Problems solved by technology

[0002] Generally, the transmission part in the power transmission assembly of the aircraft model is a shaft transmission. The shaft transmission is not wear-resistant and easy to damage. It is not easy to maintain and requires high assembly technology. The power gear set is large and heavy. When the helicopter encounters an accident, the bearing rotates in the opposite direction. Major damage to the aircraft

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings.

[0018] The power transmission assembly 100 of the present invention is installed in the fuselage body and the tail body of the aircraft model to constitute the power part of the aircraft model. It includes a power group 1, an empennage transmission unit 3 and a transmission member, and the empennage transmission unit 3 and the power group 1 are installed at both ends of the transmission member respectively. The work of the empennage transmission unit 3 is driven by the power pack 1 .

[0019] Power group 1 comprises motor bull gear 11, driving pulley 12, driving pulley cover 10 and main shaft 13, and main shaft 13 runs through motor bull gear 11, driving pulley 12 and driving pulley cover 10. The driving pulley 12 is placed on the driving pulley cover 10 and is installed in the motor bull gear 11, and the rotation of the whole power mechanism is driven by the rotation...

Abstract

The invention provides a power transmission assembly of a model airplane. The power transmission assembly comprises a power package, an empennage transmission unit and a transmission component. The transmission component is a circular pitch synchronous belt, and the empennage transmission unit and the power package are respectively arranged at two ends of the circular pitch synchronous belt. The power transmission assembly has the advantages that the transmission component is in such a transmission mode that an empennage can be driven by the circular pitch synchronous belt, and accordingly the shortcomings of easiness in damage, difficulty in maintenance and high assembling technical requirements of shaft transmission can be overcome; the power transmission assembly is in such a novel mode that a driving belt pulley is nested in a motor gear wheel, accordingly, the volume of the integral power transmission assembly can be decreased, and weight of the power transmission assembly can be reduced; a one-way bearing is arranged in the motor gear wheel, accordingly, a helicopter can slowly fall under accidental conditions, and damage to the airplane can be reduced.

Description

technical field [0001] The invention relates to the field of model airplanes, in particular to a power transmission assembly of model airplanes. Background technique [0002] Generally, the transmission part in the power transmission assembly of the aircraft model is a shaft transmission. The shaft transmission is not wear-resistant and easy to damage. It is not easy to maintain and requires high assembly technology. The power gear set is large and heavy. When the helicopter encounters an accident, the bearing rotates in the opposite direction. Significant damage to the aircraft. Contents of the invention [0003] Based on the deficiencies of the prior art, the main purpose of the present invention is to provide a power transmission assembly of an aircraft model that is wear-resistant and easy to assemble and maintain. [0004] In order to achieve the above-mentioned purpose, the present invention provides a power transmission assembly of an airplane model, including a po...
