Abstract
The utility model discloses a kind of high leakproofness rotary decelerators, including base and cover plate, sealing ring is equipped between the base and cover plate, annular groove is correspondingly provided 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.The utility model is 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 utility model relates to rotary decelerators, more particularly, to a kind of high leakproofness rotary decelerator.
Background technique
Rotary decelerator is used as retarder driven part, it can be achieved that unconfined circle using pivoting support (being commonly called as turntable)
Zhou Huizhuan and deceleration, can bear biggish axial force, radial force and power of toppling, this kind of device can be fabricated to standard mechanical portion
For part to be 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.Engagement is provided 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.
Utility model content
The utility model is above-mentioned in order to overcome the shortcomings of, provides a kind of high leakproofness rotary decelerator, including pedestal
And cover board, it is equipped with sealing ring between the base and cover plate, is correspondingly provided with annular groove, the sealing on the base and cover plate
Interior outside periphery and annular groove the medial surface fitting of circle, annular groove bottom surface are equipped with several bored holes, and bored hole and annular are recessed
Slot is orthogonal, and support plate is equipped in the bored hole, and 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 reasonable bored hole number keeps resilient support distance between tie rods reasonable, thus
The support force interval that sealing ring is subject to is reasonable.
The beneficial effects of the utility model are: the utility model is novel in design, and it is simple and reasonable, it is embedded in annular groove
Interior sealing ring tightness is high, the branch after sealing ring aging deformation, under the elastic force effect of elastic supporting bar, in base and cover plate
Fagging tightly clips sealing ring, so that sealing ring is continued the intersection for being tightly filled in base and cover plate, keeps good leakproofness,
It avoids result in pedestal for lubricating the oil leak of pivoting support and worm screw, avoids influencing normally making for rotary decelerator
With.
Detailed description of the invention
The utility model will illustrate by example and with reference to the appended drawing, in which:
Fig. 1 is the appearance diagram of the utility model；
Fig. 2 is the structural schematic diagram of the utility model；
Fig. 3 is the cutting plane schematic diagram of A-A in Fig. 1.
Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
As shown in Figure 1-3, the utility model is a kind of high leakproofness rotary decelerator, including pedestal 1 and cover board 2, institute
It states and is equipped with sealing ring 3 between pedestal 1 and cover board 2, be correspondingly provided with annular groove 4, the sealing ring 3 on the pedestal 1 and cover board 2
Interior outside periphery and the fitting of 4 medial surface of annular groove, 4 bottom surface of annular groove be equipped with several bored holes 5, bored hole 5 and annular
Groove 4 is orthogonal, and support plate 6 is equipped in the bored hole 5, is equipped with elastic supporting bar 7 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 bored 5 bottom surface of hole, support plate 6 respectively.
5 quantity of bored hole is 12-20.
The utility model is novel in design, simple and reasonable, and the sealing ring tightness being embedded in annular groove is high, sealing
After enclosing aging deformation, under the elastic force effect of elastic supporting bar, the support plate in base and cover plate tightly clips sealing ring, makes close
Seal continues the intersection for being tightly filled in base and cover plate, keeps good leakproofness, avoids result in pedestal for lubricating
The oil leak of pivoting support and worm screw avoids the normal use for influencing rotary decelerator.
Above-mentioned foundation the utility model is enlightenment, and through the above description, relevant staff completely can be not
In the range of deviateing this item utility model technical idea, various changes and amendments are carried out.This item utility model it is technical
Range is not limited to the contents of the specification, it is necessary to which the technical scope thereof is determined according to the scope of the claim.
