Embodiment Construction

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

[0023] Such as figure 1 , Figure 5 Shown are a new type of flexible pin shaft load sharing structure that eliminates the axial inclination angle of the planetary wheel, and a new type of flexible pin shaft deformation schematic diagram that eliminates the axial inclination angle of the planetary wheel. The present invention is a novel flexible pin-shaft load-sharing structure for eliminating the axial inclination angle of the planetary wheel, which mainly consists of a planetary frame (1), a planetary wheel (2), a bearing (3), a retaining ring (4), and a pin shaft (5) , Composition of new bearing pin sleeve (6). Its installation process is: first insert the small aperture end of the pin sleeve (6) from the non-shoulder end of the pin shaft (5) until the shoulder of the pin shaft (5) and the small aperture of the new pin sleeve (6) end in full contact, then insert t...

Abstract

The invention discloses a novel flexible pin roll load equalizing structure capable of eliminating an axial dip angle of a planet wheel. The excircle of a pin roll sleeve (6) of the flexible pin rollload equalizing structure is a cylinder with a shaft shoulder at one end, steps are arranged inside the cylinder, and the cylinder is divided into three sections according to the hole diameter; from the end close to a planet carrier (1), the inner hole diameter is gradually reduced; and a ring-shaped slot is processed in one end, away from the planet carrier (1), of the novel pin roll sleeve (6).The novel flexible pin roll load equalizing structure is adopted to solve uneven load distribution problem of the planet wheel, and also can eliminate the axial dip angle, caused by load equalizing ofan existing flexible pin roll load-equalizing structure, of the planet wheel (2), so that a local wheel teeth failure phenomenon caused by uneven tooth-direction contact load is avoided.

Description

technical field [0001] The invention relates to the field of planetary gear transmission, in particular to a novel flexible pin shaft load sharing structure for eliminating the axial inclination of planetary gears. Background technique [0002] Due to its large coaxial output speed ratio, small size, and high load-carrying capacity, planetary transmissions are widely used in aerospace, shipbuilding, wind power and other industries. The planetary gear train consists of a sun gear, an inner ring gear and multiple planetary gears, and multiple planetary gears perform load sharing, 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 the load of each planetary gear is the same, but due to the existence of manufacturing and installation errors, the load distribution among multiple planetary gears is uneven, resulting in the failure of a single planetary gear due to...
