Abstract
The utility model discloses a kind of screw locking structures applied to rubber pad vibration damping, belong to engineering machinery connection structure field.It includes bolt and rubber pad, the rubber pad is located between connected piece and mounting seat, the bolt passes through connected piece, rubber pad and is fixed in mounting seat, further include the washer and steel bushing being sleeved on bolt, the steel bushing is located between washer and mounting seat, the steel bushing and washer and mounting seat rigid contact.Vibration damping of the utility model for Engineering Machinery Components connects, both the Elastic Contact that ensure that connected piece and rubber pad has effectiveness in vibration suppression, while in turn ensuring the rigid connection of bolt, make it pretightning force will not be caused to disappear because of the plastic deformation of rubber pad, plays good anti-loosing effect.
Description
Technical field
The utility model belongs to a kind of connection structure, specifically, more particularly to a kind of spiral shell applied to rubber pad vibration damping
Bolt anti-loose structure.
Background technology
Engineer machinery operation operating mode is complicated severe, and the impact and vibration when overall operation are larger, therefore most of parts
It is required for considering the elastic connection way with effectiveness in vibration suppression when installation designing, to improve its reliability.Rubber shock-absorbing pad with
Its low cost, installation is simple, reliability is high and becomes the preferred manner of most parts vibration dampings.However, rubber pad vibration damping is also deposited
In certain hidden danger, it is exactly wherein critically important one that wherein fastening bolt, which loosens,.Current most of main engine plants are locking by smearing
Glue avoids loosening, however effect and bad.It searches to the bottom reason, after being ageing of rubber, elasticity is deteriorated, and gradually generates plasticity
Deformation, pretightning force when bolt fastens fades away, so as to cause bolt looseness, even if smearing locking glue effect in this case
Also bad.
Utility model content
The utility model aim is to provide a kind of screw locking structure applied to rubber pad vibration damping, to overcome the prior art
The screw locking structure of middle rubber pad vibration damping is after ageing of rubber, and pretightning force when bolt fastens fades away, so as to cause spiral shell
The defect that bolt loosens.
The utility model is realized using following technical scheme：
Screw locking structure described in the utility model applied to rubber pad vibration damping, including bolt and rubber pad, it is described
Rubber pad is located between connected piece and mounting seat, and the bolt passes through connected piece, rubber pad and is fixed on mounting seat
On, further include the washer and steel bushing being sleeved on bolt, the steel bushing is located between washer and mounting seat, the steel bushing and washer
And mounting seat rigid contact.
The diameter of bore of the washer is less than the outside diameter of steel bushing.
The steel bushing height dimension is less than connected piece thickness plus the sum of rubber pad nature thickness, and greatly
The sum of size after connected piece thickness is plus rubber pad compression.
Compared with prior art, the utility model has the beneficial effects that：
The utility model is simple in structure, both ensure that the Elastic Contact of connected piece and rubber pad, has effectiveness in vibration suppression, together
When in turn ensure the rigid connection of bolt, make it pretightning force will not be caused to disappear because of the plastic deformation of rubber pad, play good
Good anti-loosing effect.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
In figure：1, bolt；2, washer；3, steel bushing；4, connected piece；5, rubber pad；6, mounting seat.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, the screw locking structure described in the utility model applied to rubber pad vibration damping, including bolt 1, rubber
Rubber cushion 5, washer 2 and steel bushing 3, between connected piece 4 and mounting seat 6, bolt 1 passes through to be connected 5 fixed clamp of rubber pad
Part 4, rubber pad 5 are simultaneously fixed in mounting seat 6, and steel bushing 3 is located between washer 2 and mounting seat 6, and steel bushing 3 and pad
Circle 2 and 6 rigid contact of mounting seat.
Preferably, washer 2 is detached from steel bushing 3 and keeps steel bushing 3 and 6 rigid contact of washer 2 and mounting seat in order to prevent,
The diameter of bore of washer 2 is less than the outside diameter of steel bushing 3.
Preferably, in order to ensure the Elastic Contact before bolt 1 is tightened between connected piece 4 and rubber pad 5, and in rubber
Rigid contact can be generated when the compression of pad 5 generates pretightning force between washer 2 and steel bushing 3,3 height dimension of steel bushing is less than connected piece
4 thickness are compressed plus the sum of natural thickness of rubber pad 5, and more than 4 thickness of connected piece plus rubber pad 5
The sum of size afterwards.
The operation principle of the utility model：During bolt 1 is tightened, connected piece 4 and rubber pad 5 ensure that first
Between Elastic Contact, generate rigidity with the elastic compression of the precession and rubber pad 5 of bolt 1, between washer 2 and steel bushing 3 and connect
It touches, bolt 1 ensure that 1 pretightning force of bolt after reaching specified screw-down torque.Aging with rubber pad 5 and Repeated Compression, gradually
Plastic deformation is generated, but does not influence the rigid contact between bolt 1 and washer 2, steel bushing 3, mounting seat 6, therefore is had no effect on
Pretightning force, to reach anti-loosing effect.
