Description
Technical field
The utility model relates to a kind of grinding roller of wheat flour-milling assembly apparatus, also relates to the grinding roller axle of this grinding roller assembly apparatus simultaneously.
Background technology
Raymond mill mainly is made up of main frame, analytical engine, air blast, finished product cyclone separator, plumbing installation, and wherein main frame comprises frame, air intake spiral case, perching knife, grinding roller assembly, bull ring, case and motor.During work, perching knife is thrown material between grinding roller assembly and the bull ring, serves as abrasive material by material, by the centrifugal force that the grinding roller that runs up produces the material extruding is pulverized.The grinding roller assembly comprises grinding roller axle, grinding roller core and grinding roller skin, the grinding roller axle is installed in the cavity of grinding roller core, between grinding roller axle and grinding roller core, be provided with and cooperate bearing shell with the grinding roller axle, the grinding roller leather sheath is contained on the grinding roller core, described grinding roller core outer surface has certain conicity, and the inner surface of grinding roller skin has the conicity that cooperates with the grinding roller core outer surface.Inside at the grinding roller axle is provided with lubricant reservoir, be arranged at intervals with two oil outlets that are communicated with lubricant reservoir on the grinding roller axle with on the surface that bearing shell is rotatably assorted, described two oil outlets are all opened in the same side of grinding roller axle, are connected with straight line list oil-way between two oil outlets.During work; lubricating oil in the lubricant reservoir enters between grinding roller axle and the bearing shell through oilhole; play lubricated effect; but because have only 10 microns gap between grinding roller axle and the bearing shell; when the grinding roller assembly runs up; lubricating oil in the lubricant reservoir of grinding roller axle can not well pass through the oil storage cavity of original design; oil outlet and single oil-way enter between grinding roller axle and the bearing shell; lubricant effect is very poor; friction ratio is bigger between grinding roller axle and the bearing shell; cause the phenomenon of locking shutdown of grinding roller axle and lubricant pollution material easily; so not only grinding roller axle well damage has also influenced normal use.
The utility model content
The purpose of this utility model provides a kind of grinding roller of wheat flour-milling assembly apparatus, adopt this grinding roller assembly apparatus can effectively solve in original technology the technical problem of lubricant effect difference between the grinding roller axle and bearing shell, the utility model also provides the grinding roller axle in a kind of above-mentioned grinding roller of wheat flour-milling assembly apparatus simultaneously.
The technical scheme of the grinding roller axle of a kind of grinding roller of wheat flour-milling assembly apparatus of the utility model is: a kind of grinding roller axle of grinding roller of wheat flour-milling assembly apparatus, comprise a body, this body interior is provided with the oil storage cavity, on described axle body and side face that bearing shell is rotatably assorted, be provided with first oil outlet and second oil outlet that is connected with described oil storage cavity, first helical oil groove connection that described first oil outlet and second oil outlet are provided with by threaded shaft body peripheral surface.
Described first oil outlet and second oil outlet are arranged at the same side of a body, opposite side at the axle body also is provided with the 3rd oil outlet and the 4th oil outlet, and described the 3rd oil outlet and the 4th oil outlet are communicated with by second helical oil groove that threaded shaft body peripheral surface is provided with.
The grinding roller axle axle body of the utility model grinding roller of wheat flour-milling assembly apparatus is provided with first oil outlet and second oil outlet that is connected with the oil storage cavity with the side face that bearing shell is rotatably assorted, and two oil outlets are connected by the helical oil groove that is arranged on the body peripheral surface.Adopt helical oil groove, covert increase the lubricated area of lubricating oil in the unit interval, strengthened lubricant effect.And when lubricating oil from the oil storage cavity after first oil outlet and second oil outlet enter into helical oil groove, when grinding roller runs up, utilize the fast rotational between bearing shell and the grinding roller axle, lubricating oil is promoted from the bottom up through helical oil groove, avoided working as lubricating oil more after a little while, the petrol starvation on the top of grinding roller axle and bearing shell has reduced the friction of grinding roller axle and bearing shell.
Increase the 3rd oil outlet and the 4th oil outlet, further increased the oil pump capacity in the unit interval, the 3rd oil outlet and the 4th oil outlet are communicated with by second helical oil groove, increased the lubricated area of interior grinding roller axle of unit interval and bearing shell mating surface.
The technical scheme of a kind of grinding roller of wheat flour-milling assembly apparatus of the utility model is: a kind of grinding roller of wheat flour-milling assembly apparatus, comprise the grinding roller axle, this grinding roller axle comprises a body, this body interior is provided with the oil storage cavity, on described axle body and side face that bearing shell is rotatably assorted, be provided with first oil outlet and second oil outlet that is connected with described oil storage cavity, first helical oil groove connection that described first oil outlet and second oil outlet are provided with by threaded shaft body peripheral surface.
Described first oil outlet and second oil outlet are arranged at the same side of a body, opposite side at the axle body also is provided with the 3rd oil outlet and the 4th oil outlet, and described the 3rd oil outlet and the 4th oil outlet are communicated with by second helical oil groove that threaded shaft body peripheral surface is provided with.
On the grinding roller of wheat flour-milling assembly apparatus, use above-mentioned grinding roller axle, strengthened the oil pump capacity of oil storage cavity in the grinding roller axle, and can effectively utilize lubricating oil behind the employing helical oil groove, make and obtain enough lubricating between grinding roller axle and the bearing shell, thereby prolonged the service life of grinding roller axle, prolong the maintenance period of grinding roller assembly, improved production efficiency.
