Linear magnetic suspension bearing

Abstract

The invention provides a linear magnetic suspension bearing comprising a T-shaped rail, a suspension block, inner magnetic strips, and outer magnetic strips. The T-shaped rail is in a strip shape with a T-shaped cross-section. Two or more inner strip-shaped rails are arranged on the upper surface of the T-shaped tail. A inner strip-shaped rail is arranged on each of the two sides of the T-shape. The inner magnetic strips are arranged in the inner strip-shaped rails. The cross section of the suspension block is an inverted recess. The outer magnetic strips are arranged in the recesses at positiones corresponding to the T-shaped rail. Opposite planes of the outer magnetic strips and the inner magnetic strips are same magnetic poles. The suspension block covers and suspends on the upper part of the T-shaped rail. Paired inner magnetic strips and outer magnetic strips are arranged on sides of the T-shaped rail and the suspension block, such that repulsive force is provided on the sides, and the suspension block suspending on the T-shaped rail is prevented from inclining. With the magnetic suspension of the suspension block, the resistance during running is extremely small, and friction is prevented, such that damage is prevented, and lubrication is not needed. Therefore, application cost is reduced, and pollution is reduced.

Description

Technical field [0001] The invention relates to the field of bearings, in particular to a linear magnetic suspension bearing. Background technique [0002] Linear motion is a very common motion in the operation of mechanical equipment. It can be realized by using a variety of mechanical structures. In order to make it more directional, people often use linear bearings or track bearings to complete it. However, the linear bearing is in surface contact during friction, and its friction resistance is relatively large. The linear bearing is easy to wear, and its material requirements are higher, the price is higher, and the replacement is more expensive than ordinary use. Although most of the track bearings adopt a rolling friction structure, their overall structure is relatively complicated, and the production cost is high. Moreover, the rolling bearings in the track are easily derailed and damaged, and the use cost is also high. [0003] A magnet is an object with magnetism. ...
