Service HotlineNuts and bolts are one of the most widely used fasteners in modern mechanical structures. At present, the common metric bolts and nuts are generally trapezoidal in cross-section. The connection between the bolt and the nut is prone to loosening under severe vibration, or even falls off by itself, and the tightening force of the bolt and nut thread is mainly concentrated in the bolt thread and Between the teeth of the first few threads where the threads of the nut are in contact, resulting in loosening of the fastener and sliding pressure of the threads
In the prior art, the screw suction device can be implemented in the following two ways. One is to use a magnet to magnetize the electric bit head, and the electric bit head is used to approach the screw, and the screw is stuck by the electric bit head, so that the function of picking up the screw can be realized; The vacuum generator is used to form a negative pressure in the screw guide groove, and the screw is sucked into the tube to realize the screw pickup. The disadvantage of this solution is that in the process of picking up the screws, the grooves of the screws cannot be aligned, which leads to the deviation or leakage of the screws. The disadvantage of this solution is that the screw with an aspect ratio of less than 1.5 is prone to suction and skew, and the stability is not high. It can be seen that the existing technology still needs to be improved and developed.
The purpose of Yueluo is to provide a brake pad rivet with shrinkage that can not only solve the problem of normal feeding during assembly, but also save the processing cost of the original machining chamfering and reduce the quality risk of the rivet in use. its production method.
Gears, mechanical components with teeth on the rim that can continuously mesh to transmit motion and power, are mechanical parts with teeth that can mesh with each other. The gears used in industry are generally made of steel. The commonly used steels are quenched and tempered steel, hardened steel, carburized and quenched steel and nitrided steel. The strength of cast steel is slightly lower than that of forged steel, and it is often used in Larger-sized gears; gray cast iron has poor mechanical properties and can be used in light-load open gear transmissions; ductile iron can partially replace steel gears; plastic gears are mostly used in places where light loads and low noise are required, and are matched with them The gears are generally made of steel gears with good thermal conductivity.
