Description
[technical field]
The present invention relates to the starter of diesel engine technical field.
[background technique]
Because traditional diesel engine manually boots mode, the hidden danger on problem that existence is wasted time and energy and the safety, therefore, people have just developed starter of diesel engine.Existing starter of diesel engine is divided into electrodynamic type and mechanical type two big classes, wherein DYN dynamic starter has caused the starter volume very large owing to will carry storage battery, the price height, the problem that breaks down easily makes people tend to use mechanical starter more.
The mechanical type starter of diesel engine can mainly be made up of clutch mechanism and stored energy mechanism, wherein clutch mechanism has connected the main shaft of diesel engine rotating shaft and starter, be used for realizing the function of the two clutch in good time, and stored energy mechanism adopts wind spring more is energy storage component, wind spring is around on the spring tube, it is different around turning to of spring tube in energy storage and the process that releases energy, but in order to realize winding up automatically, starter is after starting diesel engine, need utilize Diesel Driven to tighten wind spring in order to using next time, therefore the main shaft of starter is after driving diesel engine starting, continuation is rotated towards previous direction by the main shaft continuation of the rotating shaft drive starter of diesel engine and is realized winding up, and therefore the starter main shaft that is connected with diesel engine can only rotate by same direction in the wind spring energy storage and the process that releases energy.And prior art is in order to address the above problem, it as application number the automatic remontoir in 00112508.7 the disclosed technology of Chinese patent, it has comprised two one-way elements, several gears etc., complex structure, cause the starter volume big, use inconvenience, and when tightening wind spring for the first time, relatively require great effort.
[summary of the invention]
The purpose of this invention is to provide a kind of starter of diesel engine, it solves the main shaft of above-mentioned starter and turn to problem between the spring tube by the cycloidal-pin wheel principle, and it is simple in structure, and is convenient and strength-saving during use.
Technological scheme of the present invention is as follows: a kind of starter of diesel engine, comprise a housing, wind spring and an eccentric shaft, socket one is around the spring tube and pass housing on the eccentric shaft, wind spring is around on the spring tube, described eccentric shaft one end connects clutch mechanism, the other end socket starter receiver describedly is connected the duplex tooth around between spring tube and the starter receiver, and the outer number of teeth of duplex tooth is less than around the interior number of teeth of spring tube and starter receiver and be enclosed within on the eccentric shaft; The described circle one-way clutch tooth that also is provided with on spring tube inwall has a square groove on the eccentric shaft, be provided with one in the square groove by monolateral hardware piece of upspringing, and described hardware piece is against on the described one-way clutch tooth.
The duplex tooth is enclosed within on the eccentric shaft, eccentric shaft passes around the spring cylindrical shell, the duplex tooth meshes respectively with around the internal tooth of spring tube and the internal tooth of starter receiver, in the eccentric shaft rotation process, according to the cycloidal-pin wheel principle, when eccentric shaft rotates, since on the duplex tooth characteristics of tooth curve and be subjected to around the restriction of spring tube internal tooth so, the motion of duplex tooth becomes the plane motion that existing revolution has rotation again, so in the eccentric shaft rotation process, around spring tube backward rotation, thereby tighten wind spring.
When discharging the wind spring energy, wind spring drives around the counter-rotation of spring tube when tightening wind spring, direction when this moment, the one-way clutch tooth promotion eccentric shaft court in the spring tube tightened wind spring is rotated, because eccentric shaft has connected clutch mechanism, and clutch mechanism is the rotating shaft that has connected diesel engine, so just started diesel engine, and after having started diesel engine, under the effect of diesel engine rotating shaft, eccentric shaft continues to rotate along the direction that tightens wind spring, tighten process so just can repeat above-mentioned wind spring, after tightening wind spring, separate the rotating shaft of eccentric shaft and diesel engine by clutch mechanism.
Close by the hardware agllutination of upspringing on one-way clutch tooth in the spring tube and the eccentric shaft, make eccentric shaft when tightening wind spring, can independently rotate and drive around spring tube backward rotation by the cycloid principle, upspring owing to the hardware piece this moment, can paste the one-way clutch tooth rotates always, and when when the spring tube drives eccentric shaft, then the inclined-plane of one-way clutch tooth promotes the hardware piece, and then promotes eccentric shaft.Realized that eccentric shaft all rotates according to a direction all the time, and structure is simple relatively in the wind spring energy storage and the process that releases energy.
As a further improvement on the present invention and optimize, the present invention takes following measure:
The described bar-shaped trough that on the spring drum outer wall, has, described wind spring one end is stuck in the bar-shaped trough, and the other end is fixed on the housing.
Described starter receiver is made up of the hollow cylinder of two different-diameters, and small diameter cylinders stretches into described in the spring tube, and large diameter cylinder has a plurality of vees and is exposed at outside the described housing.The control of starter receiver by opposing connection spring tube comes reality to the startup of starter with close, and its part extend into and makes that in the spring tube the two connection is more firm, controls more effectively, and the vee of leaving is used for cooperating the outer controlling component of starter.
Described vee has three and be distributed on the outer wall of described cylinder with large diameter.
Described duplex tooth is made up of the gear of the different numbers of teeth of two different-diameters, and the gear of its medium-small diameter is connected with starter receiver, gear wheel in large diameter be connected around the spring tube.Because a starter receiver part extend in the spring tube, therefore need the duplex tooth to do corresponding improvement and cooperated.
Square groove bottom on the described eccentric shaft is provided with a circular hole, and spring is set in the hole, and described hardware piece is pressed on the spring.
Be provided with the complex root needle roller between described eccentric shaft and the duplex tooth.Needle roller is set, reduces the friction between eccentric shaft and the duplex tooth.
Compared with prior art, outstanding advantage of the present invention is: by cycloid needle roller principle, design eccentric shaft and the annexation between the spring tube, and the hardware piece of upspringing on the one-way clutch tooth cooperation eccentric shaft is being set in the spring tube, realized that eccentric shaft all rotates according to a direction all the time, has simplified the starter structure in the starter energy storage and the process that releases energy, reduce the volume and weight of starter, made things convenient for use.
