Manual Extract: Idler Gear Inspection

The following guide outlines the process for inspecting the idler gear, a critical component in ensuring the machineryu2019s optimal performance.

Inspection Steps

1. Inspect the Idler Gear: Ensure thorough checking for tooth contact, peeling, and pitching.
2. Measure the Idler Gear Shaft: Use a micrometer to determine shaft dimensions. The specified value is 39.959 – 39.980 mm (1.573 – 1.574 inches) for the outside diameter of idler gear A, and 29.959 – 29.980 mm (1.1795 – 1.1803 inches) for the outside diameter of idler gear shafts B and C.
3. Measure the Idler Gear: Utilize a cylinder gauge to measure the bush inner diameter of each idler gear.
4. Calculate the Clearance: Determine clearance based on measurements. The specified clearance for Idler Gear A is 0.025 – 0.066 mm (0.001 – 0.003 inches), and for Idler Gear B and C is 0.020 – 0.062 mm (0.0008 – 0.0024 inches).

Note: The clearance is calculated as the difference between the inner diameter of the idler gear bush and the outer diameter of the idler gear shaft.

Usage Recommendations

• Ensure regular inspection and maintenance per the guidelines to enhance machinery lifespan and performance.
• Utilize precision tools such as micrometers and cylinder gauges for accurate measurements.
• Consult the manual for detailed schematics and additional operational guidance.
