Description
An excavator undercarriage frame is made to reduce the amount of machining necessary for supporting a swing bearing and ring gear on which an upper swing platform including the cab and operator's platform are mounted. The frame is made in two separate frame sections (54, 56) having top plates (60, 76) and formed peripheral skirts (64, 66, 68, 82, 84, 86) that nest together to form a planar support on which the base ring of a swing bearing and ring gear are mounted. The frame section plates are thin enough so that they will flex to conform to the base ring of the swing bearing, so it is not necessary to provide a machined surface for the swing bearing. The frame sections are welded together only around the peripheral edges and skirts, so that the distortion in the plates is substantially eliminated. The plates can be then bolted or secured directly to the bearing base ring, preferably using a clamp ring on the bottom of the frame plates and will provide an adequate support with the two plate thicknesses, and will be true and square without machining.
Features
A self-propelled power excavator or power shovel illustrated generally at 10 has an undercarriage 12 comprising a lower frame and drive assembly and an upper rotatable platform assembly 14 which supports a pivotally mounted two section boom 16 with a bucket 18 at the outer end thereof. The boom sections are operated with hydraulic actuators shown generally at 20 for moving the boom sections about horizontal pivots. The bucket 18 is also operated with a hydraulic cylinder 21. An operator's cab area 22 moves with the upper rotatable platform assembly 14, and includes a housing for an engine 24 to provide power. The platform assembly 14 is mounted to the undercarriage 12 through a swing bearing 26. The undercarriage 12 supports ground engaging tracks 28 that would be driven from a suitable drive arrangement such as hydraulic motors operated from a pump driven by the engine 24.
Application
The undercarriage center frame assembly 30 can support a backfill blade 42, which is mounted onto support arms 44 that attach to brackets 46 that, as will be explained, are welded onto the center frame assembly 30 during assembly. The blade 42 can be raised and lowered relative to the pivots between the arms 44 and the brackets 46 through the use of a hydraulic actuator shown at 48 which has a base end attached to the blade 42, and a rod end attached to a bracket 50 that also is mounted on the center frame assembly 30.
