Embodiment:

The utility model be by one three the combination housing (be upper casing 36, mesochite 15 and lower casing 16 usefulness bolts are connected and fixed) and wind spring 13 compositions that the axle with gearwheel 14 is a spool, Large Gear Shaft During uses Bearing Installation between mesochite and lower casing, in the middle of upper casing, one output shaft 37 is arranged through Bearing Installation, be fixed with a rotating speed in the outer end of body shell on the output shaft and control gear clutch, rotating speed control gear clutch is to fix in one to take turns 4 on output shaft, by bearing 1 foreign steamer 2 is installed on the interior wheel shaft skirt, be fixed with case 3 on the foreign steamer, be arranged with steel ball and key that spring withstands in the cover, cover is outside equipped with the spring housing 5 of Regulation spring pressure size and transfers silk 6.Output shaft in the upper casing inboard is one and recessedly takes turns 8, the one eccentric bearing of installing 9 is arranged above recessed the wheel, recessedly take turns external stability wheel cover 10 is arranged, be arranged with key 18 in the cover, the outer end of key 18 has pressure spring 17 to withstand on the wheel cover wall, the other end of key withstands in the inclined plane groove of the internal clickwork 19 that is contained on the Large Gear Shaft During, and Large Gear Shaft During can only clockwisely can not be reversed.Be provided with a dial axis 12 on the outer step edge of dial 11, dial axis is stirred the limit groove of sheave 22, and spring 20 and cam 21 are arranged on the fluted roller shaft.In combination shell one side an axle 27 energetically is installed, axle top is provided with free wheel device energetically, the outer surface groove that is with of wheel 26 in it, spring 24 and spring seat 25 that roller 23 and top roller are arranged in the groove, there is foreign steamer 33 in the roller outside, be connected with lever 7 on the foreign steamer, the torsion spring 32 that lever is fixed on energetically on the axle is pressed on the recessed capacity eccentric bearing of taking turns 9 of output shaft.There is steel ball 30 on the top in the symmetrical holes on the outer wall of axle bottom energetically, steel ball outside withstands on energetically axle and goes up in the groove in small gear 29 skirt sections of installing, the inside of steel ball withstands on energetically on the mandrel 31 that is withstood by stage clip 28 in the axle, the groove that loosens steel ball is arranged in the middle of the mandrel, have a push rod 34 to stretch out the starter shell on the mandrel startup depression bar 35 is installed.During installation, earlier the case 3 with the rotating speed solenoidoperated cluthes is installed on the belt pulley of diesel engine with one heart, and the combination shell of this starter is fixed on the front end of diesel engine by support, makes Pulley shaft concentric with output shaft 37 diaxons.When starting diesel engine, directly press down startup depression bar 35 with hand, depression bar is depressed mandrel 31 by push rod 34, steel ball 30 is moved in the groove of mandrel 31, at this moment, the gearwheel 14 that is meshed with small gear 29 on the axle 27 turns round under the effect of energy storage wind spring 13 energetically, and energy takes turns 8 through output shaft 37 drive diesel engine belt pulleys rotations by the internal clickwork on the gearwheel with the output shaft of its keyed jointing is recessed, starts diesel engine.Unclamp the startup depression bar after the startup, output shaft is recessed takes turns on 8 because the eccentric motion of the eccentric bearing of installing is arranged, by lever 7 energy is passed to energetically small gear (resetting steel ball automatically with small gear and shaft locking energetically owing to start lever) on the axle, small gear drive gearwheel rotates to wind spring energy storage again.When giving the wind spring energy storage, because the dial axis 12 that gearwheel drives on the dial is stirred sheave 22 rotations, the cam 21 when the energy storage is full on the sheave rotates jack-up lever 7, and the bearing of the eccentric installation of energy storage no longer acts on lever and promptly is stopped.After the startup, when the rotating speed of diesel engine reached the setting rotating speed, the rotating speed control gear clutch on the output shaft made key separate with output shaft because the centrifugal force of key overcomes the pressure of spring 3, and output shaft stops operating, reduce wear on the one hand, also make whole starter be in resting state simultaneously.
