Embodiment 1

[0085]The gears processed on the end surfaces of the right end disc 1 and the left end disc 4 are internal gears, the double gears of the right planetary gear 2 and the left planetary gear 5 are all external gears, the right end disc 1, the left end disc 3, the right planetary gear 2 and the left planetary gear The tooth profile curve of the gear on the wheel 5 adopts an involute.

[0086] Eccentricity is

[0087] r H1 = 0.5mm, r H2 =2.5mm

[0088] The number of teeth is

[0089] z 1 =66,z 21 =65,z 23 =130,z 32 =131,z 35 =27,z 4 =14,z 53 =26,z 54 =13

[0090] Modulus is

[0091] m 1 = m 21 = m 23 = m 32 = 1 mm, m 35 = m 53 = m 54 = m 4 =5mm

[0092] The input speed and torque are

[0093] ω H1 =100rad / s, M H1 =50N.m, M H2max =1000N.m

[0094] The relationship between the number of teeth of each gear is as follows

[0095] (z 1 z 23 -z 21 z 32 )(z 4 -z 54 )(z 54 +z 53 )=(66×130-65×131)×(14-13)×(13+26)=2535

[0096] (z 4 z 53 -z 54 z 35 )...

Abstract

The invention relates to the field of few-tooth-difference planetary transmission, in particular to a few-tooth-difference planetary transmission device for realizing intelligent self-adaption to a working load. The intelligent self-adaptive few-tooth-difference planetary transmission device comprises a left planetary gear, a right planetary gear, a left end plate, a right end plate, a casing and a connecting member, wherein one end of the connecting member penetrates through the left planetary gear and the right planetary gear along the axial direction; end parts of two ends of the connecting member are separately and fixedly connected with the left end plate and the right end plate; the left planetary gear is simultaneously meshed with the left end plate and a tooth profile on the casing; the right planetary gear is simultaneously meshed with the right end plate and the tooth profile on the casing; and the left planetary gear, the right planetary gear, the left end plate, the right end plate and the casing form a force closed mechanism. According to the intelligent self-adaptive few-tooth-difference planetary transmission device disclosed by the invention, by using the force closed mechanism formed by the left planetary gear, the right planetary gear, the left end plate, the right end plate and the casing, the transmission device can automatically and steplessly adjust transmission ratio and output rotating speed according to changes of the load without depending on a measurement and control system, and is simple in structure and low in cost.

Description

technical field [0001] The invention relates to the field of planetary transmission with small tooth difference, in particular to a planetary transmission with small tooth difference that realizes intelligent self-adaptation to the working load. Background technique [0002] Due to the advantages of large transmission ratio, small size, high transmission efficiency and large load capacity, the planetary transmission with small tooth difference has been widely used in metallurgy, mining, robotics, aerospace and weaponry and other fields. The transmission ratio of the existing planetary transmission with small tooth difference is a fixed value. When the workload changes and the output speed needs to be adjusted to ensure the best operating state of the equipment, the speed of the drive device is generally adjusted by electrical control to adapt to the change. This method mainly relies on measurement and control, resulting in complex system structure and high cost. The self-ad...
