Abstract

The utility model relates to a transmission for moveable models on ground, which is composed of a bracket, a fixed shaft, a torque transmission shaft, a transmission gear set, etc., wherein, the transmission gear set comprises a ring gear, three small cylindrical gears, and three web gears, and the two ends of the toque transmission shafts are respectively provided with a rocker arm.

Description

Transmission for moveable models on ground

The utility model relates to the driver that uses on a kind of toy.

Being used for the driver of transferring power on the general toy often directly is contained in each gear and axle on the toys shell, and also will decide on the space of toy itself installation site of motor or other power set, this structure and installation method tend to bring some troubles, for example not quick detachable and repair, speed reducing ratio is little, power set and driver can not be common on other toy, can not form a series, thereby are unfavorable for reducing cost and improving the quality of products.

The purpose of this utility model is to provide a kind of land movable model driver at the deficiency of above-mentioned driver, its motor and driver are integrated, easy for removal and installation, level Four is slowed down, speed ratio is big, compact conformation can be used for number of patent application and is 94302581.8 land movable model--on the electric robot, also can be used for the movable model toy of other similar action.

The purpose of this utility model can reach like this: land movable model driver is made up of support, fixed axis, torque transmitting shaft and driving gear set etc., and driving gear set comprises a round bevel gear, three roller gear, three disk gears that diameter is bigger that diameter is less.Support is a stamping forming ㄩ type skeleton part, and the position that motor is installed is arranged at the support rear portion, in the middle of support fixed axis and torque output shaft is housed, and at the torque output shaft two ends rocking arm is housed, rocking arm and torque output shaft immovable fitting.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the outline drawing of the land movable model driver of the utility model;

Fig. 2 is the vertical view and the transmission system schematic diagram of the land movable model driver of the utility model.

See also Fig. 1 and Fig. 2, the land movable model driver of the utility model is made up of support 10, circle bevel gear 2, roller gear 3, disk gear 4, roller gear 5, disk gear 6, roller gear 7 and disk gear 8 etc.Support 10 is a stamping forming type part, and there is the position that motor M is installed at its rear portion, and mid-stent is equipped with fixed axis 11, and torque output shaft 12 is equipped with in the support front portion.

Circle bevel gear 2 is combined into one with roller gear 3, its center has a through hole and sky to be enclosed within on the fixed axis 11, disk gear 4 is combined into one with roller gear 5, its center has a through hole and sky to be enclosed within on the torque output shaft 12, disk gear 6 is combined into one with roller gear 7, its center has a through hole and sky to be enclosed within on the fixed axis 11, disk gear 8 is combined into one with cannulated sleeve 9 and fastening combined cover is contained on the torque output shaft 12, the all fastening rocking arm 14 that is equipped with at the two ends of torque output shaft 12,13 interval actions of figure hollow core sleeve.

From Fig. 2, can see that motor M is equipped with roller gear 1, roller gear 1 constitutes the one-level deceleration transmission with 2 engagements of circle bevel gear, roller gear 3 is meshed with disk gear 4 and constitutes the double reduction transmission, roller gear 5 is meshed with disk gear 6 and constitutes three grades of deceleration transmission, roller gear 7 is meshed with disk gear 8 and constitutes the level Four deceleration transmission, and total reduction ratio reaches 320--360:1; Change if the rotating speed of motor is a per minute 3000, then the swing speed by the rocking arm 14 on the torque output shaft 12 after four groups of gear reductions is a per minute about 10 times.

In sum, transmission for moveable models on ground of the present utility model has power set and reducing gear is integrated, compact conformation, easy for removal and installation, the advantage such as level Four is slowed down, and speed reducing ratio is especially big, and be convenient to develop series of products, be common on other toy that needs power, all structurally identical with the utility model, but its size driver different with module all should be considered as the utility model claim.
