Abstract
Abstract A replaceable shim is provided for a planetary gear arrangement of the type having planetary gears each of which is rotatably mounted to a frame by a shaft. The shim includes an elongated flat body having a generally U-shaped recess at one end and which is adapted to be inserted in between the planetary gear and the frame so that the shaft is positioned within the U-shaped recess. The opposite end of the shim is then pivotal to a position in which the opposite end abuts against a portion of the frame thus locking the shaft in the U-shaped recess on the shim body. A bendable locking tab is then bent to a position in which the bending tab abuts against a second surface on the frame and prevents further pivotting of the shim. In doing so, the bending tab locks the shim to the frame with the planetary gear shaft positioned within the shim recess.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
159 words
For use in conjunction with a member rotatably mounted to a shaft, said shaft being secured to a frame, a shim comprising: a flat body having a recess, said body being insertable between said frame and said member so that said shaft is positioned within said recess, means for locking said body to said frame so that said shaft remains in said recess comprising a surface on said body adapted to abut against a surface on said frame, said body surface being spaced from and facing substantially away from said recess, a tab on said body, said tab being bendable between an unlocked position and a locked position, wherein in said unlocked position said body is pivotal about said recess to a position in which said body surface abuts against said frame surface, and wherein in said locked position, said tab abuts against a second surface on said frame and prevents further pivotting of said body about said recess.
Claim 2
Dependent Claim
