Mismachining tolerance produced by during and build-up tolerance accumulation during assembling.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the invention discloses a kind of for hydrodynamic retarding in parallel
Device elastic device, is installed on that retarder housing is embedded to be placed on outside splined shaft, and elastic device is annular workpieces, and annular workpieces includes
The trapezoidal ring body in top and bottom inverted trapezoidal ring body, the trapezoidal ring body in top is identical with inverted trapezoidal ring body center drilling aperture, bottom,
The trapezoidal ring body in top and bottom inverted trapezoidal ring body are connected with each other.
Wherein, the trapezoidal ring body in top and bottom inverted trapezoidal ring body planar shaped acutangulate a and are 7.5-15 °, bottom inverted trapezoidal ring
Body and top trapezoidal ring body planar shaped acutangulate b and are 75-82.5 °, acute angle a and acute angle b complementary angle each other.
Wherein, annular workpieces is circlip for shaft, the one in E shape circlip or C-shaped circlip, annular workpieces
Use the disposable punch forming of spring steel material.
Preferably, annular workpieces is E shape circlip, and E shape circlip includes jump ring circle body and regulation buckle structure,
Jump ring circle body is arc E type structure, and the internal diameter of jump ring circle body is the external diameter 1/3-1/2 of jump ring circle body, and regulation buckle structure is embedded
It is installed on end, jump ring circle body two ends.
Wherein, regulation buckle structure includes regulation draw-in groove and regulation buckle, and regulation draw-in groove is opened in jump ring circle body two ends
End, regulation buckle installation settings is in regulation draw-in groove, and regulation draw-in groove and regulation buckle are provided with slip latch.
The method have the advantages that
The present invention is designed by design of part optimization, in Retarder, output shaft, taper roll bearing, slow
The tolerance stack formed after multiple parts assemblings such as device lid, stator, bearing race, uses elasticity to be automatically adjusted the ring-type of design
Workpiece carries out tolerance elimination, and instead of conventional spacers cone governor bearing and dissociate gap, overcomes the trip of pad cone governor bearing
When sowing discord gap, assembly difficulty is big, cause cone bearing to dissociate problem that gap length differs, and improve cone bearing is the life-span, the most also
Improve retarder is the life-span, travels for vehicle and bull point insurance.

Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, right
The present invention is further elaborated.
Embodiment 1
As Figure 1-4, the invention discloses a kind of for Retarder elastic device in parallel, be installed on retarder shell
Body 1 is embedded to be placed on outside splined shaft 2, and elastic device is circlip for shaft 3, and circlip for shaft 3 includes top keystone ring
Body 4 and bottom inverted trapezoidal ring body 5, the trapezoidal ring body in top 4 is identical with inverted trapezoidal ring body 5 center drilling aperture, bottom, and top is trapezoidal
Ring body 4 and bottom inverted trapezoidal ring body 5 are connected with each other.
Wherein, it is 9.5 ° that the trapezoidal ring body in top 4 and bottom inverted trapezoidal ring body 5 planar shaped acutangulate a, bottom inverted trapezoidal ring body
5 to acutangulate b be 80.5 ° with top trapezoidal ring body 4 planar shaped, acute angle a and acute angle b complementary angle each other.Circlip for shaft 3 uses bullet
The disposable punch forming of spring Steel material.
Operation principle:
In Retarder, multiple parts such as output shaft, taper roll bearing, retarder lid, stator, bearing race
A ring-type tolerance stack closed is formed, if not using ring-type trim designs, then this fluid power cannot be made to delay after assembling
Speed device reaches to design requirement, or can not make car deceleration, or the poor effect slowed down, in order to make retarder device reach design
Requirement, the circlip for shaft 3 that the application uses elasticity to be automatically adjusted design carries out tolerance elimination, and instead of conventional spacers
Cone governor bearing dissociates gap, overcome pad cone governor bearing dissociate gap time assembly difficulty big, between causing cone bearing free
The problem that gap is not of uniform size, improve cone bearing is the life-span, and also improve retarder is the life-span simultaneously, travels again many one for vehicle
Code insurance danger.
