ところにある。However, in the prior art described above, as shown in FIG. 4, lubrication of the slip portion 3 between the gear core 1 and the gear 2 pressed into the gear core 1 is hindered by the pinion C of the gear core 1. , The direction of the lubricator 8 is limited. For this reason, there has been a problem that lubrication is performed using a dedicated device in a separate process even in the assembly process. Therefore, the present invention solves such a problem. The purpose of the present invention is to apply oil to a base part of a watch body, assemble a gear core having a slip portion, and rotate the slip portion to thereby reduce the slip portion. The place to secure oil.

することを特徴とする。The method for lubricating a timepiece gear slip portion according to the present invention is characterized in that, when assembling a timepiece having a timepiece gear having a slip portion between a gear core and a gear portion, and a base component supporting the timepiece gear, Lubricating on the surface of the component near the slip portion and facing the gear portion, and then incorporating the clock gear on the base component and rotating the clock gear on the surface portion. The oil is drawn into the slip portion and secured.
ここで、前記ベース部品における前記表面部から前記
スリップ部に向かって低下した段差部分が形成されてい
ることが好ましい。Here, it is preferable that a stepped portion which is reduced from the surface portion toward the slip portion in the base component is formed.
本発明の上記の構成によれば、歯車スリップ部へ直接
注油をしなくても、ベース部品へ油を施し歯車芯を組込
み回転させることにより、歯車スリップ部の油を確保す
ることができるのである。According to the above configuration of the present invention, the oil in the gear slip portion can be secured by applying the oil to the base component and incorporating and rotating the gear core without directly lubricating the gear slip portion. .

適である。FIG. 1 is a plan view and a sectional view in which oil 6 has been applied to a base component 4 in an embodiment of the present invention. The base component 4 is assembled on the main plate 5 in advance. FIG. 2 is a sectional view incorporating a timepiece gear core having a slip portion, and FIG. 3 is an enlarged sectional view of the slip portion. 2 and 3, the oil 6 applied to the base component 4 incorporates the gear core 1 and the upper part of the gear core 1 is rotated by a jig 7 so that the gear core 1 and the gear Oil 6 to slip part 3 with 2
To draw in. At this time, the relationship between the clearance a between the base component 4 and the gear 2 and the clearance b between the base component 4 and the slip portion 3 is such that the relationship a ≦ b is such that the oil 6 can be easily drawn into the slip portion 3. . Also, the base part 4 shown in FIG.
Oil 6 is subjected to is good bead as possible, good relationship Z ≧ Z 1, further lubrication locations in relation to Z> a is optimal at least two places.
