Large gear abrasive belt grinding machine

Abstract

The invention provides a large gear adhesive belt tooth grinding machine, and relates to a large gear machining device. The large gear adhesive belt tooth grinding machine comprises a machine base, a stand column, a rotating working table, a servo motor, a ball screw I and a power head, and is characterized in that the rotating working table is assembled at one end of the upper portion of the machine base, the stand column is assembled at the other end of the upper portion of the machine base, the power head is assembled on the stand column through a swallow-tail-shaped guide rail I, the servo motor is assembled on the stand column and connected with the ball screw I on the power head so as to drive the power head to move up and down along the swallow-tail-shaped guide rail I, and the rotating working table is assembled on the machine base through the guide rail, connected with a rapid oil cylinder on the machine base and driven by the rapid oil cylinder to move leftward and rightward along the guide rail. The large gear adhesive belt tooth grinding machine has the advantages of being novel in structure, easy and convenient to machine, convenient to use, high in grinding efficiency, high in adaptability, high in machined product quality, short in auxiliary time and the like, and therefore the large gear adhesive belt tooth grinding machine is a novel large gear adhesive belt tooth grinding machine which integrates economical efficiency and practicability.

Description

technical field [0001] The large-scale gear abrasive belt gear grinding machine of the present invention relates to a large-scale gear processing equipment. Background technique [0002] Large gears are mainly used in mining, metallurgy, nuclear power, wind power and other fields. At present, my country does not have equipment for processing large gear shafts and gears, and relies on imports. At present, many gear shafts of imported equipment need to be localized. [0003] At the end of the 19th century, in order to grind gear shaping knives, a large flat grinding wheel gear grinding machine was created in the United States. At the beginning of the 20th century, with the development of the automobile industry, Germany developed a conical grinding wheel gear grinding machine, and the United States used forming grinding wheels to grind automobile gears. In 1914, in order to improve the precision of gears, Switzerland manufactured a dish-shaped grinding wheel gear grinding mac...

AI Technical Summary

Problems solved by technology

The maximum modulus of the RZ801 gear grinding machine is 7mm or 8mm, but it can only be modified under the machine, and it must be equipped with a dresser, which is very uneconomical

[0005] The correct involute worm can be obtained by using large-grain diamond turning grinding wheels, but this kind of large-grain diamond is very expensive, so this dressing method is no longer used

Putting a flat diamond roller in the tangent plane of the imaginary worm base cylinder of the grinding wheel, the involute worm can be repaired theoretically, but because the diameter of the grinding wheel is constantly changing, the position of the diamond roller must be adjusted continuously, so in practice also difficult to achieve
