Description
Technical Field
The utility model relates to a frame of marine generator, in particular to but the external diameter size of reducing frame to have the frame body who subtracts heavy effect concurrently.
Background
The engine base body of the marine generator consists of an iron core engine base, a driving end cover chamber and a non-driving end cover chamber, wherein a driving end iron core pressing ring is arranged at the driving end of the iron core engine base, a non-driving end iron core pressing ring is arranged at the non-driving end of the iron core engine base, a rib plate is connected between the driving end iron core pressing ring and the non-driving end iron core pressing ring, and the two pressing rings and the rib plate form the outline of an external frame of the whole engine base body; in the existing base, ventilation openings are arranged on a pressure ring at the outer side of the joint of the pressure ring and a rib plate at equal intervals in a radian manner and are used for ventilating and cooling the back of a stator, the ventilation openings are arranged outside the vertical surface of the annular pressure ring, and the structural form of the connecting rib plate is arranged inside the vertical surface of the annular pressure ring, so that the annular pressure ring has a certain width; the iron core base is connected with the end cover chambers at two ends through the compression ring to form the base body, so that the size of the whole motor body is determined to be generally larger; however, when the installation space of the marine motor is limited, the size of the conventional motor base body is large, and when the installation requirement of the motor cannot be met, how to reduce the whole motor base body becomes a problem to be solved on site.
Disclosure of Invention
The utility model provides a but reduce external diameter size and have the frame body that subtracts heavy effect concurrently has solved the technical problem who how to reduce the frame body.
The utility model discloses a solve above technical problem through following technical scheme:
a machine base body capable of reducing the outer diameter size and having a weight reduction effect comprises a drive end iron core pressing ring and a non-drive end iron core pressing ring, wherein connecting rib plates are arranged between the drive end iron core pressing ring and the non-drive end iron core pressing ring at equal intervals; and a non-drive end iron core pressure ring connecting bolt hole is arranged on a non-drive end iron core pressure ring outside an air inlet at the back of the non-drive end stator.
