Description
Technical field
It the utility model is related to the bearing and gear integrated structure of a kind of unit head.
Background technology
Traditional unit head, after the bearing on its driving shaft is arranged on spiral gear with curved teeth, make the length of driving shaft longer, together
When bearing and spiral gear with curved teeth it is distant, make the rigidity deficiency of driving shaft, stability deficiency, on driven group, helical arc
Gear and bearing it is distant so that the fulcrum force on driven shaft farther out, makes driven shaft rigidity not apart from spiral gear with curved teeth
Foot, easily shakes in running, produces noise, and friction increases and produces high fever, shortens the life-span of product.
Utility model content
The purpose of this utility model is to overcome the weak point in prior art, there is provided a kind of bearing of unit head and
Gear integrated structure.
In order to achieve the above object, the utility model uses following scheme：
The bearing and gear integrated structure of a kind of unit head, including shell, driving shaft and some driven group, the active

With the stability for increasing the rigidity of the driving shaft He improving driving shaft, described driven group include the second spiral gear with curved teeth, from
Moving axis and second bearing, the second helical arc gear are socketed on one end of the driven shaft, to drive the driven shaft
Motion, the second bearing and the second helical arc gear matches are simultaneously socketed on the gear hub of the second spiral gear with curved teeth
To shorten the length of the driven shaft, the rigidity of driven shaft is improved, and then improves chip performance, increases the life-span of gear, it is described
Second spiral gear with curved teeth agrees with the first spiral gear with curved teeth, when the driving shaft moves, passes through the first helical arc gear band
Move the second helical arc gear movement and then drive the driven shaft motion.
In one or more embodiments, described driven group includes left transfer group and right transfer group, the left transfer group and
The direction of motion of right transfer group is consistent, and the angle between the left transfer group and right transfer group is in 90 degree, to install multiple cutters.
In one or more embodiments, the second spiral gear with curved teeth includes left independent screw gear with curved teeth and right transfer spiral shell
Gear with curved teeth is revolved, the left independent screw gear with curved teeth is consistent with the direction of motion of right independent screw gear with curved teeth so that the left transfer group
It is consistent with the direction of motion of right transfer group.
In one or more embodiments, the left independent screw gear with curved teeth, right independent screw gear with curved teeth and the first spiral shell
The quantity for revolving gear with curved teeth is consistent.
Beneficial effect：The utility model provides the bearing and gear integrated structure of unit head, and spiral is socketed in using bearing
On gear with curved teeth, the length of driving shaft and driven shaft is shortened, while shortens the distance of bearing and spiral gear with curved teeth, makes stress branch
Point reach, protection of the bearing to driving shaft and driven shaft is improved, and then improve the rigidity of driving shaft and driven shaft, improve gear
Life-span.
