Nord-Lock Group Nord-Lock Продукты Оригинальные шайбы Техническое руководство
Компания Nord-Lock разработала технологию стопорно-клиновой фиксации, обеспечивающую надежность болтовых соединений даже в условиях сильной вибрации и динамических нагрузок. Самопроизвольное ослабление соединения нашей продукции полностью исключено благодаря клиновой фиксации, возникающей под головкой болта и гайкой.

Joint Guide

Nord-Lock_Joint-Guide_Washer_Tapped-Holes.jpg

Tapped holes
Nord-Lock washers safely lock the bolt against the underlying surface.

Counterbores
The outer diameter of regular Nord-Lock washers is designed for counterbore holes according to DIN 974, i.e. the washers fit under the head of standard bolts.

Through-holes
As for all locking washers, through-holes require two pairs of Nord-Lock washers – one pair for securing the bolt and a second pair for securing the nut. Turn both fasteners in order to close the cams on both washer pairs before tightening to minimize settlements. Keep the nut secure while tightening the bolt.

Stud bolts
Nord-Lock washers safely lock the nut on stud bolts and eliminate the need for adhesives.

Applications with large / slotted holes or soft underlying surfaces
To optimize the load distribution for applications with large / slotted holes or with soft underlying surface, use a flanged nut / bolt together with Nord-Lock “SP” washers with enlarged outer diameter.

Designs where Nord-Lock washers are not recommended

  • Mating surfaces that are not locked in place (see left figure)
  • Mating surfaces harder than the washers
  • Very soft mating surface, e.g. wood, plastic
  • Applications with extremely large settlements
  • Non-preloaded joints
