Machining equipment and method for manufacturing various kinds of face gears through straight blade cutter

Abstract

The invention discloses machining equipment and method for manufacturing various kinds of face gears through a straight blade cutter. The equipment comprises the straight blade cutter, an existing bevel gear machine tool and special clamps capable of achieving machining of the various kinds of face gears, the spatial relationships of the machined face gears comprise orthogonality, oblique crossing, positive bias and inclined bias, machined face gear tooth forms include straight teeth, inclined teeth and herringbone teeth, the special clamps are used for clamping the straight blade cutter and the various kinds of face gears, and therefore the spatial relationships and the angle adjusting allocation needed by tooth form machining are achieved. The machining method for manufacturing the various kinds of face gears through the machining equipment comprises two-parameter and one-parameter envelope methods, straight blade cutter form producing planes and the tooth faces of the various kindsof machined face gears are in point contact in the two-parameter envelope method, the machining accuracy is high, the straight blade cutter form producing planes and the tooth faces of the various kinds of machined face gears are in linear contact, and the machining efficiency is high; and by means of the machining equipment and method, the manufacturing cost of the various kinds of machined facegears can be greatly reduced.

Description

Technical field: [0001] The invention relates to the field of gear manufacturing, in particular to processing equipment and a processing method for manufacturing various face gears with straight-edged cutters. Background technique: [0002] The bevel gears in the meshing transmission of cylindrical gears (small wheels) and bevel gears are called face gears, and their shaft angle range is 0°<γ<180°. Traditionally, the tooth surface of the face gear tooth is determined by the following method: based on the space meshing theory, the same as the small wheel and the face gear mesh transmission installation in actual use, when the small wheel rotates continuously around its axis and drives the face When the gear rotates, the envelope of the tooth surface family of the small wheel on the face gear is determined as the tooth surface of the face gear. The small wheel in this definition is called the shape wheel, and the difference between the shape wheel and the small wheel is ...

Problems solved by technology

However, on the one hand, these manufacturing methods are only suitable for the processing of orthogonal spur gears, and on the other hand, most of them are only suitable for the cutting of face gears. There are still many difficulties in realizing the grinding process. Orthogonal spur gears, such as the Gleason coniface gear processing method disclosed in US2012 / 0099939A1, such as figure 2 As shown, it will also bring the defect of large tooth surface deviation
