Ní mór go leor trealamh a bheith beacht, mar sin tá siad luachmhar. Mar sin féin, nuair a bhíonn an scriú liathróid i bhfeidhm, beidh tionchar ag an teocht ard ar chruinneas an trealaimh, go háirithe roinnt innealra ardchruinneas. Agus cad iad na fachtóirí a mhéadóidh teocht an scriú liathróid?
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.
Molann HIWIN gurb é an réamh-ualach meánach agus trom ná 8 faoin gcéad den ualach dinimiciúil; is é an réamhualach meánach 6 faoin gcéad go 8 faoin gcéad; is é an réamh-ualach meánach agus éadrom 4 faoin gcéad go 6 faoin gcéad; tá an réamh-ualach solais faoi bhun 4 faoin gcéad, agus níor chóir go mbeadh an réamh-ualach is troime níos mó ná 10 faoin gcéad An t-ualach dinimiciúil chun an saolré is fearr agus an éifeacht ardú teochta níos ísle a fháil.
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) nuair a bhíonn an ola bhealaithe 40céime; Déantar cúiteamh trí réamh-tharraingt; agus is é an luach T diúltach atá léirithe ar an líníocht spriocluach an chúitimh roimh-. Déanfaidh an iomarca pretension an imthacaí tacaíochta a dhó, mar sin molann HIWIN go n-úsáidfí luach pretension níos lú ná 5céime, ach níl sé oiriúnach le haghaidh pretension má tá trastomhas an scriú níos mó ná 50mm; tá fórsa mór pretension ag teastáil le trastomhas scriú mór, rud a fhágann go bhfuil tacaíocht róthéite agus dóite amach an t-imthaca.
