Abstract
The utility model discloses a grinding roller assembly device of a hanging roller type mill, which comprises a grinding roller shaft, a core sleeve, a protecting sleeve, a cross arm head and an oil immersing felt, wherein the grinding roller shaft is an optical shaft of which the lower end is provided with a flange so as to fully solve the danger that a grinding roller falls off, the oil immersing felt is added between the lower end surface of the cross arm head and the upper end surface of the core sleeve, the protecting sleeve forms screw connection with the cross arm head and the side wall of the cross arm head is provided with an oil plug. The grinding roller assembly device has the advantages of simple structure, good sealing and lubricating property, long service life, convenient maintenance and high efficiency.
Description
The utility model relates to a kind of Suspension roller grinder, especially relates to a kind of grinding roller assembly apparatus of Suspension roller grinding machine.
At present, the Suspension roller grinding machine that generally use in China middle-size and small-size magnesia ore deposit, talcum ore deposit etc., in its grinding roller assembly apparatus, central shaft is upper coarse and lower fine multistage multidiameter, sheath is uncontrollable fixed form, and lubricant passage way system is unreasonable, and the lubricating oil memory space is little, the patent No. is the grinding roller assembly that ZL97205318.2 provided, an example that comes to this.Its outstanding defective is: the grinding roller axle of heavy-duty low-speed running stressed unreasonable, the shaft shoulder of multidiameter partly has bigger stress to concentrate, thereby often there is the off-axis phenomenon to take place, the following wearing piece that supports grinding roller and mobile again with grinding roller lower end thread connection, thereby easily loosening, cause coming off of grinding roller and whole mobile.Cross-arm head and grinding roller axle upper end and horizontal axis tam all adopt the plunging assembling.Assembling like this, maintenance are all inconvenient.In case matching loose, necessary renewal part causes the equipment paralysis.In addition, its sheath can not be given full play to the effect of regulate the powder gap, and sealing effectiveness is bad, the mode of grinding roller axle centre bore oiling, and lubricating oil does not arrive attrition surface, causes dry grinding, and shutdown maintenance also influences the service efficiency of complete machine.
The purpose of this utility model is to provide a kind of service life that can prolong grinding roller axle and brasses, and sealing reaches lubricated good, easy to maintenance, thereby can improve the grinding roller assembly of complete machine production efficiency.
The purpose of this utility model is achieved in that the grinding roller axle with upper coarse and lower fine multistage ladder form changes the optical axis that the lower end has flange into, corresponding its assembling mode also changes in the core retainer plate of packing into from lower to upper, like this, the force part of grinding roller axle has not just had stress to concentrate, frangibility not, and since the improvement of the structure of grinding roller axle, the annular oil cavity space enlargement, increase oil reserve, guaranteed to have for a long time enough oil lubrication; Sheath and cross-arm head can be adjusted the into minimum clearance of dust by thread connection; Between the upper surface of the lower surface of cross-arm head and core retainer plate, be added with the immersion oil felt,, reach the sealing effectiveness of the best by adjusting the gap of sheath and mobile; Sidewall at the cross-arm head is provided with a plug cock, is oil filler point in the plug cock, and lubricating oil injects immersion oil felt and reinforced seal through the cavity of cross-arm head and the branch food tray in the cavity, like this, has solved the problem of last attrition surface dry grinding.
The grinding roller assembly that adopts the utility model to provide, good sealing effect, long service life, simple in structure, easy to maintenance, raise the efficiency.
Below in conjunction with accompanying drawing preferred forms of the present utility model is elaborated.
This accompanying drawing is the profile of grinding roller assembly.
Grinding roller axle 1 has the optical axis of flange for the lower end, pack into from lower to upper in the core retainer plate 2, the medial surface on core retainer plate 2 tops and grinding roller axle 1 form an annular shoe cream room 3, lubricating oil in the annular shoe cream room 3 passes through the oilhole of grinding roller axle 1 and the constantly downward attrition surface of oil duct of brasses injects lubricating oil, guarantees enough the lubricating of attrition surface down; Between the upper surface of the lower surface of cross-arm head 4 and core retainer plate 2, be added with immersion oil felt 7; Sheath 9 and cross-arm head 4 thread connection by adjusting the gap of sheath 9 and immersion oil felt 7, reach the optimal seal effect; Sidewall at cross-arm head 4 is provided with a plug cock 5, in the plug cock 5 is oil filler point, lubricating oil injects immersion oil felt 7 and reinforced seal 8 through the cavity of cross-arm head 4 and the branch food tray 6 in the cavity, guarantees lubricating of last attrition surface that the upper surface of immersion oil felt 7 and lining 2 forms.
