Abstract
A gear reducer housing includes mating front and rear shells, each formed with supports for bearings and rotating assemblies. The supports are located along a centerline of the housing shells and at two offset mirror image locations on either side of the centerline. The shell is at least partially surrounded by a peripheral flange for securing the housing shells to one another. Fastener apertures in each flange are formed to provide tolerance in the location of attachment fasteners. The flange includes fixturing pads allowing each shell to be fixtured once for a range of machining operations. Ports for lubricant permit the housing to be mounted in several angular positions.

A housing for a gear reducer, the housing comprising:
- first and second identical housing halves, each housing half including an interior portion for receiving a plurality of bearing sets and rotating assemblies, the interior portion being surrounded by a rear wall portion and a peripheral wall, the rear wall of each housing half including a first and second bearing support structures disposed along a centerline of the housing half, and third and fourth bearing support structures disposed at mirror-image locations offset from the centerline, the first and second housing halves being configured to be secured to one another to enclose an interior volume, whereby when the housing halves are secured to one another the first support structures are coaxial, the second support structures are coaxial, the third bearing support structure of the first housing half is coaxial with the fourth bearing support structure of the second housing half, and the fourth bearing support structure of the first housing half is coaxial with the third bearing support structure of the second housing half.
A housing component for a gear reducer, the housing component comprising:
- a rear wall portion including a first and second bearing support structures disposed along a centerline of the housing component, and third and fourth bearing support structures disposed at mirror-image locations offset from the centerline each support structure being configured to support a bearing set;
- a peripheral wall portion integral with the rear wall portion and surrounding the rear wall portion to form an interior portion for receiving a plurality of bearing sets and intermeshing rotating assemblies.
A housing for a gear reducer comprising:
- a left housing portion;
- and
- a right housing portion configured for assembly with the left housing portion to define an inner cavity therebetween;
- the left and right housing portions each including a first shaft support along a central axis thereof, a second shaft support along the central axis spaced from the first shaft support by a distance DA, and third and fourth shaft supports disposed at mirror-image locations on either side of the central axis, the first shaft support being spaced from the third and fourth shaft supports by a distance DB, and the second shaft support being spaced from the third and fourth shaft supports by a distance DC, the distances DA and DC being greater than the distance DB.
A housing for a gear reducer, the housing comprising:
- first and second housing shells having longitudinal centerlines and configured to be secured to one another for supporting a plurality of intermeshing rotating assemblies;
- a peripheral flange at least partially surrounding each housing shell, each peripheral flange including a plurality of apertures for receiving fasteners for securing the housing shells to one another, the apertures are located at mirror image locations with respect to the centerline.
