Description

Technical Field

[0001] The invention relates to the technical field of angle encoder adjustment, and in particular to a tooling and an adjustment method for adjusting a distributed angle encoder for a marine low-speed diesel engine. Background Art

[0002] Angle encoders are used on marine low-speed diesel engines to measure angles, determine steering, and measure speed. This is a very critical device that determines whether the diesel engine can run correctly. Angle encoders commonly used in marine diesel engines are divided into integrated angle encoders and distributed angle encoders. The former is integrated at the free end, and the latter is an angle encoder system composed of eight sensors such as Q1A, MMA, MSA, Q2A, Q1B, MMB, MSB, Q2B installed in six junction boxes and distributed on the flywheel. Due to the large number of sensors, the adjustment process is cumbersome and the accuracy requirements are very high, which brings great trouble to the technicians who adjust the distributed angle encoders and takes a lot of time to adjust. Summary of the invention

[0005] Furthermore, the positioning area is a rectangular groove that is recessed inwardly on the top surface of the tooling body; a mark is provided in the rectangular groove, and the Q1 sensor and the Q2 sensor are inserted into corresponding positions in the rectangular groove according to the mark.

[0006] Furthermore, the positioning area is a strip groove that is opened in a direction perpendicular to the flywheel surface and passes through the top surface of the tooling body; a mark is provided in the strip groove, and the Q1 sensor and the Q2 sensor are inserted into corresponding positions in the rectangular groove according to the mark.

[0007] Furthermore, the thickness of the tool body is 1 cm to 3 cm.

The method for adjusting a distributed angle encoder for a low-speed marine diesel engine uses a tool for adjusting a distributed angle encoder for a low-speed marine diesel engine, and comprises the following steps:

[0009] Step 1: Keep the vehicle in the forward direction, turn the car to 0 degrees, adjust the position of the MMA sensor, set the MMA sensor at the edge of the trigger ring, and put it in the trigger state;

[0010] Step 2: Keep the flywheel in place and clamp the tool body onto the flywheel teeth through the tooth groove at the bottom;
