Introduce contents such as relevant design calculating of revolving the branch facility described in the utility model below:
During designing and calculating, the output torque that must guarantee to revolve the branch reducing motor is revolved the branch torque greater than maximum mensuration of screw connected tight fit device; Simultaneously, must guarantee to revolve component velocity and satisfy the technical indicator regulation.
1) revolves the selection of branch power mode
Screw connected tight fit device splits in the operation, and safety is primary.Therefore, when selecting to revolve branch power, must eradicate all potential safety hazards, guarantee being perfectly safe of split process.The power set that can satisfy the safety work of screw connected tight fit device have, the one, " air motor+decelerator " form revolve the branch device; The 2nd, " hydraulic motor+decelerator " form revolve the branch device; The 3rd, " fire-proof motor+decelerator " form revolve the branch device.
Air motor revolves the pluses and minuses of branch device: inflammable and explosive dangerous goods industries such as explosive, priming system extensively adopt compressed air as power source, the main gas transmission scheme that adopts in " screw connected tight fit device splits automatic production line ".If can realize the full Pneumatic Transmission of job platform, the branch that revolves that promptly utilizes " air motor+decelerator " to solve screw connected tight fit device connector is dismantled, can make full use of the power of air compressor, avoid the variation of type of belt drive, accomplish global optimization.But the present domestic air motor decelerator that does not have invariablenes turning speed, torque to adhere to specification, and only have U.S. Ingersoll-rand company that the air motor decelerator that adheres to specification is arranged abroad, but delivery cycle is grown, is cost an arm and a leg and do not have aftermarket attachment.In addition, revolve separating tests according to screw connected tight fit device connector screw thread, the moment of torsion of different manufacturers, the screw connected tight fit device of different batches connector is different, even same producer, same batch screw connected tight fit device to revolve that branch reverses also be different, the air motor decelerator is difficult to satisfy moment of torsion constantly to be changed and this operating mode of invariablenes turning speed, is difficult to accurately control and revolves the branch quality.Therefore, we have abandoned the air motor transmission scheme.
Pressure motor revolves the pluses and minuses of branch device: hydraulic drive is compared than Pneumatic Transmission, has characteristics such as pressure height, power output is big, volume is little, rotating speed is relatively stable.But need to increase a cover Hydraulic Power Transmission System, make that " screw connected tight fit device splits automatic production line " is complicated.Moreover the pressure of hydraulic motor transmission system, the size of torque are decided by load, and when load was excessive, the rotating speed of hydraulic motor can reduce; When load was too small, " creeping " phenomenon can appear.Above-mentioned undesirable element revolves the branch quality can for accurately control and cause certain difficulty, therefore, should not select the hydraulic drive scheme.
Fire-proof motor revolves branch device pluses and minuses: " fire-proof motor+decelerator " has invariablenes turning speed, detent torque greater than more than a times of nominal torque, in the nominal torque scope, the influence that motor speed is not changed by extraneous load (moment of torsion), be suitable for very much the screw thread dismounting, realize the integrated control of electrical-mechanical easily.Screw thread revolves the branch precision and can be controlled in the 0.19mm scope, can guarantee automatic control system, revolve the branch device according to setting technological process exactly, work reliably.Though increased by a cover reducing motor, can guarantee that screw connected tight fit device revolves the branch quality, reduces percent defective widely.And frock is changed convenient and swift, need not manually to adjust.As Fig. 1.In sum, it is feasible adopting reducing motor to revolve the branch mode.
2) screw connected tight fit device connector thread parameter is measured: pitch t=1.5mm; Tooth is counted z=9; Reach L=tz=13.5mm.
3) screw connected tight fit device connector screw thread revolves branch moment of torsion M SurveyMensuration: revolve the branch moment of torsion for the maximum of determining screw connected tight fit device, the screw connected tight fit devices that adopt digital torque spanner respectively 100 joint stocks, 100 joints to be reclaimed (part corrosion) have carried out screw connected tight fit device connector screw thread and have revolved separating tests.Result of the test shows, the screw connected tight fit device of stock revolve the branch moment of torsion generally between 39.2~98.8Nm, peak torque is 145Nm; The screw connected tight fit device of corrosion revolves the branch moment of torsion between 45~110Nm, and wherein the screw connected tight fit device of joint corrosion maximum is revolved the branch moment of torsion and reached 158Nm, measures moment of torsion M by maximum during calculating Survey=158Nm calculates.
4) screw connected tight fit device connector revolves drafting of branch rotating speed: screw connected tight fit device cylindrical shell and screw connected tight fit device connector are with being threaded, the thread seal place scribbles fluid sealant (lacquer), and the effect of revolving the branch facility is with screw connected tight fit device connector screwing.Must consider two conditions when determining to revolve component velocity: the one, the reducing motor rotating speed can not be too high, screw connected tight fit device connector screw thread revolves component velocity when too fast, the screw thread friction will produce bigger heat energy, unfavorable to blasting explosive secure, or in the violent friction of screw thread contact surface generation, cause thread form to damage, the reliability that influence splits; The 2nd, the reducing motor rotating speed can not be low excessively, otherwise can influence fractionation efficient, can not satisfy screw connected tight fit device and split the requirement of automatic production line technical indicator regulation.
5) the screw connected tight fit device connector calculating of revolving the branch rotating speed

Split the screw connected tight fit device of 5 joints in per minute, per hour should split 300 joints, so the opening, stop 600 times, f of motor per hour Ac=600.
The technical data that provides according to producer, when start and stop per hour 500~720 times, application factor f AcUsually get 1.25.
Actual condition coefficient f ACalculating: with f Ah, f AcSubstitution formula 3-2 gets
f A=f Ahf Ac=1 * 1.25; f A=1.25<f B=2.1, reducing motor actual condition coefficient f ALess than coefficient of utilization f B, meet the instructions for use of reducing motor.
7) revolve branch reducing motor type selecting: when selecting reducing motor, must satisfy requirement of explosion proof, rated speed and nominal torque meet the designing and calculating requirement, possess the intensity height simultaneously, volume is little, noise is low, efficient is high and characteristic such as long service life.
According to market survey, we select domestic comparatively advanced GR series reducing motor, and its major parameter of this reducing motor is as follows:
Model: GR37-YB1.5-4P-11.83-M1; Motor model: YB 2-902-4; Rated voltage: AV380V; Rated power: 1.5Kw; Output speed: 118r/min; Output torque: 82Nm; Gearratio: 11.83; Coefficient of utilization f B: 2.1.
8) revolve branch time t ReasonCalculating: 9/118=t Reason/ 60 (3-3)
In the formula, 9: ridge number (revolving the branch revolution is 9 commentaries on classics); 118: reducing motor rotating speed r/min; t Reason: revolve the branch time (second); 60: calculate by one minute (60 seconds);
3-3 gets by formula: t Reason=4.58 (seconds)
4<t Reason<5 seconds, meet t Reason=4~5 seconds designing and calculating requirement.
