The invention relates to a rotor block () comprising a housing () with at least one connection surface (A) that absorbs the load and pivot bearing seats () for plain and/or anti-friction bearings () that are designed to support a rotor (). To dismount the rotor () from the housing (), the plain and/or anti-friction bearings () can be dismantled from the exterior and the rotor () from a side () lying transversally to the bearings. The pivot bearing seats () take the form of recesses () that are directly configured in the housing wall, without the use of annular bodies. To facilitate the mounting and dismounting processes and to improve the precision of the rotor alignment, the pivot bearing seats () are configured in such a way that they form a segment greater than a semi-circle around the plain and/or anti-friction bearings (), leaving a section open on one side () in relation to said bearings (), thus forming a narrowing ().

Rotor block

A torque support, especially for wheel blocks, is arranged between a gear unit housing with a drive shaft and a driven unit housing. The torque support includes a plate-shaped base body which is detachably fastened to the gear unit housing with fastening elements. The plate-shaped base plate has at least two fastening locations comprising through openings for fastening the torque support to the driven unit housing. To keep the shearing forces resulting from the torque support and acting on the gear shaft small while the torsional moment is simultaneously absorbed with low play and in such a way that load peaks are damped, a corresponding plastic ring body is inserted into each through-opening in a positive-locking engagement. A side of the plastic ring body facing the driven unit housing has an edge area which widens radially outward forms an elastic disk element arranged between the driven unit housing and the torque support.

Torque support

A torque support mountable between a first housing of a driven unit and a second housing of a driving unit includes a scalloped one-piece plastic base body having a first side connectable with the first housing and a second side connectable with the second housing so as to be fixed with respect to rotation relative to both the first housing an the second housing. The first side includes a first planar contact face with through-openings for fastening with the first housing and the second side includes a flange-like edge area with a second planar contact face for resting against the second housing. The plastic piece is injection molded with support webs and includes metal bushings which are arranged perpendicular to the second planar contact face to provide a torque support which is simple and economical to manufacture, mechanically stable, has a certain elasticity and is adaptable to virtually any gear unit connection surfaces. The bushings may be pressed toward the second housing with fastening means while the second planar contact face presses against the second housing in a frictional engagement. Through-openings are formed at the flange-like edge area of the plastic base body for connection of the torque support to the first housing.

A securing ring, includes a body defining a ring opening and having a circumference of substantially circular configuration at formation of a slotted gap to define confronting ring ends. The body defines a ring plane and an axis of symmetry and has a radial width which continuously increases, at least in sections, from the ring ends onwards at both sides of the axis of symmetry. Each of the ring ends has a L-shaped configuration and is extended by a lug jutting out from the ring plane and formed with a throughbore. Both lugs of the ring ends are positioned on a same side of the ring plane, with the throughbores of the lugs extending in parallel relationship to one another and to the ring plane.

A running wheel block, including a housing having at least one connecting surface for connection to a supporting structure, an inwardly directed rotary bearing holding hub arranged in the housing, a rotary bearing mounted on the hub, and a running wheel mounted in the rotary bearing so that a section of its running surface projects from the housing toward at least one side. The housing is open on a side opposite to the holding hub. The running wheel encompasses the holding hub and is insertable onto or into the rotary bearing from the open side.

The invention is directed to a running wheel for traveling units which are movable on rails, especially for traveling cranes. The running wheel includes an outer running ring, a resilient damping hub inserted in central opening of the running ring. The hub transmits torque received from a drive shaft to the running ring. The resilient damping hub effectively intercepts occurring torque peaks forward of the gear unit and drive shaft, by elastically deforming while maintaining a connection at the central opening of the running ring without play.

A running wheel block, including a housing having at least one connecting surface for connection to a supporting framework, and further having two opposing, detachable side walls, two inwardly directed rotary bearing holding hubs, arranged in the housing, rotary bearings mounted in the hubs, and a running wheel mounted in the rotary bearings so that a section of its running surface projects from the housing toward at least one side. Each of the holding hubs is arranged on one of the two opposing side walls of the housing. The housing further includes at least one spacing holder arranged between the opposing side walls. The spacing holder forms a connecting surface. The detachable side wall has centering members that, when the side wall is attached to the housing, determine the position of the holding hubs relative to the running wheel axis.

The holding hubs include a first holding hub that is arranged on the cover. The cover has centering members for fixing a position of the holding hub relative to an axis of the running wheel when the cover is closed.
