Combined variable-speed-ratio walking reduction gear box and remote control tank

Abstract

The invention provides a combined variable-speed-ratio walking reduction gear box. The combined variable-speed-ratio walking reduction gear box comprises a left base with an upper opening, and furthercomprises a left upper cover which is fully sealed with the left base and a right upper cover which is fully sealed with a right base; a first speed ratio combination comprises a motor gear, a firstprimary dual gear, a first secondary dual gear, a first tertiary dual gear, a first quaternary dual gear, a bridge gear and a driving gear which are engaged in sequence; a second speed ratio combination comprises a motor gear, a second primary dual gear, a first tertiary dual gear, a first tertiary dual gear, a first quaternary dual gear, a bridge gear and a driving gear which are engaged in sequence; and a third speed ratio combination comprises a motor gear, a third primary dual gear, a second secondary dual gear, a first tertiary dual gear, a first quaternary dual gear, a bridge gear and adriving gear which are engaged in sequence. Compared with the prior art, the applicability is improved, the use is very convenient, the production cost is low, sundries are prevented from entering andoil spills are avoided, and the noise is reduced. The invention also provides a remote control tank.

Description

technical field [0001] The invention belongs to the technical field of remote control toys, and relates to a combination variable speed ratio travel reduction gear box and a remote control tank. Background technique [0002] At present, the 1:16 travel reduction gearboxes for remote control tanks on the market have only one fixed reduction ratio, and the same 0.8 modulus is used between the gears at all levels. Inside. A travel reduction gear box, including drive devices respectively located on both sides of the left stamped steel plate support and on both sides of the right stamped steel plate support, the drive devices all include a motor, motor teeth fixed on the motor, bridge teeth, drive teeth, three reduction shafts, and a drive shaft, the drive teeth are fixed on the drive shaft, and the bridge teeth are fixed on one of the reduction shafts and meshed with the drive teeth. The existing problem is: since this kind of walking reduction gearbox has only one fixed gear ...

AI Technical Summary

Problems solved by technology

The existing problem is: since this kind of walking reduction gearbox has only one fixed gear reduction ratio, it is difficult to adapt to the needs of different times and different styles of tanks, resulting in low applicability, that is, when repairing or replacing one of the gears Or for other parts, the entire left and right travel gearboxes must be removed from the bottom of the tank and the open steel stamping gearbox shells are disassembled, which makes it inconvenient to use; in addition, the driving device of the travel reduction gearbox is open It is sealed, so dust and grass roots are easy to enter, oil is easy to splash out, and the noise is loud
