Externally mounted electric roller can not be separated from lubrication
1. The edible oil for head lubrication is mainly used to lubricate the gear, rolling bearing and other transmission mechanisms and cool the motor at the same time, because its structural characteristics are that the head rotates and the oil scraper takes up the oil and continuously drips it on the gear and rolling bearing, so the lubrication standard is better and the oil is adequately cooled at the same time, Therefore, the lubricating oil of the reducer can completely reach the edible oil of the electric cylinder, but the electromagnetic coil of the immediately cooled motor has higher requirements on the stability energy and purity of the oil because the oil enters the internal structure.
2. The oil filling and changing of the head is that the new electric drum is generally out of oil, so it is necessary to carefully check the oil supply as required immediately before the trial operation. The oil change period is more than half a month during the running in time, and the oil shall be added and changed immediately according to the application conditions.
Whether the external electric drum is oil-cooled or oil variable, the lubricating hydraulic oil in the drum cools the motor and also acts as the lubricant for the gear and rolling bearing to release the heat caused by the motor and harmonic current gear transmission mechanism immediately. The advantages and disadvantages of heat removal endanger the oil temperature, and the oil temperature affects the oil viscosity, which endangers the oil slick on the gear teeth and the service life of the gear.
Basic structure principle of VD external electric roller
Principle: the motor is externally connected with the rubber support. According to the input shaft, the driving force is transmitted to the internal structure of the drum to promote an open toothed gear and a pair of internal meshing gears to slow down the drum. When the drum rotates, it cools and lubricates the intercalated sliding gear and rolling bearing.
