    摘要： An electromagnetic clutch includes an armature to be attracted to a rotor, an armature hub formed on one end portion of a rotating shaft, and a leaf spring which connects the armature to the armature hub and biases the armature away from the rotor. The leaf spring includes a base fixed to the armature hub, a stopper connected to the base, and a connecting piece surrounding the stopper by projecting outside from the base, and fixed to the armature. A through hole into which a rivet for fixing the base to the armature hub is inserted is formed in the base. A low-strength portion having strength lower than that in the periphery of the through hole is formed in a boundary portion between the base and a connecting portion.

    摘要： The invention relates to a drive having an emergency closing function, comprising a movable coupling device, which has an emergency spring clamped between an input-side and an output-side spring system. The emergency spring is preferably a compression spring moved along with the coupling device. A distance of the spring systems is defined by means of a locking device in normal operation of the drive, wherein the emergency spring can relax for an emergency function or emergency movement of the drive after the locking device is released or unlocked. According to the invention, the locking device is operated or can be triggered hydraulically or pneumatically and/or magnetically.

    摘要： A resistive and locking system for locking rotation of a shaft, the system comprising: a housing (200) defining an axis AX therethrough, the housing (200) containing: a drive shaft (250) mounted in the housing and extending axially from a bottom end of the housing; a first stage comprising a resistive mechanism (210) provided in the housing around the drive shaft to resist rotation of the drive shaft relative to the housing; a second stage comprising a locking mechanism (230) arranged in the housing above the first stage, the locking mechanism biased axially to frictionally engage with and lock the first stage mechanism to prevent rotation of the drive shaft, the locking mechanism including a magnetic unlocking mechanism configured to remove the frictional engagement with the first stage on application of power to the locking mechanism.

    摘要： A roller clutch includes an outer race, an inner race, a first engagement member situated between the outer race and the inner race, a second engagement member situated between the outer race and the inner race, and an electromagnetic mover to be energized or de-energized. The first engagement member is configured to engage the outer race and the inner race to transmit torque between the outer race and the inner race in response to the electromagnetic mover being energized and the inner race applying negative torque to the second engagement member while the outer race applies positive torque to the second engagement member. The second engagement member is configured to engage the outer race and the inner race to transmit torque between the outer race and the inner race in response to the inner race applying positive torque to the second engagement member while the outer race applies negative torque to the second engagement member.
