摘要： An electric linear motion actuator including: a locking mechanism capable of locking and unlocking the rotation of a rotor shaft (12) of an electric motor (11); wherein the locking mechanism includes: a plurality of locking holes (41) provided in the side surface of one (33) of a plurality of gears constituting a reduction gear mechanism (13) so as to be arranged in the circumferential direction of the one (33) of the plurality of gears; a locking pin (42) configured to be moved forward and backward with respect to the locking holes (41), and brought into engagement with one of the locking holes (41) to lock the gear (33) when the locking pin (42) is moved forward; and a linear solenoid (43) configured to move the locking pin (42) forward and backward. In this electric linear motion actuator, a plunger (49) provided in the linear solenoid (43) and the locking pin (42) are formed as separate parts, and disposed on the same axis such that one of the end surfaces of the linear solenoid (43), and of the locking pin (42), face each other in the axial direction. This prevents the moment load applied by the gear (33) to be locked to the locking pin (42) from acting on the plunger (49), thereby preventing a bobbin (48) slidably supporting the radially inner surface of the plunger (49) from being damaged. Further, the locking pin (42) is made of a non-magnetic material so that the magnetism of the magnetic circuit formed between a coil (47) of the linear solenoid (43) and the plunger (49) can be prevented from leaking through the locking pin (42). This allows the plunger (49) to be reliably attracted and moved by the magnetism when the coil (47) is energized, thereby improving the reliability of the locking operation.

摘要： A linear motion actuator includes a housing (1), an outer ring member (5) axially movably mounted in the housing, and a rotary shaft (10) extending along the axis of the outer ring member (5) and rotated by an electric motor (11). Planetary rollers (21) are rotatably supported by a carrier (14) supported by the rotary shaft (10) so as to be rotatable about the rotary shaft. A helical rib (6) is formed on the radially inner surface of the outer ring member (5) which is engaged in helical grooves (23) formed in the radially outer surfaces of the respective planetary rollers (21), whereby when the rotary shaft (10) rotates, the planetary rollers (21) rotate about their own axes while revolving around the rotary shaft due to frictional contact with the rotary shaft, thereby linearly moving the outer ring member (5) in the axial direction. Axial loads applied to the planetary rollers (21) from the outer ring member (5) at this time are supported by thrust bearings (24) disposed between the respective planetary rollers (21) and an inner disk (14a) of the carrier (14). Aligning seats (27) are provided between each opposed pair of the planetary rollers (21) and the thrust bearings (24) such that the contact surfaces of the aligning seats (27) shift relative to each other when uneven loads are applied to the planetary rollers, thereby making uniform the surface pressure distribution of the thrust bearings (24) in the circumferential direction.

摘要： An electric linear motion actuator is provided of which the planetary rollers can be kept in elastic contact with the radially outer surface of the rotary shaft at all times using inexpensive elastic rings such that the rotation of the rotary shaft is reliably transmitted to the planetary rollers at all times. The planetary rollers (21) are mounted between the radially inner surface of an outer ring member (5) and the radially outer surface of a rotary shaft (10). The actuator further includes a carrier (14) rotatable about the rotary shaft (10) and including as many roller shafts (19) as the planetary rollers (21) which are radially movable and rotatably support the respective planetary rollers (21). Elastic rings (23) each having circumferentially separate ends are each wrapped around the roller shafts (19) to radially inwardly bias the roller shafts (19), thereby bringing the respective planetary rollers (21) into elastic contact with the radially outer surface of the rotary shaft (10). Each elastic ring (23) is prevented from rotating relative to the roller shafts (19), thereby preventing one of the roller shafts (19) from being axially aligned with the gap between the circumferential separate ends, causing the elastic ring (23) to be radially compressed and thus making it impossible for the elastic rings (23) to radially bias the roller shafts (19).
