摘要:
A gear is described for a spur gear stage without play having a hub (1) and a sprocket (2), which is divided along its axis-normal division plane into two partial sprockets, namely into a hub-fixed sprocket part (3) and a sprocket ring (4) which is mounted so it is coaxially rotatable in relation thereto, and which forms springs (6) sectionally enclosing the hub (1) in the circumferential direction, which are integrally connected at their bases (11) to the sprocket ring (4) and which are supported with their free ends (7) protruding toward the hub (1) on stops (8) of the hub (1). To ensure advantageous spring loads, it is proposed that the sprocket ring (4), which is mounted so it is rotatable on the hub (1), form at least three springs (6), which are arranged rotationally-symmetrically with respect to the sprocket axis, and the stops (8) of the hub (1), which are also arranged rotationally-symmetrically, have approach surfaces (10) for the free ends (7) of the springs (6), which rise radially outward in the circumferential direction toward the bases (11) of the associated springs (6).

摘要:
The invention relates to a toothed wheel arrangement (1) comprising a main toothed wheel (2) and a toothed wheel (4) that can be rotated relative thereto in the circumferential direction (3), wherein the main toothed wheel (2) comprises a toothed wheel body (25) on which a hub (5) is arranged in a projecting manner in the axial direction so as, firstly, to accommodate a shaft and, secondly, to arrange the rotatable toothed wheel (4) thereon, for which purpose the rotatable toothed wheel (4) has a cutout (17) coaxial to an axially extending center axis of the main toothed wheel (2), and wherein the main toothed wheel (2) is connected to the rotatable toothed wheel (4) by means of a bayonet fastening (14). The bayonet fastening (14) is formed between the hub (5) and the rotatable toothed wheel (2) and/or between the hub (5) and a spring element (9) bearing on the rotatable toothed wheel (4).

The invention relates to a bearing cover (3) for a split bearing arrangement (1) which, in addition to the bearing cover (3), comprises a bearing block (2), and the bearing cover (3) has a clamping surface (5) which lies against a co-operating clamping surface (6) of the bearing block (2) when the bearing arrangement (1) is in the assembled state, and at least one projection (7) is provided on the clamping surface (5) and protruding out from it which can be pushed into the co-operating clamping surface (6) of the bearing block (2). The at least one projection (7) has a cross-section (9) which varies across its extension on the clamping surface (5) and/or is of a conical or frustoconical or pyramid or truncated pyramid shape.

A plant (100) for the layered construction of a molded body comprises a coating device (400) and a coating device cleaner (600). The coating device is movable horizontally across a construction field for applying a uniform layer of construction material to be solidified to the construction field and has an elongate metering shaft (410), at the lower side of which a longitudinal slot (412) is provided for outputting the construction material as the metering shaft (410) moves across the construction field. The coating device cleaner (600) is mounted on a construction frame (150) of the plant and serves for cleaning the metering shaft (410). The coating device cleaner (600) comprises an elongate wiper element (610) that is received under the metering shaft (410) of the coating device (400) at least in part in a construction material collection container (620).

The invention relates to a synchronizer hub (1) comprising a hub body (4) that, on the outer circumference (5) thereof, has a sleeve toothing (6) for engagement of a sliding sleeve (6a), said sleeve toothing being interrupted by at least one first axial recess (7) and by at least one second axial recess (8), wherein the first axial recess (7) has first lateral faces (14, 15) and the second axial recess (8) has second lateral faces (17, 18), and wherein the first lateral faces (14, 15) are inclined to the axial direction at a first angle (20). The second lateral faces (17, 18) of the second axial recess (8) run at a second angle (21) to the axial direction, wherein the second angle (21) is not equal to the first angle (20) of the first lateral faces (14, 15).
摘要:
A power assist element for arrangement in a synchronizer hub of a transmission synchronization device includes a base body, which has a height, a longitudinal extension and a lateral extension, and which in the direction of the longitudinal extension comprises includes two opposite, distal end sections. In at least one end section a functional surface is formed, which in the installed state cooperates with the synchronizer hub. On the base body between the two distal end sections a central elevation is formed for engagement in a sliding sleeve groove on a bottom of a sliding sleeve. The central elevation includes at least one additional functional surface which can be brought into active connection with the sliding sleeve. The functional surface in the distal end section(s) is at an acute angle to the greatest longitudinal extension of the base body and oriented at an angle to the longitudinal extension.
