Abstract
The utility model relates to a non-slip static hydraulic mechanical coupler, which is more convenient to regulate the external characteristic thereof and nicely meet the characteristics of a coupler, a prime mover, and load matching performance according to the needs of users. The utility model is characterized in that the bucket wheel of the existing coupler is sheathed with a choking ring [C]; the choking ring [C] is a cylindrical surface; the width [B] can be altered as required; the cylindrical surface is provided with axially fixing slots whose number is identical to the number of the bucket vanes of the bucket wheel. By means of the different positioning of the choking ring [C] in circumferential direction, the axially fixing slots have different covering degree to the exit areas of the bucket vanes.
Description
The utility model relates to a kind of mechanical dydraudynamic drive unit.
Existing no slippage hydrostatic machinery coupler does not have the adjustable collar joint, causes the performance of designed machine and expection characteristic that very big difference is arranged, and can't adjust.This reason mainly is that the bucket wheel in the coupler is once made after the shaping, and the overcurrent size can't change, and the characteristic that makes coupler can't be adjusted compensation when having than big-difference with former design.
The purpose of this utility model is to propose a kind of characteristic and former design when occurring than big-difference when coupler, by adjusting the bucket wheel block ring in the coupler, can change the mechanical coupler of a kind of no slippage hydrostatic of the characteristic of coupler.
Main points of the present utility model are the bucket wheel structures that change coupler, i.e. block ring C of suit on existing coupler bucket wheel, and block ring C is the cylndrical surface, the change as required of its width B, and on the cylndrical surface, have the axial dead slot identical with the number of sheets that struggles against.By making the difference location of block ring C, make axial dead slot different covering degrees be arranged to bucket leaf discharge area at circumferencial direction.The width of dead slot is (1/2～1/3) b, and axial length is (0.7～0.8) bucket leaf length.
Describe the utility model theory structure in detail below in conjunction with Fig. 1, Fig. 2.Bucket wheel 3 supporting of balanced configuration is installed on two end faces of cylindrical shell 1 of sealing, and this takes turns 4 and links with planet, and housing 1 is formed power rotors with input shaft 6, and output shaft 2 is driven by central gear 5, and they form driven rotor.The bucket shape blade that some quantity are evenly arranged is housed on the bucket wheel, fills the working liquid body of some in the housing.When power rotor is rotated by prime mover driven,, make driven rotor be subjected to driving the work mechanism rotation with the onesize moment loading of input side by means of the synergy of liquid, bucket wheel and planetary gears, realize the function of power transmission, in declared working condition, the input output rotating speed equates, n
1=n
2, do not have slippage to exist.
This transmission device has two Key Performance Indicators, the firstth, i=(n
2)/(n
1The maximum transmitted moment M of)=1.0 o'clock
1.0, the secondth, torque ratio K=(M
0)/(M
1.0), M
0Transmission torque value when being i=0.M
1.0And M
0Value must with the motor power characteristic coupling of institute adapted, improve mechanical system starting characteristic and overload protective function otherwise can not play effectively.
The utlity model has can be according to the more convenient adjustment external characteristics of user's needs, satisfies better and the characteristics of the matching performance of prime mover and load.M is only pressed in bucket shape design in the utility model
1.0Value determines that the block ring structure only influences M
0Value.
Fig. 1 is the utility model principle assumption diagram
Fig. 2 is for being added with the bucket wheel structural drawing of block ring in the utility model
Embodiment: when the utility model carries out work on 40 kilowatts transmission device, can make K=10 be adjusted to K=2～2.5, and M
1.0Value remains unchanged.The utility model is used in the auxiliary system of the 600000 kilowatts of unit boilers in the 3rd power station, Harbin, this system requirements K=3.5.
Claims (3)
1, a kind of no slippage hydrostatic machinery coupler comprises rotary shell [1], output shaft [2], and bucket wheel [3], planetary pinion [4], central gear [5] is formed, and it is characterized in that being added with on the bucket wheel [3] block ring [C].
2, coupler according to claim 1 is characterized in that block ring ［ C ］ is the cylndrical surface.
3, coupler according to claim 2 is characterized in that having on the block ring ［ C ］ of cylndrical surface identical with the number of sheets that the struggles against groove of axially deciding.
