Description
Technical Field
The utility model relates to the technical field of engineering machinery shaft head locking, in particular to a shaft head single nut locking mechanism.
Background
The double lock nuts are matched with the lock washers to realize locking in the engineering machinery drive axle head, and the locking mechanism is reliable and has some problems: 1. the double lock nut mechanism has the problems of complicated installation and disassembly work and inconvenient maintenance; 2. the double-locking axial dimension is longer, a certain dimension requirement exists for space layout, and the problem of difficult layout often exists for a narrow forklift drive axle.
Disclosure of Invention
The present utility model aims to solve at least one of the technical problems in the related art to some extent. Therefore, one purpose of the utility model is to provide a single-nut locking mechanism of a shaft head, which can effectively avoid the problem caused by loosening of locking nuts and realize the locking layout of a driving axle in a smaller space.
The single-nut locking mechanism for the shaft head comprises a shaft head, wherein a locking nut is arranged on the surface thread of the shaft head, a fixing bolt is arranged on the end surface thread of the locking nut, and a plurality of circular grooves for being in butt joint with the fixing bolt are formed in the surface of the shaft head.
Preferably, the surface of the shaft head is provided with external threads for being in threaded installation with the lock nut, and the inner ring of the lock nut is provided with internal threads for being in threaded installation with the shaft head.
Preferably, the surface of the locking nut is provided with threaded holes for installing the fixing bolts in a circular array.
Preferably, one end of each fixing bolt is provided with a large-outer-diameter nut, and the large-outer-diameter nuts are in butt joint with the circular grooves.
The beneficial effects of the utility model are as follows:
1. the locking mechanism has the advantages of simple structure, low cost, convenient installation and disassembly, reusability and high maintenance convenience and economy;
2. the locking mechanism is compact in structure and small in axial size, and can realize locking layout of the drive axle in a smaller space;
3. the locking mechanism has high locking torque consistency and higher product stability;
4. the locking mechanism is reliable in performance, and the problem caused by loosening of the locking nut can be effectively avoided.
