Classification introduction of automobile reducer

There are two types of automobile reducer commonly used, single-stage and double-stage, which are arranged horizontally or vertically on the axle housing. The automobile reducer housing with two drive axles has two types: through and non-through. The through-type reducer shell is divided into two types: single through and double through. The reducer housing of some segmented axle housings is integrated with the middle section of the axle housing.

Heavy-duty trucks and mining dump trucks are required to have a larger reduction ratio and a larger ground clearance in order to adapt to multiple uses and complex road conditions. The heavy-duty vehicles produced by some foreign automobile manufacturers use planetary gear wheel reducers and bevel gear planetary wheel reducers. The advantage of this wheel-side reducer structure is that it has a smaller outline size to obtain a larger speed ratio, and it can be arranged inside the wheel. The materials of foreign reducer shells are gray cast iron, ductile iron, malleable cast iron and aluminum alloy.

A digital programmable controller is used on both automatic lines, and a rotary power head is used to adapt to the hole processing of various reducer shells and covers at different positions. An automatic inspection and compensation device is also set on the inner hole station of the fine wok.

In the multi-segment automatic line processing, the boss plane of the bearing cover is milled first, and then the second connecting surface of the reducer shell is processed. This plane is used as the positioning reference to process the flange end surface and outer circle, stir the bearing hole, and mill the inner end surface. , Drilling and tapping bearing cap bolt holes, drilling oblique oil holes, cutting internal threads, etc., clean and inspect after *. After installing the bearing cover, machine the earring hole and the oil injection hole from the rough, semi-finished, and refined shaft tube mounting holes at both ends. *After finishing the two pairs of bearing holes and the inner end faces of the driving bevel gear and differential assembly.

What are the characteristics of the CNC turning process?

What are the characteristics of the CNC turning process? Turning is a method of cutting the workpiece on the lathe by rotating the workpiece relative to the tool. Turning is the most basic and common cutting processing method. Most workpieces with revolving surfaces can be processed by turning methods, such as inner and outer cylindrical surfaces, inner and outer conical surfaces, end surfaces, grooves, threads, and rotary forming surfaces. Common lathes can be divided into horizontal lathes, floor lathes, vertical lathes, turret lathes and profiling lathes, and most of them are horizontal lathes.

The Influence of CNC Turning and Milling Machining on Turning Efficiency

The cutting efficiency of CNC lathes will be affected by human factors, environmental factors and the machine tool itself. Let's talk about the influence of cutting amount and cutting tools on CNC lathe processing among many factors.   Reasonable cutting amount can improve the efficiency of CNC lathe. When the   laser  cutting  speed is increased by 10 times and the feed rate is increased by 20 times, far beyond the traditional cutting forbidden zone, the cutting mechanism has undergone a fundamental change.   The result of CNC turning  and milling combined processing is: the metal removal rate per unit power is increased by 30% to 40%, the cutting force is reduced by 30%, the cutting life of the tool is increased by 70%, and the cutting left on the workpiece is greatly reduced. Heat, cutting vibration almost disappeared; cutting processing has taken an essential leap. According to the current situation of CNC lathes, increase the feed per tooth, improve pr...

Machining and welding process notes for TC4 titanium alloy parts

Common welding methods for titanium and titanium alloys are as follows: Argon arc welding, submerged arc welding, vacuum electron beam welding, etc. Tungsten argon arc welding is used for thicknesses of 3 mm or less, and argon arc welding is done for 3 mm or more. The purity of argon is over 99.99%, and the content of air and water vapor in argon is strictly controlled. Currently, for TC4 titanium alloys, argon arc welding, plasma arc welding are often used for welding, but both methods need to be filled with welding material. Limitations on shield gas, purity and effectiveness increase the oxygen content of the joint, reduce its strength and increase its post-weld deformation. Electron beam welding and laser beam welding are used. The following is a description of precision welding and precautions for TC4 titanium alloy. 1. Weld hole problem Table of Contents 1. Weld hole problem 2, internal quality of welded part 3. Weld depth and its variation 4, j...
