摘要： From an optical disc drive, internal static electricity has to be discharged to the outside to prevent breakage of electric components such as laser diodes. A grounding spring has been used to discharge static electricity from a unit mechanism to the enclosure of the optical disc drive but it is necessary to improve the reliability of the drive in consideration of the dimensional accuracy and workability of the spring. Thus the free end of a grounding spring having a cantilever structure is shaped like an arc and an end of the grounding spring has a curved structure. This configuration improves the dimensional accuracy and workability of the spring, so that the performance of the optical disc drive can be more reliable.

摘要： In an optical disc drive, a degradation of traveling performance of an optical pickup under hard acceleration or hard deceleration in a random access operation or the like results in a degradation of recording/reproducing performance. Groove structure is provided between two gears of a guide feed provided in an optical pickup, and the groove forms bending structure. Thus, the engagement state between a screw gear and the gears of the guide feed is stabilized. This makes it possible to prevent tooth jumping and step-out from occurring in the gears during the traveling of the optical pickup, achieving stable traveling. In consequence, the recoding/reproducing performance of the optical disc drive can be improved.

摘要： An electric linear motion actuator includes: a rotary shaft to be driven by an electric motor; a plurality of planetary rollers kept in rolling contact with a cylindrical surface formed on an outer periphery of the rotary shaft; a carrier which retains the planetary rollers such that the planetary rollers are rotatable about axes thereof while revolving around the rotary shaft, and of which axial movement is restricted; and an outer ring member surrounding the planetary rollers and supported so as to be slidable in an axial direction. Helical ribs are formed on an inner periphery of the outer ring member; and circumferential grooves are formed on an outer periphery of each of the planetary rollers so as to be engaged with the helical ribs. A rotation of the rotary shaft is thus converted to a linear motion of the outer ring member.

摘要： An electric brake system is proposed which includes an electric linear motion actuator and can generate the required braking force with high accuracy. A load sensor (30) is provided in a motion converting mechanism of the actuator which converts the rotary motion of a rotary shaft (4) to which the rotation of an electric motor (2) is transmitted to linear motion of an outer ring member (5) as an output member. The load sensor (30) detects the pushing force with which the outer ring member (5) linearly drives a driven member. With this arrangement, if the driven member is a braking member of an electric brake system, it is possible to directly detect the braking force applied by the driven member and thus to accurately generate the required braking force.

摘要： In an electric linear motion actuator for transmitting torque of a rotary shaft (4) to planetary rollers (7) and thus to a linearly driven output member constituted by an outer race member (5), axial movement of a carrier (6) supporting the planetary rollers (7) is restricted, and the outer race member (5) is axially slidably fitted in a radially inner surface of a cylindrical portion (1a) of a housing (1) and is rotationally fixedly coupled to an object to be driven via keys (25) The planetary rollers (7) have their radially inner surfaces rotatably supported, on respective support pins (6c) of the carrier (6), and are radially inwardly biased by radial compression ring springs (21) wound around the support pins (6c) so as to envelop the support pins. The planetary rollers (7) are thus pressed against the radially outer surface of the rotary shaft (4).

摘要： A linear motion actuator includes an outer ring member mounted in a housing, a rotary shaft rotated by a motor, planetary rollers mounted between the outer ring member and the shaft and supported by a carrier rotatable about the shaft. A helical rib is formed on the inner surface of the outer ring member which is engaged in helical grooves formed in outer surfaces of the planetary rollers. When the shaft rotates, the planetary rollers rotate and revolve, thereby axially moving the outer ring member. Uneven axial loads applied to the planetary rollers from the outer ring member are supported by thrust bearings disposed between the planetary rollers and an inner disk of the carrier. Aligning seats are provided between each opposed pair of the planetary rollers and the thrust bearings such that the contact surfaces of the aligning seats shift relative to each other under the uneven axial loads.

摘要： An electric linear motion actuator is proposed which includes planetary rollers mounted between the radially inner surface of an outer ring member and the radially outer surface of a rotary shaft, and a carrier rotatable about the rotary shaft and including radially movable roller shafts rotatably supporting the respective planetary rollers. Elastic rings each having circumferentially separate ends are each wrapped around the roller shafts to radially inwardly bias the roller shafts, thereby bringing the respective planetary rollers into elastic contact with the radially outer surface of the rotary shaft. Each elastic ring is prevented from rotating relative to the roller shafts, thereby preventing one of the roller shafts from being axially aligned with the gap between the circumferential separate ends, causing the elastic ring to be radially compressed and thus making it impossible for the elastic rings to radially bias the roller shafts.
