Problems solved by technology
For a long time, this type of device has been imported from Europe and the United States. Its price is very expensive compared with the price of general instruments and meters, and the product installation and debugging are complicated, and the stability and reliability of the transmission structure are poor. Once a failure occurs, foreign manufacturers generally require repairs. The faulty product needs to be replaced, so it is very time-consuming, which is not conducive to the long-term development of my country's shipbuilding industry

Embodiment Construction
[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0026] Such as Figure 1-10 As shown, the designed pitch transmitter of the present invention consists of housing 3, shell cover 24, end cover 14, sealing core 5, protective tube 9, sprocket 2, chain 4, sprocket shaft 26, spring 7, potentiometer 20 and other components.
[0027] Put the bearing 25 in the groove of the housing 3, put the sprocket 2 on the bearing 25, pass one end of the sprocket shaft 26 through the bearing cover 15, and pass the other end through the sprocket 2, and fix the bearing cover 15 on the shell with screws. body 3. Sleeve 27 is housed on the sprocket shaft 26, and during chain 4 motions, sprocket 2 can find centerline voluntarily.
[0028] The potentiometer 20 is fixed on the positioning plate 19, and there are three grooves on the positioning plate 19. When adjusting the resistance value of the potentiome...

The invention discloses a vane angle signal transmitter. The signal transmitter comprises a housing, a housing cover, a sealing core, a protection tube, a sprocket wheel, a chain and a potentiometer. A sprocket wheel shaft is fixedly connected to the center of the sprocket wheel, and the two ends of the sprocket wheel shaft are respectively connected to the front wall and the rear wall of the housing through a bearing. The sealing core is arranged on the lower wall of the housing, the protection tube sleeves the sealing core, and the sealing core is internally provided with a guide rod. The chain is wound on the sprocket wheel, and is engaged with the sprocket wheel. One end of the chain protrudes from a through hole in the right wall of the housing, and the other end of the chain is connected to the upper end of the guide rod. The lower portion of the guide rod is fixedly connected to an indication wheel, and a spring is arranged between the indication wheel and the sealing core. Indication devices are arranged on the indication wheel and the protection tube. A bearing cover is arranged on the rear wall of the housing. The outer side of the bearing cover is fixedly connected to a positioning disk. The potentiometer is fixedly connected to the positioning disk. The sprocket wheel shaft is connected to an output shaft of the potentiometer through a linkage device. The vane angle signal transmitter is compact in structure, is convenient to assemble, and is stable and reliable.
Description
technical field [0001] The invention relates to a ship propeller signal feedback device, in particular to a propeller angle transmitter for feeding back the rotation angle signal of the ship propeller. Background technique [0002] The propeller angle transmitter is one of the main feedback adjustment devices of the ship's thrust control system. It is mainly composed of a mechanical transmission device and a precision potentiometer, which is converted into a resistance signal through mechanical transmission, and transmitted to the relevant control panel for display and participation in control. The pitch transmitter can also be used for signal feedback adjustment of the main thruster or other similar occasions. For a long time, this type of device has been imported from Europe and the United States. Its price is very expensive compared with the price of general instruments and meters, and the product installation and debugging are complicated, and the stability and reliabil...
