Worm gear of grain packing machine for processing omega-3 fish oil soft capsules

Abstract

The invention discloses a worm gear of a grain packing machine for processing omega-3 fish oil soft capsules. The worm gear consists of the following raw materials in parts by mass: 20-25 parts of tin bronze, 30-35 parts of aluminum bronze, 16-20 parts of grey cast iron, 8-10 parts of aliphatic polyketone, 9-15 parts of epoxy resin, 13-15 parts of chromium diboride, 18-20 parts of calcium hexaboride, 22-25 parts of tantalum carbide, 9-16 parts of vanadium carbide, 7-12 parts of magnesium oxide, 9-15 parts of magnesium hydroxide and 16-20 parts of molybdenum disulfide. The worm gear of the grain packing machine for processing the omega-3 fish oil soft capsules has relatively high strength, corrosion resistance and excellent casting property.

Description

technical field [0001] The invention relates to a worm wheel of a granular packaging machine for processing omega-3 fish oil soft capsules. Background technique [0002] Worm gears are commonly used to transmit motion and power between two interleaved shafts. The worm gear and the worm are equivalent to the gear and the rack in their middle plane, and the worm is similar in shape to the screw. If you want to get a larger gear reduction ratio, you need to use a worm gear. Worm gears typically have a gear reduction ratio of 20:1, sometimes as high as 300:1 or greater. Many worm gears have an interesting property not found in other gear sets: the worm can easily turn the gear, but the gear cannot turn the worm. This is because the lugs on the screw are so shallow that friction between the gear and the screw keeps the screw in place when the gear tries to turn it. The worm transmission is equivalent to the screw transmission, which is a multi-teeth meshing transmission, so t...

AI Technical Summary

Problems solved by technology

When the worm gear meshes and drives, the relative sliding speed between the meshing gear teeth is large, so the friction loss is large and the efficiency is low

On the other hand, the relative sliding speed causes severe wear and heat on the tooth surface. In order to dissipate heat and reduce wear, more expensive materials with better anti-friction and anti-wear properties and good lubrication devices are often used, so the cost is higher.

[0003] At present, the existing worm gear has low structural strength, is not corrosion-resistant, and is inconvenient to cast
