Technical solution of the present utility model: a kind of movable casting iron machine cantilever rollers hermetically-sealed construction, comprise major axis, spacer, bearing, roller and gland, described roller is arranged on major axis end by bearing and spacer; On described roller inner face, there is seal groove in annular external seal groove and annular, and in annular, seal groove is positioned at roller wheelboss inner hole periphery, on described roller wheelboss inner hole inwall, there is annular seal groove, and annular seal groove is in bearing inner face and annular between seal groove; In described annular external seal groove, be filled with airtight and watertight padding I, in annular, in seal groove, be filled with contact oil seal, annular seal groove is filled with airtight and watertight padding II; Described spacer has annular boss on outer face, and annular boss embeds and in annular external seal groove, airtight and watertight padding I, contact oil seal is separately fixed in annular external seal groove and annular in seal groove; The end of described major axis is set with baffle ring, and baffle ring is embedded in the annular groove of roller outer face the outer face sealing of bearing; Described roller is provided with gland on outer face, and between gland and roller outer face, passes through to install annular gasket seal.
Described airtight and watertight padding I, airtight and watertight padding II are immersion oil asbestos packing.
Described contact oil seal is J type outside framework oil seal, and is interference fit with the interior internal diameter of seal groove of annular and the external diameter of major axis.
Between described baffle ring and bearing outer face, there is oil storage gap, after installation, by bearing pin pin, keep off.
The advantage the utlity model has and effect:
1, the utility model consists of multiple tracks different sealing structure, foreign matter, impurity are carried out to effectively thoroughly shutoff, can prevent that lubricating grease from leaking simultaneously, guarantee that roller lubricating grease within service life does not lose, do not pollute, do not need secondary oiling, rotate flexibly, extended to greatest extent the service life of roller.
2, the multiple seal that the utility model adopts is easily purchased, and cost is low, durable in use, has not only guaranteed the quality of hermetically-sealed construction, and has reduced the cost of hermetically-sealed construction.
3, the utility model is simple in structure, and reliability is high, has reduced pig machine operating maintenance cost, has extended the service life of pig machine.
