Gearboxes TRIZ Cases

A Hybrid Orbitless gearbox combines an Orbitless first stage with a Coupled Orbitless second stage to deliver high speed ratios in compact volumes.

Flow forming produces differential casing halves with locating surfaces that align central axes, eliminating casting alignment errors.

A coaxial output motor integrates transmission and gear shift mechanisms within a hollow rotor shaft to achieve a compact drive assembly.

A pulley assembly uses segmented wall sections between base and support plates to distribute rotational loads across multiple angular positions.

Strain gauges measure transfer case housing deformation to calculate output torque, resolving interference from rotating shaft measurements.

Rounded corner relieves stress concentration, enabling compact differential device size while maintaining structural integrity.

A gear case design featuring a dedicated mounting arm extends outward from the first receptacle to secure actuator components without interference.

A fixing member bolts a cylindrical housing to a lower case, preventing sun gear rotation and eliminating circumferential backlash.

A spur gear housing uses ribbed side walls to transfer tooth engagement loads directly into the foundation, isolating internal stages from external forces.

Integrating a sensor unit on the gear unit housing cover resolves the contradiction between limited functionality and low manufacturing complexity.

An integrated cooling circuit circulates lube oil through an oil cooler to prevent overheating and seizure of the reduction gear unit.
