Multi-Axis Motor Mount for HVAC Belt Alignment and Tension Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional HVAC systems face difficulties in acutely adjusting the position of the motor relative to the blower, making it challenging to effectively install and maintain the belt for transferring rotational motion, which affects the efficient operation of the blower.
Innovation Solution
An adjustable motor mount system is introduced, featuring a first bracket that moves along a mounting rail and a second bracket that adjusts transversely to the first bracket, allowing the motor to be positioned accurately relative to the blower in multiple directions for installation, maintenance, and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed motor mount is used, then the structure is simple and stable, but the motor position cannot be adjusted relative to the blower
Solution Approach 1:
The motor mount is divided into multiple independent brackets (first mounting bracket, second mounting bracket, third mounting bracket) that can adjust along different axes. Each bracket segment provides adjustment freedom while maintaining structural simplicity through modular design.
Solution Approach 2:
The mounting brackets are designed to be dynamically adjustable along specified axes rather than fixed. The first bracket adjusts along a first axis, the second bracket adjusts along a second axis transverse to the first, enabling the motor to reach optimal positions relative to the blower.
2Ease of operation
If the motor position is fixed, then the installation is simple, but the belt alignment and tension adjustment is difficult
Solution Approach 1:
The adjustable mounting brackets allow the motor to be positioned dynamically during installation and maintenance. The first bracket provides adjustment along one axis while the second bracket provides adjustment along a transverse axis, enabling precise belt alignment and tension adjustment.
Solution Approach 2:
The system allows changing the positional parameters of the motor relative to the blower by adjusting the brackets along different axes. This enables optimization of belt alignment and tension parameters during installation and maintenance operations.
3Measurement precision
If multiple adjustment axes are provided, then the motor can be precisely positioned, but the mounting structure becomes more complex
Solution Approach 1:
The positioning system is segmented into multiple independent brackets, each responsible for adjustment along a specific axis. The first mounting bracket adjusts along the first axis, the second mounting bracket adjusts along the second axis, providing precise positioning without requiring a single complex multi-degree-of-freedom mechanism.
Solution Approach 2:
Positioning precision is achieved by adding dimensional independence - the first bracket provides adjustment in one dimension (first axis) while the second bracket provides adjustment in a perpendicular dimension (second axis transverse to the first). This orthogonal arrangement achieves 2D positioning precision through simpler 1D adjustment mechanisms.

AI summary
A heating ventilation, and/or air conditioning (HVAC) system includes a support structure having a mounting rail, a first mounting bracket coupled to the mounting rail and configured to be adjustably positioned along a first axis of the mounting rail, and a second mounting bracket directly coupled to the first mounting bracket. The second mounting bracket is configured to support a fan motor mounted thereto, the second mounting bracket is configured to be adjustably positioned along a second axis of the first mounting bracket, and the second axis of the first mounting bracket is transverse to the first axis of the mounting rail.
