Comfortable to ride in thanks to the Gear Couplings

The Kyushu Hasec’s gear couplings are used on the first domestic ultra-low-floor trams.

Important role to transfer motive energy to the wheels

The drive shaft which connects the motor running by large power to the wheels and the shaft coupling fulfills a role to connect the shaft.

 
The Kyushu Hasec’s gear couplings are highly reliable couplings which can transmit large shaft power through the gear structured transmission system as applied to industrial machines such as iron-and- steel-making facilities.

 
And the gear couplings fulfill a role to drive the trams.

Large allowable misalignment that puts comfortable ride in to practice.

The street cars do not always run in smooth and straight load but also in rough and curved load.

 
Parallel, angle and axial direction.

 
Should run responding to various changes of the load conditions. If not, a comfortable ride cannot be realized because of excessive vibration even in low speed.

 
The Kyushu Hasec’s gear couplings have large admissible misalignment such as parallel, angular, composite, axial misalignment, thus smooth operation can be actualized.
