As the 17 years steel casting manufacturer that focus on casting girth gear, you are worthy trust.
Choosing the satisfy gith gear manufacturer means choosing quality assurance to avoid the following problems:
The large ring gears of the rotary kiln usually works in low-speed, high-power, dusty, and high-temperature environmental conditions. Therefore, the requirements for the large girth gear are higher than the gear reliability requirements of general transmission mechanisms. Failures will inevitably occur during use. How to solve it? Let’s elaborate on it from the following aspects:
General questions

1.1 Raw material issues

The main reason is that the quality problems of forgings are relatively common.

1.2 Heat treatment issues

The main manifestation is that the heat treatment process is improper and the mechanical properties cannot meet the design requirements.

1.3 Machining issues

Mainly due to the low precision of the machine tool, the single-index milling method for gear hobbing, large wear and tool errors during the tooth cutting process, resulting in excessive chord tooth thickness, common normal line, tooth surface roughness and separation. Uneven quality issues.

1.4 Problems during use and maintenance
 Installation accuracy is not enough
For example, the radial and axial circular runout of the large ring gear is out of tolerance, or there is a measurement error during installation and alignment, or the top clearance and clearance between the large and small gears are out of tolerance, or the contact surface of the large and small gear pairs does not meet the requirements, etc., resulting in actual operation. The large and small gears are in poor working condition.

Improper operation and maintenance
The main manifestation is that the lubricating oil is improperly selected and the lubricating oil used for a long time is not replaced on time, which causes premature pitting corrosion on the tooth surface of the large ring gear.
