Abstract
The utility model relates to a shaft sleeve type tensioning wheel which can be widely applied to scraper slag conveyor and other scraper conveying equipments. The shaft sleeve type tensioning wheel comprises a tensioning shaft and a driving shaft used for driving the tensioning shaft; the tensioning wheel is arranged on the tensioning shaft through a shaft sleeve; and the shaft sleeve is fixed on the tensioning shaft by a stainless steel bolt. The shaft sleeve type tensioning wheel has following the benefits: the tensioning wheel is fixed on the tensioning shaft by a stainless steel fixing nut, the hollow shaft sleeve is fixed on the tensioning shaft by the bolt, and certain distance is reserved between the shaft sleeve and a scraper, thus guaranteeing the scraper to pass through and all the returned slag carried by the scraper to enter a groove body of the scraper conveying equipment. A shell of the tensioning wheel is convenient to dismantle, the tensioning wheel has long service life, the shaft sleeve can guarantee the scraper to pass through smoothly, and the slag return rate is high.
Description
Technical field
The present invention relates to a kind of axle sleeve type tension wheel, can be widely used in submerged slag conveyor and other scraper plate load transfer devices.
Background technology
Existing common tension wheel assembly sprocket shaft bearing adopts holding screw or plain round nut to fix.Sprocket shaft bearing adopts the axial restraint pattern of holding screw pattern, and no predetermincd tension, to bear the axial load ability little, sprocket shaft often occurs to the phenomenon that jumps even come off in the actual use; Tension wheel adopts circular nut to carry out axial restraint, and circular nut can guarantee that bearing inner ring has certain predetermincd tension, and circular nut can bear big axial force, guarantees that sprocket wheel does not take place axially to jump and come off easily.But plain round nut and grey pulp water direct contact, plain round nut is perishable, getting rusty causes tension wheel to be difficult to dismounting.Therefore for those skilled in the art of the present technique, seek a kind of for convenience detach, long service life, the tension wheel that afterbody return slag rate is high becomes problem demanding prompt solution.
Summary of the invention
The utility model has overcome above technical matters, and a kind of for convenience detach, long service life is provided, the axle sleeve type tension wheel that afterbody return slag rate is high.
The utility model is achieved through the following technical solutions:
A kind of axle sleeve type tension wheel comprises tensioning shaft and the transmission shaft that drives tensioning shaft, and it is characterized in that: described tension wheel is arranged on the tensioning shaft by axle sleeve, and axle sleeve is fixed on the tensioning shaft by stainless steel bolt.
The more excellent technical scheme of the utility model is: be provided with spacer between described tensioning shaft and the tension wheel; Described tensioning shaft is provided with O shape sealing arrangement, and O shape sealing arrangement is around one week of bearing; Be provided with casing between the tension wheel on the described tensioning shaft.
The beneficial effects of the utility model are: adopt the corrosion-resistant steel captive nut that tension wheel is fixed on the tensioning shaft, the axle sleeve of hollow is fixed by bolts on the tensioning shaft, axle sleeve and scraper plate maintain a certain distance, guarantee scraper plate by and also guarantee that the return slag on the scraper flight can all enter scraper plate load transfer device upper groove body.Tension wheel hub cap convenient disassembly in the utility model, long service life, axle sleeve can guarantee that scraper plate passes through and return slag rate height smoothly.
Description of drawings
The structural representation that Fig. 1 cuts open along axis for the utility model;
Tensioning shaft 1 among the figure, tension wheel 2, spacer 3, bolt 4, casing 5, O shape sealing arrangement 6.
Specific embodiment
Tension wheel hub cap convenient disassembly in the utility model, long service life, axle sleeve can guarantee that scraper plate passes through and return slag rate height smoothly.Because use special corrosion-resistant steel captive nut locking tension wheel, corrosion-resistant steel nut and grey pulp water can not get rusty because of corrosion for a long time, the axle sleeve of hollow is installed on the tensioning shaft with bolt, and axle sleeve and scraper plate maintain a certain distance.Corrosion-resistant steel circular nut corrosion stability height, for convenience detach, axle sleeve can guarantee that scraper plate passes through and return slag rate height smoothly.
