Eccentric lock nu is also known as heavy load lock nut, this kind of lock nut is characterized bythe composition of two nuts,nuts in eccentric inner and outer cone local contact.Therefore, in addition to the threading tension of a pair of nuts, there is an eccentric wedge tension.The applied torque makes the conical surface of the two nuts contact each other more tightly, and the wedge tension will be greater.As long as the locking force is sufficient, one-time locking can be realized and never loose (the so-called "bite death" phenomenon);The friction Angle between the two eccentric nuts is much smaller than the standard self-locking Angle,which makes the self-locking reliable.
Product characteristics
Simple structure, convenient and practical,can improve the installation efficiency and installation effect of ecentriclock nut.
Keyway without machining shaft
Improve rotational balance of shaft
