摘要:
The invention concerns a rolling bearing with a rolling bearing cage (1) having a plurality of rolling element pockets (2) arranged in at least one row to receive at least one row of rolling elements, wherein the rolling bearing cage (1) consists of two lateral rings (3) and a plurality of crosspieces (4) connecting them, between which crosspieces are formed the rolling element pockets (2), and having at least one empty pocket (5). In order to achieve cost-effective manufacture of the rolling bearing cage (1) with the fewest possible changes as compared to a rolling bearing cage fully populated with rolling elements, provision is made according to the invention that the rolling bearing cage (1) is equipped with fewer rolling elements in one row than corresponds to the number of rolling element pockets (2), causing the rolling bearing cage (1) to have empty pockets (5) without rolling elements in the at least one row of rolling element pockets (2). The empty pockets (5) can be implemented in a simple manner by omitting one or more rolling elements, so that storage spaces for lubricant are created. Furthermore, the empty pockets (5) can be formed by targeted shaping in such a manner that a conveying or pumping action is produced in at least one direction of rotation. The invention also concerns a method for producing such a rolling bearing cage.

The invention concerns a rolling element cage (32) made of a metal strip material that is profiled, stamped, cut to length, and bent into a round shape, wherein the ends of the cut-to-length strip sections are joined together by welding. In order to make it possible to influence the lubricant distribution in the bearing and the vibration characteristics of the cage and thus of the overall bearing system, according to the invention the strip section ends (34, 36) are joined together with a predetermined axial offset (a) and/or radial offset (b).

A rolling bearing comprising a rolling bearing cage having a plurality of rolling element pockets arranged in at least one row to receive at least one row of rolling elements, two lateral rings and a plurality of crosspieces connecting the two lateral rings, such that the plurality of rolling element pockets are formed between the plurality of crosspieces, and at least one empty pocket. The rolling bearing cage includes fewer rolling elements in the at least one row than the number of rolling element pockets, such that the at least one empty pocket does not receive a rolling element. A method for producing a rolling bearing cage is also provided.

This invention relates to methods for correlating at least one media path and a signaling session of a packet-switched network and to an implementation of these methods in hardware and software. To overcoming one or more of the limitations and challenges on the correlation of signaling plane and media plane of services, the invention defines a key, which can be used for correlation of media streams and signaling sessions. The invention is based on a signaling probe identifying new services and associated media paths of the media plane by detecting their corresponding signaling sessions and determining for each service a signaling session identifier. The signaling probe registers the signaling sessions and their media paths at a correlation unit using the signaling session identifiers as a key, which allows a media probe to query the correlation unit for respective signaling session identifiers that correspond to media paths detected in the media plane traffic.
摘要:
A gripper device in a sheet-processing machine includes a gripper, a gripper pad associated with the gripper and a first drive for moving the gripper out of an opened position thereof into a closed position thereof. The gripper is cooperatively engageable with the gripper pad for producing a clamping force for holding sheets being processed. A second drive is separately operable from the first drive during a production printing operation of the sheet-processing machine. The first and second drives are operable for positioning the gripper and/or the gripper pad so that clamping faces of one of the gripper and/or the gripper pad are movable by the second drive perpendicularly to clamping faces of the other of the gripper and/or the gripper pad.
