AI Technical Summary
Existing electric gate track rollers are prone to depletion of lubricating grease or increased mechanical friction due to rain, high temperature and dust in outdoor environments, resulting in increased running resistance and damage to the gate structure and motor.
Design an oiling device for an electric door track roller, including a sealed square tube, an oil storage chamber, an oiling hole, a hollow screw plug, a hollow shaft, a nut, and an oil leakage hole. Lubricating oil is added through the oiling hole and the lubricating oil flows automatically into the bearing and wheel using gravity. The device is combined with a cover and a sealing ring to prevent rainwater and dust from entering.
It enables long-term operation of the track rollers, reduces the frequency of damage, extends service life, maintains the lubrication of bearings and wheels, and prevents rain and dust from affecting them.
