Service HotlineThe retaining ring is an industrial accessory that can function as support, buffering, braking, height adjustment and angle adjustment. The inner diameter of the retaining ring for the shaft is slightly smaller than the diameter of the assembly shaft. When the retaining ring for the hole is selected, the outer diameter of the retaining ring is slightly larger than the diameter of the assembly circular hole. The retaining ring mainly plays the role of axial fixation. The surface plus the retaining ring is fixed with a high degree of centering.
The first is to use two identical nuts to screw on the same bolt, and add a tightening torque between the two nuts to make the bolt connection reliable. The second is a special anti-loosening nut, which needs to be used together with a kind of anti-loosening washer. The special lock nut is not a hexagonal nut, but a medium round nut. There are 3, 4, 6 or 8 notches on the circumference of the nut (depending on the size of the nut and the product series of the manufacturer). Several notches are both the focal point of the tightening tool and the snap-in of the lock washer bayonet. The third type is to drill through threaded holes from the outer surface of the nut to the inner thread surface (usually 2, which are distributed at 90 on the outer surface), which are used to screw in small-diameter countersunk head screws. The purpose is to give the thread Apply a centripetal force to prevent the locknut from loosening. The better quality lock nut sold on the market is inlaid with a small copper block that is consistent with the thread of the lock nut on the inner surface of the nut to prevent the radial jacking screw from directly contacting the locked thread and damaging the latter. . This kind of lock nut is gradually applied in the shaft end locking of rotating motion parts, such as the anti-looseness of the bearing at the mounting end of the ball screw. The fourth type of lock nut is composed of two parts, each part has staggered cams. Since the slope angle of the internal wedge design is greater than the nut angle of the bolt, this combination is tightly integrated into a whole. When vibration occurs When the lock nut is moved, the raised parts of the lock nut move with each other to generate lifting tension, so as to achieve a perfect anti-loosening effect. The fifth is structural anti-loosening. Through the design and improvement of the threaded structure, a self-locking function is obtained without the help of other external factors. Therefore, its applicability is wider than the above methods, and the requirements for the environment are also relatively high. Low. There are many types of lock nuts, such as nylon nuts and flange nuts. In short, this kind of lock nuts plays a role in preventing loosening. Twist the nut onto the screw, screw, bolt, etc., so that it will not come loose. So that they can be actively connected together, so that it is firm, and the stability can reach a high degree.
Lock nut is a kind of nut widely used in machinery and other industries. Its working principle is self-locking by the friction between the nut and the bolt. However, the reliability of this self-locking is reduced under dynamic loads. In some important occasions, we will take some anti-loosening measures to ensure the reliability of the nut locking.
self-locking screw comprises a screw main body, a metal screw head is arranged on the upper part of the screw main body, a thread is arranged in the middle part of the screw main body, an interference groove is arranged on both sides of the upper part of the screw main body, and the line of the interference groove is arranged. The included angle is 280-365° with the horizontal line. The bottom of the screw body is provided with an elastic chuck, and the elastic chuck includes an optical axis and a conical head. Guangdong Yueluo Hardware Industry Co., Ltd. Guangdong Yueluo Hardware Industry Co., Ltd. adopts the design of elastic collet, and the screw is provided with threaded segments and interference grooves, so that during the screwing process, the interference groove of the optical axis between the two threaded segments is formed along the screw. The axial elastic force achieves the effect of reliable self-locking, which is easy to use and has high tuning efficiency.
In order to meet the requirements of anti-loosening bolts of parts with small surface hardness such as plastic parts, Yueluo provides a spring washer and the installation structure of the spring washer, which can effectively reduce the damage of the spring washer to the surface of the parts. And meet the anti-loosening effect of the spring washer. The technical solution provided by Yueluo is a spring washer, which includes a washer body with at least two raised claws on the washer body
