Vibratory Conveyor Mounting Plates for Stress Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vibratory conveyors are susceptible to vibration-induced structural damage due to cyclic stresses generated by vibratory motors, which can lead to fatigue cracks and other structural issues, particularly in thin or welded components.
Innovation Solution
A vibratory conveyor design featuring a base frame with flexible springs and solid mounting plates integrated within tubular sidewall segments, along with a force-balancing member and strategically placed welds to distribute and absorb cyclic stresses, enhancing the conveyor's ability to withstand high vibratory loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If thin components or welded joints are used in the base frame, then device complexity and manufacturing ease are improved, but structural strength and reliability deteriorate under cyclic vibratory loads
Solution Approach 1:
The patent changes the geometric parameters of the base frame by incorporating tubular sidewall segments with integrated mounting plates, where the plates extend into the tubular chambers. This structural parameter modification allows the frame to withstand higher cyclic stresses without requiring thicker components or additional welds, thereby maintaining ease of manufacture while improving structural strength.
2Strength
If mounting plates are positioned away from the motors, then stress concentration near motors is reduced, but mounting precision and alignment become more difficult
Solution Approach 1:
The mounting plates are nested within the tubular sidewall segments, with the plates extending into the tubular chambers. This nesting arrangement positions the mounting plates optimally relative to the motors, distributing stresses away from critical motor mounting locations while maintaining precise alignment through the integrated tubular structure that guides plate positioning.
3Reliability
If the base frame is designed to withstand high cyclic stresses, then reliability and duration of action are improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The mounting plates and tubular sidewall segments are merged into a single integrated component rather than separate parts. This combination eliminates the need for additional fasteners or alignment features, reducing device complexity while maintaining the structural integrity needed to withstand high cyclic stresses and improve reliability.
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 design effectively reduces the risk of crack formation near the motors and allows the base frame to withstand higher cyclic stresses, improving the conveyor's durability and reducing the need for counterweights, while isolating high stresses to prevent structural damage.
Implementation Method 1
The base frame is connected to the pan with a flexible spring
Implementation Method 2
The base frame includes a first side that includes a tubular sidewall segment having an inner chamber and a first mounting plate for mounting a vibratory motor. An end of the first mounting plate is disposed within the inner chamber.
