What is the working principle of the engine oil pressure sensor?

The working principle of the engine oil pressure sensor is: 1. The amplified pressure signal is connected to the oil pressure gauge through the signal line, changing the current ratio between the two coils inside the oil pressure gauge, thereby indicating the engine's oil pressure; 2. The pressure signal, after voltage and current amplification, is also compared with the alarm voltage set in the alarm circuit. When it falls below the alarm voltage, the alarm circuit outputs an alarm signal and lights up the warning light through the alarm line. The solutions for excessively high engine oil pressure are: 1. Adjust the clearance between the shaft neck and bearing of the pressure lubrication part; 2. Clean the oil pipes and oil passages, and maintain the filter; 3. Select the appropriate oil grade; 4. Replace the oil with the appropriate viscosity; 5. Check and adjust the pressure relief valve on the oil pump test bench to ensure the oil pressure meets the specified requirements.

What are the main failure modes of closed soft-tooth-surface gear transmission?

The main failure modes of closed soft-tooth-surface gear transmission are: 1. Tooth breakage: Tooth breakage usually occurs in two situations, one is fatigue breakage caused by repeated bending stress and stress concentration, and the other is overload breakage caused by sudden severe overload or impact load; 2. Plastic deformation: Generally occurs on tooth surfaces with low hardness, but can also appear on high-hardness gears under heavy loads; 3. Pitting corrosion: During gear operation, under the repeated action of alternating contact stress at the meshing point, small cracks will form on the tooth surface near the pitch line. As these cracks expand, they will cause small pieces of metal to peel off, a phenomenon known as pitting corrosion; 4. Tooth surface adhesion: For high-speed and heavy-load gear transmissions, tooth surface adhesion is prone to occur. Additionally, low-speed and heavy-load heavy-duty gear transmissions can also experience tooth surface adhesion failure, known as cold adhesion.
