Embodiment
The utility model structure is described in detail below in conjunction with the accompanying drawings.
A kind of damper groove fastening seal structure of the utility model as shown in Figure 1, 2, by axis pin 1, supporting sleeve 2, groove
End cap 3, boss nut 4, T-shaped sealing ring cover 5 and steel pin 6 form.
Lifting lug hole axle of the axis pin 1 through the lifting lug hole of balance arm and damper is held interior.
Supporting sleeve 2 is located between the lifting lug hole end surface of balance arm and the lifting lug hole bearing face of damper, subtracts for adjusting
The gap to shake between device and side deck.
T-shaped sealing ring cover 5 is located at the sealing ring periphery of bearing.
The oscillating bearing sealing ring cover used at present is unfixed, if installing tension in assembling, easily causes sealing
Circle extruding tension influences oscillating bearing swinging；Also need to ensure that slotted nut 4 tightens length, while avoid at the top of damper axis pin
Screw thread is nearer apart from side deck.The characteristics of according to oscillating bearing, the utility model is using following specific limiting structure：
First：Boss nut coordinates with groove end cap, axis pin screw top and side deck spacing bigger.
Groove end cap 3 is located at the pin shaft thread periphery of nearside deck one end of axis pin 1, positioned at the bearing right end of damper；
Bearing progress to damper is spacing.
Boss nut 4 and groove end cap 3 are located at pin shaft thread end periphery；3 right side of groove end cap has groove, can make
The groove of left side " retraction " groove end cap of boss nut 4 is obtained, shortens groove end cap covering pin shaft thread, can shorten
In the case of pin shaft thread total length, ensure that the length of fit of boss nut 4 and pin shaft thread is constant.Groove end cap and boss spiral shell
Mother coordinates depth.
Second：Have between T-shaped sealing ring cover and groove end cap at regular intervals.
The section of T-shaped sealing ring cover 5 to be T-shaped, T-shaped sealing ring cover 5 " T-shaped vertical portion " positioned at sealing ring periphery and
It is spacing with that can be formed in the assembling process of T-shaped sealing ring cover 5 in damper lifting lug between damper lifting lug；" T-shaped level
Part " is located at the end of sealing ring, and T-shaped sealing ring cover 5 fixes fitting depth, ensures the sealing ring installation pine in sealing ring cover
Tightly meet the requirements.
The T-shaped vertical portion of T-shaped sealing ring cover 5 is slightly larger than the axial length of sealing ring.Can be to avoid the mistake of sealing ring
Oscillating bearing rotates dumb caused by degree compresses.
3 periphery of groove end cap have flange positioned at it is T-shaped sealing 5 right end of ring cover, can restricted T type sealing ring cover 5 slide
Go out, and it is at regular intervals with T-shaped sealing ring cover right end tool, the spacing between the flange and T-shaped sealing ring cover 5 ensures damper spirit
It is living to swing, limit the swingable angular range of oscillating bearing.
Wherein, T-shaped sealing ring cover 5 is pressed in damper lifting lug by interference fit；Boss nut 4 screws in the screw thread of axis pin
Part, compressed grooves end cap 3 fasten damper, the groove insertion steel pin 6 on other end boss nut, and steel pin 6 is same
When be inserted into boss nut on groove and axis pin on hole so that damper is fixed on axis pin.
Coordinated by groove end cap and boss nut, ensure can fastening thread length it is nondecreasing in the case of, increase pin
Spacing at the top of axis between vehicle side deck, avoids the damper fastening caused by hypotelorism between screw thread and side deck from losing
Effect；On the other hand T-shaped sealing ring cover is formed spacing with groove end cap flange (flange), it is ensured that damper has enough swing skies
Between, at the same swing it is excessive when formed it is spacing.
This device is designed using concave station type, is improved the mode that usually used nut plane compresses end cap, is passed through bumps
Platform plane is compressed, and the reach of growth improves the fastening reliability of damper；Improved T-shaped sealing ring cover, has
Effect avoids sealing ring pressing tension, while sealing fastening gap can be formed with the flange of groove end cap, and it is close to improve fastening
Envelope ability.
