A bearing chamber housing () for bearing a shaft () of a turbomachine (), including a housing outer shell () that delimits an oil chamber () of the bearing chamber housing () radially outwardly in relation to a rotational axis () of the shaft (), and a housing inner shell () for bearing the shaft (). The housing inner shell () is radially connected to the housing outer shell () via support ribs () that in each case extend axially, at least in part, and the housing inner shell (), the housing outer shell (), and two support ribs () that are next-adjacent to one another jointly delimit a cavity () that is axially open at the rear, and thus lead into a rear opening (). The rear opening (), viewed in tangential sections, has a clearance () in each case that constitutes at least 50% of a circumferential distance () between the next-adjacent support ribs ().

Bearing chamber housing for a turbomachine

The present invention relates to a housing arrangement for a turbomachine, comprising a support element, which is configured to bear a shaft, and a housing, which is centered at the support element. The housing is composed of an inner housing and an outer housing fastened at the support element, the housings being connected to each other by at least one connecting strut. A press fit is provided between the support element and the inner housing, in order to center the inner housing at the support element.

Housing arrangement for a turbomachine as well as turbomachine arrangement having such a housing arrangement and method for manufacturing the housing arrangement

A bearing chamber housing for supporting a shaft of a turbomachine is provided, the bearing chamber housing including an additively built-up housing wall which bounds an oil chamber of the bearing chamber housing radially outwardly relative to an axis of rotation of the shaft, the housing wall being built up with an oil duct which has an inlet opening toward the oil chamber for admission of oil from the oil chamber into the oil duct, and which has an outlet opening for discharging the oil from the oil duct, the outlet opening being located at a different axial position and at a different circumferential position than the inlet opening, considered relative to the axis of rotation of the shaft, and the oil duct having an extent with both an axial component and a circumferential component, at least over a portion thereof.

The present invention relates to a bearing chamber housing for bearing a shaft of a turbomachine, comprising an additively built-up housing section and a cover, which, in each case referred to an axis of rotation of the shaft, connects axially to the housing section and has a radially extending collar, which collar axially bounds an oil space of the bearing chamber housing, wherein the cover is assembled with the housing section and is connected therewith via a weld.

The present invention relates to a bearing chamber housing for bearing a shaft of a turbomachine, having an additively built-up housing wall and a cover of the oil chamber, wherein, in each case referred to an axis of rotation of the shaft, the housing wall bounds radially outwardly an oil chamber of the bearing chamber housing and the cover of the oil chamber disposed on an axial end of the housing wall axially bounds a region of the oil chamber; the region bounds radially inwardly an inner shell of the bearing chamber housing.

A wear adjustor is provided for adjusting the wear of brake pads and a brake disc of a pneumatic disc brake having a brake application device actuated by a rotary lever. The wear adjustor is preferably inserted into an adjusting spindle of the brake application device. An axial bearing is formed axially on a side of a drive ring, and a ball ramp coupling with a freewheel function is formed axially on the opposite side of the drive ring. The ball ramp coupling has balls and a drive socket which is arranged axially, on the drive side, between the axial bearing and the balls thereof, a cone clutch being arranged between the clutch ring on the output side and an elastic sleeve for a cylinder spring. The cone clutch has the output-side clutch ring and a cone socket connected to the elastic sleeve, and clamping balls are arranged between the output-side clutch ring and the cone socket.

A wear adjustor adjusts the wear of brake pads and a brake disc of a pneumatic disc brake having a rotary lever brake application device. The wear adjustor is insertable into an adjusting spindle and attached to a caliper of the disc brake by a bearing disc. An axial bearing is formed axially on a side of a drive ring, and a ball ramp coupling with a freewheel function is formed axially on the opposite side of the drive ring. The ball ramp coupling includes balls and a drive socket which is arranged axially, on the drive side, between the axial bearing and the balls thereof, a cone coupling being arranged between the coupling ring on the output side and an elastic sleeve for a cylinder spring. The output-side coupling ring is designed for a working rotational angle defined by at least one fixed abutment.

A method is provided for fixing an adjustment device on a disc brake, particularly a pneumatically actuated disc brake. The adjustment device is inserted in a previously adjusted idle position into an adjusting spindle of the disc brake, wherein a coupling of a shift fork of the adjustment device is carried out with a rotating lever of the disc brake, and a centering is carried out by a bearing disc of the adjustment device in a receptacle of a brake caliper. The adjustment device is positioned by twisting the same. The adjustment device is secured on the disc brake by locking the bearing disc on the brake caliper by a locking element.

Method for fixing an adjustment device on a disc brake

A wear adjustor is provided for adjusting the wear of brake pads and the brake disc of a pneumatically operated disc brake having a brake application device that can be actuated via a rotary lever. The wear adjustor is able to be inserted into an adjusting spindle of the brake application device. The wear adjustor includes a clutch ring for coupling to a spring sleeve that is in engagement with the adjusting spindle. A blocking device is disposed between the adjusting spindle and the wear adjustor. The blocking device forms a stop for the adjusting spindle in the tangential direction relative to the rotating direction.

An optimized disc brake includes two fixed mountings and one free mounting, and an assembly space optimized brake carrier and corresponding brake lining for a reaction side of the disc brake are provided.

Disc brake with optimized caliper mounting and brake lining

The invention relates to an adjusting device of a disk brake, in particular a pneumatically actuatable disk brake. The adjusting device is in embodied in such a manner that it can rotate at least one rotatable spindle which acts upon at least one pressure piece on the brake lining and which comprises an output toothing arrangement. The output toothing arrangement comprises at least one tooth which engages in a groove of the rotatable spindle. The invention is characterized in that the output toothing arrangement and/or the groove are embodied in such a manner that they can be elastically compressed.
