How to use this operating manual Before working with this gearbox (assembly, operation, maintenance, inspection, etc.), please read this operating manual carefully to obtain an overview of the correct way of handling the Fine Cyclo precision gearbox, the applicable safety regulations, and the warnings to be noted. Keep this operation manual where you can access it at any time, as required. Target group This operating manual is intended for trained technical staff familiar with the transport, assembly, lubrication, operation, maintenance and inspection of the gearbox. Text markers This operating...

Additional notes Pictogram Meaning Further information Information about disposal Information about explosion protection Basic safety instructions Transport, assembly, lubrication, operation, maintenance and inspection may only be carried out by trained technical staff, otherwise there is a risk of injury or damage to the gearbox/machine. The gearbox may only be used for its intended purpose, otherwise there is a risk of injury or damage to the gearbox/machine. Designated use Fine Cyclo precision gearboxes are motor-driven gearboxes for industrial and commercial systems. The permitted speeds...

Transport The delivery must be checked for possible damage incurred during transport as soon as it arrives. If any is found, the transport company must be advised immediately. If it must be presumed that the transport damage would restrict proper operation, commissioning may not be carried out. Installation of transmission elements Gearboxes with a hollow input shaft need to have MoS2 paste or spray (e.g. Molykote) applied to the motor shaft/counterpart before the counterpart is fitted. Caution! Clamp connections may not be treated with MoS2 paste or spray (e.g. Molykote). Clamp connections must...

Preparatory tasks Material damage! Improper cleaning! The corrosion protection should never be mechanically removed (e.g. with an abrasive).  Only alkaline cleaning agents may be used for cleaning. Care should be taken to ensure that the seals do not come into contact with the cleaning agent. When handling lubricants and anti-corrosion agents, the personal and environmental safety regulations are to be observed in accordance with the corresponding safety regulations and DIN 52900 safety data sheets.  The anti-corrosion agent (brand Valvoline Tectyl 846/K19) used on the shaft ends or hollow...

The specified torque values allow for a tightening factor of 1.4 and a friction factor of 0.15. The values must be recalculated if the conditions differ. In case of doubt, contact Sumitomo Drive Technologies. The contact surfaces of the slow-speed shaft flange and housing must be clean and dry. The gearbox connections and torques can be safety transmitted under these conditions. The equivalent stress, i.e. the degree to which the yield strength stress is used during tightening, amounts to 0.9. "Yield point controlled tightening" as per VDI 2230 increases the transmittable torque of bolts by approximately...

For gearboxes which are sealed by means of locking caps on the output (e.g. D series), axial securing of these caps by the customer connection design is recommended. For implementation questions (e.g. tolerances), please contact Sumitomo Drive Technologies. The creation of a maintenance plan is strongly recommended. It is the customer's responsibility to evaluate critical control limits according to the environmental conditions of their application. Therefore, the following recommendations are only of limited use and may need to be amended or extended:  Check oil seals for leaks.  The seals...

Motor mounting via clamp ring connection In principle, the connection between motor shaft and gearbox input shaft is possible for all gearbox types described in this manual. Please refer to 4.10 Installation instructions for clamp ring connections regarding the correct mounting between motor and gearbox. The assembly procedure described there is valid for all other gearbox types described in these instructions. With regard to the required bolt tightening torques for the clamp connections and the transmittable torques, the specific dimensional drawings assigned to the respective product must be...

Tab. 2 Bolt tightening torque and permissible drive torque values for input shafts with clamping ring F4CF-D (clamp ring design) Tab. 3 Bolt tightening torque and permissible drive torque values for input shafts with clamp ring F4CF-D (clamp ring design) Note: reduced transmittable torques with bushing, different from standard The specifications of the transmittable input torque of the clamp ring connection are only valid for gearboxes of the D, DA, and UA series (clamp ring design) according to catalogue design and must not be exceeded. For all other clamp designs, the bolt tightening torques...

Installation instructions for clamp ring connections Remove cover and bring input shaft into position with clamp ring and bushing The alignment of the central axis of the motor (motor shaft) and the gearbox drive shaft (gearbox axis) must match (see the assembly tolerance chapter of the corresponding series). For the clamp ring design, the required tightening torques and the transmittable torques under Tab. 1 to 3 or according to the specifications of the dimensional drawing assigned to the specific product must be taken into account. The motor is installed in the sequence 1-7 as described below....
