摘要:差速器是驅(qū)動(dòng)轎的主件。差速器的作用就是在向兩邊半軸傳遞動(dòng)力的同時(shí),允許兩邊半軸以不同的轉(zhuǎn)速旋轉(zhuǎn),滿(mǎn)足兩邊車(chē)輪盡可能以純滾動(dòng)的形式作不等距行駛,減少輪胎與地面的摩擦。普通差速器由行星齒輪、差速器殼(行星輪架)、半軸齒輪等零件組成。發(fā)動(dòng)機(jī)的動(dòng)力經(jīng)傳動(dòng)軸進(jìn)入差速器,直接驅(qū)動(dòng)差速器殼帶動(dòng)行星輪軸,再由行星輪帶動(dòng)左、右兩條半軸,分別驅(qū)動(dòng)左、右車(chē)輪。
本文主要是介紹了差速器外殼的加工工藝及加工中所需要的專(zhuān)用鏜床夾具的設(shè)計(jì)。首先對(duì)零件進(jìn)行了工藝性分析了解各加工面所需要打到的加工精度,確定各個(gè)加工面的加工余量。制定合理的能夠滿(mǎn)足加工需要的工藝方案。為了保證零件的加工精度需要進(jìn)行基準(zhǔn)面的選擇和對(duì)零件的定位,并遵循一定基本原則,并進(jìn)行定位誤差的分析。加工中還涉及到各種加床夾具的設(shè)計(jì)。本文主要介紹的是鏜床專(zhuān)用工藝方案的設(shè)計(jì),主要有夾具的定位,零件與零件的連接、夾具體與機(jī)床的連接和誤差分析。

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.
