Problems solved by technology

Another disadvantage is that the packing part of the closed raceway must be fixed, which in turn makes the radial expansion of the bearing ring larger
Another disadvantage is that the packing defines the distance between the two raceways, since the farther the raceways are radially apart, the greater this distance must be

Embodiment Construction

[0018] To illustrate the prior art, first refer to Figure 5 . The double-row skewed roller bearing shown here consists of outer bearing rings 1 and inner bearing rings 2 which are arranged concentrically to each other around a bearing axis 6 . Cylindrical rolling bodies 3, 4 roll between the two bearing rings 1, 2. The rolling bodies 3 , 4 are fed to the bearing through filling openings (not shown) in the inner bearing ring 2 , so that the bearing is filled with the rolling bodies 3 , 4 . After the filling process, the filling opening is closed with a plug 7 which must be fixed again in the inner bearing ring 2 using the fastening screw 5 . Obviously, when the distance L between the two rolling elements 3, 4 along the axial direction (according to Figure 5 As L) becomes larger, the stuffing element 7 must also be adapted accordingly. The invention should therefore now enable a simplified design of such a bearing.

[0019] Such as figure 1 As shown, the skewed roller be...

Abstract

This invention refers to a bi-serial inclined roller bearing (8), including an outer bearing ring (9) and an inner bearing ring (10) as well as a number of cylindrical rolling bodies (11, 12) arranged in two rows between two bearing rings (9, 10); the rolling bodies are mutually arranged to an O-arrangement and roll on tracks (14, 15, 23, 24) extending by the means of inclining an angle (Alpha) with a bearing axis (16). The solving method according to the invention is: each row (11, 12) of rolling bodies (11, 12) has filling openings (26, 27) located outside the tracks (14, 15, 23, 24), whose central axis (28, 29) are extension lines of rotation axes (30, 31) of the rolling bodies and both filling openings are closed by fill stoppers (32, 33) after filling the rolling bodies (11, 12).

Description

technical field [0001] The invention relates to a double-row oblique roller bearing, which consists of an outer bearing ring and an inner bearing ring and a plurality of cylindrical rolling bodies arranged side by side in two rows between the bearing rings, the rolling bodies are arranged in a O-shaped structure and rolls on a raceway extending at an angle oblique to the bearing axis. Background technique [0002] If double row angular contact ball bearings or crossed roller bearings cannot transmit the necessary forces (life) or moments (overturning strength) in the same construction space, then double row inclined roller bearings are always used. A typical implementation of this type of bearing is found on page 96 of SKF catalog 3135T "RKS swivel bearings". This double row swivel bearing has a one-piece bearing ring. The rollers made of rolling bearing steel are inserted into the bearing through common insertion openings in the bearing rings, the insertion openings being...
