Arrangement type and structure of the drive shaft

Since the drive axle and the frame are flexibly connected, the universal transmission consisting of cross shaft universal joints cannot guarantee equal speed transmission in any case, so the drive shaft is used.

Symptoms, causes and elimination of automobile timing gear rattling

Gear timing noise is a kind of "cough, cough" rolling noise caused by poor gear fit or flaking, rough tooth surface. The timing gear meshing gap is too large, and the engine makes a slight "click, click" sound at idle speed.

Gear steering principle

Gear steering is equipped with gears that transmit steering input to the linkage and other components that allow the wheels to turn and run properly. It essentially adds steering variation, allowing the front wheels to move faster than the steering wheel. Depending on the type of steering gearbox, this is accomplished by increasing the steering force and transmitting that force to the steering linkage.

Use of gear steering

Gear steering is typically used in the steering system of a car to convert the rotational motion of the steering wheel into left and right motion of the wheels. The steering wheel rotates the gears that engage the rack and pinion. The main components of the gear steering include the tie rod, shaft and rack and pinion. The gear steering in an automobile steering system can be considered a very important part of the steering control of an automobile vehicle, responding well to the driver while driving. The gear steering control makes the car feel safe while driving.

How can foundry manufacturers improve the quality of cast iron parts?

Strive to improve the casting process. Before production, casting manufacturers should figure out the size, weight and structure of cast iron parts and other parameters, choose the appropriate alloy processing, and with a reasonable riser and pouring system, so as to minimize the processing defects of cast iron parts and obtain high-quality cast iron products.

How to effectively avoid the fracture of gray cast iron parts?

the modeling design of gray cast iron parts. Irregular cross-section of casting parts (sudden thick and thin or sudden convexity of casting), too small inner rounded corners, and failure to set reinforcement bars will cause poor local design of gray cast iron parts, so that a little carelessness in handling will cause fracture of casting parts.

Stainless steel precision casting problems and solutions

Hammer head jamming. In casting, if the phenomenon of hammer head jamming occurs, it will directly lead to the suspension of the casting process. Therefore, in the casting process, the casting workers should often measure the temperature of the hammer head and cylinder, to avoid the high temperature caused by the hammer head jammed. Not only that, the choice of alloy materials without impurities, to prevent impurities stuck in the hammer head, but also can effectively avoid the hammer head stuck.

How can foundry manufacturers solve the problem of sand trapping in castings?

How does sand trapping occur? During the pouring process, the scouring and baking effect of high temperature metal liquid makes the water in the sand evaporate and the volume expand at the same time, which causes the surface layer of the sand to buckle or crack, thus the phenomenon of sand trapping occurs. There are three main forms of sand trapping, namely, "sand trapping scar", "rat tail" and "groove". On the surface of the casting part, it is mainly manifested as scar-like projections, fine lines with sand and striped grooves.

How to avoid gas cutting defects in large cast steel parts?

Cast steel parts of the gas cutting process is mainly the use of oxygen and acetylene gas mixture burning flame, heating the cutting place, as the temperature rises to a certain range, and then use the cutting gun cutting nozzle pure oxygen hole in the spray of oxygen to make the cutting place violent combustion, combustion of the resulting oxidized steel blown off by the oxygen flow, and constantly form the cut, so as to complete the entire gas cutting cutting cutting process.

What are the principles of casting parts processing?

The choice of raw materials should be strict. Metal raw materials, the quality of the finished casting has a direct impact. Less inclusions in the metal material, the quality of the metal liquid during melting is high, and the quality of the castings produced is good.
