Ħafna tagħmir jeħtieġ li jkun preċiż, għalhekk huma ta 'valur. Madankollu, meta l-kamin tal-ballun ikun qed jaħdem, it-temperatura għolja se taffettwa l-eżattezza tat-tagħmir, speċjalment xi makkinarju ta '-preċiżjoni għolja. U liema fatturi se jżidu t-temperatura tal-kamin tal-ballun?
The elements of temperature rise are basically these three types: 1. Pre-pressure 2. Smooth 3. Pre-tensioning
1. The influence of pre-pressure
In order to prevent any loss of step of the mechanical transmission system, it is important to improve the rigidity of the nut. However, to improve the rigidity of the nut, it is necessary to make the preload of the nut reach a certain level. Applying pre-pressure to the nut will increase the conflicting torque of the screw and increase the temperature rise during operation.
HIWIN jippromwovi li l-preload medju u tqil huwa 8 fil-mija tat-tagħbija dinamika; il-preload medju huwa 6 fil-mija sa 8 fil-mija; il-preload medju u ħafif huwa 4 fil-mija sa 6 fil-mija; il-preload ħafif huwa taħt l-4 fil-mija, u l-preload itqal m'għandux jaqbeż l-10 fil-mija It-tagħbija dinamika biex tikseb l-aħjar ħajja u effett ta 'żieda fit-temperatura aktar baxxa.
2. The effect of smoothness
The selection of smooth oil directly affects the temperature rise of the ball screw. HIWIN ball screw must be smoothed with oil or grease. Generally, it is recommended to use bearing lubricating oil as ball screw lubricating oil, and for grease, it is recommended to use lithium soap-based grease. The choice of oil viscosity is based on operating speed, operating temperature and load conditions.
It is best to choose low-viscosity oil when the working condition is high speed and low load; when low speed and high load, it is recommended to use high viscosity oil. Generally speaking, it is recommended to use the viscosity index scale of 32-68 cSt (ISO VG 32-68) (DIN 51519) meta ż-żejt lubrikanti huwa 40grad; Il-kumpens isir billi -ġbid minn qabel; u l-valur immirat tal-kumpens ta' qabel -ġbid huwa l-valur T negattiv indikat fuq it-tpinġija. Pretensjoni eċċessiva se taħraq il-bearing ta 'appoġġ, għalhekk HIWIN favur l-użu ta' valur ta 'pretensjoni ta' inqas minn 5grad, iżda mhuwiex adattat għall-pretensjoni jekk id-dijametru tal-kamin jaqbeż il-50mm; dijametru tal-kamin kbir jeħtieġ forza ta 'pretensjoni kbira, li twassal għall-appoġġ Il-bearing jissaħħan żżejjed u jinħaraq.
