Embodiment Construction

[0022] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with specific examples.

[0023] A wind power ring gear bearing seamless ring process, comprising the following steps:

[0024] (1) Material preparation: prepare the blank of the ring gear bearing;

[0025] (2) Heating: hoist the blank of the ring gear bearing into the orbital furnace for heating and heat preservation;

[0026] (3) Blank making: place the ring gear bearing after heating and heat preservation in the press blank mold, and perform upsetting, punching and end surface smoothing at the press station;

[0027] (4) Forging: The ring gear bearing after billeting is rolled with a ring rolling machine to cause continuous local plastic deformation, thereby achieving wall thickness reduction, diameter expansion, and cross-sectional profile forming;

[0028] (5) Excess heat ...

Abstract

The invention relates to the technical field of bearing manufacturing, in particular to a process for a seamless ring of a wind power ring gear, including material preparation, heating, billet making, forging, residual heat quenching, tempering, and machining. The wind power ring gear seamless ring process of the present invention changes the hardness of the surface and the core of the large ring that cannot be achieved by the conventional heat treatment process, and the hardness of the entire circumference is consistent, which solves the problem of uneven hardness and does not meet the standard, and improves the wind power gear ring. The mechanical performance of the seamless ring is changed from the original casting and hole reaming process to rolling, which saves labor, materials and energy.

Description

technical field [0001] The invention relates to the technical field of bearing manufacturing, in particular to a process for a seamless ring of a wind power ring gear. Background technique [0002] Bearing is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. According to the different friction properties of moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Among them, the rolling bearing has been standardized and systematized, but compared with the sliding bearing, its radial size, vibration and noise are larger, and the price is also higher. Rolling bearings are generally composed of four parts: outer ring, inner ring, rolling elements and cage. [0003] The processing technology of the inner and outer rings of wind power slewing bearings currently used is: Step 1: Manu...
