Abstract
Abstract TITLE OF THE INVENTION: Slip Friction Roller Drive INVENTOR: George Rae ASSIGNEE: Rexnord Inc., a Wisconsin corporation ABSTRACT OF THE DISCLOSURE: A slip friction drive for powered roller conveyor apparatus which minimizes coupling of forces between the driving engagement and the bearing surfaces and additionally provides an adjusting means for compensating for the varying frictional forces caused by changing loads.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
257 words
A roller conveyor apparatus comprising: (a) a plurality of hollow, cylindrical rollers mounted for rotary movement about stationary axles fixedly secured to spaced, side-support frames, each of said rollers having a rotary bearing assembly at one end thereof; (b) a driving means for rotating said plurality of rollers; and (c) a slip friction assembly having associated with each said stationary axle: i. an inner bearing member secured to said stationary axle within the other end of its respective said roller, ii. a driven member having a disc portion adapted to engage the driving means and a cylindrical hub extension positioned within said other end of its respective said roller and having inner and outer bearing surfaces, said inner bearing surface ad-apted to rotate on said inner bearing member, and iii. an outer bearing member having a flange portion and a sleeve portion, said sleeve portion exten-ding into said other end in continuous juxta-position with and secured to the inner side of its respective said roller, said sleeve portion having an inner diameter substantially identical to the outer diameter of the outer bearing surface of said driven member and providing a surface against which said outer surface of said hub extension may engage, said flange portion posi-tioned in an abutting relation with the mouth of said other end of its respective said roller and adjacent said disc portion of said driven member, such that the engagement of said disc portion with the driving means is substantially co-planar with the interface of said disc portion with said flange portion.
Claim 2
Dependent Claim
257 words
A roller conveyor apparatus comprising: (a) a plurality of hollow, cylindrical rollers mounted for rotary movement about stationary axles fixedly secured to spaced, side-support frames, each of said rollers having a rotary bearing assembly at one end thereof; (b) a driving means for rotating said plurality of rollers; and (c) a slip friction assembly having associated with each said stationary axle: i. an inner bearing member secured to said stationary axle within the other end of its respective said roller, ii. a driven member having a disc portion adapted to engage the driving means and a cylindrical hub extension positioned within said other end of its respective said roller and having inner and outer bearing surfaces, said inner bearing surface ad-apted to rotate on said inner bearing member, and iii. an outer bearing member having a flange portion and a sleeve portion, said sleeve portion exten-ding into said other end in continuous juxta-position with and secured to the inner side of its respective said roller, said sleeve portion having an inner diameter substantially identical to the outer diameter of the outer bearing surface of said driven member and providing a surface against which said outer surface of said hub extension may engage, said flange portion posi-tioned in an abutting relation with the mouth of said other end of its respective said roller and adjacent said disc portion of said driven member, such that the engagement of said disc portion with the driving means is substantially co-planar with the interface of said disc portion with said flange portion.
Claim 3
Dependent Claim
51 words
The apparatus as claimed in claim 1 in which the driven member is a sprocket and the driving means is a chain, the teeth of said sprocket being formed on the outer periphery of said disc and being substantially co planar with the inter-face of the sprocket disc with the flange.
Claim 4
Dependent Claim
21 words
The apparatus as claimed in claim 1 or 2 including an adjustable resilient means for biasing said disc toward said flange.
Claim 5
Dependent Claim
62 words
The apparatus as claimed in claim 1 or 2 including an adjustable resilient means for biasing said disc toward said flange, and in which said resilient means includes a helical spring about said axle, one end of which is associated with said disc, and an adjustable means associated with the other end of the spring for selectively compressing or releasing said spring.
Claim 6
Dependent Claim
166 words
The apparatus as claimed in claim 1 or 2 including an adjustable resilient means for biasing said disc toward said flange, and in which said resilient means includes a helical spring about said axle, one end of which is associated with said disc, and an adjustable means associated with the other end of the spring for selectively compressing or releasing said spring and said bearing member is keyed to said axle against rotational movement and is free to slide along said axle, said inner bearing member having a head in the form of a flange disc with a diameter greater than the inner diameter of said cylindrical hub and additionally positioned between said hub and helical spring, said helical spring abutting said flange disc whereby said flange disc selectively presses against and releases said hub in response to movement of said adjusting means to cause respectively greater and lesser frictional forces to occur between said driven member and said flange portion of the outer bearing member.
