Embodiment 1

[0016] Embodiment 1: As shown in Figure 1, this gear CVT is mainly composed of a main transmission part, a differential speed part, a speed control part and a balance part. The balance part is a planetary gear train, and a differential is commonly used. Its function It is to maintain balance while turning. It consists of the sixth bevel gear 21, the fourth bevel gear 22, the fifth bevel gear 23 and the rotating arm 24, the sixth bevel gear 21 is connected with the first planet carrier H11, the fifth bevel gear 23 and the first center wheel K12 Connected, the rotating arm 24 is connected with the fourth bevel gear 22 . The power is first input from the rotating arm 24, and through the balance differential, one end is connected with the first planet carrier H11 of the input end of the main transmission, and the other end is connected with the output end of the same direction of rotation speed. When disabled, input and output are in the same direction. The main transmission par...

Embodiment 2

[0035] Embodiment 2: Another scheme of the balance part, as shown in FIG. 2 . The balance part is a planetary gear train, which is the same as the principle of the main transmission. The balance part is a planetary gear train, and the balance part is composed of the second planetary carrier 28, the second center wheel 25, the second double gear 26, and the output wheel 27. , the second center wheel 25 and the output wheel 27 are on the same straight line, the second center wheel 25 is connected with the transmission, the output wheel 27 is fixed with the sixth gear 7; the input end second planet carrier 28 is fixed with the eighth gear 30, The input end H of the main transmission is fixed with a seventh gear 29 which meshes with the eighth gear 30 , and the main transmission K is fixed with a fifth gear 6 which meshes with the sixth gear 7 on the output wheel 27 of the balance part. This scheme requires the H and V of the main drive to be in the same direction. The planet car...

Abstract

The method of realizing stepless speed varying method of the present invention is realized through controlling the speed difference of two gears in planetary gear train. The stepless gear speed variator consists of mainly main driving part, differential speed part, speed control part and balance part. The main driving part is one planetary gear train. The present invention his the advantages of simple structure, great driving power, small size, high efficiency, wide speed varying range and wide application range.

Description

technical field [0001] The invention relates to a gear stepless speed regulating device, in particular to a gear stepless speed changer, which can realize the automatic control of electromechanical integration. Background technique [0002] The current continuously variable transmissions include hydraulic continuously variable transmissions and continuously variable transmissions using gear mechanisms. The transmission of the hydraulic continuously variable transmission is unreliable and the efficiency is low. However, the current continuously variable transmission using a gear mechanism has complex structure, cumbersome speed change, large volume, heavy weight, small transmission ratio, and is inconvenient to use and maintain. In addition, the planetary gear train introduced in the current mechanical foundation is insufficient and has potential for development. Contents of the invention [0003] The present invention aims to solve the defects of the above-mentioned prio...
