Abstract

PURPOSE: To provide an arrangement for electric chain block, in which main framas are disposed on both sides of the load line, and rigidity of the main frames is increased through provision of an intermediate plate which also serves as support for bearing for a portion of reduction gears, whereby distortion or deformation of the gear box can be prevented, and the entire structure of the chain block can be simplified.
CONSTITUTION: Main frames 2, 4 are disposed concentrically with a predetermined interval from each other, by means of stud bolt 21 threaded into flange portion 20 formed around outer peripheral portion of housing of motor 1. Rigidity of main frame 5 is increased by shaping the same by way of drawing, and it is fixed to the main frame 4 by means of the common fastening bolt, so that their positional relationship can be made accurate. On the other hand, an intermediate plate 32 is provided for serving as cover for gears and also as support for gears 3 operatively connected with motor shaft 6. One end of the intermediate plate 32 is engaged with the outer surface of bearing protruded outwards of the main frame 4, while the other end is fixed by stud bolt. Thus, structure of the main frames can be simplified. At the same time, a large load is supported by main frames 2, 4, so that rigidity of the entire structure of the gear box can be increased
