Problems solved by technology

Since the existing planetary transmission structure uses a pair of cylindrical roller bearings, this structure can only bear radial force and cannot bear axial force, thus reducing the reliability of operation
In addition, the support of the existing planetary gear transmission structure is integrated, and the assembly, disassembly and repair of the planetary gear are extremely inconvenient

Embodiment Construction

[0009] Such as figure 1 As shown, the planetary transmission structure of the wind power gearbox includes a sun gear, a planetary carrier 1, a spindle 2, a planetary wheel bearing 3, a planetary carrier bearing 4 and a planetary wheel 5, and the planetary carrier 1 is installed on the box body 6 through the planetary carrier bearing 4 , the planetary wheel 5 is installed on the mandrel 2 through the planetary wheel bearing 3, the planetary wheel bearing 3 is a pair of tapered roller bearings and installed back to back, the middle of the inner ring of the tapered roller bearing is provided with an annular washer 7, and the middle of the outer ring It is an inward protrusion 8 on the planetary wheel. The inner ring on one side of the pair of tapered roller bearings is close to the step set on the spindle, and the inner ring on the other side is close to the step set on the planet carrier. The screw 9 is positioned on the washer 10 . The planet carrier 1 is a split structure, an...

Abstract

The invention relates to a planetary transmission structure of a wind power gear box, which comprises a sun gear, a planetary bracket, a mandrel, planetary gear bearings, planetary bracket bearings and a planetary gear. The planetary bracket is mounted on a box through the planetary bracket bearings, the planetary gear is mounted on the mandrel through the planetary gear bearings, and the planetary gear bearings are a pair of tapered roller bearings and are mounted back to back. The planetary transmission structure is capable of bearing bending moment generated by axial force of the planetary gear more effectively, load impact from paddles is prevented, running reliability of the gear box is improved, and the working requirement of the wind power gear box is met.

Description

technical field [0001] The invention relates to a planetary transmission structure, in particular to a planetary transmission structure of a wind power gearbox. Background technique [0002] Due to its large transmission ratio, stable transmission and large transmission torque, the planetary transmission mechanism is often used in mechanism transmission. Common planet carrier structures include double-wall integral type, double-wall split type and single-wall type. The double-wall integral planetary carrier has good rigidity; the double-wall separated planetary carrier has a more complex structure than the integral planetary carrier, and is mainly used for small transmission ratios. The single-wall planetary carrier has a simple structure and can accommodate more planetary gears. The planetary gear of the planetary transmission mechanism is mostly made into a hollow gear, so that the inner hole can be equipped with a planetary gear shaft or a bearing. [0003] The gearbox...
