摘要： An apparatus for adjusting the relative positions of a first component and a second component of a power tool includes a drive rod which interconnects the first and second component. The drive rod has a plurality of external threads in meshing engagement with a plurality of internal threads located on one of the first and second components. An internally threaded element preferably in the form of a backlash nut is also in meshing engagement with the plurality of internal threads. A biasing member is interdisposed between the internally threaded element and one of the first and second component. In a preferred form, the apparatus is incorporated into a power tool for woodworking or metal forming and is operative for eliminating play in the threaded interconnection of the components which is most evidence upon reversal of movement of the drive rod.

摘要： A mechanism to linearly drive an object has a driven member and a magnetic coupling--with first and second mutually facing elements which transmit longitudinal force but allow relative lateral motion that may be translational or rotational. In one form of the device a flange extends from one element, along a direction including a longitudinal component, to engage--through the intermediary of a set of balls--a surface on the other element. The surface and flange cooperate to constrain the two elements against relative lateral motion in at least one direction. Magnetic fields clamp the balls between the flange and surface, to eliminate play perpendicular to the surface, and permit relative motion parallel to the surface. Two stages in series transmit torque through the system but absorb transverse translational wobble. Another form of the device also absorbs transverse rotational wobble: instead of flange and surface, the coupling has two curved surfaces (which may be cylindrical or spherical) and balls between them. A driving member can be added, moving the driven member longitudinally when the driving member rotates; either is elongated.

摘要： A rotatable drive mechanism for producing linear motion of an object includes driving and driven members, one of which is elongated, and which act cooperatively through frictional engagement to produce longitudinal motion of the driven member. It also includes a magnetic coupling having at least first and second magnetizable members with mutually facing flat annular surfaces, a set of balls disposed in a generally annular arrangement between those flat surfaces, and magnetic means attracting the magnetizable members to each other. Respective ends of the magnetic coupling are fixedly secured to the driven member and to the object, respectively. Since the elements of the magnetic coupling, in and of themselves, would permit relative rotation of parts, which is undesired, provision is also made for restraining the undesired rotation of any part of the magnetic coupling. In a particular embodiment a second magnetic coupling, without balls between magnetizable members, is also used in opposing relation to the first coupling.

摘要： In a feed screw apparatus composed of a feed screw shaft and a nut engaged with the feed screw shaft which is movable in the axial direction, a guide rail member having ball rolling grooves in both side surfaces is disposed beneath the feed screw shaft in parallel to and slightly spaced therefrom. The bottom portion of the nut is extended downwardly at both lateral sides to form side walls constituting a linear guide section which sandwiches the guide rail member and has ball rolling grooves in the inner surfaces of the side walls. The outer surfaces of the side walls of the linear guide section are formed with ball rolling grooves, and half tubes respectively facing these ball rolling grooves to form ball return paths are fixed between end caps which are secured at opposite ends of the linear guide section.

摘要： A slip clutch assembly has a push-pull rod on link and a motor driven threaded lead screw shaft which screws in and out of a threaded bore in the push-pull rod. A plastic generally cylindrical nut is interposed between the lead screw shaft and the bore in the push-pull member. The nut has spaced apart external rings which register in corresponding grooves in the bore in the push-pull rod. The nut has internal threads in which the lead screw turns. If the nut is prevented from moving axially by engaging the push-pull rod with a stop or load the rings on the nut slip on the grooves to prevent overload of the drive system and continued extension of the push-pull rod.

摘要： A direct-acting table mechanism in which tables are driven without any contact by use of a hydrostatic fluid for thrust-transmitting the tables in their sliding direction. The tables are hydrostatically supported on hydrostatic guides on a bed, and differential pressures are supplied to the hydrostatically supporting portions to control the attitude of the tables. This table mechanism is of high degree of accuracy uninfluenced by errors in the feed screw system, high rigidity and thus permits highly stable fine feed.
