Definitions
- the present invention relates to a procedure at and a device for a rope winch, embodying a rotatably mounted rope drum and a shaft driving the same via a transmission, around which drum a rope is windable, as well as forcing means, such as a crank, for allowing the rope drum to be driven by means of the driving shaft in a first direction using at least two different gearings.
- rope winches are found in sailing boats and are there used to, among other things, adjust the sails by means of sheets, i.e., ropes, which ensure to keep a sail at a fixed angle in relation to the current wind, and by which it is possible to determine, adapt, the speed at which it is desired to sail.
- sheets i.e., ropes
- the wind does not always blow in such a direction that it is possible to sail in the most convenient possible manner, but for allowing sailing with the wind in all directions in relation to the boat, from upwind to downwind, something has to be done.
- the purpose of the invention is attained by a winching out of the sheet to an adjusted extent being allowed by the fact that means in/on the crank are actuated at the same time as cranking is carried out, a drive gear of the transmission, which in the normal case drives in the same direction as the cranking direction, by means of forcing means being brought out of driving engagement with the input shaft, the torque applied to the input shaft instead being used to release the drive gear from driving engagement in such a manner that the driving coupling between the crank and the transmission is temporary disabled to transfer torque, wherein rope wound on the drum of the winch can run out under load.
- the drive gear of the transmission is brought out of driving engagement by a not self-locking cone coupling being released.
- a not self-locking coupling makes that the coupling always will release in a smoothest possible manner if it is manoeuvred to make this.
- Fig. 1 shows a perspective view of a crank of a winch
- Fig. 2 shows a perspective view of a drive shaft having transmission for a winch in a first state
- Fig. 3 shows a perspective view corresponding to Fig. 2 partly as a cross-section and in the same state
- Fig. 4 shows a perspective view that essentially corresponds to Fig. 2 but in a second state
- Fig. 5 shows a perspective view in cross-section corresponding to Fig. 4,
- Fig. 6 shows a cross-section through an alternative design of a crank in comparison with the design according to Fig. 1 ,
- Fig. 7 shows a perspective view of a drive shaft and parts of a transmission having a double cone coupling, shown with the parts apart, and
- Fig. 8 shows a perspective view of a winch drum for the implementation of the procedure and the device according to the invention.
- Fig. 1 shows as a perspective view a design of a winch crank 1 for a winch L (refer to Fig. 8), which crank embodies a hub 2, a lever 3 as well as a handle 4.
- a button 5 of circuit breaker type i.e., a button having two individually stable steady positions, which also may be called a mechanical bistable trigger.
- Fig. 2 shows a view of a drive shaft 6 including transmission 7, 8, 9, 10, 11 , 12, 13, 14 of a winch in a first state.
- first state it is meant that a drive gear 7 is in a position in which there is no mutual contact between freewheel teeth 8a on the underside of the drive gear 7 and the corresponding teeth 8b on a driver 9 (more clearly shown in Fig.3), respectively.
- a ratchet wheel 10 and a ratchet rider 10b spring biased against the same.
- the output shaft 11 of is integral with a pinion 12 for the driving of a second gear by the wheels 13, 14 of the winch A.
- Fig. 3 shows a picture of the drive shaft 6, including the transmission 7-14, represented as a partial cross-sectional view.
- the plunger 15 has a driving rod 16 pushed on, which in turn is inserted in a slide 17.
- the driving rod 16 telescopes into the slide 17, which has two radial holes 18, in which pins 19 are arranged. The pins project under the impact of the driving rod 16 through the holes 18 and stick into slots 20 in the drive shaft 6.
- the reason for arranging the pins in this way is that it should be possible to mount and dismount, respectively, the parts.
- an additional compression spring 21 b is attached, which presses, on one hand, against the slide 17 while it has the holder- on thereof in a sleeve 22 that is framed in a cylindrical recess 23 in the output shaft 11 of the pinion 12.
- the shaft 11 of the pinion 12 has, at the end thereof opposite the pinion 12, a trapezoidal thread 24a having a pitch of between 25 and 35°, preferably closer to 30°.
- the trapezoidal thread 24a co-operates with an opposite trapezoidal thread 24b on an inner cone 25 of a double-cone coupling 26, which, depending on the tightening state of the trapezoidal thread, either is intended to transfer a torque or is intended to take care of temporary avoiding the same.
- the double-cone coupling 26 embodies an intermediate cone 27 as well as an outer cone 28, on the outside of which there are arranged ratchet teeth 29, which are intended to co-operate with a pair of ratchet riders 10b acting spring-biasedly against teeth 29 of the principally cylindrically shaped outer cone 28. From this figure, it is also seen how the input shaft 6 has a driving driver provided with driving teeth 32 that are in driving engagement with the corresponding teeth of the intermediate cone 27, as well as that between said parts, there is a spiral compression spring 31 arranged.
- Fig. 4 shows a perspective view that essentially corresponds to Fig. 2 but in a second state in which the teeth 8a, b are in engagement with each other.
- the ratchet wheel 10 co-operates with the spring-biased ratchet rider 10b thereof and permits the wheel 10 to rotate only in clockwise direction.
- Fig. 5 shows a partly sectioned perspective view in an engagement state corresponding to the one according to Fig.4.
- the plunger 15 is depressed, which results in the driving rod 16 and the slide 17 including the pins 19 projecting through the cylindrical outer periphery thereof forcing the freewheel teeth 8a, b of the drive gear 7 into engagement with each other.
- Fig. 6 shows a cross-section through an alternative design of a crank in comparison with the design according to Fig. 1.
- the crank has a handle H, and according to this design, the manoeuvring is effected by an insertable and projectable plunger 36 in the engagement part 33 of the crank, here provided by means of a button 35 spring biased toward an unactuated state. Upon pressing, the button 35 actuates a lever 34 and, in that connection, lifts an actuator 45.
- Fig. 7 shows a perspective view with the parts separated of the drive shaft 6 including appurtenant parts of a transmission 7-14, which includes the double cone coupling 26, having the inner cone 25, the intermediate cone 27 as well as the outer cone 28 on the inside of the ratchet wheel 10.
- the initial position is that no winch crank 1 is attached in a recess 33 arranged for this purpose in the drive shaft 6 shown in drawing Figure 1 and provided with drive splines.
- the force from the spring 21 b is greater than the one from the spring 21a and, accordingly, simultaneously forces the slide 17 to be lifted maximally, which results in the teeth 8a, b of the floatingly mounted gear wheel 7 and drive shaft 6, respectively, being brought out of engagement with each other and, accordingly, no torque being able to be transferred from the gear wheel 7 to the winch drum (refer to Fig. 8).
- a possible subsequent state is that the winch crank 1 is attached in the splined engagement part 33 of the drive shaft 6.
- the hub 2 of the winch crank 1 has a male spline 37, which mates the engagement part 33 of the drive shaft 6, and which in this "default state” thereof acts on the plunger 15 to be pressed downward until the slide 17, including the pins 19 attached in the radial holes 18, which pins are in engagement with the slots 20 on the inside of the gear wheel 7, presses down the gear wheel 7 in such a way that a mesh is established between the teeth 8a on underside of the gear wheel 7 and the teeth 8b on the upperside (as seen in the figure) of the driver 9.
- the winch works as a conventional two- speed winch, where the gear wheel 7 in this case represents the first gear, the gear wheel 12 together with the gear wheel 13 represents the second gear, where the wheel 13 drives directly on a gear rim on the inside of the winch drum.
- a clockwise cranking now means that the first gear is driven via the teeth 8b of the driver 30 and transfers the torque to the gear wheel 7 via the teeth 8a.
- a counter- clockwise cranking accordingly causes the double-cone coupling 26, by the fact that the trapezoidal thread 24a, b integrated thereby is turned in such a way that it disengages the grip thereof and thereby releases the coupling in such a way that force and torque is transmitted down to the drive gears 12, 13 and finally 14 in the winch, to provide a second gearing.
- Another state is the one that arises with the crank 1 mounted but in which simultaneously either the button 5 on the hub 2 of the crank or the corresponding button 35 on the handle H of the crank (refer to the design according to Fig. 6) is pressed in order to get a plunger in the crank hub 2 to be lifted a short distance
- the ratchet has the purpose of preventing the winch from rotating "rearward" under the impact of a torque M2 that is applied to the winch drum 38 (refer to Fig. 8) from a stretched rope 45, for instance a sheet connected to a sail. M2 strives to try to turn the pinion wheel 12 counter-clockwise. The torque M2 is transmitted to the trapezoidal thread 24b on the shaft 11 of the pinion 12, which in turn transfers the torque to the inner cone 25.
- the instant invention relates generally to a procedure at and a device for a rope winch L of the kind shown in Fig. 8.
- a winch L embodies a rotatably mounted rope drum 38 around which the rope 45 is intended to be wound.
- a drive shaft 6 extends (refer to Fig. 2-5) from an eccentric position at the upper part 40 of the winch L into the rope drum 2, and drives a transmission, which is included in the lower part 41 of the rope drum.
- the transmission drives a rotation of the drum 38 either in a clockwise hauling-in direction 42 of the rope 43 at a high speed, small force and low torque or in a counter-clockwise one at a low speed, great force and high torque or allows a counter-clockwise sheeting out in the direction 44 of the rope 43 in the case also the sheeting-out button 5, 35 is actuated simultaneously.
