(America rack cylinder,produced by Hengyu Hydraulic Cylinder Factory）

rack cylinder are widely used in America，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed rack cylinder for customers from America.

Introduction to rack cylinder:

The meaning of the rack cylinder model marked by the rack cylinder manufacturer: for example, 160/100-1150, its meaning: from a professional point of view, 160 refers to the rack cylinder diameter, which is 160mm, and the 100 behind refers to the rod diameter, which is 100mm. The 1150 refers to the rack cylinder stroke, which is 1150mm. Therefore, on this point, we should have a correct understanding and can not make mistakes.

In recent years, the processing process of the rack cylinder generally adopts the rolling method, which is a pressure finishing processing, which uses the cold plastic characteristics of the metal at room temperature, and uses the rolling tool to exert a certain pressure on the surface of the workpiece, so that the surface metal of the workpiece produces plastic flow, and fills in the low concave trough of the original residue, and the roughness value of the workpiece surface is reduced. Due to the plastic deformation of the rolled surface metal, the surface tissue is cold hardened and the grain is fine, forming a dense fiber, and forming a residual stress layer, and the hardness and strength are increased, thus improving the wear resistance, corrosion resistance and compatibility of the workpiece surface. Rolling is a plastic machining method without cutting.

Factors that should be considered when selecting the oil seal in the rack cylinder: some specific factors should be taken into account when selecting the oil seal in the rack cylinder, so as to have correct consideration and get accurate results, and then avoid wrong selection. The factors and aspects that should be taken into account are eight: rack cylinder diameter, piston rod diameter, piston rod and piston groove size, rack cylinder working pressure, rack cylinder movement speed, hydraulic system oil temperature and rack cylinder working environment.

The piston rod of the rack cylinder has two kinds of solid rod and hollow rod, and one end of the hollow piston rod needs to be set aside for welding and heat treatment. The solid piston rod material is 35, 45 steel, and the hollow piston rod material is 35, 45 seamless steel pipe. After rough machining, the piston rod is conditioned to 229~285HB in India, and if necessary, the hardness is 45~55HRC after high-frequency quenching.

Answers to some questions about rack cylinder:

The inner diameter of the injection cylinder is 203.2mm and the diameter of the screw is 63.5mm. What is the enhancement ratio?
Oil pressure multiplied by the cross-sectional area of the cylinder is equal to the theoretical output force value, and then multiplied by the efficiency of the cylinder is equal to the actual output force value, and the oil pressure can be calculated by inverting the value input.

What diameter cylinder is needed for a force of 5 tons?
It depends on the pressure of your system pump. If the normal working pressure of the system is about 8MPa, then the diameter of the cylinder should be 100 mm.
