SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a reciprocating shaft leak protection oil guide assembly to solve the not enough of above-mentioned background art existence.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a novel reciprocating shaft leak protection oil guide assembly, includes the reciprocating shaft, the epaxial axle sleeve that is equipped with the area oil return hole of reciprocating, the tip fixed connection leak protection oil of axle sleeve covers thoroughly, be equipped with the recess of two circles of parallels in the cover thoroughly, two circles be equipped with the Y type oil blanket of two reverse installations in the recess respectively, recess in the cover thoroughly coincide with the cross-section that corresponds the Y type oil blanket of installation.
And furthermore, a reinforcing rib is arranged between the two reversely-installed Y-shaped oil seals and isolates the two Y-shaped oil seals.
Further, the width of the reinforcing rib between the two Y-shaped oil seals is 1-10 mm.
Furthermore, a 0-shaped ring is further arranged at the joint of the transparent cover and the shaft sleeve.
Furthermore, the diameter of the inner hole of the transparent cover is 0.5-3mm larger than that of the shaft.
Compared with the prior art, the utility model discloses an at least including following beneficial effect:
the utility model redesigns the structure of the inner cavity of the transparent cover, installs two Y-shaped oil seals, and arranges a reinforcing rib between the two Y-shaped oil seals, the reinforcing rib can play the role of supporting the oil seal, and can separate the two Y-shaped oil seals, thereby effectively preventing the leakage of oil liquid and having stronger sealing effect; the diameter of the inner hole of the transparent cover is slightly larger than that of the shaft, so that extra resistance is increased when the shaft does reciprocating motion. The diameter of the inner hole of the transparent cover is larger than the diameter of the shaft by 1mm, a double-Y-shaped oil seal reverse installation mode is adopted, bidirectional sealing can be realized, oil in the transparent cover is blocked to leak outwards, external dust is blocked inwards, and the problem that an original skeleton oil seal leaks oil easily is solved.
Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention.
