Embodiment 1

[0022] The E section and F section at the end of the large-diameter shaft 1 are provided with right-handed threads, the E section is right-handed, and the F section is left-handed. The fixed nut 3 is right-handed and left-handed. The lock nut 5 It is left-handed and right-handed, and the anti-loosening device is composed of a fixed nut 3, a tension screw 4, a push screw 6 and a lock nut 5. The front end of the tension screw 4 has threads, and the rear end has no threads. The rear end of the opening screw 6 is threaded, and the front end is unthreaded. Two blind holes and two internally threaded holes are processed on the circumferential direction of the fixing nut 3. The blind holes and internally threaded holes are arranged crosswise. 2 light through holes and 2 internal thread through holes are processed in the direction, the light through holes and the internal thread through holes are arranged crosswise, the threaded front end of the tension screw 4 passes through the light...

Abstract

The invention discloses a left-handed and right-handed rotation nut locking device for a large-diameter shaft end, which includes a large-diameter shaft lever (1), a clamped body (2) and a locking device, wherein left-handed and right-handed rotation screw threads are arranged at an E section and an F section of an end part of the large-diameter shaft lever (1); the locking device comprises fixing nuts (3), tensioning bolts (4), pushing bolts (6) and locking nuts (5); the fixing nuts (3) are screwed tightly at the E section screw thread; the locking nuts (5) are screwed tightly at the F section screw thread; the distances between the fixing nuts (3) and the locking nuts (5) range from 0.5 mm to 20 mm; and the fixing nuts (3) and the locking nuts (5) are connected by the tensioning bolts (4) and the pushing bolts (6) respectively. The large-diameter shaft end left-handed and right-handed rotation nut locking device is suitable for fastening the large-diameter shaft end.

Description

technical field [0001] The invention relates to an anti-loosening device, in particular to an anti-loosening device for a large-diameter shaft end rotating left and right nuts. Background technique [0002] At present, when the end of a large-diameter shaft needs to be tightened with a nut, the nut is not easy to tighten due to the large diameter of the shaft, and the vibration of the machine during operation will also cause the nut to loosen, which will cause the performance of the machine to change during operation. Poor, or even cause an accident. [0003] In order to prevent the nut from loosening, there will be a special lock nut, but this kind of lock nut must be drilled on the shaft and the nut at the same time, and it must be wrapped with iron wire after assembly, and it cannot be reused; This kind of lock nut is realized by potting glue, and it cannot be reused; [0004] There are also anti-loosening left and right-handed thread combination bolts and nuts. This co...
