点Ｐ位置に合わせることが困難で、正確な取付けのため
に時間と熟練を要している。For installation, use a gap gauge 1 as shown in Figure 2. However, since the front face 5 of the magnetic sensor head 4 is normally flat with respect to the outer diameter circle 3 of 1=72, it is not possible to align the center C of the magnetic sensor head 4 with the contact point P between the gap gauge 1 and the outer diameter circle 3. Difficult and requires time and skill for accurate installation.
また、磁気センサヘッドの正面は開放されたままなので
、取付けに際して該ヘッドを取付は用ビスなどと一緒に
扱うと、該ヘッドを損傷することがあった。Furthermore, since the front side of the magnetic sensor head remains open, if the head is handled together with mounting screws during installation, the head may be damaged.

べきギｔ７ツブと等しくしている。As shown in FIG. 3, the gap setting portion 7 has an outer surface formed into an arcuate surface that corresponds to a part of the outer diameter circle 3 of the gear 2, and an inner surface formed into a flat surface. Minimize the distance (CP) between the center position C and the outer diameter circle 3,
This interval is made equal to the pitch t7 that the magnetic sensor head 4 should take with respect to the gear 2.

キャップ６を除去する。For example, as shown in FIG. 4, the magnetic sensor head 4 and the gear 2 have the gear 2 attached to the end of the rotor shaft 10 of the motor 9, and the magnetic sensor head 4 fixed to the machine frame portion 11 of the motor. At that time, the gap setting cap 6 is left attached and the outer surface of the cap 6 is brought into contact with the outer diameter of the already fixed gear 2 as shown in FIG. and then remove the cap 6.

ッド４が固定された後であるから、前記の設定されたギ
ャップに狂いが生じるということは無い。When the magnetic sensor head 4 is brought into contact with the gap setting cap 6 along the outer diameter of the gear 2, since the outer surface of the cap 6 is an arc that corresponds to a part of the outer diameter circle 3, it stably contacts the gear 2. In addition, the gap that the magnetic sensor head 4 takes with respect to the gear 2 at the center zero point is always achieved as the distance CP, and no special technology is required. Further, since the gap setting cap 6 is removed after the magnetic sensor head 4 is fixed, there is no possibility that the set gap will be distorted.

要がある。As shown in FIG. 1, the shape of the gap setting cap 6 is such that the gap setting portion 7 is narrower than the diameter of the front face 5 that is attached to the magnetic sensor head 4, and also covers the front face. Also, the leg portion 8 may be attached to the magnetic sensor head 4.
Any type of material that engages with the side surface is sufficient. However, it is necessary that the magnetic sensor head 4 be easily attached and removed later.
