Abstract
The utility model discloses an oil blanket for rotary shaft seal, including outer skeleton, the inside of skeleton is equipped with endocyst gel oil and seals outside, and the inner wall that seals at endocyst gel oil is equipped with the dust ring lip, and the lower extreme inner wall that seals at endocyst gel oil is equipped with the oil blanket lip, is equipped with the annular groove respectively in the both sides of dust ring lip, and it has two O type circles to overlap on outer skeleton, two O types circle corresponding with the position of two rings connected in star respectively, be equipped with spring mounting groove in the position of the lower extreme correspondence oil blanket lip of outer skeleton, be equipped with the spring in spring mounting groove. The utility model discloses the extension of outer skeleton and adopted the twice external seal to has improved the assembly precision, has reduced the installation requirement, the outer skeleton of this oil blanket the taking out the oil blanket in the mounting hole that an external screw thread can be very convenient of having integrateed in addition, tobacco processing and cigarette manufacturing machinery equipment can relax when the maintenance dismantle and the installation also can improve the oil blanket installation accuracy with the oil blanket.
Description
Technical field
This utility model relates to fluid technical field of sealing technology, particularly relates to a kind of oil sealing for rotation axis seal.
Background technology
A lot of cigarette machinery equipment have transmission case, the input and output shaft of transmission case are equipped with oil sealing and do not cause leakage to be sealed by the fluid in transmission case, cigarette machinery equipment poor working environment in real work, long running is in high temperature, dust, the environment of pressure alternation, easily cause the aging of oil sealing and outside dust ring, abrasion causes leakage, transmission case or the volume of a lot of cigarette machines are big, or the compact dismounting in installation position is difficult thus causes oil sealing dismounting difficulty on power transmission shaft, take time and effort when maintenance, another tradition its narrower width of oil sealing, coordinate tighter, during installation easily in hole tilted cause axiality between oil sealing and power transmission shaft bad or install time tap oil sealing oil sealing is struck bad, thus reduce the service life of oil sealing.
Utility model content
This utility model purpose is contemplated to make up the defect of prior art, it is provided that a kind of oil sealing for rotation axis seal.
This utility model is achieved through the following technical solutions:
A kind of oil sealing for rotation axis seal, include purchasing ore, interior encapsulated oil sealing it is provided with in the inside of purchasing ore, inwall at interior encapsulated oil sealing is provided with dust ring lip, lower end inner wall at interior encapsulated oil sealing is provided with oil seal lip, it is respectively provided on two sides with annular groove at dust ring lip, purchasing ore is cased with two O, two described O are corresponding with the position of two annular grooves respectively, it is provided with spring mounting groove in the position of the lower end correspondence oil seal lip of purchasing ore, in spring mounting groove, is provided with spring.
It is provided with step extension in the upper end of purchasing ore, is provided with complementary screw-threads in the outside of extension.
The utility model has the advantages that: the prolongation of this utility model purchasing ore and have employed twice external seal, thus improve assembly precision, reduce installation requirement, this oil sealing purchasing ore another is integrated with an external screw thread and can be taken out in installing hole by oil sealing very easily, and oil seal demounting and installation also can be improved oil sealing installation accuracy when maintenance by cigarette machinery equipment easily.
