Description
Technical field
The utility model relates to belt conveyor roller device, especially a kind of radially online oil filling idler.
Background technique
Currently, the support roller device on belt conveyor is usually successively made of several carrying roller units side by side, referring to Fig. 1,
Each carrying roller unit usually constitutes " V " type structure by the carrying roller of an intermediate flat idler and left and right inclination arrangement.Except this it
Outside, also there is the carrying roller of horizontally disposed installation.
Lubrication and sealing are to influence the key factor of Idler bearing performance.By carrying roller unit each on above-mentioned belt conveyor
Mounting structure it is found that when each carrying roller is lubricated and is sealed, it is necessary to by carrying roller unit each carrying roller carry out according to
Secondary dismounting, and after completing lubrication and sealing to each carrying roller, then successively assembled, this is operationally time-consuming and laborious.Thus,
In practical operation, the oil mass that disposably fills is maintained in carrying roller when the carrying roller used on belt conveyor is all by assembly
The lubrication of bearing, cannot achieve online oiling, not maintain the long time to lubricate；However, existing adopt on carrying roller
With the preferable lip seal of sealing effect or labyrinth seal, but all it is not achieved and prevents from not intaking, not into the ideal purpose of dust.From
And insufficient lubrication, seal bad, this is resulted in, and Idler bearing service life is extremely short, also allows carrying roller to become a kind of pure easy
Damage consumables.
Once occurred the carrying roller oily from shaft end on the market, but from carrying roller unit each carrying roller installation
Structure by three carrying rollers in carrying roller unit each in rack it is found that must disassemble one by one, be just able to achieve axial plus lubricate
Oil, because of its operating process complexity, oiling space is restricted, so that it is very inconvenient to refuel, can not achieve online oiling at all.?
Also have in the market using imported bearing, but also oily because that cannot be carried out in the later period, substantially reduces the use of Idler bearing
Service life.
Summary of the invention
The purpose of this utility model seeks to solve each support in the idler structure that " V " type is arranged on current belt-type conveyer
The bearing lubrication of roller is bad, poor sealing, and because its Idler bearing oiling space is restricted, so that refueling operation is cumbersome,
The problem of can not achieve online oiling provides a kind of radially online oil filling idler thus.
The concrete scheme of the utility model is: a kind of radially online oil filling idler, including roller and roller carrier shaft, in roller
