[Note] Type of motor, for which the belt can be applied, is till EDM4321V. EDM4331V and
EDM54, EDM68 are for direct connection only.
Belt speed should be : -
Standard V belt (A, B, C, D types) ..... 30m/sec or
less
Narrow V belt (3V, 5V, 8V types) ....... 40m/sec or
less
This matter should be taken into consideration when
pulley diameter is determined. The belt tension differs
depending on the kind of belt however, the radial load
imposed on the motor shaft should be less than the values in the above table.
(4) Mounting of coupling and belt pulley
Coupling and belt pulley should be mounted carefully not to damage the motor bearing.
Lightly press-fit them by wooden or plastic hammer. In case of heating, heat them until about
100°C uniformly. In case of press-fitting, remove the rust preventive agent on the shaft end by
petroleum solvent or alkali solvent, and apply molybdenum disulfide.
[Caution]
In case that the pulse oscillator for speed detection is provided on the shaft end of non-
transmission side, be careful not to give impact to it when coupling and belt pulley are
inserted since it may be damaged by such impact. (See Structural Drawings Fig.17
～
Fig.20)
(5) In case of flange type motor flange engagement surface is accurately machined. If
contaminant, paint, rust, etc. are found there, remove them surely.
