Problems solved by technology

The locking and positioning of this kind of round nut is not accurate, because there is usually an angle difference between the notch on the outer circle of the round nut and the stop tongue on the outer circle of the stop washer, and it can only be locked when the two angles are exactly the same, so when there is loose Tight situation
In addition, the work of this round nut is not reliable. When the force of the round nut is large, the stop tongue of the inner circle of the stop washer may be cut off.

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 [0001] The invention relates to a limit lock nut and a limit lock device for a shaft, belonging to a mechanical limit lock mechanism. Background technique [0002] At present, the limit locking device used for the shaft is generally used as follows: figure 1 The standard round nut shown, the standard round nut consists of a round nut 11 and a stop washer 12, the inner stop tongue of the stop washer is embedded in the groove 13 on the shaft, and the outer stop tongue is embedded in the outer circle of the round nut In the notch 14, thereby completing the locking of the round nut. The locking and positioning of this kind of round nut is not accurate, because there is usually an angle difference between the notch on the outer circle of the round nut and the stop tongue on the outer circle of the stop washer, and it can only be locked when the two angles are exactly the same, so when there is loose Tight situation. In addition, the work of this round nut is no...
