Wherein, detecting system 30 described in the utility model includes torque sensor 34 and velocity sensor 35.AKC205 selected by described torque sensor, selects Type B, and the operation principle of torque sensor is as follows: use electric measurement technique of strain gage, forms strain bridge on elastic shaft, provides power supply can record the signal of telecommunication that this elastic shaft is turned round to strain bridge.After being amplified by this strain signal, through overvoltage/frequency conversion, become the frequency signal being directly proportional to torsional strain.The operation principle of described velocity sensor is as follows: tachometric survey uses the method for magnetoelectricity code-disc to measure, each magnetoelectricity code-disc all has 60 teeth, axle drives magnetoelectricity code-disc often to rotate a circle can produce 60 pulses, rotating speed accurately can be measured by the method in the cycle of survey by the method for frequency measurement during low speed sampling when high speed or middling speed sampling.This sensor accuracy up to ± 0.1%～± 0.5%(F S).Owing to sensor is output as frequency signal, so computer can be fed directly to without AD conversion carry out data process.
Wherein, described rotating shaft 33 is coupled by shaft coupling by many shaft parts.Shaft coupling is that in order to reduce the vibration of machine driven system, reduce impact S.acus Linnaeus exact, shaft coupling also should have certain bumper and absorbing shock performance by axially coupled for two axles and transmit moment of torsion and the parts of motion and have certain ability compensating parallel offset.Shaft coupling the most also has Overload Protection effect concurrently.The type of shaft coupling includes positive coupling, flexible coupling, safety coupling.Positive coupling does not have compensation and is joined the ability that two axle axis offset relatively, does not the most have bumper and absorbing shock performance；But simple in construction, low price.Only steady in load, stabilization of speed, can guarantee that joined two axle axis relatively offset minimum in the case of, just can be selected for positive coupling.Flexible coupling has certain compensation and is joined the ability that two axle axis offset relatively, and maximum is different with model difference.Safety coupling feature structurally is, there is insurance link (such as pin movably connection etc.), and it can only bear limited load.When real load exceedes the load limited in advance, insurance link just changes, and blocks the transmission of motion and power, thus protects the remainder of machine to damage, i.e. plays safeguard protection effect.Shaft coupling uses fixed rigid coupling herein.Compared with other fixed rigid couplings, flange-face coupling simple in construction, easy to manufacture, reliable operation, easy to assembly, good rigidly, transmission torque is big, but can not absorb impact.It is applicable to the general transmission of stable working, needs high to neutralizing the accuracy of manufacture during high-speed drive.Therefore using this shaft coupling as the shaft coupling of link engine shaft with torque-transmitter shaft, model is GY type.
Wherein, the operation principle of described starter 37 is as follows: the operation principle of starter can be illustrated by the operation principle of its critical piece dc motor.Dc motor is the equipment converting electrical energy into mechanical energy, and it is to be made by based on this principle of electromagnetic force in magnetic field according to energized conductor.Its operation principle is as shown in the figure.Torque produced by a coil is the least, and rotary speed unstabilization is fixed, therefore it practice, be wound with a lot of coil on the armature of motor, and number of segment also increasing and increase accordingly with coil.Thus ensure to produce sufficiently large torque and stable rotating speed.Auto electric has two crucial parts, and one is electromotor, and responsible automobile is powered；Another is starter, is responsible for vehicle starting.Both motors equally have magnetic field, armature and rectifier cell, but the former is to convert mechanical energy into electric energy, and the latter is to convert electrical energy into mechanical energy, and therefore both structures are to have the biggest difference.The effect of starter is as follows: make engine crankshaft be changed into kinestate by resting state, it is necessary to lodge external force, resistance during customer service engine start, minimum speed required during to reach engine start.Starter described in the utility model uses the starter of car electromotor.
Wherein, described rotating shaft 33 is arranged in axle sleeve 32 by bearing.Bearing can be divided into rolling bearing, radial bearing, ball bearing, thrust bearing etc..Should be to support from the point of view of studying carefully its effect, i.e. literal interpretation be used for holding axle, but this is a part for its effect, supports its essence and can undertake radial load exactly.It can be appreciated that it is used to fixing axle.It is exactly that fixing axle makes it can only realize rotating, and controls its movement axially and radially.Motor does not has the consequence of bearing to be exactly can not to work at all.Because axle may move to any direction, and require that axle can only rotate during motor work.The effect of transmission can not be realized from theory, moreover, bearing also can affect transmission, must realize good lubrication on the bearing of high speed shaft to reduce this impact, some bearings itself have had lubrication, have been called prelubricated bearing, and most bearing must have lubricating oil, it is responsible for when running up, owing to friction not only can increase energy consumption, is more frighteningly easy to damage bearing.Bearing herein uses deep groove ball bearing.Compare other models, deep groove ball bearing simple in construction, easy to use, it is that production lot is maximum, the class bearing that range of application is the widest.It mainly bears radial load with one, it is possible to bear certain axial load.When the end-play of bearing strengthens, there is the function of angular contact bearing, bigger axial load can be born.And this bearing has simple in construction, easy to use, it is not required to maintenance during work, applies extremely wide grade a little.Model selects 60000 types, is 61914.
Wherein, the colyliform accumulator with relatively large rotating inertia that described flywheel 36 is mounted on rotary shaft of machine.The effect of flywheel is mainly: first, stores the energy of unnecessary and supplementary shortcoming, steady with the rotating speed keeping working machine, improves working condition and the work quality of engine.When the output torque of engine has cyclic fluctuation (such as diesel engine etc.), and when working machine has strict demand to the smoothness of rotating speed (such as the alternator etc. of parallel running), the effect of flywheel is even more important；Second, by allowing the rotating speed of flywheel have bigger lifting store and release energy, to reduce engine power demand.When working machine load has mechanical periodicity (particularly having of short duration peak) and rotating speed allows to have a greater change (such as stamping machine, forging press, cutter etc.), utilize flywheel can significantly decrease engine power demand, such as, one its motor power (output) of forcing press having flywheel is 50 kilowatts (kW), as without flywheel, then motor power (output) needs 600kW could meet the needs of pressure spikes moment of torsion.The structure of flywheel typically has board-like, plate spoke and spoke type 3 kinds.In order to alleviate the weight of machinery, flywheel is typically mounted on the axle that rotating speed is higher, and its Mass Distribution is away from rotation axis.Applying wider in production line is the spoked flywheel of big wheel rim and with the plate spoke flywheel of structural steel welding.Part assembled flywheel is used in the diesel engine of low-speed heave-load.Owing to bigger centrifugal force can be produced when flywheel rotates, so the linear velocity of flywheel to be limited during design flywheel.The peripheral speed of cast iron flywheel should be less than 25～35 meter per seconds, cast steel should be less than 50 meter per seconds, the flywheel peripheral speed of dish type cast steel should be less than 80 meter per seconds.
Above content is only better embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, the most all will change, this specification content should not be construed as restriction of the present utility model.
