An integral lightweight gear shaft and its manufacturing process

Abstract

The invention discloses an integrated type light-weight gear shaft. The gear shaft includes a central shaft part and a gear disc part, wherein the central shaft part is composed of a first shaft section, a second shaft section, a third shaft section, a fourth shaft section and a fifth shaft section, the first shaft section, the second shaft section, the third shaft section, the fourth shaft section and the fifth shaft section are sequentially connected from the left to the right and are coaxially arranged, the central shaft part is of a hollow structure, the inner and the outer diameters fromthe first shaft section to the fourth shaft section are sequentially increased, the inner and outer diameters of the fifth shaft section are less than the inner and outer diameters of the fourth shaftsection, a spherical shaft end is arranged at the end, away from the fourth shaft section, of the fifth shaft section, and a central through hole is formed in the spherical shaft end. According to the integrated type light-weight gear shaft, light-weight technology is adopted, and the invention provides the integrated light-weight gear shaft and a manufacturing technique thereof, manufacturing and machining are convenient, the use ratio of materials is high, energy consumption is low, the finished product has certain stream lines, metal density is high, and the combination properties of the product are excellent.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to an integral lightweight gear shaft and its manufacturing process. Background technique [0002] Energy saving and environmental protection have increasingly become the focus of attention of the whole society. With less consumption, producing more utility has become the goal pursued by the manufacturing industry. Therefore, lightweight technology has gradually attracted the attention of domestic and foreign manufacturing industries. In recent years, with the rapid development of the construction machinery industry, lightweight will become one of the main development technology directions of the industry. The lightweight of construction machinery has a direct impact on reducing steel consumption and energy consumption in corresponding production and transportation links, reducing energy consumption and exhaust emissions during operations, and reducing noise. The poten...
