Turning Bearing Separator with Crisscrossed Concavities
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing angular-contact roller bearings require significant time and effort to assemble due to the need for precise control of separators between rollers, as they can only be inserted in one direction, limiting assembly efficiency and increasing the risk of incorrect posture.
Innovation Solution
A turning bearing with a separator design featuring concaved surfaces in a crisscrossed relation, allowing the separator to be installed in either direction and ensuring correct posture, even when loaded at 90 degrees relative to the rollers, with a through-hole serving as a lubricant reservoir to facilitate easier assembly and reduce friction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the separator is designed with concaved surfaces in a crisscrossed relation, then the ease of assembly is improved, but the device complexity increases
Solution Approach 1:
The separator employs asymmetric concaved surfaces arranged in a crisscrossed pattern, where the concavities are positioned at specific angles relative to each other. This asymmetric design allows the separator to be inserted in multiple orientations (0 degrees or 90 degrees relative to the rollers) while maintaining proper contact with the rollers, eliminating the need for precise orientation control during assembly.
Solution Approach 2:
The invention introduces a new dimensional aspect to the separator design by adding concaved surfaces that extend in multiple directions rather than a single plane. The crisscrossed arrangement of concavities creates a three-dimensional contact interface with the rollers, enabling multi-orientation compatibility and simplifying the assembly process from a single-dimension alignment requirement to a multi-dimension tolerant design.
2Loss of time
If the separator can be installed in either direction, then the loss of time is reduced, but the manufacturing precision requirements increase
Solution Approach 1:
The separator employs asymmetric concaved surfaces arranged in a crisscrossed pattern, where the concavities are positioned at specific angles relative to each other. This asymmetric design allows the separator to be inserted in multiple orientations (0 degrees or 90 degrees relative to the rollers) while maintaining proper contact with the rollers, eliminating the need for precise orientation control during assembly.
Solution Approach 2:
The separator is divided into multiple functional surfaces: first concaved surfaces for contacting rollers in one orientation, second concaved surfaces for contacting rollers in the perpendicular orientation, and a through-hole for lubrication. This segmentation allows each surface to be optimized for its specific function while collectively providing multi-orientation compatibility, reducing assembly time without requiring excessive overall precision.
3Object-affected harmful factors
If the separator has a through-hole for lubrication, then the friction is reduced, but the structural strength decreases
Solution Approach 1:
The separator incorporates a through-hole that creates a porous or permeable structure, allowing lubricant to pass through and reach the contact surfaces between rollers and the separator. This porous design reduces friction by ensuring adequate lubrication while maintaining structural integrity through the careful positioning and sizing of the through-hole, which is located to minimize impact on the separator's load-bearing capacity.

AI summary
The turning bearing has a separator whose leading and trailing sides are concaved to fit over circular rolling surfaces of the rollers to provide concavities where concaved surfaces lying either in parallel with and in perpendicular to the axis of the roller. The rollers fit in the separator in either of two different directions. The separator can be easier installed into the raceway through a loading hole without the posture of the separator in mind. The separator has a quadrilateral in a transverse cross-section perpendicular to a traveling direction of the separator of which a peripheral surface is in opposition to the outer ring and the inner ring. The separator has a center through-hole. The concaved surfaces in the separator are contoured in arced or curved profiles and bulge gradually closer to a circular edge of the through-hole to form arcing bulges at bottoms of the curved surfaces.
