A processing method and processing system for a precision worm gear pair

Abstract

The invention discloses a machining method and system for a precise worm gear pair. The machining method comprises the following steps that 1, a worm is prepared, and the worm is prepared by using a worm machining device; 2, hobbing is conducted, a hob is mounted on a worm gear machining device, hobbing is conducted on a gear billet, and a rough machined worm gear is prepared; 3, strong gear shaving or strong gear lapping is conducted, a shaver or a plover wheel is grinded firstly by using a worm grinder, the hob on the worm gear machining device is dismounted, the grinded shaver or the ploverwheel is replaced and mounted, strong shaving or strong gear lapping is conducted on the obtained rough machined worm gear, and thus a fine machined worm gear is obtained; 4, phase disposing assemblyis conducted on the prepared worm gear and the prepared worm so that the same parts in error curves of the worm gear and the worm are counteracted with each other through phase disposing assembly; and 5, resistance shaving or gear lapping is conducted by using the shaver or the plover wheel, and assembly is adjusted. The step 3, 4 and 5 are all conducted under monitoring of an instrument. The machining method can obviously improve the precision and the machining efficiency of the worm gear pair.

Description

technical field [0001] The invention relates to mechanical processing, in particular to a processing method and a processing system of a precision worm gear pair. Background technique [0002] The worm gear pair is composed of a worm wheel and a worm screw. It is an excellent and basic mechanical transmission component. It has the characteristics of large transmission ratio, large torque, stable transmission, strong bearing capacity, self-locking ability, and high transmission precision. It is used in high-grade Gear machine tools, precision CNC machining centers, observatories, high-end elevators and advanced weapons are widely used in many fields. In recent years, although all kinds of direct drive motor transmission and hydraulic transmission have also made great progress, in some large power machinery fields, such as mining, metallurgy, aircraft carrier, wind power and other fields, the pursuit of "big" is endless, which makes large The technical advantages of the large...

Problems solved by technology

Even if the worm gear machine has high precision, the processing accuracy of the worm gear pair cannot be guaranteed, so the high-precision worm gear machine is only a necessary but not sufficient condition for the preparation of precision worm gear pairs.

However, it is almost impossible to make the accuracy of the worm gear machine, tool and worm involved in the error contribution of the worm gear pair reach high precision at the same time. This is the essential reason why the accuracy of the worm gear pair in my country has not been able to improve for a long time
