摘要： A telescopic transmission assembly includes first and second stage rods, and first and second stage casings. The second stage rod is of a hollow structure having inner and outer surfaces and a through hole, the outer surface being provided with external threads, and the inner surface being devoid of threads. The first stage rod is disposed in the through hole to drive the second stage rod to rotate synchronously. The first and second stage rods are telescopically expandable or contractible relative to each other along an axial direction. The second stage casing sleeves over the first stage casing. The first and second stage casings have respectively first and second transmission nuts. The second and first stage rods are in a screw-thread fit with the first and second transmission nuts, respectively. The second stage rod is positioned with the first transmission nut in the axial direction in a rotatable manner.

摘要： Machining tool comprising a frame in which a drive shaft for a tool is mounted so as to pivot about a rotation axis and to move axially along the rotation axis. The shaft is connected to two rotary motors, namely a first motor connected to a member for meshing with a fluted portion of the shaft in order to drive the shaft in rotation and a second motor connected to a nut engaged with a threaded portion of the shaft in order to move the shaft axially. The motors are connected to at least one control unit designed to control the motors independently of one another, and the first motor and the second motor are coaxial with one another.

摘要： A splined ball screw assembly having a nested structure is provided. A hollow shaft extends into an outer sleeve and a center shaft extends into the hollow portion of the hollow shaft. A ball screw structure is provided at either side of the outer and inner peripheral surfaces of the hollow shaft and a ball spline structure is provided on the other side. The outer sleeve is rotatably mounted on a housing and the center shaft is also rotatably mounted on the housing. By controlling the amount and direction of rotation of both of the outer sleeve and the center shaft, the hollow shaft may be moved longitudinally in a desired direction and/or set in rotation. The present assembly is compact in size and particularly suitable for use in a robot arm.

摘要： Motion transmitting systems for machinery and machine tools wherein the combination of rotary and linear movement of a spindle is utilized to perform tasks especially drilling, reaming, tapping, and punching of metal. The tool supporting spindle is longitudinally threaded and powered at a preset, variable, rotary velocity. The spindle threads mesh with a linearly restrained longitudinally threaded member independently powered at a preset, variable, rotary velocity such that dissimilar angular velocities between the spindle and threaded member transmit precisely controlled advancing and retracting movement of the spindle.

摘要： Apparatus is disclosed for imparting to a shaft either rotation or translation or both, by the rotation of one or both of two gears within the apparatus. Translation is provided by the rotation of a first gear having internal threads, which threads match a toothed rack superimposed upon a shaft which passes through the gear. Rotation of the shaft is provided by rotation of a second gear which is slotted to match the shaft and rack which passes through the second gear. The separate elements of first gear, second gear and racked shaft are each held in position relative to the other elements so as to allow desired movement of the elements while restraining all other movements.

摘要： A mechanical quill and spindle drive mechanism is disclosed wherein the quill is advanced by means of a screw formed about its periphery and cooperating with a driven ball nut. The quill is received within a housing bore and accurately guided for longitudinal movement thereby by means of a sliding engagement with bore surfaces on either side of the nut. The spindle is carried by the quill throughout its longitudinal movement and is rotated by means of a splined drive shaft which maintains a rotative connection therewith by means of a splined connection therebetween.

摘要： A drive arrangement in a pneumatic power tool includes a pneumatic motor with an output shaft, and a spindle for mounting a cutting element and which externally includes both a thread and an axial groove. A drive rotation of the spindle is driven by a drive gear that is engaged with the axial groove on the spindle and that is drivingly connected to the output shaft so as to rotate at a constant speed with respect to the output shaft. A feed gear is threaded upon the spindle and may be rotated with respect to the spindle in order to advance and retract the spindle. The feed gear is driven by one intermediate feed gear which is interchangeably drivingly connectable to the output shaft via a first and a second gear connection, respectively, so as to advance or retract the spindle.
