摘要:
A track bushing for use with a track assembly of a track-type machine includes a generally cylindrical member having ends adapted for mounting in opposing end portions of a track link and a longitudinal bore extending between the ends. The inner surface of the bore defines first and second load bearing portions at each of the ends. Each of the first load bearing portions define a first conical surface tapering radially inward from each of the ends at a first angle, and each of the second load bearing portions define a second conical surface tapering radially inward from each of the first conical surfaces at a second angle. In the bushing's assembled state, the first angle is in the range of 0.09 degrees to 0.18 degrees and the second angle is in the range of -0.01 degrees to 0.01. In the bushing's free state, the first angle is in the range of 0.19 degrees to 0.27 degrees and the second angle is in the range of 0.06 degrees to 0.08 degrees.

A fluid distribution system and method for mobile applications. The system includes a power source, a pump driven by the power source, and a motor driven by the pump. The system also includes a spray head with a fluid inlet passage, a fluid outlet passage, a fluid piston disposed in a chamber for controlled access between the inlet and outlet passages and defining a variable orifice, and a hydraulic cylinder controllably engaged to the orifice. The fluid piston and the hydraulic cylinder are aligned with a common longitudinal axis, and the inlet passage is offset from the axis in a direction opposed to the location of the outlet passage.

A mobile fluid delivery machine for delivering fluid to a site has a tank storing fluid, and at least one spray head configured to spray the stored fluid onto the site. In addition, the machine has a communication device configured to receive fluid delivery mission instructions from a site computing system, the mission instructions identifying a sequence of path segments on the site and corresponding fluid delivery amounts allocated to the path segments, and a location device configured to determine the location of the machine on the site. Th machine may also have a fluid delivery system configured to determine whether the location of the fluid delivery machine corresponds to a path segment of the sequence, and when it is determined that the location of the machine corresponds to a path segment in the sequence, to identify the fluid delivery amount allocated to that path segment based on the mission instructions.

A systems and methods for delivering fluid to a site using a mobile fluid delivery machine are disclosed. The method includes determining a location of the mobile fluid delivery machine on the site, and determining a fluid delivery rate based on the location of the mobile fluid delivery machine using information related to the site. The method further includes delivering the fluid to a surface of the site at the location of the mobile fluid delivery machine, at the determined fluid delivery rate.
摘要:
A method of hardening a work piece having (i) an outer surface, (ii) an inner surface which defines a passageway extending through the work piece, and (iii) an end. The method includes the steps of (A) advancing the work piece through a first induction coil such that a first hardened area is formed on the work piece, (B) advancing a second induction coil into the passageway of the work piece such that a second hardened area is formed on the work piece, and (C) positioning a third induction coil adjacent to the end of the work piece such that a third hardened area is formed on the work piece. The positioning the third induction coil step is performed after (i) the advancing the work piece through the first induction coil step and (ii) the advancing a second induction coil into the passageway step.

A track seal assembly (174) adapted to seal a track joint (172) includes a track link and a ceramic seal member (186). The track seal further includes an elastomeric member (176) positioned between the track link and the ceramic seal member (186). The track seal (174) further includes a bushing (184) having a ceramic end face (187). The end face (87) of the bushing defines a ceramic bushing face (187) that interfaces with the ceramic seal member (186) so as to form a seal interface.

A track bushing for an endless track of a track-type machine includes a cylindrical tubular shape having a first end and a second end and a longitudinal axis. The track bushing further includes a first end bearing surface that is adjacent to the first end and a second end bearing surface that is adjacent to the second end. A circumferential groove is formed in at least one of the first end bearing surface and the second end bearing surface. The circumferential groove has a depth along the longitudinal axis. An abrasion and corrosion resistant material is arc welded within the circumferential groove to the bushing at a weld joint.

Systems and methods for controlling fluid delivery on a site using at least one fluid delivery machine are disclosed. An exemplary such method includes identifying at least one path on the site based on map information associated with the site, calculating a fluid delivery requirement of the at least one path based on environmental information associated with the site, and dispatching a fluid delivery machine on a mission to treat the at least one path with fluid based on the fluid delivery requirement.
