Male Threaded Custom Non Standard Cantilever Shaft 3D Printing Device Use

Custom service reasonable price high precision cantilever Shaft both end male thread type for 3D printing device

Application of cantilever Pin in Industrial Automation parts:

In the application of machine tool spindles, the cantilever pin external thread mounting and external thread type, double row precision cylindrical roller bearings are also used, usually in combination with precision angular contact ball bearings or thrust bearings. These bearings can withstand large radial loads and allow for higher rotational speeds. The two rows of rollers in the bearing are arranged in an intersecting manner. The wave frequency is greatly increased compared with the single row bearing, and the amplitude is reduced by 60%-70%. These bearings usually come in two forms: NN30, NN30K two series bearing inner ring with ribs, outer ring can be separated;

NNU49, NNU49K two series bearing outer ring with ribs, inner ring can be separated, of which NN30K and NNU49K series The inner ring is a tapered hole (taper 1:12), which cooperates with the tapered journal of the main shaft. The inner ring is axially moved to make the inner ring expand. The cantilever pin is embedded in the external thread to install the external thread type, so that the bearing clearance can be Reduce or even pre-tighten the bearing (negative clearance state).

Commonly used material

40 cr

40Cr is a commonly used material for shaft parts, it is cheap after quenching and tempering (or normalizing), can get better cutting performance, and can get higher strength and toughness and other comprehensive mechanical properties, after quenching surface hardness up to 45 ~ 52HRC.

40Cr and other alloy structural steel is suitable for shaft parts with medium accuracy and high rotating speed. After quenching and tempering, this kind of steel has better comprehensive mechanical properties.

40Cr steel is one of the most widely used steels in the machinery industry.After tempering and tempering treatment, it has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity.Good steel hardenability, when water quench hardening to Ф 28 ~ 60 mm, when oil quenching hardening to Ф 15 ~ 40 mm.This steel is suitable for cyanidation and high frequency quenching in addition to quenching and tempering.When the hardness is HB174 ~ 229, the relative machinability is 60%.
