Shaft center of the connecting machine and the shaft center of the reducer must be aligned in a straight line.
Example of gear coupling
• The displacement amount of δ and θ should be minimized as small as possible.
•
(Reference: In case of chain coupling, δ should be within 2% of the roller chain pitch and θ should be within 1°)
(1) Shaft center of the connecting machine and the shaft center of the reducer must be set parallel to each other.
(2) Chain, V-belt tension and gear engagement must be at right angle to the shaft.
(3) V-belt tension : If it is too tight, the bearing may become damaged.
Chain tension : If it is too tight, the bearing may become damaged. High impact force may also occur
if it is too loose which would result in adverse effects on the reducer and application.
The tension of the chain should be correctly adjusted.
4-1. When directly connected
4-2. Attaching Chains, V-belts, Gears, etc.
The δ and θ differ according to the type of coupling. Therefore, they should be within the allowable value defined by the manufacturer.

Correct
Application
Sprocket
Application
The chain is too loose.
T
he tension of V-belt and chain are properly set,
also pulley and sprocket are properly positioned.
The sprocket is positioned in the
reverse direction so that the load
point moves to the shaft edge.
