Crankshafts TRIZ Cases
- Bearing Member Swaying Groove Design for Photosensitive Drum
Spherical coupling and segmented grooves enable smooth attachment without forceful insertion, resolving assembly precision issues.
- Crankshaft Ribs and Recesses for Rigidity
Crank arms with pin-facing recesses and side ribs increase flexural rigidity while reducing weight.
- Drivetrain Fill-Plug Integrating Sealing and Mounting Load Distribution
A fill-plug design integrates fluid sealing with structural mounting to secure drivetrain housings.
- Crankshaft Gear Positioning for Engine Weight Reduction
A crankshaft gear positioned on the outer periphery of a crank web reduces engine weight while securing high reliability.
- Fluid Container Catchment Surface and Inlet Positioning
Elevating the inlet above the fluid level prevents spilling when transitioning from prone filling to upright carrying.
- Sleeve Bearing Lubrication for Railway Traction Motors
Multiple wicks and oil flinger grooves distribute lubricant to reduce unit loading on the journal.
- Locomotive Lubricant Management via Quality-Based Oil Replacement
Analyzing test portions of engine oil determines exact replacement quantities, eliminating unnecessary full changes and reducing lubricant waste.
- Eccentric Boring Bar with Segmented Guide Elements
Segmented guide elements enable eccentric retraction of a boring bar, preventing surface damage while maintaining concentricity.
- Nitrocarburized Crankshaft Steel Straightening
Normalizing treatment at 780 to 850 C creates a ferrite plus pearlite microstructure in nitrocarburized crankshaft steel.
- Hose Cap Coupler With Secure Clip For Engine Fluid Drainage
A hose cap coupler with a secure clip mounts to engine housings for tool-less fluid drainage.
- Fan Motor Bushing Hollow Wall Heat Dissipation
Segmented bushing walls with a hollow core isolate thermal energy from motor components, preventing abnormal operation caused by heat conduction.
