Abstract
The utility model relates to a roller, which comprises a roller body and a rubber layer 2 coated on the outer surface of the shaft body. The utility model is characterized in that the arc surface of the rubber layer 2 is provided with screw threads 3 with different spiral directions. The utility model has the advantages that structure is reasonable, the phenomena of the deviations of a conveyor belt or a circulation type filter press belt during work can be effectively prevented, work efficiency can be enhanced, and working quality can be improved.
Description
The utility model is engineering goods, a kind of more precisely beaming roller that cooperates with line belt or strainer layer.
The known beaming roller that cooperates with line belt or circulating filter-pressing strap, all adopt the roll body of smooth surface, though easy to process, cost is low, usually cause in the course of the work with and roller between skew (being commonly called as sideslip), cause that workmanship descends, efficient reduces.
The purpose of this utility model is: at the deficiencies in the prior art, provide a kind of beaming roller that can overcome deviation phenomenon.
The beaming roller that the utility model provides comprises axis body and the rubber layer that is coated on the axis body outer surface, and it is characterized in that: the arcuate surface of rubber layer is provided with the different screw thread of rotation direction.
In said structure, preferred scheme is that 1/2nd places with the beaming roller long axis are separating surface, and a side is a single head left-handed thread, and opposite side is the single head right-handed thread.
The sectional shape of screw thread is selected trapezoidal for well in said structure.
Axis body can be selected entity structure, in order to reduce cost, and weight reduction, the preferred axis body of the utility model is by axle, sleeve pipe and be positioned at the sleeve pipe two ends and two end caps being fitted on the axle are formed.
The utility model has the advantages that: rational in infrastructure, can prevent from effectively the deviation phenomenon of line belt in the work or circulating filter-pressing strap to have improved working efficiency, and workmanship.
Below in conjunction with Figure of description, introduce embodiment of the present utility model.
Figure of description 1 is a structural representation of the present utility model;
1-sleeve pipe in the accompanying drawings, 2-rubber layer, 3-screw thread, 4-end cap, 5-axle.
As shown in the figure, axle 5 usefulness 45# steel of the present utility model are made, and use A
3Two end caps 4 that steel is made are fitted on the axle 5 in a usual manner; Sleeve pipe 1 is sleeved on the axle 5 and between two end caps 4; On the outer surface of sleeve pipe 1, coating rubber layer 2; / 2nd places that are processed with on the outer surface of rubber layer 2 with the sleeve pipe major axis are separating surface, and a side is single head dextrorotation, and opposite side is the left-handed screw thread of single head 3.
Claims (4)
