Abstract
Abstract In a paper machine the couch roll gear drive is provided with eccentric adjustment to one of the gear support bearings, thereby permitting the setting and adjustment of the gear under working conditions, to provide satisfactory gear face contact. A tapered housing interface fitted with a hydraulic jack-off provision ensures tight fitting of the bearing with its support housing, while permitting ready access for adjustment and lock-up, at very low cost.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
105 words
In a paper machine having a first gear, a second gear rotatably mounted in meshing relation therewith, including bearing means supporting the second gear for rotation therebetween, the improvement comprising a pair of complementary eccentric rings in supporting relation with a said bearing to permit orbital repositioning of said bearing by relative rotation of one ring relative to the other, said eccentric rings having an axially tapering, separable interface therebetween, to provide a tight fit of said bearing in repositionable relation in said housing, and hydraulic jacking means for connection with a fluid pressure source, in use, for freeing said rings off said tapering interface.
Claim 2
Dependent Claim
105 words
In a paper machine having a first gear, a second gear rotatably mounted in meshing relation therewith, including bearing means supporting the second gear for rotation therebetween, the improvement comprising a pair of complementary eccentric rings in supporting relation with a said bearing to permit orbital repositioning of said bearing by relative rotation of one ring relative to the other, said eccentric rings having an axially tapering, separable interface therebetween, to provide a tight fit of said bearing in repositionable relation in said housing, and hydraulic jacking means for connection with a fluid pressure source, in use, for freeing said rings off said tapering interface.
Claim 3
Dependent Claim
36 words
The machine as claimed in claim 1, said jacking means including a groove recess with a threaded entry, for connection in use with lubrication means to force lubricant between said rings in axial freeing relation therebetween.
Claim 4
Dependent Claim
26 words
The machine as claimed in, claim 1 wherein said first gear is connected in driving relation with a couch roll having suction applying means located therein.
