Specific embodiment
Following is a specific embodiment of the present invention in conjunction with the accompanying drawings, technical scheme of the present invention will be further described,
However, the present invention is not limited to these examples.
As depicted in figs. 1 and 2, a kind of durable type sleeve of the present invention, including interior empty straight-through external member ontology 100, the set
It is penetrated through before and after part ontology 100.
Threaded portion 110 is offered on one end outer surface of external member ontology 100, the other end of external member ontology 100 is axially arranged
There is prismoid section 120 and the prismoid section 120 has the vertex of a cone 121 and cone bottom 122, offers on the external member ontology 100 through external member
The notch 130 of ontology 100 offers symmetrically arranged first fuel feed hole 140 and the second fuel feed hole on the external member ontology 100
150, first fuel feed hole 140 and the second fuel feed hole 150 are axially extending from the end of thread to prismoid section 120 and terminate in prismoid section
On 120, the first main oil groove 123 is laterally offered on 120 outer surface of prismoid section and the first main oil groove 123 and the first fuel feed hole 140
It communicates, several first point of oil groove communicated with the first main oil groove 123, prismoid section 120 is axially offered on 120 outer surface of prismoid section
The second main oil groove 124 is laterally offered on inner surface and the second main oil groove 124 is communicated with the second fuel feed hole 150, in prismoid section 120
Several second point of oil groove 125 communicated with the second main oil groove 124, the cone bottom 122 and threaded portion 110 are axially offered on surface
It is connected.
This sleeve using the above structure, opens up the first fuel feed hole 140 and the second fuel feed hole 150 simultaneously on sleeve,
The first main oil groove 123 and several first point of oil groove, the first main oil groove 123 and the first fuel feed hole are opened up on the outer surface of tightening energy
140 communicate, and the second main oil groove 124 and several second point of oil groove 125, the second main oil groove 124 are opened up on the inner surface of sleeve
It is communicated with the second fuel feed hole 150, oiling, oil liquid is carried out to the first fuel feed hole 140 and the second fuel feed hole 150 before bearing installation
It is had respectively entered in first point of oil groove and second point of oil groove 125 through the first main oil groove 123 and the second main oil groove 124, passes through first
Divide oil groove and second point of oil groove 125 to make between sleeve and bearing, adequately lubricated between sleeve and axis, reduces tightening
Resistance when moving between bearing and axis is covered, when being easily installed bearing, be more convenient, is more labor-saving, and shortening installation
Between, and sleeve is made to be effectively protected, no damage is also conducive to disassembly, is used multiple times.
Meanwhile first fuel feed hole 140 and the second fuel feed hole 150 respectively lead to the first main oil groove 123 of sleeve outer surface
With the second main oil groove 124 of sleeve inner surface, enable the surfaces externally and internally of sleeve oiling simultaneously, sleeve within the same time
It can be lubricated simultaneously in a relatively short period of time between axis, between sleeve and bearing, shorten the time of oil inlet, effectively
The set-up time of bearing is shortened, if the first main oil groove 123 and 124, the second main oil groove pass through a fuel feed hole oil inlet, oil
Liquid stream not only requires oil pressure to different both directions, but also oil stream to be made to enter first point of oil groove and second point of oil groove
125, it takes a long time, therefore, extends the set-up time of bearing.
The cone bottom 122 of sleeve is connected with threaded portion 110, effective to increase since cone 122 segment thickness of bottom is larger
The intensity of threaded portion 110, prevents the damage when installing bearing of threaded portion 110, extends the service life of entire sleeve.
Further, it is provided on external member ontology 100 and is communicated respectively with the first fuel feed hole 140 and the first main oil groove 123
And first connecting hole 141 vertical with the first fuel feed hole 140,141 aperture of the first connecting hole is less than 140 hole of the first fuel feed hole
Diameter is provided on the external member ontology 100 and communicates respectively with the second fuel feed hole 150 and the second main oil groove 124 and with second
Vertical second connecting hole 151 of fuel feed hole 150,151 aperture of the second connecting hole is less than 150 aperture of the second fuel feed hole.
First connecting hole, 141 aperture is less than 140 aperture of the first fuel feed hole and perpendicular to the first fuel feed hole 140, the second connection
Less than 150 aperture of the second fuel feed hole and perpendicular to the second fuel feed hole 150, such design energy moment increases oil liquid in hole 151 aperture
Pressure, make the flowing velocity of oil liquid faster, thus, oil liquid can reach first point of oil groove and second point of oil groove 125 faster, tightly
Fixed set, bearing, axis three directly can comparatively fast be lubricated.
Further, first fuel feed hole 140 extends to prismoid section 120 and is formed with the first elongated hole 142, and described the
Two fuel feed holes 150 extend to prismoid section 120 and are formed with the second elongated hole 152, the first elongated hole 142 and the second elongated hole 152
When oil inlet starts first fuel feed hole 140 can be buffered with the second fuel feed hole 150, to prevent moment biggish pressure will be into
The oil liquid entered in the first fuel feed hole 140 and the second fuel feed hole 150 reversely sprays.
Further, it is formed with annular groove 160 between the threaded portion 110 and cone bottom 122, when bearing is installed to axis
When afterwards or bearing needs to dismantle, sleeve requires to disassemble between bearing and axis, and sleeve and axis and bearing it
Between power it is larger, the setting of the annular groove 160 so that sleeve disassembly when, have the impetus of a transverse direction, facilitate sleeve
Disassembly.
Specific embodiment described herein is only an example for the spirit of the invention.The neck of technology belonging to the present invention
The technical staff in domain can make various modifications or additions to the described embodiments or replace by a similar method
In generation, however, it does not deviate from the spirit of the invention or beyond the scope of the appended claims.
