Excavating apparatus employing swivel adapter with gear bearings having gears with divergent thickness

Abstract

An apparatus for swiveling an implement, such as a bucket, relative to a device, such as an excavator boom, includes a rotary union and a bearing disc mounted in a housing. The bearing disc rotates relative to the housing so that the implement can be rotated relative to the device. A gear or geared bearing assembly is located between the bearing disc and top and bottom housing portions for bearing loads transverse to the axis about which the implement is rotated relative to the device. The rotary union has fluid passages extending from the top to the bottom of a central shaft, which is affixed to the bearing disc, and the shaft and disc can comprise a one piece combination rotary union and bearing disc.

Description

CROSS REFERENCE TO PRIOR CO-PENDING APPLICATIONS[0001]This application is a Continuation-in-part of co-pending U.S. patent application Ser. No. 13 / 530,324 filed Jun. 22, 2012, which also claims the benefit of previously filed, co-pending U.S. Provisional Patent Application 61 / 571,168 filed Jun. 22, 2011.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]This invention relates to a swivel adapter mount that can be used between a device and implement, such as with excavating equipment, such as a backhoe or excavator. A bucket of other implement can then be moved to positions that would not be possible with a conventional backhoe or similar device. This invention is also related to bearing assemblies that will operate in such an environment with a relatively long service life.[0004]2. Description of the Prior Art[0005]Conventional backhoes and crawler type excavators are not suited for digging ditches with sloping sides. These types of conventional excavating equipment do ...

AI Technical Summary

Benefits of technology

This patent describes a swivel apparatus that can be used with excavators or wheeled backhoes. This device allows for more efficient use of excavating tools on a worksite and improves safety by preforming operations that might otherwise require workers to perform in a ditch. The swivel apparatus allows for additional motion and range of motion, allowing a single excavating device to perform multiple tasks. This means that an operator can handle multiple tasks with a single tool and can even level bedding stone and perform other tasks. The swivel apparatus can be used with heavy-duty equipment and provides precise control and durability. Overall, this technology improves the performance and efficiency of excavators and reduces the need for specialty equipment.

Problems solved by technology

Conventional backhoes and crawler type excavators are not suited for digging ditches with sloping sides.

These types of conventional excavating equipment do not have the ability to tilt or swivel a bucket or claw so that a slope can be graded.

However, these devices have not proven to be effective.

In some cases they require a large number of component parts and are therefore costly both to manufacture and to repair.

Others have not proven to be sturdy enough for use in the field.

However, none of these approaches is believed to be as versatile and reliable as the swivel adapter mount of the instant invention.
