Cylindrical roller bearing with high axial bearing capacity

Abstract

The invention relates to the technical field of rolling bearings, in particular to a cylindrical roller bearing with high axial bearing capacity, which is used for a main cone guiding support of a main reducer of a drive axle of a truck. The cylindrical roller bearing comprises an outer ring, an inner ring, a full complement cylindrical roller clamped between the outer ring and the inner ring, and a flat check ring arranged on one side of the inner ring and one side of the cylindrical roller. Through the improvement of the strength of the retaining sides and the change of the shape of the retaining side at the contact part of the inner ring of the bearing and the end surface of the roller, the shape of the retaining side at the contact part of the outer ring of the bearing and the end surface of the roller, and the shape of the contacted end surface of the roller, the lubricating condition of the contact area of the retaining side of the inner ring of the bearing and the end surface of the roller and the lubricating condition of the contact area of the retaining side of the outer ring of the bearing and the end surface of the roller are improved to form better elastic dynaflow lubricating, so that the axial bearing capacity can be improved greatly, the breakage of the retaining side of the inner ring can be effectively prevented, and the use failure rate of the product can be reduced.

Description

technical field [0001] The invention relates to the technical field of rolling bearings, in particular to a cylindrical roller bearing with high axial load capacity that can be used for the main cone guide support of the main reducer of the truck drive axle. Background technique [0002] At present, cylindrical roller bearings are generally used in the main cone guide bearings of the main reducer of medium and heavy-duty vehicle drive axles, see Figure 1-Figure 5 shown. This kind of cylindrical roller bearing mainly bears radial load in design theory, and does not bear axial load. However, in actual use, affected by factors such as the processing and assembly accuracy of related parts, the overload of vehicles, and poor road conditions, cylindrical roller bearings often have to bear large axial loads, resulting in cracking of the ribs of the inner ring of the bearing. , The bearing is damaged, and the related parts are damaged, which seriously affects the driving safety of...
