A first support member and a second support member are provided in a rotation support device and a worm gear is rotated in a state that the second support member is inserted in the first support member, whereby the worm gear is prevented from being shaken through the first support member and the second support member and heat transmission to a housing due to rotation of the worm gear to damage the housing is prevented.

An improved design and method is disclosed that uses a novel nesting linear slide which incorporates machine tool slides or ways into a structural member. The design simplifies the fabrication and assembly of components requiring accurate sliding alignment, such as milling machine bases, saddles, tables and columns. Due to the use of the single piece, which replaces multiple pieces in the prior art, fabrication and assembly costs are also significantly lower. The invention also enables a method of construction utilizing the novel single shape component which simplifies the assembly of machines requiring sliding surfaces with accurate alignment. The invention essentially comprises a single structural element that includes both male and female sliding members. By nesting two of the single structural elements it is possible to create sliding joints for machine tool bases, saddles, tables, and columns, as well as a wide variety of other sliding joints, in an extremely cost-effective manner. The linear slide includes a deformable element that allows for accurate alignment with no play and creates a strongly supported sliding joint.

The invention relates to a bearing cover (3) for a split bearing arrangement (1), which in addition to the bearing cover (3) comprises a bearing block (2), wherein the bearing cover (3) comprises clamping surfaces (7), which in the assembled state of the bearing arrangement (1) bear on counter clamping surfaces (8) of the bearing block (2), and the clamping surfaces (7) have a sinter-roughened surface at least in some areas.

A plurality of press rolls (33) each having an inclined roll central axis (6) are used. Each of press rolls (33) and a bub ring (22z) are relatively rotated while pressing a roll processing surface portion (34) of each of the press rolls (33) against a plurality of locations of a tubular portion (25) of the hub ring (22z) in a circumferential direction to plastically deform the tubular portion (25).

The simplicity and low cost of the method will be especially advantageous in the manufacture of small machine tools and other machines intended for higher volume production.

A rolling bearing includes an inner ring, an outer ring, a plurality of balls, and a cage that holds the balls. The inner ring is a rotating ring, and the outer ring is a fixed ring. An annular groove for creep suppression is formed in a fitting surface of the rolling bearing that is fitted on a mating member to which the outer ring is attached. The annular groove has a groove main body portion and inclined groove portions located on opposite sides of the groove main body portion in an axial direction and formed to be shallower than the groove main body portion such that the depth of each of the inclined groove portions increases toward the groove main body portion. The inclined groove portions come into contact with the mating member when the outer ring is elastically deformed by a radial load received from the balls.

A first support member and a second support member are provided in a rotation support device and a worm gear is rotated in a state that the second support member is inserted in the first support member, whereby the worm gear is prevented from being shaken through the first support member and the second support member and heat transmission to a housing due to rotation of the worm gear to damage the housing is prevented.

A concave portion provided in at least one of the first assembled surface, and other assembled surfaces for fastening the driving force source, in the region corresponding to the outer race of the tapered roller bearing, the other assembled surfaces provided to one of the fixed component and the driving force source.

A breakaway joint for a boom arm assembly includes a first boom segment defining a pivot axis at a first end, a second boom segment pivotally coupled to the first boom segment at the pivot axis, a bracket coupled to the first boom segment, a leaf spring coupled to the bracket between the first boom segment and the second boom segment, and a cam coupled to the second boom segment and positioned adjacent to the leaf spring. The first boom segment and the second boom segment are pivotally aligned in a neutral position. In the neutral position, the leaf spring contacts the cam at a first contact force, and in any position other than the neutral position, the leaf spring contacts the cam at a contact force greater than the first contact force.

The moveable socket assembly which includes a housing that has an inner bore. A stud projects out of the inner bore of the housing, and the stud has a shank portion which is at least partially disposed outside of the inner bore. A boot with a flexible body and an adapter is also provided to seal the housing with the stud. The flexible body and the adapter of the boot are made as separate pieces from one another, and the flexible body extends from a first end portion that is sealed with the housing to a second end portion. The adapter is interposed between the second end portion of the flexible body and the shank portion of the stud, and the adapter holds the second end portion in a predetermined location relative to the shank portion.
