Publication number: 20210140514Abstract: A circle drive for rotating a blade on a draft frame of a motor grader includes a circle gear mounting the blade, a worm wheel, a torque dividing arrangement, and a single input provided on a first shaft. The torque dividing arrangement includes a set of shafts positioned about the worm wheel, a torque dividing gear set, and a set of worm gears meshed with the worm wheel. The worm wheel is operatively coupled to drive the circle gear. The set of worm gears includes a first worm gear on a first shaft and a second worm gear on a second shaft. The single input is configured to provide a driving torque that drives the set of worm gears such that the set of worm gears divides the driving torque. The driving torque is capable of driving the worm wheel for driving the circle gear and rotating the blade.Type: ApplicationFiled: November 11, 2019Publication date: May 13, 2021Inventors: Alfred S. Smemo, Steven R. Whiteman

Patent number: 10919587Abstract: A suspension system supports a chassis relative to a crawler mechanism including a continuous track. A link is rotatable about an axis extending transversely through a first portion. The first portion includes a projections extending radially inwardly, and peripheral openings defined by spaces between the projections. An axle member secured to the crawler mechanism includes peripheral shafts extending radially outward from the axis and positioned in an associated peripheral opening. Each resilient member is positioned within an associated peripheral opening and engages an associated peripheral shaft, damping movement of the peripheral shaft relative to the link. An auxiliary roller assembly includes a yoke and a plurality of auxiliary rollers coupled to the yoke. The yoke is rotatable relative to the crawler frame about a yoke axis. The auxiliary rollers are aligned along a direction of travel of the track and are configured to engage an inner surface of the track.Type: GrantFiled: May 31, 2019Date of Patent: February 16, 2021Assignee: DEERE & COMPANYInventors: Galen C.

Publication number: 20200309467Abstract: The present disclosure provides a two phase oil cooling system for a work vehicle. The system includes a condenser, an evaporator, a refrigerant path, and a pump. The condenser cools a refrigerant from vapor form to liquid form. The evaporator exchanges heat between a first fluid of the work vehicle and the refrigerant, and heats the refrigerant from liquid form to vapor form. The refrigerant path comprises a first refrigerant path thermally coupling the condenser to the evaporator and a second refrigerant path thermally coupling the evaporator to the condenser. The refrigerant flows through the refrigerant path. The pump is positioned in the first refrigerant path for pumping the refrigerant from the condenser to the evaporator, such that the evaporator is downstream of the pump and the condenser is downstream of the evaporator.Type: ApplicationFiled: March 28, 2019Publication date: October 1, 2020Inventors: STEVEN R.
