Abstract
The utility model discloses a ratchet one-way starter clutch. The one-way clutch is composed of an outer shell, a drive casing tube arranged in the outer shell, a drive gear arranged on the drive casing tube and a ratchet wheel. The ratchet one-way starter clutch is characterized in that the inner wall of one end of the drive casing tube is provided with a helical spline. The operating principle is that the helical spline can generate an axial force to assist a shifting fork to work, the service power of an electromagnet switch can be decreased, and the volume of the electromagnet switch can be decreased. Because the utility model can effectively decrease the service power of the electromagnet switch and the volume of the electromagnet switch, the volume of the whole starter can be greatly reduced and the cost can be correspondingly lowered. The ratchet one-way starter clutch has a good developing prospect.
Description
Technical field
The utility model belongs to the starter motor field of explosive motor, refers more particularly to a kind of manufacturing of overrunning clutch.
Background technique
Overrunning clutch is in the engine starting process, thereby gives a kind of equipment that starts to realize engine start with the energy transfer of starting electrical machinery.Overrunning clutch is stirred overrunning clutch by shift fork when the adhesive of Starter magnetic switch, make the engagement of overrunning clutch gear and motor gearwheel, ato unit, and after startup was finished, the overrunning clutch gear was thrown off from the gearwheel on the motor.In order to guarantee that the overrunning clutch gear is thrown off from the gearwheel on the motor, often a return spring that elastic force is bigger need be installed in overrunning clutch.In order to overcome the compressive tension of this return spring, require selected magnetic switch also will have the suction that equates therewith, this has just brought the required problem that magnetic switch power is higher, volume is excessive.
Summary of the invention
The purpose of this utility model is to provide a kind of overrunning clutch that can reduce the magnetic switch volume greatly and use power.
The utility model is realized by following manner: a kind of overrunning clutch, and by shell, be installed on the drive sleeve in the shell and the actuation gear and the ratchet group that are loaded on the drive sleeve constitute.It transforms thinking: set about from the tension force that reduces the shift fork spring on the starter motor, with this use power that reduces magnetic switch, reach the purpose that reduces the magnetic switch volume.The inwall that drive sleeve is connected an end with motor shaft is processed into helical spline, the armature shaft of motor becomes spline to cooperate with it equally, so that electric motor starting when rotation, on helical spline, produce an end thrust, auxiliary shift fork is pushed ahead the overrunning clutch sleeve pipe, behind engine start, the big flywheel rotating speed of motor is much higher than the rotating speed on the actuation gear, at this moment again can be by the friction on the ratchet group, on helical spline, produce the axial force of a post-tensioning, overrunning clutch is pulled back rapidly, so just can significantly reduce the spring tension on the shifting fork bar, realize reducing the purpose of magnetic switch power and volume.
Because the utility model can reduce the use power of magnetic switch effectively, and has dwindled the volume of magnetic switch, and starter motor volume integral body is dwindled greatly, and the also corresponding decline of cost, has good DEVELOPMENT PROSPECT.

Embodiment
Steel pipe is processed into drive sleeve 3 according to required size, and the outer wall of drive sleeve 3 one ends is processed into the spline that cooperates with actuation gear 5, processes helical spline 1 on the inwall of the other end, is connected with the armature shaft of starter motor with this.Pack into successively on drive sleeve 3 then ratchet group 4, actuation gear 5, the shell 2 of at last drive sleeve 3 and other parts together being packed into forms free-wheeling assembly.When overrunning clutch was assembled to starter motor, an end that is had helical spline 1 by drive sleeve 3 inwalls was connected with the armature shaft of starter motor, and 5 of actuation gears cooperate with engaging tooth on the big flywheel of motor.When the machine operation on the starter motor, the rotation of armature shaft just can produce the end thrust that an actuation gear 5 on the promotion overrunning clutch cooperates with engaging tooth on the big flywheel of motor, and behind the engine start, the friction that on the ratchet group 4 on the overrunning clutch, produces when then utilizing big flywheel fast rotational, produce the axial force of a post-tensioning on helical spline, the pulling overrunning clutch hightails big flywheel.
Claims (1)
1, a kind of ratchet-type starter motor overrunning clutch, by shell (2), be installed on the drive sleeve (3) in the shell (2) and be loaded on actuation gear (5) and ratchet group (4) formation on the drive sleeve (3), it is characterized in that the inwall of drive sleeve (3) one ends is provided with helical spline (1).
