Abstract

The invention relates to a modeling method for a helical bevel gear. The method comprises the following steps of: 1, establishing a tooth profile curve parameterized module by using a computer, and completing a gear tooth surface curve by a tooth profile curve group or cloud points in the environment of parts; 2, establishing a gear tooth entity in the environment of parts; 3, establishing a conical gear tooth and root entity in the environment of parts; 4, annularly arraying the gear tooth entity in the environment of parts; and 5, combining the gear tooth entity and the conical gear root entity, and finishing to obtain a complete simulating body of a virtual three-dimensional gear. The invention provides a universal, simple and easy modeling method for the helical bevel gear, and the method is applicable for the construction of a three-dimensional entity model of various helical bevel gears.

Description

technical field [0001] The invention relates to a modeling method of transmission parts, in particular to a method for realizing the modeling of helical bevel gears by utilizing the powerful secondary development function of computer drawing software. Background technique [0002] Helical bevel gears are one of the most basic parts used to transmit parallel axis motion and power in the mechanical field, and are widely used in various mechanical equipment such as mining, metallurgy, construction and transportation. Compared with straight bevel gears, helical bevel gears have the advantages of high coincidence, stable transmission, low noise, and high load-carrying capacity. Due to the complexity and uniqueness of its structure, its design is difficult, and it is very difficult to process it with traditional gear cutters. Therefore, it has not been popularized and applied in industry, and there are few technical data about helical bevel gear transmission. With the rapid deve...
