Gearboxes TRIZ Cases

Tubular protrusions fitted into matching holes correct resin housing warpage, stabilizing gear meshing and reducing vibration and noise.

A wheel-coupled dynamo harvests rotational speed differences to power sensors continuously without battery interference.

A mounting bearing lets the generator rotor rotate and shift axially on the gearbox shaft, simplifying decoupling and maintenance access.

External shift and clutch linkages free crankcase space, enabling compact straddled vehicles that support different gear-shifting types.

A hollow-shaft axial-flux motor and coaxial driveshaft layout improve power transfer while easing thermal loads in a compact EV drivetrain.

A wheel-integrated worm drive cuts golf trolley bulk while adding deceleration, self-locking, and safer movement on uneven terrain.

A housing flow path overlapping the ring gear improves coolant heat transfer in motor units with planetary reduction gears.

Identical left and right gear trains cut gear variation, lower manufacturing cost, and improve whole-vehicle noise and vibration behavior.

Hermetic inert gas sealing cuts oxidative wear in electrified moving components, extending lubricant life without harmful anti-wear additives.

A carrier-mounted dual-case reducer transmits torque to multiple members while cutting protrusion, preserving bucket space, and protecting motors.

An elastic retaining element constrains the stop bushing to cut play, vibration, and noise while improving pushrod neutral-position accuracy.

Split upper and lower oil reservoirs maintain lubrication in a low-profile transmission while reducing agitation loss across speed changes.

Separating radial and axial load support cuts shaft bending stress and misalignment while keeping transmission gearwheels compact and high-speed capable.

A preassembled eAxle cover integrates the oil pump, filter, and passages to save housing space and simplify final assembly.

A banjo axle housing integrates the motor and differential to simplify machining, cut parts, and improve space use.

Offset boss portions disperse collision stress in a transaxle case, suppressing cracks while preserving package space.

By moving the clutch drive unit onto the crankcase cover, this case cuts power-unit length while protecting and concealing the harness.

Cross-plane torque transfer cuts gearbox width, bearing count, weight, and cost while preserving high torque handling in twin-motor drivetrains.

A removable adaptor repositions the idler gear so off-road portal hubs can change gear ratios faster with less disassembly.

A variable-axis sun and ring gear layout keeps wheel drive continuous while moving the motor off-wheel to cut shocks, unsprung mass, and ride harshness.

A prefixed gear cover locked by the motor support keeps a vehicle seat gear assembly stable under load without screws or welding.

Two aligned reduction units share motor input and load to raise reducer rigidity and strength without increasing construction machine size.

A laterally offset electric machine and pseudo dual-layshaft layout free axle space and avoid frame interference during suspension travel.

An annular bracket protrusion aligns the bearing, shaft, and housing in a compact table drive while reducing deformation and extra parts.

A permeable screen and magnets partition the axle housing and spindle assembly, blocking debris while preserving lubricant flow and cooling.

Feedthrough fasteners isolate trumpet arms from axle housing walls, reducing deflection stress, seal leaks, and bearing misalignment.
