Abstract
The invention relates to a limit locking nut and a limit locking device. The limit locking nut comprises a nut which can be screwed into a shaft, wherein at least two grooves into which limit plates can be inserted are arranged at one outer side of the nut, and each limit plate passes through the side wall of the nut on which at least one bolt is fixed. The limit locking device is characterized in that the nut is screwed into a preset position of the shaft, and the limit plate is radially inserted from the groove at the outer side of the nut and is contacted with a shoulder; and the limit plate is fixed on the nut by the bolt or the bolt along with a gasket. The limit locking device has the characteristics of simpler processing and assembly, more reliable locking and the like, and can be applied in mechanical equipment requiring high reliability.
Description
Technical field
What the present invention relates to is a kind of spacing locking nut and spacing locking device that is used for axle, belongs to the mechanical position limitation locking mechanism.
Background technique
The spacing locking device that is used for axle at present; What generally adopt is standard round nut as shown in Figure 1; The standard round nut is made up of round nut 11 and lock washer 12; Circle stop tongue is embedded in the groove 13 on the axle in the lock washer, and cylindrical stop tongue is embedded in the breach 14 of round nut cylindrical, thereby accomplishes the locking to round nut.This round nut locking and positioning is inaccurate, because the stop tongue on breach on the round nut cylindrical and the lock washer cylindrical has differential seat angle usually, could lock when having only both angles in full accord, so there is tight situation of when pine time.In addition, this round nut work and unreliable, when round nut stressed big, the stop tongue of circle has the risk of being cut off in the lock washer.
Summary of the invention
The objective of the invention is to overcome the deficiency that existing technology exists, and provide a kind of processing and assembling simpler, lock more reliably, can be applicable to spacing locking nut and spacing locking device in the higher machinery of reliability requirement.
The objective of the invention is to accomplish through following technological scheme; Described spacing locking nut; It includes the nut that can screw on; The outside of the relative screw-in direction of this nut is provided with the radial groove that at least two difference can supply limiting board to insert, and said each limiting board all through at least one bolt on the sidewall of nut.
Described groove is four, and symmetry is uniformly distributed with, and said each limiting board all is fixed on the sidewall of nut through a bolt and packing ring.
A kind of spacing locking device that mainly constitutes by above-mentioned spacing locking nut; This device is on the precalculated position on the axle, to screw in said nut is arranged; In the radial groove that is provided with on the outside of the relative screw-in direction of this nut; Be inserted with the limiting board that contacts with the shaft shoulder of said axle, and said limiting board is fixed on the said nut with packing ring through axial bolt or bolt.
Spacing stripped nut of the present invention is a kind of novel stripped nut that principle is different from the standard round nut of locking; It compared with prior art has following technique effect: the one, and it is more accurate to locate, and installs very simple and conveniently, and limiting board locking does not need the angle contraposition when installing, and can adapt to the circumferencial direction unspecified angle; Owing to need not adjust angle during the location,, install also more simple and convenient so axially locating is more accurate; The 2nd, functional reliability is very high, and the thickness of spacing stripped nut limiting board is bigger than the thickness of standard round nut lock washer stop tongue, and its one-tenth-value thickness 1/10 can be adjusted according to design demand; Simultaneously, limiting board quantity is 4, and circle stop tongue has only one usually in the standard round nut lock washer, and spacing stripped nut peformance margin is several times of standard round nut.
Description of drawings
Fig. 1 is the structural representation of existing standard round nut.
Fig. 2 is a structural representation of the present invention.
Fig. 3 is that the side of Fig. 1 is shown structural representation.
Embodiment
To combine below accompanying drawing to the present invention make detailed introduction: Fig. 2, shown in 3; Spacing locking nut of the present invention; It includes the nut 22 that can screw on one 21; One outside of this nut 22 is provided with the groove 24 that at least two difference can supply limiting board 23 to insert, and said each limiting board 23 all is fixed on the sidewall of nut 22 through at least one bolt 25.
Fig. 2, the nut shown in 3 22 are round nut; One outside of this round nut is provided with groove 24 that four symmetries are uniformly distributed with, that supply limiting board 23 radially to insert respectively, said each limiting board 23 all are fixed on the sidewall of nut 22 with packing ring 26 through a bolt 25.
Spacing locking device of the present invention; This device is at screw-in on the precalculated position of an axle 21 described nut 22 to be arranged; Described limiting board 23 radially inserts from the groove 24 of nut arranged outside and contacts with the shaft shoulder 27, and said limiting board 23 usefulness bolts 25 or bolt 25 are fixed on the said nut 22 with packing ring 26.
Spacing stripped nut of the present invention is made up of round nut, limiting board, bolt and packing ring; During work; Tighten round nut earlier to the precalculated position, again limiting board is radially inserted along the groove on the round nut, contact with the shaft shoulder up to limiting board; At last bolt and packing ring are tightened, connect limiting board and round nut and get final product in one.Because limiting board directly peaks on the shaft shoulder gap that limiting board does not all shrink back with round nut, accurate positioning, reliable lock.
Claims (3)
1. spacing locking nut; It includes the nut that can screw on; The outside that it is characterized in that the relative screw-in direction of this nut is provided with the radial groove that at least two difference can supply limiting board to insert, and said each limiting board all through at least one bolt on the sidewall of nut.
2. spacing locking nut according to claim 1 is characterized in that described groove is four, and symmetry is uniformly distributed with, and said each limiting board all is fixed on the sidewall of nut through a bolt and packing ring.
3. spacing locking device that mainly constitutes by claim 1 or 2 said spacing locking nuts; This device is on the precalculated position on the axle, to screw in described nut is arranged; In the radial groove that is provided with on the outside of the relative screw-in direction of this nut; Be inserted with the limiting board that contacts with the shaft shoulder of said axle, and said limiting board is fixed on the said nut with packing ring through axial bolt or bolt.
