About Gearbox's Introduction

The present invention relates to an improved gearbox having both a symmetrical housing and straddle-mounted bearings, to provide a gearbox which is both versatile and moderate in cost.

In the prior art, certain gearbox designs existed which included a relatively expensive housing and/or a housing which required a variety of different internal mount mechanisms for righthand drive and/or lefthand drive, whether clockwise or counter-clockwise.Other gearbox designs of the prior art required several different mounting mechanisms for the bearings depending upon whether the output shafts were disposed to the left or to the right, or both.

In addition, certain of the prior art gearboxes required an extended hub for the input shaft, principally because the output shaft was journaled on bearings held by and disposed near the exterior of the gearbox housing. This larger gearbox was less convenient to use in certain applications.

Additional examples of prior art gearboxes have utilized bearings which were made of metal, and although functioning adequately and with good bearing life, such bearings were of a relatively large cost for the functioning they provided.

In view of the defects, deficiencies and detriments of such prior art gearbox designs, it is a principal object of the gearbox of the present invention to materially overcome these defects, deficiencies and detriments.More particularly, it is an important object of the improved gearbox of the present invention to provide a symmetrical housing which is greater in versatility than prior art asymmetrical gearboxes.

It is a further object of the improved gearbox of the present invention to provide a gearbox having both a symmetrical housing and bearings which are straddle-mounted to reduce the overall size of the gearbox housing.It is also a further object of the improved gearbox of the present invention to provide an improved gearbox having a common bearing mount which includes bearing mount means for journaling each of the shafts required for any given gearbox design.It is a yet further object of the improved gearbox of the present invention to incorporate bearings formed of a plastics and/or composite material for retention of strength and bearing life while reducing cost.

These and other objects of the improved gearbox of the present invention will become apparent to those of ordinary skill in the art upon reviewing the following summary of the invention, brief description of the drawing, detailed description of preferred embodiments, appended drawings and the claims hereof.

The improved gearbox of the present invention includes a symmetrical, split-half housing, which may be preferably formed of die-cast aluminum, or other metal. Such housing has top and bottom portions with input and output shaft openings therein. The input and output shafts are disposed therethrough. The housing has a horizontal plane of symmetry such that the top and bottom portions are essentially interchangeable. The housing also has a transverse plane of symmetry taken longitudinally along and through at least one of the input and/or output shafts.

A common bearing mount is disposed within the housing and holds the bearings thereon for journaling the input and output shafts. Such bearings are held on the common bearing mount and are preferably formed in preferred embodiments of a plastics and/or composite material.

The basic and novel characteristics of the improved apparatus of the present invention will be readily understood from the foregoing disclosure by those skilled in the art. It will become readily apparent that various changes and modifications may be made in the form, construction and arrangement of the improved apparatus of the present invention, which various respective inventions are as set forth hereinabove without departing from the spirit and scope of such inventions. Accordingly, the preferred and alternative embodiments of the present invention set forth hereinabove are not intended to limit such spirit and scope in any way.

These features of the improved gearbox of the present invention have resulted in a gearbox which has a minimum of internal functional parts, which has great versatility, and is made available at moderate cost.
