When is the gasket (flat pad, spring pad)
A washer to prevent loosening of bolts. That is, elastic washer, anti loose washer works very simple. It consists of two washers. The outside is embossed with a radial surface, while the inner oblique tooth surface. When assembled, the medial oblique tooth surface relative to the outer radial surface and both ends of the contact surface relief into the occlusal state when the connectors are vibration, and the trend of bolts loosening, only allow two washers inside oblique tooth relative dislocation, resulting in uplift of tension, so as to achieve the 100% locking.
Split washer (spring washer manufacturers generally will call washer "WASER") flat washer flat washer flat washer is generally used in connecting piece is a soft texture, a hard brittle, its main role is to increase the contact area, pressure distribution, to prevent the soft texture of the bad press. The basic function of the spring of the spring washer is to tighten the nut after the nut to a force, increasing the friction between the nut and bolt! Materials for the 65Mn (spring steel), heat treatment hardness of HRC44 ~ 51HRC, through the surface oxidation treatment. Hua, washers, meson is the same Dongdong, the name is different
The part between the connecting piece and the nut. A flat metal ring is generally used to protect the surface of the connecting piece from the nut.
