Propulsion TRIZ Cases
- Guide Shoe Profile for Longwall Rack Engagement Under Wear
Angled and curved guide shoe surfaces keep the mining machine engaged with the rack as wear develops, reducing misalignment and extending service life.
- Rackbar Extension Rib Fit for Mining Machine Rotation Control
A ribbed rackbar extension tightens third-axis tolerance while preserving needed motion, reducing sprocket misalignment, lateral movement, and wear.
- Mining Machine Guide Shoe with Curved Surfaces for Rack Engagement
Angled and curved guide shoe surfaces preserve mining machine rack engagement, improving control and extending component life.
- Replaceable Wear Inserts for Shearer Loader Guide Shoes
Segmented wear inserts on shearer loader guide shoes allow independent replacement of worn surfaces without removing the entire assembly.
- Longwall Shearer Control via Inertial Feedback
Inertial feedback loops adjust cutting drum positions to maintain profile accuracy despite floor irregularities, reducing operator intervention.
- Adjustable Guide Shoe for Mining Machine Sprocket Engagement
An adjustable guide shoe repositions a drive sprocket via a movable support to maintain engagement quality and reduce wear on mining machine racks.
- V-Shape Clamping Arms for Cable Puller Conduit Attachment
Radially nesting gripping members on pivotable arms distribute load across conduit diameters, eliminating multiple adaptors and reducing setup time.
- Mining Chain Guide Pressure Roller Wear Reduction
Rotating pressure roller converts sliding friction into rolling motion, extending service life of mining machine chain guides.
- Shearer Mainframe Bearing Unit for Component Handling
Integrated mainframe bearing units support heavy shearer components, enabling safe handling in low-clearance underground mining environments.
- Plow Guide Assembly Service Clearance for Maintenance
Segmented plow guide assembly allows bottom guide member replacement through one service clearance, reducing maintenance downtime.
