A tapered bearing

Abstract

The invention relates to the technical field of bearings, and discloses a conical bearing, comprising an inner shell, an outer shell, a cage between the inner shell and the outer shell, and rollers evenly distributed on the cage, and a support extending outward from one end of the inner shell The outer ring wall of the support sleeve is provided with an elastic oil storage cavity with one end fixed to the end of the inner shell, an elastic layer is arranged on the inner ring wall of the inner shell, and a separate oil storage cavity is arranged between the oil storage cavity and the inner shell. The oil injection expansion structure for injecting oil into the elastic layer and the lubricating structure for injecting oil into the outer ring wall of the inner shell are fixed on the end face of the elastic oil storage chamber away from the inner shell. The second extruding plate corresponding to the structure and the third extruding plate dislocated from the oil injection expansion structure and the lubricating structure at the same time, the whole structure is ingenious and simple. Multiple effects.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a tapered bearing. Background technique [0002] Tapered roller bearings are separable bearings. The inner and outer rings of the bearing have tapered raceways. This type of bearing is divided into single-row, double-row and four-row tapered roller bearings according to the number of rows of rollers installed. Type, single row tapered roller bearing can bear radial load and single direction axial load, when the bearing bears radial load, an axial component force will be generated, so when another bearing that can bear axial force in the opposite direction is required To balance; the traditional roller tapered bearing is directly fixed by socket connection during installation, the fixation is extremely weak, and it is easy to fail to install because the diameter of the roller tapered bearing is too large or too small, which is not conducive to the user's use, and has no protectio...

Problems solved by technology

[0004] In the above structure, the second return spring is used to provide the elastic force, so that the semicircular clamping plate clamps the installed rotating rod, and the clamping method is used to replace the traditional direct socket fixing method. When the outside world hits the inner shell of the roller tapered bearing, the rolling The inner shell of the sub-conical bearing squeezes the second return spring. Although this structure can automatically avoid damage caused by the collision between the inner shell of the roller tapered bearing and the installed rotating rod, it cannot protect the rollers at the same time.
