Including Tapered Bushing Or Inner And Outer Sleeve For Cylindrical Bushing Patents (Class 267/270)
  • Patent number: 11686340
    Abstract: A device for fitting two components together by a clevis is improved by a seal including a deformable ring subjected to axial compression between one of the cheeks and a mobile washer which is brought closer to the cheek when a bolt passing through the clevis is tightened. This axial compression causes the rod to be clamped by the seal, eliminating all play and giving the assembly good cohesion while at the same time eliminating the transmission of vibration and noise.
