Fig. 1, be the utility model plan structure schematic sectional view.
Embodiment
As shown in Figure 1, the utility model clutch of comprising the input shaft 1 that is connected with power engine, the output shaft 10 that is connected with working machine, casing (not shown), variable speed fluid coupling main body and combining with the variable speed fluid coupling main body.
Input shaft 1 and output shaft 10 are bearing in the airtight casing (not shown) by bearing, and lower box is the oil sump that fluid is housed, so as to supplying with transmission oil, control oil and lubricant oil to illustrated mechanism.
The variable speed fluid coupling main body comprises the shell 4 that is connected and constitutes the conduit holding cavity by the pump impeller B of input shaft 1 driven rotary, catheter block 2, conduit 3, with pump impeller B, constitutes the turbine T of active chamber and the shell on the back 5 that is connected with pump impeller B with pump impeller B.
Pump impeller B and turbine T have some radial blades respectively.
Catheter block 2 is arranged on the casing (not shown) and is positioned at input shaft 1 end, which is provided with the oil through that is communicated with oil feed pump and pump impeller B.
Conduit 3 and catheter block 2 combinations are so that the direct impouring casing of conduit 3 oil returns oil sump.
Clutch comprises clutch outer member 6, clutch inner casing 7, rotating hydraulic cylinder 8, ring-type plunger 9, solenoid valve 11, several pieces active friction plates 12 and several pieces are from movable friction plate 13.
Clutch outer member 6 has gear guide and oil through and is connected with shell on the back 5, rotates synchronously with input shaft 1.
Clutch inner casing 7 has gear guide and oil through and is connected and rotation synchronously with output shaft 10.
Rotating hydraulic cylinder 8 is connected with clutch outer member 6, and rotates synchronously with input shaft 1.
Ring-type plunger 9 is arranged in the rotating hydraulic cylinder 8, and moves along axis in rotating hydraulic cylinder 8.
Active friction plate 12 has external gear and is connected with clutch outer member 6.
Have internal gear and be connected from movable friction plate 13 with clutch inner casing 7.Several pieces active friction plates 12 and several pieces from movable friction plate 13 replace overlapping and clutches shell 6 and clutch inner casing 7 between.
Solenoid valve 11 is communicated with casing oil sump (not shown), clutch inner casing oil through or with rotating hydraulic cylinder respectively.
When the utility model starts, the control pump fuel feeding, operation solenoid valve 11, make solenoid valve 11 be communicated with oil sump and clutch inner casing 7 oil throughs, with fuel feeding in clutch inner casing 7, fluid enters between the driving and driven friction plate 12,13, rotation produces pressure and makes driving and driven friction plate 12,13 disengagements by fluid, this moment, oil feed pump was not to the active chamber fuel feeding that is made of pump impeller B and turbine T, turbine T, clutch inner casing 7 reach and also are halted state from movable friction plate 13, then power transmission is for throwing off operating mode, i.e. working machine stall, and power engine running as usual.
When normal operation and clutch still were disengaged condition after the utility model started, oil feed pump through the oil through of catheter block 2 to pump impeller B fuel feeding, power engine drives the pump impeller B with some radial blades through input shaft 1 and rotates, and driving fluid rotates thereupon, centrifugal force has increased the liquid energy (speed energy and pressure energy) of oily stream, and promptly pump impeller B is converted into the liquid energy with the mechanical energy of power engine input.Liquid stream flows to rush at the blade of turbine T and entad to do from the pump impeller B outlet that is positioned at the active chamber outer rim at a high speed, the mechanical energy (T and n) that the liquid that discharges can be converted into turbine T makes turbine T rotation with the output acting, and drives the rotation together thereupon of connected clutch inner casing 7.Partially liq flows in the conduit holding cavity that is made of shell 4 and pump impeller B in the rotation, and fluid pressure balances each other oil ring liquid level and the active chamber liquid level in the conduit holding cavity.Because active chamber fluid degree of filling and output speed have near proportional relation, thereby be the output speed of adjustable hydraulic coupler by the telescopic adjustment active chamber fluid degree of filling of electric actuator control conduit 3, be the speed governing operating mode this moment.Meanwhile drive connected clutch outer member 6 and active friction plate 12 rotations through the shell on the back 5 of pump impeller B, shell 4 rotary driving by input shaft 1.
When solenoid valve 11 commutations, make solenoid valve 11 be communicated with control pumps and rotating hydraulic cylinder 8 and when rotating hydraulic cylinder 8 fuel feeding, the pressure that fluid in the rotating hydraulic cylinder 8 produces with rotating hydraulic cylinder 8 rotations promotes ring-type plunger 9 and compresses driving and driven friction plate 12,13, make active friction plate 12 and combine from movable friction plate 13 and drive from movable friction plate 13 rotations, be that shell on the back 5 directly is connected with output shaft 10 through clutch, realize clutching operation, what make that power engine do not have " slippage " directly drags working machine.
During clutching operation, the rotation of rotating hydraulic cylinder inner fluid produces pressure the impacting force that friction plate forms is determined (derivation is omitted) by following formula:
In the formula: P-rotation fluid pressure;
A-ring-type sectional area of plunger;
R, the inside and outside radius of R-ring-type plunger;
N-input shaft rotating speed;
γ-fluid severe;
G-gravity accleration.
The utility model can be applicable in the speed governing operation of equipment such as blower fan, water pump, Belt Conveyors, each supporting control unit is implemented required action by following form, the variable speed fluid coupling main body that combines with clutch by clutch, realize disengagement, joint and three kinds of operating conditionss of speed governing, start to reach to take off to carry, and can be in operation and carry out speed governing or joint, to finish each operating mode needs, can satisfy the operation process and the variable speed energy saving requirement of equipment such as blower fan, water pump and Belt Conveyors.
As mentioned above, the utlity model has following advantage:
1, variable speed fluid coupling both domestic and external so far all has only the function of regulating output speed, the function of the existing adjusting output speed of the utility model, have again and throw off and engage (locking) function, the speed governing transmission can be had take off to carry to start, improve boundary for direct drive clutching operation reaches.
2, disengagement of the present utility model, joint and speed governing three operating conditionss are finished by mechanism, automatically controlled and hydraulic control coordination.When driving and driven friction plate is thrown off and when stopping to the active chamber fuel feeding that being made of pump impeller and turbine, then power transmission disengagement; Stretch by electric actuator control conduit, then the can regulate output speed; Solenoid valve commutates to the rotating hydraulic cylinder fuel feeding, and the fluid rotation produces pressure makes the ring-type plunger push driving and driven friction plate combination, and power transmission is engaged, and realizes not having the direct transmission in 1: 1 of " slippage ".
3, the utility model adopts novel, unique clutch, and promptly rotating hydraulic cylinder is subjected to oil and oil extraction from end face in rotation; Rotation by fluid in rotating hydraulic cylinder produces pressure, presses and need not outer fuel feeding, just can realize the clutch of driving and driven friction plate.
4, conduit of the present utility model and catheter block combination makes the direct impouring casing of conduit oil return oil sump, and the return line before having saved, and makes the utility model compact overall structure, size little.
