Abstract: 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).

Abstract: Disclosed is a pin clutch connection structure of an anti-panic gear box, wherein the transmission of rotation to a driving motor which is mounted on a gear box is blocked when rotational force is applied from the outside (manual opening and closing of a door lock), so as to prevent a driving circuit in the gear box from being damaged and to enable manual opening and closing even with a small amount of force.

Abstract: The invention relates to a method for the transverse drawing of an unoriented or longitudinally-oriented film web made from thermoplastic plastic. According to said method, an undrawn or longitudinally-drawn film (8) is introduced into a transverse drawing frame in which heater fields (1) are heated to a transverse drawing temperature TQ, in the attached drawing fields (2) a clip chain is drawn in the transverse direction by divergent (V-shaped) guides and a temperature TF is applied to fixing fields where TQ>TF. In the drawing fields and/or the heating fields (1) the boundary zones (5) of the film (8) are heated or thermally insulated such that the boundary zones (5) of the film (8) have a higher temperature than the middle of the film web (6) on transverse drawing and/or fixing.

Abstract: A rotation urging mechanism includes: an outer member which has an outer raceway surface on its inner periphery and is rotatable about a first axis; an inner member which has on its outer periphery an inner raceway surface disposed in face-to-face relation to a radially inner side of the outer raceway surface over an entire circumference thereof and is rotatable about the first axis; and a plurality of balls disposed rollably between the outer raceway surface and the inner raceway surface. The outer raceway surface is formed about a second axis which is inclined with respect to the first axis, and the inner raceway surface is formed about a third axis which is inclined with respect to the first axis.

Abstract: A centrifugal advance mechanism has drive and driven members connected with one another to rotate about a common axis as they move toward and away from each other along the common axis. A resilient element biases the members toward each other. A ramp on one of the members has an inner end portion and an outer end portion. The inner end portion is closer to the common axis than the outer end portion, the ramp rising as it moves from the inner end portion toward the outer end portion. A ba1l contacts the ramp and the other member. The resilient element biases the ball down the ramp, the ball traveling radially outward and up the ramp as the members rotate at increasing angular velocity thereby causing the members to separate from each other against the bias of the resilient element and to rotate with respect to each other.

Abstract: A decoupling mechanism for a power tool having a motor driving a drive shaft that drives a rotating component includes a shaft gear disposed around the drive shaft. The shaft gear has a first side and a second side. The second side has at least one shallow receiving structure and at least one deep receiving structure. At least one friction plate is disposed on the drive shaft adjacent to the first side. At least one pressure plate is disposed on or integrally part of the drive shaft adjacent to the friction plate and configured for rotation with the drive shaft. A spring assembly is biased against the shaft gear. The spring assembly includes a plate disposed around the drive shaft and a spring member. At least one cam is disposed between the plate and the shaft gear, and is configured to engage with the shallow and deep receiving structures.

Abstract: It is an object of the invention to provide an effective technique for improving the durability of a torque limiter utilized in a power tool. The object is achieved by a representative power tool comprising a tool bit, a driving mechanism and a torque limiter. The torque limiter includes first and second rotating members, a ball, a pressing member and an elastic member. The second rotating member includes a power transmitting region with a groove continuously formed from a deepest groove part to a shallowest groove part to allow torque transmission and a power transmission interrupted region with a groove shallower than the shallowest groove part of the power transmitting region to interrupts the torque transmission. According to this construction, when the ball is in the power transmitting region, the pressing member contacts the first rotating member and is held in a position in which the biasing force of the elastic member is prevented from acting upon the ball.

Abstract: A power tool including a drive assembly including a first clutch assembly having an engaged configuration, in which the first clutch assembly transfers a drive force from a motor shaft to a spindle, and a disengaged configuration, in which the first clutch assembly prevents the transfer of the drive force. The first clutch assembly can be movable toward the disengaged configuration when a torque exerted on the spindle exceeds a torque limit. The drive assembly can also include a second clutch assembly having an engaged configuration, in which the second clutch assembly transmits the drive force from the motor shaft to the spindle, and a disengaged configuration, in which the second clutch assembly prevents the transmission of the drive force. The second clutch assembly can be movable toward the engaged configuration when the tool element engages a workpiece.

Abstract: A torque limiter limits transmission of torque between a drive shaft and an output shaft. The torque limiter includes a first rotational plate connected to the drive shaft, a second rotational plate facing the first rotational shaft and connected to the output shaft to be movable along an axial direction thereof, a ball ramp portion provided between the first rotational plate and the second rotational plate, a ball retained in the ball ramp portion, and a spring portion for pressing between the first rotational plate and the second rotational plate. A ball channel is formed in at least one of the first rotational plate and the second rotational plate. The ball in the ball ramp portion falls in the ball channel when the torque between the drive shaft and the output shaft exceeds a predetermined value to shut off the transmission of the torque.

Abstract: A torque limiting coupling defines a longitudinal axis (17) and has a coupling hub (8) with circumferentially distributed through holes. Transfer elements are adjustably held in the holes. A coupling sleeve (6) has first recesses corresponding to the through holes. A switching disk (9) is arranged relative to the coupling hub (8) between a torque transmitting position and a freewheeling position. The switching disk (9) is urged towards the torque transmitting position. This urges the transfer elements in the direction towards the coupling hub (8). The transfer elements engage, for torque transmission, in recesses of the coupling sleeve (6). Coupling sleeve (6), when a predetermined nominal torque is exceeded, is transferable from the torque transmitting position to the freewheeling position. Second recesses, corresponding to the through holes, receive the transfer elements in the freewheeling position.
