Problems solved by technology

Although some radial-axial support bearings design the cylindrical rollers distributed along the radial circumference into a drum shape, the middle of the rollers is slightly larger than the two ends, so as to minimize the sliding process of the rollers, but it cannot avoid sliding

Embodiment Construction

[0017] The specific structure of the present invention will be further described below in conjunction with the accompanying drawings.

[0018] See attached figure 1 , attached figure 2 As shown, a rolling bearing includes a bearing inner ring 5, a bearing outer ring 4, and rolling elements sandwiched between the bearing and the outer rings 5 ​​and 4, and is characterized in that the rolling elements include a plurality of cylindrical rollers 1 and a plurality of spherical rollers 2, the cylindrical rollers 1 and spherical rollers 2 are arranged at intervals along the same circumference, and a cage 3 is arranged between adjacent cylindrical rollers 1 and spherical rollers 2, The axis line of the cylindrical roller 1 is parallel to the axis line of the bearing, the diameter of the spherical roller 2 is smaller than the diameter of the cylindrical roller 1, and the diameter of the spherical roller 2 is larger than The height of the cylindrical roller 1.

Abstract

The invention relates to a rolling bearing which comprises a bearing inner race, a bearing outer race and a rolling body, wherein the rolling body is sandwiched between the bearing inner race and the bearing outer race; the rolling body comprises a plurality of cylindrical rollers and a plurality of spherical rollers; the cylindrical rollers and the spherical rollers are alternately arranged along the same circumference; a retainer is arranged between each cylindrical roller and each spherical roller which are adjacent; the axial lead of each cylindrical roller is parallel with that of the bearing; the diameter of each spherical roller is smaller than that of the cylindrical roller; and the diameter of the spherical roller is greater than the height of the cylindrical roller. The cylindrical rollers of the invention have the function of radial support, and the spherical rollers have the function of axial support.

Description

technical field [0001] The invention relates to a rolling bearing. Background technique [0002] There are two kinds of common radial-axial support bearings: one is angular contact ball bearings, which can be changed to non-standard thin-walled bearings in order to reduce the volume. The ring is removed, and the roller table is directly made on the outer wall of the supported shaft. However, through the transformation of the above structure, the bearing has become a non-standard bearing, which is not only difficult to manufacture, but also inconvenient to repair after damage. [0003] Another radial-axial support bearing structure is: a circle of cylindrical rollers distributed along the axial circumference (the cylindrical rollers are distributed along the circumference, and the axis line of the roller is along the direction of the bearing axis line), a circle along the Cylindrical rollers distributed radially and circumferentially (cylindrical rollers are distributed alo...
