Description
Technical field
The utility model relates to motor sealing device, belongs to technical field of motors.
Background technology
Along with social development, the scope of application of motor expands.In a lot of special industries to motor different performance requirements also proposed, as coal industry is had relatively high expectations to the water proofing property of motor, after water leak accident occurs, water can enter rotor by motor output shaft, cause motor to damage, even cause drainage system paralysis, the escape time of down-hole miner is shortened.The utility model is set up outside framework oil seal in end cap inside, outside framework oil seal is provided with inside loop and outside loop shape circle, and be provided with dust ring at bearing two ends, by a plurality of sealings, arrange, make water can not infiltrate at output shaft position motor, motor can continue to run well and drive water pump to carry out draining after water leak accident occurs, and water proofing property is better, safe.
Summary of the invention
The purpose of this utility model is to provide a kind of motor sealing device, in end cap inside, set up outside framework oil seal, outside framework oil seal is provided with inside loop and outside loop shape circle, and is provided with dust ring at bearing two ends, by a plurality of Sealing Device are set, make water can not infiltrate at output shaft position motor.
For achieving the above object, the utility model provides a kind of motor sealing device, comprise motor body, the inside of described motor body is provided with rotating shaft, and a side of motor body is provided with the end cap of sealing use, described rotating shaft is connected with end cap by bearing, and described bearing rear and front end is respectively equipped with rubber dust cap; Described end cap front end is provided with a counterbore shape cavity, in described cavity, be provided with an outside framework oil seal, described outside framework oil seal comprises circular inner ring and outer ring, internal diameter and the rotating shaft of described inner ring are suitable, and cover has a spring on the cylindrical of inner ring, cylindrical and the cavity of described outer ring closely cooperate, and and bearing between leave gap.Outside framework oil seal is compressed into cavity, and outer ring and cavity closely cooperate, and plays the effect of waterproof water spray; When inner ring rotates wearing and tearing because of rotating shaft, spring shrinks inner ring, and rotating shaft and inner ring are closely cooperated, and plays anti-spraying effect; Outer ring and bearing have certain interval, guarantee that outer ring rear end face and the bearing dustproof cover of outside framework oil seal do not interfered; The dust cap of contact for bearing, plays secondary waterproof action.
Further improvement of the utility model is: described outside framework oil seal adopts quality of rubber materials, and good airproof performance is convenient to produce.
The beneficial effects of the utility model are: outer ring and cavity closely cooperate, and play the effect of waterproof water spray; When inner ring rotates wearing and tearing because of rotating shaft, spring shrinks inner ring, and rotating shaft and inner ring are closely cooperated, and plays anti-spraying effect; Outer ring and bearing have certain interval, guarantee that outer ring rear end face and the bearing dustproof cover of outside framework oil seal do not interfered; The dust cap of contact for bearing, plays secondary waterproof action.Seal is with low cost, replaceable use, and maintenance is little, easy to use.
Accompanying drawing explanation
Fig. 1 represents that master of the present utility model is depending on partly cuing open figure;
Fig. 2 represents the structural representation of the utility model outside framework oil seal;
Drawing reference numeral: 1-motor body, 2-end cap, 3-rotating shaft, 4-bearing, 5-outside framework oil seal, 6-spring, 7-inner ring, 8-outer ring, 9-rubber dust cap.
Embodiment
In order to deepen, to understanding of the present utility model, below in conjunction with drawings and Examples, the utility model to be described in further detail.
By reference to the accompanying drawings 1 with accompanying drawing 2, the utility model proposes a kind of motor sealing device, comprise motor body 1, the inside of described motor body 1 is provided with rotating shaft 3, and a side of motor body 1 is provided with the end cap 2 of sealing use, described rotating shaft 3 is connected with end cap 2 by bearing 4, and described bearing 4 rear and front ends are respectively equipped with rubber dust cap 9; Described end cap 2 front ends are provided with a counterbore shape cavity, in described cavity, be provided with an outside framework oil seal 5, described outside framework oil seal 5 comprises circular inner ring 7 and outer ring 8, the internal diameter of described inner ring 7 and rotating shaft 3 are suitable, and cover has a spring 6 on the cylindrical of inner ring 7, cylindrical and the cavity of described outer ring 8 closely cooperate, and and 4, bearing leave certain gap.Described outside framework oil seal 5 adopts quality of rubber materials.Outside framework oil seal 5 is compressed into cavity, and outer ring 8 closely cooperates with cavity, plays the effect of waterproof water spray; When inner ring 7 rotates wearing and tearing because of rotating shaft 3, spring 6 shrinks inner ring 7, and rotating shaft 3 is still closely cooperated with inner ring 7, plays anti-spraying effect; There is certain interval outer ring 8 with bearing 4, guarantees that outer ring 8 rear end faces and the bearing rubber dust cap 9 of outside framework oil seal 5 do not interfered; The rubber dust cap 9 of bearing 4 use contacts, plays secondary waterproof action.
Whole device arranges by sealing from level to level, and anti-sealing enters motor internal by motor shaft, plays the effect that protection motor does not affect again the normal work of motor.Use sealing device all to adopt quality of rubber materials, with low cost, replaceable use, maintenance is little, easy to use.
