Abstract
A roll shaft preventing dust from entering is disclosed, and comprises a non-rotary shaft. Bearings are installed at upper and lower ends of the non-rotary shaft. A bearing sealer is installed on the upper bearing and a bearing locker is arranged at the lower end of the non-rotary shaft. A roll shaft sleeve is arranged on the upper and lower bearings. A half shaft head is fixed at the lower end of the roll shaft sleeve through a connecting piece. A grinding roller is installed on the half shaft head through a locker. In the utility model, no gap communicates the periphery of the lower end of the roll shaft sleeve with the bearings below so that dust cannot enter the bearings completely from the lower part of the roll shaft.. The design can greatly improve the service life of the bearings without filling oil every day and shutdown. The device can work continuously for a long time, thereby improving the efficiency, saving the production and maintenance cost and alleviating the labor intensity of workers.
Description
Technical field
The utility model relates under a kind of, situation that dust is a lot of abominable in condition of work and can need not refuel the long period, and the roll shaft that gets into of a kind of anti-dust that can prolong bearing service life.
Background technology
At present in the disintegrating apparatus of pulverizing the nonmetallic ore field; Raymond mill is that a kind of comminuting matter is wide in variety, output is big, energy consumption is lower and use disintegrating apparatus very widely; Aspect coarse crushing, also seldom there is other disintegrating apparatus can substitute it at present; But it is exactly that the bearing that all needs every day apply oil fat to protect to grind roll shaft can not burn out because of oil-free lubrication that this disintegrating apparatus wherein has outstanding shortcoming; The shortcoming of this design is that roller and perching knife rotate and ore produced dust can splash in the random unrest of roller periphery when rolling and colliding; Dust is easy to get into bearing from the slit of binding site of following oil cap and axle, the lubricating grease of the inside be mixed into can not lubricate greasy filth, if untimely supplemental lubrication fat burns out with regard to being easier to make bearing heating.Though can prolong the service life of a spot bearing like this, be difficult to the service life of bearing surpass one month, moreover the replacing bearing also be a kind of time-consuming thing of taking a lot of work and requiring great effort.
Summary of the invention
For the short shortcoming in bearing service life that overcomes the roll shaft of working under Raymond mill and other adverse circumstances, the measure that the utility model is taked is the rotation with former roller, and promptly axle rotates and bearing sleeve is motionless, changes into axle not rotate, and axle sleeve rotates.
The roll shaft that this anti-dust gets into comprises a not turning cylinder, it is characterized in that; At the two ends up and down of turning cylinder not bearing is installed; Associated sealing arrangement for bearings is installed on upper bearing (metal), bearing locking device is housed, on upper bearing (metal) and lower bearing, roll sleeve is housed in the lower end of turning cylinder not; The roll sleeve lower end is fixed with the semiaxis head through connector, through locking device grinding roller is installed on the semiaxis head.
Associated sealing arrangement for bearings is interior labyrinth lid and outer labyrinth lid, and they are installed on the upper bearing (metal) successively.
Dust cover is equipped with in the upper end of roll sleeve.
End connection is bolt or pin under the roll sleeve.
The lower bearing locking device is nut or pin.
The grinding roller locking device is nut or pin.
Roll sleeve lower end and semiaxis head upper end be connected to step, or connect with flange, be placed with dust-proof cushion in the middle of their.
Not two circular shaft heads above the turning cylinder in the utility model are installed on the Raymond mill beaming roller tray rack; When the beaming roller tray rack rotates the back because the centrifugal force that rotates; Throw roller and bull ring generation grinding pressure away; Roller rotates and turning cylinder is not motionless, and the material that roller scoops up the perching knife that rotates with main shaft is thrown to bull ring and carried out rolling and obtain product.
End periphery communicates with following bearing is seamless under the utility model roll sleeve, and dust has got into not bearing fully from the roll shaft bottom, though dust is also arranged at roll shaft top; But these dust are the floating dust that do not have extruding force, and working environment is more much better than following, according to observing for many years and following the tracks of; The dust atmosphere that does not have extruding in actual use just can solve the problem that spherical bearing advances dust fully with two labyrinth end caps and dust cover sealing, and this design can significantly improve the service life of bearing fully; Do not need refuel every day, need not shut down, but the equipment long time continuous working; Raise the efficiency, save and produce and maintenance cost, alleviate labor strength.
