Description

Technical Field

[0001] This utility model relates to the field of underwater servo motor technology, and in particular to a compact servo motor. Background Technology

[0002] Underwater propulsion is one of the key technologies for underwater vehicles. Underwater servos are widely used in autonomous underwater robots, enabling them to turn and pitch by rotating their blades. With increasing global efforts to develop marine resources, the demand for high-performance underwater servos is growing, placing increasingly higher demands on propulsion motor systems.

[0003] In existing technologies, resolvers are directly stacked and installed on top of turbines, which greatly increases the overall size of the servo. Moreover, in existing technologies, resolvers are simply clamped onto the top of turbines with a tight fit, making disassembly and assembly very difficult and inconvenient for maintenance and replacement. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a compact servo motor that has a compact structure, smaller size, and is easier to assemble and disassemble.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a compact servo motor having a housing, wherein a resolver, a turbine, and an output shaft are provided in the housing, the upper part of the turbine is provided with a mounting countersunk hole, the resolver is embedded in the mounting countersunk hole by a mounting assembly and is fitted onto a central column in the mounting countersunk hole, the upper part of the turbine is provided with a cover plate, the mounting assembly includes a resolver mounting plate and a resolver pressure plate, the resolver mounting plate is disposed at the lower part of the resolver, and the resolver is fixed to the cover plate by the resolver pressure plates on both sides.

[0006] In the above technical solution, the resolver mounting plate is L-shaped.

[0007] In the above technical solution, the turbine and the output shaft are integrally formed, and a front bearing is provided between the output shaft and the inner side of the housing.

[0008] In the above technical solution, the resolver mounting plate is fitted onto the central column, and a rear bearing is provided between the resolver mounting plate and the central column.

[0009] In the above technical solution, the lower inner side of the resolver pressure plate is provided with a locking tongue, and the outer periphery of the resolver is provided with a locking groove that cooperates with the locking tongue.

[0010] In the above technical solution, the cover plate is provided with a pressure plate groove, and the rotary pressure plate is embedded in the pressure plate groove and fixed by bolts.

[0011] In summary, the advantages of the technical solution of this utility model compared with traditional technical means are as follows: This utility model provides a mounting countersunk hole on the upper part of the turbine, so that the resolver can be embedded in the turbine, greatly reducing the volume required for installation, making the internal structure of the servo motor more compact and the overall volume smaller.

[0012] Moreover, the resolver is fixed to the cover plate by the resolver pressure plate, and can be disassembled and installed by turning the bolts on it, making it very convenient to repair and replace parts. Attached Figure Description
