Problems solved by technology

The transmission with ordinary gear structure is generally a manual transmission, which is relatively easy to achieve multiple gears and the ratio between the transmission ratios of adjacent gears is equal, but this type of transmission is relatively large
The transmission with planetary gear structure is generally an automatic transmission, which is small in size, but it is not easy to achieve multiple gears, and it is even more difficult to achieve equal ratios between adjacent gears.

Abstract

The invention relates to a proportional planetary transmission. Including mechanical system, control system, lubrication system, etc., including at least one planetary row, including multiple proportional or step ratio sub-transmissions. The ratios of each adjacent transmission ratio of the constant ratio or step ratio sub-transmission are equal ratios or step ratios. By selecting the structure of the planetary row (especially the characteristic parameters of the planetary row), the order of the types of the planetary row and various connections, the proportional value or step ratio value of each proportional or step ratio planetary row transmission can be formed into four types within a 15% deviation range. One of the successive proportional relations. By applying planetary gear multiplication, multiple proportional or stepped sub-transmissions can be connected in series to form a new proportional planetary transmission with abundant gears. The speed changer has small volume and abundant gear positions, and can be used as a speed changer in various equipment or as a part of transmission machinery.

Description

technical field [0001] The invention relates to a mechanical transmission, in particular to an equal ratio planetary transmission in which two or more planetary transmissions are connected in series to form more abundant gears by means of multiplication of planetary gears. Background technique [0002] In order to flexibly change the torque and speed of the power system in a wide range, many power machines are equipped with mechanical transmissions. Existing mechanical transmissions are divided into continuously variable transmissions and transmissions with gears. The transmissions with gears mainly include sideshaft transmissions, dual-clutch transmissions, planetary gear mechanical transmissions, etc., and can be divided into manual transmissions and automatic transmissions in terms of control. Existing gear transmission can also be divided into two kinds of common gear structure and planetary gear structure from mechanical structure. The transmission with ordinary gear s...
