Abstract

The utility model discloses a spring assembly of a vibration damper, consisting of two main springs, two bronze spacers and a middle spacer; wherein, two surfaces of the middle spacer are respectively fitted with the inner surfaces of the two bronze spacers; and the outer surfaces of the two bronze spacers are respectively laminated with the two main springs. The spring assembly of the vibration damper is characterized in that oil grooves are opened on the inner surface and the outer surface of the bronze spacers. With simple processing technique, the spring assembly of the vibration damper can improve the lubricating effects of the bronze spacers and springs and reduce damages to the springs.

Description

The vibration damper spring assembly

Technical field

The utility model relates to a kind of vibration damper spring assembly, specifically, relates to a kind of spring assembly that is used for large-scale vibration damper.

Background technique

At present, large-scale vibration damper gasket assembly is made up of two main reeds, two bronze pads and a slice intermediate washer, fit with the internal surface of two bronze pads respectively in two surfaces of intermediate washer, the outer surface of the two bronze pads two main reeds of fitting respectively, they are assembled together under the effect of fastening ring, when main reed is moved by external force, rub with bronze pad, because unlubricated dose of existence between bronze pad and main reed, main reed causes breakage easily in friction.

The model utility content

The purpose of this utility model is to provide a kind of vibration damper spring assembly, can improve the lubrication between bronze pad and main reed, reduces the breakage of reed.

To achieve these goals, the technical solution of the utility model is as follows: a kind of vibration damper spring assembly, form by two main reeds, two bronze pads and a slice intermediate washer, fit with the internal surface of two bronze pads respectively in two surfaces of described intermediate washer, the outer surface of the two bronze pads two main reeds of fitting respectively, it is characterized in that: the inner and outer surface at described bronze pad all has oil groove.Outside lubricant oil enters between main reed and the bronze pad and the space between bronze pad and the intermediate washer by oil groove, plays lubrication.

Described oil groove is " ten " font or " well " font." ten " font and " well " font oil groove can strengthen lubricated area, and processing is simple." ten " font oil groove conveniently is used for the less vibration damper spring assembly of area, and " well " font oil groove conveniently is used for the bigger vibration damper spring assembly of area.

Described oil groove is a groove.Like this, outside lubricant oil just can enter oil groove, plays lubricated effect.

Beneficial effect: compared with prior art, the utility model improves the lubrication of bronze pad and reed by offering oil groove on bronze pad two sides, reduce the breakage of reed, adopt the oil groove of " ten " font or " well " font simultaneously, strengthened lubricated area, and processing technology is simple.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A portion enlarged view of Fig. 1;

Fig. 3 is bronze pad plan view of the embodiment 1;

Fig. 4 is bronze pad plan view of the embodiment 2.

Embodiment

Further the utility model is illustrated below in conjunction with drawings and Examples.

Embodiment 1:

As shown in Figure 1, 2, 3: a kind of vibration damper spring assembly, form by two main reeds 1, two bronze pads 2 and a slice intermediate washer 3, fit with the internal surface of two bronze pads 2 respectively in two surfaces of described intermediate washer 3, the outer surface of the two bronze pads 2 two main reeds 1 of fitting respectively all have oil groove 4 at the inner and outer surface of described bronze pad 2.Described oil groove 4 is " ten " font, and this oil groove 4 is a groove.

Its working principle is as follows:

Lubricant oil enters between bronze pad 2 and the main reed 1 by oil groove 4 and between bronze pad 2 and the intermediate washer 3, when being subjected to external force, main reed 1 is moved as the time spent, main reed 1 rubs with bronze pad 2, lubricant oil between them can reduce friction factor, thereby reduces the breakage of main reed 1.

Embodiment 2:

As shown in Figure 4: present embodiment and embodiment's 1 structure are roughly the same, and its difference is: described oil groove 4 is " well " font.

The present embodiment working principle is identical with embodiment 1.
