High life oiling idler roller
High-life oil-injected idler is an oil-injected idler. The utility model is an idler for a belt conveyor. It is characterized in that one on the outside surface of the bearing seat at one end of the idler and at a symmetrical radius of the same diameter. An oil delivery channel, one of which is semi-open, communicates vertically with the thin oil passage in the bearing housing, the other is directly connected, and communicates with the oil delivery passage on the other bearing housing through a bridge-type metal or plastic oil pipeline, and It is also in vertical communication with the thin oil passage in the seat. Corresponding to the two oil delivery passages, two oil injection holes of equal diameter are opened at the same orientation and radius position of the outer sealed end cover. The combination of the seal end cover and the outer side of each bearing seat adopts a labyrinth gap oil seal method. The combination of the seal end cover and the roller shaft is a tight fit, which is stationary with the shaft.
The high-life oiling idler roller is convenient for oiling, has low processing and manufacturing costs, has good lubrication and sealing effects, does not waste oil, and protects the idler roller for a long service life.
