Technische woordenlijst

Mechanical play in the axial direction (along the shaft axis) of a bearing or guide.

Precision linear motion element with a ball-bearing spindle for high efficiency and zero backlash.

Defined mechanical play between tooth flanks or guide elements — intentionally allowed for temperature and tolerance compensation.

Ratio of output power to input power (η = P_out / P_in) — measure of the energy efficiency of a component.

Ratio of output power to input power specifically for gearboxes — affected by gear mesh losses, bearing friction, and lubrication.

Ratio of input speed to output speed (i = n₁/n₂) of a gearbox.

Gear tooth form with angled teeth for quieter operation and higher load capacity than spur gearing.

Standardized classification of enclosure protection against solid particles and liquids (IEC 60529).

Guidance system for linear motion — available in profiled rail, round shaft, or telescopic designs.

The linear distance a nut or screw advances per one full revolution — determines the ratio between rotational and linear motion.

The torque delivered at the output side of a gearbox — the product of input torque, gear ratio, and efficiency.

The speed of a motor or gearbox specified for rated operation, at which rated torque and power apply.

The maximum continuously transmissible torque of a drive or gearbox component under rated conditions.

Force acting perpendicular to the shaft axis on a bearing or guide.

Property of a gearbox in which a load on the output side cannot back-drive the gearbox — a load-holding system without a brake.

Rotational force that generates or transmits a turning motion. Unit: Nm.

Science of friction, wear, and lubrication — the basis for optimized lubricant selection and maintenance planning.

Condition with no measurable mechanical play in a drive or guide element — prerequisite for precise positioning.
