Abstract
The utility model discloses a vertical mill grinding roller air sealing piece which comprises a grinding roller shaft, a hydraulic pull rod head and a bearing end cover. The opposite sides of the hydraulic pull rod head and the bearing end cover are fixedly provided with a convex sealing piece and a concave sealing piece which are matched with each other respectively. The matching faces of the convex sealing piece and the concave sealing piece are both oblique faces, a gap is formed between the matching faces of the convex sealing piece and the concave sealing piece and is sealed by smearing epoxy resin. The vertical mill grinding roller air sealing piece is of a split type sealing structure, the air locking effect is guaranteed, dust is prevented from entering a framework oil seal on the outer side of a bearing, the effect guaranteeing the bearing to operate safely in a long term is achieved, and mounting and dismounting are very convenient.
Description
Technical field
The utility model relates to the part field of Vertical Mill, specifically a kind of grinding roller of vertical mill air seals.
Background technique
As energy-saving and cost-reducing novel milling equipment, Vertical Mill is applied to cement industry in large quantities.As the vitals of numerous model Vertical Mills, the air seals in its grinding roller outside needs often to change because easily wearing and tearing, and in prior art, its air seals is integral seal structure, has brought trouble to installation and removal.
The method for dismounting of Sealing is: 1. grinding roller is fallen on mill, hydraulic cylinder pressure relief, ensures that hydraulic pressure draw-bar head, toggle are all in the state of not stressing; 2. dismantle the bearing pin that is connected of hydraulic pressure draw-bar head and toggle, the connecting bolt of dismounting hydraulic pressure draw-bar head and hydraulic pressure draw-bar, to remove hydraulic pressure draw-bar head and outside being connected; 3. dismantle hydraulic pressure draw-bar train head lid, lock collar, utilize Hydraulic power tools or increase self-control assistant tool joint shaft bearing is exited from shaft of grinding roller in the lump together with tapered sleeve, hydraulic pressure draw-bar head is exited from roll shaft.Installation steps are contrary with above-mentioned demounting procedure.
There are several difficulties in above-mentioned dismantlement work: be 1. connected bearing pin with hydraulic pressure draw-bar head high because grinding the interior a large amount of coal dusts, operating ambient temperature of existing for toggle, cause and cannot dismantle smoothly, sometimes need destructiveness to cut off, and the work of cutting off will consume the long period and will make or buy spare part; 2. as there are the gap or the wearing and tearing that do not meet design in tapered sleeve and shaft of grinding roller, and hydraulic fluid leak causes oil hydraulic pump oil cannot reach tapered sleeve and exits pressure, and hydraulic pressure draw-bar head cannot exit, thereby causes changing.
Model utility content
The purpose of this utility model is to provide a kind of grinding roller of vertical mill air seals; for split type sealing configuration, ensureing lock wind effect, prevent that dust from entering the outside framework oil seal in bearing outside; when playing the effect of the long-term safe operation of protection bearing, be easy for installation and removal.
The technical solution of the utility model is as follows:
A kind of grinding roller of vertical mill air seals, include shaft of grinding roller, hydraulic pressure draw-bar head and bearing (ball) cover, it is characterized in that: described hydraulic pressure draw-bar head is installed with respectively the male seal part and the spill Sealing that match in a relative side with bearing (ball) cover, the fitting surface of described male seal part and spill Sealing is respectively inclined-plane, and between the fitting surface of male seal part and spill Sealing, has gap and by smearing epoxy sealing.
Described grinding roller of vertical mill air seals, is characterized in that: the gap between the fitting surface of described male seal part and spill Sealing is 0.5 ~ 1.0mm.
The beneficial effects of the utility model:
The utility model is split type sealing configuration, has both ensured lock wind effect, has prevented that dust from entering the outside framework oil seal in bearing outside, has played the effect of the long-term safe operation of protection bearing, mounts and dismounts very convenient again.Be embodied in following some:
(1), simplify: the dismounting link of having omitted large workload, after protruding, the spill that directly gouge or gas cutting need to be dismantled seals, split type new product is installed, male seal (utilizing inner hexagon spanner) is first installed when installation, spill sealing (outside connecting bolt) is then installed;
(2), save time: integral seal change all spare parts on deck, in zero accident situation, generally need 16～24h, connect as run into bearing pin, tapered sleeve, joint shaft bearing move back unload occur unexpected, the time is unable to estimate, when serious, cannot change, split type protruding, spill sealing of the present utility model completely can complete more and change jobs in 16h, and the replacing time is within controlling;
(3), cost saving: integral seal is changed in the time of dismounting joint shaft bearing, needs crane or Manual hoisting holding tool to coordinate, and has produced extra lifting cost use, and split type protruding, recessed sealing of the present utility model is changed without this expense.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
Referring to Fig. 1, a kind of grinding roller of vertical mill air seals, include shaft of grinding roller 1, hydraulic pressure draw-bar head 2 and bearing (ball) cover 3, hydraulic pressure draw-bar head 2 is installed with respectively the male seal part 4 and the spill Sealing 5 that match in a relative side with bearing (ball) cover 3, the fitting surface of male seal part 4 and spill Sealing 5 is respectively inclined-plane, and between the fitting surface of male seal part 4 and spill Sealing 5, has gap and by smearing epoxy sealing.
In the utility model, the gap between the fitting surface of male seal part 4 and spill Sealing 5 is 0.5 ~ 1.0mm, to ensure locking wind effect, prevents that dust from entering the outside framework oil seal in bearing outside, and plays the effect of the long-term safe operation of protection bearing.
Claims (2)
1. a grinding roller of vertical mill air seals, include shaft of grinding roller, hydraulic pressure draw-bar head and bearing (ball) cover, it is characterized in that: described hydraulic pressure draw-bar head is installed with respectively the male seal part and the spill Sealing that match in a relative side with bearing (ball) cover, the fitting surface of described male seal part and spill Sealing is respectively inclined-plane, and between the fitting surface of male seal part and spill Sealing, has gap and by smearing epoxy sealing.
2. grinding roller of vertical mill air seals according to claim 1, is characterized in that: the gap between the fitting surface of described male seal part and spill Sealing is 0.5 ~ 1.0mm.
