	Basics of Design Engineering - Fastening and Joining - Nonthreaded Fasteners - Washers
		Washers are primarily used as a seat to distribute load, but they may also provide spring tension, span oversize holes, insulate, seal, or provide electrical connection.
		Type B washers are of higher quality and are specified in narrow, regular, and wide diameters for each screw size from No. 0 to 3 in.
		A flat washer used in conjunction with a spring washer may often be replaced with this type of conical washer.

	Clutch cover assembly and clutch incorporating same - Patent 4696384
		Clutch cover assembly according to claim 1, wherein said Belleville washers are adapted to exert a resultant force on said pressure plate on a circumference the diameter of which is intermediate those of circumferences delimiting an active part of said pressure plate through which it is adapted to bear axially on a friction disk.
		To alleviate this disadvantage it has been proposed to arrange for the Belleville washer to exert its force on the pressure plate on a circumference the diameter of which is substantially intermediate the diameters of the circumferences delimiting the active area of the pressure plate.
		As two Belleville washers 50A, 50B are associated wtih the annular flange 68 forming a piston and thus constitute the corresponding engagement means 14, both the Belleville washers 50A, 50B bear on the pressure plate 13 through the intermediary of the annular flange 68 forming the piston.

	How To Use Belleville Washers Correctly
		The Belleville is a disk spring that applies pressure to the connection once you clamp down on it with the proper amount of force.
		The advantage of this washer is that it applies clamping pressure along a continuous arc pattern, instead of concentrating it at one point the way a split-ring lockwasher does.
		The flat washer deflects (bends) away from the Belleville washer, instead of transmitting clamping force to the connection.

	Belleville Washers — Spring Steel Washers - Assoc Spring UK
		Belleville spring washers are especially suited for high loads in small spaces.
		Since the deflection in a single belleville spring washer is relatively small, it is often necessary to combine a number of washers.
		The width of the "hysteresis" loop is in the order of 6% for each washer added in parallel, but it may vary with lubrication and surface finish and may change during the life of the mechanism due to burnishing of adjacent surfaces.

	The Trouble with Torque in Electrical Connections
		The washer must flatten at the proper force and many applications do not use a high enough force.
		In addition, since the bow in the washer is difficult to see, Bellevilles are sometimes installed upside down.
		If you choose a Belleville that flattens at the desired force, you then can proceed with implementing the connections and not worry about a torque value.

	Cloverspring: CloverDome Technical Data
		The height of a Belleville washer is only 3% of its diameter.
		The result is a spring rate lower than that of stiff Belleville washer, but significantly higher than the spring rate of a coil spring, for an equal amount of deflection.
		To demonstrate the different spring rates between CloverDome™, Belleville, Curved, Wave and Finger springs, a simple equation referred to as “Coefficient of Compliance” (CC) is shown in Table 1.
