Gear Unit Locking Component for Secure Motor Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transmission units and electric geared motors face challenges in securely attaching electric motors to carrier elements without unintentional loosening or detachment, especially in limited installation spaces, and require complex fastening arrangements that increase space requirements.
Innovation Solution
The integration of a transmission unit with a locking component and a motor locking element that allows for positive or non-positive attachment, featuring a radial stop and a motor locking element with undercuts or segments for secure positioning and locking, enabling flexible assembly and reduced fastening elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex fastening arrangement with multiple fastening elements is used to securely attach the electric motor to the transmission unit, then the reliability of the connection is improved, but the device complexity and space requirements increase
Solution Approach 1:
The locking component and locking unit are integrated into a single unified structure that combines multiple fastening functions. The locking component includes both the radial stop feature and the locking mechanism with undercuts, eliminating the need for separate fastening elements and reducing overall device complexity while maintaining secure attachment
Solution Approach 2:
The locking component serves multiple functions simultaneously: it provides radial stopping to prevent axial displacement, creates positive locking through undercuts to prevent rotational loosening, and enables flexible positioning through segments. This multi-functional design replaces what would traditionally require multiple separate fastening components
2Reliability
If traditional fastening arrangements with multiple fastening elements are used, then the connection security is improved, but the installation space requirements increase
Solution Approach 1:
By integrating the radial stop and locking mechanism into a single locking component that attaches to the motor housing, the invention consolidates multiple fastening functions into one compact element, significantly reducing the installation space required compared to traditional arrangements with separate fastening elements
Solution Approach 2:
The locking component is designed to attach directly to the motor housing and enclose the segments, creating a nested structure where the locking mechanism integrates within the existing motor assembly footprint, minimizing additional space requirements
3Reliability
If the electric motor is designed with larger dimensions and more fastening elements to ensure secure attachment, then the connection reliability is improved, but the adaptability to different installation spaces is reduced
Solution Approach 1:
The segments distributed around the circumference of the locking component enable dynamic adaptation to different installation positions and orientations. The motor can be rotated to align with different installation spaces while the locking component maintains secure attachment through its radial stop and undercut locking mechanism, providing versatility without compromising reliability
4Ease of operation
If a locking mechanism with radial stop and undercuts is used, then the ease of assembly is improved, but the device complexity increases
Solution Approach 1:
The radial stop and undercut locking features are integrated into a single locking component structure rather than being separate elements. This merging reduces the number of parts to assemble while maintaining the simplicity of the assembly process, as the unified structure requires fewer assembly steps despite providing multiple locking functions
