Description
Technical field
The utility model relates to speed reducer steel wheel technical field of sealing technology, specifically design a kind of oil-leakage-prevention harmonic wave speed reducing machine steel
Wheel.
Background technique
The Market Feedback and investigation of recent five years, the either international higher speed reducer brand of popularity or domestic popularity
Higher brand, a kind of situation all occur is exactly: when client uses more than 2000 hours or more, leakage takes place in part speed reducer
Oily situation, maintenance cost increase suddenly, and production management cost allowance is very big.By furtheing investigate and analyzing, the H-type knot of steel wheel seal groove
Structure design (as shown in Figure 1) causes O-type sealing ring to be extruded breakage, and grease exosmoses and oil leak over time.Solution is done
Method can not only simply replace an O-type sealing ring reassemble, but to return producer ressemble with accuracy test and
Calibration, whole process is comparatively laborious, and not can guarantee the sealing element newly replaced and oil leak thing is not occurring in subsequent use process
Part.Market needs novel and stable speed reducer to give thorough solution.
Utility model content
The technical problems to be solved in the utility model is sealing ring in the existing speed reducer steel wheel quilt in assembling process
It squeezes excessive thus the problem of being subject to crushing, less oil leak risk.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model are as follows: a kind of novel anti-leakage oil harmonic wave subtracts
Fast machine steel wheel, including steel wheel ontology, are provided with seal groove on steel wheel ontology, and O-type sealing ring, institute are provided in seal groove
State the opposite two side walls of seal groove includes notch, middle part and trench bottom from top to bottom；The centre of two of them side wall
Portion is obliquely installed to the same side, and trench bottom forms chamfering, chamfering lateral bend to outside slot；O-type sealing ring is respectively by two side walls
Interlude and the active force for sealing trench bottom；The groove width of seal groove is less than the diameter of sealing ring.
Further, the notch of the seal groove is also formed to curved chamfering on the inside of slot.
Further, the bottom surface of the sealing ring middle part and seal groove is in 75 ° of angle.
Further, wherein the groove bottom of middle part and seal groove formed acute angle side wall be left side wall, middle part with it is close
The side wall that the groove bottom of sealing groove forms an angle is right side wall, and the notch chamfering diameter and trench bottom chamfering diameter of left side wall are distinguished
Greater than the notch chamfering diameter and trench bottom chamfering diameter of right side wall, and the notch chamfering arc length and trench bottom of left side wall are fallen
Angle arc length is respectively greater than the notch chamfering arc length and trench bottom chamfering arc length of right side wall.
From above-mentioned technical proposal it can be seen that the utility model has the advantage that the design of double chamfering J-type seal grooves has
Effect prevents speed reducer operation process by the flowing velocity of hot grease and overflows risk, and reliability is promoted to 100% or more；Newly
The double chamfering J-type seal grooves of type can effectively absorb O-ring and squeeze extending direction in assembling process, self adjust most in groove
Excellent stationary state；The timeliness of effectively save assembly crewman's operating process, further increases production capacity and production efficiency；Effectively solve
The stability of client's use process further increases the service life of speed reducer.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the speed reducer steel wheel of the prior art.
Fig. 2 is the structural schematic diagram of the utility model.
Specific embodiment
Specific embodiment of the present utility model is illustrated below in conjunction with attached drawing.
As shown in Fig. 2, the novel anti-leakage oil harmonic wave speed reducing machine steel wheel of the utility model includes steel wheel ontology 2, steel wheel diameter
250mm is provided with seal groove on steel wheel ontology 2, takes the design slot of double chamfering J-type seal grooves, deep 6mm, slot inner width 8mm,
Groove width refers to distance of the seal groove two side walls between the projection of groove bottom.O-type sealing ring 1, institute are provided in seal groove
State the opposite two side walls of seal groove includes notch 3, middle part 4 and trench bottom 5 from top to bottom；In two of them side wall
Between portion 4 be obliquely installed to the same side, trench bottom 5 formed chamfering, chamfering lateral bend to outside slot；O-type sealing ring is respectively by two
Side wall interlude and the active force for sealing trench bottom；The groove width of seal groove is less than the diameter of sealing ring.
It is matched with steel wheel during part is assembled, O-type sealing ring forces O- for by the pressure under upper
Type sealing ring extends to other 3 directions, and the design on the inclined-plane and the angle R of two-way J-type seal groove can more smoothly guide O-
The position of type sealing ring towards setting is mobile and allows its self-control to optimal seal position.Effectively O-type sealing ring is avoided to assemble
Process crushes and oil leak outwardly against caused overflow to be matched part.
The notch 3 of seal groove is also formed to chamfering curved on the inside of slot, and the bottom surface of middle part 4 and seal groove is in 75 °
Angle.It is left side wall, the groove bottom of middle part and seal groove that wherein the groove bottom of middle part 4 and seal groove, which forms the side wall of acute angle,
The side wall for forming an angle is right side wall, and the notch chamfering diameter and trench bottom chamfering diameter of left side wall are respectively greater than right side wall
Notch chamfering diameter and trench bottom chamfering diameter, and the notch chamfering arc length of left side wall and trench bottom chamfering arc length difference are big
In the notch chamfering arc length and trench bottom chamfering arc length of right side wall.Sealing ring can prolong when being squeezed power to trench bottom
Exhibition, the chamfering being bent outwardly can be big for the volume that the ratio for providing space, and extending to the left extends to the right that extends.
To sum up: increasing the linear distance of contact sealing surface of the sealing surface of O-type sealing ring with steel wheel, double chamfering J-type sealings
The design of slot effectively prevents speed reducer operation process by the flowing velocity of hot grease and overflows risk, and reliability promotion is arrived
100% or more；Novel double chamfering J-type seal grooves can effectively absorb O-ring and squeeze extending direction, groove in assembling process
It is interior self to adjust optimal stationary state；The timeliness of effectively save assembly crewman's operating process, further increases production capacity and production
Efficiency；The stability for effectively solving client's use process, further increases the service life of speed reducer.
The manufacture craft of the utility model is as follows.
1: corresponding steel wheel size being designed according to the specification size of harmonic wave speed reducing machine, the Cheng Qian's design of crossing for manufacturing steel wheel is suitble to
Double chamfering J-type seal groove sizes, select matched O-type sealing ring.
2: selecting suitable numerically controlled lathe and CNC to carry out steel wheel dimensioned and carry out roughing；
3: selecting suitable slotting cutter to carry out double chamfering J-type seal groove processing, the control of face seal rooved face roughness exists
1.6 and less, it is ensured that due to roughness it is bad caused by oil leak risk.
4: the full-scale constant temperature inspection of three-D, appearance test.
5: the oxidation of steel wheel entire surface and antirust treatment improve service life and corrosion resistance.
