Description
Technical Field
The utility model relates to a wind power generation technical field especially relates to a large-scale easy installation self-locking nut.
Background
The nut is used as a component part of a common connector and plays a great role in fastening and connecting parts of the wind generating set. When the wind turbine generator is connected and installed and fixed on a shafting, a certain proportion of installation modes for fastening parts by using a large-scale unconventional thread pair exist, such as the fastening of a main bearing and the like. With the upsizing of the wind turbine generator, the diameters of parts such as a main shaft and the like are gradually increased, the bearing mounted on the main shaft is correspondingly increased, and the upsizing of a nut for fastening the inner ring of the bearing is more obvious. The problem that looseness prevention of a large nut after installation becomes that no avoidance can be avoided in the installation of parts of the wind turbine generator is solved.
SUMMERY OF THE UTILITY MODEL
The utility model discloses solve the problem that above-mentioned prior art exists, provide a large-scale easy installation auto-lock nut, solve two kinds of key characteristics of easy installation and auto-lock of large-scale nut.
The utility model provides a technical scheme that its technical problem adopted: the large-scale easy-to-install self-locking nut comprises a nut body, wherein the nut body is arranged in an annular state, a group of simple installation rods are arranged on the side face of the nut body, a group of cutting grooves are formed in the side face of the nut body, the cutting grooves and the simple installation rods are arranged in a staggered state, the cutting grooves and the upper end of the nut body are arranged in a parallel state, a locking bolt is arranged on a vertical non-connection face of each cutting groove, and the locking bolt is arranged on the nut body.
The number of the simple mounting rods is four.
The number of the cutting grooves is three.
The utility model discloses profitable effect is: the utility model discloses a large-scale easy installation self-locking nut, it is rational in infrastructure, possess following advantage:
firstly, the processing is simple, the strength is good, and the structure is reliable;
secondly, the fastening and the dismounting can be realized through a simple mounting rod carried by the self, other tools are not needed, and the limitation of the mounting environment is avoided;
thirdly, the mounting and dismounting operations are simple;
and fourthly, self-locking and unlocking adjustment are carried out by screwing the locking bolt, self-locking and unlocking are convenient, and repeated use can be realized.

Description of reference numerals: the nut body 1, simply install pole 2, cut groove 3, lock bolt 4.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
with reference to the accompanying drawings: this large-scale easy installation self-locking nut in this embodiment, including nut body 1, nut body 1 is the setting of annular state, is provided with a set of simple and easy installation pole 2 on nut body 1's the side, it has a set of cut groove 3 to open on nut body 1's the side, cut and be the setting of staggered state between groove 3 and the simple and easy installation pole 2, cut the upper end of groove 3 and nut body 1 and personally submit parallel state setting, cut and install locking bolt 4 on the 3 perpendicular non-hookup faces in groove, locking bolt 4 sets up on nut body 1.
The number of the simple mounting rods 2 is four.
The number of the cutting grooves 3 is three.
A large self-locking nut easy to install comprises a nut body 1, a locking bolt 4, a simple installation rod 2 and a cutting groove 3. Wherein the simple mounting rod 2 will be removed after the nut is mounted in place.
Further, the nut body 1 is designed to have a ring structure, the ring-shaped internal configuration thread is matched with the thread of the connected part, and the thickness of the ring structure is selected according to the thread pitch of the internal thread, and usually the thread pitch of the internal thread is not less than ten times. The annular structure is evenly distributed with three cutting grooves 3 along the circumferential direction. The cutting groove 3 is parallel to the end surface of the nut, the distance between the cutting groove 3 and the non-coupling surface of the nut is about 1/3 total height, and 2 hole sites are arranged in the area of each cutting groove 3 and are perpendicular to the non-coupling surface to be coupled with the locking bolt 4. The upper area of the cutting groove from the non-connecting surface is a round through hole, and the area below the lower cutting groove corresponding to the cutting groove is a threaded hole. The thickness position of the ring-shaped structure outer ring 1/2 is provided with six uniformly distributed M20 thread mounting holes which are not smaller than the M20 thread mounting holes and are connected with the simple mounting rod, the thread mounting holes are staggered with the cutting grooves, and the local area of the surface of the nut outer ring where the threaded holes are located needs to be reamed.
Still further, the locking bolt 4 adopts six high-strength bolts not less than M20, and the length of the bolts is not less than the thickness of the 2/3 annular structure.
Furthermore, simple installation pole 2, quantity is four, adopts the round steel processing to form, and the external screw thread cylinder head is established to the installation pole front end, and thread specification and length configure with ring structure outer lane screw thread mounting hole, and the external screw thread cylinder head adopts right angle step fillet transition with rear end installation pole, and the step face need can laminate with the screw thread mounting hole spot facing district of nut body. The tail part of the mounting rod is sleeved with a rubber handle. The simple installation rod 2 will be removed after the installation is completed.
The technical conception of the utility model is as follows: the installation of nut adopts external long connecting rod to revolve to twist the type structure, utilizes the length of adjusting the installation pole to adjust the arm of force to reach the purpose that the moment of torsion was revolved in the adjustment and realize the installation of nut. The self-locking of the nut adopts a bolt to compress the upper nut area and the lower nut area of the cutting groove, so that the thread teeth in the cutting groove area of the nut deform, and the purpose of locking the nut with the threads of the connected part is achieved through extrusion.
While the invention has been shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the scope of the appended claims.
