Parallel Rubber Bushing Bearing for Compact Heavy Load Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conical bearings used for heavy machinery require large space due to their wide dimensions, making them unsuitable for installations with tight transverse space constraints, and existing solutions fail to provide a compact yet effective load-bearing solution.
Innovation Solution
A bearing design featuring two rubber bushings with a vertical axis of rotation, arranged in a functionally parallel connection, with a height-adjustable threaded sleeve fastening device that allows for even load distribution and compact installation, enabling the bearing to be adapted to narrow spaces and supporting heavy loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conical bearings are used to support heavy loads, then the load-bearing capacity is improved, but the installation space required increases significantly
Solution Approach 1:
The bearing is divided into two separate rubber bushings arranged in parallel, each bearing a portion of the total load. This segmentation allows the load-bearing function to be distributed across multiple smaller components rather than requiring a single large conical bearing, thereby reducing the overall installation space while maintaining heavy load support capability
Solution Approach 2:
The bearing design transitions from a single wide conical structure to a vertically arranged parallel circuit configuration. By stacking two rubber bushings vertically and connecting them through a bridge structure, the bearing achieves compact transverse dimensions while maintaining adequate load-bearing capacity through the combined vertical arrangement
2Area of stationary object
If the bearing is designed for compact dimensions, then the installation space is reduced, but the load distribution and assembly precision become more difficult to control
Solution Approach 1:
The two rubber bushings are pre-assembled into a integrated bearing unit with the bridge structure during manufacturing, establishing precise geometric relationships and load paths before installation. This preliminary assembly ensures that the load distribution between the two bushings is optimized and controlled, eliminating assembly errors that would otherwise occur with field installation of compact components
Solution Approach 2:
The two rubber bushings and the bridge structure are merged into a single pre-assembled unit, ensuring that the load distribution geometry is fixed and optimized during manufacturing. This merging eliminates the need for complex field assembly adjustments and ensures consistent load distribution across the compact bearing structure

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 compact bearing design allows for easy installation in tight spaces while maintaining effective load-bearing capabilities, reducing assembly errors and ensuring consistent performance over time by distributing the load evenly across the rubber bushings.
Implementation Method 1
two rubber bushings, each with a vertical axis of rotation... arranged in a functional parallel circuit... each rubber bushing has more compact dimensions than a single conical bearing
Implementation Method 2
the load of the unit to be supported is distributed over the two rubber bushings, meaning that each rubber bushing has more compact dimensions
