Abstract: A drive transmission device according to one embodiment of the disclosure includes: an arm having a motor that generates a rotational force; a speed reducer that is provided in the arm and has a carrier for decelerating rotation of the motor and outputting the decelerated rotation; a bucket fixed to the carrier by a reamer bolt, the reamer bolt being inserted in a bracket through hole formed in the bucket; and a resin bush provided between an internal surface of the bracket through hole and an external lateral surface of the reamer bolt. The mechanical strength of the resin bush is lower than the mechanical strength of the bucket and the mechanical strength of the reamer bolt.

Abstract: Embodiments of a system, method and apparatus for a gear are disclosed. For example, a metallic gear hub can include an axis of rotation and metallic gear teeth. The metallic gear teeth can be smaller than a final gear teeth size of the gear. The metallic gear teeth can be co-planar with the axis. In addition, the metallic gear teeth can be non-orthogonal to the axis. A polymer layer can be located on the metallic gear teeth to form polymer gear teeth on the metallic gear teeth. The polymer gear teeth can form the final gear teeth size of the gear.

Abstract: An example robot includes: a motor disposed at a joint configured to control motion of a member of the robot; a transmission including an input member coupled to and configured to rotate with the motor, an intermediate member, and an output member, where the intermediate member is fixed such that as the input member rotates, the output member rotates therewith at a different speed; a pad frictionally coupled to a side surface of the output member of the transmission and coupled to the member of the robot; and a spring configured to apply an axial preload on the pad, wherein the axial preload defines a torque limit that, when exceeded by a torque load on the member of the robot, the output member of the transmission slips relative to the pad.

Abstract: A vehicle having a pair of electric actuators for use with a pair of drive apparatuses is disclosed herein. For each actuator, an electric motor drives a reduction gear train to position a control shaft, the reduction gear train having a worm drive that motivates a spur gear reduction. The housing of the electric actuator features a motor chamber to accommodate the electric motor and is sealed by a cap having an electric connector.

Abstract: The present disclosure relates to a drill tool (1), such as a core drill tool (1), comprising a motor unit (2) and a gear unit (3). The motor unit (2) comprises an electric motor (4) and a motor drive shaft (5) that extends along a first longitudinal axis (6) from the electric motor (4) and protrudes out of a motor unit housing (7) via a motor exit aperture (8) in a housing end part (9) and comprises a drive shaft gear (10). The drive shaft gear (10) is adapted to propel a drill shaft (14) that extends along a second longitudinal axis (15) and comprises a tool holder (16) that is adapted to hold a tool. The housing end part (9) comprises a wall part (17) arranged transversally to the longitudinal axes (6, 15) and is adapted to close the gear unit cavity (11) and to separate the electric motor (4) from the gear unit cavity (11).
