In the actual field application of encoders , we will encounter various problems during installation, including mechanical and electrical ones. If we are not careful or do not do it in a standardized manner, it will affect the normal use and lifespan of the encoder.
solid shaft encoder
Solid shaft encoders can be installed in two ways: with a synchronous flange and with a clamping flange. The mounting brackets will also differ.
1. You can fix the encoder to the mounting bracket by directly using the mounting holes on the encoder flange end face.
2. The encoder is fixed to the mounting bracket by using the mounting boss of the clamping flange and the clamp (2 in the figure).
3. The encoder is fixed to the mounting bracket by using the clamping groove of the synchronous flange and the eccentric clamp (2 in the figure).
Blind Hole Hollow Shaft Encoder
Regardless of whether it is an incremental or absolute encoder, it is necessary to pay attention to whether the length of the shaft and the depth of the bushing are compatible. For example, for DBS60, the shaft length is generally required to be no less than 15mm and no more than 40mm.
For ATM60_SSI, the shaft length is generally required to be no less than 15mm and no more than 30mm.
Through-hole hollow shaft encoder
Incremental encoders can be configured to have the clamping ring and mounting spring on the same side or on different sides, depending on the installation environment. The main consideration is whether it is more convenient to fix the clamping ring after the mounting spring is in place.
Coupling
1. When installing the coupling, it should be kept in its natural, original state and should not be twisted in any way;
2. The torque of the set screw on the coupling is generally 0.6 Nm. Do not use excessive torque, which may damage the screw.
3. The encoder and coupling must be installed concentrically; any deviation may cause the mechanical load on the encoder shaft to exceed the rated range.
Mechanical zeroing
Incremental encoders can be zeroed by markings on the shaft or bushing and flange, which facilitates the assembly and use of the encoder in the field.
The zero-point mark on the flange face corresponding to the bushing fixing hole on the through-hole/blind-hole hollow shaft encoder is the mechanical zero position.
The mechanical zero position is the flat end of the solid shaft encoder whose center line is aligned with the zero mark on the flange.
