Description
Technical field
This utility model belongs to end cap technical field, particularly relates to a kind of split type end cap for sliding bearing.
Background technology
End cap is the important component part of sliding bearing, mainly for solving the sealing problem between bearing and main shaft.Existing end cap is generally labyrinth seal structure, by setting some dentation sealing rings at end cap endoporus so that it is and between main shaft, produce a series of throttle clearance and annular compartment, realize sealing so that producing throttle effect during lubricating oil flow.But, the vibration produced due to unit operation and the reason such as bearing bush abrasion, main shaft all can be made to produce disturbance so that it is and between the sealing tooth of end cap, produce friction, and cause that throttle clearance increases, impact sealing, add the maintenance cost of sliding bearing unit.
Summary of the invention
This utility model is to provide a kind of split type end cap to solve the problems referred to above.
This utility model the technical scheme is that a kind of split type end cap for solving the problems referred to above, including seal receptacle, sealing ring, pressing plate, bolt, it is characterized in that: seal receptacle is split type structure, it is made up of upper seal support and bottom sealing socket, described upper seal support and bottom sealing socket endoporus are equipped with groove, sealing ring is set in groove, described sealing ring is split type structure, it is made up of upper sealing ring and lower sealing ring, described lower sealing ring and the split surface of bottom sealing socket are equipped with groove, and groove is positioned at lower sealing ring cylindrical and bottom sealing socket endoporus junction, pressing plate is placed in groove, by bolt set in pressing plate and groove, lower sealing ring and bottom sealing socket are combined into an entirety.
The beneficial effects of the utility model are: by such scheme, by non-damageable seal receptacle and the split type setting of sealing ring easy to wear, thus reducing the maintenance cost to end cap, improve the market competitiveness.
Accompanying drawing explanation
Fig. 1 is the structural representation of utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
In figure: 1, sealing ring, 2, seal receptacle, 3, pressing plate, 4, bolt.
Detailed description of the invention
Below in conjunction with accompanying drawing, technical scheme is further described:
As shown in Fig. 1 Fig. 2, this utility model end cap includes seal receptacle 2, sealing ring 1, pressing plate 3, bolt 4, seal receptacle 2 is split type structure, it is made up of upper seal support and bottom sealing socket, described upper seal support and bottom sealing socket endoporus are equipped with groove, sealing ring 1 is set in groove, described sealing ring 1 is split type structure, it is made up of upper sealing ring and lower sealing ring, described lower sealing ring and the split surface of bottom sealing socket are equipped with groove, and groove is positioned at lower sealing ring cylindrical and bottom sealing socket endoporus junction, pressing plate 3 is placed in groove, by bolt 4 set in pressing plate 3 and groove, lower sealing ring and bottom sealing socket are combined into an entirety, owing to end cap is fixed on bearing block, after lower sealing ring is fixing, upper sealing ring also can be automatically positioned.Therefore the end cap of said structure, carries out split setting by sealing ring and seal receptacle, under usual feelings, only need to change consumable accessory sealing ring, thus saving component costs, reduces maintenance cost.
