Abstract
The utility model relates to a dynamic sealing structure of a rotating shaft. The dynamic sealing structure comprises a rotating shaft, wherein an end cover, a bearing cover and a grinding wheel base are sequentially arranged on the rotating shaft; the end cover is fixedly connected with the bearing cover through a bolt; a first water accumulating and discharging groove is formed in the side, connected with the grinding wheel base, of the bearing cover; the grinding wheel base is provided with a second water accumulating and discharging groove; the outer surface of the second water accumulating and discharging groove of the grinding wheel base is set into an inclined surface; the first water accumulating and discharging groove and the second water accumulating and discharging groove are matched to form a maze groove to realize a sealing effect; and the grinding wheel base and the rotating shaft are connected in a key-type connection way. By the dynamic sealing structure of the rotating shaft, in each mounting state of a glass edge grinder, the phenomenon of blockage caused by accumulated grinding cooling liquid is not caused; and meanwhile, the grinding wheel base and the rotating shaft are connected in the key-type connection way, and holes formed in the grinding wheel base by a key are not communicated with one another, so that the cooling liquid is prevented from entering a motor. The dynamic sealing structure is simple in structure and convenient to machine and has certain popularization applicability.
Description
Technical field
The utility model relates to a kind of rotation axis moving seal structure, relates in particular to the rotation axis moving seal structure of a kind of use on glass edge-grinding machine.
Background technology
Glass edge-grinding machine is to produce in the glass machinery deep processing equipment the earliest and one of the cold working equipment of consumption maximum, it mainly is suitable for the processing of furniture glass and building glass and artistic glass, plays the effect to ordinary plate glass base and chamfering grinding and polishing.Bistrique can be between-45 °-225 ° adjusting angle arbitrarily; a bistrique need be equipped with a motor-driven; therefore motor setting angle scope is very big; need the movable sealing of motor shaft under each installment state, can both satisfy requirement of shelter; the motor protection of domestic production is now adopted at end cap and is gone out backbone sealing ring of axis hole place installation; increasing a labyrinth ring about 1mm between emery wheel seat and end cap again seals; the sealing of this structure can be played the better seal effect for shaft extension when horizontal level is above; but it is just very undesirable when installing in level and position below horizontal for shaft extension; cooling fluid can flow to that axle is gone up and be seeped into along axle that motor bearings is indoor to make the bearing corrosion along labyrinth ring when level was installed; cooling fluid can be retained in to arrange in the annular groove of labyrinth and not go out when horizontal level is following; motor is shut down the glass dust that mixes in the cooling fluid when not moving can frozen plug live maze trough, makes motor change motionless and the burning machine.
The utility model content
The utility model purpose is that the rotation axis moving seal structure of a kind of use on glass edge-grinding machine is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of rotation axis moving seal structure, comprise rotating shaft, and be disposed with end cap, bearing cap and emery wheel seat on the described rotating shaft; Be bolted to connection between described end cap and the bearing cap; The side that described bearing cap is connected with the emery wheel seat is provided with the first long-pending rhone; Described emery wheel seat is provided with the second long-pending rhone, and described emery wheel seat is arranged to the inclined-plane at the outer surface of the second long-pending rhone; The described first long-pending rhone cooperates the formation maze trough with the second long-pending rhone, in order to play the effect of sealing.
Preferably, be connected with the key ways of connecting between described emery wheel seat and the rotating shaft.
Preferably, described emery wheel seat is arranged to 45 degree at the tapering on the inclined-plane in the second long-pending rhone outside.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage:
The described rotation axis moving seal structure of the utility model scheme is because the side that described bearing cap is connected with the emery wheel seat is provided with the first long-pending rhone; Described emery wheel seat is provided with the second long-pending rhone, and described emery wheel seat is arranged to inclined plane shape at the outer surface of the second long-pending rhone; The described first long-pending rhone cooperates the formation maze trough with the second long-pending rhone, in order to play the effect of sealing.Grinding coolant can not take place and accumulate the situation that the back is stopped up in rotation axis moving seal structure described in the utility model under each installment state of glass edge-grinding machine; Simultaneously owing to be connected with the key ways of connecting between described emery wheel seat and the rotating shaft, and key is not communicated with in the hole that the emery wheel seat has, and prevented that cooling fluid from entering into the inside of motor; Simple in structure, easy to process, have certain popularization applicability.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of rotation axis moving seal structure described in the utility model;
Wherein: 1, rotating shaft; 2, end cap; 3, bearing cap; 4, emery wheel seat; 5, bolt; 6, the first long-pending rhone; 7, the second long-pending rhone; 8, inclined-plane.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
As accompanying drawing 1 described a kind of rotation axis moving seal structure of the present utility model, comprise rotating shaft 1, be disposed with end cap 2, bearing cap 3 and emery wheel seat 4 on the described rotating shaft 1; Fixedly connected by bolt 5 between described end cap 2 and the bearing cap 3; The side that described bearing cap 3 is connected with emery wheel seat 4 is provided with the first long-pending rhone 6; Described emery wheel seat 4 is provided with the second long-pending rhone 7, and described emery wheel seat 4 is arranged to inclined-plane 8 at the outer surface of the second long-pending rhone 7; The described first long-pending rhone 6 cooperates the formation maze trough with the second long-pending rhone 7, in order to play the effect of sealing; Be connected with the key ways of connecting between described emery wheel seat 4 and the rotating shaft 1; Described emery wheel seat 4 is arranged to 45 degree at the tapering on the inclined-plane 8 in second long-pending rhone 7 outsides.
Grinding coolant can not take place and accumulate the situation that the back is stopped up in rotation axis moving seal structure described in the utility model under each installment state of glass edge-grinding machine; Simultaneously owing to be connected with the key ways of connecting between described emery wheel seat 4 and the rotating shaft 1, and key is not communicated with in the hole that emery wheel seat 4 has, and prevented that cooling fluid from entering into the inside of motor; Simple in structure, easy to process, have certain popularization applicability.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
