Mute barbell roller bearing

Abstract

The invention relates to a mute barbell roller bearing which has a structure support technology that is characterized in that the external dimension standard of the mute barbell roller bearing is in line with the technical standard of an international general roller bearing of international standardization organization (ISO). The mute barbell roller bearing is formed by correspondingly matching an inner sleeve ring formed by two separated rings 1, a row of barbell rollers 3, an outer sleeve ring 2 and an invisible retainer 4. The invention aims at solving the technical problem that the traditional N-type series cylindrical roller bearing is not capable of thrusting. The mute barbell roller bearing has the most remarkable selling points that (1) the dynamic flexibility is improved by 20%; (2) the jump noise is reduced by 5-14 decibels (dB); (3) the rotating speed is accelerated by 12-30%; (4) the loading capacity is increased by 30-50%; (5) the safety factor is increased by 2%; (6) a sealing cover can be arranged on the mute barbell roller bearing; (7) axial thrust capability is improved by 70%; and (8) the servo life is prolonged by 14-30%, therefore, the mute barbell roller bearing is a three generation leading edge innovative technology product which is economical and environment-friendly.

Description

technical field [0001] A silent barbell roller bearing, which is the only technical function of the same type N cylindrical roller bearing in the world with axial thrust capability and a sealing cover. It is used in the same field of optomechanical integration as the first generation of sliding shoe bearings and the second generation of rolling element bearings; its application range is wider than that of the previous two generations of traditional bearings. Background technique [0002] In the 21st century with the rapid development of global industrial technology, industries in various countries generally use traditional sliding shoe bearings and rolling element bearings as dynamic journal bearings. The first generation of sliding shoe bearings; it has been used by humans for more than 5,000 years. The structural support technology of this traditional sliding shoe bearing is characterized in that: the rotor journal and the stator shoe seat are relatively matched to form a...

AI Technical Summary

Problems solved by technology

Regardless of the structure type of traditional rolling element bearings, the structural support technology is characterized by: ①It is not suitable to discharge impurities of lubricating oil in the equipment, and the noise is large; ②The bearing raceway cannot be cleaned, and the installation angle (alignment is not center ) deviation cannot be overcome; ③ it is not suitable to return to the emergency brake and reverse, the rollers are easy to break the retainer teeth; ④ the axial momentum of a single roller is large, and the retention of the roller running on the side of the gear cannot be overcome; ⑤ the load-bearing capacity is limited
