When above-mentioned machine, component coenosarc of liquid two elements and link about axially the bridging element of conjuncted static pressure torque converter (transmission device) can be decomposed into axially by multi-plate friction clutch, at this moment oil circuit can join from exterior line, also can join by the bilayer sleeve from central shaft.As the planetary mechanical torque converter of a kind of static pressure, being characterized as of the planet seat of the pure machinery of the pure interior engagement of the coaxial type that its output terminal connects: one is circumferentially floated, coaxial and the coenosarc of interior external toothing, the axis of its axial axis and external gear 12 is a distance, and (gear ring 23 can be consolidated in housing can to form less poor engagement around the internal tooth of the external tooth of the interior external toothing 11 of the axis translation of external gear 12 and ring gear 23, also can make input, output element), the external tooth of the internal tooth of interior external toothing 11 and external gear 12 forms the engagement of few tooth difference, and two contact pointss are each other 180.Longitudinal axis on and have an identical offset, the increasing of the axis coaxle of the output shaft 6 of external gear 12 axis and fixed shaft type, speed reducer.The pure mechanical planet device that above-mentioned machine, component coenosarc of liquid planetary static pressure torque converter output shaft axially connect is not provided with 7 in figure two, 8 dynamic months block teeth and corresponding both sides sealing plate, as pure mechanical transmission, can be by hollow eccentric wheel as input element, external gear 12 and axle 6 are as output element, ring gear 23 is consolidated in the speed reducer of housing, can also output shaft 6 be input shaft, be the pure interior engagement speeder of output shaft with hollow eccentric wheel or ring gear 23.The deceleration characteristics that few tooth poor (planocentric) engagement of this Internal and external cycle is paid are that the external gear rotating speed is that sum is paid in inside and outside engagement, so its speed ratio can enter 3～7 low speed than the speed ratio forbidden zone of lacking tooth difference device.Since it have low noise, low line of contact speed, low profile of tooth contact stress, high profile of tooth bearing capacity and Contact Stress of Gear have only the external tooth engagement 1/10, the contact points linear velocity have only outer gearing 1/5～1/10, the contact points wasted work only is about 1%, noise than the low 10dB of external tooth engagement about and be to pay as the principal stress engagement of tooth with flexural strength singlely, so transmission power of the present invention in sum can reach tens thousand of kilowatts without restriction, so more be applicable to the main transmission of large ship.And when axle 6 and external gear 12 be input element, be that the high power speed-increasing device of the low speed ratio of output element more is applicable to main transmissions such as combustion gas and steam turbine with hollow eccentric wheel, the hollow eccentric inside and outside circle bearing of this speeder is a hydrodynamic bearing.
The planet seat of the oil hydraulic pump of machine, component coenosarc of liquid and oil hydraulic motor is NGW, NW, (NGW-is that the device of a ring gear, an external gear and one group of common gear is planocentrictype to NGWN; NW-is the device with an external tooth, and NGWN-is the NGW type device with two ring gears) to constitute with the sun gear during type structure be driving link, circumferentially the planet carrier that floats is the deceleration stepless speed changes devices of output member; With planet carrier be driving link, the speedup stepless speed changes devices when sun wheel shaft is output member.When the planet seat was the few tooth difference type of N, NN type, constituting with the eccentric wheel was the subtracting of driving link, speed change gear.With pin framework, or ring gear is driving link, increasing when eccentric shaft is output member, speed change gear.The profile of tooth of said apparatus can be involute profile, cycloidal tooth profile, arc toothed.The static pressure torque converter of machine, component coenosarc of liquid can be used as separate part in order to drive other forms of load device.The planet device that meshes in pure can be used as separate part and cooperates in order to drive other forms of load device with other power units.Can also output shaft 6 be input shaft, be the speeder that output shaft forms pure interior engagement with hollow eccentric wheel or ring gear 23.
When the speed ratio that can obtain the various gears of clockwise and anticlockwise with multi-plate friction clutch and many rows of planetary base device when conjuncted, and infinite variable speed scope increases to machinery between (subtracting) speed ratio zero.
The axial two ends of the inner ring planet seat of interior external toothing 1, fixed two blocks of side plates form the oil closed cavity of internal tooth planet seat on planet carrier or output mechanism, are that the internal tooth by sun gear 5, planet wheel 4, planet carrier 9, interior external toothing 1 constitutes when it is NGW, NW, NGWN type; When lacking tooth difference type, formed by internal tooth, planet wheel 4, the dynamic month block teeth 7 of interior external toothing 1 by N, NN.(the NGW type sees in Chemical Industry Press's mechanical design handbook the 618th page of volume second edition for details)
Principle of the present invention is: with radially conjuncted be example, circumferentially the interior external toothing 1 that the floats reaction force of loading with lotus outside is being with ring gear 3 to be passive rotation status under driving, its rotating force and speed thereof are subjected to the pressure of moon block teeth 2 hyperbaric chambers and the restriction of flow, so it has the automatic adaptability that gathers way and descend automatically with load, at high-pressure outlet end adjustable Flow valve is set and regulates flow (can place the housing outer wall), so it has the adjustability of the stepless variation of speed, reach infinite variable speed purpose whereby, the back pressure moment of hyperbaric chamber then balances each other with loading with lotus moment outward, so it has the feature of permanent power.Have one and the joining active member of motor (sun gear, hollow eccentric wheel or planet carrier) in the inner ring planet seat, can rely on the double layer oil pipe 6 at output shaft 6 centers to make the high low pressure oil circuit, the high pressure oil that is produced by the outer ring internal gear pump passes through the oil circuit of (outward) in the casing, and corresponding hydraulic control component, to the hyperbaric chamber fuel feeding of inner ring planet motor; Also can make driving part (pump) to outer ring internal gear part (motor) fuel feeding by the inner ring planetary gear train.
Advantage of the present invention is: mechanically operated teeth parts and mekydro element coenosarc, can realize the differential stepless change that superposes of machine, the second-rate power of liquid, and the tooth of engaging force and hydraulic pressure load is not together in a flash on a tooth, so bearing capacity is very high, volume can be very little, and pressure is at 300kg/cm when being used for high gear
2More than, total transmission effect rate can reach more than 90%, and the kinetic pressure of common hydrodynamic unit is 8kg/cm
2About, volume is big and efficient is low.The present invention is easy to emptying to realize the more high efficiency operation of pure machinery after crossing startup and impact load.
The present invention can be used for aspects such as automobile, train, boats and ships, engineering machinery.
The planet row (planet seat) of engagement in the present invention is pure have low line of contact speed (for outer gearing pay 1/5～1/10), low noise (the low 10dB of same machining accuracy), (outer gearing is paid and is generally 80～110kg/mm to hang down Contact Stress of Gear
2, the present invention is 5～10kg/mm
2) and low engagement wasted work (its value is linear with line of contact speed), and planet row of the present invention has the advantages that overall ratio is an Internal and external cycle speed ratio sum, its ratio coverage can be between 2.5～120, and applicable to vehicle traction, when it is used for speed increaser separately, can make the linear velocity of existing high gear transmission reduce by 3～5 times, thereby reduce engagement wasted work and cost greatly.Because the transmission efficiency height is so be applicable to high-power (more than the 10000KW) transmission.
