Abstract
The utility model relates to a sealing structure of a big gear of a ball grinder. The sealing structure of the big gear of the ball grinder comprises sealing felt (1), a pressing plate (2), a sealing gasket (3), a gear cover oil groove (4) and a jackscrew (5). The big gear conducts rotational motion around a center shaft of the big gear. The two ends of the big gear are provided with big gear oil grooves. The sealing gasket (3) is arranged between a gear cover and the gear cover oil groove (4). The gear cover oil groove (4) extends to the position below the big gear oil grooves. The end of the gear cover oil groove (4) is provided with an annular groove in the radial direction. The felt (1) is placed in the annular groove. The pressing plate (2) and the jackscrew (5) are arranged below the annular groove. The sealing structure of the big gear of the ball grinder effectively solves the problems that oil leaks from the big gear, and dust enters the gear cover.
Description
Technical field
The utility model relates to a kind of sealing configuration, especially a kind of Gear of Ball Mill sealing configuration.
Background technique
At present, the Edge-Transmission pebble mill using on market, its gearwheel sealing principal mode mainly contains radially packing seal, end face packing seal, but due to the long term wear of filler and gear sealing, between filler and sealing surface, form gap and cause leakage of oil, both wasted lubricant oil, and also had a strong impact on environment, to such an extent as to gearwheel leakage of oil becomes the problem that never has fine solution.
Model utility content
In order to overcome above-mentioned deficiency of the prior art, solve the pebble mill sealing problem of gearwheel, thereby solve gearwheel leakage of oil, prevent that dust from entering the problems such as gear house inside.The utility model proposes a kind of new solution.
A kind of Gear of Ball Mill sealing configuration, described sealing configuration comprises sealing felt (1), pressing plate (2), sealing gasket (3), gear cover oil groove (4), jackscrew (5), described gearwheel (1) rotates around its axis, its two ends are provided with gearwheel oil groove, between gear cover and gear cover oil groove (4), have sealing gasket (3), gear cover oil groove (4) extends to gearwheel oil groove below, is radially having a circular groove in its end, in circular groove, put felt (1), it is arranged with pressing plate (2) and jackscrew (5).
Accompanying drawing explanation
Fig. 1 is the utility model Gear of Ball Mill sealed structural representation.
Wherein, sealing felt (1), pressing plate (2), sealing gasket (3), gear cover oil groove (4), jackscrew (5).
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
As Fig. 1, a kind of Gear of Ball Mill sealing configuration, described sealing configuration comprises sealing felt (1), pressing plate (2), sealing gasket (3), gear cover oil groove (4), jackscrew (5), described gearwheel (1) rotates around its axis, and its two ends are provided with gearwheel oil groove, between gear cover and gear cover oil groove (4), has sealing gasket (3), gear cover oil groove (4) extends to gearwheel oil groove below, radially having a circular groove in its end, putting felt (1) in circular groove, it is arranged with pressing plate (2) and jackscrew (5).
Its working principle is as follows: gearwheel two ends carry oil groove, between gear cover and gear cover oil groove, has sealing gasket, and gear cover oil groove extends to gearwheel oil groove below, and radially there is being a circular groove end, puts felt in circular groove, under have pressing plate and jackscrew.In gearwheel turning course, long-pending lubricant oil is thrown to gear cover inwall by gearwheel oil groove, and the oil on inwall flows on gear cover oil groove, and gear cover oil groove extends to below gearwheel oil groove, can collect the lubricant oil that all gear covers flow down, then flow to fuel tank along gear cover oil groove.Felt and pressing plate adopt flexible sealing, can prevent that external dust from entering gear cover.Jackscrew can be adjusted at any time according to the abrasion condition of felt, guarantees felt and gearwheel laminating closely.
Technological points of the present utility model is:
A, the utility model design gear cover oil groove positions at radially inner ring of gearwheel oil groove, extend under gearwheel oil groove, can collect all lubricant oil that gearwheel throws away.Simple in structure, without leakage of oil point.
B, gear cover oil groove are with bolts, are out of shape littlely, and install and adjust is convenient.
C, jackscrew can be adjusted at any time according to the abrasion condition of felt, guarantee felt and gearwheel laminating closely.
The utility model solves the pebble mill sealing problem of gearwheel, thereby solves gearwheel leakage of oil, prevent that dust from entering the problems such as gear house inside.
The above is only the utility model preferred implementation; should be understood that; for the member of ordinary skill of the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
