Compared with the prior art, the utility model discloses the pivot is more stable, and bearing capacity is stronger, and life is longer.
Description
Technical field
This utility model relates to automobile-used utensil, particularly to a kind of rotating train seat axle.
Background technology
Existing train seat is designed to underframe and pivoted frame two parts, and underframe is fixed on compartment terrace, pivoted frame
Realize making 180 degree of rotations on underframe by a rotating shaft.
The rotating shaft being fixed on pivoted frame is inserted in the Self-lubricating bearing bush on underframe, connects with round nut.So
Connected mode rotating shaft unstable, bearing capacity is little.
Utility model content
The purpose of this utility model is to provide a kind of rotating train seat axle, this rotating train seat axle rotating shaft
More stable, bearing capacity is higher, and service life is longer.
Technical scheme is: a kind of rotating train seat axle, described rotating train seat axle include plane bearing,
Middle armrest support, the axle that is rotatably connected, rotation stull and rolling bearing；It is provided with installation in described rotation stull
Hole, rolling bearing is arranged in this installing hole, and described plane bearing is arranged on above rolling bearing, described rolling
Dynamic bearing and the alignment of plane bearing central hole；The described axle that is rotatably connected is connected on middle armrest support, rotates
Connecting shaft is each passed through plane bearing, rolling bearing and rotation stull.
As preferably, described rolling bearing is needle bearing, or the bearing that deeply hooks, or taper roll bearing.
As preferably, described rotating train seat axle also includes that bearing holder (housing, cover), described bearing holder (housing, cover) are enclosed within rolling bearing
On outer surface.
As preferably, described rotating train seat axle also includes that stop washer, described stop washer are connected to institute
State the shaft end that is rotatably connected.
As preferably, described rotating train seat axle also includes that rotating shaft packing ring, described rotating shaft packing ring are connected to institute
State the shaft end that is rotatably connected.
As preferably, described rotating train seat axle also includes that round nut, described round nut are connected to described rotation
Turn connecting shaft end.
Compared with prior art, the beneficial effects of the utility model are:
This utility model rotating shaft is more stable, and bearing capacity is higher, and service life is longer.
Accompanying drawing explanation
Fig. 1 is this utility model decomposition texture schematic diagram；
Fig. 2 is this utility model connecting portion sectional view schematic diagram；
Fig. 3 is this utility model lower support structure schematic diagram；
Fig. 4 is this utility model upper support structure schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Such as Fig. 1-4, a kind of rotating train seat axle, including plane bearing 1, middle armrest support 2, rotate even
Spindle 3, rotation stull 4, rolling bearing 6, stop washer 7, rotating shaft packing ring 8, round nut 9 and bearing
Set 11.Rolling bearing 6 is that needle bearing is more excellent, more preferable for deep hook bearing.Bearing holder (housing, cover) 11 is enclosed within rolling
On bearing 6 outer surface.
Rotating and be provided with installing hole in stull 4, rolling bearing 6 is arranged in this installing hole.Plane bearing 1
It is arranged on above rolling bearing 6.
The axle 3 that is rotatably connected is connected on middle armrest support 2, and middle armrest support 2 is fixed in support 10,
Rotate stull 4 to be fixed in lower support 5.
Rolling bearing 6 is arranged in rotation stull 4, rolling bearing 6 and the alignment of plane bearing 1 central hole,
The axle 3 that is rotatably connected is each passed through plane bearing 1, rolling bearing 6, rotates stull 4 and lower support 5.Rotating shaft
Packing ring 8, stop washer 7, round nut 9 are connected to axle 3 end that is rotatably connected.
This utility model rotating train seat axle is arranged between support 10 and lower support 5.
During assembling, the axle 3 that is rotatably connected is connected on the middle armrest support 2 in upper support 10, in
Armrest support 2 is fixed in support 10, rotates stull 4 and is fixed in lower support 5.First by bearing holder (housing, cover)
11 are arranged in rotation stull 4, are then arranged in bearing holder (housing, cover) 11 by the bearing 6 that deeply hooks, it is ensured that center
Perforation alignment, the axle 3 that finally will be rotatably connected passes plane bearing 1, deep hook bearing 6, rotates stull 4
And lower support 5, and twist with rotating shaft packing ring 8, stop washer 7 and round nut 9 axle 3 end that will be rotatably connected
Tightly.
During use, this utility model uses " rolling bearing+plane bearing " connected mode, and rotating shaft is more stable,
Bearing capacity is higher.When using deep hook bearing, rotating shaft is more preferable than using needle bearing stability, the life-span
Longer.
