Abstract
The utility model discloses a shield wheel of hydraulic torque converters and an improvement on the end face seal of the shield wheel and the pump wheel. The shield wheel is composed by welding an end cover and a shield cover, wherein the combination face of the shield wheel and the pump wheel is provided with a ring of tiny convex ribs. The aforementioned structure uses the convex ribs to replace an O-shaped seal ring for seal. Tests prove that under the water pressure of 1MPa, the structure can keep pressure for 10min without leakage, and the shield wheel is welded from steel elements to reduce weight by 7kg. The improvement reaches all technical requirements of the prior art and can reduce production cost.
Description
Affiliated technical field
The utility model relates to fluid torque converter, the especially a kind of cover wheel of fluid torque converter and the improvement of cover wheel and pump impeller end face seal.
Background technique
In the prior art, fluid torque converter is generally linked to each other with motor by the cover wheel by the revolving part pump impeller, between pump impeller and cover wheel, carry out static seal with the O RunddichtringO, assembling is when putting the O RunddichtringO, use butter that the O RunddichtringO is bonded in the cover wheel seal groove, be placed on then on the pump impeller, use Bolt Connection.When carrying out cleanliness testing, find that the impurity that is caused by butter weighs 100 milligrams, do not meet product requirement, make hydraulic transmission oil aging in advance easily.In addition, the cover wheel adopts the cast inblock of HT300 cast iron, Heavy Weight, reject rate height.
The model utility content
The technical problems to be solved in the utility model is that fluid torque converter cover wheel and cover wheel are improved with the pump impeller end face seal, makes the cover wheel in light weight, and the cover wheel is reliable with the pump impeller sealing.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of cover wheel of fluid torque converter and the improvement of cover wheel and pump impeller end face seal, it is made of cover wheel, pump impeller, it is characterized in that: the cover wheel is welded by end cap and cover cap two-part of steel, is provided with the small convex tendon of a circle on the junction plane of cover wheel and pump impeller.
The beneficial effects of the utility model are: after adopting said structure, the utility model is between cover wheel and pump impeller junction plane, and employing small convex tendon of a circle on cover wheel junction plane substitutes the sealing of O RunddichtringO, through testing, under the 1MPa water pressure, pressurize 10 minutes and ne-leakage; Cover wheel reaches 7 kilograms by the steel part weight reduction that is welded.Above-mentioned improvement reaches former every technical requirements fully, simultaneously, has reduced cost of production.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the utility model embodiment sectional structure schematic representation;
Fig. 2 is convex tendon cross section, an A place enlarged view among Fig. 1.
1. end caps among the figure, 2. cover cap, 3. nut, 4. spring washer, 5. plain washer, 6. bolt, 7. pump impeller, 8. convex tendon.
Embodiment
As shown in Figure 1, because price of steel product is continuous high and more and more higher to the requirement of turbidity test with the client, the utility model improves the cover wheel of fluid torque converter and the sealing of cover wheel and pump impeller 7 end faces, the cover wheel is welded by end cap 1 and cover cap 2 two-part that the steel plate stretching forms, original cover wheel adopts the cast inblock of HT300 cast iron, 16 kilograms of net weight, reject rate height, now change steel part welding net weight into and have only 9 kilograms, every technical order reaches former technical requirements.For covering the sealing problem of wheel with pump impeller 7 end faces is to be provided with the small convex tendon 8 of a circle on the junction plane of cover wheel and pump impeller 7.Like this, connect with bolt 6, nut 3, spring washer 4, plain washer 5 with the flange of pump impeller 7 at the cover wheel, convex tendon 8 on the cover wheel closely contacts with pump impeller 7 junction planes and imbeds because of stressed, substitute the sealing of O RunddichtringO, through test, under the 1MPa water pressure, pressurize 10 minutes and ne-leakage reaches every technical requirement fully.
As shown in Figure 2, the cross section of the convex tendon 8 that the circle on the junction plane of cover wheel and pump impeller 7 is small is an isosceles trapezoid, and its base angle is 45 °, and height is 0.08mm, and last base is 0.1mm.
Claims (2)
1. the improvement of the cover of fluid torque converter wheel and cover wheel and pump impeller end face seal, it is characterized in that: the cover wheel is welded by end cap and cover cap two-part of steel, is provided with the small convex tendon of a circle on the junction plane of cover wheel and pump impeller.
2. the improvement of the cover of fluid torque converter according to claim 1 wheel and cover wheel and pump impeller end face seal is characterized in that: the cross section of the convex tendon on the described cover wheel is an isosceles trapezoid, and its base angle is 45 °, and height is 0.08mm, and last base is 0.1mm.
