The vertically installed three-row cylindrical roller combined rotating disc bearing retainer disclosed by the utility model effectively achieves the purposes of axial positioning of the axial retainer (1) and radial guiding of the radial retainer (3), meets the requirements of a three-row cylindrical roller combined rotating disc bearing under a working condition of high rotary speed and enhances the working property.
Description
Technical field
The utility model belongs to the design bearing technical field, relates generally to a kind of vertical installation holder for three-row cylindrical roller combination turntable retainer.
Background technique
The mounting type major part of holder for three-row cylindrical roller combination turntable bearing is that level is installed, mainly bear larger thrust load and tilting moment, the radial force of bearing is less, so generally during axial cage adopt fan-shaped segmentation retainer in when design, adopt incorgruous pocket hole to carry out axially locating; Radially retainer adopts aluminum or nylon spacing block.The holder for three-row cylindrical roller combination turntable bearing of vertically installing axially and radially can not use foregoing retainer structure during retainer in design.Because the difference of mounting type, retainer needs to adopt the axially locating solution of considering bearing when design, needs simultaneously to consider the radial directed problem of retainer when work.
The model utility content
For solving the problems of the technologies described above, the purpose of this utility model is to propose a kind of vertical installation holder for three-row cylindrical roller combination turntable retainer.
The utility model adopts following technological scheme for completing above-mentioned purpose:
A kind of vertical installation holder for three-row cylindrical roller combination turntable retainer, described retainer comprises axial cage and retainer radially, described axial cage is two, two described axial cages lay respectively in axial raceway between bearing the first outer ring and bearing inner race, bearing the second outer ring and bearing inner race, and are respectively used to wrap up two row's axial rolling bodies of bearing; In the axial raceway of described radially retainer between bearing the first outer ring, bearing the second outer ring and bearing inner race, and be used for the single radial rolling body of parcel bearing; Some axially locating welding copper billets are set on two described axial cages, and some described axially locating welding copper billets are the retainer circumference uniform distribution vertically, and protrudes from the axial cage upper and lower end face; Radial directed welding copper billet is set on described radially retainer, and described radial directed welding copper billet is positioned on the inner side surface of retainer radially, namely on the face with respect to bearing inner race; Described radially retainer, two described axial cages are integrated formed structure; Two described axial cages and one radially retainer consist of a kind of vertical installation holder for three-row cylindrical roller combination turntable retainer.
Described radial directed welding copper billet is multistage, and the described radial directed of multistage is welded radially retainer circumference uniform distribution of copper billet.
Axial cage in the utility model and radially retainer all adopt monolithic construction, the axially locating welding copper billet that arranges and radial directed welding copper billet efficiently solve the axially locating problem of axial cage and the radial directed problem of retainer radially, simultaneously, well satisfy the working condition requirement of holder for three-row cylindrical roller combination turntable bearing when high rotating speed, improved service behaviour.
