Abstract
The utility model discloses a seal structure for a dry oil lubrication metal seal ring of a gear coupling. The seal structure consists of an inner gear ring, an outer gear shaft, a gear coupling end cover, a metal seal ring, a dry oil seal end cover and a stop washer, and is characterized in that the inner gear ring is arranged on an outer gear shaft sleeve; the gear coupling end cover is fixedly arranged at the end of the inner gear ring by a bolt; a dry oil lubrication cavity is formed by the gear coupling end cover on the engaging part of the inner gear ring and the outer gear shaft sleeve; the metal seal ring is arranged in the inner hole, contacted with the outer gear shaft sleeve, of the gear coupling end cover; the metal seal ring is fixedly arranged in the inner hole of the gear coupling end cover by the dry oil seal end cover, the stop washer and the bolt; and the metal seal ring is formed by overlapping a plurality of annular metal pieces. The seal structure is applicable to large-angle displacement or is applicable to the work under high temperature conditions.
Description
Technical field
The utility model belongs to the machenical coupling technical field, relates to a kind of sealing configuration of gear coupling dry oil lubrication metal o-ring specifically.
Background technique
At present, the general rubber seal of using O type, J type, Z type or other sectional shape of dry oil lubrication sealing in gear coupling.(angular displacement) angular compensatory amount of general gear coupling is generally 0～1.5 °, uses the conventional seals circle to get final product.And requiring to reach the tooth type universal coupling more than 3 ° in amount for angular compensatory, seal ring just must adopt special shape.For the coupling that uses at worst hot case, like the gear coupling that uses in the steel rolling equipment, its rubber seal is shorter working life, or just can not use basically, and seal ring just must adopt new material and new structure, to satisfy the actual requirement of using.
In addition, gear coupling when installing, has a lot of situation to need hot charging on the axle of machine, when in factory, assembling, can adopt the oil heating, but when assembling at the scene, a lot of situation adopt flame heating.Like this, seal ring lost efficacy because of suffered temperature is too high.
Summary of the invention
The purpose of the utility model is exactly to overcome the deficiency that has dry oil lubrication sealing technique in gear coupling now; Provide a kind of and can be applicable to, or be applicable to the sealing configuration of the gear coupling dry oil lubrication metal o-ring of work under worst hot case than Angular Displacement.
To achieve these goals, the utility model adopts following technological scheme:
A kind of sealing configuration of gear coupling dry oil lubrication metal o-ring is made up of ring gear 1, external tooth axle sleeve 2, gear coupling end cap 3, metal o-ring 4, drier oil end cover 5 and lock washer 6; It is characterized in that: said ring gear is loaded on the external tooth axle; End at ring gear fixedly mounts the gear coupling end caps through bolt 7; And constitute the dry oil lubrication chamber at the engaging piece of ring gear and external tooth axle by the gear coupling end cap; Adorn metal o-ring in the endoporus of the gear coupling end cap that touches being coupling with external tooth, metal o-ring is installed in the endoporus of gear coupling end cap by drier oil end cover and lock washer 6 and through bolt 7; Said metal o-ring is formed by the several ringlike tinsel is overlapping.
The utility model and existing technology compare, and its substantive distinguishing features and positive effect are:
1. because metal o-ring is formed by the several ringlike tinsel is overlapping, when interior external tooth had the big degree of bias relatively, the changing of the relative positions distortion each other freely of metal o-ring sheet adapted to the variation of its various angles, can seal well drier oil.
2. when operating temperature was high, metal o-ring can bear high temperature, and was indeformable, and sealability is stable.
Life-span long, be sealed in the gear coupling life span, need not change.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Embodiment
Specify technological scheme of the present invention below in conjunction with accompanying drawing.
Illustrated in figures 1 and 2, the sealing configuration of a kind of gear coupling dry oil lubrication of the utility model metal o-ring.The sealing structure is made up of ring gear 1, external tooth axle sleeve 2, gear coupling end cap 3, metal o-ring 4, drier oil end cover 5 and lock washer 6; Wherein: ring gear 1, be loaded on the external tooth axle sleeve 2 and be used; End at ring gear 1 fixedly mounts gear coupling end caps 3 through bolt 7; And constitute dry oil lubrication chamber (storing the space of grease) at the engaging piece of ring gear 1 and external tooth axle 2 by the gear coupling end cap; Dress metal o-ring 4 in the endoporus of the gear coupling end cap 3 that contacts with external tooth axle sleeve 2, metal o-ring 4 is installed in the endoporus of gear coupling end cap 3 with lock washer 6 and through bolt 7 by drier oil end cover 5.Said metal o-ring 4 is formed by the several ringlike tinsel is overlapping.
When the utility model needed bigger drift angle when the external tooth axle sleeve with respect to ring gear, each tinsel of forming seal ring can contact with the external tooth axle sleeve along with the changing of the relative positions each other all the time, and the sealing drier oil is not revealed.When the condition of high temperature is used, tinsel is also indeformable, do not lose efficacy.
