Roller Bearing Clip for Torque Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Roller bearings face challenges in efficiently transmitting torque due to the positioning of rollers within the roll cage, as the current systems lack effective mechanisms to maintain rollers in a desired position, affecting their performance.
Innovation Solution
A clip system comprising a connection segment, a resilient portion, and an anchor portion is used to position and maintain rollers within the roll cage, where the resilient portion biases the rollers into place by contacting them from one side and the anchor portion is attached to the roll cage, ensuring accurate alignment and retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If rollers are positioned in the roll cage without a positioning mechanism, then the structure is simple, but the torque transmission efficiency deteriorates due to improper roller positioning
Solution Approach 1:
The clip is divided into three functional segments: a connection segment for mounting, a resilient portion for contacting and biasing the roller, and an anchor portion for securing to the roll cage. This segmentation allows each part to perform its specific function optimally while maintaining overall structural efficiency.
Solution Approach 2:
Different portions of the clip have different properties: the connection segment provides structural attachment, the resilient portion provides elastic biasing force, and the anchor portion provides secure mounting. This local differentiation of properties enables the single component to address multiple positioning requirements simultaneously.
2Reliability
If a positioning mechanism is added to maintain rollers in desired position, then torque transmission efficiency improves, but the device complexity increases
Solution Approach 1:
The resilient portion automatically adjusts to maintain optimal roller positioning through its elastic properties. As the roller experiences lateral loads, the resilient portion deflects and provides a restoring force that centers the roller, eliminating the need for complex active control mechanisms.
Solution Approach 2:
The clip utilizes changes in the resilient portion's physical state (elastic deformation) to maintain roller positioning. The resilient portion transitions between different deflection states based on roller position, providing continuous positioning adjustment without mechanical complexity.
3Manufacturing precision
If the resilient portion contacts the roller to bias it into position, then roller alignment improves, but lateral movement increases due to contact forces
Solution Approach 1:
The resilient portion acts as a counterbalancing element that applies a restoring force opposite to any lateral displacement of the roller. When the roller moves laterally, the resilient portion deflects and generates a force that pushes the roller back toward its centered position, effectively counteracting lateral movement.
Solution Approach 2:
The resilient portion provides dynamic adjustment rather than rigid constraint. It allows the roller to move slightly under load while maintaining optimal positioning through continuous elastic adjustment, adapting to varying operating conditions without causing harmful lateral forces.

AI summary
Certain embodiments of the present disclosure describe a clip for biasing and maintaining rollers within an opening of the roller bearing assembly. The clip includes a connecting segment, a resilient portion, and an anchor portion. The clip may be attached to a roll cage with openings for rollers. The resilient portion of the clip extends into an opening and contacts the roller when a roller is received in the opening. The anchor portion is positioned in an adjacent opening and abuts the roll cage.
