CLEARANCE ADJUSTING MEMBER
To provide a clearance adjusting member that allows for easy attaching and detaching works and has no risk of falling off from a pin. A clearance adjusting member, in a pin coupling structure in which a first member and a second member are coupled freely to be rotated in relation to each other by a cylindrical pin, for adjusting an axial clearance between the first member and the second member, the clearance adjusting member comprises a shim in a U-shape or C-shape attached to the pin in the axial clearance, and a restricting means for restricting the shim so as to be freely releasable. A restricted piece protruding radially outward is formed on an outer circumferential edge of the shim. The restricting means includes a pair of restricting pieces spacedly arranged circumferentially on the radially outer side of the pin. One-side slanting piece extending by slanting to the direction of axial one-side towards a circumferential one-side is provided at a circumferential one-side end portion of one restricting piece. Another-side slanting piece extending by slanting to the direction of an axial one-side towards a circumferential another-side is provided at the circumferential another-side end portion of the restricting piece of another side. When the shim is inserted towards the axial clearance, the restricted piece pushes and rides over while elastically deforming the one-side slanting piece towards the circumferential one-side, or the restricted piece pushes and rides over while elastically deforming the another-side slanting piece towards the circumferential another-side, and thereby the restricted piece is positioned between the pair of restricting pieces and the shim is attached to the pin.
CONSTRUCTION MACHINE
This construction machine includes a lower traveling body; an upper swiveling body; and a rotary coupling member that swivels, together with the upper swiveling body, with respect to the lower traveling body. The rotary coupling member has a swivel joint; a rotary joint that includes a slip ring; a cable; a coupling part; and a detent part that is fixed to the body of the swivel joint and that restricts the rotation of a terminal part of the slip ring.
SWIVEL JOINT FOR CONSTRUCTION MACHINE
A swivel joint for a construction machine can detect a slewing angle of an upper slewing body and has a high maintainability. The swivel joint includes a body, a stem, a lower cover, and a sensor unit. The sensor unit includes: a rotation angle sensor fixedly attached to an upper end of the stem; and a rod having a distal end provided with a detection target to be detected by the rotation angle sensor and a proximal end fastened to the lower cover. The stem is formed with: a rod insertion hole for receiving the rod to be inserted therethrough; and a stem-side drain oil passage for allowing a drain oil to pass therethrough.
Hinge assembly for a work vehicle door
A hinge assembly for a work vehicle door includes a hinge having a body and a first protrusion. The first protrusion is configured to extend through a first opening in a panel of the work vehicle door, and the first protrusion has a first engagement feature. The hinge assembly also includes a handle having a first corresponding engagement feature configured to engaged the first engagement feature of the first protrusion while the handle is in an engaged position to couple the panel to the hinge. One of the hinge or the handle has a second protrusion, and the other of the hinge or the handle has a recess configured to receive the second protrusion. The second protrusion is configured to extend through a second opening in the panel of the work vehicle door, and the handle is configured to rotate about the second protrusion to the engaged position.
Automatic Lubrication System for Kinematic Linkage
A mechanical machine can include one or more kinematic linkages having kinematic joints that movably couple first and second rigid links and can include an automatic lubrication system to lubricate the kinematic joints. In an aspect, the automatic lubrication system is configured to monitor operational aspects of the machine such as machine operational data and geometric position and to dynamically determine timing and/or quantity of lubricant to direct and introduce to the kinematic joints.
PIVOTING PINNED CONNECTION FOR A ROPE SHOVEL BUCKET
A pivoting connection between a bucket and a padlock of a rope shovel, a pin assembly, and a rope shovel are disclosed. A pivoting connection includes a pin having a pin axis and extending through a bucket lug of the bucket and a pair of padlock lugs of the padlock; a flag having a pin end and a mounting end; a locking coupling coaxial with the pin axis and located in the pin end of the flag, wherein the locking coupling selectively couples the flag to the pin; and a slotted flag mount attached to the bucket including a vertical slot and a horizontal slot parallel to the pin axis; wherein the mounting end of the flag is received by the slotted flag mount such that the pin is constrained from rotating with respect to the bucket and from translating along the pin axis.
JOINT ELEMENT PROVIDED WITH SWING DAMPENER BRAKE, JOINT ASSEMBLY COMPRISING THE JOINT ELEMENT, AND MACHINE COMPRISING THE JOINT ASSEMBLY
A joint element provided with a swing dampener element and comprising a first joint part, a second joint part, and a swing dampener brake. The second joint part comprises a second end part which is detachably fixed to a first end part of the second joint part by a joint part coupling which is adapted to allow the second end part to be moved in an axial direction to a detached position in relation to the first end part, the detached position allowing replacement of active components of the swing dampener brake while the first end part remains bearing-mounted to the first joint part, the active components of the swing dampener brake comprising at least one first brake disc member and at least one second brake disc member.
STORAGE ASSEMBLY FOR BATTERY ENERGIZING SWITCHES OF ELECTRIC MACHINES
A storage assembly for switches couplable to batteries of an electric machine to energize the batteries. The storage assembly includes a container defining a cavity to store the switches, a lid movable between a closed state and an open state with respect to the container to respectively close and open the cavity, and a lock out tag out (LOTO) device. The container is configured to be grasped between a pair of arms of a handrail that swings with respect to a walkway platform of a power compartment of the electric machine. The LOTO device is interchangeable with the switches to selectively be received in the cavity in place of the switches when the switches are coupled to the batteries, and be coupled to the batteries in place of the switches to lock out and keep the batteries from energizing when the switches are received in the cavity.
Floor mat and working machine
A floor mat arranged in a working machine includes a floor portion, a wall portion arranged on a circumferential portion of the floor portion, and an opening portion arranged on a part of a connecting portion of the wall portion, the connecting portion connecting to the floor portion. The floor mat includes a mat main body arranged on the floor portion, a covering portion configured to cover the opening portion, and an connecting portion configured to connect the covering portion flexibly to a circumferential portion of the mat main body.
WORKING MACHINE
A working machine includes a rear machine body on which an operator's seat is mounted, a front machine body to which a working tool is attached, a center shaft having a first axis extending in a fore-and-aft direction, a first supporting part supporting the center shaft rotatably relative to the rear machine body around the first axis, a coupling shaft having a second axis extending in a vertical direction and connected to the front machine body, and a second supporting part supporting the center shaft rotatably relative to the coupling shaft relative to the second axis. The first supporting part includes a first spherical plain bearing, and the first spherical plain bearing includes a first inner wheel including a convex curved sliding surface and provided on an outer circumferential surface of the center shaft, and a first outer wheel including a concave curved sliding surface and provided on the rear machine body.
