Description
Technical field
The utility model belongs to bar, sealing apparatus field, relates to a kind of aligning-type reducing sealer.
Background technology
The movable sealing of current bar generally adopts sealing ring to seal or packing seal, when adopting sealing ring sealing, change sealing ring the head coupling part of bar all to be dismantled and then sealing ring is inserted in, wastes time and energy especially, be especially embodied in the reduction box of heavy-duty machines, hydraulic stem sealing; When adopting packing seal, then need squeeze in seal chamber by new packing by old packing pullout, adding procedure wastes time and energy, and is especially embodied in oil-extractor polish-rod sealing and replaces with; Because the problems such as load is large, assembly precision, kinematic accuracy also have a lot of bar and capsule walls decentraction, cause eccentric wear, have a strong impact on sealing effectiveness and seal durability; And mechanical seal cannot be applied to all axle movable sealings (as speed reduction box shaft sealing), more reciprocating movable sealing cannot be applied to.Therefore, need corresponding sealing device to overcome these defects, bring convenience to actual production.
Summary of the invention
The purpose of this utility model is to provide a kind of aligning-type reducing sealer, overcome the replacing of current encapsulant, filling trouble wastes time and energy and bar and capsule walls and bar, axle decentraction problem.
The utility model is achieved through the following technical solutions: a kind of aligning-type reducing sealer, comprise and emit lid, outer shell, reducing inner bag, upper flange lid, lower flange with connector and seal, wherein, on emit lid central authorities have hole, on emit lid be connected with the upper external thread of outer shell by internal thread, the internal thread of outer shell is connected with the external screw thread of reducing inner bag, it is inner that seal is contained in reducing inner bag, the top of reducing inner bag is arcwall face, there is the shoulder outwards extended bottom, the lower flange of upper flange lid and band connector is connected to the both sides up and down of shoulder.
Further, also comprise gland, described gland central authorities have hole, and gland top contact emits lid, and bottom can extend into contact seals in reducing inner bag.
Further, described reducing inner bag bottom inside is provided with baffle plate.
Further, the external diameter of described reducing inner bag is less than the diameter of bore of upper flange lid, and the shoulder diameter of reducing inner bag is less than the diameter of the lower flange of band connector.
Further, described seal is through the rubber column circle of helical cut.
Adopt the good effect of technique scheme: the utility model structure simply but considerably increases the efficiency that changes the outfit, first seal is put into diameter larger outer shell when filler is installed, advanced downwards by screw thread rotation, seal is squeezed in the less reducing inner bag of diameter, filling, change seal easily very convenient, more than human time's twice can be saved; Can also concentricity adjustment be carried out, solve eccentric wear problem; Make seal enter minor diameter cavity owing to have employed, extruding produces sealing, then pushing seal makes seal expansion produce sealing upon wear, adds seal process, improves the service efficiency of seal, seal is enhanced about more than once service time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of seal in Fig. 1.
In figure, on 1, emit lid, 2 outer shells, 3 reducing inner bags, 4 upper flange lids, the lower flange of 5 connectors, 6 seals, 7 glands, 8 baffle plates.
Detailed description of the invention
below in conjunction with accompanying drawing, technical scheme of the present invention is described further, but should not be construed as limitation of the present invention:
Fig. 1 is structural representation of the present invention, as shown in the figure, a kind of aligning-type reducing sealer, comprises and emits lid 1, outer shell 2, reducing inner bag 3, upper flange lid 4, the lower flange 5 being with connector and seal 6, wherein, on emit lid 1 central authorities to have hole, pass from central authorities for bar, above emit lid 1 to be connected by the upper external thread of internal thread with outer shell 2, the internal thread of outer shell 2 is connected with the external screw thread of reducing inner bag 3, it is inner that seal 6 is contained in reducing inner bag 3, for holding bar tightly.The top of reducing inner bag 3 is arcwall face, there is the shoulder outwards extended bottom, the lower flange 5 of upper flange lid 4 and band connector is connected to the both sides up and down of shoulder, the effect of the top arcwall face of reducing inner bag is convenient to seal rotate into reducing inner bag from top, and the lower flange of band connector is used for the connection of this device with other devices.
Advance downwards for the ease of being rotated by seal, also comprise gland 7, described gland 7 central authorities have hole, and gland 7 top contact emits lid 1, and bottom can extend into contact seals 6 in reducing inner bag 3.Therefore, when above emitting lid to advance, first advance gland downwards, and then advance seal, gland can be advanced in reducing inner bag always extrude seal, when being expressed to a certain degree, can also lid be emitted again to extrude on rotating.
In order to block seal bottom, described reducing inner bag 3 bottom inside is provided with baffle plate 8.
This device possesses the function of aligning, and the external diameter of described reducing inner bag 3 is slightly less than the diameter of bore of upper flange lid 4, and the shoulder diameter of reducing inner bag 3 is less than the diameter of the lower flange 5 of band connector.This kind of design can ensure that reducing inner bag carries out certain planar movement between upper flange lid and the lower flange of band connector, thus realizes the effect of aligning.
Fig. 2 is the structural representation of seal in Fig. 1, as shown in the figure, described seal 6 is through the rubber column circle of helical cut, its cylinder top and bottom are smooth, the effect that can play conventional seals circle can solve again the problem that seal must be inserted in through bar, makes seal bearing up-down force even simultaneously.
During use, because casing and reducing inner bag constitute two cavitys of different-diameter, first seal is loaded in casing, because casing diameter is larger, filling get up very convenient time saving and energy saving, then put into gland, by emit lid to screw on, such outer shell and above emit cover be connected after turn to lower propelling by the external thread rotary of reducing inner bag, realize the effect of screw jack, seal is pressed in the less reducing internal bladder cavity of diameter, realizes sealing.When seal uses appearance wearing and tearing for a long time, by gland pushing seal, seal expansion is produced and seal, add seal process, improve the service efficiency of seal, extend the application life of seal.
Structure of the present invention is simple, first seal is put into diameter larger outer shell when filler is installed, advanced downwards by screw thread rotation, seal is squeezed in the less reducing inner bag of diameter, filling, change seal easily very convenient, more than human time's twice can be saved; Can also concentricity adjustment be carried out, solve eccentric wear problem.
