Abstract

The utility model discloses a shock ring, consisting of a rigid part and an elastic part, wherein the rigid part and the elastic part are embedded with each other and are made of metal materials and rubber materials respectively. The flexibility of the shock ring is improved because the shock ring consists of the rigid part and the elastic part, and the shock ring is firmer by embedding the rigid part with the elastic part, so the vibration and noise generated by a machine during the running of a system are effectively reduced, the safe running of the system is ensured and the overall service lives of machines in the system are also prolonged; and in addition, as elastic materials have low cost, the cost of the shock ring is also reduced.

Description

A kind of shock ring

Technical field

The utility model relates to hydraulic machinery, is specifically related to a kind of shock ring.

Background technique

At present, on the domestic hydraulic system, be to be rigidly connected all over what adopt, damping effect is relatively poor, system in operation, vibrate and noise bigger, can produce very big influence to the running and the surrounding enviroment of machine, also can reduce the working life of machine simultaneously.

The model utility content

Goal of the invention: the purpose of this utility model is in order to solve the deficiencies in the prior art, a kind of shock ring that reduces vibration and reduce noise to be provided.

Technological scheme: in order to realize above purpose, a kind of shock ring described in the utility model, it is made up of hard part and elastic part.

Wherein, preferably, described hard part and elastic part are entrenched togather mutually.

Wherein, preferably, described hard is partly made for metallic material, and described elastic part is made by rubber material.

Wherein, preferably, described metallic material is steel material or aluminum material.

Wherein, preferably, described rubber material is a vulcanized rubber.

Wherein, preferably, the elastic part of described shock ring bottom is provided with sealing lip.

Wherein, preferably, described sealing lip is a circle.

Beneficial effect: a kind of shock ring that the utility model provides, because adopting hard part and elastic part forms, thereby improved the suppleness of shock ring, and hard part and elastic part are entrenched togather mutually, make shock ring more firm, can reduce effectively and machine produces when reducing System Operation vibration and noise, not only guaranteed the safe operation of system, also improved the working life of total system machine, and, also reduced the cost of shock ring simultaneously because the elastic material cost is lower.

Description of drawings

Fig. 1 is a plan view of the present utility model;

Fig. 2 is the sectional view of the utility model plan view A-A.

Embodiment

Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.

A kind of shock ring as shown in Figure 1 and Figure 2, it is by hard part 1 and elastic part 2 mutual chimeric being integral.Wherein, hard part 1 is made (metallic material all can, as aluminum alloy material) for steel material, and elastic part 2 is made (rubber material all can) by vulcanized rubber.Elastic part 2 in described shock ring bottom is provided with a circle sealing lip 3.

The utility model is used for the connection of hydraulic system machinery compartment; connect as many pumps, being rigidly connected in the hydraulic system become flexibly connect, can reduce the vibration of machinery compartment; also can reduce noise 4-8dBA effectively; have fail safe, can bear heavy load, oil resistant; has very good damping performance; the utility model is cast with sealing lip 3 simultaneously, need not to install additional in addition seal ring, just can obtain good sealing effect.

The foregoing description only is explanation technical conceive of the present utility model and characteristics, its objective is to allow to be familiar with these those skilled in the art and can to understand content of the present utility model and enforcement according to this, can not limit protection domain of the present utility model with this.All equivalents or modifications of having done according to the utility model spirit all should be encompassed within the protection domain of the present utility model.
