technical data Reducer DCBL Hypoid Motor Handling
This section describes general handling of DCBL Hypoid Motor drivers.
For details, please refer to Instruction Manuals attached to the product.
Installation
1. Installation direction
- - There are no restrictions on the installation direction. It can be installed in any direction, horizontally, vertically or at an angle.
Installation
1. Face mount type
- - When installing on the machine body, please use the taps on the case.
- - When connecting with a coupling, be sure to center the shaft properly. Eccentricity of the shaft will shorten the life of the bearings, gears, and shaft, and will also cause noise and vibration.
- - Center the chain or belt accurately and adjust the tension so that the load on the output shaft does not exceed the specified value.
- - When connecting, please be careful not to hit the output shaft, coupling, pulley, or sprocket too hard, as this may damage the output shaft bearing.
2. Hollow shaft type
2-1. Mounting to the driven shaft
- ・The hollow shaft inner diameter tolerance is manufactured to JIS H8. The driven shaft should normally be finished to h7, but in cases of large impacts or radial loads, use a slightly tighter fit of around js6 or k6.
- - When installing onto the driven shaft, apply molybdenum disulfide grease to the surface of the driven shaft and the inner diameter of the hollow output shaft before inserting.
- - If you make and use a jig like the one shown on the right, you can insert it smoothly.
2-2. Fixing to the driven shaft
A. When there is a step on the driven shaft
Fabricate an end plate as shown in the diagram below and secure the hollow output shaft and driven shaft in place.
B. Example when there is no step on the driven shaft
There are two fixing methods:
2-3. Torque arm rotation stopper
Attach the torque arm to the driven machine side of DCBL Hypoid Motor using a hexagon socket head bolt.
At the torque arm's anti-rotation section, allow some freedom of movement between DCBL Hypoid Motor and the driven shaft, and never fix the torque arm with an anti-rotation bolt.
A lack of freedom can cause damage to the bearings inside the reducer.If the start-up frequency is high or if there is repeated forward and reverse operation, installing a rubber bushing between the torque arm and the anti-rotation bolt (or spacer) will reduce the impact.
2-4. Removal from the driven shaft
- - Remove the driven shaft from the hollow output shaft so that no excess force is applied between the casing and the hollow output shaft.
- - If you make and use a jig like the one shown on the right, removal will be smooth.
