The flat gasket is a gasket whose upper and lower end faces are flat. The flat gasket used in the automobile differential is installed between the casing and the gear of the differential like the spherical gasket to reduce friction and reduce friction. Improve lubrication. The differential should accommodate severe bumps and be able to operate at high speeds for long periods of time in high and low temperature environments. Since both ends of the flat gasket currently used in the differential are smooth, or only one side end face of the flat gasket is provided with small concave points, during the high-speed operation of the differential, the flat gasket The lubrication of the contact surfaces is not ideal, and the friction between the contact surfaces is large, which is prone to failure.

Existing bolt and nut connections usually use threads for connection, and this connection method has two main drawbacks. First, tools are required to be used to lock it during installation, and it takes a long time to complete, which is time-consuming and labor-intensive; Second, the installed bolts and nuts are prone to loosening after a period of time, resulting in loosening and shaking between the connecting parts.

The height of the existing assembly devices is fixed, and the height of the workers is different, so it is very inconvenient to use, resulting in a decrease in efficiency. With the progress of science and technology and the development of society, people have proposed higher assembly devices. Therefore, we propose a shaft card assembly device to solve the above problems.

The produced screws, due to unreasonable production aspects, are likely to cause quality problems in the screws. During production, many screw quality problems may be found upon delivery. Let's talk about the quality problems often encountered by screws and the reasons for the quality problems, and finally put forward some solutions. 1. The head of the screw is deformed and the head is crooked. The possible reasons are the poor installation of the first punch of the screw die and the improper adjustment of the machine. 2. The head of the screw is not round. The reason is that the selection of the first punch of the screw mold is improper or the first punch is not full enough. 3. The screw has burrs or burrs. The reason is the poor forming of one punch, mainly caused by too large gap between punch and die hole or too short punch. 4. The screw head is cracked and the screw head is cracked. The reason may be that there is a problem with the quality of the screw wire itself, so before the screw wire is headed, the quality department must check it and use the potion. Especially the stainless steel screw wire, it is necessary to check that it is stainless steel 201 and that is stainless steel 304. It is also possible that a die is used incorrectly (such as a die with a hexagonal washer head for a pan head), and the viscosity of the lubricating oil fails. For the problem of the screw head, you can read the article written by Manager Zhu above - high-strength screw fracture or head crack detection. In this article, some problems encountered by the screw head and how to detect the screw head problem are clearly introduced [4]. The common quality reasons for screws are of course more than the above, this is only part of it. There are other quality issues, then Manager Zhu will talk about it. The above screw quality reasons are for reference. If you encounter these problems, you can try the solutions proposed.

With the development of the economy, automobiles have become an indispensable means of transportation in people's lives, and the production, sales and after-sales services of automobiles have also developed rapidly. Automobile wheels and steel rings are an important part of auto parts and are also related to The use of the car is safe. The connection between the car wheel and the steel ring is realized by bolts, so the bolts and nuts need to have good fixation.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: DIN316 butterfly screws and bolts, fine and coarse hexagonal screw caps, color zinc enlarged and widened flat washers, thumb screws and other products, we can provide products such as You have the right fastener solution for you.
