Rational in infrastructure, excellent in use effect after this scheme of adoption.
Description
Technical Field
The utility model belongs to the technical field of the sealed technique of shafting and specifically relates to indicate the sealed wear-resisting lock sleeve of bipyramid of usefulness of shafting.
Background
The inner part of the existing shaft system locking union cap is in a straight cylinder shape, and an oil seal is easy to lock and slide out of the outer end of the union cap after being sleeved.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provide a bipyramid wear-resistant locking sleeve which is reasonable in structure and good in using effect and is used for shaft system sealing.
In order to achieve the above object, the present invention provides a technical solution: the double-cone wear-resistant locking sleeve for sealing the shafting comprises a sleeve body, wherein one end of the sleeve body forms a cylindrical transition end, the peripheral surface of the other end of the sleeve body forms a conical sealing end, a connecting internal thread is arranged on the wall of an inner cavity of the transition end, a first sealing step and a second sealing step are arranged on the wall of the inner cavity of the sealing end, the diameter of the first sealing step is larger than that of the second sealing step, the first sealing step is positioned on one side of the internal thread, and the outer end of the second sealing step is expanded to form a sealing groove.
The inner cavity wall of the first sealing step is conical, and the inner cavity wall of the second sealing step is cylindrical.
The taper of the first sealing step is smaller than that of the peripheral surface of the sealing end.
The cross section of the sealing groove is C-shaped, and the sealing groove is positioned at the end part of the sealing end.
The outer peripheral surface of the end part of the transition end is provided with three positioning grooves which are distributed on the outer peripheral surface of the transition end in equal parts.
After adopting the above scheme, the utility model, the transition end is used for connecting the copper sheathing, the oil blanket surface is established into the toper, the oil blanket inserts from the transition end, it is spacing with the contact formation of first sealed step inner chamber wall to insert back toper locking oil blanket outer peripheral face, the sealed step suit of second is on the shafting outer peripheral face, the seal groove is used for clamping outside sealing ring, the constant head tank is used for fixing a position wear-resisting cover, through the seal groove, the locking to toper locking oil blanket is accomplished to first sealed step, the locking back oil blanket can only slide to the copper sheathing direction, and can not slide to locking and cap outer end, the toper of seal end outer peripheral face is used for cooperating with outside oil blanket and cap, it is rational in infrastructure, excellent.
