Abstract

A rotatable member (3) has on its outside surface a contoured surface portion (15) which widens conically upwards in diameter, is contiguous with a lubricant storage chamber (14) and extends axially to near a bearing (11) by which the rotatable member (3) is rotatably mounted in a housing (4). Lubricant discharging downwardly by gravity from the bearing (11) returns upwardly along the surface part (15) and reaches a zone which is below the bearing (11) and from which the same takes up lubricant. The bearing (11) is therefore supplied with lubricant during the rotation of the rotatable member (3) so that uniform lubrication in a thin layer is ensured. The mounting is used more particularly in a cap of a cap spinning machine or cap twisting machine.

Dependent claims

A mounting mechanism for a cylindrical member adapted to rotate at high speed around a vertical axis, the mounting mechanism comprising a housing and a bearing means engaged around the member for rotatably supporting the member in an axially vertical orientation in the housing and means for maintaining liquid lubricant within the bearing, the means for maintaining comprising a lubricant storage chamber formed between the housing and the rotatable member for receiving lubricant dripping downwardly, the storage chamber being disposed below the bearing and containing a supply of the lubricant, the rotatable member having a surface element for returning lubricant upwardly from the chamber during rotation of the member, the surface element extending axially along the surface of the member and widening continuously upwardly in diameter to a point of maximum diameter spaced near and below the bearing means;

and further comprising a second bearing means engaged around the rotatable member at a position below the widening surface element, the storage chamber extending between the first and second bearing means, the rotatable member having a second surface element extending axially along the surface of the member beneath the second bearing means and widening upwardly in diameter.

A mounting mechanism for a cylindrical member adapted to rotate at high speed around a vertical axis, the mounting mechanism comprising a housing and a bearing means engaged around the member for rotatably supporting the member in an axially vertical orientation int eh housing and means for maintaining liquid lubricant within the bearing, the means for maintaining comprising a lubricant storage chamber formed between the housing and the rotatable member for receiving lubricant dripping downwardly, the storage chamber being disposed below the bearing and containing a supply of the lubricant for lubrication of the bearing means, and means for delivering lubricant upwards from the storage chamber to the bearing means during rotation of the member within the bearing means;

the means for delivering comprising a surface element extending axially along and around the outside surface of the rotatable member, the surface element widening in diameter upwardly along the outside surface of the rotatable member, and a porous sleeve member extending coaxially around the upwardly widening surface element, the porous member receiving lubricant within the storage chamber and returning the lubricant to the bearing means.
