High-carbon steel and stainless steel standing size
Belleville spring washers are especially suitable for narrow space, load a lot of occasions. Through the combination of different sequences, each size can withstand a variety of load。

Material

	Spring steel Industrial -1074 - conforming to ASTM-A684
	Stainless steel Thickness less than or equal to 0.072 in. For industrial use - Type Model 302 The United States Government Administration Society 5 906 the Type Model 302 Chemistry only used only for the chemical industry Over 0.072 inches thick Type 17-7 PH certified to the AMS 5 528 in accordance with the United States Government Administration Society 5528
	If necessary, a certificate of competency can be provided free of charge. Can also provide a chemical analysis certificate, see price book。

Tolerance

Figure 2 shows the three parameters listed in the washer, the typical load - deflection curve, when the height of the middle value, the load can be estimated. "H" minus the "t, you can get the number of disk or conical。

For example

Use the number B1250-040 parts, and estimate the load deflection of 75%.

h = H - t = 0.082 - 0.040 = 0.042

h ÷ t = 0.042 ÷ 0.040 = 1 approx.

Can be drawn under the curve in Figure 2, h = t ", the deflection for 75% of the load pressure load of the usual 87%. Can be drawn from the table, the pressure calculation of the usual load of 330 lb.; .87 x 330 = 287 lb. The dotted line in Figure 2 shows the deflection of more than 75% load, the load characteristics of this region is not very reliable, because part of the washer is pushed to the lowest point。

Stack of Belleville spring washers
Single deflection of the Belleville spring washers are always relatively small, and therefore usually need many washers stacked up. Belleville spring washers are stacked, the deflection and gasket number is proportional to the load remains the same with the single washer load。

In order to increase the load, the washer will be shown in Figure 1 as parallel stacked. In theory, the load rate of increase is proportional to the number of washers. However, the gasket between the friction caused by the load-deflection curve is a significant "lag" (see Figure 3). This figure shows the system out of use of the B1000,-035 components in the case of laboratory equipment without vibration test curve. "Hysteresis loop width is required to be 6% of each parallel stacking washer, but it may be affected by the impact of lubricants and surface coatings to change, may also close to the surface of the friction changes in its mechanical lifetime. Five parallel experimental curves in Figure 3 also shows that the additional deflection due to the washer, and smaller. The graph in Figure 3 is to be marked to show the load and deflection of a single washer in the stack of washers.

Stacked washer can be installed in the spring pole or on the cylindrical sleeve. In dynamic applications, should guide the hardness increases to a minimum the Rockwell C48. Similarly, the hardness increases the flat end plate should also be added to prevent the recessed adjacent parts。

Belleville spring washers for flange mounting

Stainless steel standing size
Flange Belleville washers designed to offset the thermal expansion and bolt connections related to mechanical vibration. Typical uses include: valves, pipe connections, connect pump, pressure bonding. Package on these washers have been in the production process to be removed.

Belleville spring washers for flange mounting

Standing high-carbon material just the size
HENRY high load Belleville washer has a much larger load than a similar diameter standard washers. Package on these washers have been removed in the production process, because the vast majority of applications belong to the static。

Material

	When used in the production of processed carbon steel C1070-C1075 or chrome vanadium steel。
	Certificate of chemical analysis require additional charges。
	Parts made from Stainless steel17-7PH special orders
