Abstract
The utility model relates to a special bush for a piano peg which is a compound bush being pressure cast into molding with non-metal, high wear-resistant, and high friction coefficient material, comprising an external form with rein strings, a jacket wall with certain thickness, and an inner bore matched with the peg in an interference fit. The bush is embedded into the peg plate and sheathed on the rear part of the peg. The special bush for a piano peg is added with a bush on the peg plate, so that the peg does not directly contact with the peg plate, and the peg acts on the bush. The special bush for a piano peg makes use of high wear-resistant, high friction coefficient, strong weather resistance, and long service life of the bush to improve the constant frictional force and tightening force generated by the reversed torsion of the peg, therefore, improving service life. At the same time, the special bush for a piano peg can largely simplify preparing process and reduce manufacturing cost.
Description
Technical field
The utility model relates to piano manufacturing technology field, is specifically related to a kind of piano peg special axis cover, belongs to International Classification of Patents G10C3/00 " the mechanical hook-up parts of piano " field.
Background technology
In the prior art, for the tension force that guarantees that piano string is nearly 20 tons, the string shaft (wooden, multilayer glue laminated) that is used for fastening peg is in processing and manufacturing, and technological requirement is very strict, and cooperating between peg and the string shaft requires also very harsh during the later stage assembling.Because peg directly acts on string shaft, and the wearing quality of timber and friction factor are less, when long-term the use, very easily produce the loosening phenomenon of peg, influenced serviceable life.Simultaneously, because it is very complicated to change string shaft technology, it is very high to solve expense, is insoluble world subject in the piano production field.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of peg that makes to act on axle sleeve, improves friction and decides power and fastening force, thereby improve the piano peg special axis cover in serviceable life.
The purpose of this utility model is achieved through the following technical solutions.
A kind of piano peg special axis cover is a kind of composite shaft sleeve that adopts nonmetal, high abrasion, high coefficient of friction material die cast, constitutes by having the external form of reining in silk, certain thickness jacket wall and crossing the endoporus that win cooperates with peg.Described axle sleeve embeds in the string shaft, is placed in the rear portion of peg.
Compared with prior art, the utility model has added axle sleeve on string shaft, peg is not directly contacted with string shaft, and act on axle sleeve, utilize that axle sleeve high abrasion, great friction coefficient, weatherability are strong, the characteristic of long service life, improve the friction of peg reversed torsion and decide power and fastening force, thereby improve serviceable life.Simultaneously, simplified processing process reduces manufacturing cost greatly.
Description of drawings
Fig. 1 is the front view of the utility model piano peg special axis cover;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the synoptic diagram that axle sleeve embeds the string shaft position.
Among the figure: 1, axle sleeve, 2, rein in silk, 3, string shaft, 4, iron plate, 5, peg.
Embodiment
As shown in Figure 1, 2, piano peg special axis cover 1 is a kind of composite shaft sleeve that adopts nonmetal, high abrasion, high coefficient of friction material die cast, constitutes by having the external form of reining in silk 2, certain thickness jacket wall and crossing the endoporus that win cooperates with peg 5.
As shown in Figure 3, the position with string shafts 3 in the axle sleeve 1 embedding iron plate 4 of the present utility model because axle sleeve 1 has the external form of reining in silk 2, is able to closely fix with string shaft 3, then peg 5 is pressed into peg cover 1.
Claims (2)
1, a kind of piano peg special axis cover, piano specific complex axle sleeve for die cast, system selects for use nonmetal high abrasion high coefficient of friction material to make, and it is characterized in that: described axle sleeve has reins in an external form, has certain thickness jacket wall and crosses the endoporus that win cooperates with peg.
2, piano peg special axis cover according to claim 1 is characterized in that: described axle sleeve embeds in the string shaft, is placed in the rear portion of peg.
