Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slip amount adjusting device used when slipping a clutch of a marine gear for a ship to make it travel at a very low speed.

[0002]

2. Description of the Related Art In a ship equipped with a marine gear for a ship, such as a fishing boat, during fishing work such as trolling fishing,
The engine speed may be reduced and the marine gear clutch may be slipped while navigating at a very low speed. Wind speed at this time,
A controller (rotation setting device) connected to a control device installed in the steering room is used so that the cruising speed can be adjusted outside the steering room while observing the tidal current, waves, fishing conditions, and the like. FIG. 3 shows a conventionally used slip amount adjusting device for a marine gear for a ship, which controls a solenoid 2 for hydraulically controlling a clutch of a marine gear 1 by a controller 3 and a control box 4. That is, the variable resistor 3a of the controller 3
The comparator 8 detects the actual rotation speed of the pickup 5 from the marine gear 1 and feeds it back to the converted voltage via the waveform shaper 6 and the F / V converter 7 in the control box 4. After making a comparison by means of the above, it is sent to the solenoid 2 via the PID control circuit and the PWM control circuit for control.

[0003]

By the way, the controller 3 is of a normal dial type in order to rotate the variable resistor 3a, and the dial control range width is about 300 degrees, which is a scale of 0 to 100. It is allocated in.
In the related art, since the variable resistor 3a is used in the full range, the input rotation speed is changed for the convenience of the user although the rotation speed (screw rotation speed) range to be input is assumed or limited in advance. At that time, the operation width of the variable resistor 3a was changed, and the usability was significantly reduced.

That is, the input screw rotational speed is the engine rotational speed divided by the reduction ratio, and the engine rotational speed is set to, for example, 500 rpm to 15 depending on the type of fishing and the type of user's business.
It is selected in 00 rpm, and the reduction ratio is about 2.0 ~
Since it can be selected in the range of 4.0, therefore, the screw rotation speed is selected from 125 rpm to 750 rpm, but as shown in FIG. When the width is set to the full range (300 degrees) like A,
When it becomes necessary to use the screw rotation speed of 125 rpm, the control range width is narrowed to 60 degrees, as in B, and the usability becomes very poor. The present invention solves the above-mentioned inconvenience in the conventional device, and provides a user-friendly marine gear slip amount adjusting device that can always set the dial control range width to the full range regardless of how the screw rotation speed is set. The purpose is to do.

SUMMARY OF THE INVENTION To achieve the above object, a marine gear slip amount adjusting device of the present invention has a solenoid for hydraulically controlling a clutch of a marine gear, a voltage set by a variable resistor of a controller, and the marine gear. In a slip amount adjusting device for a marine gear for a ship, which compares the fed-back converted voltage with more feedback and controls it through a PID control circuit and a PWM control circuit, a trimmer for adjusting a control range width in series with a variable resistor of the controller. It is characterized by connecting.

[0006]

[Operation] With the slip amount adjusting device for a marine gear of the present invention having the above-described configuration, even when the user changes the initially set screw rotational speed from the initial rotational speed according to the type of fishing, the adjustment trimmer is used. If adjusted, the voltage with respect to the screw rotation speed is divided, and the full range can be changed according to the changed rotation speed, and the full range can be used at any rotation speed. Therefore, fine screw rotation adjustment can be easily performed.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a slip amount adjusting device for a marine gear of the present invention will be described in detail with reference to FIG. 1. However, assuming that the same reference numerals as those in FIG. The quantity adjusting device controls the solenoid 2 for hydraulically controlling the clutch of the marine gear 1 by the controller 3 and the control box 4, that is, the voltage set by the variable resistor 3a of the controller 3 and the pickup 5 from the marine gear 1. The rotation speed is detected and fed back, and after being compared with the converted voltage converted into a voltage through the waveform shaper 6 and the F / V converter 7 in the control box 4 by the comparator 8, this is compared with the PID control circuit 9 and the PWM control. Circuit 1
A control range width adjusting trimmer 11 is connected in series with the variable resistor 3a of the controller 3 in the case where the solenoid 2 is controlled to feed through 0. The trimmer 11 for adjustment is installed in the controller 3 or the control box 4 at a place where it is easy to operate.

In the slip amount adjusting device for a marine gear for a marine vessel of the present invention having the above-described structure, the screw rotation speed initially set by the user is set to, for example, 750 r depending on the type of fishing.
Even when changing from pm to 125 rpm, the voltage for the screw rotation speed in FIG. 2 is divided by adjusting the adjusting trimmer 11, and the full range (300 degrees) can be changed from a to b in FIG. 2, that is, 125 rpm. But it can be used in the full range (300 degrees). Therefore, fine screw rotation adjustment can be easily performed.
