Embodiment Construction

[0014] A motion control device A is shown for providing precise positioning, particularly precise rotational positioning between two assemblies. In particular, apparatus A in the form shown includes a mounting plate 38 having parallel spaced and planar faces 14a and 14b. In the form shown, the plate 38 is annular in shape and generally circular in shape. Plate 38 includes a mounting tab 16 extending radially outwardly from the outer periphery of the circular profile and including a perforation 18 extending between faces 14a and 14b.

[0015] The device A also includes a bearing 26 comprising several rotating elements 28 located between an inner ring 30 and an outer ring 32 . The inner race 30 has parallel spaced apart and planar first and second ends 30a and 30b, and in the form shown is annular in shape. The first end 30a abuts against the face 14a and the inner ring 30 is fixed to the mounting plate 38 , for example by bolts 33 passing through the inner ring 30 from end 30...

Abstract

The motion control device (A) includes a direct coupled torque motor (54) slidably receiving an output member (50), between said output member (50) and said motor (54) and between said output member There is no other type of torque transmission between (50) and a pinion (7) which meshes directly with a ring gear (44) connected to the The second ring (32) of a bearing (26) in the middle of an annular mounting plate (38) and a table plate (40). Said second ring (32) is a single inseparable part having an L-shaped radial cross-section to define a mounting guide for said ring gear (44). The motor (54) is secured to a seat plate (58) having an integral annular spacer (60) extending through a mounting piece (16) and secured to a seat A ring (62) is adjustably connected to the mounting piece (16) opposite the seat plate (58).

Description

Background technique [0001] Illustrated and described is a motion control device, particularly a device that provides precise positioning, and more particularly, a precise rotational positioning between two components. [0002] In many applications, including but not limited to medical, semiconductor manufacturing, satellite tracking and welding, precise positioning is required between two components. Traditionally, precise positioning has been accomplished using cam-actuated systems. Such cam-driven systems have several disadvantages, including complexity, backlash, high power requirements, etc., and high costs in manufacture, operation and maintenance. Therefore, solutions are being sought to provide precise positioning and overcome the disadvantages of conventional cam-driven systems. [0003] US Patent No. 6,023,989 provides a transmission that has been commercially successful. What is needed is an application of gearing such as that shown in US Patent No. 6,023,989 in ...
