Embodiment Construction

[0019] The invention is a slewing bearing with a V-shaped groove in the inner ring.

[0020] to combine figure 1 , the slewing bearing of the present invention comprises an outer ring 1, rolling balls 2, fin sealing ring 3, inner ring 4, spacer block 5, plug 6 and conical positioning pin 7, an inner raceway is set on the inner diameter end surface of the outer ring 1, and the inner The outer diameter end surface of the ring 4 is provided with an outer raceway, the inner raceway is symmetrical to the outer raceway, and the curvature radii of the inner raceway and the outer raceway both match the radius of the rolling ball 2, and Several rolling balls 2 are installed between the inner raceway and the outer raceway. It is recommended to use four-point contact balls for the rolling balls 2. Spacer blocks 5 are set between adjacent balls 2. The spacer blocks 5 can ensure the safety of the slewing bearing. The rotation accuracy prevents the balls from colliding during rotation and ...

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...
