Turnable bearing with inner ring provided with V-shaped belt groove

Abstract

The invention discloses a turnable bearing with an inner ring provided with a V-shaped belt groove. The turnable bearing comprises an outer ring (1), a rolling ball (2), a finned seal ring (3), an inner ring (4), an isolating block (5), a plug (6) and a conical locating pin (7). The outer ring (1) comprises an inner raceway body and an installation body and is shaped like an outer stair step. The inner ring (4) comprises a belt body and an outer raceway body and is shaped like an inner stair step. An inner raceway is arranged on the inner raceway body. An outer raceway and an inner threaded hole (4.2) are arranged on the outer raceway body. The installation body is provided with an installation hole (1.1) and the belt body is provided with a V-shaped belt groove (4.1). By the installation hole, the inner threaded hole (4.2) and an inner hole formed in the outer raceway body, the end face of an outer locating ring and the end face of an inner locating ring are on the same side, the use range of the turnable bearing is widened and the use requirements of a matched host machine are met to the highest degree. The structure is novel and unique and the installation is extremely convenient.

Description

technical field [0001] The invention belongs to the technical field of bearings, and in particular relates to a slew bearing with a V-shaped groove on the inner ring. Background technique [0002] The slewing bearing can bear large axial load, radial load and overturning moment at the same time. It is generally composed of outer ring, inner ring and rolling elements. Usually, the outer ring is fixed and the inner ring rotates with the mandrel of the matching main engine. While rotating, the end face of the positioning outer ring and the end face of the positioning inner ring are not on the same side but just opposite. The rolling body is installed in the raceway jointly set by the outer ring and the inner ring. The sealing ring seals the rolling body. The rolling body can be a rolling ball. Can also be cylindrical. [0003] Some mandrels that match the main engine have no rotational force, and must drive the rotation of the inner ring through other transmission parts of...

Problems solved by technology

[0003] Some mandrels that match the main engine have no rotational force, and must drive the rotation of the inner ring through other transmission parts of the matching main engine, and the end face of the positioning outer ring and the end face of the positioning inner ring are just on the same side, so the existing slewing bearings The structural form is unable to meet the use requirements of this type of matching host
