Large-sized inner gear ring machining device

Abstract

The invention relates to a large-sized inner gear ring machining device which comprises a connecting part, a bent shell, a power transmission mechanism and a milling tool, wherein the connecting part can be connected with a tool post of a common gear hobbing machine; the bent shell is matched with an inner gear ring in shape; the power transmission mechanism can be used for transmitting power of the common gear hobbing machine; and the milling tool is connected to the power transmission mechanism. The connecting part comprises a bolt and a locating key, which are matched with the tool post of the original common gear hobbing machine. The transmission mechanism is a gear set, two ends of which are respectively matched with an output end of the tool post of the original common gear hobbing machine and an input end of the milling tool. After the structure is adopted, the original common gear hobbing machine can be utilized; the device is mounted on the tool post of the original common gear hobbing machine; and the power of the original gear hobbing machine is transmitted to the milling tool by the power transmission mechanism. The large-sized inner gear ring machining device provided by the invention can be designed and made according to parameters of the inner gear ring to be machined, can adapt to various machining requirements and has the advantages of simple structure, easiness in mounting and low manufacturing cost.

Description

technical field [0001] The invention relates to a device for milling gears, in particular to a device for processing large internal ring gears. Background technique [0002] Internal gears with internal ring gears are widely used in various mechanical transmissions. For small and medium-sized internal gears, gear hobbing machines can be used to complete processing, but internal gears with large diameters or high heights cannot be manufactured by existing equipment. The Chinese Invention Publication CN202291682U discloses a device for processing an inner ring gear, including a tool holder, a motor, a column, a guide rail, a milling cutter, and a rotary table. The horizontal guide rail is provided with a vertical column, and the column is provided with a tool holder. The tool holder can perform horizontal or vertical reciprocating linear motion on the column. The position corresponding to the tool holder on the guide rail is provided with a rotary table. The bottom of the tool...
