Embodiment Construction

[0027] Embodiment 1 of the tapered roller bearing of the present invention is as Figure 1-4 As shown: it includes an outer ring 1, an inner ring 2, a roller 3, and a cage 4. The roller 3 includes a large end 31 and a small end 32. The cage 4 includes a The annular recess 41 at the end 32 is arranged along the axis of the roller 3 toward the outside of the bearing. The annular recess 41 includes an oil throwing surface 411 near the outer ring of the bearing, and the oil throwing surface 411 It is inclined toward the outside of the bearing, and the inner edge of the annular recess 41 and the inner ring of the bearing form a flow-limiting channel 5 . The annular recess 41 and the cage 4 are processed from one piece of profile. In this embodiment, the annular recess 41 and the cage 4 are stamped and formed of metal material. The flow-limiting passage 5 is stepped, and the flow-limiting passage 5 includes two drainage sections 51 and a connecting section 52 connecting the two dr...

Abstract

The invention provides a conical roller bearing for a differential mechanism. The conical roller bearing comprises an outer ring, an inner ring, a roller and a retainer, wherein the roller comprises abig end and a small end; the retainer comprises an annular concave part located at the small end of the roller; the annular concave part is arranged toward the outer side of the bearing along the axis of the roller; the annular concave part comprises an oil throwing surface arranged at a part close to the outer ring of the bearing; the oil throwing surface is obliquely arranged toward the outer side of the bearing; and a flow limiting channel is formed through an inner edge of the annular concave part and the inner ring of the bearing. The invention provides the conical roller bearing for thedifferential mechanism, which can prevent excessive lubricating oil from entering the bearing and reduce the extra loss.

Description

technical field [0001] The invention relates to a bearing, in particular to a tapered roller bearing used for a differential. Background technique [0002] Tapered roller bearing is a kind of radial thrust rolling bearing with tapered rollers. This type of bearing is mainly used in high rigidity and continuous operation occasions. It can provide stable performance in limited space and compact layout, so it is often used Used in differentials of automobiles, it usually includes an outer ring, an inner ring, rollers, and a cage for isolating the rollers. The rollers are conical and include a large end and a small end A raceway for roller installation is formed between the outer ring and the inner ring, and oil grooves are provided on the raceway corresponding to both ends of the rollers. Due to the tapered roller bearings, there is an axial direction toward the small end of the rollers. Component force, usually the bearings with two small ends facing each other are used as a ...
