CN201185079Y - Guitar chord axis driven by circular arc tooth worm gear and worm screw structure - Google Patents

Abstract

The utility model relates to a guitar tuning pate that can improve the self-locking of the chord line and is driven by an arc gear worm structure. In the driving structure of the tuning page, the scale cylinder generatrix of the worm gear is of an arc shape, so that overlapping surface between the surface of the gear and the worm screw is enlarged, thereby locking the chord line, and the chord line is uneasy to be loosened, and is easy to be positioned and the sound is correct.

Description

The guitar peg of circle-arc tooth worm and gear structure transmission

Technical field

The utility model relates to a kind of drive mechanism device of guitar peg, especially can make guitar string of a musical instrument locking positioning, keeps the guitar peg of accuracy in pitch.

Background technology

The drive structure of gear worm of present known guitar peg is by angular gear and worm geared, so just a bit meshing contact between the peg transmission of structure transmission is staggered, so transmission is not steady, and worm screw and gear teeth backlash are bigger, cause the string of a musical instrument not have self-locking performance easily, return pine and the inaccurate situation of accuracy in pitch.

Summary of the invention

For the guitar peg string of a musical instrument that overcomes existing angular gear and worm structure transmission returns pine and the inaccurate deficiency of accuracy in pitch, the utility model provides a kind of circle-arc tooth worm gear guitar peg, not only can lock the string of a musical instrument but also location institute tuning standard.

The technical scheme that its technical matters that solves the utility model adopts is: the utilization space meshing principle, change the bus of angular gear reference cylinder into circular arc, tighten in the string of a musical instrument process at rotary worm, the face that overlaps when cylindrical worm meshes with worm gear strengthens, changed was the engagement situation of any meshing contact in the past, reached the purpose of the locking string of a musical instrument and accuracy in pitch location.

The beneficial effects of the utility model are: worm and wheel tooth engaging conformation compactness, registration is big, stable drive, improves the self-locking performance of the guitar string of a musical instrument.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further specified.

Fig. 1 is the schematic diagram of circle-arc tooth worm and gear transmission.

Fig. 2 is the sectional view of circle-arc tooth worm and gear transmission.

Among the figure (1). cylindrical worm, (2). circle-arc tooth worm gear, (3). circle-arc tooth reference circle of wormwheel cylinder circular arc bus, (4). wrom tooth (5). the cylindrical worm flank of tooth.

Embodiment

In the embodiment shown in fig. 1, cylindrical worm (1) promotes circle-arc tooth worm gear (2) transmission in the mode of helical rotation, and wrom tooth (4) strengthens and stressed its stable drive that evenly makes with worm screw (1) field of conjugate action, when worm screw stops operating, but the locking string of a musical instrument.

As shown in Figure 2, the flank of tooth of the worm gear of circle-arc tooth reference circle of wormwheel cylinder circular arc bus (3) and the cylindrical worm flank of tooth (5) interlock mutually simultaneously, the backlash reduces, and compact conformation reaches the locking string of a musical instrument, improves the purpose that the string of a musical instrument returns pine.

Claims (1)

1. The guitar peg of a kind of arc teeth worm structure transmission, wormgear engaging worm is characterized in that: in the drive structure of gear worm of peg, the bus of reference circle of wormwheel cylinder is a circular arc.
