The invention relates to a linking device for coupling working equipment, such as a head for harvesting trees, to the end of a crane boom on a working machine, said end comprising crane ears, wherein the linking device comprises a linking device body that supports a first rotation shaft defining a first rotation axis and a second rotation shaft defining a second rotation axis that runs substantially transverse to the first rotation axis, wherein the linking device is intended to be suspended by the first rotation shaft between the crane ears for free rotation of the linking device around the first rotation axis on the crane boom, wherein the linking device comprises first braking means for braking the rotational movement of the linking device around the first rotation axis, wherein the first braking means are arranged to move at least one of the crane ears towards the other to clamp the linking device body between the crane ears.

A rotationally compliant bearing roller assembly having a roller, at least one bearing member operably coupled to a base configured to support rotational movement about a rotational axis; and a rotary compliant joint interconnecting the at least one bearing member to the roller. The rotary compliant joint having a first compliance in a rotational direction about the rotational axis to permit movement of the roller in the rotational direction relative to the at least one bearing member, such that the first compliance being greater than a friction induced compliance of the at least one bearing member in the rotational direction. The compliant joint having a second compliance in a direction orthogonal to the rotational direction, such that the second compliance being less than the first compliance.

The present disclosure relates to a carriage lift assembly including a mast member, a top and bottom bearing assembly, one or more belt members, one or more belt tensioner assemblies, and one or more carriage assemblies. Each belt tensioner assembly defines a first clamping block and a second clamping block for securing a first and a second end, respectively, of a belt member to provide initial tension, and a pair of bolt members adjusted to move a slidable plate member upon which the second block is coupled to provide final tension. Each carriage assembly is removably attached to a corresponding belt tensioner assembly, and defines a center plate and two side plates. Each side plate defines at least a removable set of guiding wheels and a first set of guiding members.

A cradle bearing for supporting a swashplate of a variable hydraulic axial piston. The cradle bearing is of an angular ball bearing type or includes, with respect to the bearing axis, a tapered inner race and/or a tapered outer race. A swashplate for a variable hydraulic axial piston unit including a first and a second cradle bearing zone spaced to each other in axial direction of a swashplate tilt axis, suitable for supporting the swashplate in a housing of a variable hydraulic axial piston unit, wherein the first cradle bearing zone is inclined with respect to the swashplate tilt axis. A variable hydraulic axial piston unit of the swashplate type including a swashplate which is supported rotatable in the housing of the variable hydraulic axial piston unit at a first bearing zone by a tapered bearing and at a second bearing zone by regular cylindrical cradle bearing or a journal bearing whose axis is aligned with the swashplate tilt axis.

A telescopic side arm for a refuse vehicle has an inner and outer boom. A mounting assembly secures the outer boom with a refuse vehicle. A plurality of bearing pads is positioned between the inner and outer booms to provide smooth movement between the inner and outer booms. A plurality of shims is associated with the bearing pads to assure a tight fit between the inner and outer booms.

The present disclosure relates to a ball spline device, an automated guided vehicle and a stereoscopic warehouse system. The ball spline device includes: a spline shaft, an outer side wall of which is provided with a raceway groove extending along an axial direction, the raceway groove includes a first groove section and a second groove section communicated along the axial direction, a width of the second groove section being greater than the width of the first groove section; a spline nut coaxially, sleeved outside the spline shaft; and a first rolling body, movably disposed in the raceway groove along the axial direction to achieve relative movement of the spline nut and the spline shaft. When the spline nut is in a first position, the first rolling body is in the first groove section, and cooperates with the first groove section in a constrained manner to cause synchronous rotation of the spline nut and the spline shaft; and when the spline nut is in a second position, the first rolling body is in the second groove section, so that there is a predetermined gap in a circumferential direction between the spline shaft and the spline nut.

A telescopic side arm for a refuse vehicle has an inner and outer boom. A mounting assembly secures the outer boom with a refuse vehicle. A plurality of bearing pads is positioned between the inner and outer booms to provide smooth movement between the inner and outer booms. A plurality of shims is associated with the bearing pads to assure a tight fit between the inner and outer booms.

A gripper includes at least one first gripper finger adjustably mounted to a gripper main body by a gripping finger mount, at least one second gripper finger cooperating with the first gripper finger, and a motor-drivable transmission configured to adjust the at least one first gripper finger relative to the gripper main body and the at least one second gripper finger such that a clamping force is generated, whereby an article can be held in a clamped manner by the gripper. The transmission includes a first transmission member connected to the first gripper finger, and a second transmission member mounted on the gripper main body by a transmission-member bearing arrangement having a first transmission member bearing configured to absorb the transmission-bearing reaction force that acts in a direction of the clamping force. The transmission-member bearing arrangement includes a sensor configured to sense the transmission-bearing reaction force.

A sliding component includes at least one of a pair of sliding members and provided with: a group of recessed portions including a plurality of recessed portions formed in a sliding surface of the sliding member; and a plurality of hollow portions formed inside the sliding member and out of alignment with the recessed portions in a thickness direction of the sliding member.
