizers on the two sides of the inner and the outer rings, so as to form the permanent magnet bearing; due to polar repulsions, the inner ring and the outer ring mutually repel, extrusion forces from the inner ring and the outer ring of the roller bearing to the roller can be reduced. Therefore, the friction, the abrasion, the vibration and the noise of the system are reduced, the rotating speed of the bearing is increased, and the service life of the bearing is prolonged.

Description

The combination bearing that Permanent-magnet bearing and roller bearing unite two into one

Technical field

The present invention relates to mechanical parts field, is mainly that Permanent-magnet bearing is united two into one with roller bearing, combined integratedly becomes combined bearing, to improve the properties of bearing.

Background technique

At present, roller bearing is widely used in mechanical device, and its life-span determines the life-span of whole device.The life-span of roller bearing, especially when high speed and ultra high speed running, because the reasons such as mechanical friction, wearing and tearing and vibration, noise are restricted; Permanent-magnet bearing does not have friction and wear, the infinitely permanent running of high speed in theory, but it to the environment using and condition and himself the having relatively high expectations of the aspects such as processing, assembling, mounting process, once do not reach just may lose stable.

As Permanent-magnet bearing and roller bearing are united two into one, form combined bearing, just can overcome shortcoming separately, retain advantage separately, create novel high-performance combination bearing.

Summary of the invention

The object of the present invention is to provide the bearing of a kind of permanent magnet and roller combination, it unites two into one Permanent-magnet bearing and roller bearing, forms novel combined bearing, overcomes Permanent-magnet bearing and roller bearing shortcoming separately, retain advantage separately, the properties such as the rotating speed of raising bearing and life-span.

Accompanying drawing explanation

The object of the present invention is achieved like this: as shown in drawings, the outer ring of roller bearing and inner ring and roller form common roller bearing, but because outer ring and inner ring process by permanent magnetic steel, magnet case A, B, C, D focus on the magnetic line of force respectively again the gap between adjacent two magnet cases, form Permanent-magnet bearing, the stressed of roller bearing reduces like this, and the stability of Permanent-magnet bearing increases.Fig. 1 is structural representation of the present invention.

Embodiment

As shown in Figure 1, between inside and outside circle, as common roller bearing, roller is installed, forms conventional roller bearing; Because outer ring and inner ring process by permanent magnetic steel, and axial charging all, magnetic direction is identical, arranged in co-axial alignment, axial length is identical, consistency from top to bottom, the magnetic line of force of inside and outside circle magnet steel all focuses on respectively the gap between magnet case A and B, C and D via magnet case A, B in inside and outside circle both sides, C, D; Due to homopolar-repulsion, between inside and outside circle, mutually repel, form radial permanent magnet bearing.The extruding force of the inside and outside circle that repulsive force between inside and outside circle has reduced roller bearing to roller, thus friction, wearing and tearing, vibration and the noise of system reduced, improve the rotating speed of bearing, extend the working life of bearing.

Advantage of the present invention, with Permanent-magnet bearing mixing rolling machine bearing, reduces the wearing and tearing of roller bearing, improves the stability of Permanent-magnet bearing, thereby improves the rotating speed of bearing, extends the working life of bearing, creates high performance combination bearing.

Claims

1. by permanent magnet and the combined integrated bearing of roller, by inside and outside circle, roller and 4 magnet cases, formed.It is characterized in that, inner ring and outer ring process by permanent magnetic steel, and axial chargings all, and magnetic direction is identical, arranged in co-axial alignment, and axial length is identical, consistency from top to bottom; The magnetic line of force of inside and outside circle magnet steel all focuses on respectively the gap between adjacent two magnet cases via 4 magnet cases in inside and outside circle both sides.
