Learn About What Is a Gear Shaft
There are many types of forged shafts. Our Songjie Forging manufacturer has produced a variety of forged shafts, including stepped shaft, hollow shaft, fan shaft, roller axle, marine shaft, transmission shaft, gear shaft, etc., among which The gear shaft is one of the shafts with unique appearance. It is an important part of the entire transmission device and plays an important role in the gearbox.
What Is a Gear Shaft
The gear shaft can be identified quickly. It is generally in the shape of a metal round rod and is a round rod shaft with teeth. A gear shaft refers to a mechanical part that supports a rotating part and rotates with it to transmit motion, torque or bending moment. The gear shaft is a combination of gear and shaft, each section can have different diameters, and has the characteristics of stable performance and high transmission precision.
Gear Shaft Types
1. According to the shape of the axis, it can be divided into crankshaft and straight axis;
2. According to the bearing condition of the shaft, it can be divided into rotating shaft, mandrel and transmission shaft;
3. According to the nature of the gear shaft, it can be divided into three types: parallel shaft, intersecting shaft and staggered shaft.
Gear Shaft Advantages
Gear shafts are used in various fields and play an important role in various fields. They are one of the most important parts in mechanical equipment. It has many advantages, including high transmission efficiency, very suitable for projects requiring speed and strength, long service life, wide application range, constant transmission ratio and continuous and stable operation of mechanical equipment, etc.
Gear Shaft Application
Gear shafts are widely used in automotive, metallurgy, heavy equipment, industrial machinery, electronics, construction, petroleum and medical, etc. It is especially used in various mechanical equipment, such as machine tools, aircraft, gas generators, water pumps, harvesters, coal and agricultural machinery, steamships and fans.
Gear Shaft Working Principle
When the gear shaft is combined with the gear on the other shaft, one of the gears rotates to transmit motion and power, causing the other gear to rotate in a different direction and speed. It works by transferring power or torque from one rotating gear to another through mechanical contact.
Gear shafts are made because the outer diameter of the gears is small, and a gear with a larger diameter rotates more slowly and has more torque than a gear with a smaller diameter. Thus, gear shafts help provide the necessary mechanical advantage to transfer power between different mechanical systems.
Gear Shaft Processing Technology
(1) Forged Gear Shaft
The forging process is to use the blank to forge the shape of the gear shaft with cross wedge rolling technology. The forged gear shaft not only has high precision, small post-processing allowance, but also high production efficiency.
(2) Normalizing
After the forging is finished, the forged shaft material is firstly normalized, and the warm normalizing process is adopted to avoid affecting the performance of the material, and effectively change the disadvantages of general normalizing, and the product quality is stable and reliable. The purpose of this process is to eliminate the internal stress of forging, refine the grain, improve the cutting performance during machining, and prepare for the final heat treatment to effectively reduce heat treatment deformation.
(3) Rough Processing
In the rough machining stage of the gear shaft, the process will be different according to the specifications of the gear shaft required. This stage includes hollowing out, rough turning and drilling, etc., through which most of the machining allowance of the gear shaft is removed.
(4) Flaw Detection
Carry out preliminary flaw detection on the gear shaft to detect whether there are internal cracks, defects or unevenness to ensure the quality of the product.
(5) Quenching And Tempering Treatment
Due to the large cutting force and heat generated during the rough machining of the gear shaft, the gear shaft generates internal stress. We can eliminate the internal stress through quenching and tempering treatment instead of aging treatment, and at the same time obtain the required toughness.
(6) Semi-Finishing
Before the gear shaft is tempered, rough machining is performed; after quenching and tempering, semi-finishing is required. After semi-finishing, the required gear shaft has reached the required specifications.
(7) Quenching
After semi-finishing, the gear shaft is quenched to achieve the required hardness.
(8) Finishing
After quenching, the gear shaft is finished to eliminate quenching deformation.
(9) Inspection
Detect gear shaft specifications, surface, chemical composition, mechanical properties, mechanical properties and flaw detection, etc.
Gear Shaft Supply Range
Gear Shaft Material
Carbon steel, stainless steel, alloy steel, aluminum, tool steel, copper, etc.
Gear Shaft Size Range
Diameters up to 2,50mm
Lengths up to 1000mm
The gear shaft needs regular maintenance. Use gear shaft lubricant to reduce the fatigue and pressure on the gear teeth and the main body, and improve the overall service life of the gear. As a gear shaft manufacturer, Songjie Forging Factory provides a variety of gear shafts, manufacturing gear shafts with higher reliability, service life, mechanical performance and cost performance.
