FSMML40

FSMML40

Flexible coupling - slotted type - anti-locking type - long type.

Zero backlash.

Elasticity compensates for radial, angular and axial deviations.

High torsional stiffness and sensitivity.

The clockwise and counterclockwise rotation characteristics are exactly the same.

Maintenance-free, oil-resistant and corrosion-resistant.

Since eccentricity, angular deviation, and axial displacement are all individual allowable values, the allowable value will decrease when several causes of axial eccentricity occur simultaneously.

Product Overview

Model Description 

 

Coupling fixing method

(1) There are five ways to fix the shaft.
(2) Fastening bolts or countersunk head bolts should be properly tightened using a hex wrench or torque wrench.








Coupling installation diagram

♦ To ensure proper installation of all types of couplings, prevent contact between the two shafts, and maintain normal operation, it is recommended to assemble them according to the following diagram.






Coupling Selection Guide

♦ Induction motor

(1) It has more than 3 times the torque during instantaneous rotation.

(2) The motor spindle will have a reciprocating motion of ±1.5mm during operation. It is not recommended to use the slotted type.

(3) If a DC motor is used, it can be used in a dusty working environment.

 

♦ Stepper motor

(1) There is no 3 times the torque during instantaneous rotation, but it is the maximum rated torque of the motor.

(2) The torque at low speeds is greater than that of servo motors of the same class.

(3) The higher the motor speed, the lower the torque.

(4) The motor will heat up during continuous operation (this can be mitigated by using a spring-loaded type).

* Stepper motors have lower output power than servo motors.

 

♦ Servo motor

(1) It has more than 3 times the torque during instantaneous rotation.

(2) Within the rated speed range, the torque is the rated torque.

(3) The torque is the same at low speed and high speed.

(4) The motor temperature rise is very small during continuous operation.

 

♦ Encoder

(1) Built into the servo motor, with extremely low driving torque

(2) Or connected to a stepper motor (optional)
