Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-3, a large-scale self-locking nut for rotary equipment, including nut body 1, 1 top of nut body has locking end 2, and 1 bottom of nut body has locking dish 3, set up the thread groove 7 that is linked together in nut body 1 and the locking dish 3, ring shape caulking groove 9 is seted up at 2 tops of locking end, and installs nylon ring 8 in ring shape caulking groove 9, 2 both sides of locking end are all through screw thread installation fastening screw 4, and two fastening screw 4 one end is located nylon ring 8 both sides respectively, ring shape caulking groove 9 top welding stainless steel locking ring 6.
And screwing screws 5 are arranged on two sides of the top of the locking disc 3 through threads.
In this embodiment, as shown in fig. 1 and 2, when the nut body 1 is screwed on a bolt or a screw, a person can screw the screw 5, so that the nut body 1 generates a reverse thrust, thereby improving the locking degree of the nut body 1 on the bolt or the screw.
The bottom of the locking disc 3 is provided with arc-shaped positioning teeth 10, and the arc-shaped positioning teeth 10 are specifically provided with two or more groups.
In this embodiment, as shown in fig. 1 and 3, the locking disk 3 and the bottom arc-shaped positioning teeth 10 are arranged, so that an elastic pad is not required to be arranged when the nut body 1 is locked, the locking disk 3 does not displace in the locking process, the locking effect is good, and the nut body 1 is prevented from being loosened from a bolt or a screw due to external force.
