Description

The invention relates to a tilting segment bearing with tilting segments which can be tilted relative to a bearing base body, with which the tilting segments are integrally connected by at least one web, which serves to represent a solid body joint between the respective tilting segment and the bearing base body. The invention further relates to a method for generating a desired preload or preload of a tilting segment in such a tilting segment bearing.

State of the art

From the German published application DE 10 2017 202 740 A1 a tilting segment bearing with a bearing base body and at least one tilting segment is known, which is connected to the bearing base body via a web.

Disclosure of the invention

The object of the invention is to provide a tilting segment bearing with tilting segments which can be tilted relative to a bearing base body, with which the tilting segments are integrally connected by at least one web, which serves to represent a solid-state joint between the respective tilting segment and the bearing base body, in particular with regard to to improve the function and / or the service life of the tilting segment bearing.

The problem is solved in a tilting segment bearing with tilting segments that can be tilted relative to a bearing base body, with which the tilting segments are integrally connected by at least one web, which serves to represent a solid-state joint between the respective tilting segment and the bearing base body, in that at least one A mechanical adjustment device is assigned to the solid body joints, with which a position of the tilting segment associated with the solid body joint relative to the bearing base body can be changed in a targeted manner in order to realize a desired preload or preload of the tilting segment in the tilting segment bearing. The preload or preload of the tipping segment is also referred to with the English term preload. The preload or preload of the tilting segment is required during operation of the tilting segment bearing in order to maintain a stable function, in particular a desired bearing gap tolerance. The aim of the preload or preload or preload is to ensure a tapering gap between a shaft and the tilting segment. A desired preload can be precisely set with the mechanical adjustment device.

A preferred exemplary embodiment of the tilting segment bearing is characterized in that the mechanical adjusting device comprises a screw means with a screw shaft which extends through a through hole in the web, in particular in a widened web section or in an additional web. This simplifies the assembly of the mechanical adjustment device. The screwing means can be adjustably connected to the solid-state joint of the tilting segment in a simple manner via the through hole in the web.

The screw shaft is preferably aligned in a circumferential direction of the bearing base body. As a result, the gap of the tilting segment bearing can be precisely adjusted by tilting the tilting segments.

Another preferred exemplary embodiment of the tilting segment bearing is characterized in that the through hole in the web, in particular in the widened web section or in the additional web, has an internal thread that is complementary to an external thread of the screwing means. Thus, the position of the tilting segment associated with the solid-state joint can be reproducibly adjusted with the screwing means.

Another preferred exemplary embodiment of the tilting segment bearing is characterized in that the web, in particular the widened web section or the additional web, is arranged in a circumferential direction between two recesses in the bearing base body. This simplifies the placement of the mechanical adjustment device in the bearing base body. The widened web section or the additional web can significantly increase the stability of the bearing base body in the area of the mechanical adjustment device. The web for connecting the tilting segment to the bearing base body can advantageously be made thinner than the widened web section or thinner than the additional web, in order to facilitate a desired tilting of the tilting segment.

Another preferred exemplary embodiment of the tilting segment bearing is characterized in that a counterpart to the screwing means is arranged in one of the recesses in the bearing base body. This provides the advantage that the internal thread described above in the through hole can be omitted.

Another preferred exemplary embodiment of the tilting segment bearing is characterized in that the counterpart to the screw means is a nut. This provides the advantage that for the Realization of the mechanical adjustment device in the tilting segment bearing standard parts can be used, which are available inexpensively.

Another preferred exemplary embodiment of the tilting segment bearing is characterized in that the counterpart to the screw means is a bolt with a through hole, which has an internal thread that is complementary to an external thread of the screw means. The bolt is particularly advantageously arranged essentially axially in the bearing base body. For this purpose, the bearing base body can have a corresponding axial bore. This simplifies the manufacture and assembly of the mechanical adjustment device in the tilting segment bearing.

Another preferred exemplary embodiment of the tilting segment bearing is characterized in that the recesses are designed as through holes in the bearing base body. This simplifies the manufacture of the tilting segment bearing with the mechanical adjustment device. The through holes advantageously extend in the bearing base body in the axial direction. The term axial refers to an axis of rotation of the tilting segment bearing. Axial means in the direction or parallel to the axis of rotation of the tilting segment bearing. Analogously means radially transverse to the axis of rotation of the tilting segment bearing.

Another preferred exemplary embodiment of the tilting segment bearing is characterized in that the recesses in the bearing base body are aligned with the through hole in the web, in particular in the widened web section or in the additional web, and with a mounting recess radially outside in the bearing base body. Aligned means that the recess in the bearing base body is arranged in a straight line with the through hole in the web and with the mounting recess.

Another preferred exemplary embodiment of the tilting segment bearing is characterized in that a screw head of the screw means is arranged in the mounting recess. This simplifies the setting of the desired preload or preload of the tilting segment with the mechanical adjusting device.

A further preferred exemplary embodiment of the tilting segment bearing is characterized in that the mechanical adjustment device comprises an axial screwing means with a screw shaft which extends through a through hole in the web such that one end of the screwing means is accessible in a bearing base body on an end face of the bearing base body. The axial screwing means preferably extends through a through hole provided essentially axially in the bearing base body. The axial screwing means provides the advantage that the installation space is not or only insignificantly impaired radially outside the bearing base body by the mechanical adjustment device.

Another preferred exemplary embodiment of the tilting segment bearing is characterized in that the screwing means interacts mechanically with a counter body, which comprises at least two counter body parts with interacting wedge surfaces or cone surfaces. This enables the desired prestressing or preload of the tilting segment to be realized in a simple manner in the tilting segment bearing on the end face of the bearing base body.

The invention further relates to a mechanical adjustment device, in particular a screwing means, an axial screwing means, a counterpart, and / or a bearing base body for a tilting segment bearing described above. The parts mentioned can be traded separately.

In a method for generating a desired preload or preload of a tilting segment in a tilting segment bearing described above, the above-mentioned object is alternatively or additionally achieved in that the position of the tilting segment associated with the solid-state joint is specifically changed relative to the basic bearing body with the mechanical adjusting device. This considerably simplifies the generation of a desired preload or preload of the tilting segment in the tilting segment bearing.

Further advantages, features and details of the invention emerge from the following description, in which various exemplary embodiments are described in detail with reference to the drawing.
