Abstract
The invention discloses a kind of high leakproofness rotary decelerators, including base and cover plate, sealing ring is equipped between the base and cover plate, it is correspondingly provided with annular groove on the base and cover plate, the interior outside periphery and annular groove medial surface of the sealing ring are bonded, and annular groove bottom surface is equipped with several bored holes, and bored hole is orthogonal with annular groove, it is equipped with support plate in the bored hole, elastic supporting bar is equipped between support plate and bored hole bottom surface.It is of the invention novel in design, it is simple and reasonable, the sealing ring tightness being embedded in annular groove is high, after sealing ring aging deformation, under the elastic force effect of elastic supporting bar, support plate in base and cover plate tightly clips sealing ring, so that sealing ring is continued the intersection for being tightly filled in base and cover plate, keeps good leakproofness.
Description
Technical field
The present invention relates to rotary decelerators, more particularly, to a kind of high leakproofness rotary decelerator.
Background technology
Rotary decelerator, using pivoting support（It is commonly called as turntable）As retarder driven part, it can be achieved that unconfined circle
Zhou Huizhuan and deceleration, can bear larger axial force, radial load and power of toppling, this kind of device can be fabricated to standard mechanical portion
For part thus applied on the various mechanical equipments for having rotation to require, especially such retarder is high, compact-sized with precision, carries
The big advantage of ability is suitble to use under more severe work condition environment.It is provided with engagement in the pedestal of rotary decelerator
Pivoting support and worm screw are arranged sealing ring in the prior art generally between cover board and pedestal and seal then by cover closure,
Sealing ring after prolonged use may aging deformation, leakproofness is deteriorated, causes in pedestal for lubricating pivoting support and snail
The oil leak of bar influences the normal use of rotary decelerator.
Invention content
The present invention is above-mentioned in order to overcome the shortcomings of, provides a kind of high leakproofness rotary decelerator, including base and cover
Plate is equipped with sealing ring between the base and cover plate, annular groove is correspondingly provided on the base and cover plate, the sealing ring
Interior outside periphery and the fitting of annular groove medial surface, annular groove bottom surface are equipped with several bored holes, and bored hole and annular groove are just
It hands over, support plate is equipped in the bored hole, elastic supporting bar is equipped between support plate and bored hole bottom surface.
Preferably, the elastic supporting bar is metallic rod.
Preferably, the elastic supporting bar is welded and fixed with bored hole bottom surface, support plate respectively.
Preferably, the bored hole number is 12-20, and rational bored hole number keeps resilient support distance between tie rods reasonable, to
The support force interval that sealing ring is subject to is reasonable.
The beneficial effects of the invention are as follows：It is of the invention novel in design, simple and reasonable, the sealing being embedded in annular groove
It is high to enclose leakproofness, after sealing ring aging deformation, under the elastic force effect of elastic supporting bar, the support plate in base and cover plate is tightly
Sealing ring is clipped, so that sealing ring is continued the intersection for being tightly filled in base and cover plate, keeps good leakproofness, avoid result in
Oil leak in pedestal for lubricating pivoting support and worm screw avoids the normal use for influencing rotary decelerator.
Description of the drawings
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein：
Fig. 1 is the appearance diagram of the present invention；
Fig. 2 is the structural schematic diagram of the present invention；
Fig. 3 is the cutting plane schematic diagram of A-A in Fig. 1.
Specific implementation mode
In conjunction with the accompanying drawings, the present invention is further explained in detail.These attached drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the present invention, therefore it only shows the composition relevant to the invention.
As shown in Figs. 1-3, the present invention is a kind of high leakproofness rotary decelerator, including pedestal 1 and cover board 2, the base
Be equipped with sealing ring 3 between seat 1 and cover board 2, be correspondingly provided with annular groove 4 on the pedestal 1 and cover board 2, the sealing ring 3 it is interior
Outer circumference face and the fitting of 4 medial surface of annular groove, 4 bottom surface of annular groove are equipped with several bored holes 5, bored hole 5 and annular groove 4
It is orthogonal, it is equipped with support plate 6 in the bored hole 5, elastic supporting bar 7 is equipped between 5 bottom surface of support plate 6 and bored hole.
The elastic supporting bar 7 is metallic rod.
The elastic supporting bar 7 is welded and fixed with 5 bottom surface of bored hole, support plate 6 respectively.
5 quantity of bored hole is 12-20.
Of the invention novel in design, simple and reasonable, the sealing ring tightness being embedded in annular groove is high, and sealing ring is old
After changing deformation, under the elastic force effect of elastic supporting bar, the support plate in base and cover plate tightly clips sealing ring, makes sealing ring
Continue the intersection for being tightly filled in base and cover plate, keep good leakproofness, avoids result in pedestal for lubricating revolution
The oil leak of bearing and worm screw avoids the normal use for influencing rotary decelerator.
It is above-mentioned according to the present invention be enlightenment, through the above description, relevant staff completely can without departing from
In the range of this invention technological thought, various changes and amendments are carried out.The technical scope of this invention is not limited to
In the content on specification, it is necessary to determine its technical scope according to right.
