Example Embodiment

[0021] Example: such as figure 2 : The planetary gear 27 is supported on the planetary shaft 22 by two tapered roller bearings 26 without outer rings. The end of the bearing is locked with a round nut 25. The round nut 25 is equipped with an adjusting spacer 24 and a spring retainer 23 , Together with the round nut 25, it has a double protective effect on the bearing 26, which greatly improves the reliability of product operation. The planet shaft 22 and the planet pin 21 are interference-coupled, and the planet pin 21 and the carrier 31 are also interference-coupled. A round nut 30 is installed at the end of the planet pin 21 for axial positioning. Such as image 3 As shown, when the planetary gear 27 is under force, the planetary pin 21 is elastically deformed, and the offset is A. The limiting cone ring 29 has an overload protection function for the planet pin 21 when the planet gear 27 is overloaded.

Abstract

The invention provides an elastic support structure of a planet wheel. The elastic support structure of the planet wheel mainly comprises a bracket, the planet wheel, a bearing, a space ring and a planet pin, wherein the planet wheel is supported on a planet shaft by the support, at least one side end portion of the bearing is locked by a round nut, an adjusting space ring and a spring stop ring are arranged outside the round nut, the planetary shaft is sleeved on the planet pin and in interference link, and the bracket which is arranged on one side of the planet shaft is sleeved on the planet pin and in interference link. Bearings are two tapered roller bearings which are arranged side by side and are not provided with outer circles, and a round nut which has a radial positioning function is arranged on one end portion of the planet pin. The planet wheel is arranged between the bracket and the planet wheel, and a limit tapered ring which has an overload protection function on the planet pin is arranged under the condition of overload. The planet pin has elastic deformation and produces offset to effectively make up machining error of the planet wheel and a planet support, achieve the aim of good uniform load, and ensure synchronous meshing of multiple planet wheels.

Description

technical field [0001] The invention relates to a novel planet wheel elastic support structure, belonging to the technical field of power transmission mechanisms. Background technique [0002] In the planetary mechanism, the load equalizing mechanism is a difficult point in the design, and the load equalizing effect directly determines the reliability of the product operation; usually a sun gear or a planet carrier is used to float in a planetary mechanism, because the sun gear or planet carrier floats on the structure It is easier to handle, while the floating of the planetary wheel is usually more difficult to handle, such as figure 1 What is shown is a traditional planetary wheel rigid support structure, which is mainly composed of a planetary carrier 11, a planetary wheel 12, a bearing 13, a spacer 14, and a planetary pin 15; the above-mentioned traditional planetary wheel rigid support structure has the following disadvantages: [0003] 1. Due to the action of to...
