摘要:
A gas turbine engine (20) according to an exemplary aspect of the present disclosure includes, among other things, a compressor section (24), a combustor section (26), a turbine section (28), and at least one rotatable shaft (72). The engine further includes a seal assembly (64) including a seal plate (76) mounted for rotation with the rotatable shaft and a face seal (74) in contact with the seal plate (76) at a contact area (80). The seal assembly (64) further includes an abradable coating (90) adjacent the contact area (80). The abradable coating (90) includes magnetic particles embedded in a polymer material.

Vorgeschlagen wird ein Kupplungsring (52) einer Zustelleinrichtung für eine Fahrzeug-Scheibenbremse, die zum Ausgleich des betriebsbedingten Verschleißes an den Bremsbelägen und der Bremsscheibe mit einer Nachstelleinrichtung versehen ist. Der Kupplungsring (52) ist mit einer Ringöffnung, einer stirnseitigen Ringfläche (62) und mindestens einer weiteren Ringfläche (74) versehen, die mit Kupplungsstrukturen in Gestalt von gleichmäßig über den Umfang verteilt angeordneten Rampen (71) versehen ist. Die weitere Ringfläche (74) ist konisch in Bezug auf die Achse (A) des Rings angeordnet. Die Ringöffnung ist über ihren Umfang mit radial zu der Achse (A) vorspringenden ersten (56) und demgegenüber zurückspringenden zweiten (57) Umfangsabschnitten versehen, die einander abwechseln.
摘要:
The invention relates to a valve for a motor vehicle, comprising a control member (14) that can rotate in relation to a stationary frame (20) of the valve, the rotation of the control member (14) controlling the opening of the valve. In addition, a bearing comprising two rings (30a, 30b) that can rotate freely in relation to one another (30) is mounted between the stationary frame (20) of the valve and the control member (14). The stationary frame (20) forms a housing (50) for receiving the bearing (30), said housing having a base (52) and a side wall (54) extending essentially along the axis of rotation (A) of the sector gear (14). The housing comprises, over at least one angular sector, one edge (56) of the side wall (54) that is folded onto a ring of the bearing in order to limit, together with the base (52) of the housing, the movements of the ring along the axis of rotation (A) of the control member (14).
摘要:
An objective of the invention is to provide a work apparatus in which the maximum value of the force acting on a work object is unchanged even when the size of the object varies, the work apparatus not exerting force in excess of a prescribed value. The work apparatus is provided with a first member (1) and a second member (2), at least one of which is moveable, and is additionally provided with a work part (3) operated by movement of the first member (1) or the second member (2). Either the first member (1) or the second member (2) is furnished with a mobilization part (4) and a mobilized contact part (5), while the other is furnished with a contact receiving part (6). When the operating resistance of the work part (3) reaches a prescribed value, the mobilized contact part (5), having been mobilized in a direction different from the direction of movement prior to contact due to deformation of the mobilization part (4), comes into contact against the contact receiving part (6), and in this state of contact of the mobilized contact part (5) against the contact receiving part (6), force further applied to the moveable first member (1) or the second member (2) is not transmitted to the work part (3).
摘要:
A flexible compression screw having multiple segments, one or more of which are flexible and one or more segments that also include threads. The flexibility is created through the use of at least one helical slot formed generally in the center segment of the element. Additional flexible segments also have at least one helical slot in either the same helical rotation and pattern or in an opposite rotation and/or different pattern. An elastomeric material can fill the hollow body, extend into the slots and/or encompass the exterior. The flexible screw can have a hollow body, including leading and trailing edge, or can have a partially hollow body.
摘要:
A translation table with a pair of bearing assemblies (30) located between a first element (12) and a second element (14). Each bearing assembly has a pair of roller bearings located at one end of a bearing separator strip, and another pair of roller bearings located at an opposite end of the separator strip. There are no bearings located between the outer pairs of roller bearings. Providing a roller bearing assembly with no roller bearings in the inner portion of the separator strip creates a relatively stiff bearing assembly.

The invention relates to a hand propelled transport cart (1), comprising a chassis (2) with rollers (3) and a pushing device (8), supported by bent spars (6), functionally co-operating with at least one of the rollers (3) by means of a bar (10). The bar (10) runs to the at least one roller (3) from the pushing device (8) within the spar (6), whereby said bar (19) is embodied by at least one jointed intermediate piece (17). The invention is characterised in that at least one further intermediate piece (17) is provided and that the intermediate pieces (17) are jointed to each other in series.
