Abstract:
A motorized drive system and method for articulating an articulated joint having a motor and an elastic cable. The elastic cable is operatively connected to both the motor and the articulated joint such that the motor articulates the joint via the elastic cable. In addition, the elastic cable is adapted to be sufficiently elastic such that the motorized drive system is configured to use one motor for each degree of freedom through which the articulated joint moves.
Abstract:
A combination linear and circular motion roller bearing assembly having a rail (16) and a pair of tracks (24), each located along a side wall of a rail. The rail forms a contiguous path having both linear and circular portions. A slider bearing assembly (100) is movably attached to the rail. The slider bearing assembly has internal contiguous paths (28) that correspond to the tracks. Each internal path has an opening adjacent the corresponding track and a tapered insert (32) therein for exposing a predetermined number of ball bearings (22) to the track to allow rolling movement with respect to the track as the slider bearing assembly moves along the rail.
Abstract:
To reduce the lift travel with a simple end position-recognition device which is reliable even on emergency manual operation and can be retrofitted, a radially projecting cam (2.7) connected to a drive shaft (2) of the drive unit engages during one revolution from tooth to tooth with the inner toothing of a ratchet (11) rotatable about and concentric with a spindle (11.1) offset parallel to the drive shaft (2). The cam (2.7) has an axial lift such that it can mesh with the ratchet (11) even with an axial shift of the drive shaft (2) in the event of emergency actuation.
Abstract:
A linear drive apparatus (10) for moving a carton (175) in a packaging machine from a first position to a second position is set forth. A first drive belt (115) is connected to a drive roller (75) and disposed about the drive roller (75) in a clockwise direction at a first end thereof while a second end of the first drive belt (115) is connected to a first position of an engagement assembly (15). A second drive belt (95) is connected to the drive roller (75) and disposed about the drive roller (75) in a counter-clockwise direction at a first end thereof while a second end of the second drive belt (59) is connected to a second portion of the engagement assembly (15) opposite the first portion of the engagement assembly (15). The rotation of a drive shaft (80) in a clockwise direction causes linear movement of the engagement assembly (15) in a first direction along the guide rods (50) and the rotation of the drive shaft (80) in a counter-clockwise direction causes linear movement of the engagement assembly (15) in a second direction opposite the first direction.
Abstract:
A motor (20), a ball screw shaft (12) and so forth are accommodated in a frame (18) constituting an outer frame, and direct-drive guides (23) are provided on both sides of a groove-like opening (22) formed in this frame. The ball screw shaft (12) is provided at the central portion of the frame (18), and a table (16) slides along the direct-drive guides (23) by virtue of rotational action of the ball screw shaft (12). A ball screw spline (26) is provided along the full length of the ball screw shaft (12), which is supported at the ends thereof by means of the motor (20) and the bearing (14), respectively. The rotational centers of the ball screw shaft (12), motor (20) and bearing (14) are aligned with each other by means of balls (32) inserted into the spline (26).
Abstract:
The present disclosure provides differential drive assemblies and methods of making and operating differential drive assemblies. The differential drive assembly includes a rotor having a rotor axis about which the rotor is configured to rotate. The rotor has a peripheral wall portion encircling the rotor axis that is positioned a varying distance radially outward from the rotor axis. The differential drive assembly also includes a base coupled to the rotor. That includes a first plurality of pulleys and a carriage movably coupled to the base that includes a second plurality of pulleys and is movable with respect to the base. The differential drive assembly includes a rope wound about the rotor. The rope extends from the peripheral wall portion of the rotor to the second plurality of pulleys. The rope extends from the second plurality of pulleys to the first plurality of pulleys to form a continuous rope circuit.
