Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide that a kind of reasonable in design, structure are simple, the novel annular knurl Minisize axial of accurate positioning, high lubricating effect.
For achieving the above object, the utility model provides following technological scheme: a kind of novel annular knurl Minisize axial, comprise cylindrical axis body, described axis body is disposed with the first knurled segment from left to right, first smooth section, second knurled segment, second smooth section and the 3rd smooth section, the diameter of described first knurled segment is 4mm, described first smooth section, the diameter of the second knurled segment and the second smooth section is 5.8mm, the diameter of described 3rd smooth section is 8mm, the first oil groove is provided with between described first knurled segment right-hand member and the first smooth section left end, the first gasket groove is provided with between described first smooth section right-hand member and the second knurled segment left end, the second gasket groove is provided with between described second knurled segment right-hand member and the second smooth section left end, the second oil groove is provided with between described second smooth section right-hand member and the 3rd smooth section left end, described 3rd smooth section has been wholely set positioning disk, described positioning disk outer wall is evenly provided with 4 locating slots, the bottom surface of described first oil groove and the second oil groove is provided with several oil storage tanks.
By adopting technique scheme, after axis body arranges positioning disk, be easy to just can accurately locate according to the locating slot on positioning disk when assembling, efficiency of assembling is higher, accurate positioning, compares and saves time; And lubricant oil can be stored in oil groove preferably after in the first oil groove and the second oil groove, oil storage tank is set, lubricant oil is not easily run off, high lubricating effect.
The utility model is set to further: the bottom surface of four locating slots on described positioning disk is all obliquely installed to the 3rd smooth section, and each locating slot bottom surface is all tangent with the 3rd smooth section outer surface.By this setting, vibrational power flow is more reasonable, uses convenient.
The utility model is also set to further: described first oil groove and the second oil groove bottom surface are all at least arranged 2 annular oil storage tanks.By this setting, oil storage tank quantity arranges rationally, and oil storage effect can be better.
The utility model is also set to further: described first oil groove and all recessed curved of the second oil groove bottom surface, and the first oil groove and the wide 2.5mm of the second oil groove.Oil storage tank vibrational power flow is reasonable, and oil storage effect can be better.
The utility model is also set to further: described first gasket groove and the second gasket groove are circular groove, and the width of the first gasket groove and the second gasket groove is 1.2mm, and the degree of depth of the first gasket groove and the second gasket groove is 1.4mm.By this setting, vibrational power flow is reasonable, uses convenient, reliable operation.
The utility model has the advantages that: compared with prior art, the utility model vibrational power flow is more reasonable, after axis body arranges positioning disk, be easy to just can accurately locate according to the locating slot on positioning disk when assembling, efficiency of assembling is higher, accurate positioning, compares and saves time; And lubricant oil can be stored in oil groove preferably after in the first oil groove and the second oil groove, oil storage tank is set, lubricant oil is not easily run off, high lubricating effect.
Below in conjunction with Figure of description and specific embodiment, the utility model is described in further detail.
