Abstract
The utility model provides a guide pulley subassembly in dragveyer, includes guide pulley axle and interior guide pulley, interior for the guide pulley key install in the guide pulley epaxially to adopt two round nut fastenings, make guide pulley axle and interior guide pulley rotate simultaneously, be equipped with overflow water ponding groove bottom the interior guide pulley be equipped with the drainage hole on the overflow water ponding groove, the external water conservancy diversion water pipe in drainage hole is followed the inspersed a small amount of buck of dragveyer inslot (the reel shaft seals water) and in the honeycomb duct flows back to grey dragveyer, is avoided the axle of buck contact ball bearing chamber side to rotate the position relatively with the oil blanket to the life of extension sealing washer guarantees that effective lubrication of bearing has guaranteed simultaneously that the outside bad border of dragveyer is pollution -free.
Description
Technical field
The utility model relates to power plant's technical field, is specifically related to a kind of dragveyer inner guide pulley assembly.
Background technology
The existing most dragveyer inner guide pulley used all adopts bearing built-in structure, and namely bearing is loaded between wheel body and guide wheel shaft, for axle fix, wheeling thereof pattern; The structure of oil sealing+O type circle (non-water sealed) or oil sealing+O type circle+water seal (having water seal) is taked in the sealing of bearing, after the long-term operation a period of time that works in buck, due to ring wear, buck inevitably enters bearing bore, cause lubrication failure, bearing damage, inner guide pulley is caused not turn or damage, this situation is not as being found in time, subject-oriented wheel body is polished by chain and dragveyer can be caused to take off chain thus cause dragveyer badly damaged, gives safety in production arrival great hidden danger.
Utility model content
It is simple that technical problem to be solved in the utility model is to provide a kind of structure, the dragveyer inner guide pulley device of economic environmental protection.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of dragveyer inner guide pulley assembly, comprise guide wheel shaft and inner guide pulley, described inner guide pulley key is installed on guide wheel shaft, and adopt two round nut fastening, guide wheel shaft and inner guide pulley are rotated simultaneously, overflow water water storage tank is provided with bottom described inner guide pulley, described overflow water water storage tank is provided with conduction hole, the external water conservancy diversion water pipe of described conduction hole, the a small amount of buck (or shaft seal water) infiltrated in dragveyer groove flows back in grey dragveyer through mozzle, the axle of side, buck contact bearing chamber and oil sealing is avoided to relatively rotate position, thus extend the service life of sealing ring, ensure that the effectively lubricating of bearing ensure that the outside bad border of dragveyer is pollution-free simultaneously.
Between described inner guide pulley and guide wheel shaft, certain span is installed and forms two of dual-gripper and overlap self-aligning roller bearing, described self-aligning roller bearing is placed in bearing seat, being provided with outside framework oil seal and water seal ensures heat-resisting, wear-resistant, Bearing inner pulp water is avoided to pollute, bearing chamber add special Large Copacity spinning lubricating cup and be provided with porus excretorius, can realize easily inner guide pulley grease up.
Further, the seal contacted with buck adopts the seal form of Glais ring, oil sealing and packing according to this at guide wheel end, adopts the techniques such as special light face and hardness process, reduce the wearing and tearing of black box at the guide wheel shaft of sealing place.Black box place leaves certain cavity, is full of waterproof grease, the object making it reach to increase the service life.Bearing external diversion type inner guide pulley is because external bearings is in bearing seat, and grease up path is short, internal resistance is little, replaces old lubricating grease, to supplement new lubricating grease etc. quick, easy.
The beneficial effects of the utility model:
1, comparatively prior art had and significantly promoted inner guide pulley service time, avoided buck and entered bearing chamber, cause bearing damage; Avoid guide pulley body to be polished by chain dragveyer can be caused to take off chain thus cause boiler shutdown, spatter pulp water outward and be disposed in dragveyer by drainage system and avoid environmental pollution.
2, be more conducive to equipment routing inspection during day-to-day operation, can Timeliness coverage problem, process in time, avoid the equipment stoppage in transit accident because inner guide pulley bearing damage bite in running causes.
Accompanying drawing explanation
Fig. 1 is the utility model cut-away view.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in Figure 1, a kind of dragveyer inner guide pulley assembly, comprise guide wheel shaft 1 and inner guide pulley 2, inner guide pulley 2 key 3 is installed on guide wheel shaft 1, and adopt two round nut 4 fastening, guide wheel shaft 1 and inner guide pulley 2 are rotated simultaneously, overflow water water storage tank 5 is provided with bottom inner guide pulley 2, overflow water water storage tank 5 is provided with conduction hole, the external water conservancy diversion water pipe 6 of conduction hole, the a small amount of buck (or shaft seal water) infiltrated in dragveyer groove flows back in grey dragveyer through water conservancy diversion water pipe 6, the axle of side, buck contact bearing chamber and oil sealing is avoided to relatively rotate position, thus extend the service life of sealing ring, ensure that the effectively lubricating of bearing ensure that the outside bad border of dragveyer is pollution-free simultaneously.
Between inner guide pulley 2 and guide wheel shaft 1, certain span is installed and forms two of dual-gripper and overlap self-aligning roller bearing 7, self-aligning roller bearing 7 is placed in bearing seat, being provided with outside framework oil seal and water seal ensures heat-resisting, wear-resistant, Bearing inner pulp water is avoided to pollute, bearing chamber add special Large Copacity spinning lubricating cup 8 and be provided with porus excretorius, can realize easily inner guide pulley grease up.
The seal contacted with buck adopts the seal form of Glais ring, oil sealing and packing according to this at guide wheel end, adopts the techniques such as special light face and hardness process, reduce the wearing and tearing of black box at the guide wheel shaft of sealing place.Black box place leaves certain cavity, is full of waterproof grease, the object making it reach to increase the service life.Bearing external diversion type inner guide pulley is because external bearings is in bearing seat, and grease up path is short, internal resistance is little, replaces old lubricating grease, to supplement new lubricating grease etc. quick, easy.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
