Definitions
- the present invention relates to a combined manual and motor adjusting drive for adjusting the string tension of a stringed instrument, in particular a guitar according to the features of the preamble of claim 1.
- Such adjusting drives are known in principle, they gain particular importance in connection with stringed instruments that are equipped with automatic tuning devices.
- a mood of the musical instrument is executed fully automatically and under the control of a calculation and comparison unit, by such a unit evaluating signals and data recorded by a detector unit and corresponding to an actual actual mood, comparing these with a target mood and corresponding ones Correction and control commands to the drive motor of the adjustment are.
- the adjusting device is then adjusted by means of the drive motor by motor until the desired tuning of the string is achieved in the desired accuracy.
- Adjusting drives are designed as a hybrid, in addition to the drive motor and a manually operated actuator, such as a thumbscrew, a lug for a tuning tool or the like., By means of which the vortex on which the tuned string runs, rotated and so the string tension and their mood can be changed.
- the adjusting drive according to the invention is characterized in that the force transmission member, with which the force is transmitted from the output shaft of the motor to the vortex, is an at least three-stage reduction gear, wherein the first stage is the one which engages the drive motor with its output shaft, the last stage that which transmits the force to the vortex for twisting it. Furthermore, the adjusting drive according to the invention is characterized in that the adjusting element for manual adjustment of the drive acts on a lying between the first and the last stage stage of the reduction gear to force application.
- the choice of a multi-stage, at least three-stage gearbox allows for a relatively high to be transmitted forces required for tensioning and holding the strings in the required for the desired mood tension, the individual transmission elements comparatively filigree.
- the multi-stage gives the possibility to pack the individual gear stages very compact to each other and so to realize a very small in its design dimensioned gearbox and thus a particularly small sized adjustment.
- the entire gear train be designed from all stages for a required self-locking, whereas in an actuation of the actuating element, the frictional forces to be overcome in the gear both in the direction of the vortex and backward in the direction of the uncoupled freely rotating drive motor are low, so that the actuator without a significant additional resistance can be manually operated and moved.
- the reduction gear is at least four stages, in particular seven stages. More than three, in particular four and also up to seven gear stages allow here even more flexible and in the individual parts smaller dimensioned distribution and arrangement of the entire transmission with the corresponding advantages in terms of a compact space.
- a spur gear has proven to be particularly advantageous.
- the reduction gear is designed with advantage as stated in claim 4.
- a vote on the drive motor taking into account the maximum force applied by the engine and the usual force exerted by a string held in tune to the last gear stage or which is required for pulling and holding the string in the correct pitch and must be applied.
- values between 3,000: 1 and 4,000: 1, in particular between 3,500: 1 and 4,000: 1, more preferably between 3,770: 1 and 3,780: 1, have proven to be suitable.
- a suitable reduction of the transmission step (s) between the force introduction of the actuating element and the vortex is advantageously in the range between 30: 1 and 50: 1, in particular between 35: 1 and 45: 1.
- a stepping motor has proven to be advantageous as a drive motor. This can be driven due to the very precise vorgebaren angle positions without measuring the frequency of the string in a target window, so that then the window of the frequency and the travel are not so large, the mood can be set faster.
- one aspect of the invention is also a device for automatically tuning a string of a stringed instrument, which usually comprises a detection means for detecting the current tuning of the string, a calculating and comparing unit for comparing the current tuning with a desired tuning and for generating Having actuating signals and containing an adjusting drive as described above, the drive motor can change the string tension depending on the control signals.
- a further aspect of the invention resides in a stringed instrument, in particular a guitar, which contains an adjusting drive or an automatic tuning device as described above.
- FIG. 1 an embodiment of an adjusting drive 1 according to the invention is shown, which is to operate both manually and by motor.
- the adjusting drive is arranged with its essential components in a housing which is formed by a lower housing part 2 and a housing lower part 2 can be placed, the housing lower part 2 substantially closing housing cover 3.
- a guide sleeve 4 is formed, in which a vortex 5 is guided radially.
- the vortex 5 has a Aufwickelab Beatles 6, on which a string of the stringed instrument, here a guitar, in particular an electric guitar, runs up with a free end.
- the vortex 5 is rotated in a conventional manner to wind the string end on the take-up 6 or unwind from this, to vary the string tension and thus their mood.
- the string end is fixed to the vertebra 5 by means of a combination of a clamping pin 7 and a clamping screw 8.
- the clamping pin 7 is of the in the FIG. 1 Above darg Congressen end side inserted into the vortex 5, the clamping screw 8 has an internal thread, which with a on the in the FIG. 1
- the front end shown above corresponds to the outer side of the vortex 5 arranged on the outer side and can attack there for screwing the clamping screw 8.
- a transverse bore is arranged in a manner not shown, through which the free end of the string can be introduced.
- the adjustment drive 1 has a motorized adjustment of the rotational position of the vortex 5 via a drive motor 9, which is an electric motor, in this embodiment, a stepper motor.
- a gear 10 On the output shaft of the drive motor 9, a gear 10 is mounted with a circumferential toothing.
- This gear meshes with its peripheral teeth with a gear 11 of larger diameter, which forms the first gear stage of a multi-stage reduction gear and is arranged freely rotatable on a first axis.
- a gear 12 of smaller diameter is firmly connected, which meshes with a freely rotatable on a second axis arranged gear 13 with a larger diameter. This forms a second gear stage of the reduction gear.
- the gear 13 is fixedly connected to a gear 14 of larger diameter arranged above it on the same second axis, which in turn is connected to a gearwheel 15 which is freely rotatable on a third axis larger diameter meshes, which forms the third gear stage of the reduction gear.
- a gear 16 With the gear 1 5 is fixedly connected to a gear 16 arranged above it with a smaller diameter.
- Fixedly connected to the gear 17 is a further gear 18 with a smaller diameter. This meshes with a freely rotatable on the third axis above the gear 16 arranged gear 19 of larger diameter, which forms the fifth gear stage.
- gear 1 9 Fixedly connected to the gear 1 9 is another gear 20 of smaller diameter. This meshes with a last gear 21 of larger diameter on the second axis above the gear 18 and freely and independently of the latter rotatable about the second axis. This gear forms the sixth gear stage. With this gear 21 is fixedly connected to a same on the same second axis arranged gear 22 which transmits the force in a seventh and final gear stage on a fixedly connected to the vortex gear 23 and drives the vortex so to rotate.
- the drive force applied by the drive motor 9 is transmitted to the swirl 5 via a multistage (total seven-stage) reduction gear, this reduction gear being a spur gear.
- the overall reduction ratio is about 3775: 1 and is chosen so that it forms a self-locking for the region of the force applied by the auflaufelabites 6 of the vortex 5 accumulating string or the torque associated therewith. This is necessary because the drive motor 9 is a freewheeling in the de-energized state drive motor, this must also be for the additional drive option of the adjustment drive 1 via a manual drive.
- gears 10, 11, 12, 13, 14 and 23 are preferably formed of brass or bronze. On the one hand, these materials are sufficiently stable, on the other hand, they allow a proper shrinkage and "self-lubrication" of these gears.
- the other gears 15, 16, 17, 18, 19, 20, 21 and 22 are preferably made of steel by means of so-called metal injection molding (MIM). This method allows a comparatively inexpensive production of durable and dimensionally accurate gears with small dimensions.
- MIM metal injection molding
- a manual drive shaft 24 is provided, on which a fixed wing 25 is fixed.
- the wing 25 serves as a handle for rotating and adjusting the hand drive shaft 24.
- a crown wheel 26 is arranged at the end remote from the wing end of the hand drive shaft 24, arranged.
- the manual drive shaft 24 protrudes through an opening 27 in the lower housing part 2 in the latter, wherein the crown wheel 26 is positioned within the housing base 2 and meshes with the gear 17 of the fourth gear stage.
- the hand drive shaft 24 engages the fourth stage of the reduction gear, by operating the blade 25, the manual drive shaft 24 can be rotated and thus a rotation of the vortex 5 for manual adjustment of the string tension can be achieved.
- This is possible because the attack of the crown wheel 26 of the manual drive shaft 24 takes place at a point in the reduction gear on which neither gear down in the direction of the vortex, still gear upwards in the direction of the drive motor so high clamping or friction forces are present that a manual operation would not be possible. Rather, the forces present in the transmission can be easily overcome and the vortex can be twisted.
- the reduction of the manual drive shaft 24 (starting from the crown gear 26 on the fourth gear stage to the vortex 5) is about 40: 1, to the motor shaft, starting from the manual drive shaft 24, a translation of about 1: 1 90 given.
