Description
Technical field
The utility model relates to a kind of locking gear of scyewed joint, especially a kind of Novel double-nut locking mechanism that is applicable to hole usefulness nut.
Background technique
Scyewed joint is the removable connection that utilizes thread part to consist of, and it is simple in structure, and mounting or dismounting are convenient, are widely used in the various machinery.But under shock and vibration or varying load effect, or in the larger situation of high temperature or temperature variation, the pretightening force in the scyewed joint and frictional force can reduce gradually or may instantaneous disappearance, cause connecting and lose efficacy.In a single day scyewed joint lost efficacy, and will have a strong impact on the normal operation of machine, even caused the accident.Therefore, in the design production process of engineering goods, often can guarantee to connect safe and reliable with nut check mechanism.
Modal nut check mechanism be axle with two on nut, by two spanner counter-rotatings, two nuts are pushed mutually, realize powerful locking, what prevent from connecting gets loose.But for the hole nut, because nut is in the hole, can't effectively block first nut by spanner, therefore, common way is directly to rotate second nut, and when two nuts slightly touched, second nut can drive first nut rotation, first is slightly fast for the speed ratio of second nut, and two nuts are realized mutual locking gradually in this course.But in the process that this is locked mutually, second nut drives first nut rotation, and the number of turns of rotation is subjected to the applying frictional force of two nuts, and the frictional force of nut thread and screw screw thread is all relevant, concrete screw the degree of depth and can't hold.To in the very high product of position accuracy demand, because the rotary course of first nut can't accurately be controlled, this nut and tight mechanism just can't satisfy the demand, and can't realize fast the locking of nut for some.

Description of drawings
The structural representation of one preferred implementation of the Novel double-nut locking mechanism that Fig. 1 provides for the utility model.
The structural representation of another preferred implementation of the Novel double-nut locking mechanism that Fig. 2 provides for the utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Please referring to Fig. 1, the structural representation of a preferred implementation of the Novel double-nut locking mechanism that Fig. 1 provides for the utility model.As shown in Figure 1, this mode of execution comprises the first nut 1, the second nut 2, is located at screw 3, screw 4 on the product main body.Wherein, the first nut 1 and the second nut 2 outsides are provided with outside thread, and the diameter of thread of the second nut 2 is greater than the diameter of thread of the first nut 1, and the outside thread opposite direction on the first nut 1 and the second nut 2.The relevant position is provided with the different dual screw thread of diameter on the screw 3, and its hand of spiral is also opposite, is complementary respectively at the first nut 1 and the second nut 2.The second nut 2 is provided with 3 screws 5, and it distributes along even circumferential, and is complementary with 3 screws 4.
Present embodiment realizes the locking of nut in the following way: at first, the first nut 1 is threaded to the degree of depth that needs, then the second nut 2 is screwed, the second nut 2 is threaded to the position near the first nut, need not to be adjacent to, and the precession degree of depth can suitably freely be held.Again 3 screws 4 are screwed in screw 5 until withstand the first nut 1, so far, finished the locking of nut.
When the first nut 1 has the trend of unclamping, it can produce the trend of rotation under the pressure of screw 4, and the strength transmission by screw 4, the second nut 2 is subject to making the power of its rotation, but because the hand of spiral of the hand of spiral of the second nut 2 and the first nut 1 is opposite, this power is not enough so that the second nut 2 rotates, and screw 4 can more fastening withstanding the first nut 1 and stop its rotation under the effect of the second nut 2.
Present embodiment can also be further improved, and is set as follows: the outside thread direction of screw 4 is identical with the outside thread direction of the second nut 2, with the outside thread opposite direction of the first nut 1.
So, the outside thread opposite direction of the second nut 2 and the first nut 1 not only, has the effect that stops 1 rotation of the first nut, the outside thread of screw 4 also with the outside thread opposite direction of the first nut 1, also has the effect that stops 1 rotation of the first nut, the locking of realization nut that can be more fastening prevents that it from getting loose.
Please referring to Fig. 2, the structural representation of another preferred implementation of the Novel double-nut locking mechanism that Fig. 2 provides for the utility model.As shown in Figure 2, this mode of execution comprises the first nut 11, the second nut 12, is located at screw 13, screw 14 on the product main body.The first nut 11 and the second nut 12 are provided with outside thread, and screw 13 is provided with corresponding internal thread, and the second nut 12 is provided with 3 screws 15, and it distributes along even circumferential, and are complementary with 3 screws 14.
Present embodiment realizes the locking of nut in the following way: at first the first nut 11 is threaded to the degree of depth that needs, then the second nut 12 is screwed in, until the second nut 12 approaches or slightly touch the first nut 11,3 screws 14 are revolved such as screw 15 until withstand the first nut 11 again, so far, finished the locking of nut.
When the first nut 11 had the trend of unclamping, under the resistance of the pressure of screw 14 and the second nut 12, the first nut 11 loosening trend were controlled.This mode of execution is reliable and stable, and the protrusive that can effectively prevent the first nut 11 unclamps to unclamp in the hole with nut with the backing type of the second nut 12 have been realized with axle with the identical effect of nut check.
Present embodiment can also be further improved, and is set as follows: the outside thread opposite direction of the outside thread direction of screw 14 and the first nut 11, the second nut 12.
So, because the hand of spiral of the hand of spiral of screw 14 and the first nut 11 is opposite, when the first nut 11 had the trend of unclamping, screw 14 can produce and hinder the resistance that the first nut 11 becomes flexible.Like this, when the first nut 11 produces loosening trend, it not only is subject to the resistance of press machine second nut 12 of screw 14, also can be subject to because the resistance that screw 14 outside threads and the first nut 11 outside thread opposite directions produce, in this case, present embodiment can reach better locking effect.
The above has done detailed description to the preferred embodiment of the utility model by reference to the accompanying drawings, but the utility model is not limited to above-mentioned mode of execution, within the ken that those of ordinary skills possess, can also under the prerequisite that does not break away from the utility model aim, make various variations.
