Abstract
An improved lock plate and retaining ring mounting arrangement for securing a gear on a vehicle rotating shaft by a threaded hex-head fastener. The plate has a generally rectangular central aperture with transversely opposed internal side edges and longitudinally opposed arcuate end edges. The plate has a pair of arcuate opposed concentric slots sized to adjustably receive an associated web bolt for threaded reception in a web bore thereby locking the shaft fastener in its tightened position. A one-piece retaining ring, concentrically positioned so as to overly the plate, comprises opposed semicircular bands interconnecting a pair of diametrically opposed discs provided with a bolt hole adapted aligned with both an associated plate slot and a web bore. Each disc is formed with a plurality of radially disposed tabs whereby at least one of the tabs is in substantial registration with a side face of an associated web bolt head. The one tab is bendable from a planar position to a locking position in substantial flatwise contact with its registered web bolt side face thereby locking the bolt in its tightened position.
