The invention relates to an expansion sleeve (10), the sleeve being configured to be arranged on an axle (110) to secure the axle in a hole (4), the sleeve comprising: a first and second section (20, 30) with a first and second outer diameter (D11, D2); wherein the first section has a conical shape with a tapering inner wall (22), and an outer wall (24) configured to abut an inner wall of the hole, the second section being configured to axially abut a fastening device (130) arranged at an end of the axle, wherein the second outer diameter is smaller than the first outer diameter, and wherein the second section comprises an inner wall (32) extending with an angle relative the axial direction (A) of the sleeve which is smaller than the angle (β) of the tapering inner wall of the first section.

A drive transmission device of the present disclosure includes a first member and a second member, a drive source, two bracket portions, a shaft portion, a reduction unit having an output portion, and a housing portion. The first member and the second member are coupled to each other so as to be rotatable about a rotation axis. The two bracket portions are provided on the second member and are spaced apart from and opposed to each other. The shaft portion is connected to the first member and positioned between the bracket portions. The output portion is attached to the shaft portion and attached to an opposed surface of a first bracket portion. The housing portion is coupled to the shaft portion so as to be rotatable about the rotation axis, the housing portion being attached to an opposed surface of a second bracket portion.

A replaceable bearing insert may include a bearing surface including a curvature configured to be complementarily contoured to a trunnion ball. The bearing surface may be configured to be in confronting engagement with the trunnion ball. An outer surface opposite the bearing surface may be configured to be received in confronting engagement with an inner surface of an adapter. A first semi-annular flange may extend radially outwardly beyond the outer surface. A second semi-annular flange may extend radially outwardly beyond the outer surface. The first semi-annular flange and the second semi-annular flange may be configured to extend along a first side and a second side of the adapter, respectively, such that the inner surface of the adapter is positioned between the first semi-annular flange and the second semi-annular flange.

A base assembly for a working machine. The base assembly comprising a ground engaging structure, an undercarriage connected to the ground engaging structure, and a connector for connecting the undercarriage to a superstructure that mounts a working arm. A drive arrangement is provided for moving the ground engaging structure to propel, in use, the base assembly and a connected superstructure. The drive arrangement includes a prime mover and a transmission and the drive arrangement is housed within the undercarriage. An electronic control unit (ECU) is provided for controlling the drive arrangement and/or the ground engaging structure.

The invention relates to a bolt connection with a bearing bolt, in particular for a construction machine, in particular for underground engineering and for a swivel lever, in particular for a construction machine, which connects a first component and a second component pivotably to each other, wherein the bearing bolt extends through at least one first bearing eye on the first component and at least one second bearing eye on the second component, and wherein the bearing bolt can be driven, for releasing the connection, on an exit side out of the first bearing eye and the second bearing eye. At the exit side a protective reception is arranged, which is designed to receive and hold the driven-out bearing bolt.

An arm for a construction machine, including an arm top formed by casting, being easily produced with high dimensional accuracy. The arm includes an arm body and an arm top. The arm top is formed of left and right arm top pieces individually formed by casting and joined together. The left and right arm top pieces include first left and right bosses constituting a first connection section, second left and right bosses constituting a second connection portion, and left and right projecting wall portions constituting a connection wall connecting the first and second connection portions to each other, respectively. The left and right arm top pieces are joined together by welding at respective opposing surfaces of the first left and right bosses, those of the second left and right bosses and those of the left and right projecting wall portions, thereby forming the arm top.

Provided is a working machine including first and second members, an angle detection device and a connection pin connected to the first and second members to rotate integrally with the second member relative to the first member. The angle detection device has a marker, an angle sensor and a guard member, which has a main guard portion covering the angle sensor and including an inner opposite surface opposed to an end surface of the projecting end portion and a guard-member-side engagement portion. One of the angle sensor and the marker is disposed on the inner opposite surface, the other disposed on the end surface. The first member has a first-member-side engagement portion engaging with the guard-member-side engagement portion to restrain the main guard portion from relative rotation. The guard member can contact with the connection pin to restrain the guard member from relative displacement to the projecting end portion.

Embodiments of the invention relate generally to earth movement machine components and, more particularly, to a pivot system with adjustable height to actuate a door latch for an excavator bucket.

A boom turret for a debris body. The boom turret includes an inlet defining an inlet axis and configured to couple to a hose. An outlet defining an outlet axis and configured to rotatably couple to the debris body. The inlet axis is substantially orthogonal to the outlet axis and a debris flow path is defined within the boom turret between the inlet and the outlet. A plate is disposed between the inlet and the outlet and has a surface at least partially defining the debris flow path through the boom turret. A nozzle is coupled to the plate and extends into the debris flow path. A pressure vessel is configured to hold a charge of pressurized fluid, and the pressure vessel is coupled in flow communication with the nozzle and selectively releases the charge of pressurized fluid through the nozzle to dislodge accumulated debris within the debris flow path.

A cartridge includes a body, an aperture extending through the body sized to receive a pivot pin, and a spherical bushing disposed within the body. The cartridge also includes a first internal seal disposed axially on one side of the bushing and a second internal seal disposed axially on an opposite side of the bushing. The cartridge also includes an end cap disposed at least partially within the aperture that abuts the bushing and prevents the bushing from moving axially in a first direction within the aperture.
