Embodiment Construction

[0016] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings:

[0017] The hydrophobic and magnetically lubricated bearing of the present invention is composed of a bearing outer ring 1, bearing balls or rollers 2, a column bearing inner ring 3 and a bearing cover 5 arranged between the bearing inner and outer rings, and the bearing outer ring 1 or bearing inner ring 3 or The material of the bearing cover 5 is set as a permanent magnet, so that a closed magnetic circuit in the direction of N and S poles is always formed between the inner and outer rings of the bearing, and the hydrophobic magnetic grease 4 is set in the inner cavity of the bearing, and the hydrophobic magnetic grease 4 is always in the bearing Among the magnetic fields of the closed magnetic circuit established above. The permanent magnet bearing cover 5 can be set to one side or both sides as required. On the basis of not changing the performance o...

Abstract

The invention relates to a hydrophobic magnetic lubricate bearing and the preparation of hydrophobic magnetic lubricant, without changing present bearing structure, to improve the properties of each part of bearing. It sets the outer ring, sealing cover or inner ring as the permanent magnet, or set several small magnetic blocks at the outer surface of sealing cover to form a closed magnetic line; fills hydrophobic magnetic lubricant inside the inner chamber of bearing to be resistant to the brush of outer water by the magnetic force. The invention uses hydrophobic magnetic lubricate to replace present general lubricate to confirm the lubrication of rolling (or sliding) bearing and prolong the service life with lower cost and wider application.

Description

technical field [0001] The invention relates to a hydrophobic magnetic lubricated bearing and the preparation of the hydrophobic magnetic lubricating grease, which is especially suitable for open-air machinery, mining machinery, large-scale equipment, ships, oil drilling rigs, and field weaponry. Background technique [0002] Bearings are the most commonly used parts in mechanical equipment, and their usage is very large. Because the bearings are affected by various aspects such as speed, temperature and environment, the grease in the bearings is easy to lose under the action of external forces, resulting in damage to the bearings. According to According to statistics, the annual consumption of bearings in the country reaches hundreds of millions of sets. The main cause of bearing damage is the lack of lubrication, especially the bearings in machinery that work in the open air or in contact with water, such as oil field drilling rigs, coal mine und...
