Modular Worm Assembly for Easier Shaft Installation and Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
One-piece worms in motor systems are difficult to install, remove, and repair due to their rigid construction, leading to breakage and maintenance challenges.
Innovation Solution
A modular worm assembly comprising a housing with an exterior thread and an insert with mating clips and tabs that form a continuous exterior thread, allowing for easier attachment and detachment from a shaft, facilitating repair and replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a one-piece worm is used, then the structure is simple and strong, but it is difficult to install, remove, and repair
Solution Approach 1:
The worm is divided into multiple segments: a housing portion and an insert portion that can be assembled together. The housing includes an interior slot that receives the insert, allowing the worm to be disassembled for installation and repair while maintaining structural integrity during operation.
Solution Approach 2:
The insert is nested within the housing structure. The insert fits into the interior slot of the housing, creating a nested configuration where the smaller insert component is contained within the larger housing component, enabling easy assembly and disassembly.
2Device complexity
If a one-piece worm is used, then the structure is simple, but it is difficult to maintain and replace
Solution Approach 1:
The worm assembly is segmented into a housing and an insert, allowing the insert to be independently removed and replaced without replacing the entire worm assembly. This segmentation enables selective maintenance of only the worn insert component.
Solution Approach 2:
The insert is designed as a replaceable component that can be discarded when worn and replaced with a new insert while retaining the housing. This allows recovery and reuse of the housing structure, reducing waste and maintenance costs.

AI summary
A worm is configured to attach to a shaft and turn a worm gear. The worm has a housing is a first exterior thread. An insert mates to the housing and has a second exterior thread. The first exterior thread and the second exterior thread form a continuous exterior thread.
