Description
Technical field
The present invention relates to rotary decelerator fields, more particularly, to a kind of anti-leak rotary decelerator.
Background technology
It is generally equipped with manhole on storage tank, comes in and goes out when the manhole on existing oil tank is overhauled for people or when cleaning, if but
Staff overhauls rotary decelerator, using pivoting support（It is commonly called as turntable）As retarder driven part, it can be achieved that without limitation
Circumgyration and deceleration, larger axial force, radial load and power of toppling can be born, this kind of device can be fabricated to Standard Machine
Tool component to applied to it is various have rotation require mechanical equipments on, especially such retarder have precision it is high, it is compact-sized,
The advantages of large carrying capacity, is suitble to use under more severe work condition environment.Equipped with revolution branch in rotary decelerator pedestal
It holds, worm screw, then by cover closure, in the prior art, is generally sealed, prevented by the sealing ring being arranged between base and cover plate
Only oil leak, but this simple sealing structure in practical applications due to sealing ring aging deformation or oil temperature raising make it is close
Seal softens, and sealing ring is caused to skid off, and leakproofness reduces, and still has the thing of oil leak.
Invention content
The present invention is above-mentioned in order to overcome the shortcomings of, provides a kind of anti-leak rotary decelerator, including base and cover plate,
It is equipped with sealing ring between base and cover plate, the ring that cross section is inverted trapezoidal is respectively equipped on the face that the base and cover plate is combined
Connected in star has been uniformly arranged several straight-bars on the annular groove bottom surface, and the cross section of the sealing ring is by rectangle and two
The polymorphic structure of trapezoidal composition, two trapezoidal arranged symmetrically in rectangle both sides, and trapezoidal long bottom edge is connected with rectangle, the sealing
Several bored holes it have been uniformly arranged on the two sides of circle respectively, base and cover plate passes through several fasteners for being arranged on the outside of sealing ring
Connection.
Preferably, the straight-bar and bored hole number are equal.
Preferably, the depth of the annular groove<Trapezoidal height in sealing ring cross section.
The present invention is beneficial aspects：In use, the both sides of sealing ring（That is trapezoidal portions）On embedded base and cover plate
In annular groove, the side of sealing ring and annular groove madial wall are bonded, and the straight-bar in annular groove is inserted into bored on sealing ring
In hole, the degree that is connected firmly of sealing ring and annular groove is enhanced, when sealing ring aging deformation or the excessively high deformation of temperature, one
Aspect, straight-bar and bored hole limit sealing ring and skid off, on the other hand, the part being reserved on sealing ring outside annular groove
Along in annular groove inner wall filling annular groove, continues to be full of annular groove, keep original sealing effect, effectively prevent moistening
Lubrication leakage.
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 schematic diagram of pedestal of the present invention；
Fig. 3 is the cutting plane schematic diagram of A-A in Fig. 1；
Fig. 4 is the schematic diagram of sealing ring of the present invention.
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 1-4, the present invention is a kind of anti-leak rotary decelerator, including pedestal 1 and cover board 2, pedestal 1 and lid
It is equipped with sealing ring 3 between plate 2, it is recessed that the annular that cross section is inverted trapezoidal is respectively equipped on the face that the pedestal 1 and cover board 2 are combined
Slot 4 has been uniformly arranged several straight-bars 5 on 4 bottom surface of the annular groove, and the cross section of the sealing ring 3 is by rectangle 31 and two
The polymorphic structure of a trapezoidal 32 composition, two trapezoidal 32 are symmetrical arranged in 31 both sides of rectangle, trapezoidal 32 long bottom edge and rectangle 31
It connects, has been uniformly arranged several bored holes 6, pedestal 1 and cover board 2 on the two sides of the sealing ring 3 respectively and has been sealed by setting
Several fasteners 7 in 3 outside of circle connect.
The straight-bar 5 is equal with 6 quantity of bored hole.
The depth of the annular groove 4<Trapezoidal 32 height in 3 cross section of sealing ring.
In use, the both sides of sealing ring（That is trapezoidal portions）In annular groove on embedded base and cover plate, sealing ring
Side and the fitting of annular groove madial wall, the straight-bar in annular groove are inserted into the bored hole on sealing ring, enhance sealing ring and
The degree that is connected firmly of annular groove, when sealing ring aging deformation or the excessively high deformation of temperature, on the one hand, straight-bar and the limitation of bored hole
Sealing ring skids off, and on the other hand, the part being reserved in outside annular groove on sealing ring is filled out along annular groove inner wall
Enter in annular groove, continues to be full of annular groove, keep original sealing effect, effectively prevent oil leak.
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.
