The working principle of present embodiment is: when motor start-up, motor shaft drives input shaft 7 rotations by the input shaft coupling, input shaft 7 is fixedly connected with active chamber left cap 19, thereby drive active chamber 8 with the speed rotation, peripheral pump 2 enters working state, and working oil is inhaled into pump chamber from the filler opening of peripheral pump 2 bottoms, be pumped to peripheral pump fuel tank 3, advance and oil-in chamber 32 by oil pipe 31 and oil inlet hole 27, enter active chamber 8 from the swivel assembly internal channel, working oil forms oil ring at the perisporium of active chamber 8; Curve wheels 13 are with active chamber 8 revolution, and right lateral star gear 15 is along the track high speed rotation of the tooth center line of ring gear 16 simultaneously; Because the working machine load is to forming and the opposite resisting moment of work sense of rotation with fast device output shaft 18, therefore when electric motor starting was initial, the ring gear 16 that connects firmly indirectly with output shaft 18 remained static.Curve wheels 13 are oil-filled fast in active chamber 8 oil rings, form powerful centrifugal moment, stop curve wheels 13 to continue rotation.Along with motor speed raises gradually, oil ring progressive additive in the active chamber 8, curve wheels 13 liquid filled ratios constantly increase, this centrifugal moment increases gradually, when centrifugal moment sum that centrifugal moment that 13 rotations of curve wheels produce and the revolution of curve wheels produce and operating load resisting moment reach balance, the right lateral star gear 15 on the output terminal of curve wheels 13 and the no longer relative movement of ring gear 16 of output terminal, the speed of output terminal obtains identical value with the speed of input end, start-up course finishes, and enters normal operating phase.
In start-up course, the break friction block 26 and 17 of the break friction wheels of control have contact force in various degree automatically, control right lateral gear rack 23 rotational resistances, reach the rotational speed of step-less adjustment planetary wheel carrier.When right lateral gear rack 23 is braked fully, be equivalent to a plane table thermoconductivity meter with the function of fast device; When right lateral gear rack 23 retarding brakings, be that stepless reduction of speed increases the soft start of square with fast device with the function of fast device.
Because peripheral pump 2 delivery rates are slower, when normal operation, keep the stable of active chamber oil mass, the start up period as the auxiliary feed-oil pump.External oil pump is by the low power frequency conversion motor driving, according to the requirement of the soft start of different size to starting time with fast device and client, when dispatching from the factory, external oil pump feed speed is finished program setting in electric control box, user also conversion in use sets.
Increase the square soft start and direct relation is arranged with the transmitting torque of fast device and the work oil mass in the active chamber, in certain working oil weight range, work oil mass in transmitting torque and the active chamber is proportional, but, when the oil mass of active chamber surpasses certain value, begin to reduce with the moment of torsion of fast device, therefore, oil mass limit channels 28 is set at active chamber, this is an another structural feature of the present utility model.
When operating load increased in short-term, therefore the output shaft speed meeting reduced suddenly, the state when increasing the square soft start with similar startup of fast device appearance this moment.When speed sliding difference greater than 0.2 the time, the velocity transducer of output terminal in time feeds back to control system with the information that output speed reduces suddenly, external oil feed pump work, break begins braking by feedback information simultaneously, enters start-up mode.When centrifugal moment sum that centrifugal moment that produces when 13 rotations of curve wheels and the revolution of curve wheels produce and operating load resisting moment reach new balance, right lateral star gear 15 and no longer relative movement of ring gear 16 on the curve wheels 13, the speed of output terminal obtains identical value once more with the speed of input end, enter normal operating phase, external oil feed pump is received with behind the fast feedback information, quit work, at this moment, break friction block 26 separates with break friction wheel 17.
When operating load increases to when dispatching from the factory the permission Maximum Torque that limits above floppy drive is moving with fast device, the output shaft rotating speed descends rapidly, and the stall phenomenon may appear, the velocity transducer of output terminal in time feeds back to control system with the information that output speed reduces suddenly, alarm pipes and notifies the staff, and control system is cut off motor power simultaneously.Thereby the safety of protection motor and working machine.
Since increase the square floppy drive moving with the above characteristic of fast driver and when normally moving the motor output speed identical with the working machine input speed, transmission efficiency is up to more than 0.992, normal operation does not have the phenomenon of transmission part heating, consider that startup and overload process can produce speed sliding difference, certain heat dispensing is arranged, so be provided with water cooler 30.
In the present embodiment, in order to guarantee the sealing needs of fuel tank, all bearings all are fixed with seal ring with the joint of axle.
The present embodiment purposes is very extensive, can be used for the rubber conveyor of multiple occasion, the use of various site surrounding etc., also can be used for the scraper plate machine of big specification, various pump and blower fan etc.As: recycle pump, crude oil pump, partial load pump, transfer pump, slurry pump, ash pump, reciprocating pump etc. and ventilator, mining air bells exhauster etc.
