Embodiment Construction

[0016] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0017] Please refer to the attached Figures 1 to 5 , the embodiment of the present invention includes:

[0018] A non-contact transmission indicating mechanism for the pitch feedback of ship controllable propellers, such as figure 1 with figure 2 As shown, the feedback loop 1 is installed on the pitch control propeller shaft system, and is rigidly connected with the axially movable parts inside the shaft system. The axial moving parts inside the system make translational movement in the axial direction.

[0019] The non-contact transmission indicating mechanism fixes the mounting support 10 on the hull plate through bolts 15. When installing...

Abstract

The invention relates to a non-contact transmission indicating mechanism for the screw pitch feedback of a ship controllable-pitch propeller, and relates to the field of a device of the screw pitch feedback of the ship controllable-pitch propeller. The non-contact transmission indicating mechanism comprises a feedback loop, a magnet, a crank, a potential sensor, a scale plate and a pointer; the feedback loop is installed on a controllable-pitch propeller shaft of a ship; the potential sensor is arranged on a mounting supporting seat, and the pointer is installed on a central spindle of the potential sensor in a sleeved mode; the pointer is matched with the scale plate on the mounting supporting seat in an indicating mode; the central spindle of the potential sensor is further coaxially sleeved with the crank; the magnet is fixed to the crank; a non-contact magnetic attraction fit is maintained between the magnet and the feedback loop; the synchronous movement is maintained between thefeedback loop and the magnet by the magnetic attraction; and the vertical droop state of the feedback loop corresponds to an initial scale state of the scale plate. The non-contact transmission indicating mechanism has a simple and compact structure and is convenient to install and debug, more importantly, parts have no abrasion, the service life is long, and zero maintenance or low maintenance isachieved.

Description

technical field [0001] The invention relates to the field of pitch feedback devices for pitch control propellers of ships, in particular to a non-contact transmission indicating mechanism for pitch feedback of pitch control propellers of ships. Background technique [0002] During the operation of the ship controllable pitch propeller, it is necessary to monitor the pitch value of the underwater controllable pitch propeller blade at all times, and convert the mechanical pitch value into an electrical signal through a set of mechanical transmission indicating mechanism and position sensor, which can be used by the display instrument on the ship to display the pitch value. In the traditional mechanical transmission indicating mechanism, the feedback loop installed on the rotating shaft system is always in contact with the transmission parts of the indicating mechanism, so there is a problem of continuous wear of the parts. Contents of the invention [0003] The main technica...
