A gear transmission for transmitting a drive between a pinion and a component driving the same or driven thereby. This latter component is of dimensions substantially larger than that of the pinion, and the pinion and its driven component have parallel axes. The teeth of the pinion have a width parallel to its axis substantially less than the width of the teeth of the other component parallel to the axis of the latter. The pinion is preferably made of steel and case-hardned, while the other component is provided with surface-hardened teeth, such as induction or flame-hardened teeth.
