Pulser Ring Rib Mounting Structure for Deformation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pulser ring mounting structures are prone to plastic deformation under external forces, requiring thicker designs that increase weight and cost, with limited effectiveness in suppressing deformation.
Innovation Solution
A pulser ring mounting structure featuring a rib extending close to a receiving portion on the hub's outer surface, forming a gap that allows elastic deformation and prevents plastic deformation by abutting on the receiving portion, enhancing rigidity and reducing deformation volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the pulser ring is made thicker to prevent plastic deformation, then deformation resistance is improved, but weight and manufacturing cost increase
Solution Approach 1:
The patent applies local quality by providing a rib structure at specific locations on the pulser ring rather than uniformly thickening the entire ring. The rib is positioned to extend toward the receiving portion on the hub, creating localized reinforcement exactly where deformation resistance is needed during mounting and operation, while keeping other areas of the pulser ring thin to minimize weight.
2Strength
If the pulser ring is made thicker to prevent plastic deformation, then deformation resistance is improved, but manufacturing cost increases
Solution Approach 1:
The rib structure provides localized reinforcement only where needed for deformation resistance, rather than requiring uniform thickening of the entire pulser ring. This selective reinforcement approach reduces material consumption and manufacturing complexity, thereby lowering production costs while achieving the required strength performance.
3Stability of the object's composition
If the rib is positioned close to the receiving portion, then deformation suppression is improved, but mounting precision requirements increase
Solution Approach 1:
The patent incorporates a gap between the rib and the receiving portion as a pre-designed cushioning space. This gap allows for elastic deformation of the pulser ring during mounting and operation, absorbing dimensional variations and positioning tolerances. By providing this deformation buffer in advance, the design reduces the stringency of manufacturing precision requirements while still achieving effective deformation suppression through the rib structure.
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 structure effectively suppresses pulser ring deformation by improving rigidity and allowing elastic deformation, preventing plastic deformation and maintaining the pulser ring's original shape when external forces are removed, while allowing for appropriate mounting without strict dimensional control.
Implementation Method 1
the gap (G) may be set to such a size that when the pulser ring (34) is deformed in an elastic deformation zone, the rib (62) abuts on the receiving portion (70)
