Abstract
The utility model relates to the technical field of the bearing, in particular to a double-row angular contact thrust ball turnplate bearing. The bearing is provided with an outer gear ring and an internal ring. The outer gear ring and the internal ring are correspondingly provided with an upper cambered raceway and a lower cambered raceway, which are symmetrical. Steel balls are placed in the corresponding two cambered raceways. An isolating block is arranged between the two adjacent steel balls. The shape of the end plane of the isolating block contacting with the steel ball is in an arc shape. The part of the internal ring, which corresponds to the steel ball, is provided with an axial hole in which a plug is placed. The plug is fixed with the internal ring through a taper pin. One end of the plug is provided with a cambered groove matched with the spherical surface of the steel ball. By adopting the two rows of steel balls, the utility model has the advantages of high carrying capacity, simple and compact structure and convenient installation and dismantlement and is extensively applicable to the digging machine, the construction machine and other fields.
Description
Technical field
The utility model relates to technical field of bearings, relates in particular to a kind of double angle contacting thrust ball turntable bearing.
Background technique
Turntable bearing is a kind of medium-and-large-sized bearing that can bear the special construction of combined loads such as bigger axial load, radial load and tilting moment simultaneously.Generally speaking, turntable bearing self has mounting hole and oilhole, can satisfy the different demands of all kinds of main frames of work under the various different working conditions, be widely used on the medium-and-large-sized swivel gears such as handling machinery, metallurgical machinery, mining machinery, constructional engineering machinery, harbour machinery and automated assembly line.Require the bearing capacity height especially for the turntable bearing on the heavy machinery, the limit speed height, noise is low, the equipment reliability height, easy installation and removal, present turntable bearing can't satisfy these requirements.
