摘要： A linear motion guide unit includes a U-shaped bed, a U-shaped table turned upside down, a plurality of rolling members in a guide channel defined between the bed and the table, a retainer for retaining the rolling members in position, a pin provided at each end of the retainer and a belt provided at each end of the unit with its one end fixedly attached to the bed, its other end fixedly attached to the table and its intermediate portion passed around the pin. Thus, the retainer is moved only in synchronism with the table or bed and over a half of the distance travelled by the table or bed.

摘要： The present invention provides a finite linear motion rolling guide unit comprising: a track member; and a link mechanism for holding ball rolling members which is arranged between vertically depending track portions of a sliding member which rides over the track member through the ball rolling members so as to be finitely linearly slidable. The link mechanism is simply constructed by two or more link arm members. In the relative reciprocating motion at any speed of the track member and the sliding member, a deviation movement thereof from the normal position of the ball linear moving members is prevented and, at the same time, the smooth and stable linear motion rolling guiding operation of the balls is assured.

摘要： The lubrication insertions system of the present invention inserts lubricating oil into the critical areas of a bearing. The system comprises a delivery element for delivering lubricating oil to a predetermined point relative to the bearing. The bearing, which is rotating, causes the lubricating oil to be slung outward of the spin axis of the bearing. A cage element, having a lip that extends beyond the edge of the bearing, captures the lubricating oil and directs the lubricating oil into the bearing to the outer race of the bearing and to the rolling elements of the bearing, which track the oil to the inner race of the bearing.

摘要： A bearing wherein the size of the rotatable components, i.e. balls or needle rollers, can be maximized while the cage dimensions are minimized, thus aiding overall design for a mechanical device in which the bearing is located. The bearing comprises a cage constructed of flat flexible material, the cage having a generally U-shaped transverse cross-section with a number of rotatable components located between the arms of the generally U-shaped cross-section cage, each component extending partially through aligned apertures in each of said arms. When inserted between two facing helical surfaces and in engagement with both the cage automatically conforms to the pitch of the helical surfaces without the necessity of being pre-shaped to conform thereto.

摘要： A rotary structure adapted to be used as a spindle unit for a miniature motor or miniature rotor or as a tape guide roller for a VTR. In the structure of the rotary mechanism, instead of a conventional expensive radial ball bearing, a groove of a semicircular cross-section is formed in a shaft itself so as to hold balls between this groove and the ball receiving concave surface of an outer race provided around the groove.

摘要： A high performance anti-friction bearing assembly for use in supporting a low torque stabilized platform as, for example, a gun platform mounted on aircraft, a ship or a land vehicle. The bearing assembly comprises three rings of forged alloy steel separated by two axially spaced rings of balls along elements of converging conical surfaces. The balls and their cooperating raceways have a conformity factor of approximately 0.59 and are pre-loaded against these raceways at a normally prevailing contact angle of 35.degree.. The high conformity factor together with various other design features provide a bearing for a stabilized platform operating at high efficiency with minimal torque losses under both simultaneous and non-simultaneous axial, radial and moment load conditions and associated distortio
