Motion control apparatus (A) includes a direct coupled torque motor (54) slideably receiving an output (50) without other types of torque transmission devices between the output (50) and the motor (54) and between the output (50) and a pinion (7) in direct gearing engagement with an annular gear (44) connected to a second race (32) of a bearing (26) intermediate an annular mounting plate (38) and a dial plate (40). The second race (32) is a single, non-separable piece having L-shaped cross sections to define a mounting pilot for the annular gear (44). The motor (54) is secured to a mount plate (58) having an integral annular spacer (60) extending through a mounting tab (16) and secured to a mount ring (62) adjustably connected to the mounting tab (16) opposite to the mount plate (58).

The second race (32) is a single, non-separable piece having L-shaped, radial cross sections to define a mounting pilot for the annular gear (44). The motor (54) is secured to a mount plate (58) having an integral annular spacer (60) extending through a mounting tab (16) and secured to a mount ring (62) adjustably connected to the mounting tab (16) opposite to the mount plate (58).
A robot compliance device includes first and second discs (12, 30) spaced along a first axis (X). A column (24) is interconnected between the first disc (12) and a beam (14) intermediate the first and second discs (12, 30). A compliance member (40) is mounted around the column (24) between the first disc (12) and the beam (14). First and second canted resilient plates (50) are interconnected between the compliance member (40) and the beam (14) and spaced from each other along a second axis (Y) perpendicular to the first axis (X) and are at a first acute angle with and spaced from the first axis (X). Third and fourth canted resilient plates (52) are interconnected between the second disc (30) and the compliance member (40) and spaced from each other along a third axis (Z) perpendicular to the first and second axes (X, Y) and are at a second acute angle with and spaced from the first axis (X).

A linear motion brake (10) includes a channel shaped shoe guide (90) straddling a linear race (20) and having shoe bores (95) defined in leg plates (92) for receiving brake shoes (12). A piston (100) is reciprocally received in a piston cavity (86) of a plate-shaped housing (80) secured to the shoe guide (90). The piston (100) includes first and second protrusions (76, 134) extending from the piston head (102) in the reciprocation direction. Springs (114) are sandwiched between the shoe guide (90) and the piston (100). Ribs (116) of the piston (100) are slideably received in cutouts (96) formed in the connecting plate (94) of the shoe guide (92). Reciprocation of the protrusions (76, 134) cams the brake shoes (12) against the linear race (20).
A motion control apparatus ( 10) in the form of a linear brake includes a camshaft (23) rotatable in a housing (11) moveable along a linear rail (30). The camshaft (23) is rotated by a gear motor (15) causing an eccentric engagement portion of a cam follower (24) to abut with a facing (12) which engages the linear rail (30) to provide a clamping force thereon. A damper (25) is received on a dowel pin (14) secured to the housing (11) and received in a U-shaped groove in the camshaft (23) to inhibit further rotation of the camshaft (23). A shim (20) separates the outer races of the bearings (22) receiving the camshaft (23) to preload the first and second bearings (22).

A brake (10) having application for a linear or rotational motion device includes a housing (120) in which a first piston (140), a wedge (142) and a second piston (144) cooperate to engage a friction facing (136) through a plurality of rollers (152, 154, 156, 158). The three part piston assembly (148) allows a braking action and prevents torsional forces that are non-axial to the axis of the first piston (140) and second piston (144). The pistons (140, 144) are biased by compression springs (176) and may be actuated by a fluid.
A motion controller (10a) for use with a rod (14) has a backlash reducer (88A) that substantially reduces or eliminates the space created after manufacturing parts with specified tolerance dimensions to substantially reduce or eliminate backlash. The backlash reducer (88A) can be in the form of a holder such as an internal retaining ring (78) and a shim (36), a threaded cap, or the like to accommodate various part size variances due to manufacturing tolerances. Alternately, the end cap (44) of the motion controller (10A) can have an outside thread that mates to an inside thread of the inside surface of a housing (26). The motion controller (10A) has a friction collar (12) to hold the rod (14) under the action of balls (16) and a piston (18). The motion controller (10A) can be fluid powered with a fluid such as air.
