Filed:

Apr 2, 1998

Appl. No.:

9/053757

Inventors:

Craig L. Snyder - Glen Gardner NJ
Thomas A. Roth - Lerna IL
Thomas Thomason - Charleston IL
Randy Webb - Charleston IL
Jerry F. Rau - Richardson TX

Assignee:

Blaw-Knox Construction Equipment Corporation - Mattoon IL

International Classification:

B62D 5500

US Classification:

305199

Abstract:

A paving machine is driven by track assemblies utilizing continuous rubber belts driven by drive wheels. Each drive wheel is driven by a planetary gear assembly. Each drive wheel is formed from a pair of annular ring members rigidly connected together and spaced apart to provide a passage for directing debris falling from a rotating drive wheel away from the planetary gear, to minimize damage to the planetary gear assembly.

Abstract:

A paving machine that is driven by track assemblies utilizing continuous rubber belts uses a motor and planetary gear reduction combination on each drive wheel to drive each belt. Each planetary gear includes a planetary joint connection between a rotating and a non-rotating portion, with an elastomeric seal therein to retain lubricating fluid in the planetary housing. Each drive wheel is formed from a pair of annular ring members rigidly connected together and spaced apart to provide a passage for directing debris falling from a rotating drive wheel away from the planetary joint, to minimize damage to the seal.
