Abstract
The invention discloses a frameless contact-type oil seal. The frameless contact-type oil seal comprises a fluoro-rubber seal body and a compression spring, wherein the oil seal is elastically connected with the bearing base side cover; the fluoro-rubber seal body is in interference fit with a shaft; a lip groove and an oil guiding hole are formed in the part one third of the fluoro-rubber seal body. The frameless contact-type oil seal guarantees that the lubricant cannot flow out to pollute the environment, the oil can bear a certain pressure to ensure uniform lubrication of the whole body by the oil, and the temperature rise of the oil, caused by friction between the oil seal body and the shaft, is avoided.
Description
Technical field
The present invention relates to a kind of oil sealing, be specifically related to a kind of contact oil seal of centrifugal blower.
Background technique
Under the overall background that requires to tend towards superiority at environment protection emission, recirculating fluidized bed power station unit is because burning low grade coal, gangue, slime etc., and can realize the relative low temperature burning, meet national industry development guiding, the supercritical circulating fluidized bed National Development and Reform Committee's electric power development directory items that belongs to of 600MW, non-contact oil seal and the oil sealing great majority of centrifugal blower are in the past taked, such as labyrinth oil sealing etc., the characteristics of labyrinth oil sealing are simple in structure, easy for installation, but higher to requirement on machining accuracy, also occurred in the past not causing oil leakage phenomenon because machining accuracy reaches, the fan bearing of the supercritical circulating fluidized bed overfire air fan of 600MW is taked pressure lubrication, the Xi petrol station can apply very large oil pressure to bearing housing, and traditional labyrinth oil seal such as machining accuracy do not reach, and gently then lubricant oil spills the pollution site environment, situation seriously may burn out a bearing, and brings loss.
Summary of the invention
Goal of the invention: the objective of the invention is in order to remedy the deficiencies in the prior art, a kind of exoskeletal contact oil seal that prevents outflow of lubrication oil and can bear certain oil pressure is provided.
Technological scheme: a kind of exoskeletal contact oil seal, comprise fluorine rubber seal element body and Compress Spring, described this body elasticity of fluorine rubber seal element is connected in the bearing support side cover, described fluorine rubber seal element body and main shaft adopt interference fit, and 1/3rd places of fluorine rubber seal element body are provided with lip groove and oil diverting port according to this.
Seal body has adopted fluorine rubber (FKM), and fluorine rubber still has good physical property under high temperature (the highest 250 degrees centigrade) condition.Also have extraordinary oil resistant, fuel oil, solvent and chemical product performance.
Described elasticity is connected to the spring that is provided with by fluorine rubber seal element body outer ring and is connected with the bearing support side cover.Make like this oil sealing and bearing support side cover that certain expansionary force is arranged, simultaneously also convenient mounting or dismounting.
Beneficial effect: after the present invention has adopted such structure, can prevent outflow of lubrication oil and can bear certain oil pressure, so that lubricant oil can evenly lubricate to whole.Avoid generating heat because of oil seal body and main shaft friction, cause oil temperature to raise.
Description of drawings
Accompanying drawing 1 is structural representation of the present invention.
Accompanying drawing 2 is assembled state schematic diagram of the present invention.
Embodiment
The invention will be further described below in conjunction with specific embodiment.
