Abstract
The utility model discloses a kind of roll wheel assembly, for the traveling gear in high load capacity, orbit determination road, comprises roller and wheel shaft, and one end of wheel shaft coordinates with roller by being equipped with bearing, and the other end of wheel shaft is fixed on traveling gear by Flange joint.This assembly, by running in bearings between each slide unit, reduces the friction between slide unit, adds the service life of roll wheel assembly and each parts, and improve operating efficiency.
Description
Technical field
The utility model relates to a kind of roll wheel assembly, is mainly used in the traveling gear in high load capacity, orbit determination road.
Background technology
The traveling gear in high load capacity, orbit determination road, as on the equipment such as electric flat carriage, has vast usage space.Electric flat carriage, also known as electric flatbed tricycle, electric flatcar, chassis, straddle carrier, electric motor-trolley, ground creeping vehicle etc., be rail electric transportation vehicle in a kind of factory, it is a kind of rail type transportation vehicle, need to lay track on the ground, track is generally I-shaped profile contact track; Secondly it is electro-motive vehicle, automatically run under motor reducer drives, it is a kind of flat truck again, and table top is smooth to be covered without railway carriage or compartment, in particular cases also can be on-plane surface but cover without railway carriage or compartment, the directionless dish of car body only has forward-reverse direction (track turn is leaned in also city even if turn).This kind of vehicle have that structure is simple, easy to use, load-carrying capacity large, be not afraid of dirty be not afraid of pound, safeguard easily, the feature such as long service life, because of plurality of advantages such as it is convenient, sturdy, economic, practical, easy to clean, become working shop of enterprise first-selected transportation means that is inner and short range fixed point frequent delivery weight between factory building and factory building, market outlook are vast, and there are wearing and tearing greatly in the major part roll wheel assembly being applied to this traveling gear at present, load-carrying capacity is inadequate, fragile, affect the defects such as conveying efficiency.
Summary of the invention
In order to solve prior art deficiency, the utility model provides a kind of roll wheel assembly, and this assembly, by running in bearings between each slide unit, reduces the friction between slide unit, adds the service life of roll wheel assembly and each parts, and improve operating efficiency.
The technical solution adopted in the utility model is:
A kind of roll wheel assembly, for the traveling gear in high load capacity, orbit determination road, comprise roller and wheel shaft, one end of described wheel shaft coordinates with roller by being equipped with bearing, and the other end of wheel shaft is fixed on traveling gear by Flange joint.
Described roller has cavity, the first limit dais is provided with in cavity, wheel shaft one end that bearing is housed is placed in cavity, one lateral edges of bearing outside diameter and the first limit dais effect, one lateral edges of bearing bore diameter and the back-up ring effect be arranged on wheel shaft, the second limit dais effect that the opposite side edge of bearing bore diameter and wheel shaft are arranged.
Described roll wheel assembly, also comprises end cap, and be arranged on cavity outer and be set on wheel shaft, be connected with the roof of cavity by bolt, the sidewall that end cap is positioned at cavity is provided with flange, the opposite side edge action of flange and bearing outside diameter.
Described roll wheel assembly, the position being positioned at axis at the outer wall of wheel shaft is provided with the through hole be communicated with cavity, and described through hole is provided with priming cup.
A kind of roll wheel assembly of the utility model has following beneficial effect:
The utility model roll wheel assembly structure is simple, installs and easy to make, improves the conveying efficiency of traveling gear supporting with it.By running in bearings, play transitional function, reduce the friction between slide unit (roller and wheel shaft), extend the service life of roll wheel assembly and each parts, improve operating efficiency.The excellent properties that the utility model roll wheel assembly can give full play to traveling gear is installed, increases work efficiency, save cost.
By installing end cap, together with end cap coordinates with roller, bearing felt being got up, preventing bearing from entering the impurity such as dust.
Priming cup is installed, between each parts of pair roller assembly, plays lubricating effect.
