Problems solved by technology

However, the pressure in the inner area A' decreases, and the lubricating oil in the outer area B' is drawn into the inner area A', so it is assumed that no effect can be expected for the reduction in the amount of lubricating oil flowing in the bearing.

Embodiment Construction

[0015] About the form for carrying out this invention, it demonstrates based on an Example.

[0016] according to Figure 1 ~ Figure 4 A tapered roller bearing according to Embodiment 1 of the present invention will be described. Such as figure 1 and figure 2 As shown, the tapered roller bearing includes an inner ring 10 , an outer ring 30 , a plurality of tapered rollers 40 and a cage 50 .

[0017] The inner ring 10 is formed in a cylindrical shape having a center hole 11 penetrating through the center, and a tapered inner ring raceway surface 13 is formed on the outer peripheral surface. A large flange portion 14 is formed adjacent to the inner ring raceway surface 13 on the outer peripheral surface of the large-diameter end portion of the inner ring raceway surface 13 of the inner ring 10 . A small flange portion 20 is formed adjacent to the inner ring raceway surface 13 on the outer peripheral surface of the end portion on the small diameter side of the inner ring ra...

Abstract

The invention provides a tapered roller bearing. Tapered roller bearings consist of an inner ring, an outer ring, multiple tapered rollers and a cage. The cage includes: two annular portions on a large-diameter side and a small-diameter side; wall portions forming both axial ends of the cavity; and a plurality of column portions. Contains a pressure difference reducing unit that reduces the pressure in the inner area including the smallest inner diameter portion of the outer ring raceway surface of the outer ring and the outer peripheral surface and shaft including the small diameter side annular portion of the cage The pressure difference in the outer region including the boundary between the outer end faces.

Description

[0001] The entire contents of the specification, drawings, and abstract included in the disclosure of Japanese Patent Application No. 2014-046157 filed on March 10, 2014 are incorporated herein by reference. technical field [0002] The present invention relates to tapered roller bearings. Background technique [0003] Conventionally, in tapered roller bearings, for example, known Figure 6 A tapered roller bearing of a structure including an inner ring 210 , an outer ring 230 , a plurality of tapered rollers 240 and a cage 250 is shown. A tapered shaft-shaped inner ring raceway surface 213 is formed on the outer peripheral surface of the inner ring 210 . The outer ring 230 is disposed concentrically with the inner ring 210 on the outer peripheral side of the inner ring 210 , and has a tapered outer ring raceway surface 231 formed on the inner peripheral surface. Tapered rollers 240 are rotatably arranged in an annular space between inner ring raceway surface 213 and outer ...
