Structure design method of planet carrier and planet carrier

Abstract

The invention discloses a structure design method of a planet carrier and the planet carrier, and belongs to the technical field of planet carriers. The structure design method of the planet carrier comprises the following steps that a structural model of an initial planet carrier is established, wherein the initial planet carrier comprises a side plate; a first limit condition and a second limit condition are preset; according to the first limit condition, a first pin shaft hole is preset in the side plate, and according to the second limit condition, a second pin shaft hole is preset in the side plate; a preset hole opening area is arranged on the side plate, the preset hole opening area can cover the hole opening positions of the first pin shaft hole and the second pin shaft hole, and the initial planet carrier forms a semi-finished planet carrier. The planet carrier is designed and manufactured through the structure design method of the planet carrier. The structure design method of the planet carrier is simple and convenient, high in operability and high in applicability. The planet carrier is high in structural applicability, repeated labor is reduced, archiving and storing are convenient, workblanks are convenient to store, the delivery time is shortened, and the market competitiveness is improved.

Description

technical field [0001] The invention relates to the technical field of planetary carriers, in particular to a structural design method of the planetary carrier and the planetary carrier. Background technique [0002] In the design of multi-stage planetary gearboxes, gearboxes of the same type (or the same specification) have multiple speed ratio requirements. If non-standard designs are made for each speed ratio gearbox, there will be A large amount of repetitive labor has caused a huge waste of manpower and resources. In addition, because different designers have different design ideas, resulting in different design results, the complexity and variety of later products and drawings have brought many difficulties to data management. The planet carrier is one of the main components of the planetary gearbox. It is used to install the pins and bearings of the planetary gear. The planet carrier is the part that bears the largest external moment in the mechanism. The structural ...
