Problems solved by technology

In the case of the required rough machining of the cuts, a relatively large proportion of material remains as cutting waste, which is firstly produced in a costly manner and must subsequently be removed or recovered in a costly manner.

Embodiment Construction

[0027] figure 1 A perspective view of a sheet metal strip 1 is shown, which is used for producing raceway tubes. In the exemplary embodiment shown, the metal strip 1 is made of a hardenable rolling bearing steel of the C80M type. The thickness of the metal strip 1 is approximately 1 mm, however, the thickness can be selected differently depending on the size of the outer ring to be produced. exist figure 1 Middle identification: The metal strip has the shape of a parallelogram in cross section, that is to say it has an underside parallel to the upper side and two oblique sides 2 , 3 parallel to one another. In the wound state, the inclined sides 2 , 3 rest against each other, thereby preventing movement. The inclination of the inclined sides 2 , 3 and the width of the sheet metal strip 1 are selected such that in the wound state approximately two helical groove turns are produced per raceway width, thereby having a favorable influence on the running noise. In other embodim...

Abstract

The invention relates to an outer ring (16) for a roller bearing comprising a raceway produced from a ball-and-roller bearing steel. According to the invention, said outer ring (16) is made of a metal strip (1, 5) wound to form a raceway tube (4, 12, 14) 5) and a cladding tube (9, 13, 15, 17) which is connected thereto and which surrounds the raceway tube (4, 12, 14) on the outer side.

Description

technical field [0001] The invention relates to an outer ring for a roller bearing having a raceway made of rolling bearing steel. Background technique [0002] Conventional roller bearings, in particular so-called solid roller bearings, consist of a through-hardened or case-hardened outer ring, which is produced from tube sections, rod sections or forged blanks by machining in order to produce roller bearings. Roads, edges and piercings. Roller bearings of this type with thick-walled outer rings are used, for example, in motor vehicles, and due to the high component number, an optimized outer ring design with respect to load and production costs is accordingly required. [0003] For high temperature applications bearings are used whose rolling elements are manufactured by winding strip onto a mandrel. Rolling rolling elements compensate for thermal expansion at high temperatures. Such a bearing is known from DE3809906A1. There, a bearing is proposed which has several ro...
