Abstract
A braking device for a drive device of a joint between two links of a robot arm including a brake activating device and a locking element, wherein the brake activating device is designed to bring the locking element into engagement with a rotor of the drive device as required in order to halt rotation of the rotor, the locking element being designed as a bolt and the braking element being designed as a braking star with webs which have a defined impact surface for the bolt.
Claims19
A braking device for a drive device of a joint between two links of a robot arm comprising a brake activation device and a locking element, wherein the brake activation device is designed to bring the locking element into engagement with a braking element when required, which is connected to a rotor of the drive device in a rotationally fixed manner in order to stop a rotation of the rotor, the locking element being designed as a bolt and the braking element being designed as a braking star which comprises at least one web projecting radially from an axis of the rotor,
- characterized in that
- the web comprises an impact surface which interacts with the bolt when engaged, and which is curved inwards with respect to a direction of rotation of the braking star and comprises a radius (RA) which corresponds at least to a radius (DB/2) of the bolt, and in that the impact surface extends in the radial direction beyond a distance (LB) between the axis of the rotor and an axis of the bolt.
