Shaft parts of the mechanical processing technology related to what?

Release date: 2016-11-28 Author: Click:

Shaft parts, it is a common part of the machine is also a very important part, it can play a supporting role in the transmission parts, and can transmit torque.

Shaft parts of the technical requirements and treatment, for us, is to understand the content of a large-scale machining, it is the specific content of what is it? Then look at the following.

Shaft parts of the technical requirements, generally have the following aspects, as follows:

1. Diameter accuracy, geometric accuracy

On the shaft, it is important to support the journal and the journal. The diameter accuracy is IT5-IT9, and the shape accuracy should be within the diameter tolerances, and its requirements are higher than the diameter accuracy.

Mutual position accuracy

If the axis is normal accuracy, then its radial circle beating, if you want to support the journal bearing journal, generally regarded as 0.01-0.03mm. And the high-precision axis is 0.001-0.005 mm. If there are special requirements, it should be clearly stated.

2. Surface roughness

Because the precision of the machine, the speed and other factors, resulting in shaft parts of the surface roughness requirements are different. Support journal surface roughness of 0.16-0.63um, with the journal of 0.63-2.5um.

3. Spindle material, blank and heat treatment

Shaft parts, the commonly used material is 45 steel, and through normalizing, annealing, quenching and tempering and quenching of these treatments, to obtain a certain strength, hardness, wear resistance and toughness.

For high-speed shaft parts, alloy structural steel can be used because it improves the wear resistance and fatigue resistance after heat treatment. Mechanical finishing

Spindle rough is generally used forging and round bar, which can reduce the amount of cutting, and can improve the mechanical properties of materials.
