2020 - TD75 drum sealing improvement
07 -
02 Yang ling, the existence question in belt conveyor in the standard, TD75 belongs to a relatively old standards, and to realize the factory of the belt conveyor about 90% of all belong to this standard.
Of this kind of roller bearing adopt spacer ring and baize of bearing seal, sealed performance is poor, in use after a period of time, distance ring is loose, easy to cause, bearing lock into ashes.
Part of the location of the drum is also easier to replace bearings, but in areas such as the vertical tension roller due to space limitation, change is difficult.
Second, the improvement program refer to the latest TD Ⅱ type A roller bearing processing way, without changing the drum anchor hole size and bearing type cases (
Factories use does not require any changes)
, on roller shaft and bearing assembly size instead of cone axis, so that in order to cooperate with skeleton oil seal.
Car skeleton oil seal and the bearing seat through cover slot, install the corresponding skeleton oil seal.
At the same time reduces the distance ring of bearing seat and the top wire processing, as well as the shaft top silk hole processing, improve the processing efficiency.
Three, the effect after the implementation of the improved roller bearing has been used in ironmaking and sintering online, greatly enhance the sealing effect, at the same time improve the efficiency of the production and processing, saving labor costs.
To realize the factory to replace such roller about tens of thousands of pieces, drum in the future new system process will be long-term use in such way.
