Problems solved by technology

[0005] In the existing technology, the main problems of gears in our country are low precision and low production efficiency. Due to the heat generated by the friction of the gear material with the gear at high temperature, the wear resistance of the gear is further reduced, resulting in a short service life.
Among them, the problem of short service life is particularly prominent

Abstract

The invention provides a high-temperature-resistant and wear-resistant gear and a preparation method thereof. The high-temperature-resistant and wear-resistant gear is prepared from the following materials in parts by mass: 30-40 parts of aluminum alloy powder, 15-20 parts of NiCrBSi powder, 20-30 parts of polybutylene terephthalate, 10-15 parts of ZrB, 5-10 parts of a carbonized cubic crystal material, 3-5 parts of glass fibers, 8-10 parts of nano calcium carbonate, 5 -15 parts of bis (hydrogenated tallow alkyl) dimethyl quaternary ammonium bentonite salt, 10-18 parts of zinc stearate and 4-9 parts of tetraethoxysilane. Nano calcium carbonate with hydroxyl functional groups is obtained after nano calcium carbonate is modified through tetraethoxysilane, then the nano calcium carbonate is combined with polybutylene terephthalate to form a core-shell structure, and then the core-shell structure is doped with glass fibers in the presence of a bis (hydrogenated tallow alkyl) dimethyl quaternary ammonium bentonite salt solution, so that the high temperature resistance and wear resistance of the finally formed gear material are improved.

Description

technical field [0001] The invention belongs to the technical field of gear preparation, and in particular relates to a high-temperature-resistant and wear-resistant gear and a preparation method thereof. Background technique [0002] Humans have a long history of inventing and applying gears. Dating back to the distant times before BC, the important role and significance of gears as important mechanical transmission components is self-evident. According to historical records, 2200 years ago, in ancient China, gears were widely used. The bronze gear unearthed in Shanxi, my country is the oldest gear discovered so far. As a guide car reflecting the achievements of ancient science and technology, it is a mechanical device with a gear mechanism as its core. In addition, Archimedes, the ancient Greek philosopher, also explained the problem of using bronze gears to transmit rotary motion in "Mechanical Problems". Various gear machines have also appeared successively afterwards...
