Tlhaloso ea Ball Screw

Ball screw ke karolo ea mochini e fetolang motsamao oa ho potoloha hantle hore e be motsamao oa mola ka ho sebelisa libolo tse potolohang lipakeng tsa screw shaft le nut. Maemo a eona a tlase-a khohlang a e etsa hore e sebelisoe haholo mecheng e nepahetseng le lisebelisoa tsa boiketsetso.

Likarolo tsa screw screw ke tse latelang:
• Screw shaft:Karolo ea mantlha e fetisang motsamao oa ho potoloha.
• Ball nut:E na le libolo tse potolohang ho fihlela motsamao o boreleli.
• Libolo:Theola likhoele tsa nut le screw shaft, ho fokotsa khohlano.
• Mokhoa oa ho potoloha hape:E etsa bonnete ba hore libolo li potoloha ka har'a linate, e leng ho nolofalletsang ho khutla{0}motsamao oa mahala.
• Sesebediswa sa Wiper le ho tiisa:E thibela lerole le ditshila hore di se kene, e netefatsa hore e sebetsa ka thelelo nako e telele-.
