Embodiment Construction
[0008] Below in conjunction with accompanying drawing, the present invention is described in further detail:
[0009] A titanium alloy wear-resistant gear, comprising a wheel body (1), gear teeth (2), tooth grooves (3), and key grooves (4). The wheel body (1) is made of medium carbon steel or medium carbon steel alloy material, and the outer surface of the gear teeth (2) and tooth grooves (3) is made of 1-2 mm titanium alloy resistant Grinding layer (5). The titanium alloy wear-resistant layer contains 5% aluminum, 5% vanadium, 5% molybdenum, 3% tungsten, 3% chromium, and balance titanium and incidental impurities. The titanium alloy wear-resistant layer wheel is closely combined with the outer surface of the tooth (2) and the tooth groove (3), and the surface hardness can reach 750HV to 850HV, with an ultimate tensile strength of 178-188ksi and low friction coefficient corrosion resistance , smooth surface and low noise.

Abstract
The invention designs an abrasion-resistant titanium alloy gear and belongs to components and parts of mechanical transmission mechanisms. The abrasion-resistant titanium alloy gear comprises a gear body (1), gear teeth (2), tooth spaces (3), key grooves (4) and abrasion-resistant titanium alloy layers (5), wherein the outer surfaces of the gear teeth (2) and the outer surfaces of the tooth spaces (3) are covered with the abrasion-resistant titanium alloy layers (5). The abrasion-resistant titanium alloy gear has the advantages that hardness is high, friction coefficients are low, lubricating performance is good, corrosion-resistant performance and abrasion-resistant performance are superior, and noise is low.
Description
technical field [0001] The invention designs a titanium alloy wear-resistant gear, which belongs to a component of a mechanical transmission mechanism. Background technique [0002] Gear is a common mechanical component in the daily production process and is widely used in transmissions, gearboxes, and engines. Traditionally used gears are generally composed of carbon steel, medium carbon alloy, etc. After special treatment, although the gears meet the requirements of the working environment and use, the surface is still not tough enough, wear-resistant, prone to wear, corrosion, and even Broken teeth affect its use. Contents of the invention [0003] The object of the present invention is to make up for the above-mentioned shortcomings and provide a titanium alloy wear-resistant gear. The invention has the advantages of high hardness, low friction coefficient, good lubricating performance, corrosion resistance, good wear resistance, low noise and the like. [0004] The...
