Problems solved by technology

Guo Hui of Northwestern Polytechnical University and others proposed a method of dressing the face gear worm grinding wheel on the CNC cylindrical gear grinding machine with the formed diamond roller and the standard cone roller respectively, but there are problems of low dressing accuracy and dressing efficiency
It can be seen that most of the dressing of the facing gear and worm grinding wheel needs to be carried out on special equipment, which lacks versatility. In addition, the dressing accuracy and efficiency need to be improved

Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] The invention discloses a forming and dressing method of a drum-shaped worm grinding wheel for face gear grinding. The drum-shaped worm grinding wheel is trimmed on a common worm grinding wheel gear grinding machine in a four-axis linkage manner by using a forming diamond roller, which has high dressing efficiency and dressing accuracy.

[0025] Commonly used ordinary worm grinding wheel gear grinding machine structure is as follows figure 1 As shown, the main movement axes include X1 radial feed axis, Y1 tangential feed axis, Z1 axial feed axis, A1 tool post rotary axis, B1 grinding wheel rotary axis, and C1 workpiece rotary axis, which can realize X1, Y1, Z1, A1, B1, C1 six-axis linkage. In addition, there are B2 roller rotation axis and C2 roller yaw axis. On an ordinary worm grinding wheel gear grinding machine, the axis ...

Abstract

The invention discloses a drum-shaped worm grinding wheel forming and finishing method for face gear grinding, and belongs to the field of gear manufacturing. A formed diamond roller is adopted, and the drum-shaped worm grinding wheel is trimmed on a common cylindrical gear worm grinding wheel gear grinding machine. Eccentric swing of the grinding wheel serves as a finishing stroke motion; based on a virtual center distance machining principle, deflection motion of the grinding wheel is decomposed, and double-edge forming finishing of the spiral face of the drum-shaped worm grinding wheel is achieved through four-axis linkage. By means of the method, the drum-shaped worm grinding wheel for face gear grinding has high finishing efficiency and precision, and face gear grinding can get rid of limitation of a special machine tool.

Description

technical field [0001] The invention belongs to the field of gear manufacturing, in particular to the grinding process of face gears, and in particular to a method for forming and dressing drum-shaped worm grinding wheels for grinding face gears. [0002] technical background [0003] The face gear pair has the advantages of large transmission ratio, high coincidence degree, compact structure, and insensitivity to installation errors, etc., and is mainly used in helicopter reducers. As one of the core parts of the helicopter power transmission device, the face gear must maintain excellent performance under high-speed and heavy-load conditions, which greatly increases the requirements for the accuracy of the tooth surface of the face gear. [0004] Grinding technology is the main means to improve the precision of gear tooth surface. Aiming at the worm grinding wheel grinding process of face gear, LITVIN et al. designed a face gear worm grinding wheel grinding machine, and bas...
