Axle sleeve is separately positioned on mandrel, is provided with the lock tube extended in connecting shaft outer circle on the axle sleeve, the lock tube with connect
Axis is welded and fixed.
In one preferred embodiment of the utility model, the both ends of the roller are respectively arranged with annular groove, the closure
Cover board is respectively embedded into annular groove and welded seal.
In one preferred embodiment of the utility model, sleeve outer circle rear end evagination is provided with to be terminated with before connecting shaft
Tactile spacing ring, the outside diameter of the spacing ring are identical as the outside diameter of connecting shaft.
In one preferred embodiment of the utility model, the lock tube front end is provided with the baffle ring in front of spacing ring.
In one preferred embodiment of the utility model, the lock tube is integrated with baffle ring.
In one preferred embodiment of the utility model, the rear end of the connecting shaft and middle part welding on the outside of closure cover board are solid
It is fixed.
The utility model has the beneficial effects that：A kind of anti-attrition galvanizing sinking roller that the utility model is pointed out, using inside
Vacuum structure effectively reduces dead weight, and diversion trench is arranged in boss surfaces, can be gone out between bushing and axle sleeve by rotary rowed
Particulate matter reduces the friction that axle sleeve rotates in bushing, promotes rotational stabilization and durability.
Description of the drawings
It is required in being described below to embodiment in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
