Combined shell for air-cooled servo motor

Abstract

The invention discloses a combined shell for an air-cooled servo motor, the shell comprises a main shell and a rear hood, both the main shell and the rear hood are aluminum extrusion molding parts with pipeline structures, the inner side surface of the main shell is an annular surface, and the outer side surface of the main shell is defined by four rectangular surfaces and four arc-shaped surfaces. A main air duct area is formed between each arc-shaped surface and the annular surface, four ventilation holes are formed in each main air duct area, an auxiliary air duct area is formed between each rectangular surface and the annular surface, and a plurality of regular hexagonal through holes are formed in each auxiliary air duct area. The outer ring outline and the inner ring outline of the rear hood are rounded squares; the combined shell has the advantages that on the basis of a good cooling effect, the structure is simple, the manufacturing cost is low, the combined shell is not affected by mold abrasion and is easy to assemble, when meeting numerous and miscellaneous customization requirements, the mold does not need to be opened again, and the customization difficulty of the air-cooled servo motor is reduced.

Description

technical field [0001] The invention relates to a combined casing, in particular to a combined casing for an air-cooled servo motor. Background technique [0002] In the field of servo motor design, high efficiency, energy saving and material saving have always been the goals pursued by designers. However, limited by design experience and design technology, the shell structures of air-cooled servo motors currently on the market are either simple in structure but poor in cooling effect, or good in cooling effect but relatively complex in structure. Because the cooling effect of the air-cooled servo motor is one of its important technical indicators, it directly affects the performance of the air-cooled servo motor. Therefore, the current shell structure with a simple structure but poor cooling effect has basically been eliminated, and the air-cooled servo motor mainly uses The shell structure is relatively complex, so that the manufacturing cost remains high. In addition, w...

However, limited by design experience and design technology, the shell structures of air-cooled servo motors currently on the market are either simple in structure but poor in cooling effect, or better in cooling effect but more complex in structure

Because the cooling effect of the air-cooled servo motor is one of its important technical indicators, it directly affects the performance of the air-cooled servo motor. Therefore, the current shell structure with a simple structure but poor cooling effect has basically been eliminated, and the air-cooled servo motor mainly uses The shell structure is relatively complex, so that the manufacturing cost remains high

In addition, when the shell mold of the air-cooled servo motor is used for a period of time, it is inevitable that there will be slight wear and tear, and the fit between the main structure of the servo motor and the shell will drop sharply during assembly, the assembly cost will increase significantly, and the quality control of the whole machine will become more difficult.

At the same time, when the air-cooled servo motor is faced with various customization requirements, its complex structure shell is less modifiable. In order to meet customer needs, the mold can only be re-opened, which requires high cost
