Gear Shaft



What Is Gear Shaft

Gear shaft refers to a mechanical part that supports a rotating part and rotates with it to transmit motion, torque or bending moment. It is generally in the shape of a metal round rod, and each section can have different diameters. The rotating parts in the machine are mounted on the shaft. More than one million times a month MINGHE Hardware delivers a new gear shaft machined custom component, including hundreds of thousands made in steel. Each individual component is produced with a focus on top productivity, and on maintaining a supply of components that never runs dry. This assurance is backed by over a 30 years of experience with the cutting characteristics of hundreds of different gear shaft types, each with unique processing requirements we have mastered.

The Classification Of Gear Shaft

According to the shape of the axis, the shaft can be divided into two types: crankshaft and straight shaft. According to the bearing condition of the shaft, it can be divided into:

  • The rotating shaft, which bears both bending moment and torque during work, is the most common shaft in machinery, such as the shaft in various reducers.
  • The mandrel is used to support the rotating parts and only bear the bending moment and not transmit the torque. Some mandrels rotate, such as the axle of railway vehicles, and some mandrels do not rotate, such as the axle supporting the pulley.
  • The drive shaft is mainly used to transmit torque without bearing the bending moment, such as the long optical shaft in the moving mechanism of the crane, the drive shaft of the automobile, etc.

Gear Shaft Design And Application

In the design, the use of gear shafts is generally nothing more than the following situations:

  • The gear shaft is generally a pinion (a gear with a small number of teeth).
  • The gear shaft is generally in the high-speed level (that is, the low-torque level).
  • Gear shafts are generally seldom used as sliding gears for shifting speeds, they are generally fixed-running gears. First, because they are in the high-speed stage, their high speeds are not suitable for sliding shifting.
  • The gear shaft is a combination of shaft and gear. However, in the design, the length of the shaft should be shortened as much as possible. If it is too long, it is not conducive to the upper hobbing machine. The second is that the support of the shaft is too long and the shaft needs to be thickened. And increase the mechanical strength (such as rigidity, deflection, bending resistance, etc.).

Product Detail

Our factory has more than 20 years of experience in gear shaft processing and production. It is good at processing various types of high-precision gear shafts. The products are exported to many countries and regions overseas. There are different processing techniques for gear shafts with different precision requirements. For gear shafts with general precision, our factory’s processing technology is: blank blanking → rough turning → quenching and tempering treatment → finishing turning gear blank → machining keyway → hobbing → tooth surface quenching → gear grinding → inspection. For some gear shafts with high precision requirements for drawings or samples, the special technology adopted by our factory can fully meet the requirements of customers.
