Abstract

The utility model discloses a steering engine, comprising a base. A coreless motor and a change gear set driven by the coreless motor are installed in the base, and the last-stage gear of the change gear set is provided with a connecting shaft extended out of the base. The utility model is characterized in that a pinion gear is installed in the base, so the speed can be increased by about 1.4 times. The output shaft of the coreless motor is provided with a drive gear which is engaged with the pinion gear, and the pinion gear is engaged with the first-stage gear of the change gear set. The utility model has the characteristics of large torque, high efficiency, low noise and light weight.

Description

A kind of steering wheel

Technical field

The utility model relates to a kind of steering wheel, particularly a kind of steering wheel that is applied on model plane, ship model or the like the model.

Background technology

Along with the continuous development of science and technology, steering wheel is used widely in model airplane, model ship, car mould, and nearly all model of its action of operation that needs all can be realized by steering wheel.Traditional steering wheel has generally included parts such as CD-ROM drive motor, change-speed gearing group at present, CD-ROM drive motor is in order to provide original power, and this original power directly is transferred to the change-speed gearing group, by the change-speed gearing group to regulate torque magnitude, and torsion is transferred to the rotating mechanism of model and then turning to by the rotating mechanism implementation model.Torsion is little, efficient is low, noise is big, the shortcoming of Heavy Weight but traditional steering wheel all has, and is further improved.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides that a kind of torsion is big, efficient is high, noise is little, lightweight steering wheel.

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

A kind of steering wheel, comprise support, the change-speed gearing group that the drag cup motor is installed in the support and drives by the drag cup motor, be equipped with on the final stage gear of change-speed gearing group and extend to the outer connecting axle of support, it is characterized in that being equipped with in the support pinion, on the output shaft of described drag cup motor travelling gear is installed, described travelling gear and pinion, the first order gears engaged of pinion and change-speed gearing group.

As the utility model preferred embodiment, described change-speed gearing group comprise with the first order gear of pinion, with the second level gear of first order gears engaged, with the third level gear of second level gears engaged and with the final stage gear of third level gears engaged.

As the preferred another kind of embodiment of the utility model, the diameter of described drag cup motor is 8mm.

The beneficial effects of the utility model are: the utility model is transferred to gear train by the pinion that the travelling gear with CD-ROM drive motor meshes with original power, to change the output speed ratio of gear train, and by adjusting the output speed ratio of gear train, regulate the size of torsion, thereby make the torsion of its generation big, the efficient height, and the utility model employing diameter is the drag cup motor of 8mm, can reduce the steering wheel noise, alleviate the weight of steering wheel.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a schematic perspective view of the present utility model;

Fig. 2 is a generalized section of the present utility model.

The specific embodiment

With reference to Fig. 1, Fig. 2, the disclosed a kind of steering wheel of the utility model, this steering wheel can be applicable to model airplane, model ship, on the vehicle model, it comprises support 1, the change-speed gearing group 3 that drag cup motor 2 is installed in the support 1 and drives by drag cup motor 2, it is the drag cup motor of 8mm that this drag cup motor 2 needs to adopt diameter, adopt this drag cup motor can reduce the steering wheel noise, alleviate the weight of steering wheel. the connecting axle 4 that extends to outside the support 1 is installed on the final stage gear of change-speed gearing group 3, this connecting axle 4 can be connected with the rotating mechanism of model, be transferred to the rotating mechanism of model and then turning to the torsion that steering wheel is produced by the rotating mechanism implementation model.

As shown in the figure, pinion 5 is installed in support 1, travelling gear 6 is installed, wherein travelling gear 6 and pinion 5 engagements, the first order gears engaged of pinion 6 and change-speed gearing group 3 on the output shaft of drag cup motor 2, the pinion that meshes by the travelling gear with CD-ROM drive motor is transferred to gear train with original power like this, with the output speed ratio of change gear train, and by adjusting the output speed ratio of gear train, the size of regulating torsion, thereby make the torsion of its generation big, the efficient height.

With reference to Fig. 2, in the present embodiment the change-speed gearing group 3 that adopts of the utility model comprise with the first order gear 31 of pinion 5 engagements, with the second level gear 32 of first order gear 31 engagements, with the third level gear 33 of second level gear 32 engagements and with the final stage gear 34 of third level gear 33 engagements.

Above embodiment has carried out sufficient explanation to the utility model, and still, the utility model is not limited to above-mentioned specific embodiment, more should not constitute restriction of the present utility model.The version that other also can be arranged when utility model; also can adopt other habitual form of this area as the change-speed gearing group; no matter but how it changes; so long as any improvement or the modification that adopt same principle that the utility model is done all belong within the scope of the utility model claim protection.
