Motor Mounting Assembly with Adjustable Threaded Rods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional motor mounting assemblies face challenges in adjusting the position of motors in high-power industrial settings due to expensive castings and reduced thread engagement, leading to mechanical wear and efficiency issues.
Innovation Solution
A motor mounting assembly with a motor base and adjustable fixtures featuring elongate slots and threaded rods, where the motor fastener moves along the slot upon rotation of the adjusting rod, enhancing thread engagement and reducing the likelihood of thread damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional adjustable fixtures are used to mount motors, then motor positioning adjustment is enabled, but the fixtures require expensive castings and have reduced thread engagement
Solution Approach 1:
The fixture is divided into separate components: a mounting base, adjustable arms with independent threaded rods, and motor mounting plates. This segmentation eliminates the need for expensive integrated castings while maintaining adjustment capability. Each component can be manufactured separately using simpler, more cost-effective processes.
Solution Approach 2:
The adjustable arms are designed to nest within the mounting base structure, with threaded rods extending from the base and being received by the arms. This nested arrangement allows for compact design and easy adjustment without requiring complex external mechanisms or expensive moldings.
2Ease of operation
If conventional adjustable fixtures with threaded fasteners are used, then motor position can be adjusted, but the amount of thread engagement is reduced, limiting the force that can be safely transmitted
Solution Approach 1:
The fixture employs adjustable threaded rods that can be extended or retracted to achieve optimal thread engagement length for different motor positions and power levels. This dynamic adjustment capability ensures sufficient thread engagement for high-force applications while maintaining ease of position adjustment. The threaded rods can be selected or adjusted based on the specific force requirements of the application.
3Power
If high-power motors are mounted using conventional fixtures, then power output is increased, but the likelihood of thread damage and mechanical wear increases, reducing system efficiency
Solution Approach 1:
The mounting plates and contact surfaces incorporate curved or rounded features that distribute mechanical loads more evenly across the thread engagement area. This reduces stress concentration points that would otherwise lead to thread damage under high-power conditions. The curved surfaces also facilitate smoother force transmission and reduced mechanical wear.

Function Achieved in This Case
The solution provides improved pulling power and affordability, allowing for precise motor positioning without damaging the assembly, thus reducing mechanical wear and maintaining system efficiency.
Implementation Method 1
At least one of the first aperture, the second aperture, or the bore includes screw threads that threadably engage the adjusting rod such that the motor fastener moves along the elongate slot when the adjusting rod is rotated.

AI summary
A motor mounting assembly for mounting a motor includes a motor base and a motor mounting fixture. The motor base has an elongate slot and a threaded adjusting rod. The motor mounting fixture cooperates with the slot for securing the motor to the base and includes a fixture body and a coupling member. The fixture body includes a fixture base and first and second oppositely disposed legs. First and second apertures extend through the first and second legs and a motor fastener projects proximally from the fixture base to be received in the slot. The coupling member has a through bore aligned with the first and second apertures between the first and second legs. At least one of the first aperture, the second aperture, or the bore includes screw threads engaging the adjusting rod for adjusting a position of the motor.
