Problems solved by technology

These fields require gears with small weight, small transmission torque, stable transmission, and low noise, so gears made of engineering plastics are the first choice, but affected by temperature, the dimensions of plastic gears such as aperture, index circle diameter, and backlash will change. Disadvantages such as unstable transmission, loud noise, low transmission torque, easy wear, easy deformation, etc.
Later, the gears made of light aluminum alloy have the characteristics of light weight, low density, good plasticity, easy to master and easy processing of aluminum matrix composite technology, but their strength is still low and their wear resistance is poor. The transmission parts are limited. At present, most of the traditional gear production adopts the traditional cutting method, which has low material utilization rate, low production efficiency and high product cost.

Abstract

The invention provides a gear and a method for manufacturing the same. The gear comprises an alloy base body and a reinforcing body which is embedded in the alloy base body and is a gear framework woven from transverse steel wires and longitudinal steel wires in a staggered manner. By the method for manufacturing the gear, a process of performing two forging steps in one heat and an ion sputtering and spraying method are adopted. Compared with the prior art, the gear and the method for manufacturing the same maintain characteristics of high strength, high hardness, high temperature resistance and high heat conduction coefficient of the conventional steel and iron materials, also have characteristics of good plasticity and low density of an aluminum alloy material. By the method for manufacturing the gear, the obtained gear is complete in shape and dimension and is light through plastic deformation such as precision forging, tooth profile deformation is low, the wear resistance of a tooth surface is increased, meshing noise is low, and the gear is long in service life and has excellent popularization and application value.

Description

technical field [0001] The invention relates to the technical field of gears, in particular to a gear and a manufacturing method thereof. Background technique [0002] As one of the most basic parts for transmitting motion and power, gears have been widely used in the industrial field, especially in the detection of printing equipment, locomotives, ships, power plants, steel mills, railway tracks and other fields. These fields require gears with small weight, small transmission torque, stable transmission, and low noise, so gears made of engineering plastics are the first choice, but affected by temperature, the dimensions of plastic gears such as aperture, index circle diameter, and backlash will change. Transmission instability, loud noise, low transmission torque, easy wear, easy deformation and other shortcomings. Later, the gears made of light aluminum alloy have the characteristics of light weight, low density, good plasticity, easy to master aluminum matrix composite...
