Description

a steering gear

technical field

The utility model relates to a steering gear, in particular to a steering gear applied to aircraft models, ship models and other models.

Background technique

With the continuous development of science and technology, steering gear has been widely used in aviation models, navigation models, and car models. Almost all models that need to operate their actions can be realized through steering gear. At present, the traditional steering gear usually includes a drive motor, a transmission gear set and other components. The drive motor is used to provide the original power, and the original power is directly transmitted to the transmission gear set, and the torque is adjusted through the transmission gear set, and the torque is transmitted. Give the rotation mechanism of the model, and then realize the steering of the model through the rotation mechanism. However, the traditional steering gear has the disadvantages of small torque, low efficiency, high noise and heavy weight, and needs to be further improved.

Contents of the invention

In order to overcome the deficiencies of the prior art, the utility model provides a steering gear with large torque, high efficiency, low noise and light weight.

The technical scheme that the utility model solves its technical problem adopts is:

A steering gear, comprising a machine base, a hollow cup motor and a speed change gear set driven by the hollow cup motor are installed in the machine base, and a connecting shaft extending to the outside of the machine base is installed on the final stage gear of the speed change gear set, and is characterized in that A pinion is installed in the base, and a transmission gear is installed on the output shaft of the hollow cup motor. The transmission gear meshes with the pinion, and the pinion meshes with the first stage gear of the speed change gear set.

As a preferred embodiment of the present invention, the transmission gear set includes a first-stage gear meshing with the pinion, a second-stage gear meshing with the first-stage gear, a third-stage gear meshing with the second-stage gear, and a The final gear that meshes with the third gear.

As another preferred embodiment of the present invention, the diameter of the hollow cup motor is 8 mm.

The beneficial effects of the utility model are: the utility model transmits the original power to the gear set through the pinion meshed with the transmission gear of the driving motor to change the output speed ratio of the gear set, and adjust the output speed ratio of the gear set to adjust The size of the torsion force makes it produce large torsion force and high efficiency, and the utility model adopts a hollow cup motor with a diameter of 8mm, which can reduce the noise of the steering gear and reduce the weight of the steering gear.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is the three-dimensional schematic view of the utility model;

Fig. 2 is a schematic sectional view of the utility model.

Detailed ways

With reference to Fig. 1, Fig. 2, a kind of steering gear disclosed by the utility model, this steering gear can be applied on aviation model, nautical model, car model, and it comprises machine base 1, and coreless motor 2 and motor 2 are installed in machine base 1 The transmission gear set 3 is driven by the hollow cup motor 2. The hollow cup motor 2 needs to use a hollow cup motor with a diameter of 8 mm. The use of the hollow cup motor can reduce the noise of the steering gear and reduce the weight of the steering gear. In the transmission gear set 3 The connecting shaft 4 extending to the outside of the base 1 is installed on the final gear, and the connecting shaft 4 can be connected with the rotating mechanism of the model to transmit the torque generated by the steering gear to the rotating mechanism of the model, and then realize the rotation of the model through the rotating mechanism. turn.

As shown in the figure, a pinion 5 is installed in the frame 1, and a transmission gear 6 is installed on the output shaft of the coreless motor 2, wherein the transmission gear 6 meshes with the pinion 5, and the pinion 6 and the transmission gear set 3 The first-stage gear meshes, so that the original power is transmitted to the gear set through the pinion meshed with the transmission gear of the drive motor, so as to change the output speed ratio of the gear set, and adjust the torque by adjusting the output speed ratio of the gear set. So that the torque generated by it is large and the efficiency is high.

Referring to Fig. 2, in this embodiment, the transmission gear set 3 adopted by the utility model includes a first-stage gear 31 meshing with the pinion 5, a second-stage gear 32 meshing with the first-stage gear 31, and a second-stage gear 32 meshing with the second-stage gear The third stage gear 33 meshed with 32 and the final stage gear 34 meshed with the third stage gear 33 .

The above embodiments have fully described the utility model, but the utility model is not limited to the above specific embodiments, and should not constitute a limitation to the utility model. When the utility model can also have other structural forms, such as the speed change gear set, other forms commonly used in the art can also be used, but no matter how it changes, as long as any improvement or modification made to the utility model by using the same principle, all belong to this invention. Within the protection scope of utility model claims.
