PURPOSE:To connect a rotary detector as a later-mounting type by engaging the shaft of a rotary machine body to that of the rotary detector with a protrusion and a recessed part where the shaft center is shifted and fixing the rotary detector body to the rotary machine body with screws. CONSTITUTION:The inner ring of an encoder bearing 20h is press-fitted to an encoder shaft 20a and an outer ring is housed in the bearing box of an encoder base 20g and then is fixed by a bearing retainer 20i. The encoder shaft 20a protrudes toward the side of a shaft 1 of an electric motor and is connected to the shaft 1 at this part. A hole which is larger than the encoder shaft 20a is formed at the shaft center part of an encoder cover 20e and an end cap 20j is press-fitted, thus clamping and fixing a rotary encoder 20 which is a single-substance product with one function to an end bracket 6 of the electric motor with a screw 20k. |
