A laterally movable coupling disconnects shafts for easier inspection and service while maintaining torque transfer and reducing wear.

An aluminum drum intermeshes with a steel gear assembly to cut transmission weight and cost while preserving rigidity and wear resistance.

Radially offset apertures and a guidance plate enable precise centrifugal mass movement for reliable clutch engagement without added parts.

A modular male-female coupling with shaft keyway and teeth reduces wear and simplifies replacement in railway welding machine drives.

A resilient shift lever stores elastic energy to keep an axle disconnect operating through torque and misalignment blocked modes.

A movable active gear shares one motor between scanning travel and paper feeding, cutting cost while keeping both mechanisms operating reliably.

A clutch-driven spindle lets a furniture or appliance door switch between motorized torque transmission and easy manual movement with fewer parts.

A top-land to bottom-land gear contact lets an internal-gear one-way clutch shrink in diameter without losing transmission torque or adding axial size.

A preloaded leaf spring and bellcrank coupling removes cable actuation, prevents backlash, and simplifies reconnection on solid shafts.

A rotation-actuated clutch shifts axially to couple or decouple a threaded spindle, enabling one-motor door movement and easy manual operation.

Rotating an axial cam moves a slidable driving ring to engage toy gearbox gears, avoiding complex stickshift parts and improving layout versatility.

Rotational-position-based disconnect timing separates the generator input member within a target angle range to cut wear, debris, and maintenance.

Relative rotational movement drives a cam and stop arm to shift the clutch plate into positive engagement without separate actuation.

Electromagnetic solenoids replace slow hydraulic actuation in a two-way clutch, enabling fast directional locking with low neutral drag.

Swirl breaks disrupt entrapped lubricant rotation inside a clutch, reducing vibration, rotor-dynamic instability, and wear.

A three-position shifting clutch lets powered furniture switch to manual movement during drive failure while supporting secure engagement and overload release.

A three-part tapered tooth pulling side cuts dog clutch actuation force, while maintaining torque transfer and reducing noise, vibration, and wear.

A friction-induced actuator shifts the switching element without spring-loaded pawls, cutting freewheeling noise, wear, and axial space.

Helical gear axial force retracts engaging portions to release drive transmission, preventing gear deformation under excessive load.

Rearward spring biasing traps the pawl on the inner race, resolving assembly stability issues without increasing packaging size.

Rollers and pins on a rotary table enable self-aligning power transfer between shafts, eliminating the need for precise concentricity adjustments.

Rotating the shift cam creates local minimum spring forces to secure positions and prevent automatic switching in compact clutch designs.

A transmission clutch uses a rotating shifting cam to move a switching element between positions against spring force.

A wheel spindle drive element displaces material to create a high torque transmission joint with the spindle.

Segmented bearing housing and clutch modules resolve durability versus repairability trade-offs by allowing independent service without specialized tools.

Rotating a cage shifts pawl engagement from one-way to fully locked mode, resolving adaptability versus complexity trade-offs.

Segmented sliding sleeves reduce manufacturing complexity while maintaining robust engagement for transmission shifting.

Bottom bracket motor merges stator housing with frame to eliminate complex cable routing while claw coupling transmits torque without play.

A horizontal-pull clutch uses a flexible rubber seal to isolate the operating shaft from external contaminants while maintaining smooth mechanical engagement.

Spring applies axial force to lock second clutch dog, preventing disengagement under rotary load and ensuring reliable power transfer.

Distributed point actuations engage the sliding wheel directly, eliminating collar wear and reducing maintenance costs in hoisting machines.

Identical limiting and engagement tooth profiles increase load-bearing capacity while reducing flexural rigidity in transmission synchronizers.

A ramp unit converts rotational drive into axial movement using rollers that roll against inclined surfaces.

Co-rotating elements synchronize rotation in a clutch weight assembly, allowing push elements to compress weights for stable engagement.
