What is the tolerance range of precision screws?
High-strength self-locking nut for boats and bridges, it can convert the friction force into the expansion force between the bolt and the slot nut to achieve excellent self-locking effect. There are two slots on the upper part of the ESL nut. When the nut is tightened on the bolt, the thread of the bolt will be screwed into the slot of the cross section of the nut, and the thread will be gradually locked by the side wall of the nut to achieve the function of self-locking. The exquisite production process can keep the torque type of the locking element consistent, and the products are generally used in railway casting, rail transit, transmission system, mining equipment, highway, military, oil production machinery, automobile industry, public facilities, subway, engine, construction machinery , aerospace, drilling equipment, bridges, generators, agricultural machinery, shipbuilding industry, metallurgical equipment, trains, compressors, medical machinery, signal systems, wind power generation
In the process of completing the adjustment of the position of the object, the nut will move up and down with the entry and exit of the screw, and it cannot make a sound for people to perceive, and it cannot provide people with a position change distance through the action of rotation.
Although this structure can prevent the shaft from rotating radially to a certain extent, it also has some obvious defects: firstly, the positioning block needs to be opened during processing, and secondly, the opening of the positioning block needs to be opened. After the deformation, the contact between the positioning block and the shaft becomes line-to-line contact, so that the contact area between the positioning block and the shaft is reduced, and the force generated to overcome the radial rotation of the shaft is correspondingly changed. less, so there is a risk that the shaft can turn radially.
Compared with the prior art, the beneficial effects of Guangdong Yueluo Hardware Industry Co., Ltd. are as follows: the square nut has a simple structure, strong practicability and good fastening effect, which changes the smooth plane design of the traditional square nut. There are circular protrusions, and strip protrusions and strip grooves are respectively provided at the two circular protrusions to increase the roughness of the contact surface of the nut, thereby effectively increasing the friction between the nut body and the fastener. , to achieve a good tightening effect.
