Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grease sensor installation structures in bearing systems face issues with grease leakage, instability, and inconvenient installation, which affect signal detection accuracy and machine safety.
Innovation Solution
A resilient grommet-based installation structure for the grease sensor, where the grommet forms a tightly sealing interface with the sensor probe, using oil-resistant elastomeric materials like silicon rubber or fluoro rubber, and featuring sealing projections and limiting surfaces for secure and leak-proof contact within the bearing housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If threaded fasters are used to fasten the grease sensor probe onto the housing, then the sensor can be securely attached, but grease leakage occurs and the installation becomes inconvenient
Solution Approach 1:
A resilient grommet is introduced as an intermediary component between the probe and the housing. The grommet includes a resilient portion that contacts the probe and a sealing portion that prevents grease leakage. This mediator solves the contradiction by providing both secure attachment and leak prevention without requiring threaded fasters.
Solution Approach 2:
The resilient grommet is made of flexible material that can deform to accommodate the probe while maintaining a tight seal. The flexible nature of the grommet allows it to conform to the probe surface and create an effective sealing interface, preventing grease leakage while securing the probe in place.
2Reliability
If threaded fasters are used to install the grease sensor, then the sensor can be fixed, but the installation process becomes complex and inconvenient
Solution Approach 1:
The resilient grommet serves as a pre-assembled intermediary component that simplifies installation. Instead of requiring separate threaded fasteners and sealing elements, the grommet integrates both functions into a single piece that can be installed by simple insertion, making the process convenient while ensuring reliable fixation.
Solution Approach 2:
The sealing function and fixation function are merged into a single resilient grommet component. This integration eliminates the need for multiple separate parts and assembly steps, thereby simplifying the installation process while maintaining both leak prevention and secure attachment.
3Ease of operation
If the probe is inserted directly into the housing without a sealing mechanism, then installation is simple, but grease leakage occurs
Solution Approach 1:
The resilient grommet is inserted into the housing as a mediator between the probe and the housing wall. It provides a sealing interface that prevents grease leakage while maintaining the simple insertion-style installation. The grommet's resilient portion accommodates the probe without requiring complex fastening mechanisms.
4Object-generated harmful factors
If a resilient grommet is used to seal the probe, then grease leakage is prevented, but the installation complexity increases
Solution Approach 1:
The sealing function and structural support function are merged into a single resilient grommet component. This integration prevents grease leakage while avoiding the need for additional separate parts, thereby not increasing overall device complexity despite adding the sealing capability.

AI summary
An installation structure for grease sensor includes a housing having a through-hole. A resilient grommet is installed in the through-hole. The resilient grommet has an installation hole. A probe of the grease sensor extends from a base and is inserted into said installation hole such that the end of the probe extends into the interior of the housing to contact the grease. The inner surface of the resilient grommet is resiliently pressed against the outer surface of the probe to form a tightly sealing interface. This kind of installation structure allows effective grease sealing, and convenient and stable installation.
