The existing adjusting screw is generally composed of a screw and a nut on the top of the screw. The screw is driven to rotate by means of a screwdriver, and then the screw is driven to rotate. In and out, adjusting other objects connected to it and changing position accordingly.
Anti-loose washers are also known as anti-loose washers, self-locking washers, self-locking gaskets, DIN25201 anti-loose washers, double-stack self-locking anti-loose washers, double-stack wedge-type anti-loose washers, etc.
The retaining ring is a ring-shaped body with an opening, and the traditional processing method is stamping. That is, a plate-shaped material is selected and punched out on the plate-shaped material (a circular body, and then the middle of the circular body is punched to form a ring-shaped ring body.) The punched material in the middle cannot be used again. This results in a waste of material.
Gaskets are mechanical components used for cooperation between two objects, which play a role in preventing pressure, corrosion and leakage of pipes from natural thermal expansion and contraction between two objects. By using the gasket in conjunction with the bolt and nut, the gasket can increase the contact area between the bolt and nut and the metal parts, and play the role of buffering and shock absorption to prevent the thread from loosening.
In the process of driving the car, it is inevitable to use the brake frequently, which will cause the gap between the brake drum and the friction pad of the car to become larger. Therefore, it needs to be adjusted in time, otherwise, the hidden danger of unsafe driving will be buried due to the excessive braking distance and the out-of-round brake drum. Therefore, motor vehicles must be equipped with automatic adjustment arms. In the existing automatic adjustment arm, the worm inside the housing is limited by the spring pad, the spring and the spring cover, and the end face of the spring pad is directly in contact with the worm, and the rotation of the worm is inflexible due to frictional resistance during rotation.
