摘要： The main-spindle drive disclosed comprises at least two electric motors located equiaxially one behind the other. Only the stator (1) of one of the electric motors at the front (i.e. tool) end of the row of motors is rigidly fixed. The stators (3) of the other motors are rotatably mounted in the housing (2). The rotor (4) of each motor is mechanically linked rigidly to the rotatably mounted stator (3) of the next motor as viewed from the tool end. The rotors (4, 13) are fitted on coaxially mounted shafts (5, 6) which extend out at the tool end and have connector points for a tool holder (14). The rotor (4) at the front of the line of motors is connected to the outer, tubular shaft (5), and each of the subsequent rotors (13) is connected to the next in a series of shafts (6) lying successively inside the previous one. The bearings (7, 8) of the front motors are located between the housing (2) and the outer, tubular shaft (5), while the other bearings (11, 12) are located between the neighbouring coaxial shafts (5, 6). This design enables the tool to be run at high rpm while the bearings (7, 8, 11, 12) rotate at low rpm.

摘要： A portable driving device (10) for rotationally driving a ski course gate (80) into a snow covered surface includes a drive member (62) rotatable about a longitudinal axis. The drive member defines a longitudinal channel (64) configured to receive a pole portion (82) of the ski course gate. A gate engaging structure (66) is connected to the drive member and is adapted to form a torque transferring engagement with an auger portion (84) of the gate. A rotational transference assembly (14) is operably connected to the drive member. The rotational transference assembly is adapted to transfer a rotational input from a rotational power source (48) to the drive member causing the drive member to rotate about the longitudinal axis.

摘要： This invention relates to a machine tool having two main spindles which are subject to driving control by servomotors (1 and 2) by giving velocity commands (Vcmd1) and (Vcmd2) for controlling, respectively, the speed of rotation of a first main spindle and that of a second main spindle to speed control circuits (3 and 4), thereby controlling the two main spindles of a machine tool such as a lathe in synchronous operation in order to machine a work efficiently. In the present invention, the angles of rotation of the main spindles are brought into conformity to effect the synchronous operation without fail and to enable a catch of another work during rotation.
