A follower bearing 1 includes: an inner member 10 including a first body 50 and a flange 52; an outer ring 20; a plurality of rolling elements 40; and a first sealing member 30A including an annular first portion disposed between an outer peripheral surface 52A of the flange 52 and a first surface 22A and at least partially forming a sealing structure between the first portion and the outer ring 20. The first portion has an outer diameter that gradually increases toward a first end surface 52B at an end opposite to a first rolling surface 51A of the flange 52 in an axial direction.

The invention relates to a cam assembly, a linear motion device, a suspension system and a vehicle, the cam assembly comprises a cam and a driving mechanism, the driving mechanism comprises a first actuating piece and a second actuating piece, the first actuating piece is configured to drive the cam to rotate by rotating around a first pivot axis of the first actuating piece, and the second actuating piece is configured to drive the cam to rotate by rotating around a second pivot axis of the second actuating piece. The central axis of the second actuating piece is parallel to and spaced from the first pivot axis, and the second actuating piece can move relative to the cam, so that the cam moves relative to the first actuating piece, and the position of the rotating center line of the cam is changed. According to the technical scheme, the rotating area of the cam can be increased so as to increase the acting stroke of the cam.

The invention discloses a rotation-axial conversion transmission speed change device and application thereof. The rotation-axial conversion transmission speed change device comprises a power source assembly, a driven rotating piece and a plurality of transmission pieces. The driving part is provided with a driving surface, and the driving surface is provided with an axial height profile changing in the circumferential direction, forms rolling or sliding contact with one end of the transmission part and drives the transmission part to move axially; the other end of the transmission part is in meshed contact with the end face teeth or the circumferential teeth of the driven rotating part in the axial movement process, or indirectly pushes the driven rotating part to rotate through a rolling body arranged between the transmission part and the driven rotating part. Through an intermittent transmission mechanism that rotation drives axial displacement and axial displacement pushes rotation output, speed change, quick response and a compact structure are achieved. The invention can be applied to the scenes of transmissions, clutches, overrunning clutch devices, servo braking devices, robot joint modules and the like.

An engine valve actuation system includes a camshaft rotatable in an engine and a composite collar including a mounting sleeve, a guide sleeve, and a bridge connecting the guide sleeve to the mounting sleeve in cantilever fashion. A first valve lifter is interference fit in the mounting sleeve, and a second valve lifter is slide fit in the guide sleeve. First and second lifter bores accommodating the first and second valve lifters are congruent, and the first and second valve lifters can be substantially identical. The composite collar reciprocates with the interference fit first valve lifter, slideably accommodates the slide fit second valve lifter, and restricts rotation of both in service.

An actuation assembly for a reciprocating surgical tool includes a reciprocating shaft extending along a longitudinal axis and a rotating body operably connected to the reciprocating shaft. The rotating body forms opposing guide profiles defining an extension profile and a retraction profile of the reciprocating shaft. A rotation of the rotating body relative to the reciprocating shaft causes the opposing guide profiles to operably engage the reciprocating shaft causing the reciprocating shaft to extend responsive to the extension profile and retract responsive to the retraction profile along the longitudinal axis.

The application discloses a cam mechanism, a cam follower assembly, a cam follower component, a shock absorber, a suspension system and a vehicle, and the cam mechanism comprises a cam body, a cam follower assembly and a lubricating mechanism, the cam body is provided with a guide groove, the cam follower assembly is matched with the guide groove, and the lubricating mechanism is used for lubricating the matched position of the cam body and the cam follower assembly. According to the cam mechanism of the embodiment of the application, the lubricating mechanism can provide the lubricating effect on the matched position between the cam body and the cam follower assembly, so that the relative movement between the cam follower assembly and the cam body is more smooth, and the friction and abrasion between the cam follower assembly and the cam body can be reduced, thereby being beneficial to prolonging the service life of the whole cam mechanism.

A driving mechanism includes a driving member (30), a transmission member (40), and a swinging member (70). The driving member (30) has an output end. The transmission member (40) is connected to the output end of the driving member (30). The transmission member (40) has a driving slot (40b), and the driving slot (40b) extends along a circumferential direction of the transmission member (40). The swinging member (70) is configured to be movably connected to a body of a robot. A part of the swinging member (70) is movably connected in the driving slot (40b), and configured to move along the driving slot (40b) under drive of the transmission member (40) to drive the swinging member (70) to swing.
