The gear reduction assembly also includes a first internal gear engaged with the first spur gear, a second internal gear engaged with the second spur gear, and a hub associated with the first internal gear.

A gear transmission comprises an internal gear, and an external gear that meshes with the internal gear and rotates eccentrically relative thereto.

A gear profile for orbital gear transmission is disclosed in which an outer gear (10) and an inner gear (30) are included.

A gear transmission is provided with an internal gear, and an external gear which makes eccentric rotation relative to the internal gear while engaging with the internal gear.

An internal gear is formed at the inner periphery of the case.

The annulus (16) is directly driven from an input gear (25).

An inner gear (30) driven by a rotary shaft (20) and an outer gear (40) are accommodated in a housing (10).

An internal gear of the receiving device has a large transmission ratio.

The first internal gear has a first number of teeth, the second internal gear has a second number of teeth, and the first and second numbers of teeth differ by from one to five teeth.

Provided is an internal gear pump having an excellent seize resistance.

The speed-reducing mechanism (17) has an internal gear (39) engaged and rotated with the output shaft (16) and an external gear (40) with which the internal gear (39) internally meshes.

The turntable is provided with an internal gear (6) cooperating with the planetary gear.

The invention relates to an internal gear pump (14) which comprises an inner rotor (100) which can be driven to rotate about a driving axis (104).

The invention relates to an internal gear pump (1) for a hydraulic vehicle brake system.

The inner gearing (6) drives the flywheel (1) using a shaft (4) and a gear (5).
