Friction Gearings TRIZ Cases

Curved toroidal disc contact surfaces keep roller contact points stable under bending, improving ratio and torque accuracy without larger discs.

An external hinge axis lets planet forks avoid interference while preserving drill-free rolling and a wider torque-speed ratio range.

A higher-curvature disc contact region prevents power roller contact shift under bending, preserving toroidal CVT ratio accuracy without larger discs.

Spiral cam discs replace circular profiles in a CVT to enable stepless ratio changes with non-slip power transfer and lower friction losses.

Axial bolt arrangement secures support columns in a toroidal continuously variable transmission to maintain structural integrity.

A low-profile rack and pinion gear drive system integrates stabilizer bearings directly into the rack structure to react separation forces.

A gear scheme for an infinitely variable transmission integrates a variator and planetary gearsets to provide multiple operating modes.

A modular linear actuator support module uses movable pulley blocks and a protective cover to carry the screw rod.

An intermediate gear element transfers motion between a toothed rack and a gear element, allowing the rack to remain housed within compact boundaries.

A coaxial drive apparatus uses a hollow spindle shaft to transmit rotation while the housing translates axially.

A cylindrical metal shaft container assembly with flexible rubber covers transmits rotational energy between distinct fluid compartments.

A toroidal continuously variable transmission transmits rotational force via friction between a carrier and disc.

Tilting shafts creates pockets that hold ball bearings, eliminating gear play to improve positioning accuracy.

Planetary variators with tractrix curves adjust ratios continuously, maintaining optimal engine speed and torque while eliminating energy loss during reversing.

Guide protrusions constrain holding device inclination to suppress centrifugal thrust and maintain power transmission efficiency at ultrahigh speeds.

Tapered bearings in planetary rollers eliminate gaps through push-in member compression, ensuring uniform rotation.

A convertible locking hook employs a Hall sensor to detect the driving wheel position, eliminating unnecessary stops during top displacement.

A differential drive assembly uses a conical rotor and rope circuit to enable efficient linear motion.

A deceleration mechanism employs transmission members wound around driving and driven wheels to achieve speed reduction without complex gear structures.
