Embodiment Construction

[0020] figure 1 A cylindrical roller bearing according to a preferred embodiment of the present invention is schematically shown. The cylindrical roller bearing has an outer ring 1 and an inner ring 3 , which are mutually rotatably supported by cylindrical rollers 5 . A plurality of cylindrical rollers 5 are arranged radially around. The cylindrical rollers 5 are separated from each other by a cage 7 . In an alternative embodiment of the invention, it is likewise possible to use a full complement roller bearing (which has the largest number of rollers and therefore does not use a cage) and give the full complement roller bearing Equipped with rollers according to the invention.

[0021] To guide or guide the cylindrical rollers 5 , the outer ring 1 has ribs 9 and 11 formed on the axial end sides. The ribs 9 and 11 each serve as contact surfaces for the axially adjacent end face 25 of the cylindrical roller 5 and thus guide the cylindrical roller 5 . The inner ring 3 has a...

Abstract

The invention relates to a roller for a roller bearing, wherein the roller bearing has at least one axial thrust surface for the roller, wherein the roller is configured with at least one end thrust section, The end thrust section extends at a predeterminable distance from the center axis of the roller in a curve corresponding to the curve h as far as the chamfered area of ​​the roller, wherein: Among them, x is the distance from the central axis of the roller, h1 and h2 are respectively smaller than the roller diameter Dw, Leff is the effective end radius of the roller, hp is the height of the end section of the roller, and K1 and K2 are constants.

Description

technical field [0001] The invention relates to a roller and a roller bearing. Background technique [0002] A series of roller bearings are known from the prior art, in particular cylindrical roller bearings and tapered roller bearings, in which at least one rolling surface element for the roller is designed with a so-called rib at which At least one outer circular ring-shaped section is provided with which the roller also serves for thrust or abutment during normal operation of the rolling bearing. This section can also be designed as a so-called face pad region (Stirnseiten-verblendungsbereich), adjoining radially outwards a so-called chamfered region and radially inwards adjoining a bevelled region. The remaining end surface of the sub, and the remaining end surface is substantially flat, with or without grooves (slightly concave). [0003] An embodiment of such a padded area is described, for example, in DE 10 230 357 B4, but it has always been suboptimal with regard ...
