Abstract
A belleville spring washer is in a ring dish shape, the thickness of the Belleville spring washer is larger than or equal to 10mm, the section of the belleville spring washer is in a rectangular shape, an A face is positioned above the belleville spring washer, wave-shaped protruded grains are arranged on the A face, the distance between the wave-shaped protruded grains is smaller than 3mm, a B face is positioned under the belleville spring washer, trapezoid protrusions are evenly distributed on the B face, the width of the bottom edges of the trapezoid protrusions is equal to the distance between the trapezoid protrusions, and the height of the trapezoid protrusions is 1/3 of the outer diameter of the belleville spring. The belleville spring washer is good in pre-tightening effect, convenient to use and install, good in sealing effect, low in service life and high in restoring force.
Description
Technical field
The utility model belongs to the spring material technical field, relates to a kind of disk spring washer.
Background technique
Spring is a kind of mechanical parts that utilize elastic working, generally makes with spring steel, impacts or shakes, stores up the size of energy, measuring force etc. in order to motion, the mitigation of controlling parts, is widely used in machine, the instrument.Divide by shape, mainly contain helical spring, belleville spring, spiral spring, leaf spring etc.Belleville spring is to produce a kind of elastic element that larger resiliently deformable is carried out work by himself, and the application in all kinds of machines is very extensive.
Saucer washer is to be designed for the lock washer that bolt is connected with screw, for the connection of medium or high-strength bolt, screw.Bolt tension force can bear owing to following reason produce lax: the wearing and tearing of easily damaged parts, creep, lax, thermal expansion, contraction, or the compression of Sealing.General processing method is that the choice for use packing ring carries out pretension, and a kind of elastic mechanical element can be installed in the flange bolt both sides, and enough pretightening force load is provided under very little distortion, thereby effectively reduces the risk of seal failure.But common saucer washer pretightening force is poor, when bolt is elongated or shorten, can not reach the comprehensively locking and tight effect of system, especially on more smooth and comparatively smooth surface, and locking and pretension weak effect.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of disk spring washer is provided.
Disk spring washer of the present utility model is to consist of like this, described disk spring washer is the annulus dish, thickness is more than or equal to 10mm, and the cross section is rectangle, is the A face above the disk spring washer, A has worn the waveform lug, waveform lug spacing is not less than 3mm, is the B face below the disk spring washer, and the B mask has equally distributed trapezoidal protrusion, trapezoidal protrusion base width equates with the trapezoidal protrusion spacing, and the trapezoidal protrusion height is 1/3 of disk spring washer external diameter.
B face with two disk spring washers during use overlaps, and trapezoidal protrusion staggers, and places between the connection part to get final product.After nut was fixing, two disk spring washer A faces were combined with surface of contact, and the ripple increase is frictional force therebetween, made it in conjunction with tight.
The utlity model has good beneficial effect, pretension is effective, and is easy to install and use, good sealing effect, and long service life, restoring force is high.
