Abstract
A roll shaft for preventing dust from incoming comprises a non-rotatable shaft; bearings are mounted at the upper and lower ends of the non-rotatable shaft; a bearing sealing device is mounted on the upper bearing; a bearing locking device is mounted at the lower end of the non-rotatable shaft; a roll shaft sleeve is mounted on the upper bearing and the lower bearing; a half-shaft head is fixed at the lower end of the roll shaft sleeve by a connecting piece; a grinding roll is mounted on the half-shaft head by the locking device. According to the invention, no gap is provided to allow the peripheral part of the lower end of the roll shaft sleeve to be communicated with the bearings below; no dust is allowed to enter into the bearings from the lower part of the roll shaft; the design can completely and greatly increase the service life of the bearings; daily oiling is not necessary; shutdown is not required; the equipment can run continuously for a long time; the efficiency is increased; the production and maintenance cost is saved; and the labor intensity for workers is reduced.
Description
Technical field
The present invention relates to can need not refuel the long period under a kind of, situation that dust is a lot of abominable in condition of work, and the roll shaft that enters 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 bigger; 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 enter bearing from the slit of the 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 the thing that a kind of Time of expense takes a lot of work and requires 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 present invention takes 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 enters, comprise 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 by connector, by 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 among the present invention 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, roller is thrown away and bull ring generation grinding pressure, 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 roll sleeve of the present invention; dust does not enter 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; 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 is raised the efficiency; save and produce and maintenance cost, alleviate labor strength.

Associated sealing arrangement for bearings is interior labyrinth lid 4 and outer labyrinth lid 3, and they are installed on the upper bearing (metal) 5 successively.
6 times end connections of roll sleeve are bolt.
The lower bearing locking device is a locking nut 8.
Grinding roller 10 locking devices are semiaxis head nut 11.
Roll sleeve 6 lower ends and semiaxis head 9 upper ends be connected to step, be placed with dust-proof cushion (not shown) in the middle of their.
