Abstract

The invention belongs to the field of mechanical conveying of corrosive liquid chemicals, and particularly relates to an anti-corrosion nested type gear and a gear pump filling machine. The anti-corrosion nested type gear comprises an inner tooth ring and an outer tooth ring, wherein the outer tooth ring is nested at the outer part of the inner tooth ring; an axial hole is formed in the center of the inner tooth ring; multiple first tooth threads are arranged on the outer circumferential surface of the outer tooth ring; the outer tooth ring is made of anti-corrosion plastic. The anti-corrosion nested type gear disclosed by the invention has the beneficial effects that not only can a gear be simply and efficiently disassembled, assembled and replaced, but also a working environment for conveying the corrosive liquid chemicals by the gear pump filling machine can be well adapted, and meanwhile, the service life of the gear is prolonged.

Description

technical field [0001] The invention belongs to the field of mechanical transportation of corrosive liquid chemicals, in particular to a nested corrosion-resistant gear used in a gear pump filling machine. Background technique [0002] Gears are an important basic part of mechanical equipment and the core component of many electromechanical products. As far back as 300 B.C., ancient Greek philosopher Aristotle had just set forth the problem of transmitting rotary motion with bronze or cast iron gears in "Mechanical Problems". With the rapid development of industrial technology, gear transmission has become the most widely used transmission device, and the main transmission components of most mechanical complete sets of equipment are gear transmission. Since my country's reform and opening up, the development of gear technology and products has also advanced by leaps and bounds. The gear industry has become the largest industry in China's mechanical basic parts. [0003] Th...
