Method for grinding straight-cut gear on spline shaft grinding machine

Abstract

The invention relates to a method for processing an involute straight spur gear on a spline grinder, including the following steps: (1) producing a high precision profile shifted gear of which the parameters are consistent with that of a workpiece to be processed, (2) plating carbite or cubic boron nitride (CBN) particles on the profile shifted gear, (3) installing the profile shifted gear on theposition of the workpiece of the spline grinder to correct the flank shape of a grinding wheel, and (4) grinding the processed straight spur gear by the grinding wheel with corrected flank shape. As the shaping method is used for processing the gear, only one tooth socket needs to be processed by the plating operation; after abrasive particles are worn, a clad layer can be peeled off, and the plating operation is carried out again, namely that the basic gear with the identical parameters just needs to be produced by one time, thus compared with the prior art, the processing and production cost is greatly reduced; and further more, under the circumstance that a special shaping mechanism is not used on the spline grinder, the flank shape of the grinding wheel can be accurately corrected, and the production difficulty is also greatly reduced.

Description

technical field [0001] The invention relates to the field of gear processing, in particular to a method for chemically manufacturing a gear-type diamond grinding wheel. Background technique [0002] Involute cylindrical gear is the most widely used basic part of mechanical transmission technology, widely used in automobiles, machine tools, electric power, metallurgy, ships, mines, aviation, aerospace and other fields. As the requirements for gear precision and strength are getting higher and higher, it is necessary to use the gear grinding process to process the quenched tooth surface, and to meet the continuously improving requirements of the gearbox precision and other items. [0003] At present, the grinding methods are mainly divided into generating method and forming method. The generating method is further divided into the single-tooth surface grinding method including double-butterfly grinding wheel grinding and large-plane grinding wheel grinding, and the double-too...

Problems solved by technology

The key technology of forming method grinding is the dressing of the grinding wheel. Commonly used are involute template correctors, XY cam correctors, etc., all of which require special dressing mechanisms. The cost of dressing is high, the efficiency is low, and the accuracy cannot be guaranteed.

The spline shaft grinding machine has the advantages of low price and simple structure. After proper modification, it can be used for grinding spur gears by forming method. However, the dressing of the grinding wheel is the key issue. Most of the existing modification methods need to design a special grinding wheel dresser. low efficiency and high cost
