Gearboxes TRIZ Cases

By placing radial and axial bearings directly at the shaft ends, this gearbox layout saves installation space and simplifies lubrication.

Snap-fastening holds transmission housing elements during adhesive curing, while sealing channels prevent seepage and cut assembly time.

Cantilevered flexured posts and roller races absorb planet gear loads, cutting gearbox weight, bearing complexity, and joint failure risk.

A split casing with a shorter input-side section cuts speed reducer weight while preserving secure vertical and horizontal mounting surfaces.

Offset planetary gearsets raise output torque in tight assembly spaces while keeping the torque multiplier compact, lighter, and efficient.

Interdigitated counter-rotating rotors and a geared output let one turbine efficiently support both 50 Hz and 60 Hz loads with less weight.

A shaft-driven fan and stepped axial cooling fins use a surrounding flange to guide airflow, improve heat dissipation, and cover tamper-prone areas.

A tuned mesh stiffness ratio lets an aircraft fan-drive epicyclic gearbox absorb small gear errors while limiting wear, deformation, and torsional vibration.

A sensor bar doubles as an oil channel, using gear-driven oil pickup to lubricate hard-to-reach transmission parts while cutting space and components.

A separate lubricant path outside the pin shafts cuts stress concentration in a wind turbine planet carrier and supports higher load capacity.

A partitioned breather chamber uses axial layout and staged air paths to restrict oil carryover and prevent atmospheric leakage in final speed reducers.

A nested worm wheel and intermediate rotary body enable compact, high-ratio transmission with lower wear and precision heavy-load performance.

A retractable screw-and-gear blind mechanism prevents packing cracks while enabling stable slat adjustment, engagement, and fixation.

A longitudinal groove in the intermediate bore lets the cutting tool reach the second bore in one setup, improving alignment and reducing machining time.

A detachable motorized knob drive helps endoscope users switch bending operations smoothly while reducing finger strain and securing attachment.

A unified pump-and-valve housing simplifies hydraulic machine installation by cutting external fluid connections, pressure loss, and assembly effort.

Curved fins on a two-part gearbox housing redirect axial airflow sideways to equalize cooling and maintain a planar sealed joint.

Integral restricting portions position the oil pipe accurately for gear meshing lubrication without enlarging the transmission case.
