Description

Technical Field

[0001] This utility model relates to the field of motors, and in particular to a corrosion-resistant marine motor. Background Technology

[0002] A cycloidal hydraulic motor is a device that converts hydraulic energy into mechanical energy. It is a commonly used actuator in hydraulic systems and is widely used in engineering machinery, agricultural machinery, and other fields. The flow distribution mechanism of a cycloidal hydraulic motor consists of an output shaft and a housing. A certain number of flow distribution grooves are machined on the outer circumference of the output shaft, and a varying number of flow distribution channels are distributed inside the housing at the point of contact with the output shaft. During operation, the flow distribution mechanism connects the motor's inlet port to the inlet chamber of the stator-rotor pair, and also connects the stator-rotor's return chamber to the motor's return port. When pressurized fluid enters the inlet chamber of the stator-rotor pair from the motor's inlet port, its volume continuously expands. Simultaneously, fluid in the return chamber of the stator-rotor pair flows back from the motor's return port. During this process, the rotor in the stator-rotor pair is driven to rotate by the pressure difference between the inlet and return chambers. This rotation is transmitted to the output shaft via the drive shaft, thus realizing the conversion of hydraulic energy into mechanical energy. At the same time, the flow distribution grooves on the output shaft are driven to rotate synchronously by the drive shaft. With continuous flow distribution through the flow distribution grooves, the motor continuously outputs torque and speed.

[0003] However, the housing of existing cycloidal hydraulic motors is basically made of castings. If used in seawater, the outer casting is usually coated with anti-corrosion paint. In actual use, the product still has the problem of rusting.

[0004] Therefore, it is necessary to develop new types of marine motors with improved corrosion resistance. Utility Model Content

[0005] Purpose of the utility model: In view of the shortcomings and defects of the existing technology, this utility model provides a corrosion-resistant marine motor, which adopts multiple seals, simplifies the internal structure, and improves the corrosion resistance.

[0006] Technical solution: The present invention relates to a corrosion-resistant marine motor, characterized in that: it includes a cycloidal motor, the cycloidal motor having a body shell made of 316L stainless steel, the front cover of the body shell having a double shaft seal structure, and the rear cover of the body shell having two joints, the joints adopting a sealing structure of combined gaskets + double O-rings.

[0007] The cycloidal motor is equipped with an output shaft that extends out of the front cover.

[0008] The output shaft of the cycloidal motor is connected to a bearing.

[0009] The front cover of the shell includes front cover one and front cover two.

[0010] The front cover one and the front cover two are respectively provided with shaft seal one and shaft seal two.
