Gear (mech.) is a system of specifically arranged mechanical elements that transmits rotational energy between shafts. The transmission link that receives motion from the engine-engine is called the lead, the link to which the motion is transmitted is called the slave.
Gear coupling is kind of mechanical couplers with a toothed engagement of connected shafts and rigid compensation of their axial, radial and angular displacements.
Gear coupling with countershaft is a gear coupling where one gear block and one sleeve are replaced by flange coupling half. And the shaft is pressed directly into the coupling half.
Gear motor is an electrical motor and reducer assembled as a single unit.
Gear ratio is the ratio of the greater angular velocity to the least one. The gear ratio number may not be less than one.
Gear ring is a component of gear couplings type MZ and MZP engaged with a hollow gear hub and made as a ring with inner gear row.
Gear train – transfer of the rotational energy through gear wheels that are made by cutting involute shape teeth out of the disc blanks.
