Abstract
The utility model discloses a clearance compensation part, which comprises a large compensation sheet, a small compensation sheet, a triangular rod and elastic sheets, wherein the triangular rod is arranged in a first gap between the large compensation sheet and the small compensation sheet; the elastic sheets are arranged in one or more second gaps between the large compensation sheet and the small compensation sheet; the triangular rod has three edges; a first edge is embedded into a groove inside the small compensation sheet, and a top angle which is opposite to the first edge is pressed against the outer side of the large compensation sheet; the groove is formed at any one of the other two edges; the large compensation sheet is crescent; and a circular hole which is used for installing a pin is formed at a large end. By adoption of the structure, the clearance compensation part is simple in structure, convenient to install and high in sealing reliability.
Description
Technical field
The utility model relates to a kind of seal arrangement that is applied to mechanical engineering field, relates in particular to the seal arrangement that a kind of gear pump is used.
Background technique
At present, be applied in the gear pump in order to a lot of to its device that carries out radial seal, its structure and kind are also numerous and diverse various.Some gear pumps are provided with large and small month block teeth usually in the annular space that narrows down gradually that the tooth portion of interior engagement gear ring and small gear is surrounded, come the high low pressure zone isolation in the middle of the moon block teeth again.They adopt the shell fragment encryption and package to put mostly to combine and accomplish sealing; As: adopt shell fragment to do to support, adopt the hemisphere seal bar to seal; Because shell fragment is unstable with the cooperation of hemisphere seal bar; So under the situation of HTHP, can't guarantee the stability that seals, so working procedure is unreliable.
Summary of the invention
The purpose of the utility model is exactly bad in order to overcome the sealability that exists in the above-mentioned existing technology, and the insecure shortcoming of working procedure provides a kind of gap compensating unit, and it is simple in structure, and is easy for installation, and sealing reliability is high.
For realizing the above-mentioned purpose of the utility model, the gap compensating unit of the utility model comprises: large compensation and little compensating plate; Be installed on the triangle rod in first slit between said large compensation sheet and the little compensating plate; Be installed on the shell fragment in one or more second slits between said large compensation sheet and the little compensating plate.
Preferably, said triangle rod has three limits, and its article one limit embeds in the inboard groove of little compensating plate, and the drift angle relative with said article one limit is near the outside of large compensation sheet.
Preferably, arbitrary limit in other two limits in three limits of said triangle rod is provided with a groove.
Preferably, said large compensation sheet is crescent shape, and its big end place is provided with the circular hole that is used for installing pin.
Preferably, said first slit is a V-shaped groove.
Preferably, said second slit is a rectangle groove.
With respect to existing technology, the utility model has the advantages that: simple in structure, easy for installation, sealing reliability is high.
Description of drawings
Fig. 1 is an embodiment's of the utility model the structural representation of gap compensating unit.
Description of reference numerals: 1, large compensation sheet; 2, little compensating plate; 3, triangle rod; 4, shell fragment.
Embodiment
As shown in Figure 1, the gap compensating unit of the utility model comprises: large compensation 1 and little compensating plate 2; Be installed on the triangle rod 3 in first slit between said large compensation sheet 1 and the little compensating plate 2; Be installed on the shell fragment 4 in one or more second slits between said large compensation sheet 1 and the little compensating plate 2.Through cooperatively interacting of triangle rod 3 and shell fragment 4, can make this gap compensating unit have excellent sealing performance; Simultaneously because the form structure characteristics of triangle rod make that its installation is very convenient.
Concrete, the gap compensating unit is made up of with shell fragment 4 large compensation 1, little compensating plate 2, triangle rod 3.Wherein the profile of large compensation sheet 1 is a crescent shape, is provided with a circular hole at its big end place, pin is installed so that large compensation sheet 1 is fixed on the housing of gear pump at this circular hole place.
Between large compensation sheet 1 and little compensating plate 2, be formed with first slit that triangle rod 3 is installed, it is a V-shaped groove.This triangle rod 3 has three limits; Its article one limit is embedded in the groove of little compensating plate 2 inboards; Then abut against the outside of large compensation sheet 1 with the corresponding drift angle in article one limit, so triangle rod 3 all is that the face face contacts with little compensating plate 2 and large compensation sheet 1, and owing to triangle excellent 3 has good fixed characteristic; So such design can be filled up the slit effectively, make sealing reliability be greatly improved; And be provided with a groove on arbitrary the limit in other two limits of triangle rod 3; The design of groove here makes triangle rod 3 have certain Telescopic; Promptly in the difference of using process according to the gear pump working state; Triangle rod 3 can carry out the adjustment of contour projector automatically, so that mate with first slit better.In addition, triangle rod 3 also has simple in structure, convenient installation.
Between large compensation sheet 1 and little compensating plate 2, also be formed with second slit that shell fragment 4 is installed, it is a rectangle groove, and shell fragment 4 is the radial support of large compensation sheet 1 and little compensating plate 2.Adopt shell fragment 4 and the mode that triangle rod 3 matches, can effectively reduce gear pump radially with axial leakage, therefore make the stability raising of sealing, guaranteed that this gap compensating unit has excellent sealing performance.
Although preceding text have been done detailed description to the utility model; But the utility model is not limited thereto; The technician in present technique field can make amendment according to the principle of the utility model; Therefore, all various modifications of carrying out according to the principle of the utility model all are to be understood that to falling into the protection domain of the utility model.
