Abstract

The utility model discloses a gear and shaft matched structure which comprises a transmission shaft and a transmission gear. The transmission gear is installed on the transmission shaft. The transmission gear comprises a gear hub, wherein one side of the gear hub is provided with transmission teeth, and the other side of the gear hub is not provided with transmission teeth. One side of the gear hub provided with the transmission teeth is in interference fit with the transmission shaft, and one side of the gear hub which is not provided with the transmission teeth is in transition fit with the transmission shaft. By adopting the mode, the stress concentration problem of the root portions of the gear teeth in the gear transmission process is solved.

Description

The cooperating structure of a kind of gear and axle
[technical field]
The utility model relates to the mechanical transmissioning technology field, particularly the cooperating structure of a kind of gear and axle.
[background technique]
In speed changer, the tradition axle mainly contains two kinds with the mode that is fixedly connected with of gear, a kind of employing key connects, and another adopts gear to be connected with the interference fit of axle, when adopting interference fit to connect, the tooth root position of gear produces larger tension force due to extruding being installed, and the larger this tension force of magnitude of interference is larger, in the gear transmission process, this tension force can have a strong impact on gear life, when the standard pitch diameter of gear less, this tension force on life-span of gear to affect meeting larger.
[model utility content]
The purpose of this utility model is to provide the cooperating structure of a kind of gear and axle, to solve the problems of the technologies described above.
To achieve these goals, the utility model adopts following technological scheme:
The cooperating structure of a kind of gear and axle, comprise transmission shaft and driving gear, and driving gear is arranged on transmission shaft; Driving gear comprises the tooth hub, and a side of tooth hub is provided with driving cog, and opposite side does not arrange driving cog; The tooth hub is not established a side and the transmission shaft interference fit of driving cog.
The utility model further improves and is: the tooth hub is provided with driving cog one side and transmission shaft transition fit.
The utility model further improves and is: the tooth hub does not arrange the inner ring of driving cog one side and is provided with between the inner ring of driving cog one side and adopts circular arc or groove transition.
The utility model further improves and is: the tooth hub does not arrange the inner ring of driving cog one side and is provided with between the inner ring of driving cog one side and adopts the arc groove transition.
The utility model further improves and is: described driving cog and tooth hub are the integral type structure.
With respect to prior art, the utlity model has following advantage:
The inner ring of tooth is that transition is connected with axle, has eliminated gear ring because the tension force that interference fit produces has been avoided because this tension force causes the risk of damage to gear.
[accompanying drawing explanation]
Fig. 1 is the utility model internal structure schematic diagram.
Wherein: 1, transmission shaft; 2, driving gear; 3, tooth hub; 4, driving cog; 5, groove.
[embodiment]
As shown in Figure 1, the cooperating structure of a kind of gear of the utility model and axle comprises transmission shaft 1 and driving gear 2.
Driving gear 2 comprises tooth hub 3, in a side of tooth hub 3, is provided with driving cog 4, and an other side is not established driving cog, and tooth hub 3 is provided with a side and transmission shaft 1 transition fit of driving cog, and driving gear 2 is not established a side and transmission shaft 1 interference fit of driving cog.
Driving cog 4 is the integral type structure with tooth hub 3, adopts that same blank is forged, the machining manufacture forms.
Driving gear 2 is arranged on transmission shaft 1.
Tooth hub 3 is not established the inner ring of driving cog one side and is provided with between the inner ring of driving cog one side and adopts circular arc or groove 5 transition.This groove 5 is preferably arc groove.
