Abstract
The utility model relates to a gear shaft of a spiral classifier in the equipment field of spiral classifiers, two cylindrical double-row rolling bearings are respectively fixedly arranged at a shaft head at each end of the gear shaft, and a shaft sleeve is fixedly arranged on the outer wall of the shaft head at each end of the gear shaft; and the outer wall is positioned between the two cylindrical double-row rolling bearings. With the gear shaft of the spiral classifier, the change of a gear clearance between a big gear and a corresponding small gear on the gear shaft can be effectively avoided, and the operation loads of the gear shaft and gears can be stabilized, so that the occurrence of phenomenon of rupture of the gear shaft and the gears is avoided.
Description
[technical field]
The utility model relates to the spiral classifier apparatus field, especially relates to a kind of spiral classifier gear shaft that can reduce load.
[background technique]
At present, the spiral classifier of in industrial ore dressing, using always, as the working principle of 2FG-3000 spiral classifier is exactly solid particle size and proportion difference after utilizing ore or material broken, so stressing conditions difference in liquid and sinking velocity difference, therefore the fine granular materials that will be suspended in the classification trough inner water is discharged by overflow, the coarse granule material is deposited in bottom land, and is discharged by the coarse sand mouth, thereby the realization material is pressed proportion or the continuous a kind of classifying equipoment that separates of size of grain; In conjunction with the accompanying drawings 1, in use find, the bearing shell supporting is adopted at the gear shaft two ends of 2FG-3000 spiral classifier drive part, it is sliding bearing, and do not have the oil chamber in the structure of bearing shell, therefore very easily cause the loss of lubrication on the gear shaft, increase gradually thereby gear shaft is in use loaded, and then cause gear shaft and bearing shell to produce wearing and tearing, influence its working life; Simultaneously because the wearing and tearing of gear shaft and bearing shell, caused on the gear shaft gearwheel and and the small gear of gearwheel engagement between gear clearance be affected and change; The variation of gear clearance has caused the operating load of gear shaft and gear suddenly big or suddenly small again, thereby the phenomenon that gear shaft or gear breaking very easily occur, and then cause the decline of operation rate, and caused the increase of enterprise's beneficiation cost, bring extra economic burden to ordinary production.
[summary of the invention]
In order to overcome the deficiency in the background technique, the utility model provides a kind of spiral classifier gear shaft, described gear shaft can effectively avoid gearwheel on the gear shaft and the gear clearance between the small gear to change, and has stablized the operating load of gear shaft and gear.
For achieving the above object, the utility model adopts following technological scheme:
A kind of spiral classifier gear shaft, the two ends spindle nose of described gear shaft is installed with two cylinder double-row bearings respectively, and the outer wall of the every end spindle nose of gear shaft between two cylinder double-row bearings is installed with axle sleeve.
Described spiral classifier gear shaft, described cylinder double-row bearing and gear shaft are interference fit.
Described spiral classifier gear shaft, described axle sleeve and gear shaft are interference fit.
Described spiral classifier gear shaft, described half bush wall thickness is not more than the thickness of cylinder double-row bearing inner ring.
Owing to adopt aforesaid technological scheme, the utlity model has following beneficial effect:
Spiral classifier gear shaft described in the utility model, can effectively avoid the gearwheel on the gear shaft to change with gear clearance between the corresponding small gear, stablize the operating load of gear shaft and gear, thereby avoided the phenomenon of gear shaft or gear breaking to take place.
[description of drawings]
Fig. 1 is the schematic representation of existing gear shaft;
Fig. 2 is the schematic representation of gear shaft described in the utility model;
Among the figure: 1, gear shaft; 2, bearing shell; 3, gearwheel; 4, small gear; 5, cylinder double-row bearing; 6, axle sleeve.
[embodiment]
Can explain the utility model in more detail by the following examples, open the purpose of this utility model is intended to protect all changes and improvements in the utility model scope, and the utility model is not limited to the following examples;
2 described spiral classifier gear shafts in conjunction with the accompanying drawings, the two ends spindle nose of described gear shaft 1 is installed with two cylinder double-row bearings 5 respectively, the shaft head that is gear shaft 1 each end replaces bearing shell 2 by two cylinder double-row bearings 5, gear shaft 1 is reached does not have the wearing and tearing and the little purpose of loading, and avoided on the gear shaft 1 gearwheel 3 and and the small gear 4 of gearwheel 3 engagements between gear clearance be affected and change; Simultaneously, in order to increase by 5 width that can carry of two cylinder double-row bearings of gear shaft 1 every end, on the outer wall between two cylinder double-row bearings 5, be installed with axle sleeve 6 at gear shaft 1 every end spindle nose, thereby can select corresponding axle sleeve 6 as required; In addition, in order further to reduce the load of gear shaft 1, described axle sleeve 6 thickness can be made as the thickness that is not thicker than cylinder double-row bearing 5 inner rings.
Implement spiral classifier gear shaft described in the utility model, on an end spindle nose of gear shaft 1, first cylinder double-row bearing 5 interference fit are filled to suitable position, and then the interference fit corresponding axle sleeve 6 of packing into, refill second cylinder double-row bearing 5 at last, the axle sleeve 6 after the installation closely is fixed between two cylinder double-row bearings 5; After all installing, the two ends of gear shaft 1 spindle nose promptly can come into operation.
Carefully not stating in the above content is prior art partly, does not state so run business into particular one.
Learn by test, under equal conditions, adopt the equipment of spiral classifier gear shaft described in the utility model can effectively reduce the load of equipment, make the running rate of equipment improve 0.5%, thereby can be at the ore of about 600 tons of multiprocessings in every month, create surplus in the of 10 ten thousand economic benefit for the user more.
