specific Embodiment approach

[0042] The specific embodiment: the present invention will be further described below:

[0043] The processing method of the gear with large modulus, large diameter and small width is characterized in that: the gear blank is formed by casting, with a split structure, casting in two halves during casting, and then connecting them into a complete circle with bolts; the specific method is as follows:

[0044] After the rough casting is formed, it is annealed to eliminate casting stress and control deformation;

[0045] roughing:

[0046] Roughly machine each half-gear on a floor boring machine, rough-machine the mating plane of each half-gear blank, leave a machining allowance of 10mm for each half-gear mating plane, and then form a full circle;

[0047] Roughly process the outer circle of the assembled gears and the two end faces in the width direction on the vertical lathe with a diameter of 6.3m, leaving an allowance of 36mm in the diameter direction and 16mm on each end fa...

Abstract

The invention relates to a machining method for large-modulus large-diameter small-width gears and solves the problems that machining large-modulus large-diameter small-width gears is difficult and severe deformation occurs easily during machining. The machining method is reasonable in machining process, rigidity of gears is increased greatly and gear deformation is effectively prevented.

Description

Technical field [0001] The invention involves a processing method of a gear, especially the processing method of a large -scale large -diameter small width gear. Background technique [0002] The large -diameter large diameter small width gear parameter is: the number M = 50mm, the number of teeth z = 113, the diameter of the top round DA = 5750mm, the division of the diameter D = 5650mm, the teeth width B = 200mm, the variable position X = 0 0, High tooth height H = 112.5mm, altitude E = 78.5mm, accuracy level 8HK (GB / T10095).Material 35CRMO. [0003] On one side of the gear width direction, there are 72 φ32mm diameter holes arranged in a uniform circle. There are concave round troughs with diameter φ50mm. The distance between the holes and holes is high.Point requirements. figure 1 For a local schematic diagram of the gear. [0004] Gear modulus M = 50mm is the maximum model specified in national standards.Large -molding gears are characterized by large structural size.Large ca...
