Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The motor-incorporating roller with a grease containing portion integrated into the interlocking gear faces challenges in manufacturing due to high costs and time requirements for bonding, and the grease supply method is cumbersome, leading to potential separation issues during long-term use.
Innovation Solution
A motor-incorporating roller design where the grease supply portion is integrated with the power output member through a shaft portion, restricting axial movement and allowing for separate grease replenishment, with features like protrusions for secure attachment and centrifugal grease distribution to prevent separation and maintain lubrication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the grease containing portion is integrated into the interlocking gear, then the lubrication can be maintained, but the manufacturing cost and time increase due to bonding requirements
Solution Approach 1:
The grease containing portion is integrated into the power output member as a single molded piece, eliminating the need for separate bonding processes. The power output member includes both the gear functionality and the grease containment structure, simplifying manufacturing while maintaining lubrication reliability.
2Stability of the object's composition
If the grease containing portion is bonded to the plate-like member, then the structure is stable, but the grease introduction becomes cumbersome
Solution Approach 1:
The grease containing portion is designed as a separate molded part that integrates the power output member and grease containment. This segmentation allows the grease introduction hole to be accessible during assembly while maintaining structural stability through precise molding and positioning features.
3Reliability
If the grease containing portion is fixed to the plate-like member, then separation is prevented, but the grease supply mechanism becomes complex
Solution Approach 1:
The power output member integrates both the gear transmission function and the grease containment function into a single component. This merging eliminates the need for separate fixing mechanisms between the grease containing portion and the support structure, preventing separation while simplifying the overall device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures reliable grease supply to the gears, preventing frictional resistance increase and maintaining high power transmission efficiency while simplifying grease introduction and preventing separation of the grease supply portion during operation.
Implementation Method 1
the grease supply portion is integrated with the power output member through the shaft portion to restrict movement of the shaft portion in an axial direction
Implementation Method 2
since the grease can be supplied between the members in the reducer in conjunction with the rotation of a motor body on its axis, the lubrication can be maintained
