The key raw material of cycloid hydraulic motor shell is nodular cast iron. The purpose of nodular cast iron quenching is to get pearlite mechanism, and make crystal optimization and mechanism symmetry, so as to improve the compressive strength, strength and wear resistance of parts, and can be used as the prior heat treatment process of induction quenching. Perhaps many small partners for cycloid hydraulic motor understanding is not very deep, then the following to understand the company introduced just mentioned cycloid hydraulic motor to make ductile iron is what it is.

XSM2 series hydraulic motor ultra-low temperature quenching processing technology is the cycloid hydraulic motor heating to eutectoid temperature range, namely 820~860℃, heat insulation 1~4h

(1) High temperature quenching: High temperature quenching process is the cycloid hydraulic horse above heating to the eutectoid temperature range, and generally is 900 ~ 950 ℃, adiabatic 1 ~ 3 h, make base material institutions all body, followed by air cooling, in the eutectoid temperature range, because of the cold quickly get pearlite base material for thin wall castings, high silicon content, should choose air-cooled, or spray cooling, Pearlitic nodular cast iron can be obtained after quenching.

(2) the ultra-low temperature quenching: ultra-low temperature quenching process is to put the cycloid hydraulic motor heating to the eutectoid temperature range, which is 820 ~ 860 ℃, the heat insulation 1 ~ 4 h, make base material body part of martensite, followed by air cooling after ultra-low temperature quenching microstructure of pearlite, the decentralized nodular cast iron, can improve ductility and plasticity of castings.

Characteristics of cycloid hydraulic motor

This kind of motor structure is simple, small size, can be applied to many places, but XSM3 series hydraulic motor oil distribution organization is very easy to be damaged by the load, the total flow of the motor is small, low efficiency, weak ability to work under pressure. When we design the motor, according to the form of lifting tangential rolling bearings, the motor can carry a large tangential force, instead of only applying pressure bearings in some foreign enterprises, so the cycloid hydraulic pressure motor can use some places with relatively large tangential force.

proposed

Because of the output shaft and shell oil distribution precision is not high, prompting axial capacity of oil distribution cycloid hydraulic motor efficiency and mechanical energy is less than the plate of oil distribution cycloid hydraulic motor, generally offer customers, shaft oil distribution cycloid motor work the application of high pressure not higher than 15 mpa, high voltage output shaft is very easy to grind, internal structure and expand the XSM4 series hydraulic motor is leaking.
