Problems solved by technology

The base and iron core of this cold press assembly structure need to process key grooves, and then rivet the keys in the key grooves of the base. The support ribs distributed radially and discretely around the seat circle are easy to ellipse deformation, which increases the difficulty of cold press assembly

Embodiment Construction

[0018] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:

[0019] Such as Figure 1~4 As shown, the present invention mainly includes a machine base 1 and an iron core 2, the stator iron core 2 is set inside the machine base 1, and the machine base 1 and the stator iron core 2 are interference fit.

[0020] Such as Figure 1~2 As shown, the machine base 1 is a cage-shaped support rib structure, including two upper and lower machine base bottom plates 4 parallel to each other, and the two machine base bottom plates 4 are connected by a plurality of machine base support ribs 3 . A plurality of machine base support ribs 3 are evenly distributed along the circumferential direction of the machine base 1 .

[0021] A group of cooling mechanisms is arranged between every two machine base support ribs 3 , and each group of cooling mechanisms includes a plurality of cooling water pipes 5 , and the cooling water pipes...

Abstract

The invention relates to a motor stator iron core outer press fitting structure with pipes distributed on the periphery, in particular to a hot press fitting structure of a motor stator iron core hot sleeve machine base with pipes distributed on the periphery and belongs to the technical field of motors. The motor stator iron core outer press fitting structure with the pipes distributed on the periphery comprises a machine base and an iron core. The stator iron core is arranged in the machine base in a sleeved mode. The machine base is in interference fit with the stator iron core. The machine base is of a cage-shaped supporting rib structure and comprises an upper machine base bottom plate and a lower machine base bottom plate which are parallel to each other. Multiple machine base supporting ribs are used for connecting the upper machine base bottom plate and the lower machine base bottom plate. The stator iron core is of the cage-shaped supporting rib structure and comprises an upper stator iron core bottom plate and a lower stator iron core bottom plate which are parallel to each other. The upper stator iron core bottom plate is connected with the lower stator iron core bottom plate through stator iron core supporting ribs. The motor stator iron core outer press fitting structure is simple, compact and reasonable, the iron core is arranged in the heating machine base in a sleeved mode, the iron core supporting ribs are in interference fit with the machine base supporting ribs, key grooves do not need to be machined in the machine base and the iron core, the motor stator iron core outer press fitting structure is convenient to machine and arrangement in a sleeved mode is easy to achieve.

Description

technical field [0001] The invention relates to an outer press-fitting structure of a stator core of a motor with surrounding tubes, in particular a heat-pressing structure for a heat-fitting base of the stator core of a motor with surrounding tubes, and belongs to the technical field of motors. Background technique [0002] At present, the external press-fitting structure of the stator core of the surrounding tube-distributed motor adopts a cold-pressing structure. After the iron core is inserted into the machine base, the iron core is pressed into place by a press. The machine base and the iron core are clearance fit, and the two are connected by a key. Transmitting torque and circumferential positioning. The base and iron core of this cold press assembly structure need to process key grooves, and then rivet the keys in the key grooves of the base. The supporting ribs distributed radially and discretely around the seat circumference are prone to elliptical deformation, wh...
