Lock Stainless Steel Washers Manufacturers Spring Washer Flat Spring Washer

Spring washers are widely used in the load-bearing and non-load-bearing structures of general mechanical products. They are characterized by low cost and easy installation, and are suitable for parts with frequent assembly and disassembly.

Spring washers are used to prevent loosening. Flat washers do not have a loosening prevention function. Flat washers only increase the contact area. Spring pads are used to prevent vibration from loosening.

The main function of the flat washer is to protect the surface of the connector from scratching the surface of the workpiece when the bolt and nut are tightened; the spring pad is anti-loosening. However, some important connections, such as places that rely mainly on compression to generate friction to transmit power, cannot use spring pads. They reduce the rigidity of the connection and are prone to problems. It is not necessary to use a spring washer. When the strength of the connected parts is low, flat pads or flange bolts are used to increase the contact area. Flat pads mainly increase the contact area. Spring washers are anti-loosening, and are relatively large when there is vibration, pulse, and medium temperature When fluctuating, be sure to use a spring washer. The spring pad can increase the pre-tightening force and has a loosening prevention effect, while the flat washer does not.

What is a retaining ring for shaft?
Spiral circlips are different from traditional stamped circlips. Spiral circlips adopt a winding manufacturing process for precise diameter and size requirements. They have a uniform cross section (anti-interference earless assembly) and no burrs. Spiral retaining rings meet the specifications of the military and aerospace industries and are used in thousands of mechanical products worldwide. Ordinary cassette retaining rings have ears in their structure, which cause interference with internal parts. The elastic retaining rings made of stainless steel have the same cross-section and no ears, so they will not be between the matching parts after installation. Interference occurs, and the cost of the elastic retaining ring is lower than that of the cassette retaining ring. The use of the elastic retaining ring can eliminate the pillow block design, reduce the size of the shaft, and save material and processing time. The wave shaped retaining ring is a wave-shaped Remove the retaining ring. A wave retaining ring can replace a retaining ring and a wave spring. It can apply pressure to the ball bearing in advance, and it is also assembled in the groove like a normal retaining ring. The double-ring offset outer retaining ring is used as a substitute Pillow block. It is used to fix the nozzle parts and make it easy to assemble. The width of the retaining ring is designed to be zero interference, and its outer diameter is smaller than the diameter of the thread root. In the pressure gauge, the wave retaining ring is installed in a shallow groove. The surface glass only generates a very small pressure. In this way, the retaining ring can fix the surface glass without crushing the glass. The retaining ring forms side walls on both sides of the timing pulley. This method eliminates the press-in side walls. It is convenient to replace the belt, and the retaining ring on one side is easy to disassemble. The wave retaining ring is easy to meet the requirements of on-site maintenance. If the hydraulic cylinder sealing ring needs to be repaired, the retaining ring can be quickly removed with a screwdriver and easily reinstalled. The purpose of the elastic retaining ring There are many more, if you want to know, please contact our company. In addition, the wave spring has a wide range of uses, such as adjustable pulleys, bearing preload, electrical connections, hydraulic seals, clutches, ball valves, fluid valve couplings, etc.

Elastic retaining ring characteristics: 1. The earless design of the retaining ring makes the retaining ring and accessories not interfere with each other;

2. Circlip ring crystal winding forming, compared with the traditional stamping process, the mechanical performance is more stable; 3.360° plane, stable size; 4. More than 5000 kinds of standard retaining rings (diameter 6.5 ~ 406mm); 5. Special customized non The standard retaining ring does not require mold opening costs (diameter 5~2300mm); 6. Easy to install and disassemble.

Expansion ring of spring washer and cause of hydrogen embrittlement fracture

1. Spring washer ring expansion phenomenon is generally not a problem of the spring washer itself
2. The spring washer that has undergone the expansion ring must be subject to a radial external tension. The external tension results from the tightening axial force generated by the tightening torque.
3. The external chamfer of the bearing surface of the nut produces a radial component of the axial clamping force, thereby expanding the opening of the spring washer. The smaller the chamfer diameter, the greater the possibility of swelling
4. Adding a flat washer between the nut and the spring washer can help slow down or prevent the occurrence of the expansion ring, but the flat washer is too thin or too soft to prevent the expansion ring from occurring
5. The reason for hydrogen embrittlement fracture of spring washers is generally that the heat treatment process is unreasonable and the fracture is caused by the galvanization without dehydrogenation treatment in time.
Extensive experiments and long-term practical experience confirm the above analysis.

How to choose a spring manufacturer? We can judge by inspecting the following 10 points of spring manufacturers:
1. Types of springs that can be produced.
Different types of springs require different production equipment. The more types that can be produced, the more complete the production equipment of the company.
2. Ask about the production accuracy of the spring.
The precision of producing springs represents the production technology capability of the spring factory. The higher the production precision, the more attention the spring factory pays to the quality of the products.
3. Whether there is a research and development team.
The R&D team is indispensable for an enterprise. The R&D team of the spring factory can make this enterprise develop in the direction of new processes and new technologies. ~Innovative ability
4. Whether the production equipment is imported.
Most of the domestic spring equipment is used to produce some non-important parts of the spring, the overall production accuracy is low, and there is a certain gap in product consistency. The higher the precision of the spring equipment, the higher the precision of the spring can be made.
5. Output of spring production.
The production output of springs represents the production capacity of this enterprise. The greater the production capacity, the stronger the supply capacity and the stronger the relative delivery guarantee.
6. Which manufacturers are the suppliers for?
As the saying goes, to marry a wife, you must choose the right person, and you also need to find a partner. For example, you are in the automotive industry, and Xinxiang Huispring Spring Co., Ltd. is a spring for the automotive industry. They directly supply the German Bosch company, so the product quality must be very guaranteed. This is very suitable for you. If you are making a ballpoint pen and you want an ordinary ballpoint pen spring, then this bright spring spring may not be suitable for you. You should choose an ordinary spring factory.
7. Whether there is a special testing department and whether the testing equipment is complete.
The inspection department is a necessary department of the spring enterprise. If no one supervises quality control, or quality control cannot use effective equipment for inspection, then no one would dare to use such products.
8. What is the defective rate of the spring produced? ,
The defective rate of springs of qualified spring manufacturers is generally between 5 and 12 parts per million. This data contains the data of nonconforming products detected by the manufacturer. The smaller the data, the stronger the accuracy and consistency of spring production.
9. Where are the raw materials of the springs purchased and whether they are inspected plate by plate.
The production process of the spring is very important, and the raw material of the spring is more important. For the same material, some material dealers sell it for 5 yuan, and some material dealers sell it for 10 yuan. Why is this? On the one hand, it is the consistency of the steel wire, such as some places where it is thick and some places, on the other hand, whether the composition of the spring material is evenly distributed and whether the content is qualified. The spring produced by unqualified spring raw materials is also unqualified, such as frequent breakage or deformation, and the spring load cannot be reached.
10. Whether it has the qualification certificate of the relevant industry.
For the spring industry, are some certificates very difficult to obtain, such as IATF16949 and GJB 9001C. These are very rare certificates. If this spring company has these qualifications, at least it proves to be very formal.
Finally, we still have to conduct on-site inspections and see how much the registered capital of this spring factory is, so as to avoid subsequent supply problems.
