Abstract
The utility model discloses a be used for roller mill muller bearing end plate seal structure, include the end cover body that uses with the muller cooperation, the end cover body is fixed through first bolt and muller, its characterized in that cup joint in the end cover body and be provided with the axle sleeve that uses with the shaft fit, be provided with annular cage on the axle sleeve, it is fixed with the end cover body that the cage passes through the second bolt. The utility model discloses simple structure reasonable in design, axle sleeve and cage through setting up can play better sealed effect, have guaranteed the normal operating of equipment, have practiced thrift the maintenance cost, have improved work efficiency, and the cage is in same horizontal plane with the axle sleeve, avoid the accumulation of dust, the inner wall of end cover body with spool the outer wall between the clearance setting, ensure the flexible rotation of muller.
Description
Technical field
The utility model belongs to bearing machining equipment technical field, is specifically related to a kind of for puddle mixer muller bearing end cap seal structure.
Background technology
Puddle mixer makes each component Homogeneous phase mixing in molding sand, and make adhesive effectively be coated on the equipment of sand grain surface.Puddle mixer utilizes the relative motion of muller and mill disc, is subject to the material be placed between the two rolling the effect of double grinding and comminuting matter, puddle mixer while comminuting matter also by mixing of materials.Produce the ideal equipment that non-burning brick, Dinas brickes, cement brick, refractory brick, pulverizing and mixed powder coal ash, boiler slag, mine tailings and industrial residue make brick-making raw material.
At present, fill felt to seal between the dust-proof most employing end cap of puddle mixer muller bearing (ball) cover and axle, this kind of sealing means is only only applicable to drying, low dirt working environment, and at high dust, moist harsh environments, its dust-proof effect is not good.Add from top to down because puddle mixer is reinforced, in reinforced process, because puddle mixer muller is in rotation, some dust must be had, fine sand falls the position in the square with the axis handing-over of muller dust cap, this position is sealing place of muller bearing (ball) cover, operate for a long time through muller and shake, part dust progresses into muller bearing, in addition, because airtight and watertight padding adopts felt, and felt is not corrosion-resistant, add that working environment is very moist, rotting easily appears in felt, hardening phenomenon, lose original elasticity, dust fine sand is easy to enter in bearing, run out bearing, thus have influence on the service life of bearing.
Utility model content
For problems of the prior art, the purpose of this utility model is that design provides a kind of for puddle mixer muller bearing end cap seal structure.
Described one is used for puddle mixer muller bearing end cap seal structure, comprise with muller with the use of end cap body, described end cap body is fixed by the first bolt and muller, it is characterized in that socket in described end cap body be provided with axle with the use of axle sleeve, described axle sleeve is provided with annular cage, and described cage is fixed by the second bolt and end cap body.
Described one is used for puddle mixer muller bearing end cap seal structure, it is characterized in that described cage and axle sleeve are in same plane.
Described one is used for puddle mixer muller bearing end cap seal structure, it is characterized in that described axle sleeve and axle are interference fits.
Described one is used for puddle mixer muller bearing end cap seal structure, it is characterized in that the described inwall of end cap body and the outer wall of axle leave the gap of 0.4mm-0.5mm.
Described one is used for puddle mixer muller bearing end cap seal structure, it is characterized in that the described inwall of end cap body and the outer wall of axle leave the gap of 0.45mm.
The utility model structure simple designs is reasonable, by axle sleeve and the cage of setting, good sealing effectiveness can be played, ensure that the normal operation of equipment, saved maintenance cost, improve operating efficiency, and cage and axle sleeve are in same level, avoid the accumulation of dust, between the inwall of end cap body and the outer wall of axle, gap is arranged, and guarantees the flexible rotating of muller.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure: 1-muller, 2-end cap body, 3-first bolt, 4-axle, 5-axle sleeve, 6-cage, 7-second bolt.
Detailed description of the invention
The utility model is further illustrated below in conjunction with Figure of description.
As shown in Figure 1, the utility model one is used for puddle mixer muller bearing end cap seal structure, comprise with muller 1 with the use of end cap body 2, end cap body 2 is fixed by the first bolt 3 and muller 1, in end cap body 2 socket be provided with axle 4 with the use of axle sleeve 5, axle sleeve 5 is provided with annular cage 6, this annular cage 6 is fixed by the second bolt 7 and end cap body 2.Wherein, cage 6 and axle sleeve 5 are in same plane, this vibrational power flow, can place the accumulation of dust; Axle sleeve 5 and axle 4 are interference fits; The inwall of end cap body 2 and the outer wall of axle 4 leave the gap of 0.4mm-0.5mm, and optimum is 0.45mm.
The utility model end cap body 2, cage 6 rotate with muller 1, relatively rotate with axle sleeve 5, and the outer wall of the inwall of end cap body 2 and axle 4 leaves the gap of 0.4mm-0.5mm, to ensure muller 1 energy flexible rotating, it is simple that the bearing (ball) cover of this kind of structure has structure, sealing surface outer end is unsettled, more totally; End cap seal length is longer than existing seal length, and sealing effectiveness is better, reduces fault rate, thus saves maintenance cost, heightens operating efficiency.
