Abstract
The utility model relates to a spring starter for internal combustion engines. The utility model is composed of a winding up mechanism, a starting control mechanism, an automatic position-limit mechanism and an automatic separartion mechanism. The lower part of the shift rod of the automatic position-limit mechanism is additionally provided with a manual auxiliary clutch device. An eccentric wheel is changed into an eccentric circular ring. The manual auxiliary clutch device is adopted, the preset position of the shift rod and the eccentric circular ring is thorough separated, the abrasion of the shift rod is avoided, and the service life of the shift rod is extended. As the eccentric wheel is changed into the eccentric circular ring, the contact of the eccentric circular ring and the shift rod is stable, and the mechanical shock is not generated in operation. Through the improvements, the utility model obviously improves the failure free operation time.
Description
The utility model belongs to the starting arrangement of internal-combustion engine, is specifically related to a kind of mechanical type internal-combustion engine clockwork spring starter motor.
At present, the non-power starting arrangement of small-power internal-combustion engine uses the comparatively convenient and reliable mechanical type clockwork spring starter motor that has.As utility model patent 95211633, the 96202460 internal-combustion engine clockwork spring starter motors of having authorized, can be used for the starting of agricultural motor tricycle, tractor with small four wheels, engineering dump car, farmland discharging-irrigating equipment, changed the behindhand type of small-power internal-combustion engine by artificial hand starting.But above-mentioned starter motor remains in the some shortcomings part: position-limit mechanism automatically 1, winds up, though can separate with eccentric wheel driving lever in the precalculated position automatically, reach spacing purpose, separate thoroughly inadequately, driving lever and eccentric wheel still are in slight weak Frotteurism, cause the driving lever abrasion.2, eccentric working surface is made of two sections bigger arc surfaces of diameter difference, and it is bad that arc surface is connected transition, easily produces mechanical shock in the running, and influence is turned round steadily and working life.
The purpose of this utility model is at above deficiency, and a kind of improved internal-combustion engine clockwork spring starter motor is provided.The driving lever of this machine can thoroughly separate in the precalculated position with eccentric wheel, improves working life; Driving lever and eccentric wheel do not have machinery in the course of the work to be impacted, turns round steadily.
Technical solution of the present utility model is:
Internal-combustion engine clockwork spring starter motor is made up of remontoir, starting control mechanism, automatic spacing mechanism and automatic-separation mechanism, the utility model is set up a manually auxiliary engaging and disengaging gear below the driving lever of automatic spacing mechanism, this device is made up of little axle, clutch handle, eccentric mass and spacing backing pin, little axle is installed on the starter housing, clutch handle places little axle outer end, eccentric mass places little axle inner, and spacing backing pin is positioned at eccentric mass one side.The utility model also is that the eccentric wheel of two sections circular arcs changes an eccentric annulus into former working surface, and eccentric annulus still is arranged on clutch plate one side.
The outer round surface of above-mentioned eccentric annulus, a side and clutch plate cylindrical are tangent, and opposite side and clutch shaft are tangent.
The utility model can make driving lever thoroughly separate in the precalculated position with eccentric annulus after adopting manually auxiliary engaging and disengaging gear, has avoided the wearing and tearing of driving lever, has prolonged working life.Change eccentric wheel into eccentric annulus, make driving lever and eccentric circle loop contacts steady, do not produce mechanical shock in the running.By above improvement, significantly improved the Mean time to failure of internal-combustion engine clockwork spring starter motor.
Further describe the utility model below in conjunction with accompanying drawing:
Fig. 1 is an internal-combustion engine clockwork spring automotive vehicles structural representation.
Fig. 2 is spacing mechanism structure schematic representation.
As shown in Figure 1, 2, the utility model is by the remontoir that is arranged in the housing 15, and starting control mechanism, position-limit mechanism are formed.Remontoir comprises: small gear 7, gearwheel 16, clockwork spring 17, hollow shaft 5, one-way element 2, Large Gear Shaft During 10 and driving lever 3.The starting control mechanism comprises: hollow shaft 5, starting lever 1, locking ball 6.Position-limit mechanism comprises: dial 14, limit cam 18, sheave 19, stationary axle 20, eccentric annulus 11, little axle 29, eccentric mass 32, clutch handle 30, clutch handle backing pin 31.
Use first by manually winding up.Rotate hollow shaft 5 with crank 8, drive small gear 7 and gearwheel 16 rotations,, finish the energy storage that winds up first clockwork spring 17 rolling-in by hollow shaft 5.
During starting, depress starting lever 1, locking ball falls in the hollow shaft groove, small gear separates with hollow shaft, clockwork spring releases energy, drive the gearwheel backward rotation, and by free wheel device 12 drive engine spindle rotations, when spindle speed was higher than the rotating speed of clutch shaft 9, clutch was in and surmounts state, finishes starting process.
After the starting, starter motor begins the automatic spacing energy storage again, recoils and wind up.After starting lever 1 resets, by locking ball 6 small gear and hollow shaft are locked, driving lever 3 is pressed on the eccentric annulus 11 by torsion spring 4, eccentric annulus rotates synchronously with clutch and main shaft, and the drive driving lever swings back and forth, the small gear one-way rotation drives gearwheel 16 rolling-in clockwork springs simultaneously under the effect of one-way element 2, at this moment, dial 14 rotates with Large Gear Shaft During 10, stirs sheave 19 transpositions by dial straight pin 13, when dial turns around, sheave turns over 60 °, changes 5 circles and finishes energy storage if set clockwork spring, and dial stirs that sheave is corresponding to turn over 300 °, at this moment limit cam 18 is with driving lever 3 jack-up, driving lever is separated with eccentric annulus stop to wind up, at this moment, clutch handle 30 is rotated forward, the off-centre of clutch handle eccentric mass 32 rises the jack-up driving lever, so far finishes thorough separation.When starting once more, the clutch handle that rotates backward, clutch handle eccentric mass off-centre falls, and under torsion spring 4 pressure, driving lever resets and is pressed on the eccentric annulus, depresses starting lever 1 starter motor and promptly repeats said process.
Claims (2)
1, a kind of internal-combustion engine clockwork spring starter motor, form by remontoir, starting control mechanism, automatic spacing mechanism and automatic-separation mechanism, feature of the present utility model is to set up a manually auxiliary engaging and disengaging gear below the driving lever of automatic spacing mechanism, this device is made up of little axle, clutch handle, eccentric mass and spacing backing pin, little axle is installed on the starter housing, clutch handle places little axle outer end, and eccentric mass places little axle inner, and spacing backing pin is positioned at eccentric mass one side; With former working surface is that the eccentric wheel of two sections circular arcs changes an eccentric annulus into, and eccentric annulus still is arranged on clutch plate one side.
