Compressor Mounting Feet Design for Rail Stability During Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Refrigeration compressors, particularly reciprocating piston compressors, tend to partially fall between mounting rails during installation and removal due to instability, which can lead to misalignment and increased vibration.
Innovation Solution
The compressor features bent sheet metal feet with complementary mounting features, including internally threaded holes, that allow for secure attachment to support rails in both longitudinal and transverse orientations, enhancing stability and preventing partial falling between rails.

Engineering Contradiction Analysis
1Reliability
If the compressor is mounted on parallel mounting rails, then the compressor can be securely supported, but the compressor tends to partially fall between rails during installation and removal due to instability
Solution Approach 1:
The mounting system is divided into separate components: the compressor case with integrated feet and the parallel mounting rails. The feet act as intermediate elements that connect the compressor to the rails, allowing for easier installation and removal while maintaining stability during operation.
Solution Approach 2:
The feet serve as intermediary elements between the compressor case and the mounting rails. These feet provide a stable connection interface that prevents the compressor from partially falling between the rails during installation and removal, while still allowing for secure mounting when installed.
2Stability of the object's composition
If the compressor is securely mounted to prevent partial falling, then stability is improved, but vibration and misalignment may increase due to rigid mounting
Solution Approach 1:
The feet are designed with specific geometric parameters including slots and apertures that allow for adjustment and accommodation of vibration. The slot dimensions and aperture sizes are optimized to provide stable mounting while accommodating vibrational movements, thus reducing the transmission of harmful vibrations.
Solution Approach 2:
The mounting feet incorporate dynamic elements such as slots that can accommodate movement and adjustment. This allows the mounting system to adapt to vibrational forces during operation, maintaining stability while reducing the harmful effects of vibration and misalignment.
