A Double Row Tapered Roller Bearing Bearing Unbalanced Loads

Abstract

The invention discloses a double-row conical roller bearing capable of bearing unbalanced load. The double-row conical roller bearing comprises an inner ring, an outer ring, retainers, a roller and aspacer ring, wherein the retainers which are symmetrically distributed are clamped between the inner ring and the outer ring, the retainers are provided with the roller which is axially distributed, the spacer ring is arranged between the inner ring, and an annular extrusion block is arranged on the spacer ring; annular protrusions are arranged on the annular extrusion block, an annular groove isformed in the middle of the outer ring, threaded holes are formed in the annular groove, and bolts are arranged in the threaded holes; and an annular mounting ring is arranged in the inner ring, and the annular mounting ring is connected with the inner ring through rubber blocks which are axially distributed in a clamped mode. When the outer ring of the double-row conical roller bearing is subjected to unbalanced load, a stress concentration is generated, the positions of the retainers are adjusted continuously, a rolling stress position of the roller in the inner part is changed at the moment, and the stress concentration is generated inside the bearing for a long time to cause early fatigue of the bearing is further relieved; and when the unbalanced load is applied to the annular mounting ring by a shaft, the stress concentration of the inner ring is relieved through the rubber blocks.

Description

technical field [0001] The invention relates to a double-row tapered roller bearing, in particular to a double-row tapered roller bearing capable of bearing unbalanced loads. Background technique [0002] The traditional double-row tapered roller bearing is a symmetrical structure design. The bearing center of the bearing is at the center of the bearing. When the bearing position is at the center of the bearing, the bearing is evenly loaded, such as Figure 5 As shown, but when the bearing position is no longer the center of the bearing, the bearing will be subjected to a certain overturning moment, resulting in eccentric loading, and stress concentration will occur when the bearing is loaded internally, resulting in early fatigue of the bearing. Contents of the invention [0003] The purpose of the present invention is to provide a double-row tapered roller bearing that can withstand unbalanced loads. When the outer ring of the double-row tapered roller bearings of the pre...
