Abstract
The efficient worm shaft disclosed in the utility model comprises a connecting end and a driving end, wherein a positioning groove is disposed between the connecting end and the driving end. When the efficient worm shaft in the utility model is connected to other parts, the efficient worm shaft is fixed by the positioning groove. When the driving end is rotated with a driving shaft, the efficient worm shaft in the utility model will not be moved axially, so that rotation efficiency is ensured.
Description
Technical field
The utility model relates to worm screw technical field, particularly a kind of efficient worm shaft.
Background technique
Worm screw is only to have one or several helical tooth, and forms the gear of gear pair with non-parallel with worm gear engagement.Worm geared advantage is that velocity ratio is large, compact structure, stable drive, noise free.Worm shaft is the important component part of worm gears, traditional worm shaft comprises connecting end and driving end, the end face of connecting end is sphere, connecting end is fixed for coordinating with other parts to install, transmission shaft, for being connected with endless screw electric motor, when mounted, withstands other parts by sphere, but when worm screw integral body is rotated with the transmission device of endless screw electric motor, easily produce and move axially.
Model utility content
The purpose of this utility model is for the defect of prior art and deficiency, and a kind of simple and reasonable efficient worm shaft is provided.
For achieving the above object, the utility model is by the following technical solutions:
Efficient worm shaft described in the utility model, comprises connecting end and driving end, between described connecting end and driving end, is provided with locating slot.
Further, described driving end is provided with tool withdrawal groove, wrom tooth and end successively, and described tool withdrawal groove position is corresponding with described locating slot position.
Further, the end face of described connecting end is sphere.
Further, described connecting end is provided with pin member A and pin member B.
Further, between connecting end and locating slot, be provided with cylinder, described cylinder is coaxial with connecting end, and the radius of cylinder is greater than the radius of described connecting end.
The beneficial effects of the utility model are: between connecting end and driving end, locating slot is set, when the utility model is connected with other parts, by locating slot, fix, when driving end rotates with transmission shaft, the utility model can not produce and move axially, and has guaranteed rotational efficienty.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
In figure:
1, connecting end; 3, locating slot; 4, tool withdrawal groove; 5, wrom tooth;
6, end; 7, pin member A; 8, pin member B; 9, cylinder.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Efficient worm shaft as shown in Figure 1, comprise connecting end 1 and driving end, between described connecting end 1 and driving end, be provided with locating slot 3, locating slot 3 is set between connecting end 1 and driving end, when the utility model is connected with other parts, fixing by locating slot 3, when driving end 1 rotates with transmission shaft, the utility model can not produce and move axially, and has guaranteed rotational efficienty.
Described driving end is provided with tool withdrawal groove 4, wrom tooth 5 and end 6 successively, and described tool withdrawal groove 4 positions are corresponding with described locating slot 3 positions, by tool withdrawal groove 4 is set, and Milling Process wrom tooth 5 while being convenient to the utility model production.
The end face of described connecting end 1 is sphere, has further guaranteed the connection effect of connecting end 1.
Described connecting end 1 is provided with pin member A7 and pin member B8, and pin member A7 is used for connecting supporting post, and pin member B8 is used for connecting speed change part, as speed changer.
Between connecting end 1 and locating slot 3, be provided with cylinder 9, described cylinder 9 is coaxial with connecting end 1, and the radius of cylinder 9 is greater than the radius of described connecting end 1, better defines the locating effect of locating slot 3 by cylinder 9.
The above is only better embodiment of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
