Abstract
The utility model discloses a weldless screw multi-amplitude spring, consisting of a screw spring body, wherein the screw spring body is provided with a plurality of screw multi-amplitude layer, and the screw multi-amplitude layer is provided with a wave crest and a wave trough. The utility model is adapted to storing compensatory power in the sealing element.
Description
The utility model relates to a kind of nothing welding spiral multilayer wave amplitude spring.
In order to store the spring of compensation power, be in the existing seal with individual layer corrugated sheet spring or the two-layer corrugated sheet spring that welds together.This corrugated sheet spring has that volume is little, and rigidity is big, and in light weight the grade used advantage.But the shortcoming of this wave plate spring is: two stacks of (1) as many as, its working stroke is very short, makes it still can not replace Round Steel Wire type spiral seals spring in many occasions.(2) in installation and working procedure, unsurmountable radial deformation takes place and can not get compensation in spring.If be not spring radial deformation leaving space, then can cause the reduction of seal life-span, if stay deformation space, influence the rigorous of seal configuration again.(3) chance high temperature in solder joint place easily becomes fragile, fracture easily in the use.
The purpose of this utility model is at above-mentioned shortcoming, and a kind of nothing welding spiral multilayer wave amplitude spring is provided.
The utility model is made up of the coil type spring body for there not being welding spiral multilayer wave amplitude spring, and the spring body is provided with some spiral wave mode laminations, the trough that each spiral wave mode lamination is provided with crest and is adjacent.
The utility model compared with prior art has following obvious advantage:
1, the utility model has not only guaranteed the advantage of original wave amplitude spring, and owing to be that spiral is formed, has overcome the deficiency of original wave amplitude spring again, has prolonged working life, has reduced the cost of investment of seal.
2, since the present technique product form by a plurality of spiral wave mode laminations unrestricted, so its working stroke is unrestricted.
3, install and during work, the radial-deformation of each spiral wave mode lamination can be delivered to (or down) spiral wave mode lamination along spiral wave mode lamination tangent direction, the spiral wave mode lamination at two ends guarantees that it is of a tightly knit structure by moving ending point position with the compensation amount of deformation again thereby guaranteed not influence seal in the time of the life-span.
The utility model is applicable to store in the seal to mend tastes power.
The utility model will be further described below in conjunction with drawings and Examples.
Fig. 1 is the utility model overall structure figure.
Fig. 2 is the utility model extended state figure.
Fig. 3 overlooks phase diagram for the utility model.
As shown in Figure 1, the utility model is made up of coil type spring body 1, is provided with some spiral wave mode laminations 2 on coil type spring body 1, the trough 4 that spiral wave mode lamination 2 is provided with crest 3 and is adjacent.
As shown in Figure 2, the spiral wave mode lamination 2 on the coil type spring body 1 is provided with crest 3 and trough 4.
As shown in Figure 3, spiral wave mode lamination 2 is provided with crest 3 and trough 4.
The utility model is applicable to the compensation combination of various mechanical seals.
