A gearbox for a planetary gear having a hollow-cylindrical housing body having a first internal gear, and a bearing flange engaging at least in sections coaxially in the housing body, so that an overlap area is formed, wherein the housing body and the bearing flange are firmly bonded to each other in the overlap area by laser irradiation welding. The bearing flange has a second internal gear in the overlap area. The gearbox relates to a planetary gear and a motor/transmission combination having such a gearbox and a production method thereof.

Gearbox for a planetary gear

A method for producing a ring gear for a planetary gear train, wherein a continuous profile is produced by an extrusion process and the continuous profile is subsequently cut to a predetermined cutting length in order to form a ring gear body.

A housing for a motor-transmission unit with at least two housing sections which have in each case at least one accommodation segment for receiving a motor and an internally-toothed, internal ring gear segment for receiving a gear of a planetary gear unit, wherein the housing sections can be or are connected with each other and wherein, in the assembled state, the accommodation segments of the housing sections together form at least one accommodation compartment for holding the motor, and the internal ring gear segments of the housing sections together form an internal ring gear for mating with a gear on the planetary gear unit.

Housing for a motor-transmission unit and method of making the housing

A gear housing for an epicyclic gear set, the gear housing including a hollow wheel having internal teething and a first front end with a first front-side joining surface; a housing cover having a second front end with a second front-side joining surface for longitudinally axially covering the hollow wheel; and a bonded connection for connecting the first front end to the second front end through the mating of the first and second front-side joining surfaces, at which the hollow wheel and the housing cover are connected to each other by a bonded connection, in particular, by heated tool welding, infrared welding, ultrasonic welding, or rotary friction welding.

A magnet assembly in an electric drive having a shaft. The assembly includes a permanent magnet bonded in plastic and having two protrusions. An adapter has two protrusions and two recesses. The end face of the shaft has two cavities, which receive the two adapter protrusions to mount the adapter to the shaft. The two protrusions of the magnet are received in the recesses in the adapter in order to mount the magnet to the adapter. In another embodiment the shaft has an outer circumferential surface. Here, the adapter has a recess of a first shape and a second recess for mounting the adapter onto the outer circumferential surface of the shaft and the permanent magnet has a protrusion shaped to mate with the first shape of the first recess in the adapter, and the first recess is configured to receive the protrusion to mount the magnet to the adapter.

An electronically commutated DC motor has a stator wound with a multi-phase stator winding, a permanent magnet rotor mounted rotatably about a motor axis, a circuit board, a guide plate electrically connected to the winding and a housing component. In one implementation, a DC motor can easily be manufactured with the fewest possible process steps, which exhibits a short axial length and a low weight as well as good heat-dissipation properties. It is also an object of the invention to create a DC motor with integrated electronics, whose motor interior can be filled with oil, and which holds the electronics sealed against this oil. For reasons of logistics, an attempt is also made for partial components, such as the electronics, to be designed such that they are capable of complete prior assembly and testing.
