Abrégé

The invention relates to a component (1) produced by powder metallurgy, having a body (2) and a toothing (3) comprising a plurality of teeth (5). A tooth gap (12) having a gap base is formed between two tooth flanks of two adjacent teeth (5), which face each other in the circumferential direction (4). The gap base connects the two mutually facing tooth flanks to one another. In the circumferential direction (4), the toothing (3) has a compaction region which has a higher density as compared with the density of the whole component (1). A bottom section of the gap base is a constituent part of the compaction region, in such a way that the compaction region has a higher density as compared with the density of an adjacent bottom section of the gap base in the circumferential direction (4).

Abrégé

The invention relates to a method for forming a surface relief on an available surface of a compacted sintered component which forms the workpiece, using a forming element that is moved in the working direction towards the available surface. The working direction runs radially in relation to the workpiece and a contact surface of the forming element. The shape of the surface having the relief is applied to the surface of the workpiece in the working direction.

The invention relates to a method for forming a surface relief on a available surface (21) of a compacted sintered component which forms the workpiece (4), using a forming element (3) that is moved in the working direction (22) towards the available surface (21). The working direction (22) runs radially in relation to the workpiece (4) and a contact surface of the forming element (3), the shape of said surface (5) having a relief (20), is applied to the surface (21) of the workpiece (4) in the working direction (22).

The invention relates to a tool (1) for machining a workpiece (4). The tool (1) contains a tool element (3) that can be moved in the working direction (22) in order to be applied to a surface (21) of the workpiece (4). A drive element (19, 19a, 19b) that can be driven in a drive direction (24) transversally to the working direction (22) of the tool element (3) interacts with the tool element (3) to transmit a force. A transmission element (2, 2a, 2b) for transmitting force between the drive element (19, 19a, 19b) and the tool element (3) is positioned between the tool element (3) and the drive element (19, 19a, 19b).

Synchronism system for a vehicle power transmission mechanism, of the type which makes an elastic connection between a sliding clutch sleeve (1) and a synchronizer hub (2) of said power transmission mechanism. The locking device (11) is formed by at least one casing (3), which houses therein at least one elastic element. The casing (3) contacts with the synchronizer hub (2) being disposed in a housing (5) made in the periphery thereof, and the elastic element is a torsion spring which exerts tension between the clutch sleeve (1) and the synchronizer hub (2).
