For the power take-off mechanism of diesel engine, the middle part hollow out of described supporting base, its axial cross section is horn-like.
For the power take-off mechanism of diesel engine, the output minor axis between supporting base and flange plate is provided with the shaft shoulder of convex ring shape, and the output minor axis in the supporting base outside is the cone axis that tapering is less than 5, and belt pulley is connected with the cone match of output minor axis by the inner circle taper hole.
For the power take-off mechanism of diesel engine, described belt pulley is mlultiple-groove sheave.
Useful technique effect of the present utility model embodies in the following areas:
1. when the utility model is worked, the radial force that belt pulley carries when outputting power, be passed to the body of motor by output minor axis → bearing → supporting base → flywheel casing, effectively solve by belt pulley output carrying radial force and bent axle, bearing shell are caused to the faults such as off-axis, eccentric wear, simultaneously, flywheel, actuating motor are had to protective action;
2. the utility model is reasonable in design, simple in structure, easy for installation, reliable operation.
The accompanying drawing explanation
