摘要:
Bremsvorrichtung für Linearantriebe zur Befestigung an einem gegenüber einer Gegenreibfläche (9) translatorisch verschieblichen Maschinenelement, z.B. einem Schlitten, mit einem ersten (11) und einem zweiten (12) Spulenträger mit jeweils einer Magnetspule (27, 27'), wobei die Spulenträger (11, 12) über Befestigungsmittel (41) aneinander gekoppelt sind, mit einer gegenüber den Spulenträgern (11, 12) in Richtung auf die Gegenreibfläche verschieblichen Ankerscheibe (21) mit einem daran angebrachten Reibbelag (22), mit einer in jedem Spulenträger (11, 12) angeordneten Federsäule (35, 35'), die auf die Ankerscheibe drückt, und mit mindestens einer sich im wesentlichen in der Bewegungsrichtung beider Spulenträger (11, 12) erstreckenden Lamelle (51, 52, 53, 54), die die Ankerscheibe mit den Spulenträgern verbindet.
摘要:
An overload clutch has a driving and a driven coupling body (1, 2), axially oriented teeth (2a) and radially oriented teeth (15a), torque-transmitting bodies (10) which mesh with the teeth (2a, 15a), a thrust collar (3) for holding the torque-transmitting bodies (10) emmeshed with the teeth (2a, 15a), a spring arrangement (11) for stressing the thrust collar (3) in the meshing direction of the torque-transmitting bodies (10), as well as an adjusting nut (5) for adjusting the spring arrangement (11). In order to avoid difficulties in handling and to increase operational safety, the adjustment path of the adjusting nut (5) is delimited towards and away from the spring arrangement (11) by stops (1b and 13) and the length of the adjusting nut (5) is adapted to the stops.
摘要:
The invention pertains to a backlash-free overload clutch having one driving and one driven clutch body (15 and 5) which rotate about the same axis and are torque transmittably connected with each other by means of torque transmission bodies (11) which are pressed by springs (7, 8, 12) into facing recesses (18, 19) in the two coupling bodies (15 and 5) in the direction of the parting plane which runs axially, radially or obliquely. In order to allow the clutch to race freely after the set maximum torque has been exceeded, a permanent or electro-magnet counteracting the force of the springs (7, 8, 12) is provided which, at least when the clutch is disengaged, counters the spring force to keep the torque bodies (11) out of at least one of the series of recesses (18 or 19).
摘要:
Disconnecting overload clutch, comprising a hub (5) which has axially directed hub recesses (4) arranged on the periphery thereof, a pressure flange (1) mounted on the hub (5) in a rotatable manner with axially directed pressure flange depressions (2), wherein in each hub recess (4), for example, two rotationally symmetrical transmission bodies (3,9) are arranged, which are pressed into the pressure flange depressions (2) by spring elements (6) via a switch element (7). According to the invention, the switch element (7) has axially projecting switch element cams (8) facing the front-end exposed surface (21) thereof, which in the engaged state transfer the force of the spring elements (6) to the transmission bodies (3,9) and thus axially engage with the hub recesses (4). When disengaging, the switch element (7) experiences an axial displacement and rotary movement with the switch element cams (8) in relation to the hub (5), so that the switch element cams (8) are transferred into a position wherein same transfer the force of the spring elements (6) only onto a support surface (20) of the hub (5) with the result that the clutch can freely come to a stop.
