Abstract
The utility model relates to a nut, in particular to a simple detachable self-locking nut. The utility model solves the problems of difficulty in disassembling a sealing ring and complex process when a motor bearing is axially fastened. The simple detachable self-locking nut comprises a nut body and a screw hole running through the nut body. The outer lateral surface of the nut body is provided with a deformed gap vertical to the axis of the screw hole. The end face of the nut body is provided with a backing-up screw mounting hole running through the deformed gap. Based on a completely new structure, the utility model effectively solves the problems of difficulty in disassembling the sealing ring and complex process when the motor bearing is axially fastened. The simple detachable self-locking nut is very convenient to manufacture, assemble and disassemble, is suitable for axially fastening the bearing in a motor and is particularly suitable for axially fastening the bearing in a wind driven generator.
Description
Technical field
The utility model relates to nut, specifically is a kind of simple and easy detachable self locking type locking nut.
Background technique
In motor, axially fastening mainly of bearing realize through the interference fit between the Feng Huanyu rotating shaft, and interference fit envelope ring dismounting difficulty when causing envelope ring assembling difficulty and maintenance bearing easily.In order to overcome the difficulty that Feng Huanyu rotating shaft interference fit is brought, need using Spielpassung instead between the Feng Huanyu rotating shaft, adopt nut that envelope ring and bearing are axially fastened then.But because the restriction of conventional nut self structure; When adopting conventional nut to axially fasten; Cooperate with screwed through nut and to realize sealing axially fastening of ring, bearing, then together or adopt and stick up the shape packing ring and carry out locking rotating shaft, nut and envelope loops welded.Adopt welding to carry out locking making and form on-dismountable the connection between nut and rotating shaft, the envelope ring, thereby envelope ring dismounting difficulty when causing keeping in repair bearing is stuck up the shape packing ring and carried out also needing in rotating shaft, process axial anti-rotation groove, thereby causing complex procedures when locking and adopt.Based on this, be necessary to invent a kind of brand-new nut that motor bearings is axially fastened that is applicable to, the problem of envelope ring dismounting difficulty, complex procedures when motor bearings being axially fastened with solution.
Summary of the invention
The problem of envelope ring dismounting difficulty, complex procedures provided a kind of simple and easy detachable self locking type locking nut when the utility model axially fastened motor bearings in order to solve.
The utility model is to adopt following technological scheme to realize: simple and easy detachable self locking type locking nut comprises nut body and the screw that runs through nut body; The outer side surface of nut body has the distortion slit with the screw axis normal, and the end face of nut body has and runs through the backing-up screw mounting hole that is out of shape the slit.
During use, in rotating shaft, process screw thread.Concrete using process is following: when the motor middle (center) bearing is axially fastened, adopt Spielpassung between the Feng Huanyu rotating shaft.Nut body is screwed in the rotating shaft, and in the backing-up screw mounting hole, is screwed into backing-up screw, the distortion slit is deformed, and then make nut body and backing-up screw interlocking, realize axially fastening of envelope ring, bearing thus.Tighten backing-up screw, make the screw thread of screw and the screw thread in the rotating shaft push the generation friction mutually, can reach locking purpose.Based on said process; Compare with conventional nut; Adopt the described simple and easy detachable self locking type locking nut of the utility model that motor bearings is axially fastened and have following advantage: for removably connecting, made things convenient for the dismounting of envelope ring between one, nut and rotating shaft, the envelope ring.Two, need not the axial anti-rotation groove of processing in rotating shaft, simplified operation.In sum, the described simple and easy detachable self locking type locking nut of the utility model is based on brand new, efficiently solves the problem of envelope ring dismounting difficulty, complex procedures when motor bearings axially fastened.
Further, the outer side surface of nut body is provided with axial notch.Can bolt body be screwed in the rotating shaft quickly and easily through axial notch, improve working efficiency thus.
The utility model is based on brand-new structure; Efficiently solve the problem of envelope ring dismounting difficulty, complex procedures when motor bearings axially fastened; Its manufacturing, assembling, dismounting are all very convenient; Be applicable to axially fastening of motor middle (center) bearing, be particularly useful for axially fastening of wind-driven generator middle (center) bearing.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the right elevation of Fig. 1.
Fig. 3 is the user mode reference drawing of the utility model.
Among the figure: the 1-nut body, the 2-screw, 3-is out of shape the slit, 4-backing-up screw mounting hole, the 5-axial notch, the 6-bearing, 7-seals ring, the 8-rotating shaft.
Embodiment
Simple and easy detachable self locking type locking nut comprises nut body 1 and the screw 2 that runs through nut body 1; The outer side surface of nut body 1 has the distortion slit 3 with screw 2 axis normal, and the end face of nut body 1 has and runs through the backing-up screw mounting hole 4 that is out of shape slit 3;
The outer side surface of nut body 1 is provided with axial notch 5;
The number of backing-up screw mounting hole 4 and axial notch 5 is two;
Concrete using process is as shown in Figure 3: when motor middle (center) bearing 6 is axially fastened, adopt Spielpassung between envelope ring 7 and the rotating shaft 8.Nut body 1 is screwed in the rotating shaft 8.Behind fastening nut body in the rotating shaft, in the backing-up screw mounting hole, be screwed into backing-up screw, the distortion slit is deformed, and then make nut body and backing-up screw interlocking, realize axially fastening of envelope ring, bearing thus.Backing-up screw can adopt interior hexagonal backing-up screw.
