Abstract
The utility model relates to an axle specifically relates to a spindle, and it includes 6 smooth connecting rods that connect gradually the setting, the smooth connecting rod of first smooth connecting rod and second, the smooth connecting rod of second all adopt transition curved face to be connected with the smooth connecting rod of third, the smooth connecting rod of third within a definite time with fourth smoothness connecting rod, the smooth connecting rod of first smooth connecting rod, second, the diameter of the smooth connecting rod of third increase in proper order, the smooth connecting rod of the smooth connecting rod of third, fourth, the 5th smooth connecting rod, the diameter of the 6th smooth connecting rod reduce in proper order, first smooth connecting rod the same with the 6th smooth connecting rod diameter, the smooth connecting rod of second the same with fourth smoothness connecting rod diameter. The utility model discloses a spindle stress concentration is little, use intensity is high.
Description
Technical field
The utility model relates to a kind of axle, relates to a kind of main shaft particularly.
Background technique
Axle interts the mechanical parts rising in the middle of bearing or wheel or gear and transmit motion, is generally metallic cylinder, according to the purposes of reality, also has square shaft.Traditional main shaft in joint at right angles, easily produces stress and concentrates, easily cause main shaft to break, affect use safety in using process.
Model utility content
The purpose of this utility model is to provide a kind of stress and concentrates little, that working strength is high main shaft.
For achieving the above object, the technological scheme that the utility model provides is as follows: a kind of main shaft, it comprises the smooth connecting rod that 6 connect setting successively, described first smooth connecting rod and the second smooth connecting rod, second smooth connecting rod and the 3rd smooth connecting rod, transition cambered surface is all adopted to be connected between the 3rd smooth connecting rod with the 4th smooth connecting rod, described first smooth connecting rod, second smooth connecting rod, the diameter of the 3rd smooth connecting rod increases successively, the 3rd described smooth connecting rod, 4th smooth connecting rod, 5th smooth connecting rod, the diameter of the 6th smooth connecting rod reduces successively, described first smooth connecting rod is identical with the 6th smooth connecting rod diameter, described second smooth connecting rod is identical with the 4th smooth connecting rod diameter.
As wherein preferably a kind of, the radian of described transition cambered surface is pi/2.
Preferably, described main shaft is closed at the first smooth connecting rod and the 6th smooth interlinking lever end.
Compared with prior art, the beneficial effects of the utility model are: adopt cambered surface transition, avoid the vertical transition between two connecting rods, reduce stress and concentrate, can effectively prevent main shaft from breaking, can intert well in bearing or gear simultaneously, guarantee the compact siro spinning technology between them, and the location of installing, main shaft can stably be rotated, whole closed main shaft, adds the ability of the bearing load of main shaft, increases the service life.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the utility model main shaft;
Wherein, the 1, first smooth connecting rod, the 2, second smooth connecting rod, the 3, the 3rd smooth connecting rod, the 4, the 4th smooth connecting rod, the 5, the 5th smooth connecting rod, the 6, the 6th smooth connecting rod, 7, transition cambered surface.
Embodiment
Below in conjunction with accompanying drawing, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only some embodiments of the present utility model, instead of all, can not be interpreted as the restriction to the utility model content.
See Fig. 1, a kind of technological scheme that the utility model provides is: a kind of main shaft, it comprises the smooth connecting rod that 6 connect setting successively, first smooth connecting rod 1 and the second smooth connecting rod 2, second smooth connecting rod 2 and the 3rd smooth connecting rod 3, transition cambered surface 7 is all adopted to be connected between the 3rd smooth connecting rod 3 with the 4th smooth connecting rod 4, the radian of transition cambered surface 7 is pi/2, first smooth connecting rod 1, second smooth connecting rod 2, the diameter of the 3rd smooth connecting rod 3 increases successively, 3rd smooth connecting rod 3, 4th smooth connecting rod 4, 5th smooth connecting rod 5, the diameter of the 6th smooth connecting rod 6 reduces successively, first smooth connecting rod 1 is identical with the 6th smooth connecting rod 6 diameter, second smooth connecting rod 2 is identical with the 4th smooth connecting rod 4 diameter, at the first smooth connecting rod 1 and the 6th smooth connecting rod 6 end-enclosed, make main shaft completely closed.
Adopt cambered surface transition, avoid the vertical transition between two connecting rods, reduce stress to concentrate, can effectively prevent main shaft from breaking, can intert well in bearing or gear simultaneously, guarantee the compact siro spinning technology between them, and the location of installing, main shaft can stably be rotated, whole closed main shaft, add the ability of the bearing load of main shaft, increase the service life.
Technique scheme only embodies preferred implementation of the present utility model, can not be interpreted as the restriction to the utility model authorized range, and all distortion of making according to the utility model and improvement, all belong to the utility model protection domain.
Claims (3)
