A gear face at a lower end of the tube gear interacts with a corresponding gear face on the housing.

The first face gear (50) directly drives a rotor, but the second face gear (45) does not directly drive a rotor.

A concentric face gear assembly includes a first face gear (50) having first face gear teeth and second face gear (45) having second face gear teeth.

The drive gear and the at least one driven gear do not include a taper gear or a face gear.

Wheel that receives energy from the center wheel and drives the escape wheel.

The shaper (18) is then removed, and the face gear (112) is case hardened.

A face gear (220) has at least the locking jaws (230) disposed in a slot (225) provided on the face of the face gear oriented away from the housing (310).

The gear train (10) includes at least one side gear (12) comprising a helical face gear and a plurality of helical pinions (14) in meshing engagement with the helical face gear.

The shaft is rotatably connected to a power transmission mechanism which includes a face gear coupled to a spur gear.

The invention relates to a tooth coupling, in which the toothing is a face gear toothing.

A gear train (10) is provided that includes at least one side gear (12) comprising a helical face gear and a plurality of helical pinions (14) in meshing engagement with the helical face gear.

The mechanism also comprises a bearing (240) between the housing (310) and the face gear (220).

The adapter gear is a low angle face gear (20) that includes a drum (24) having an inner cylindrical wall adapted to be mounted on a shaft, and a drum face connected to the inner cylindrical wall.

The mechanism also comprises at least one compression spring (250) disposed in a corresponding groove (222) on the face gear (220).

A shaper (18) is first placed in contact with a face gear (112), to thereby shape a surface of the face gear (112) into a plurality of face gear teeth (114).
