Abstract
The utility model provides a sealing end cap convenient to disassemble and assemble. The sealing end cap convenient to disassemble and assemble comprises two cap bodies which are mutually spliced and oil seal grooves formed in the two cap bodies. The sealing end cap convenient to disassemble and assemble is characterized in that flanges are arranged on the inner sides of the oil seal grooves, axial grooves or axial flanges are mutually arranged on the inner sides of splicing surfaces of the two cap bodies, radial grooves are formed in the outer sides of the splicing surfaces, and locating keys are arranged inside the radial grooves. Oil seals which are mutually spliced are used in a matched mode, the end cap can be convenient to dissemble, and the oil seals are convenient to replace; meanwhile, the flanges on the inner sides of the oil seal grooves are utilized to prevent the oil seals from axially moving towards the inner sides; and the radial movement and axial movement of two end caps are prevented through cooperation of the axial grooves and the axial flanges, the radial grooves in the outer sides and the locating keys inside the radial grooves, wherein the axial grooves and the axial flanges are mutually arranged on the inner sides of the splicing surfaces of the two cap bodies, so that connecting and sealing performance of the two cap bodies are further improved; and additionally, stop pieces are arranged on the cap bodies on the outer side of the oil seal grooves so that the oil seals can be prevented from axially moving towards the outer sides. The whole of a bucket-wheel mechanism and a retarding mechanism does not need to be disassembled, maintaining efficiency is improved, maintaining time is reduced, and sealing performance is improved.
Description
Technical field
The utility model relates to a kind of end cover, and particularly a kind of assembly unit end cover belongs to Machine Design manufacturing technology field.
Background technique
Material taking machine is important material transfer equipment, is usually used in the mass transport of mine and metallurgy industry.Material taking machine in use; because of bucket wheel mechanism speed reducer lower velocity shaft oil sealing damages oil leak takes place easily; keep in repair in case occur leaking just having to shut down; and maintenance the time need be dismantled the bucket wheel and the speed reducer of material taking machine; then end cover is split out, just can carry out the replacing and the maintenance of oil sealing body afterwards.Because bucket wheel and speed reducer are bulky, the bucket wheel body weight reaches 5 tons, and speed reducer weighs 2 tons, and therefore whole unloading process need expend plenty of time and labour, and what also influence was produced because downtime is long simultaneously normally carries out.If want not dismantle bucket wheel and speed reducer is changed oil sealing, end cap can only be cut into 2 half after, take out the oil sealing that damages, be replaced with new split type oil sealing, will cut into the assembly unit and welding again of two-part end cap again.But the end cap seam crossing after assembly unit and the welding cooperates not closely again, and sealing effect is poor, and the welding rear end cover is heated easily and deforms, and occurs the problem of leakage of oil easily once more, does not reach usage requirement.Therefore be necessary prior art is improved.
Summary of the invention
For solving existing material taking machine when the damage oil sealing is changed, the dismounting amount is big, problems such as repair cycle length, and the utility model provides a kind of only disassemble or assemble end cover just can carry out the replacing of oil sealing body, and the end cover of good airproof performance.
The utility model is finished by following technical proposal: a kind of easy-to-mount end cover, two lids that comprise mutual splicing, be located at the oil sealing groove on two lids, the inboard that it is characterized in that the oil sealing groove is provided with flange, the restriction oil sealing is axial float to the inside, the splicing surface inboard of two lids is established axial notch or axial ledge mutually, radial groove is established in the outside, and be provided with positioning key in the radial groove, prevent the axial leakage of oil of oil sealing with flange by oil sealing groove inboard, and the cooperating of the axial notch of establishing mutually by two lid splicing surface inboards and axial ledge, and the radial groove in the outside and interior positioning key thereof, prevent that two end cap radially, axial float further improves connection and sealability between two lids.
The lid in the described oil sealing groove outside is provided with catch, is used to limit oil sealing axial float laterally.
The utlity model has following advantage and effect: adopt such scheme, and be used the split type oil sealing, can dismantle end cap easily, change oil sealing, flange by oil sealing groove inboard prevents oil sealing axial float to the inside simultaneously, the axial notch of establishing mutually by two lid splicing surface inboards and axial ledge cooperates again, and the radial groove in the outside and interior positioning key thereof, prevent that two end cap radially, axial float, further improve connection and sealability between two lids, add the catch setting on the lid in the oil sealing groove outside, can prevent oil sealing axial float laterally.Need not to dismantle again whole bucket wheel mechanism and reducing gear, improve maintenance efficiency, reduce engineering time, improve sealability.Be a desirable oil sealing end cap in fact.
Description of drawings
Fig. 1 is the end cover structural drawing of the utility model;
Fig. 2 uses scheme of installation for end cover.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
The easy-to-mount end cover that the utility model provides, first lid 3 and second lid 7 that comprise mutual splicing, be located at the oil sealing groove 2 on first lid 3 and second lid 7, so that the oil sealing 14 of splicing is positioned in this oil sealing groove 2 mutually, the inboard of oil sealing groove 2 is provided with flange 10, prevent oil sealing 14 axial float to the inside, axial ledge 4 is established in the splicing surface inboard of first lid 3, corresponding axial notch 8 is established in the splicing surface inboard of second lid 7, with cooperating by axial notch 8 and axial ledge 4, prevent two end cap 3,7 radially, axial float, groove 5 is radially all established in first lid 3 and second lid, 7 outsides, and be provided with positioning key 6 in the radial groove 5, this positioning key 6 is fixed in the radial groove 5 in first lid, 3 outsides by screw 9, to pass through radial groove 5 and interior positioning key 6 thereof, prevent two end cap 3,7 radially, axial float, further improve two lids 3,7 connection and sealability, the lid in oil sealing groove 2 outsides is provided with the catch 1 of mutual splicing, this catch 1 by the hole on it and the screw in the hole on lid, to prevent oil sealing axial float laterally.The end cover 3,7 that the utility model provides is installed on the bearing support 12 of speed reducer lower velocity shaft 13, as Fig. 1, Fig. 2 by screw 11.
Claims (2)
1. easy-to-mount end cover, two lids that comprise mutual splicing, be located at the oil sealing groove on two lids, the inboard that it is characterized in that the oil sealing groove is provided with flange, the splicing surface inboard of two lids is established axial notch or axial ledge mutually, radial groove is all established in the outside, and is provided with positioning key in the radial groove.
2. easy-to-mount end cover according to claim 1 is characterized in that the lid in the described oil sealing groove outside is provided with catch.
