Continuously variable transmission without power interruption

Abstract

The invention discloses a continuously variable transmission without power interruption. The continuously variable transmission comprises a power input part, a main transmission part, a power output part, a braking part and a variable speed control part; the main transmission part comprises a case and a planetary gear train, the planetary gear train comprises a sun gear, a first-stage gear ring, a second-stage gear ring, a duplex planetary gear, a first-stage planet carrier, a second-stage planet carrier and a second-stage one-way clutch, the sun gear is in transmission connection with the power input part, the first-stage gear ring is braked through the braking part, engaging teeth are machined on the inner ring and the outer ring of the second-stage gear ring, one end of the duplex planetary gear is engaged with the first-stage gear ring and the sun gear, and the other end of the duplex planetary gear is engaged with the inner ring of the second-stage gear ring; and the second-stage planet carrier is in transmission connection with the power output part through the second-stage one-way clutch. The continuously variable transmission without power interruption has the advantages of being compact in structure and capable of achieving continuously variable speed under the condition that continuous power transmission is guaranteed, and the transmission performance is effectively improved.

Description

technical field [0001] The invention relates to the technical field of transmission gearbox structure, in particular to a stepless gearbox without power interruption. Background technique [0002] At present, the helicopter cannot give full play to its optimal aerodynamic performance in a complex and changeable working environment. The main reason is that its rotor speed is limited. Most of the gearboxes currently used cannot meet the requirements of the large speed range of the rotor. Therefore, it is necessary to develop a compact And can realize the gear box of stepless speed change, in order to expand the rotation speed range of rotor, stepless speed change can make helicopter maintain higher maneuverability and fuel economy under various working conditions. Contents of the invention [0003] In view of this, the object of the present invention is to provide a continuously variable transmission without power interruption so as to improve its transmission performance. ...
