摘要： A feed system, rack bar and drive sprocket for moving an underground winning machine having a travel drive with drive sprocket having symmetrically profiled teeth, and rack bars with a plurality of rack teeth being arranged between a supporting strip and a guide strip of the rack bar. The tooth flanks of the teeth are inclined in the direction of movement and diverge towards the tooth tip for the interaction with tooth surfaces of teeth of drive sprocket. In order to improve the interaction between the teeth and produce less wear, the two tooth flanks of each rack tooth are concavely arched and form a trough between guide strip and supporting strip transversely to the direction of movement, with the trough rising towards the tooth tip, and the two tooth surfaces of each drive sprocket tooth is convexly arched and forms a crown transversely to the direction of movement.

摘要： Provided is an interlocking chain unit that has reliable and strong interlocking and avoids buckling, breaking, and bending of a rigidified chain portion. In the interlocking chain unit (100), the interlocking operation of an outer tooth link plate (112BZ) and an outer tooth link plate (112AY) that are just about to complete the interlocking operation is completed in a manner that causes a first inter-pin distance (d1) and a second inter-pin distance (d2) become substantially equal to each other, and causes a third inter-pin distance (d3) to approach the second inter-pin distance (d2).

摘要： A power steering apparatus including a rack gear and a pinion gear that are disposed within a housing and preloaded by a yoke assembly. The yoke assembly includes a bushing that is biased into engagement with the rack. A yoke plug extends through a yoke opening to provide a gear mesh load on the rack through the bushing assembly. The yoke body is axially assembled through a rack gear bore in the housing of the steering gear and a yoke assembly is inserted through a yoke bore to apply mesh preload to the bushing assembly. A method of making the yoke assembly by forming leaf springs that are over-molded to form a yoke body.

摘要： The invention relates to a pusher device (8) that includes a rotary bearing (10) having an inner periphery (11) that is off-center relative to the outer periphery (12). In order to compensate for wear, the bearing (10) is rotationally urged in one direction (F) by a spring (10) and is thus pressed against the back (9) of a rack (3) that is then pushed back against the teeth of the steering sprocket (5). The rotary bearing (10) is rotatingly mounted in a housing (13) that is in turn mounted on a steering casing (2) so as to be capable of sliding in a direction (B) parallel to a plane (P) of the teeth (6) of the rack (3) and orthogonal to the axis (A) of said rack. Shock-absorbing spring means (20, 21) are arranged between the sliding housing (13) and the steering casing (2) for absorbing the straightness defects of the rack (3).
