Rolling Radial Spring Bearing for Low-Wear Vibration Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bearing designs, such as rubber bearings, suffer from high loads leading to increased wear, damage, and noise due to inadequate absorption of shear stresses and friction forces, resulting in a shorter service life and poor vibration damping.
Innovation Solution
A bearing design featuring a radial spring arrangement with a stay extending outward from a base body, allowing for a rolling movement relative to a housing or flange, which reduces wear and noise by maintaining a stationary contact surface and utilizing a high friction force for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the radial spring arrangement is fixedly press-fitted into the housing or flange, then the bearing structure is stable, but the service life is shortened due to high shear stresses and friction forces
Solution Approach 1:
The radial spring arrangement is designed to perform a rolling movement relative to the housing or flange instead of being fixedly press-fitted. The stay extending outward from the base body at an angle enables this rolling motion, transforming the static friction problem into a dynamic rolling contact that significantly reduces shear stresses and extends service life
Solution Approach 2:
The invention replaces the traditional sliding friction mechanism with a rolling movement mechanism. By allowing the contact body to roll along the inner circumference of the housing or flange, the high shear stresses and friction forces are eliminated, resolving the contradiction between structural stability and service life
2Object-generated harmful factors
If the rubber body is fixedly mounted in the flange, then the bearing structure is stable, but noise is generated when the rubber body is subjected to and relieved of load
Solution Approach 1:
The radial spring arrangement with rolling movement provides continuous micro-adjustments during loading and unloading cycles. This dynamic rolling contact prevents the sudden impacts and vibrations that cause noise, while the friction force between the contact body and housing maintains adequate mounting stability
3Object-generated harmful factors
If the rubber body is fixedly mounted in the flange, then the bearing structure is stable, but vibrations are inadequately damped
Solution Approach 1:
The rolling movement of the radial spring arrangement introduces continuous micro-movements that effectively dampen vibrations. The friction force between the contact body and housing provides adequate damping while maintaining mounting stability, resolving the contradiction between vibration damping and mounting flexibility
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The rolling movement of the radial spring arrangement significantly extends the service life of the bearing while minimizing noise and improving vibration damping by maintaining a stationary contact surface and optimizing friction forces.
Implementation Method 1
the radial spring arrangement comprises a stay which extends outwards from the base body at an angle up to perpendicular to the central axis. On the side of the stay facing away from the base body, the radial spring arrangement comprises a contact body which has a radially outwardly facing contact surface. The contact surface of the bearing is press-fitted into a housing, tube or flange in the functional position, and when it is subjected to loads, the contact body can perform a rolling movement relative to the housing, tube or flange by means of the stay and/or by means of the contact bodies.
Implementation Method 2
Sufficient friction can be established between the contact surface and the inner wall of the tube or the inner wall of the flange or housing, such that the rolling movement is performed within the bearing, while the contact surface remains stationary on the inner wall of the tube or the inner wall of the flange or housing.
