Description
Technical field
The utility model relates to a kind of automobile gearbox locking nut.
Background technology
Locking nut is a kind of common nut being widely used in the industries such as machinery.
The operation principle of locking nut is to use the frictional force between nuts and bolt to carry out self-locking, but in dynamic loading
In the reliability of this self-locking will reduce.The anti-loosing effect quality of locking nut depends primarily on nut and engages screw thread with bolt
Between interaction force.
Utility model content
The utility model purpose is to provide a kind of automobile gearbox novel lock for the deficiency existing for prior art
The technical scheme of jack panel, is possible not only to tentatively lock, and plays positioning action, and is made by the tensioning of locking spring
With so that locking nut will not unclamp easily, plays the effect of secondary locking, substantially increases the security of locking nut, with
When convenient install and dismounting, it is simple to maintenance.
In order to solve above-mentioned technical problem, the utility model adopts the following technical scheme that
A kind of automobile gearbox locking nut, including nut body and laminating lid, laminating lid is fixedly connected on close
On the nut body of gearbox side, it is characterised in that: also include retaining ring, in nut body, be provided with cannelure, retaining ring
Matching with cannelure, retaining ring props up laminating lid by locking spring；By arranging retaining ring in nut body, and
Between retaining ring and laminating lid, locking spring is set, the locking effect of locking nut can be effectively improved, and of the prior art
Locking nut is compared has more preferable stability and intensity, due to the tension of locking spring so that locking nut will not be light
Easily unclamp, substantially increase the security of locking nut, improve the quality of gearbox, facilitate simultaneously and install and dismounting, it is simple to
Maintenance.
Further, laminating lid and the junction of nut body are provided with circular arc chamfering, and circular arc chamfering not only contributes to remove
Burr, makes locking nut more attractive, can effectively reduce the stress concentration that laminating covers simultaneously, improve the strong of whole locking nut
Degree, makes assembling be easier to.
Further, the medial surface of retaining ring is provided with the first internal thread, the lateral surface of retaining ring is provided with external screw thread,
Being provided with thread groove in cannelure, external screw thread matches with thread groove, and the first internal thread can play the effect of secondary locking, outward
Screw thread and thread groove can improve the bonding strength of retaining ring and nut body, improve the overall performance of locking nut.
Further, the medial surface of laminating lid is provided with the second internal thread, the second internal thread can play preliminary locking and
The effect of positioning.
The utility model, owing to have employed technique scheme, has the advantages that
1st, by arranging retaining ring in nut body, and locking spring is set between retaining ring and laminating lid, can
To effectively improve the locking effect of locking nut, there is compared with locking nut of the prior art more preferable stability and strong
Degree；
2nd, due to the tension of locking spring so that locking nut will not unclamp easily, substantially increases locking nut
Security, improve the quality of gearbox, facilitate simultaneously and install and dismounting, it is simple to maintenance.
The utility model simple in construction, practical, it is possible not only to tentatively lock, play positioning action, Er Qietong
Cross the tension of locking spring so that locking nut will not unclamp easily, play the effect of secondary locking, substantially increase lock
The security of jack panel, facilitates simultaneously and installs and dismounting, it is simple to maintenance.

Detailed description of the invention
As shown in Figures 1 to 4, for a kind of automobile gearbox locking nut of the utility model, including nut body 1 He
Laminating lid 2, lid 2 of fitting is fixedly connected on the nut bodies 1 of gearbox side, the connection of laminating lid 2 and nut body 1
Place is provided with circular arc chamfering 4, and circular arc chamfering 4 not only contributes to flash removed, makes locking nut more attractive, can effectively subtract simultaneously
Stress on little laminating lid 2 is concentrated, and improves the intensity of whole locking nut, makes assembling be easier to.
Also include retaining ring 3, the medial surface of retaining ring 3 is provided with the first internal thread 7, the lateral surface of retaining ring 3 sets
Being equipped with external screw thread 8, being provided with thread groove in cannelure 5, external screw thread 8 and thread groove match, and the first internal thread 7 can play two
The effect of secondary locking, external screw thread 8 and thread groove can improve the bonding strength of retaining ring 3 and nut body 1, improve locking nut
Overall performance.
Being provided with cannelure 5 in nut body 1, retaining ring 3 matches with cannelure 5, and retaining ring 3 passes through locking spring 6
Prop up laminating lid 2, the medial surface of laminating lid 2 be provided with the second internal thread 9, the second internal thread 9 can play preliminary locking and
The effect of positioning；By arranging retaining ring 3 in nut body 1, and locking bullet is set between retaining ring 3 and laminating lid 2
Spring 6, can effectively improve the locking effect of locking nut, has more preferable stability compared with locking nut of the prior art
And intensity, due to the tension of locking spring 6 so that locking nut will not unclamp easily, substantially increases locking nut
Security, improves the quality of gearbox, facilitates simultaneously and install and dismounting, it is simple to maintenance.
These are only specific embodiment of the utility model, but technical characteristic of the present utility model is not limited thereto.Appoint
How based on the utility model, for realizing essentially identical technique effect, done ground simple change, equivalent or repair
