Specific embodiment
It is described in further detail with reference to the accompanying drawing and by specific embodiment to utility model, following embodiment only describes
Property, it is not restrictive the protection scope of the utility model.
Embodiment
It is linear bearing in the prior art referring first to attached drawing 1, including outer ring 11 and internal ball 12 is set
With retainer 13, it is respectively arranged with sealing ring 14 at the both ends of outer ring 11, when with axis is closed, rolls and rubs between ball 12 and axis
It wipes, sealing sliding cooperation, prevents dust etc. from entering in outer ring 11 between sealing ring 14 and axis.This setup is not because storing up
Oily structure only immerses a small amount of lubricating oil in bearing, consumes quickly in use, the case where losing lubricating oil
Under, bearing can damage quickly.
In the present embodiment, the linear bearing with oil storage cabin 3, referring to attached drawing 2-8, linear bearing still includes outer ring 21, with
And the ball 22 and retainer 23 to set within it, and oil storage cabin 3 is respectively provided at the both ends of outer ring 21.3 court of oil storage cabin
It is docked between the side and outer ring 21 of outer ring 21 by clamping mechanism realization, oil storage cabin 3 deviates from a lateral edge oil storage of outer ring 21
The center of circle uniform intervals in storehouse 3 are provided with 4 shoe cream rooms 31, and are combined with sealing ring 24 in the side, when be packed into sealing ring 24 it
Afterwards, by there are the oil-through holes 32 towards 3 center of circle direction of oil storage cabin between shoe cream room 31 and sealing ring 24.Axis 6 is closed to work as to match
When, the lubricating oil or lubricating grease being stored in shoe cream room 31 can flow to axis 6 by oil-through hole 32, in the cooperation of axis 6 and bearing
In the process, lubrication protection layer is formed on the surface of axis 6, prevents that dry friction occurs between ball 22.Meanwhile sealing ring 24 is arranged
In side of the oil storage cabin 3 far from outer ring 21, and the two sides for being incorporated in outer ring 21 are both provided with the characteristic of oil storage cabin 3, Ke Yijin
Amount increases it and uses effective time cycle for a long time by lubricating grease or lubrication oil seal within linear bearing.
In order to further increase the storage time of lubricating oil or lubricating grease, oil storage pad can be set in shoe cream room 31
311, oil storage pad 311 can be the material of the big adsorption capacity in the small-bores such as sponge.
Clamping mechanism therein includes sliding block 4, is set as the sliding block 4 of 4 pieces of a quarter ring block forms herein.Sliding block 4
It can be slid along the radial direction of oil storage cabin 3, the side of sliding block 4 towards oil storage cabin 3 be provided with sliding connection block 43, in oil storage cabin
It is provided with the sliding slot 33 being radially arranged on 3, by the cooperation of sliding connection block 43 and sliding slot 33, realizes sliding block 4 along oil storage
Storehouse 3 radially slides.And bullet is provided between a side bottom and sliding connection block 43 of the sliding slot 33 far from 3 center of circle of oil storage cabin
Spring 5, so that in the original state, spring 5 will drive sliding block 4 to slide towards 3 center of circle direction of oil storage cabin, so that sliding block 4 is in Fig. 7
Under state, a complete annular is formed.Meanwhile the one end in sliding block 4 towards 3 center of circle of oil storage cabin being provided with spherical 42, ball
The section chord length in shape face 42: action be 8~10:1, when sliding block 4 in a state of nature when, the spherical 42 is in linear bearing
Bearing hole in.To which when oil storage cabin 3 cooperates insertion axis 6, the end of axis 6 will be against on spherical surface, and spherical surface will be by along oil storage
The component of 3 radial direction of storehouse pushes sliding block 4 and slides away from the direction in 3 center of circle of oil storage cabin, the state in Fig. 8.It here will be spherical
The section chord length in face 42: action is set as 8~10: 1, can place when axis 6 is pressed on spherical 42, appearance can not promote
Stuck phenomenon.And after axis 6 completely extends across shoe cream room 31, it will be the point contact of spherical 42 Yu 6 face of axis, abrasion can be several
Disregard, the sliding of axis 6 will not be hindered.
To, when oil storage cabin 3 sticks on 21 both ends of outer ring and is passed through axis 6, axis 6 will by setting in sliding block 4 towards storage
The guiding mechanism of 3 center of circle side of bunker drives sliding block 4 to slide outward away from 3 center of circle direction of oil storage cabin, so that fixture block 41 is caught in card
Slot 211 realizes that the rigidity between oil storage cabin 3 and outer ring 21 is clamped, and can be avoided substantially de- between oil storage cabin 3 and outer ring 21
From, and after extracting axis 6 out, the natural disengaging disassembly being just able to achieve between oil storage cabin 3 and outer ring 21 is convenient for changing and changes lubrication
Oil.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
