Problems solved by technology

[0002] Thin-walled spoke-type gears are characterized by relatively thin web walls, and processing will bring certain difficulties. Subsequent carburizing and quenching processing of thin-walled spoke-type gears will make it difficult to control the deformation size, which is difficult for processing. Cause difficulty, but also cause hidden dangers to quality

Embodiment Construction

[0011] The present invention will be further described now in conjunction with accompanying drawing. These drawings are simplified schematic diagrams only to illustrate the basic structure of the present invention in a schematic way, so they only show the components relevant to the present invention.

[0012] Such as figure 1 As shown, a thin-walled spoke-type large gear has a wheel belly, and the wheel belly has a weight-reducing hole 6 formed after carburizing, and the wheel belly has a wheel belly inner ring 1, a wheel belly outer ring 2, a wheel belly The belly wall, the inner ring of the wheel belly 1 has a shaft hole for installing a gear shaft, the outer ring of the wheel belly 2 has a gear 3, and the wall of the wheel belly is between the adjacent weight-reducing holes 6, and the inner ring of the wheel belly 1 With lifting screw hole 4.

[0013] The inner ring 1 of the belly, the outer ring 2 of the belly, the wall of the wheel belly and the gear 3 are carburized, q...

Abstract

The invention relates to a thin-wall spoke type large gear which is provided with a wheel abdomen, wherein the wheel abdomen is provided with lightening holes formed by processing after carbonization, and is provided with a wheel abdomen inner ring, a wheel abdomen outer ring and a wheel abdomen wall; the wheel abdomen inner ring is provided with a shaft hole in which a gear shaft is mounted; the wheel abdomen outer ring is provided with a gear; the wheel abdomen wall is arranged between the adjacent lightening holes; the wheel abdomen inner ring is provided with lifting screw holes; the number of the lifting screw holes of the wheel abdomen inner ring is two; the wheel abdomen inner ring is provided with a helical oil groove; and the lifting screw holes are communicated with the helical oil groove through a tapered passage. The structure of the conventional thin-wall spoke type large gear is changed, the lightening holes are formed by processing after the carbonization, by this time, the lightening holes are processed to the required sizes, so that the deformation due to heat treatment is improved and controlled effectively; then through the additionally adopted lifting screw holes, a product part can be lift to be subjected to subsequent heat treatment technologies such as quenching and tempering, so that the strength of the whole product part is improved well, and the usability of the product part is improved.

Description

technical field [0001] The invention relates to a thin-wall spoke type large gear. Background technique [0002] Thin-walled spoke-type gears are characterized by relatively thin web walls, and processing will bring certain difficulties. Subsequent carburizing and quenching processing of thin-walled spoke-type gears will make it difficult to control the deformation size, which is difficult for processing. Cause difficulty, but also cause hidden dangers to quality. Contents of the invention [0003] The technical problem to be solved by the present invention is: to overcome the deficiencies of the prior art, to provide a large gear with a thin-walled wheel and abdominal wall, to improve the strength of the whole product, and to improve the performance of the product. [0004] The technical solution adopted by the present invention to solve the technical problem is: a thin-walled spoke-type large gear with a wheel belly, the wheel belly has a weight-reducing hole formed aft...
