Definitions
- the invention relates to a bearing applied to mechanical systems with reciprocating movements and more particularly relates to a bearing with an oscillating ring in which this ring undergoes alternating angular displacement.
- bearings with contiguous rolling bodies in which the rolling bodies are deposited in contact with the raceways at a notch closed by a shutter device.
- the subject of the invention is a bearing which advantageously finds application in the textile industry and whose increased service life. conforming to the standards in force does not require any oversizing of the bearing.
- the invention also relates to a bearing of the type comprising at least, a split outer ring with contiguous edges, a concentric inner ring, raceways formed on one and the other ring and a plurality of rolling bodies deposited at contact of said paths, and in which a lubricant occupies the internal volume of the bearing included between said rings and rolling bodies.
- the internal volume of the bearing is occupied by a ring of lubricant known per se and constitutes an annular chamber which opens in contact with the lateral faces of the bearing and which envelops the rolling bodies until close to their contact with the path of rolling.
- the solid lubricant thus remains in contact with each rolling body and eliminates the phenomenon of evacuation of the greasy lubricant due to the contact pressures of the bearing under load.
- the configuration of the lateral face of the bearing and / or of the lubricating ring improves the retention power of the lubricant and the impermeability of the latter to the penetration of foreign bodies (fibers and water). .
- FIG. 1 is an elevation view of the bearing
- FIG. 2 is an enlarged view of a rolling body in contact with the load with the ring of lubricant according to detail A in FIG. 1,
- FIG. 3 is an example of an embodiment of the lubricating ring
- FIG. 4 is an enlarged view of the contact of a rolling body with the lubricating ring
- FIG. 5 is an elevational view of the embodiment of a bearing cage distribution of the rolling bodies.
- the rolling body bearing 3 has an outer ring 1 and an inner ring 2.
- the rings 1, 2 are deposited concentrically and delimit an annular space receiving the rolling bodies 3 in contact with raceways 5e and 5i carried by the rings 1, 2.
- the rings 1 and 2 are made in the form of rings and the outer ring 1 is mounted as a rotating example and is subjected to a load F directed radially towards its axis of rotation.
- the bearing is assembled as an example
- a radial slot 6 made in the outer ring 1 allows the edges 3a and 6b to be separated, the mounting of the balls 3 between the said rings.
- the approximation of the edges 6a and 6b which follows makes the bearing impossible to dismantle.
- the bearing in horizontal position is previously mounted on a removable waterproof support and rotated around a vertical axis.
- a dose of lubricant 10 is introduced into contact with the upper lateral face 12 of the bearing, the formulation of which corresponds to a solidified mixture of an oil and a resin in the liquid phase.
- the bearing is then closed with suitable tools.
- the bearing tool assembly is then brought to a temperature allowing the solid phase of the lubricant.
- the number and the size of the rolling bodies 3 as well as the internal geometry of the rings are optimal in order to increase the ability of the bearing to dynamic or static loads.
- the internal volume N of the bearing thus constitutes an annular chamber which opens into contact with the lateral faces 12 of the bearing.
- lubricant 10 as defined avoids the use of additional sealing means necessary to retain the lubricant on the one hand, and to prevent the penetration of impurities and liquids in the bearing, on the other hand.
- the volume V is thus filled with a lubricating ring, the rigid sides of which provide protection for the bearing against impurities.
