Sumitomo PARAMAX 9000 Series - Coupling with Other Machines; Coupling Installation Guide

5-1) Installation of coupling
•
When attaching a coupling, be careful not to apply impact force or excessive thrust to the
shaft; otherwise, the bearing may be damaged.
• Shrink fit or shaft-end thread is recommended for mounting (Fig.11).
(1) Use of coupling
The dimensions (A,B and X) illustrated in Fig.12 shall be within the tolerance shown in
Table 11.
COMMON
5. Coupling with other machines
•
When coupling PARAMAX DRIVE to a load, confirm that the alignment is within the specified limits shown in the
maintenance manual, drawings, catalog, etc; damage to the system may occur, due to misalignment.
When a belt is used for coupling the unit with another machine, check that the belt tension and the parallelism
of the pulley are within the specified limits. When the unit is directly coupled with another machine, check
that the direct coupling accuracy is within the specified limits; the system may be damaged, due to
misalignment.
Correctly tighten respective bolts to the specified torque shown in the drawing, catalog to prevent damage to
the system due to loose components.
Install appropriate guard devices around rotating parts; or injury may occur.

•
•
Remove the key temporarily attached to the output shaft of PARAMAX DRIVE when the shaft is free-rotating
(i.e. not loaded); otherwise, injury may occur.
•
Confirm the direction of rotation before coupling PARAMAX DRIVE with its driven machine.
Difference in the direction of rotation may cause injury or damage to the system.

(2) Use of chain, sprocket and gear
• The chain tension angle shall be perpendicular to the shaft of PARAMAX DRIVE.
• The pitch circle of the sprocket and gear shall be more than three times of the shaft diameter.
• Locate the sprocket and gear as close to PARAMAX DRIVE as possible so that the point of application of the load
will be closer to the PARAMAX DRIVE'S vertical centerline (Fig.13).
(3) Use of V belt
• Excessive V belt tension will damage the output shaft and bearing. The amount must be specified by V belt
manufacturer.
• Eccentricity of parallelism between two pulleys shall be less than 20' (Fig.14).
• Use a matched set with identical circumferential length when more than one V belt is used.
