Differential case processing
Abstract:The main differential is the driving car parts. Differential role is to transmit power to the axle on both sides at the same time, allowing both sides of the axle rotating at different speeds to meet the both sides of the wheel as far as possible in the form of pure rolling road of no offset, reducing the friction between tire and ground. By the ordinary differential gear, differential case (planetary gear frame), side gears and other parts. The power of the engine drive shaft into the differential, direct-drive planetary drive axle differential case, then the planetary wheel drive left, right, two axle, respectively, drive left and right wheels. This article is to introduce a differential case processing technology and processing needs of special boring machine in the fixture design. First of all parts of the process of analysis needed to understand the processing of surface machining accuracy to hit, to determine the allowance of each machined surface. To develop a reasonable process to meet the processing needs of the program. To ensure the machining accuracy is required datum selection and positioning of parts, and follow certain basic principles, and the positioning error analysis. Processing also involves a variety of extra fixture design. This paper describes the design of special fixture boring, there are fixture positioning, parts and components of the connection, the connection with the machine specific folder and error analysis.
