Technical Data Reducers Miter and Bevel Gear Boxes Handling
This section contains general information regarding the handling of your reducer.
For details, refer to the manual supplied with your reducer
2. Mounting
2-1. Ambient conditions
Install the product in a well-ventilated, dry, dust-free location with an ambient temperature of -10 to 50°C.
Avoid use in locations having corrosive liquids or gases, or locations of possible fires or explosions.
If the gear box is to be used outdoors, furnish a cover or similar protection to avoid direct exposure to rain.
2-2. Transporting
Be sure to use the eye bolt on the top of the case or a suspension ring when transporting the reducer. Never hook wires or slings to the lateral/cross shafts.
Doing so may cause the shaft to lose its center position or other problems that can shorten the life of the gear box or cause it to fail.
Note) ED2/4/6 and ARA Gear Boxes do not come with eye bolts.
2-3. Mounting
Install the gear box by firmly fixing it on a solid, flat surface.
Ensure that the Miter Gear Box is in complete contact with the mounting surface, which will prevent shaking.
While ED2 & 4 and ARA Gear Boxes have no restrictions on the installation angle, the installation angle for ED6 through ED16 should be within ±5° and for ED20 and ED25 should be within ±2°.
To install an ARA Gear Box, use the three mounting holes at the center or the four mounting holes on the flange.
Recommended mounting bolt sizes
| ED | 2 | 4 | 6 | 7 | 8 | 10 | 12 | 16 | 20 | 25 |
|---|---|---|---|---|---|---|---|---|---|---|
| Bolt | M8 | M8 | M12 | M12 | M12 | M14 | M18 | M20 | M18 | M20 |
Note)
- 1. After installing the system, be sure to apply grease before actual operation. See the supplying grease in details.
- 2. ED2 & 4 can be installed in any direction. Avoid installing ED6 through ED25 in any direction other than the direction specified in the order.
(Contact us when changing the mounting, as the positions of the oil gauge and grease nipple change along with the mounting. ) - 3. ED12 and higher number models need a pressure vent. After completing the installation, be sure to replace the bleeder plug on the specified location with the supplied pressure vent.
2-4. Connecting
- ・When mounting a pulley, sprocket, or coupling on the lateral and/or cross shafts of a Miter Gear Box or ARA Gear Box, use due care to avoid bending the shaft or damaging bearings or oil seals.
- ・Align the shafts correctly. Shaft eccentricity as well as radial load exceeding allowable values can shorten gear, bearing, and shaft life and cause vibration or noise.
- ・When using a coupling, ensure correct attachment within the allowable alignment range recommended by the manufacturer.
We recommend our flexible couplings, which are available in a variety of types and suitable for many applications.
