Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] like figure 1 , Figure 5 Shown are a flexible pin shaft load sharing structure that eliminates the axial inclination of the planetary wheel, and a flexible pin shaft deformation principle diagram that eliminates the axial inclination of the planetary wheel. The present invention is a flexible pin shaft load-sharing structure for eliminating the axial inclination angle of the planetary wheel, which mainly consists of a planet carrier (1), a planetary wheel (2), a bearing (3), an elastic retaining ring (4), a pin shaft (5), The pin sleeve (6) is composed. Its installation process is as follows: first insert the small bore end of the pin bushing (6) from the shoulderless end of the pin shaft (5) until the shoulder of the pin shaft (5) and the small bore end of the pin bushing (6) Complete contact, the smallest diameter part of the pin sleeve (6) and the pin (5)...

Abstract

The invention discloses a novel flexible pin-shaft load-sharing structure for eliminating the axial inclination angle of planetary gears. The outer circle of the pin-shaft sleeve (6) of the flexible pin-shaft load-sharing structure is a cylinder with a shoulder at one end, and the inside is a ladder. Divided into three sections, starting from the end close to the planet carrier (1), the internal aperture decreases successively, and the end of the new pin sleeve (6) away from the planet carrier (1) is processed with an annular groove. The use of this new flexible pin-shaft load sharing structure not only solves the problem of uneven load distribution among the planetary wheels; at the same time, it can also eliminate the planetary wheel (2) shaft To avoid partial failure of gear teeth caused by uneven distribution of tooth contact load.

Description

technical field [0001] The invention relates to the field of planetary gear transmission, in particular to a flexible pin shaft load-sharing structure for eliminating the axial inclination of the planetary gear. Background technique [0002] Planetary transmissions are widely used in aerospace, shipbuilding, wind power and other industries due to their large coaxial output speed ratio, small size, and high bearing capacity. The planetary gear train is composed of a sun gear, an inner gear and a plurality of planetary gears, and the multiple planetary gears carry out load distribution, so the planetary gear train can achieve a large transmission ratio in a small volume. In the design and calculation of the strength of the gear train, it is assumed that each planetary gear has the same load. However, due to the existence of manufacturing and installation errors, the load distribution among multiple planetary gears is uneven, resulting in failure of a single planetary gear due ...
