Crank Drive Adjustment Mechanism for Conveyed Goods Distributor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conveyance flow distributors require high energy due to excessive starting torque for adjustment motions, leading to high fixed operating costs and complex constructions.
Innovation Solution
A device with a crank drive adjustment mechanism coupled to a mechanical energy storage, such as a spring element, reduces starting torque by converting rotary motion into translational motion, allowing for a lower-rated adjustment drive and simplified energy storage arrangement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a high-rated adjustment drive is used to overcome the starting torque, then the conveying element can be adjusted, but the energy demand and fixed operating costs increase
Solution Approach 1:
The mechanical energy storage is pre-loaded with potential energy before the adjustment motion begins. This preliminary energy storage allows the drive means to utilize the stored energy during the adjustment motion, particularly during the initial phase where highest torque is needed, thereby reducing the energy demand from the main drive and lowering overall energy consumption and operating costs.
2Use of energy by moving object
If a mechanical energy storage in the form of a tension spring is used to support the drive means, then the starting torque is reduced, but the construction becomes more complicated and adjustability is restricted
Solution Approach 1:
The mechanical energy storage in the form of a torsion spring is nested within or integrated with the angle gear mechanism. The torsion spring is arranged to act directly on the angle gear, allowing the energy storage to be compactly incorporated into the existing adjustment mechanism without adding external components that would increase construction complexity or restrict adjustability.
3Power
If the energy storage is coupled to the angle gear, then the energy storage can assist the adjustment drive, but the arrangement requires precise coupling
Solution Approach 1:
The mechanical energy storage is merged with the angle gear by integrating the torsion spring's action directly into the angle gear's rotational mechanism. The torsion spring is arranged to apply torque directly to the angle gear's shaft or axis, combining the energy storage function with the angle gear's existing structure. This merging eliminates the need for separate coupling mechanisms, reducing the precision requirements while maintaining effective power assistance throughout the adjustment motion.

Implementation Method 1
The energy storage consists, in particular, of a spring element, one spring end of which is accommodated in a rotationally fixed fashion and the other spring end of which is connected to and subjects the crank drive to a torque.
