In mechanical designs, axial positioning of the drive shaft components or bearings is an important and difficult task in mechanical designs. If an unreliable axial positioning device is adopted, the positioning failure is likely to occur, so that equipment failure is caused, the smooth production is affected, and unnecessary economic loss is caused.
Conventional axial positioning devices typically employ a conventional round nut plus locking washer. The device has the working principle that the inner ring of the locking gasket is clamped in a stop groove on the transmission shaft, and the outer ring is clamped in a stop groove on the outer circle of the round nut, so that the aim of locking is fulfilled.
The disadvantages of the conventional axial positioning device are: 1. when the device works, the locking purpose is achieved through the bending deformation of the locking gasket, and the locking plate is seriously deformed during the working, so that the device cannot be repeatedly installed for many times. 2. Because the locking plate is thinner, the thickness is only 1mm, the locking force is smaller, and the phenomenon that the locking plate is sheared to fail easily occurs, so the reliability is lower.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provide the axial positioning device for the transmission shaft, which has the advantages of simple structure, convenience in installation, high reliability, reusability and the like.
The aim of the utility model can be achieved by adopting the following technical scheme:
the utility model provides a transmission shaft axial positioning device, includes round nut, axial locking groove, a plurality of radial stop plate mounting groove, stop plate, screw and locking gasket, the round nut passes through screw-thread fit assembly on the transmission shaft, wherein, be equipped with axial locking groove on the screw face that transmission shaft and round nut matched with, there is a plurality of radial stop plate mounting groove along circumferencial direction equipartition on the terminal surface of one side of round nut, the tank bottom of every radial stop plate mounting groove is equipped with a screw hole along axial extension, on screwing in the transmission shaft with the round nut, when one of them radial stop plate mounting groove on the round nut and axial locking groove circumference counterpoint, with the stop plate packing into radial stop plate mounting groove and axial locking inslot, link together stop plate and round nut through screw and locking gasket to realize the axial positioning of transmission shaft.
Further, the round nut is a locking round nut.
Further, the number of the radial stop plate mounting grooves is 12.
Further, the axial locking groove has a width greater than a width of the radial stop plate mounting groove.
Compared with the prior art, the utility model has the following advantages and beneficial effects:
the axial positioning device has the advantages of simple structure, convenience in installation and the like. When the device works, the whole device has no destructive damage to parts, so that the device can be repeatedly installed for a plurality of times. Meanwhile, the thickness of the stop plate can be designed according to actual requirements, and the thicker the thickness is, the larger the shearing force can be born, the higher the reliability is, and the thickness is more than 5 times that of a traditional axial positioning device.
