November 23, 1966 Pulley for a reverse starter

The invention relates to a rope starter for internal combustion engines, in particular to a return rope ™ starter with a spring for rewinding the starter rope on the pulley.

So-called "flyback" type rope starters are used extensively in small internal combustion engines to provide cranking and enabling the engine to be started by pulling the rope. Basically there is a reverse starter made of a pulley that during the crank leg can optionally be connected to the motor. There is a starter rope on the pulley winds and thereby results in a rotary movement of the pulley by unwinding the rope from this to one Cranking the engine. A spiral spring is connected to the belt pulley and is wound up when the motor is cranked

ο and when the voltage is removed in the starter

to rope unwinds in order to wind the starter rope back onto the pulley. Several problems exist with continuous starters Biioko, one of which is that the at Startereeil at the connection point with the pulley

frays, so that the rope after a certain time

at this point it rips. This rope break usually occurs when the starter rope is being cranked is stretched, ao that the rewinding spring moves the pulley very quickly in the rope rewinding direction to over the can rotate out of its normal position, which usually results in the rewind spring breaking.

Another common difficulty encountered with rewind starters consists in the starter rope seizing up on the pulley. In the normal version is the pulley provided with a groove for receiving the rope, the width of which only slightly exceeds the rope diameter. Thus, when the rope is wound onto the pulley, it forms a spiral in which the adjacent turns in a radial direction Direction are wound on each other. When the starter rope is in the pulley groove and the motor is in the point extreme compression is within its work cycle, then, as a result of a sudden pull exerted on the starter rope, the outermost rope turn often slides in the area of the Point of contact of the rope with its turn radially inward and wedged between the next lower turn and one side of the pulley forming the rope groove. This radial displacement of the starter rope leads to seizure of the rope, so that very high tensile forces are then required in the starter rope to crank the machine, which is often the case a sharp bump and detachment of the starter rope and result in injury to the operator can.

The shape of the anchoring * ö of the spring in the housing is at the beaten from Fig. 4 eraiohtlioh. The anchorage has an axially extending edge 126 which cooperates with the inner end 106 of the spring as shown in dashed lines on the right in FIG. 5. In this regard, a positive connection between the spring 104 and the housing 10 is achieved when the spring is wound up while the engine is being started or is unwound when the starter rope is looking at the pulley. The spring anchorage 28 is also provided with an inclined end 128 which is offset radially near inward with respect to the edge 126. Thus, a | relative rotational movement of the pulley 38 in the clockwise direction (FIG. 5) relative to the spring anchorage beyond the point at which the spring end 106 is normally acted upon in cooperation with the edge 126, a detachment of the spring from the anchorage edge 126. The armature end 128 engages the band section 120 of the spring and bends the inner end 106 of the spring radially near the outside into the position shown on the left in FIG. 5 in dashed lines. Its unique clockwise rotation of the pulley relative to the spring anchor allows the inner end of the spring to wrap around the annular shape of the spring anchor 28 without the tendency to coil the reverse spring in the wrong direction and break or flex the spring to cause. The position of the spring end 106 shown in full drawn lines (shown in FIG. 5) is the position of the spring end in which the strap and spring assembly are assembled on the bolt 30. The distance between the edge 126 and the end 128 is dimensioned such that that

can be included in it and so the Proper installation of the pulley in the housing. The inner end 106 of the spring is constantly in engagement with the anchoring rim 126, as shown in Pig. 5 is shown.

In operation, the components are assembled as shown in Figure 1, and the spring 104 is "preloaded ^11" by approximately one turn to maintain the pretensioning effect on the starter rope when the handle 102 is in engagement with the socket 24 When the engine is started, the operator pulls the handle 102, which sets the pulley 3β in rotation. As a result of the resistance of the cable actuation cap 74 caused by the spring 78, an initial rotation of the Siemens disk occurs relatively smoothly Coupling claw 74 in the Torah that the coupling claw is pulled out of the position shown in 11g · 6 in dl * in Tig. 7 and the pulley is connected to the engine wheel cap Ö4 · Continued * rotation of pulley 38 When the engine starts, the clutch pawl 84 begins moving faster than the pulley 38 and the pawl 80 counterclockwise to rotate igersinne (Pig x 7) · Sine such movement the pawl 80 due to the motor cap causes a slight rotation of the claw ⁱ actuation cap 74 sum retraction of the end 88 of the claw aui the EotoAapp ·.

As soon as the torsion spring Ö6 acts on the inside of the claw end Ö8, it stops this spring the Beatand parts in the relationship shown in FIG and prevents the claw from inadvertently interacting with the engine door due to the vibration.

In order to achieve the objects of the invention with respect to the relationship between the pulley and the starter rope, there is a clear relationship between the pulley, the shape of its rope groove, and the starter pulley 24. In FIG. 12, the maximum width of the hat 56 is represented by the distance which separates the surfaces 6U and 64 from one another. This width is about 2 1/2 times the diameter of the starter rope in a normal, untensioned condition. The distance between the flute surfaces 6C and 62 is essentially equal to twice the diameter of the starter rope, the axial. The distance from the -3 surface 62 to the surface 64 is approximately equal to half the diameter of the start r'jeiles. The pulley 38 and the starter rope bushing 24 are related to one another such that the center of the bushing bore Zc lies in a plane which is equidistant from the pulley groove surfaces 60 and 64 between them.

He already mentioned is the hole 68, which is the inner The end of the starter rope takes up, in the area of the rope surface 62 arranged «Thus the inner end of the starter rope 98 lies in the area of the surface 62. FIG. 8 shows

the relationship of the starter rope to the pulley when the starter rope has been pulled substantially to its extreme position. In the position shown in FIG. 8, the starter rope rests essentially tangentially on the inner surface 58 of the groove 56. As soon as the pulley rotates back from the position shown in Fig. 8 position, the starter rope is placed on the pulley surface 58, so that the starter rope has a small distance from the Futenoberfläche 62, of FIG. 9 seen iat ₀ The arrangement of the starter rope on the Surface 58 is due to the fact that the center of the socket bore 26 is closer to the plane of the surface 60 than the center of the bore 68 for the starter rope by a distance substantially equal to half the radius of the rope cross section. *

As soon as the pulley 38 makes its first rotation during the Rücklauftätifckeit ended, the deil partially overlaps the Section of the starter rope that enters the bore 68. However, since the center point of the socket 24 with respect to the The center of the bore 68 is towards the plane of the surface 60, the section 130 of the starter rope, as well as it the rope section 132 meets, to the groove surface 60 distracted. This relationship is shown in Fig. 9 » Thus, during the second rotation of the pulley 38 during the return process, the starter rope 98 is on the surface 58 deposited in the area of the flute surface 60. As soon the second turn of the rope is picked up on the surface 58, she pushes in the first turn of rope on the pulley axial direction, so that it comes into cooperation with the groove surface 62.

When "two turns of rope have been wound onto the pulley 38, then the beginning of the third turn lies over the beginning portion 130 of the second turn, as shown in Figure 10. Since the center of the bushing 24 is closer to the plane of the surface 62 is at the plane of surface 60, when the third turn moves over the second, as shown in Figure 10, the rope is sighting for alignment with the bay or depression between the first and second turns pulled on the rod surface 50. Thus, the third turn d of the rope is held on the first and the second turn in the_Yon they formed 2YaI or the bay they formed.

Upon completion of the third turn of the starter rope wound on the pulley, the rope section 134 _f, which represents the beginning of the fourth Y / ind turn, engages the inclined rope section 136 of the third turn, the third turn entering the bay of the first and second turns. Thus, due to the presence of the inclined rope section 136 and because the center of the bore 26 lies between the surface 64 and the center of the third turn, the fourth turn is deflected by the third turn in the direction of the groove surface 64 and thus the fourth / turn wound onto the pulley between the third turn and the surface 64 and partially received on the radial shoulder 66,.

In Fig. 12 the first turn on the pulley is at A, the second at B, the third at 0 and the fourth at D-shown.

When the starter rope wäÄ '^ r: ³ boosting is pulled "then consists of the fourth turn of the ITeigung to move radially inwardly. In addition, the tension on the starter rope reduces the diameter somewhat, as the rope fibers are compressed. However, the radial inward movement of coil D is prevented because this coil is held on shoulder 66 and coil A. If the winding D is unwound during cranking of the pulley, then the coil C picks up tension forces, and movement of the coil C radially inward is prevented since this turn of the windings A and B gehai * "th iat and Bay is stuck between them. Since the dimension between the Nutenoberfläeken 60 and 62 corresponds substantially to the double Durohmesser of the rope 98, the coils A and B, a motion can not move axially to the V, ^r indung C to permit radially inward. The turn C thus retains its position while the cable forces exert a tensile effect on this turn.

The bottom two turns of the crank on the pulley occur when turns B and A are unwound. Since these turns are received directly on pulley groove surface 58, radial movement of these turns is prevented. '
