End is connect with seal cover board, and one end of the seal cover board is connect with the first oil sealing, and the side of the graphite packing is equipped with end cap,
The side of the end cap is connect with apparatus body, and an oiling nozzle, and the oiling are installed after the upper bore of the end cap
One end of nozzle is connect with graphite packing.
It as a kind of optimal technical scheme of the utility model, is screwed in after the seal cover board thread, compresses graphite packing.
As a kind of optimal technical scheme of the utility model, first oil sealing and the second oil sealing coordinate progress with axis
Sealing.
As a kind of optimal technical scheme of the utility model, due to injecting No. 1 lithium saponify inside the oiling nozzle.
The advantageous effect that the utility model is reached is：A kind of associated sealing arrangement for bearings under more dust atmospheres, by end
Lid is tightened using graphite packing, is screwed in after seal cover board thread, and graphite packing, seal cover board inner circle recessing, installation first are compressed
Oil sealing, the second oil sealing and axis cooperation are sealed；On end cap sheath drill after install an oiling nozzle, periodically by oiling nozzle to
No. 1 lithium saponify is injected in end cap, to fill up the gap that graphite packing is formed by abrasion, extends effective Sealing period, it is practical to tie up
During repairing, seal cover board is easily removed, and avoids cost allowance caused by original device damageability is removed.
