34CrNiMo6 Alloy steel Helical gear shaft rotary kiln

Helical Gear Shaft

• Overview

Gear profile	Helical/Straight
Material	Carbon steel/Alloy steel
Pressure angle	20°
Helix angle	25°
Accuracy	6-8
Coefficient of displacement	According to drawings

The helical gear shaft is a gear with inclined teeth, which is designed so that multiple teeth are in contact at the same time when engaged, providing smoother, quieter operation and the ability to withstand greater loads and higher speeds. Helical gears produce less noise and wear during operation than spur gears, making them ideal for applications that require high precision and smooth transmission.

• Features

1. Stability and low noise;

2. High bearing capacity

3. Better stress distribution

4. High efficiency

5. High installation accuracy

• Production process
• Forging

Maximum13000 Tons Oil hydraulic press

Through forging, the internal structure of the ingot can be more dense and the mechanical properties are better.

• Rough machining

When the module of the gear shaft is greater than 25, we will add a process – rough teeth. In this way, the hardness and strength of the tooth surface are more uniform and the mechanical properties are better in the subsequent heat treatment

• QT

A: Well electric furnace: through radiation heating, the parts can be heated very evenly, it not only can protect the environment, but also can effectively reduce the deformation of the workpiece. As our leader, an engineer who has been engaged in mechanical manufacturing for 42 years said the biggest problem in mechanical manufacturing is deformation, the deformation of the workpiece can be minimized by heating it in the well furnace;

B: The quenching medium complete: oil, synthetic quencher, water and salt water. According to different materials and process requirements, we will use different medium for quenching and cooling at the fastest cooling speed allowed for the part, and then tempering to achieve the best mechanical properties;

C: Large cooling capacity, there are 450 tons of synthetic quencher and water respectively and we add the cooling circulation system, then the large spare parts can be heat treated;

D: Special furnace:this furnace only has this one workpiece.

• Hobbing

Hobbing is a common and important process for manufacturing helical gear shafts, which can ensure the smoothness and accuracy of the gear transmission, higher production efficiency, improve the surface finish of the product (which has a positive impact on reducing friction, improving lubrication and extending the life of the gear), and improve the mechanical properties of the product.

• Inspection

According to customer requirements, in addition to dimensional inspection, UT inspection, chemical composition inspection and hardness inspection, MT is also required to ensure that there are no defects inside and outside the product.

• Customers comments

Customer support and feedback has always been our driving force
