Abstract

Disclosed is a rolling tool which serves for working - in particular rolling smooth - an inner lateral surface of a cylindrical clearance. For this purpose, the rolling tool has at least one rolling body, which is held in the rotatably drivable rolling tool, and can be taken along by said tool on a peripheral path along the inner lateral surface. In this case, the at least one rolling body is inserted into a radial clearance in the rolling tool and can be subjected to a pressurized fluid from the inside to the outside along the radial clearance. According to the invention, the fluid is an aerosol. The aerosol is a fluid mixed with gas and serves for hydrostatic bearing and lubrication. In this case, the amount of fluid required is reduced in comparison with the prior art - on the basis of minimal quantity lubrication (MQL).

Description

technical field

[0001] The invention relates to a rolling tool according to the preamble of claim 1 and to a rolling method. Background technique

[0002] Rolling tools are known for cylindrical clearances, such as connecting rod bores, in which rolling bodies roll on the inner lateral surface of the clearance with an outwardly directed pressing force.

[0003] In patent specification EP1 275 472 B1 a rolling tool of this type is disclosed, in which a ball is pressed by a fluid onto the surface to be rolled. For each sphere there is provided a hydrostatic bearing to which fluid is supplied.

[0004] A disadvantage of this type of rolling tool is considerable leakage and the corresponding loss of fluid or emulsion. Contents of the invention

[0005] In contrast, the object of the present invention is to provide a rolling tool in which fluid or emulsion losses are reduced.

[0006] This object is achieved by a rolling tool comprising the features of claim 1 and a rolling ...
