Auger Gear Shift Mechanism Eliminates Adjustable Linkages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gear shift mechanisms for auger planetary gear drives require adjustable linkages that wear over time, leading to misalignment and potential binding, especially in field conditions where precise adjustments are difficult without proper tools and training.
Innovation Solution
A gear shift mechanism using a hydraulic cylinder to push a rocker arm between gear sets, with a spring-based biasing means eliminating the need for adjustable linkages by ensuring proper alignment through a fixed mounting system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If adjustable linkages are used in the gear shift mechanism, then the mechanism can be set to optimum conditions during manufacture, but the linkages wear over time leading to misalignment and binding
Solution Approach 1:
The patent removes the adjustable linkages entirely from the gear shift mechanism. Instead of having separate linkages that connect the hydraulic cylinder to the rocker arm, the design integrates the rocker arm directly with the hydraulic cylinder mounting, eliminating the wear-prone linkage components that caused misalignment and binding over time.
Solution Approach 2:
The patent applies segmentation by separating the biasing function from the actuation function. The spring biasing means is applied directly to the rocker arm at its pivot point, while the hydraulic cylinder provides pure actuation force. This separation allows each component to perform its specific function without the complexity and wear of adjustable linkages.
2Adaptability or versatility
If adjustable linkages are used in the gear shift mechanism, then the mechanism can be adjusted in the field, but aligning these linkages is difficult without precision measurement tools
Solution Approach 1:
The patent eliminates the adjustable linkages that made field alignment difficult. By removing these linkages entirely and using a fixed mounting system with the hydraulic cylinder, the design achieves proper alignment through manufacturing precision rather than requiring field adjustments by operators without precision tools.

AI summary
An improved gear shift mechanism for an auger gear drive which uses a hydraulic cylinder or other linear force means to push on one end of a rocker arm. This moves the rocker arm and the gear train between a first gear set and a second gear set. A biasing means is applied directly to the rocker arm by a spring or other device. The design eliminates adjustable linkages and the need adjustments in the field and allows for use of a simpler hydraulic cylinder than found in the prior art.
