I-roller screwsNgokuqhelekileyo ithathelwa ingqalelo uyilo lwe-planethi oluPhezulu, kodwa ukwahluka okuliqela zikhona, kubandakanya ukwahluka, ukuphindaphinda, kunye neenguqulelo eziphakathi. Uyilo ngalunye lubonelela ngeenzuzo ezizodwa ngokubhekisele kwiZakhono zeNtsebenzo (umthwalo, itota, kunye nokuma), kodwa eyona nto iphambili kwi-screeds screw screw kukwenziwa ngokulula kooseto nakwezinye izinto eziphantsi.
Khumbula ukuba umgangathoI-roller screws. Kwi-rolls ye-rolls, imisebenzi yesikhafu kwaye i-nati ingene ngaphakathi okanye ingena ngaphakathi. I-ner ityhubhu ityhubhu ene-id yesazisi endaweni yokuba nje lithuba ngokwaneleyo ukuze lifumane iirollers kunye namakhonkco egini emangalisayo, ubude bokuhamba kwe-nati. Kwaye i-screw shaft-endaweni yokuba ibetha ubude bayo yonke - ifunyenwe ixesha elide ngokwaneleyo ukuba ilingane nobude be-roller.
IngenaRollerSabasebenzi
NgeI-roller screw screw, ubude be-Natime bumisela ukubetha, kwaye inxalenye ye-scread yescrew kuphela kweengqengqele.
So when the screw shaft rotates, instead of the nut and roller translating along the length of the screw, the rollers remain axially stationary on the screw (that is, the rollers and nut do not move along the length of the screw). Ngokwahlukileyo, ukuguqula i-screw shaft ibangela ukuba i-rollers kunye ne-screw ukuba iguqulele kubude be-nase-Nut. Ngenye indlela, isikhafu se-roller esingena-roller sinokusetyenziselwa ukuqhuba i-nati kwaye sigcine isikhafu (kunye ne-rollers) i-axiries eshiyiweyo.
Kuba umsesane wegiya ohlala uhlala ekupheleni kwe-nut ngoku esekupheleni kwenxalenye ye-screw, ububanzi be-nutter bunokwenziwa buncinci kakhulu kunelo yeplanethi ye-screenI-roller screw. While machining threads within a relatively long nut body can be difficult, inverted roller screws require fewer starts than standard planetary roller screws, meaning they can use larger threads, which in turn provides Higher load capacity than standard design.
Inverted roller screws are ideal for pushrod-style actuators, where the pushrod extends and retracts from the actuator housing. And because a large portion of the screw shaft is unthreaded (only the part where the rollers are), the shaft can be customized to fit the actuator design and application requirements. Uyilo olungena ngaphakathi luyenza lula ukuba abavelisi abavelisi baseNqaku leMagnethi kwiI-roller screwI-Nut kwaye uyisebenzise njenge-rotor yendibano yesihlabo esidibeneyo.
