Beschreibung
Zusammenfassung:	The invention relates to a sealed screw-rod-type linear module comprising a screw rod, a ball screw rod nut assembly, a cylindrical screw rod cover and a transmission device. At least one end of a nutis provided with at least one inner permanent magnet ring, the inner permanent magnet rings and the nut are divided through magnetism blocking pieces, and the inner permanent magnet rings and the magnetism blocking pieces are coaxial with the screw rod and do not mutually interfere. The screw rod and the ball screw rod nut assembly are arranged inside the screw rod cover. The transmission devicecomprises a transmission platform, the transmission platform is arranged on the outer side of the screw rod cover in a sleeving mode and slidably connected with the screw rod cover, unclosed outer permanent magnet rings are arranged in the platform, and the outer permanent magnet rings and the inner permanent magnet rings are opposite in position and coaxial. The sealed screw-rod-type linear module has the beneficial effec
