Abstract
The utility model provides a novel locking nut, includes the nut body, the nut body is the hexagonal type, be equipped with the notch on the outer circumference of nut body, its characterized in that: the processing of nut hole inner wall has twice to warp the groove, is inside groove and water jacket respectively, interior groove width 2mm, outer groove width 2.5mm, groove depth 7.5mm-8.5mm, locking nut's outer periphery is the face through mid frequency quenching, and the mid frequency quenching available depth is 1-10mm. Adjustable screw line size, appearance are passed through in this practicality, and nut non -deformable tautness is good, and it is good to dismantle the resilience original state, the repetitious usage of being convenient for, through carry out appropriate mid frequency quenching on locking nut's face, reach the locking nut long -life to use.
Description
Technical field
The utility model belongs to the manufacture field of nut, is specifically related to a kind of locking nut.
Background technique
Locking nut is a kind of conventional nut being widely used in machinery industry; In the operation of some machinery equipment, as helical-lobe compressor, higher to the requirement of environment, therefore higher requirement is proposed for locking nut, to be applicable to work under bad environment, the environment of the high moment of torsion that easily gets loose, needs.
Summary of the invention
The purpose of this utility model is to provide a kind of locking nut, and it possesses reliable nut lock sigma compactness.
The technical solution of the utility model is: a kind of locking nut, comprises nut body, and nut body is hexangle type, and the excircle of described nut body is provided with notch; It is characterized in that: nut bore inwall is processed with twice distortion groove, is respectively inside groove and water jacket, described interior groove width 2mm, outer groove width 2.5mm, groove depth 7.5mm ~ 8.5mm; The outer peripheral surface of described locking nut is through mid frequency induction hardening face, and mid frequency induction hardening effective depth is 1 ~ 10mm.
Further, be through mid frequency induction hardening face outside described locking nut, mid frequency induction hardening effective depth is 2 ~ 5mm.
Beneficial effect: the utility model is by adjustment thread size, external form, and the not yielding tautness of nut is good, and dismounting resilience original state is good, is convenient to repeatedly use; By carrying out suitable mid frequency induction hardening on the face of locking nut, reach the use of locking nut long lifetime.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1, inside groove, 2, water jacket, 3, notch, 4, outer peripheral surface.
Embodiment
