Abstract

A roller conveyor system is disclosed having a frame with a pair of spaced apart rails and at least one roller assembly having an elongated shaft. A first bearing assembly is secured to one rail while a second bearing assembly is secured to the other rail so that the bearing assemblies are aligned with each other and each bearing assembly includes an inner and outer race. The elongated roller shaft extends through the inner races of the bearing assemblies so that a flat formed on the shaft is radially aligned with the inner race of one of the bearing assemblies. A threaded fastener is then threadably secured to the bearing inner race and has one end adapted to abut against the shaft flat. With the fastener in abutment with the shaft flat, the other end of the fastener is substantially flush with an outer surface of the bearing race. An annular collar is then positioned over the outer surface of the bearing inner race and this collar has an inner diameter substantially the same as the outer diameter of the bearing inner race to thus hold the fastener in abutment with the shaft flat. At least one roller is then secured to an intermediate point of the shaft.

Claims

1. A roller conveyor system comprising:

a frame having a pair of spaced apart rails,

at least one roller assembly, said roller assembly having an elongated shaft,

a pair of bearing assemblies, one bearing assembly being mounted to each rail so that said bearing assemblies are aligned with each other, each bearing assembly having an inner race and an outer race,

said elongated shaft extending through said inner races of said bearing assemblies, said shaft having a flat which is radially aligned with said inner race,

a threaded fastener threadably secured to said inner race, said fastener having one end adapted to abut against said shaft flat, said fastener being dimensioned so that, with said one end of said fastener in abutment with said shaft flat, the other end of said fastener is substantially flush with an outer surface of said bearing inner race,

a lock ring positioned over said outer surface of said bearing inner race, said ring having an inner diameter substantially the same as said outer surface of said bearing inner race to thereby hold said fastener in abutment with said shaft flat,

a roller, and

means for attaching said roller to an intermediate point of said shaft.

2. The invention as defined in claim 1 wherein said roller attaching means comprises means for axially adjustably attaching said roller to said shaft.

3. The invention as defined in claim 2 wherein said adjustable attaching means comprises a pair of split rings axially slidably mounted to said shaft, one split ring being positioned on each axial end of said roller, and means for selectively compressibly securing said split rings to said shaft at an axially adjusted position.

4. The invention as defined in claim 3 wherein said compressible securing means comprises a threaded fastener slidably extending through a first portion of said split ring and threadably engaging a second portion of said split ring so that, upon tightening said fastener, said portions of said split ring are drawn together.
