Technical Field
The utility model belongs to the technical field of the generator spare part, concretely relates to bent axle case lid stator outlet structure.
Background
In general generators, an electric machine is used as an important component for converting mechanical energy into electrical energy. For a variable frequency generator, the motor is usually disposed between the crankcase and the start cover, and the crankcase is provided with a structure for the stator to be led out. Above-mentioned structure makes crankcase structure more complicated, increases the crankcase casting mould degree of difficulty.
SUMMERY OF THE UTILITY MODEL
The utility model discloses plan to provide a bent axle case lid stator outlet structure covers the motor setting at the crankcase to cover at the crankcase and set up outlet structure, can effectively reduce the degree of difficulty of crankcase casting mould.
Therefore, the utility model discloses the technical scheme who adopts does: a crank shaft hole is formed in a crank case cover, the front side face of the crank case cover is a case closing face, a boss used for mounting a motor is arranged on the rear side of the crank case cover, the lower end of the rear side of the crank case cover extends backwards to form a wind guide face matched with the lower end of a wind guide cover, the left end of the rear side of the crank case cover extends outwards to form a sealing face matched with the left end of the wind guide cover, a wire outlet hole is formed in the upper end of the sealing face, a wire passing groove is formed in the connecting line of the center of the wire outlet hole and the center of the crank shaft hole, the upper end of the wire passing groove is communicated with the wire outlet hole, and the lower end of the wire passing groove is close to the crank shaft hole.
Preferably, the right side of the wire hole is provided with a wire pressing mounting column for mounting a wire pressing block, the left lower end of the wire hole is provided with a bolt hole protruding forwards, the wire pressing block is arranged on the rear side of the wire hole, one end of the wire pressing block is sleeved on the wire pressing mounting column, and the other end of the wire pressing block is mounted in the bolt hole through a bolt and fixed.
More preferably, the lower end of the wire passing groove is provided with an inclined surface.
More preferably, a protrusion is disposed at a position corresponding to the wire passing groove on the front side of the crankcase cover.
The utility model has the advantages that: the motor is arranged between the crankcase cover and the air guide cover, so that the crankcase cover is not required to be provided with an outlet structure of a motor stator, the difficulty of the crankcase body casting mold can be effectively reduced, and the difficulty of the crankcase cover casting mold is not increased; the crankcase cover is provided with the wire outlet hole and the wire passing groove, so that the stator wire harness passes through the wire outlet hole along the wire passing groove and then directly reaches the upper part of the crankcase body, and the length of the stator wire harness cannot be increased by a circuit of the stator wire harness.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic structural diagram of the present invention.
Detailed Description
The invention will be further described by way of examples with reference to the accompanying drawings:
as shown in fig. 1-2, a stator outlet structure of a crankcase cover is provided with a crank hole 1 on the crankcase cover, and the front side surface of the crankcase cover is a box closing surface 2 contacting with a crankcase body. The rear side of the crankcase cover is provided with a boss 3 for mounting a motor, the lower end of the rear side of the crankcase cover extends backwards to form a wind guide surface 4 matched with the lower end of the wind guide cover, and the left end of the rear side of the crankcase cover extends outwards to form a sealing surface 5 matched with the left end of the wind guide cover, so that the motor is mounted between the crankcase cover and the wind guide cover.
The upper end of the sealing surface 5 is provided with a wire outlet hole 6, a wire passing groove 7 is arranged on a connecting line between the center of the wire outlet hole 6 and the center of the crankshaft hole 1, the upper end of the wire passing groove 7 is communicated with the wire outlet hole 6, the lower end of the wire passing groove 7 is close to the crankshaft hole 1, and a stator wire harness passes through the wire outlet hole 6 along the wire passing groove 7 and then directly reaches the upper part of the crankshaft box body.
In order to prevent the stator wire harness from rotating because of the rotor, the connection between the stator wire harness and other wire harnesses is loosened, a wire pressing structure is arranged at the position of the wire outlet hole 6, and the wire pressing structure is as follows: be provided with the line ball erection column 8 that is used for installing the line ball piece on the right side of wire hole 6, the left lower extreme of wire hole 6 is provided with bellied bolt hole 9 forward, and the line ball piece setting is at the rear side of wire hole 6, and one end suit is on line ball erection column 8, and the bolt hole 9 internal fixation is installed through the bolt to the other end. And one end of the wire pressing block is sleeved on the mounting column, so that the mounting of one bolt can be reduced, and the number of integral parts is reduced.
To prevent the strength around the crankshaft hole 1 from being lowered due to the provision of the thread passing groove 7, a slope 7a is provided at the lower end of the thread passing groove 7.
In order to prevent the wall thickness in the crankcase cover from being reduced due to the arrangement of the wire passing groove 7, thereby influencing the strength of the whole crankcase cover, a bulge 10 is arranged at the front side of the crankcase cover corresponding to the position of the wire passing groove 7.
