Description
Technical field
The utility model belongs to floor spring field more particularly to a kind of high stability floor spring axle centre structure.
Background technique
The oil enveloping structure in the axle center of usual floor spring includes the bearing of the cover board on upper layer, lower layer, and oil sealing is and cover board and axis
Hydraulic oil seal circle that is coaxial and being set in axle center excircle is held, oil circuit sealing rings in the prior art are annular shape, and its
Any one place's radial section is circle.But due to having gap between cover board and axle center, inevitably have dust, gritty dust
End can fall at sealing ring by entering the gap, influence the sealing effect of oil sealing and can generate friction with axle center, reduce oil
Envelope, the axle center even service life of floor spring；In addition, existing rotation axis only passes through a bearing and the dynamic mating connection of shell,
The problems such as stability is poor, is easy displacement damage.
Utility model content
The utility model is for deficiency present in background technique, and a kind of high stability floor spring axle center knot provided
Structure.
A kind of high stability floor spring axle centre structure of the utility model, including rotation axis and cover board, the bottom of rotation axis
End is equipped with undergauge plug, and set is filled with pressure-loaded bearing on undergauge plug, above undergauge plug in rotation axis successively suit be fixed with it is convex
Wheel disc, first bearing, oil circuit sealing rings and cover board, the periphery of first bearing are placed in the sleeve block groove of cover board lower part, oil circuit
Sealing ring is placed in the circular groove in the middle part of cover board, and the ring week of the rotation axis at oil circuit sealing rings is equipped with card slot, oil circuit sealing rings
Inner circumferential be equipped with the strip that is used cooperatively with card slot.
As the preferred of the utility model, it is equipped with dust-proof seal ring between oil circuit sealing rings top rotation axis and cover board, prevents
The periphery of dirt sealing ring is equipped with raised line, is placed in the annular groove on cover board.
As the preferred of the utility model, the outside of cover board is evenly distributed with fixed screw hole.
As the preferred of the utility model, the section of card slot is equilateral triangle, and the section of strip is equilateral triangle.
A kind of high stability floor spring axle centre structure of the utility model, simple structure and reasonable design, structural stability
Height is offseted using the pressure-loaded bearing of undergauge plug bottom installation when installation and the interior bottom of shell, then lid and shell is passed through spiral shell
Bar is connected and fixed, and improves the stability of rotation axis, while also being changed to be sleeved between oil circuit sealing rings in existing apparatus and be turned
It on moving axis axis the drawbacks of poor sealing effect, in addition increases dust-proof seal ring and dust is avoided to enter in shell, promoted and use the longevity
Life.
