4. Installation
Common
For the horizontal slow speed shaft level type (see P5), attach it as shown in the figure below.
Figure 4-1 Mounting Angle (Example: Foot mount type)
4-3 When Load Condition Is Critical
In cases of extreme vibration or frequent startup, it is recommended to knock the foot unit, and use a mounting bolt of at least class 8.8
(JIS B 1051) strength.
4-4 Flange Type Assembly Issues (Models: CNFM, CHFM, CNF, CHF, etc.)
[1] Remove the fan cover if there is one installed (reducer frame size of 6160 or more).
[2] Remove the nut and bolt for ring gear housing. Take care when loosening the nut, as the bolt for ring gear housing may rotate together.
[3] A nut of a different size to the nut for ring gear housing may be assembled between the nut for ring gear housing and casing when
the device is shipped. Remove this nut, as it is a spacer replacement nut for preventing damage to the faces of the nut for ring gear
housing and casing, as well as for preventing the nut coming free of the threaded section of bolt for ring gear housing.
[4] Assemble the device to the driven machine, and tighten the nut and bolt for ring gear housing with the tightening torque shown in Table 4.2.
-Disassembly prevention nuts are installed at 2 locations of the bolt for ring gear housing (opposing angles) to prevent disassembly
of the reducer in case the bolt for ring gear housing is removed. Do not remove the disassembly prevention nuts. Removing them
may result in the casing, ring gear housing, internal cover, motor and other parts disassembling and falling off, and may cause injury.
-Using only the disassembly prevention nuts with the nut for ring gear housing removed does not generate a sufficient level of
torque. Do not use only the disassembly prevention nuts for ring gear housing for long periods of time, move them excessively or
subject them to shock. Lubricant or grease may leak if there gaps develop between any of the mating faces.
-Tightening the nut for ring gear housing changes the axial force of the disassembly prevention nuts, and may result in them coming
loose. To remove the CYCLO Drive after temporarily assembling the device to the driven machine, check that the disassembly
prevention nuts have not become loose.

Note : 1. The symbol
□
in frame size can be "0" or "5."
2. If a nut and bolt are prepared by the customer, a tightening torque that suits the nut and bolt should be used.
3. The position of the disassembly prevention nuts and the shape of each part depend on the frame size.
