Elimination.Here, since plastic part 3 and plastic part 4 are slightly elastic, when use, can ensure the gap of Y-direction by installing
Minimum control is between above-mentioned size.
Plastic part 1 and plastic part 24 can be separately designed in Y-direction size is divided into 2 grades or 3 grades or more, you can to set
Multi gear size is counted, such as：Mono- grade of mono- grade of 6.0mm, 6.2mm, mono- grade of 6.4mm, etc., to match；It is also possible to difference
Color is distinguished.Plastic part 3 and plastic part 4 are selected according to the Y-direction cavity size of external slide rail 2 when use, can both have been selected identical
Class can also select different class.
4 or 6 or 8, etc. can usually be selected by eliminating the plastic part in Y-direction gap.
In addition, one top surface arcwall face 35 of plastic part and two top surface arcwall face 45 of plastic part are higher by the upper sliding rail vertical edge top in outside
Sliding rail vertical edge top surface 112 on face 122 and inside avoids being in direct contact for interior slide track component 1 and 2 inner wall of external slide rail, eliminates
The abnormal sound of automobile in the process of moving.
Referring to Fig. 7-Figure 13, this is the concrete structure and method that the utility model eliminates Z-direction gap.
Wherein：To bearing, once the distance between top surface 511 is h5 at bearing one 5 center；Under bearing 26 center to bearing two
The distance between top surface 611 is h4；The distance between top surface 731 is h6 on 73 center to idler wheel of slider roller；In roll wheel assembly 7
The heart to bearing 1 or the bicentric distance of bearing be h7；On external slide rail inner wall under top surface 23 and external slide rail inner wall between top surface 24
Distance be H2.
Z-direction gap refers to：The shifting amount of interior slide track component 1 and external slide rail 2 in Z-direction.In the present embodiment, Z-direction
Gap=h4 or h5+h6+h7-H2, wherein：H4=h5 belongs to as long as Z-direction gap is less than 0.2mm and eliminates gap.
The utility model equally can make Z-direction have one in this way by the clearance control of the Z-direction between 0.1-0.2mm
Point point interference, does not interfere with the rotation or rolling of bearing assembly 1, bearing assembly 26 and roll wheel assembly 7.Concrete structure and control
Method processed is as follows：One roll wheel assembly 7 is installed on the center of sliding rail assembly, and suitable etc. in 7 both sides of roll wheel assembly
Bearing assembly 1 and 6 bearing assemblies 26 are symmetrically installed on distance and position, they are located at interior slide track component 1 and external slide rail 2
Between." suitable equidistant position " mentioned here refers to：Interior slide track component 1 in long track is determined according to the size in compartment
Length, then again determine installation bearing assembly 1 and 6 bearing assemblies 26 specific location, as long as interior slide track component is determined
Specific location those skilled in the art of 1 length, bearing assembly 1 and 6 bearing assemblies 26 can be very by calculating or experience
It obtains soon.
The bearing assembly 1 of the utility model includes bearing 1, bearing axis 52 and bearing axis hole 53, bearing 1 and axis
It holds axis 52 by bearing axis hole 53 to coordinate, they are structure as a whole；In the present embodiment, it is 17- that bearing 1, which selects outer diameter,
The closed bearing of 21mm, by riveting or being weldingly fixed on sliding rail vertical edge on the upper sliding rail vertical edge lateral surface 111 in inside and outside
On lateral surface 121.
Bearing assembly 26 is identical with the structure of bearing assembly 1, is not repeated.
The roll wheel assembly 7 of the utility model includes idler wheel rivet 71, rolling wheel support 72 and slider roller 73, idler wheel rivet 71
It is molded with 73 cold pier of slider roller, 72 punch forming of rolling wheel support.Wherein：Idler wheel rivet 71 includes the big step being connected
711 and small stair 712, bracket holes 721 are provided on rolling wheel support 72, and the center of slider roller 73 is provided with slider roller hole 731, branch
Frame aperture 721 is fixed with small stair 712 with riveting is merged, slider roller hole 731 and 711 clearance fit of big step pass through idler wheel
Slider roller 73 is riveted on rolling wheel support 72 by rivet 71.After installation, idler wheel rivet 71 is fixed with rolling wheel support 72, idler wheel riveting
The head of nail 71 forms manufactured head 7121；Due to there is an idler wheel gap 70 between rolling wheel support 72 and slider roller 73 so that sliding
Dynamic idler wheel 73 can facilitate rolling on idler wheel rivet 71.
In the present embodiment, roll wheel assembly 7 is fixed by welding in the interior sliding rail on sliding rail vertical edge lateral surface 111 on inside
In central recess 113.Meanwhile the welding position by adjusting roll wheel assembly 7 on inside on sliding rail 11, it is ensured that in bearing 1
To bearing, once the distance between top surface 511 h4 or 26 center of bearing add the heart to the distance between two times top surfaces of bearing 611 h4
The distance between top surface 731 h6 is plus 7 center of roll wheel assembly to bearing 1 or bearing two on 73 center to idler wheel of slider roller
The distance h7 at center subtracts the distance between top surface 23 and top surface 24 under external slide rail inner wall H2 on external slide rail inner wall（That is h5 or h4+
h6+h7-H2）Control is between 0.1-0.2mm, to ensure that the gap of Z-direction is eliminated.
2 or 4 or 6, etc. can usually be selected to the roll wheel assembly 7 in gap by eliminating Z.According to external slide rail inner wall
The distance between top surface 24 H2 determines that roll wheel assembly 7 is welded on interior slide track component 1 under upper top surface 23 and external slide rail inner wall
Position, and Z-direction gap is eliminated together with bearing assembly 1 and 6 bearing assemblies 26, namely：Top surface 23 passes through on external slide rail inner wall
The contact of top surface 731 ensures on idler wheel in roll wheel assembly 7, and top surface 24 then passes through bearing assembly 1 under external slide rail inner wall
Ensure with the contact of the once two times top surfaces in top surface 511 and bearing 611 of the bearing in 6 bearing assemblies 26, thus can combine and disappear
Except Z-direction gap.
Interior sliding rail central recess 113, interior sliding rail bearing hole 114 are also provided with by punching press on the interior slide track component 1 of the present invention
With interior sliding rail plastic part groove 115, sliding rail plastic part groove 115, which is located at, in one pair is located at sliding rail bearing hole 114 in one pair
Outside.In use, the manufactured head 7121 in roll wheel assembly 7 is placed into interior sliding rail central recess 113, the manufactured head 7121 is not
External slide rail 2 can be encountered, otherwise can generate interference with external slide rail 2；Bearing assembly 1 is assembled in interior sliding rail bearing hole 114（Bearing
Component 26 is similarly）, plastic part 1 and plastic part 24 are assembled in interior sliding rail plastic part groove 115.
