To the not enough of prior art, the to-be-solved problem of the utility model is to provide a high-efficient and low-cost skewed tooth ring rolling equipment that can realize skewed tooth ring gear processing, the technical scheme of adoption is:
helical tooth ring gear rolling equipment which characterized in that: the workpiece chuck is connected with a lathe spindle and rotates along with the lathe spindle, the workpiece chuck is provided with a positioning part at the front end and a middle transmission gear, the middle transmission gear is used for transmitting a left gear and a right gear on two sides, the left gear is connected with a left cutter gear through a left gear shaft, the left gear shaft is rotatably arranged on a left gear frame, the right gear is connected with a right cutter gear through a right gear shaft, the right gear shaft is rotatably arranged on a right gear frame, and the left gear frame and the right gear frame move relatively close to and away from each other; when the rolling mill works, the gear ring workpiece is arranged at the positioning part of the workpiece chuck and forms a gapless transmission meshing relation with the left cutter gear and the right cutter gear, and the gear ring workpiece, the left cutter gear and the right cutter gear both rotate actively.
The end faces of the two sides of the left cutter gear and the right cutter gear are respectively and fixedly provided with a front retaining ring and a rear retaining ring, the distance between the front retaining ring and the rear retaining ring is equal to the thickness of a processed gear ring workpiece, and the outer diameter of the front retaining ring and the rear retaining ring is larger than that of the left cutter gear and the right cutter gear.
According to the helical gear ring rolling equipment in the technical scheme, when the helical gear ring is rolled, firstly, a gear ring workpiece (steel pipe) is installed at the positioning part of a workpiece chuck and is pressed and fixed, then a lathe spindle rotates to drive the workpiece chuck and the gear ring workpiece to rotate actively, meanwhile, a middle transmission gear on the workpiece chuck drives a left gear, a right gear and a left cutter gear connected with the left gear and the right gear to rotate actively, so that a gapless transmission meshing relation is formed between the gear ring workpiece and the left cutter gear and the right cutter gear, then, through the relative approaching action of a left gear frame and a right gear frame, helical gear shapes can be rolled on the outer circle surface of the gear ring workpiece by the left cutter gear and the right cutter gear until helical teeth completely reach set parameter sizes, and then the helical gear ring is rolled; in the process, the front retaining ring and the rear retaining ring can just block the end faces of the two sides of the part of the gear ring workpiece to be formed with the helical teeth, so that the end face of the helical tooth gear ring is prevented from deforming, and the rolling forming of the helical teeth can be normally carried out.
In order to conveniently realize the relative approaching and separating actions between the left gear rack and the right gear rack, as a preferred technical proposal: the relative approaching and departing actions of the left and right gear racks are adjusted by an adjusting screw, the adjusting screw is in threaded connection with a left adjusting nut and a right adjusting nut, the left adjusting nut is fixedly arranged on the left gear rack, the right adjusting nut is fixedly arranged on the right gear rack, the left and right adjusting nuts are provided with internal threads in opposite rotating directions, and the shaft end of the adjusting screw is in transmission connection with a servo motor.
