Driving Apparatus TRIZ Cases

A single ball on an inclined bearing surface creates axial spindle oscillation, enabling high-speed drilling with shorter chips and lower wear.

Three-deck support and slit clamping keep the mandrel assembly aligned during adjustment, improving machining precision and transmission.

A motor-driven pulley layout fastens or loosens bolts at different radii at once, cutting maintenance time while keeping pressure uniform.

Real-time pulley position detection aligns clutch serrations in a machine tool drawbar drive, reducing vibration and processing defects.

Encoder pulley feedback aligns clutch serrations during spindle-to-clamp switching, preventing vibration, noise, and machining defects.

Pre-positioned actuator members engage rotating jaws at each station, cutting passive transfer time and raising machine tool throughput.

A copper bush, electric brushes, and insulation let existing machine tools switch quickly into EDM, cutting upgrade cost and setup time.

Motor-driven spindle rotation enables precise CNC stroke positioning in gear shaping without manual adjustment or a separate shaping head slide.

A crank-driven support body converts rotary motion into linear tool travel to cut forming downtime, raise output, and reduce vice stress.

Spindle force feedback lets angle-head friction stir welding reach tight positions while adjusting speed and load to protect the tool and spindle.
