Description
Technical field
The present invention is the front roller shaft axle stream oil-inlet mechanism on a kind of soot blower.
Background technology
The safe operation of boiler is the target of vast boiler user, and the especially Industrial Boiler such as coal-fired and fuel oil is in burning
During, water-cooling wall and superheater etc. can produce serious dust stratification, and the result of dust stratification will certainly reduce the thermal efficiency of boiler,
Exhaust gases passes are blocked, cause vapours temperature to raise, serious causes heating surface booster.In order to remove dust stratification, go out on the market
Show soot blower to be purged its dust stratification, prevent the generation of above mentioned problem.
Existing soot blower is between front roller shaft and bearing, due to reasons such as the sizes and exterior space of guide wheel,
The outside of bearing does not design tank filler sleeve, and implementation is exempted from oiling mode and run, in operation of the environment temperature compared with senior middle school all the year round, its bearing
Grease can be depleted, so cause roller in bearing to be damaged with retainer, bearing is stuck, and the frictional force of soot blower is excessive
Cause it can not free in and out and be stuck in boiler, if carrying out the replacing of whole bearings, the funds of enterprise will certainly be increased drastically
Rise, but also its daily production can be influenceed.
The content of the invention
The invention solves the problems that front roller shaft bearing on existing soot blower cause bearing stuck because grease is depleted and
The unexpected technical problem of generation.
The present invention solve the technical scheme that uses of above-mentioned technical problem for：
The present invention discloses the front roller shaft axle stream oil-inlet mechanism on a kind of soot blower, including two roller bearings and a guide wheel master
Axle, the roller bearing includes outer ring and inner ring, and described two roller bearings or so, which are symmetrically superimposed, to be placed, and the gear of inner ring
Side face is bonded to each other, and guide wheel main shaft passes through the axis hole of bearing inner race, it is characterised in that：In the rib face of bearing inner race provided with a circle
Oil duct, the oil duct inwall is communicated with the axis hole of bearing inner race；If being radially provided with dry sump on the rib of bearing inner race；Oil
Groove is communicated with oil duct；The guide wheel main shaft is a hollow shaft；Match in guide wheel main shaft with the oil duct on bearing inner race rib
Position is provided with a connecting hole, and the hollow part in guide wheel main shaft is connected by the connecting hole with the oil duct on bearing inner race rib, shape
Into axle oil inlet passage.
Hollow axis hole external oil collecting mouth in guide wheel main shaft.
What the present invention can reach has the technical effect that：
The front roller shaft of the present invention is hollow shaft, and oil duct and oil groove are opened in bearing inner race, and hollow shaft is communicated with oil duct, is led to
Cross to oiling in hollow shaft to realize to the oiling in bearing, on the premise of it need not change bearing, it is to avoid grease in bearing
The depleted stuck problem of the bearing brought, both ensure that safety in production, and the funds problem for changing equipment belt is saved again.

Embodiment
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description：
Fig. 1, Fig. 2 are referred to, the present invention provides the front roller shaft axle stream oil-inlet mechanism on a kind of soot blower, including two roller axles
2 and a guide wheel main shaft 1 are held, the roller bearing 2 includes outer ring 4 and inner ring 3, and described two roller bearings 2 or so are symmetrically
Superposition is placed, and the rib face 7 of inner ring 3 is bonded to each other, and guide wheel main shaft 1 passes through the axis hole 8 of bearing inner race 3, in bearing inner race 3
Rib face 7 is communicated provided with a circle oil duct 5, the inwall of oil duct 5 with the axis hole 8 of bearing inner race 3；On the rib of bearing inner race 3
If being radially provided with dry sump 6；Oil groove 6 is communicated with oil duct 5；The guide wheel main shaft 1 is a hollow shaft；With axle in guide wheel main shaft 1
Hold the position that the oil duct 5 on the rib of inner ring 3 matches and be provided with a connecting hole, the connecting hole is by the hollow part in guide wheel main shaft 1
It is connected with the oil duct 5 on the rib of bearing inner race 3, forms axle oil inlet passage.
Hollow axis hole external oil collecting mouth 9 in guide wheel main shaft 1.
The oiling principle of the present invention is as follows：
After soot blower continuously uses a period of time, the oil nozzle 9 in guide wheel main shaft 1 is opened, by oiling equipment toward guide wheel main shaft 1
Hollow shaft in oiling, due to the oil pressure of external oiling equipment, grease enters in the oil duct 5 of bearing inner race 3, treats note in oil duct 5
After full grease, the oil groove 6 that the grease with certain pressure intensity begins through the rib side of bearing inner race 3 is injected into bearing, then right
Oil is filled in whole hollow shaft and bearing, oil nozzle 9 is then covered, when guide wheel, which lives axle 1, to be rotated, due to the roller 10 in bearing
Rolling friction is carried out between bearing inner race 3, so rolling 10 posts just can be by the grease one in oil groove 6, oil duct 5 and hollow shaft
That puts in order is transferred in bearing, has reached the purpose of oiling.
In summary, the front roller shaft axle stream oil-inlet mechanism on soot blower of the invention is simple in construction, and effect substantially, is saved
To the replacement cost of soot blower front jocket wheel, service life is also extended.
