【Technical field】
The present invention relates to a kind of separable Retarder work cavity configuration of rotor.
【Background technology】
The method of current Retarder reduction idle capacity loss has following several:The 1st, flow-disturbing is installed inside working chamber
Device, reduce idling loss by upsetting in working chamber airflow circulating.The 2nd, moveable spoiler is installed in working chamber,
Spoiler is opened or closed by hydraulic control or automatically controlled mode, is substantially to reduce the relative area in rotor section to subtract
Small working chamber effectively plays the purpose for reducing idle capacity loss.The conventional two kinds technologies for reducing empty damage are needed in structure at present
Install hydraulic pressure or automatically controlled executing agency, complex structure additional.If disturbing flow device comes off will to cause to damage to retarder in working chamber
It is bad, increase trouble point.
【The content of the invention】
A kind of shortcoming it is an object of the invention to overcome above-mentioned prior art, there is provided separable hydrodynamic retarding of rotor

【Specific embodiment】
The present invention is described in further detail below in conjunction with the accompanying drawings：
Referring to Fig. 1-3, the separable Retarder work cavity configuration of rotor of the present invention, including it is housing 6, rotor 4, fixed
Son 2 and splined shaft 1；Rotor 4 is connected by helical teeth internal spline 41 with the helical teeth external splines 42 of splined shaft 1, and oblique spline form is such as
It is to be coordinated using gap between dextrorotation involute profile, interior external splines shown in Fig. 2 and Fig. 3, flexible relative motion need to be ensured.It is fixed
Son 2 is fixed on housing 6 by bolt 5, and rotor cut spring 3 is installed in the left side of rotor 4, and the right-hand member of rotor cut spring 3 is bullet
Spring abutment 7, by the shaft shoulder positioning at the oblique spline of splined shaft 4, right side is sequentially installed with bearing adjust pad 8, the to the left side of spring base 7
Two cone bearings 9, platen 10, cushion block 11, tense locked eventually through bolt 12.The inner ring of the first cone bearing 13 is with splined shaft 1
Interference fit, by shaft shoulder positioning, left side is provided with retarder drive gear 14 on inner ring right side, and retarder drive gear passes through spline
It is connected on axle 1, the moment of torsion of retarder can be passed to gearbox by gear 14, and the right-hand member of gear 14 passes through pad 15 and bolt 16
It is fixed.
Principle of the invention：
When the axial force to the right of rotor 4 is sufficiently large, rotor 4 will compression rotor cut spring 3 move right, near fixed
Son 2, when axial force is not enough to overcome the elastic force of rotor cut spring 3, rotor 4 is played and reduces idling loss away from stator
Purpose.Program simple structure, reliability is high.As shown in figure 1, looking at from left to right, rotor 4 is rotated counterclockwise with splined shaft 1.
Because rotor 4 is connected by helical spline with splined shaft 1 so splined shaft 1 can produce axial force to the right to rotor 4, when being more than
In Fig. 1 during the elastic force of rotor cut spring 3, rotor will be made to left movement；Producing another component simultaneously makes rotor 4 relative to spline
Axle 1 rotates.
The course of work of the invention：
When retarder works, the cavity between rotor 4 and stator 2 is oil-filled, and retarder produces resistance, the work on oblique spline
Firmly increase, helical teeth also increases therewith to the axial thrust load to the right of rotor 4, now compressible rotor cut spring 3 moves right
It is dynamic, rotor 4 is close to stator 2, be conducive to retarder to produce larger moment of torsion.After retarder is released to be braked, rotor 4 with it is fixed
The fluid in cavity between son 2 is drained, and the fluid in working chamber is changed into air, the resistance ratios that retarder agitation air is produced
The resistance stirred produced by oil can be much smaller, so the axial force for tiltedly being produced between spline 1 and rotor 4 corresponding can also reduce, this
When axial force be not enough to overcome elastic force, under spring force, rotor 4 will be moved to the left, pull open between stator 2 away from
From, play reduce idle capacity loss purpose.
Above content is only explanation technological thought of the invention, it is impossible to limit protection scope of the present invention with this, every to press
According to technological thought proposed by the present invention, any change done on the basis of technical scheme each falls within claims of the present invention
Protection domain within.
