Abstract
The utility model relates to a slide bearing's end cover is formed by two seal assembly that the structure is the same combinations, seal assembly includes seal receptacle, sealing ring, spring leaf, rivet and spacing bolt, its characterized in that: the seal receptacle hole is equipped with the recess, is equipped with the sealing ring in the recess to sealing ring excircle and recess hole have the clearance, and the terminal surface is equipped with spacing bolt, and spacing bolt passes the sealing ring through -hole that the terminal surface is established, the sealing ring hole is equipped with sealed tooth, and the excircle is equipped with the spring leaf, the spring leaf is rectangle elasticity strip, through fix with rivet at the sealing ring excircle. Through above -mentioned scheme, the adoption of free -standing labyrinth ring, spacing bolt and spring strip for during the main shaft disturbance, through the elastic force that the spring strip produced, make the sealing ring float along with the main shaft, thereby reduced the frictional force on sealed tooth and main shaft surface effectively, improved end cover's life.
Description
Technical field
This utility model belongs to end cap technical field, particularly relates to a kind of 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, generation one is
Row throttle clearance and annular compartment, thus produce throttle effect when lubricating oil flow and realize sealing.But, due to unit operation
The reasons such as the vibration produced and bearing bush abrasion, all can make main shaft produce disturbance, cause producing between itself and the sealing tooth of end cap
Friction, makes throttle clearance increase, and impact seals.Therefore, how to reduce main shaft and the frictional force sealed between tooth, improve end cap and make
With the life-span, it it is our problem of needing solution badly.
Summary of the invention
This utility model is to provide a kind of end cap to solve the problems referred to above.
This utility model the technical scheme is that a kind of end cap for solving the problems referred to above, by identical close of two structures
Sealing assembly combines, and described black box includes seal receptacle, sealing ring, spring leaf, rivet and caging bolt, and its feature exists
In: seal receptacle endoporus is provided with groove, is provided with sealing ring in groove, and sealing ring cylindrical has gap, end face with groove endoporus
Being provided with caging bolt, and caging bolt is through through hole set by sealing ring end face, described sealing ring endoporus is provided with sealing tooth, and cylindrical sets
Having spring leaf, described spring leaf is rectangle elastic strip, is fixed on sealing ring cylindrical by rivet.
The beneficial effects of the utility model are: by such scheme, adopting of stand alone type labyrinth ring, caging bolt and spring
With so that during main shaft disturbance, the elastic force produced by spring, make sealing ring with spindle floating, thus efficiently reduce
Seal the frictional force of tooth and main shaft surface, improve the service life of end cap.
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, caging bolt, 4, spring leaf, 5, rivet.
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 is combined by the black box that two structures are identical, described sealing
Assembly includes that seal receptacle 2, sealing ring 1, spring leaf 4, rivet 5 and caging bolt 3, seal receptacle 2 endoporus are provided with groove, in groove
Being provided with sealing ring 1, and sealing ring 1 cylindrical has larger gap with groove endoporus, its end face is provided with caging bolt 3, and spacing
Bolt 3 is through through hole set by sealing ring 1 end face, and described sealing ring 1 endoporus is provided with sealing tooth, and cylindrical is provided with spring leaf 4, described bullet
Reed 4 is rectangle elastic strip, is fixed on sealing ring cylindrical by rivet.By such scheme, stand alone type labyrinth ring, spacing spiral shell
Bolt and the employing of spring so that during main shaft disturbance, due to the produced elastic force of spring, make sealing ring with spindle floating,
Thus efficiently reduce the frictional force sealing tooth with main shaft surface, improve the service life of end cap.
