Patent number: 6219927Abstract: A differential gear housing includes grooves into which retaining rings are fitted which engage on races of tapered roller bearings. The width of the securing rings is determined in accordance with the desired tooth flank clearance between a ring gear and a bevel drive pinion and with a desired prestress in the tapered roller bearings. Preliminary to selecting the retaining rings, devices are used which engage with a tensioning bush in the grooves and have a pressure member movable axially inside the tensioning bush and supported on the respective tapered roller bearing race. The pressure member is then suitably moved in relation to the tensioning bush to a position where the desired prestress and tooth flank clearance have been reached. The desired retaining ring axial width can then be read off from the device followed by selection and insertion of the desired retaining rings.Type: GrantFiled: June 24, 1999Date of Patent: April 24, 2001Assignee: Bayerische Motoren Werke AktiengesellschaftInventor: Fritz Westermaier

Patent number: 6219930Abstract: A method of use and apparatus for estimating repair cost, particularly applicable to cost estimation of interspaced defect damaged vehicle surfaces. The method of use of the present invention provides that a defect count be made for a predetermined representative area; that a determination of relative severity be made with respect to at least one defect within the representative area; and that the repair estimate is then based upon the defect count information and defect severity. A set of physical templates may be provided, with a first template allowing the calculation of the number of dents per surface area, and a second template for grading, comparing, or otherwise determining the size or severity of the individual dents. Additionally, the defect count data and defect severity data may be determined with an electronic scanning means. Various formulae may be employed (manually or electronically) for calculating the cost estimate to repair the damaged surface.Type: GrantFiled: December 18, 1998Date of Patent: April 24, 2001Inventor: Mark Reid
