AI Technical Summary
Technical Problem
The gap between the gearbox spindle and the spacer ring allows external moisture to easily enter, leading to corrosion of the sealing components and affecting the operation and lifespan of the equipment.
Method used
A gearbox spindle sealing and moisture-proof device was designed. It is fixed on the spindle by a first arc-shaped platform and a second arc-shaped platform, and the sealant is heated by a heating component to quickly solidify and form a sealing and moisture-proof layer, sealing the gap between the spacer ring and the spindle.
Benefits of technology
It improves the sealing effect, prevents moisture from entering the gearbox, avoids corrosion of sealing components, extends the service life of the equipment, and reduces maintenance costs.

Abstract
The utility model provides a kind of gear box main shaft sealing moisture-proof device, including first arc platform and second arc platform, the first arc platform and the second arc platform one end rotationally connected, the other end of the first arc platform and the second arc platform is connected with locking piece, the position of the first arc platform and the second arc platform is fixed on main shaft by locking piece and is applied sealant;Heating assembly is provided on the first arc platform and the second arc platform, and heating assembly is used to heat sealant, so that the sealant coated on main shaft is condensed to form sealing moisture-proof layer.The device is heated quickly by heating assembly to sealant, so that it is quickly solidified on the position of main shaft located at distance ring, the gap between distance ring and main shaft is blocked, the sealing property between main shaft and distance ring is improved, the sealing effect is improved, water vapor etc. are prevented from entering gear box through the gap, and the sealing components in gear box and main shaft are caused corrosion.
