Description

Technical Field

[0002] Currently, in many industrial applications, such as outdoor engineering equipment, shipbuilding, and underwater operation devices, electric cylinders need to operate in humid or even water-stained environments.

[0003] Most existing servo electric cylinders have limited waterproofing capabilities. Ordinary sealing structures are insufficient to effectively prevent water intrusion. Once water enters the cylinder, it can damage critical components such as the motor and lead screw nut assembly, leading to cylinder malfunction, shortening its lifespan, and increasing maintenance costs. Furthermore, even if some electric cylinders possess some waterproofing capabilities, they cannot effectively handle small amounts of water that enter the cylinder body. Long-term accumulation will also affect the normal operation of the electric cylinder, especially ensuring the waterproof seal in the transmission area. Failure to address this promptly can cause rust and damage to transmission components, significantly increasing operating costs. Utility Model Content
