Description

Technical Field

[0001] The utility model relates to the technical field of reamed hole bolt accessories, in particular to a reamed hole nut. Background Art

[0002] The front thread of the reamed hole bolt plays a connecting role, and the rear threadless part plays a positioning role. Ordinary bolts can withstand lateral and axial loads, but the method of bearing lateral loads mainly relies on the friction caused by the preload torque, while the reamed hole bolt can also withstand lateral and axial loads. The method of bearing lateral loads relies on the shear strength of the bolt itself. Its lateral bearing capacity is much higher than that of ordinary bolts, while its axial bearing capacity is the same as that of ordinary bolts. The basic size between the diameter of the screw part of the ordinary bolt and its hole is generally different (the hole size is generally 0.5 to 1 mm larger than the bolt size), so it cannot be called a match. It relies on the preload force of the bolt to prevent the relative sliding and movement of the connected parts. When there is relative sliding between the connected parts, the preload force is converted into friction to prevent them from moving, so a larger preload force is required. The reamed hole bolt connection, the diameter of the screw part is the same as the basic size of the hole, which is a transition fit (not a clearance fit). When there is relative sliding between the connected parts, the shear resistance of the bolt itself is relied on to prevent them from moving, so only a smaller preload force is required. Reamed hole bolts are used in structures that use friction to transmit force (transmit force by the shape of the part) under vibration load conditions.

[0003] The structure of the nut of the existing reamed hole bolt is basically the same as that of the ordinary nut, resulting in the axial load capacity of the reamed hole bolt being the same as that of the ordinary bolt. When parts with large vibration load conditions are connected, the internal thread of the reamed hole nut may be damaged, resulting in a shorter overall service life of the reamed hole nut.

[0004] For this purpose, we propose a reaming hole nut. Utility Model Content
