Abstract
A novel reciprocating grate supporting wheel comprises a base plate, supporting plates, rolling wheels, a small shaft and bearings. The bottom ends of the two supporting plates are respectively connected to two ends of the base plate. The novel reciprocating grate supporting wheel is characterized in that two ends of the small shaft are supported on the two supporting plates, the rolling wheels are installed on the small shaft through the two bearings, framework oil seals are installed on outer sides of the two bearings, and two ends of each rolling wheel are provided with dustproof covers. One side and the top end of the small shaft are respectively provided with oil filling holes, and oil filling bolts are installed at the hole portions of the oil filling holes. A positioning sleeve sleeved outside the small shaft is installed between the inner sides of the supporting plates and the dustproof covers. The top ends of the supporting plates are provided with grooves, and cross sections of shaft necks of two ends of the small shaft are rectangular and are plugged into the grooves in matched mode. Reinforcing steel plates are arranged in the middles of the outer sides of the supporting plates. The novel reciprocating grate supporting wheel has the advantages of being simple in structure, easy to dismantle, convenient to lubricate and low in manufacture cost, being not easily abraded and prolonging the service life.
Description
Technical field
The utility model relates to a kind of Novel reciprocating furnace grate support roller, this support roller is the movement parts that is connected that is connected and fixed in reciprocal grate between fire-grating frame and travelling oven framed bent, make that the travelling oven framed bent is continuous to move reciprocatingly, thereby make coal round-the-clock motion on fire grate.
Background technology
At present, domestic most of reciprocal grates are all that the afterbody of motion fire grate segment is placed on movable crossbeam, and two of crossbeam is supported on the support roller of rolling.The above-mentioned crossbeam of respectively arranging is connected again, the component movement framework, then it is movable to drive pull bar by reducing gear through eccentric wheel, then makes the motion fire grate segment do the activity of making a return journey.In the middle of this a series of motion, the support roller of rolling plays very important effect.But the support roller on present domestic reciprocal grate has a lot of shortcomings, such as: lubricated bad; Be difficult for installing, dismantling; Wear and tear more serious; Service life is short; High cost.
Summary of the invention
The utility model provides a kind of Novel reciprocating furnace grate support roller, in order to overcome lubricated bad that existing support roller exists, is difficult for installing, and dismounting is worn and torn more serious, and service life is short, the problem that cost is high.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of Novel reciprocating furnace grate support roller, comprise base plate, gripper shoe, roller, little axle and bearing, the bottom of two gripper shoes is connected to the two ends of base plate, it is characterized in that, the two end supports of described little axle is on two gripper shoes, by two bearings, roller is installed on this little axle, in the outside of two bearings, outside framework oil seal is housed, at the two ends of roller, dust cap is housed.
Middle part and top at described little axle have the oil filler point that communicates, and at the oral area of the oil filler point on top, the oiling bolt are housed.
The positioning sleeve that is enclosed within little axle outside is housed between the inboard of described gripper shoe and dust cap.
Top in described gripper shoe is provided with groove, and the cross section of the axle journal at described little axle two ends is rectangle and inserts ordinatedly in this groove.
Outer middle side part in described gripper shoe is provided with the reinforcement steel plate.
Be provided with asbestos seal gasket between described roller two ends and dust cap.
The beneficial effects of the utility model are: simple in structure, be easy to dismounting, and not easy to wear, lubrication ratio is more convenient, has extended service life, and cost is lower.

The specific embodiment
Referring to Fig. 1-Fig. 3, a kind of Novel reciprocating furnace grate support roller, the bottom that comprises base plate 1, gripper shoe 2, roller 13, little axle 14 and 12, two gripper shoes 2 of bearing is welded on respectively the two ends above base plate 1.The axle journal at the two ends of described little axle 14 is supported on two gripper shoes 2, the roller 13 of tubular is installed by two bearings on this little axle 14, in the outside of two bearings, outside framework oil seal 11 is housed, the flange (outward flange) at roller 13 two ends upward is installed with dust cap 15 by bolt 3.Be provided with asbestos seal gasket 10 between described roller 13 two ends and dust cap 15.
In addition, having the oil filler point 16 of the φ 8.8 of mutual conduction at little axle 14 1 ends and middle part, is in order to facilitate oiling, so that for better lubricating bearings, at one end the oral area of oil filler point 16 is equipped with oiling bolt 8.When not needing to inject lubricating oil, the oiling end of little axle 14 can be tightened with bolt 8, prevents that dust from entering.
Between the inboard of described gripper shoe 2 and dust cap 15, the positioning sleeve 9 that is enclosed within little axle 14 outsides is housed.
Be provided with groove 17 on the top of described gripper shoe 2, the cross section of the axle journal at described little axle 14 two ends is rectangle and inserts ordinatedly in this groove 17, realizes that little axle 14 is not connected with gripper shoe 2 rotationally, easy disassembly.
Be welded with leg-of-mutton reinforcement steel plate 7 between the outer middle side part of described gripper shoe 2 and base plate 1.
In use, with bolt 4, pad spring washer 5, nut 6, base plate 1 of the present utility model is fixed on stationary furnace framed bent 18.Strengthen steel plate 7 and be welded on base plate 1, mainly play the effect of strengthening supporting little axle 14, bearing 12, roller 13.Gripper shoe 2 is fixed on base plate 1, is mainly to support whole riding wheel apparatus.
In order to make riding wheel apparatus that better rotary action be arranged, on little axle 14, single row roller bearing 12 is housed.In bearing 12 two ends envelopes, the outside framework oil seal 11 that plays sealing function is arranged, make external dust be difficult for entering in bearing, effectively prevented the wearing and tearing of bearing.Roller 13 in the sealing device outside by tubular surrounds, and is covered with dust cap 15 at roller 13 two-port places, and effect is still to prevent that dust from entering the bearing inboard, and this has just better protected bearing.There is positioning sleeve 9 dust cap 15 outsides, mainly play the spacing and protective effect of pair roller 13.Have slotted hole (as O shape hole) 19 at base plate, play not effect and then assurance roller 13 reliability services of dust stratification.Roller 13 is limited roller, plays the whole position-limiting action to the travelling oven framed bent.
