Embodiment Construction

[0012] A large single-wall cantilever integral planetary carrier, which is in the form of integral forging, has a planetary carrier body 1, and one end of the planetary carrier body is provided with 3 to 4 cantilevers 2 (that is, planetary shafts) for installing planetary gears along the circumference, and each cantilever A single self-aligning bearing 3 that realizes single-point floating support is installed on the top. The self-aligning bearing is positioned axially through the cantilever shaft shoulder 4 and the shaft circlip 5. The other end of the planet carrier body is connected to the next-stage transmission mechanism 8. Inner spline 6 structure, a single self-aligning bearing 7 that realizes single-point floating support is set on the planet carrier body.

[0013] The radial distance A between the center of the cantilever and the center of the planet carrier is 400-800mm.

Abstract

The invention discloses an integral planet carrier of a large-scale single-walled cantilever. The integral planet carrier is in an integral forging molding mode and is provided with a planet carrier body, 3-4 cantilevers for mounting planet wheels are arranged along the circumference at one end of the planet carrier body; a single self-aligning bearing realizing single point floating support is sleeved on each cantilever and axially positioned by a shaft shoulder and a shaft circlip of the cantilever; the other end of the planet carrier body is in an internal spline structure connected with the next transmission mechanism; and the single self-aligning bearing realizing the single point floating support is sleeved on the planet carrier body. The invention has reasonable structure and is integrally forged and molded so that a planet mechanism has compact structure, simplifies the assembly, improves the rigidity and the bearing capability, has favorable balance performance; meanwhile, theinternal spline structure is joined, thereby a favorable automatic self-aligning effect is achieved.

Description

Technical field: [0001] The invention relates to a planetary carrier of a planetary transmission. Background technique: [0002] The gear lifting mechanism of the jack-up offshore platform needs a lifting gearbox with compact structure, large output torque and super load capacity to achieve reliable transmission. The planet carrier is the key part of the lifting gearbox. Generally, the structure of the planetary carrier has three types: double-arm integral type, double-wall split type, and single-wall split type. There are defects in rigidity, bearing capacity, balance performance, and self-aligning effect. Invention content: [0003] The purpose of the present invention is to provide a large single-wall cantilever integral planet carrier with reasonable structure and good working performance. [0004] Technical solution of the present invention is: [0005] A large-scale single-wall cantilever integral planetary carrier, which is characterized in that: it is in the for...
