Problems solved by technology

Therefore, the deformation caused by various factors will cause the gears to not be completely meshed in the tooth direction during the transmission process, and the resulting unbalanced load and impact will seriously affect the life of the gears.
[0003] If the above problems are solved by reducing the manufacturing and installation errors as much as possible according to the traditional thinking, it will lead to an increase in the cost of gear manufacturing, and the actual production and manufacturing proves that the effect is not very obvious and effective

Embodiment Construction

[0014] According to the research on the basic theory and manufacturing process of heavy-duty gear meshing, according to the "bottom-up" thinking, the technical scheme of the present invention is as follows: figure 1 . This route starts with the static analysis of the gearbox, seeks the load distribution curve based on the tooth direction, and compares the results of the drum shape modification and the new modification method through Romax simulation analysis to obtain the modification amount of the MW-level wind power gearbox gear. Maximizes gear mesh performance and minimizes mesh errors.

[0015] Since the wind power gearbox is in a complex environment of variable direction and load all year round, it is difficult to solve problems such as unbalanced load, meshing in, and meshing out impact at one time with a single modification method. Therefore, a new comprehensive method of gear modification is proposed for MW-class gearboxes and their actual environment; the modificatio...

Abstract

The invention relates to a gear modification method based on uniform load distribution. The method is characterized by comprising the following steps: (1) carrying out integral modeling on the MW-level wind power gear box by utilizing Romax software, carrying out analogue simulation on a model under a rated working condition, and determining a tooth upward load distribution curve; (2) deducing a corresponding modification curve and a specific modification amount according to the obtained load distribution curve; and (3) verifying the comprehensive gear modification method based on uniform load distribution under an equivalent load working condition. Aiming at the practical application condition of the MW-level wind power gear box, the invention provides a gear modification comprehensive method according to a tooth direction load distribution curve, and tests prove that the problems of unbalance loading of a heavy-duty gear and non-uniform distribution of tooth direction loads can be better solved.

Description

technical field [0001] The invention relates to a gear modification method based on uniform load distribution. Background technique [0002] Involute cylindrical gear transmission has many advantages such as relatively stable transmission, relatively compact structure, and simple and convenient manufacturing process. Even in the ideal state where manufacturing and installation errors are completely avoided, the ideal standard involute gear cannot meet the actual requirements in the actual meshing transmission process. Especially with the continuous increase of the gear speed and load, the deformation of the gear also begins to increase significantly, and the deformation of various load-carrying support systems such as the gear shaft and bearings also increases accordingly. Therefore, the deformation caused by various factors will cause the gears to not be completely meshed in the tooth direction during the transmission process, and the resulting unbalanced load and impact w...
