Detailed description of the invention
Below in conjunction with accompanying drawing, a preferred embodiment of the present invention is elaborated.But protection scope of the present invention is not limited to following embodiment, the simple equivalence namely in every case done with the present patent application the scope of the claims and description changes and modifies, and all still belongs within patent covering scope of the present invention.
As Figure 1-3, a kind of mechanical press liquid formula power coupling apparatus, comprise flywheel 1, the central part of this flywheel connects power input shaft 2, sun gear 3 is fixed in the other end that described power input shaft stretches out described flywheel, this sun gear engages several spaced planetary gears 4 by teeth, and several these planetary gears are engaged in by teeth again in the inner toothed surface of ring gear 5; Several this planetary planet pin 41 is fixed on planet stent 42, and this planet stent is connected with power output shaft 6 and is connected with second time friction plate 7 that several parallel interval are arranged in the mode of external tooth engagement; The outer toothed portion of described ring gear engages first time friction plate 8 of several parallel interval setting; another correspondence several this first time friction plate successively interval arranges several the first upper friction plates 9, and corresponding several this second time friction plate arranges several the second upper friction plates 10 in interval successively, several first upper friction plates and several first time friction plate are successively to inserting, several second upper friction plates and several second time friction plate are successively to inserting, several first upper friction plates and several second upper friction plates are meshed with the internal tooth of fuselage 20 respectively and are connected, push rod group 11 activity is set in fuselage 20, one end of this push rod group contacts with the annular projection portion 121 of cylinder piston 12, the other end accepts the thrust of spring 13, and this push rod group can make several first upper friction plates and several first time mutual frictional engagement of friction plate to spring one lateral movement and make several second upper friction plates and several second time friction plate be separated from each other under this piston ring-type lug boss promotes simultaneously, and this push rod group can make several second upper friction plates and several second time mutual frictional engagement of friction plate to cylinder piston one lateral movement and make several first upper friction plates and several first time friction plate be separated from each other under spring force effect simultaneously.
Wherein, preferably, described planetary gear is three, is uniformly distributed between described sun gear and ring gear; Described flywheel is by spline joint power input shaft; The first from left end disc part 14 of described push rod group contacts with the annular projection portion 121 of piston 12, and right one end disc 15 of described push rod group is all the time by the thrust of spring.
This mechanical press adopts the ring gear arranging sun gear, the planetary gear engaged with this sun gear in the power input shaft end that flywheel connects and engage with this planetary gear again with liquid formula power coupling apparatus, be connected to the planetary wheel mechanism that power output shaft forms this device by planet pin and planet stent simultaneously.Wherein, the first upper friction plate, first time friction plate form multiple-piece clutch coupling apparatus, and the second upper friction plate, second time friction plate form multiple-piece brake coupling apparatus.Cylinder piston, annular projection portion, push rod group, the first from left end disc part, right one end disc and spring composition lotus root close switching mechanism.Cylinder piston moves to right and promotes the combination of multiple-piece clutch coupling apparatus, and the multiple-piece of push rod group promotion simultaneously power cutoff mechanism moves to right and overcomes spring thrust, and brake coupling apparatus is removed.Its concrete motion process is as follows:
During the non-air feed of cylinder, by spring force, push rod group is moved to the left, the second upper friction plate and second time friction plate frictional engagement, the first upper friction plate and first time friction plate are separated, namely spring force makes brake coupling apparatus be in bonding state, and clutch coupling apparatus is in disarm state.Due to second time, friction plate is arranged on planet stent output shaft, second upper friction plate is arranged on fuselage, and be clamped by spring force, the combination of the coupling apparatus that therefore brakes makes planet stent be fixed, and the releasing of the coupling apparatus of clutch simultaneously makes ring gear be in freely-movable state.Therefore, the rotary motion that flywheel is imported into by power input shaft, drives planetary gear rotation by sun gear, drives ring gear to rotate, and then drives first time friction plate of clutch coupling apparatus to rotate.
During cylinder air feed, promote piston and move to right, overcome the effect of spring force and the first upper friction plate and first time friction plate are combined, the second upper friction plate is separated with second time friction plate, and namely clutch coupling apparatus combines, and brake coupling apparatus is removed.The releasing of brake coupling apparatus makes planet stent move, the combination of clutch coupling apparatus makes the rotary motion of ring gear be braked, and under the driving of sun gear, planetary gear is along in ring gear revolution situation, also drive planet stent to rotate, and make power output shaft be able to Power output.
This mechanical press liquid formula power coupling apparatus introduces the differential principle of planetary wheel mechanism, makes the rotation alternating movement of train ring gear and planetary gear carrier, thus realizes transmission and the cut-out of power.Owing to being undertaken by planet circular system inputting, the conversion of outlet chamber, therefore have the speed reducing ratio of (1+i), and output torque has (1+1/i) increase effect doubly, this mechanism has the function of TRANSMISSION.Input link flywheel is arranged at device end side, by power shaft transmission.With clutch coupling unit rotating speed for benchmark, can have the speed increasing ratio of i=2.5 ~ 3, therefore flywheel is called as the accumulator of forcing press, its kinetic energy E=1/2JW
2, be a timing at institute's energy requirement, its rotating speed of corresponding raising W, reduces inertia (J=mR
2), and the weight of flywheel, size can be reduced, thus accomplish to save cost and the energy.In addition, this device is from entirety formation, and its housing, driving switching mechanism, friction plate etc. are all in fixing or non-rotating state, and the rotational energy loss therefore produced during motion has dropped to the limit.
