Abstract
The utility model provides a kind of bearing of double nut vertical pulling lock sleeve；The bearing makes fastening nut move along a straight line to the right by rotation left-handed screw, and sleeve is pulled to move in the same direction, inside enclasping force is generated, simply bearing is locked on axis, cooperation stress is more evenly, the circularity for more conducively guaranteeing bearing, avoids the damage of bearing, improves the service life of bearing；In addition, the design bearing is reasonable, structure is simple, any type of bearing is suitble to use, when installation only needs an allen wrench, and convenient disassembly is suitble to promote the use of.
Description
Technical field
The utility model relates to a kind of bearings of double nut vertical pulling lock sleeve, belong to technical field of bearings.
Background technique
In bearing industry, the pattern of bearing is varied, the fixed form between bearing and axis also there are many, various axis
Holding the fixed form between axis has its different construction and feature.The tightening jacket stationary type having had currently on the market be by
Adapter assembly is put between bearing inner race and axis, when fixing bearing, is tightened the locking nut on sleeve, is made bearing bore diameter
The outer conical surface of circular conical surface and tightly fixed liner is in close contact, to bearing is fixed on axis, although this fixed form can change
Concentric deterioration between kind bearing and axis, still, for locking nut while fastening, sleeve can generate one to bearing inner race
Pulling force after long-time, can make the rotary part of Bearing inner generate offset, influence the function of bearing, and that shortens bearing uses the longevity
Life.Moreover, being to have more an indirect sleeve between bearing taper hole and axis, the uncertainty of cooperation situation is increased.
There are also some novel bearing fixed forms, such as: concentric ring fixed form；Concentric ring fixed form is in bearing
Inner ring side is equipped with the concentric ring concentric with inner ring, is provided with lock screw on the concentric ring, which is exposed in bearing
Seat is outer, when fastening, tightens lock screw, an opposite effect power can be generated between such concentric ring and axis and becomes concentric ring
Shape, so that bearing is fixed on axis, when using above-mentioned fixed form come fixing bearing, and be easy to cause axis and bearing it
Between deteriorate with one heart, not only disassembly is difficult, but also can damage bearing, shortens the service life of axis.
Utility model content
A kind of bearing of double nut vertical pulling lock sleeve is provided purpose of the utility model is to solve the above problem；
The bearing makes fastening nut move along a straight line to the right by rotation left-handed screw, and sleeve is pulled to move in the same direction, generates inside embrace
Clamp force is simply locked in bearing on axis, and cooperation stress more evenly, more conducively guarantees the circularity of bearing, avoids bearing
Damage, improves the service life of bearing；In addition, the design bearing is reasonable, structure is simple, any type of bearing is suitble to make
An allen wrench is only needed when with, installation, convenient disassembly is suitble to promote the use of.
In order to achieve the above object, the utility model is realized by following technological means.
A kind of bearing of double nut vertical pulling lock sleeve, it is characterized in that: including inner ring, outer ring, roller, sleeve, fixed spiral shell
Mother, left-handed screw, fastening nut, the inner ring internal diameter are the taper holes with taper, are provided with sleeve, sleeve on the inside of inner ring
Outer diameter band is tapered, and identical as inner ring internal diameter taper, and inner ring outer diameter one end is provided with screw thread, is provided on inner ring outer diameter outer
Circle, roller, inner ring one end is fixed together by screw thread and fixture nut.
The fixture nut is connected by several left-handed screws with fastening nut.
The fastening nut is intermeshed by internal screw thread and the external screw thread of sleeve one end.
The utility model mainly has the advantages that
1, the bearing makes fastening nut move along a straight line to the right by rotation left-handed screw, and sleeve is pulled to move in the same direction, produces
Raw inside enclasping force, is simply locked in bearing on axis, and cooperation stress more evenly, more conducively guarantees the circularity of bearing, keeps away
The damage for having exempted from bearing improves the service life of bearing.
2, the design bearing is reasonable, structure is simple, and any type of bearing is suitble to use, and when installation only needs six in one
Angle spanner, convenient disassembly are suitble to promote the use of.
Detailed description of the invention
Fig. 1 is a kind of the schematic diagram of the section structure of the bearing of double nut vertical pulling lock sleeve of the utility model.
Fig. 2 is a kind of side structure schematic view of the bearing of double nut vertical pulling lock sleeve of the utility model.
Main element symbol description:
1 bearing inner race
2 outer rings
3 rollers
4 sleeves
5 fixture nuts
6 left-handed screws
7 fastening nuts
Below with reference to example and Figure of description, the utility model is described in further detail:
Specific embodiment
Embodiment
As Figure 1-Figure 2, a kind of bearing of double nut vertical pulling lock sleeve, it is characterized in that: including inner ring 1, outer ring 2, rolling
Sub 3, sleeve 4, fixture nut 5, left-handed screw 6, fastening nut 7,1 internal diameter of inner ring is the taper hole with taper, inner ring 1
Inside is provided with sleeve 4, and 4 outer diameter band of sleeve is tapered, and identical as 1 internal diameter taper of inner ring, the setting of 1 outer diameter one end of inner ring
There is screw thread, outer ring 2, roller 3 are provided on 1 outer diameter of inner ring, 1 one end of inner ring is fixedly connected on one by screw thread and fixture nut 5
It rises.
The fixture nut 5 is connected by several left-handed screws 6 with fastening nut 7.
The fastening nut 7 is intermeshed by internal screw thread and the external screw thread of 4 one end of sleeve.
Bearing state is that bearing is shifted on axis, after axial position determines, is worn with allen wrench with sleeve entirety
The hole on fastening nut 7 is crossed, is inserted into the hexagon ring of left-handed screw 6, rotates to the right, then nut drives fastening nut 7 to the right
Mobile, sleeve 4 also moves right therewith, generates inward force F, is fixed on bearing on axis together with sleeve 4.Disassembly
When, left-handed screw 6 is reversely rotated with allen wrench, then fastening nut 7 drives sleeve 4 to be moved to the left release, removes rapidly
Bearing.
It should be understood that the above is only the preferred embodiment of the present invention, it is practical new cannot once to limit this
The practical range of type.Therefore, any modification, equivalent substitution and improvement made within the spirit and principle of the present invention
Deng should be included within the scope of protection of this utility model.
