Description
Technical field
The utility model belongs to Sealing technical field, relates in particular to one and exempts to tear open the exoskeletal dual-oil seal lip of machine shafting oil envelope.
Background technique
By a circular metal skeleton for shaft sealing oil sealing at present, on metal frame, establish the oil seal lip that rubber is made, in oil seal lip, coated spring is tried to stop people from fighting each other, rubber oil sea lip plays oil sealing object, short by dry rubber substance wear-out life, and therefore the working surface between oil sealing and axle is very easy to leakage of oil, cause pumping unit for oil field, speed reducer often to change oil sealing, must often employ crane and pull down heavy crank and change slight deceleration feather cockscomb shafting oil envelope, not only waste time and energy, return maintenance man and caused numerous inconvenience.The application's designer once disclosed the patent No.: ZL201220093414X, name is called: the patent application of exempting from the exoskeletal shafting oil envelope of the machine of tearing open.Although effect is remarkable, there are some drawbacks, because the oil seal lip of oil sealing is single, and be arranged on a side of seal ring, some deficiency of wear resistance and intensity.
Summary of the invention
The purpose of this utility model be to provide a kind of just can maintain and replace without detaching equipment exempt from the exoskeletal dual-oil seal lip of the machine of tearing open shafting oil envelope.The utility model solves the scheme that its technical problem adopts: one exempts to tear open the exoskeletal dual-oil seal lip of machine shafting oil envelope, comprise oil seal washer, oil seal lip, spring ring, potted line and auxiliary oil seal lip, it is characterized in that: in oil seal washer, with oil seal lip and auxiliary oil seal lip, the second oil seal lip and the second auxiliary oil seal lip are oppositely set, the second spring is set on the second oil seal lip, the utility model has adopted dual-oil seal lip has been set in oil seal washer, increase the area of contact with axle, improve sealability, and increased wear resistance.
The utility model long service life, the fresh oil that more changes the outfit when envelope, can complete without detaching equipment, save time, laborsaving, province's fund.
