- Mount as outlined here.
Step
Mounting procedures
1
Install the key on the driven shaft.
Note) Use a bar key. Do not use a tapered or gib headed key. Doing so ay ake the output shaft eccentric or cause other proble s which will shorten the life of
the reducer or cause it to fail.
2
Hoist the reducer using the eye-nut on the top of the housing and slowly insert it onto the driven shaft.
Align the phase of the key before inserting it.
Note) If the shaft fits too tightly, help the hollow output shaft slide s oothly by lightly tapping the end with a plastic ha er. (Apply grease or olybdenu
disulfide to the driven shaft.)
Be careful not to da age the oil seal.
3
Use an end plate to fix the reducer and driven shaft in the thrust direction. The end plate can be fixed on the driven shaft with a stop ring in
the stop ring groove of the hollow output shaft, or by fixing it to the end of the shaft, but taking disasse bly into consideration, we
reco end the ethod securing the stop ring and end plate.
Place a stop ring in the stop ring groove on the hollow output shaft and ount the end plate on the reducer output shaft side of the stop
ring. Then fix the end plate to the driven shaft with hex bolts.

●
If the driven shaft is vertical and points down
Use the stop ring and bolts as shown in the figure above to prevent the reducer fro falling off, and take all safety precautions necessary.
Note) Always apply Loctite or si ilar locking agent to the bolts.
●
If the driven shaft faces up
Machine a shoulder on the driven shaft to prevent ove ent in the thrust direction.
(2) Securing
(Torque ar )
- Secure as outlined here.
Step Mounting procedures
1
Mount the torque ar to the reducer. Select the proper ounting bolts by referring to the reco ended installation bolts for
the S type.
Note) The torque ar is subject to reaction force fro the reducer. Use a torque ar robust enough by considering the bending o ent under
axi u torque, such as when starting and stopping.
2
Mount the reducer on the driven shaft, then ount the torque ar to the fra e of the achine. When ounting the torque
ar to the achine fra e, leave clearance between the reducer and driven shaft to avoid causing eccentric loads.
Note) If the torque ar is fixed to the achine fra e, the reducer output shaft bearings and the driven shaft could break due to excessive radial
and thrust loads, so always provide the torque ar a degree of freedo .
Note) To reduce shock, use rubber bushings between the torque ar and ounting bolts on the achine fra e side.
(Tie rod)
・ Please consult with Tsubaki E&M.
(Flange and base mounting notes)
・ Install on a s ooth flat installation surface that can easily withstand the weight of the equip ent.
・ Select ounting bolts reco ended for the solid output shaft type reducer.
・ Mount as outlined here.
Step
Mounting procedures
1
Free the driven shaft in the thrust direction.
2
Insert the reducer into the driven shaft, then ount to the flange surface and base surface.
3
Fix the reducer in the thrust direction of the driven shaft.
4
Fix the driven shaft in the thrust direction.
Note) If the reducer is ounted on its flange surface and base surface after it is fixed to the driven shaft in the thrust direction, the bearings on the reducer or the driven shaft
will be subject to thrust force which could result in reduced life or achine failure.
(5) Connection (input shaft of the HDR Series, solid output shaft type)
CAUTION
Connecting the motor and driven machine (input shaft of the HDR Series, solid output shaft type)
・ When connecting the HDR/HDM Series to a otor and the driven achine, pay careful attention to centering, belt tension, and the parallelis of
the pulleys. When directly connected, pay careful attention to the accuracy of the direct connection. When belt driven, correctly adjust the belt
tension. Before operation, ensure that the tie bolts for the pulleys and couplings have been fully tightened. Otherwise there is a risk of injury due to
flying debris and da age to equip ent.
・ Install a cover so that rotating co ponents will not be touched. Otherwise there is a risk of injury.
・ When the HDR/HDM Series will rotate independently, re ove the key that is te porarily installed to the output shaft. Otherwise there is a risk of
injury.
