Technical Field
[0001] The utility model relates to the field of steering gear structures, in particular to a double-compartment shell structure for a steering gear. Background Art
[0002] A servo is a position (angle) servo drive suitable for control systems that require the angle to be continuously changed and maintained.
[0003] Most of the servos currently sold on the market are in a cabin, and basically the mechanical and electrical components are placed in the same compartment. First of all, from a safety perspective, this does not comply with safety operating regulations. It is easy to cause the operation and wear of the mechanical parts, and the noise will cause certain interference to the operation of the electrical components. In addition, since the mechanical parts themselves will also generate some heat during long-term operation, this will easily cause the temperature in the overall compartment to rise, which will affect the service life of the electrical components and circuit boards. Utility Model Content
[0004] The purpose of the utility model is to provide a double-compartment housing structure for a steering gear, so as to solve the technical problems in the prior art that the operation and wear of mechanical parts in the integrated steering gear compartment and the noise thereof may interfere with the operation of electrical parts.
[0005] The technical solution of the present utility model is: a double-compartment shell structure for a steering gear, comprising a mechanical installation compartment and an electrical installation compartment detachably connected by fasteners, and the mechanical installation compartment and the electrical compartment are both made by an integral molding process; wherein, the mechanical installation compartment comprises a main compartment and a gear compartment, the main compartment is used to accommodate the motor, the gear compartment is used to accommodate the transmission device, and the main compartment and the gear compartment have a common connecting wall, and the connecting wall is provided with a connecting hole for the transmission connection of the mechanical equipment.
[0006] Preferably, the mechanical installation cabin can be filled with high-pressure oil, and the high-pressure oil imparts outward prestress to the mechanical installation cabin.
[0007] Preferably, a side of the gear compartment away from the main compartment is provided with an opening for gear installation, and a detachable end cover is provided at the corresponding opening, and the end cover cooperates with the opening to seal the gear compartment.
[0008] Preferably, the mechanical installation compartment and the electrical installation compartment are both made of stainless steel.
[0009] Preferably, the high-pressure oil enters the mechanical installation compartment through the oil filling hole.
[0010] Preferably, at least one side wall of the mechanical installation compartment is configured as a heat dissipation portion.
[0011] Preferably, the electrical installation cabin is provided with an installation groove on the edge, and ears are formed at both ends of the installation groove along the length direction, and the ears are provided with installation holes along the vertical direction; wherein, the installation holes close to the mechanical installation cabin are used for fastener connection, and the installation holes away from the mechanical installation cabin are used for installing the cover plate.
[0012] Compared with the prior art, the advantages of the present invention are:
[0013] (1) This application disposes the prior art integrated steering gear compartment into two separate electrical installation compartments and mechanical installation compartments, which are connected by fasteners. This ensures that the motors, transmission devices, etc. installed in the mechanical installation compartment will not interfere with the electronic components in the electrical installation compartment.
[0014] (2) The internal sealing setting of the mechanical installation cabin allows it to be filled with high-pressure oil. On the one hand, it gives the mechanical installation cabin wall an outward prestress, enhancing its pressure capacity. On the other hand, it can absorb the heat generated by the operation of the motor and transmission device and lubricate it during operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following is a further detailed description of the present invention in conjunction with specific embodiments:
[0023] like Figure 1The figure shows a dual-compartment housing structure for a steering gear, comprising a mechanical compartment 1 and an electrical compartment 2, detachably connected by bolts and other fasteners. Both the electrical compartment 2 and the mechanical compartment 1 are milled from a single block of stainless steel. The electrical compartment 2 is used to house circuit boards, Hall sensors, and other electrical components, while the mechanical compartment 1 houses the motor and transmission devices such as gears and worm gears.
[0024] like Figure 2 As shown, the mechanical installation compartment 1 includes a main compartment 11 and a gear compartment 12. The main compartment 11 is used to accommodate the motor, and the gear compartment 12 is located adjacent to the main compartment 11 and is used to accommodate the transmission device. The main compartment 11 and the gear compartment 12 share a common wall surface, which is configured as a connecting wall 13. The connecting wall 13 is pre-configured with a connection hole 14 corresponding to the output terminal of the motor in the main compartment 11. The output terminal of the motor passes through the connection hole 14 and is in transmission connection with the transmission device in the gear compartment 12.
[0025] The gear compartment 12 is open at one end away from the main compartment 11, which is used to facilitate the installation of the transmission device. A bolt hole 16 is opened at this location, and an end cover is provided to match the bolt hole 16. After the transmission device is installed, the end cover can be matched with the gear compartment 12 to seal the gear compartment 12.
[0026] like Figure 4 As shown, the electrical installation compartment 2 is provided with an oil filling hole 15, through which high-pressure oil can be filled into the mechanical installation compartment 1. The high-pressure oil applies a prestressed force from the inside out to the wall of the mechanical installation compartment 1, thereby achieving a higher pressure-bearing capacity when the present application is used on a submersible and subjected to water pressure from the outside in.
[0027] Furthermore, the high-pressure oil in contact with the motor and gears not only lubricates their meshing transmission but also absorbs heat generated during operation. Therefore, to cool the high-pressure oil after absorbing heat, at least one sidewall of the mechanical installation compartment 1 is constructed as a heat sink 17. This heat sink 17 has a thinner wall than the other sidewalls, resulting in high heat transfer efficiency between its interior and exterior.
[0028] like Figure 3 As shown, the electrical installation compartment 2 has four mounting slots 21 corresponding to its four edges along the vertical direction. Ears 22 are formed at both ends of any mounting slot 21 along the length direction. The ears 22 have mounting holes 23 along the vertical direction. The mounting holes 23 at the bottom are used for fasteners to pass through to fix the electrical installation compartment 2 to the mechanical installation compartment 1. The mounting holes 23 at the top are used to install the enclosed electrical installation compartment 2. Figure 5 The cover plate 24 is shown.
[0029] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly, and they are not intended to limit the scope of protection of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that fall within the meaning and scope of the equivalent elements of the claims are included in the present invention.
