Abstract
This invention is concerning easily installing an encoder main unit to a disk unit disposed on a shaft, without contacting a light-receiving element and an LED. An encoder installing structure and method using a spigot unit according to this invention are a configuration and method including: a shaft end which is a spigot inserting portion of a motor shaft of a motor; a disk unit which is fitted in an outer periphery of the shaft end so as to be fitted as a first spigot fitting portion and includes a disk; a screw hole which is formed at a shaft center of the shaft end along a shaft direction of the motor shaft.
Claims4
An encoder installing structure using a spigot unit, comprising:
- a shaft end (51) which is a spigot inserting portion (50) of a motor shaft (6) of a motor (5);
- a disk unit (11) which is fitted in an outer periphery (51a) of the shaft end (51) as a first spigot fitting portion (41) and includes a disk (2);
- a screw hole (11A) which is formed at a shaft center of the shaft end (51) along a shaft direction (P) of the motor shaft (6);
- a fixing screw (30) which is disposed in the disk unit (11) and is screwed into the screw hole (11A);
- and
- an encoder main unit (12) which is disposed in the disk unit (11) and includes a light-receiving element (14) and an LED (13) disposed sandwiching the disk (2), wherein
- the encoder main unit (12) is inserted into the disk (2) from the side (P1) which is a direction intersecting orthogonally with the shaft direction (P).
