Abstract
The utility model particularly discloses a sliding bearing of a magneto-fluid lubrication arc cavity. A plurality of grooves are arranged on the outer wall of the sliding bearing; an annular magnet is arranged inside each groove, and is matched with each groove; the annular magnets are separated through permanent magnet spacers, and the annular magnets and the lateral walls of the grooves are separated through permanent magnet spacers; arc cavities are arranged on the inner wall of the sliding bearing; communicated holes are arranged between the outer wall of the sliding bearing and the arc cavities; the four arc cavities are symmetrically distributed inside the inner walls of the annular magnets; the four annular magnets are respectively distributed at the both ends of the outer wall of the bearing; and the two annular magnets are respectively arranged at each one end of the outer wall of the bearing. The lubrication property and the friction and wear resistance property can be entirely improved; the working efficiency of the bearing is improved; and the service of the bearing is prolonged.
Description
Technical field
The utility model is specifically related to the lubricated circular arc chamber of a kind of magnetic fluid sliding bearing.
Background technique
The bearing that sliding bearing is worked under sliding friction.Sliding bearing stable working, reliable, noiseless.Under the liquid lubrication condition, the undeveloped life of the lubricated oil content of slidingsurface directly contacts, and can also reduce frictional loss and surface abrasion greatly, and oil film also has certain vibration absorption ability, but the starting friction resistance is bigger.And present sliding bearing bearing capacity is poor, and lubricant oil is revealed easily, and power consumpiton is many, and the lubricated maintenance inconvenience expends oiling agent, usually because leakage of lubricant causes bearing failure, even can bring enormous economic loss.
The content of model utility
For solving the shortcoming that prior art exists, the utility model specifically discloses the lubricated circular arc chamber of a kind of magnetic fluid sliding bearing.
The technical solution adopted in the utility model is as follows:
The lubricated circular arc chamber of a kind of magnetic fluid sliding bearing, be provided with a plurality of grooves at described sliding bearing outer wall, being provided with toroidal magnet in groove is mated, between the described toroidal magnet, separate by the permanent magnet spacer ring between toroidal magnet and the recess sidewall, be provided with the circular arc chamber at described sliding bearing inwall, and be provided with the hole of connection between sliding bearing outer wall and the circular arc chamber.
Described circular arc chamber has four, is symmetrically distributed on the inwall of sliding bearing.
Described toroidal magnet has four, is distributed in the two ends of bearing outer wall, and each two at an end.
The beneficial effects of the utility model are: after increasing the circular arc chamber, the thickness of magnetic fluid lubricating film increases, and pressure reduces, and bearing capacity increases, and easier formation elastohydrodynamic lubrication reduces fretting wear; Under the magnetic field of toroidal magnet cooperated, the running fix of control magnetic fluid made oiling agent firmly remain on sliding bearing inside, and what do not leak is lubricated.Improve bearing lubrication and friction and wear behavior on the whole, improved the working efficiency of bearing, prolonged the life-span of bearing.
