Abstract
The utility model provides a bearing used for waste gas recycling valve which is characterized by including a graphite bearing core; and the outer surface of the graphite bearing core is provided with a steel sheath. The bearing used for waste gas recycling valve provided by the utility model has the advantages of leading products to have effects same to that under a cold state under the high temperature situation of products as graphite is provided with the properties of lubricating and high temperature resistance, reduces the product cost and can not generate negative influences to product appearance.
Description
Technical field
The utility model relates to the exhaust gas recirculation valve bearing.
Background technique
Existing exhaust gas recirculation valve bearing is a copper-base powder metallurgy, and there is following problem in this kind form: make easily behind the high temperature and valve shaft generation clamping stagnation, cause gas leakage, reduce engine performance; Owing to continuous rising of the price of copper increases product cost; Powder metallurgy contains oil, and greasy dirt oozes out behind the high temperature, causes the product surface degraded appearance.
Summary of the invention
The purpose of this utility model is to provide a kind of clamping stagnation, exhaust gas recirculation valve bearing with low cost of not taking place.
The utility model provides a kind of exhaust gas recirculation valve bearing, it is characterized in that: mainly comprise the graphite bearing core, the outer surface of graphite bearing core is surrounded by sheetmetal.
The exhaust gas recirculation valve bearing that the utility model provides, the endoporus inoperative of its graphite bearing core part can also be surrounded by sheetmetal, to strengthen combining of graphite bearing core and sheetmetal.
The exhaust gas recirculation valve bearing that the utility model provides, its advantage is: because graphite has lubricated and resistance and high temperature resistance property, so, under the product high-temperature condition, make product have the effect same with cold conditions; Reduce product cost; Can not have a negative impact to product appearance.
Description of drawings
Fig. 1 is the structural representation of exhaust gas recirculation valve with bearing.
Embodiment
Exhaust gas recirculation valve bearing, its structure comprise graphite bearing core 1 as shown in Figure 1, and the outer surface of graphite bearing core 1 and endoporus one end inoperative partly are surrounded by sheetmetal 2.
Claims (2)
1. exhaust gas recirculation valve bearing, it is characterized in that: mainly comprise the graphite bearing core, the outer surface of graphite bearing core is surrounded by sheetmetal.
2. according to the described exhaust gas recirculation valve bearing of claim 1, it is characterized in that: the endoporus inoperative part of described graphite bearing core also is surrounded by sheetmetal.
