Abstract
The utility model discloses a transmission shaft and belongs to the technical field of mechanical parts. The transmission shaft provided by the utility model comprises a first connection part, a second connection part, a third connection part, a fourth connection part, a fifth connection part and a sixth connection part which are coaxially connected in sequence, wherein outer thread structures are respectively arranged on the second connection part and the fifth connection part; the two outer thread structures have opposite spiral directions; knurls are respectively arranged at the both ends of the third connection part; three annular flutes are arranged at the middle part of the third connection part in the radial direction; three key grooves for flat keys are uniformly distributed on the fourth connection part in the circumference direction. The transmission shaft provided by the utility model has the advantages of simple structure, convenience in mounting, accurate positioning and high stability, and the service life of the transmission shaft is prolonged.
Description
Technical field
The utility model belongs to component of machine technical field, especially relevant with a kind of transmission shaft.
Background technique
Transmission shaft is generally used for connecting and driving force, and it is inconvenient that current transmission shaft is installed location, makes to connect unstable, and easily causes in use for some time part loosening, affects the normal work of other connected elements.
Model utility content
The purpose of this utility model is intended to overcome the above-mentioned defect that prior art exists, and firmly New-type transmission shaft of a kind of installation location convenience, stable connection is provided.
For this reason, the utility model is by the following technical solutions: a kind of transmission shaft, it is characterized in that, described transmission shaft comprises coaxial the first joint, the second joint, the 3rd joint, the 4th joint, the 5th joint and the 6th joint connecting successively, on the second joint and the 5th joint, be respectively arranged with external thread structure, two external thread structure Hand of spiral are contrary, the 3rd joint two ends are respectively arranged with annular knurl, the 3rd joint middle part is radially provided with three annular grooves, is circumferentially evenly equipped with three flat key keyways on the 4th joint.
Use the utility model can reach following beneficial effect: by three flat key keyways are set, to improve the position stability that footpath makes progress; The worm structure that spiral is contrary is set, effectively prevents from causing part loosening after long-time use; Radially be provided with three annular grooves, not only can play axial limiting effect, also can in annular groove, add lubricant oil, play oil storage lubrication effect simultaneously; At the 3rd joint two ends, annular knurl is set, increases frictional force, convenient installation; The utility model is simple in structure, easy for installation, registration, stability are high, has extended the working life of transmission shaft.
Accompanying drawing explanation
Fig. 1 is the utility model perspective view.
