The invention relates to a wheel system having a running wheel and a support body which at least partially surrounds the running wheel and in which the running wheel is mounted and from which the running wheel projects in order to come into contact with a rail. In order to allow predictive maintenance of the wheel system with a low inspection effort, it is proposed that a mechanical device for detecting and/or determining wear on the running wheel is mounted on the support body.

Wheel system, in particular for a crane

An arrangement with an end carriage, a plate, and a wheel block which is detachably fastened to the end carriage and comprises a housing and a wheel that is mounted in the housing and projects out of the housing, wherein the plate is located between the end carriage and the wheel block and is fixedly connected to the end carriage and has a base surface directed towards the housing, and wherein the housing has a groove which receives the plate and which has a bottom surface, directed towards the base surface, and side walls delimiting the groove, wherein the wheel block is aligned relative to the end carriage by means of an interlocking connection between the wheel block and the plate.

The invention relates to an arrangement comprising a travelling mechanism girder and a running wheel block fastened detachably thereto, wherein the running wheel block is comprised of a housing with at least one connection surface and a running wheel which is mounted in the housing and protrudes out of the housing. To facilitate the exchange of running wheel blocks, alignment of the running wheel block with respect to the travelling mechanism girder is secured through the use of a machined groove, in which a machined plate is held in a form-fitting manner, arranged on the connection surface of the running wheel block. After the running wheel block has been properly aligned, the plate is fixedly connected to the travelling mechanism girder, maintaining the alignment. The invention also relates to a method for the installation of an arrangement consisting of a travelling mechanism girder and a running wheel block.

Arrangement consisting of a travelling gear carrier and a running wheel block fastened detachably thereto, and installation method therefor

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 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.

Securing ring

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.
