摘要:
A molding material which contains a sinterable polymer and a wax as a binder and advantageously an ethylene/vinyl acetate copolymer, an organic peroxide, an azoester and an alcohol can be injection molded to give a molding, dewaxed without loss of dimensional stability of the molding and then sintered.
摘要:
An electric machine has at least two pairs of carbon brushes made up of one plus and one minus carbon brush, which interact with a commutator in order to supply current to the rotor, the carbon brushes being mounted with their brush holder on a brush plate via a mount, and the mounts on the brush plate lying across from each other at 180°. The holding part on at least one brush holder is offset from the center, in particular from the axis of symmetry of the brush holder, by an angle relative to the rotor axis so as to realize an asymmetrical placement of the carbon brush, the holding part on the other brush holders being disposed on their axes of symmetry.
摘要:
The invention relates to an electric motor comprising an electric conductor for supplying current, connected to a contact piece which is in contact with a component of the electric motor. Said conductor has, in a central section, a rectangular cross-section.
摘要:
A method for the production of press-hardened components, in particular a vehicle body component, from a semifinished product (2) made of unhardened, hot-workable steel sheet. A component blank (10) is formed from the semifinished product (2), pre-coated with a first coating (33), by a cold-forming method, in particular a drawing method. The component blank (10) is trimmed at the margins to a marginal contour (12′) approximately corresponding to the component (1) to be produced. The trimmed component blank (17) is heated and press-hardened in a hot-forming tool (23); then the press-hardened component blank (18) is covered with a second, anticorrosion coating (34) in a coating step.
摘要:
A multilayer brush, which essentially contains a composite having a graphite component and having a copper component, and a layered structure, a first layer being furnished with a high copper component and a further layer being furnished with a comparatively low copper component. It is provided that the copper component of the first layer in comparison with the copper component of the second layer corresponds to a ratio of ≦3/2.
摘要:
The invention is directed to methods and apparatus for repairing fractured, hollow-shafted hockey sticks. In one aspect, the invention comprises a shaft repair insert for joining together a broken hockey shaft so as to define a unitary, repaired hockey stick. In another aspect, the invention comprises a shaft repair sleeve for joining together a broken hockey shaft so as to define a unitary, repaired hockey stick. In another aspect, the invention is directed to a blade receiving insert capable of repairing a hockey shaft having a fracture proximate a blade receiving end. In another aspect, the invention is directed to a shaft extension member for repairing or adjusting the length of hockey shaft.
摘要:
The invention relates to a method for producing a carbon brush in a commutator for transmitting current in an electric motor, wherein the carbon brush is subjected to an artificial aging process after being produced and prior to being installed in the commutator, wherein the carbon brush is stored at an increased temperature for a defined period of time.
摘要:
A commutator for transmitting current in an electric machine is disclosed. The commutator includes an armature-side collector and at least one brush contacting the collector. At least one current-carrying component of the commutator is implemented as porous ceramic body having infiltrated metal.
