Linear displacement bearing structure

Abstract

The invention is a new design of a bearing, especially is a linear displacement bearing structure with a transverse movement function, mainly comprising a inner sleeve and an outer sleeve which are all made of rare-earth material with excellent magnetism and identical polarity which can generate a repulse force. A tiny gap, formed at combination of the inner sleeve and the outer sleeve, are kept constant by repulse force to enable the inner sleeve and the outer sleeve to produce rotation and transverse movement, so as to achieve the purpose that the bearing can generate displacement. Therefore the invention is applicable for the requirement of more structure device, and is applicable for high-speed rotation without generating any abrasion and adding any oil and lubricant, obviously more applicable than traditional bearing by using magnetic effect.

Description

technical field [0001] The invention relates to a bearing structure. Background technique [0002] In traditional mechanical devices, the so-called bearing is combined with the shaft to support it and make the shaft rotate, and it is mainly a ball bearing (such as figure 1 As shown), the ball bearing 1 is mainly composed of an inner ring 11, an outer ring 12, several balls 13 and a retainer 14. The ring body 110 of the inner ring 11 is provided with a concave ring groove 111 at the center outside the ring body 110; while the ring body 120 inner center of the outer ring 12 is correspondingly provided with a concave ring groove 121; as for the retainer 14 is a ring body 14 , a ring edge 141 protrudes inward from its top end, and several concave arc grooves 142 are equidistantly arranged on the ring body. When assembling, first put the inner ring 11 into the ring body of the outer ring 12, and then put the ball 13 into the concave ring groove 111 in the center outside the rin...

Problems solved by technology

[0005] Although the above-mentioned bearing structure has improved compared with traditional bearings, they are limited to the function of rotating the shaft, and cannot have the function of lateral displacement. The inventor and designer are specialized in the work of development and design, and the bearing is only suitable for the use of rotation function. , obviously can't meet the needs, so the determination to reform is germinated, and by virtue of one's own profession and years of work experience, he tried his best to think about the solution. Finally, after several tests, corrections and improvements, the present invention the birth
