Abstract
A kind of winning machine cutting part bearing pin backing stop structure, first lining (3) and the second lining (7) are respectively fixed to coal-winning machine and connect ear mount (8) two ends, bearing pin (6) two ends are set with the first lining (3) and the second lining (7), the upper installation of first lining (3) makes the check ring (5) of bearing pin (6) axially location, end cap (4) is fixed in connection ear mount (8) by screw (1) and lock washer (2), and end cap (4) upper surface is stretched out boss and blocked check ring (5).This utility model effectively prevents coal-winning machine bearing pin from exiting, and improves reliability and the safety of cutting units, and end cap is fixed by screws on connection seat, stretch out boss on end cap and block check ring, make check ring to drop, axially position to the most reliably bearing pin, prevent bearing pin from exiting.
Description
Technical field
This utility model relates to a kind of winning machine cutting part bearing pin backing stop structure.
Background technology
Drum shearer is one of visual plant of current coal mining mechanization and modernization, due to the thickness in coal seam
Inconsistent, drum shearer is wanted full-seam mining to be accomplished by cutting units can to swing up and down.At present, most coal-winning machine is all
It is to carry out hinged by cutting units respectively with tractive unit and oil cylinder, is stretched by oil cylinder, make cutting units around hinged with draw
Point swings up and down.Winning machine cutting part is hinged with tractive unit and oil cylinder is to be connected by bearing pin, when cutting units swings up and down, by
It is sliding friction between housing and bearing pin, time actually used, has axial thrust load, make bearing pin exit.In the design, this axle
Having uncertainty to component, just have the multiple method preventing bearing pin from exiting, majority is all unable to reach expected effect, such as Fig. 2, figure
Shown in 3, traditional bearing pin retaining laminated structure, final stressed member is all screw, and a lot of coal-winning machine maker are all improving, and seek
Prevent the method that bearing pin exits reliably.
Summary of the invention
The purpose of this utility model is: by a kind of winning machine cutting part bearing pin backing stop structure, effectively prevent coal-winning machine
Bearing pin exits, and improves reliability and the safety of cutting units.The technical solution of the utility model is: a kind of winning machine cutting part pin
Axle backing stop structure, the first lining (3) and the second lining (7) are respectively fixed to coal-winning machine and connect ear mount (8) two ends, bearing pin (6) two
End is set with the first lining (3) and the second lining (7), and the upper installation of the first lining (3) makes the spring catch of bearing pin (6) axially location
Circle (5), end cap (4) is fixed in connection ear mount (8) by screw (1) and lock washer (2), and end cap (4) upper surface is stretched out convex
Platform blocks check ring (5).
This utility model, by a kind of winning machine cutting part bearing pin backing stop structure, effectively prevents coal-winning machine bearing pin from exiting,
Improve reliability and the safety of cutting units.Installing check ring on lining, axially position to bearing pin, end cap is solid by screw
It is scheduled on connection seat, end cap stretches out boss and blocks check ring, make check ring to drop, give bearing pin axle the most reliably
To location, prevent bearing pin from exiting.The beneficial effects of the utility model are: this utility model winning machine cutting part bearing pin retaining is tied
Structure, is final stress to have been acted on check ring, and the effect of screw only serves and prevents check ring string from going out
Effect, be not subject to the biggest effect.The most both having added integrally-built reliability, structure is simple again easily to be realized.This
Utility model winning machine cutting part bearing pin backing stop structure equally uses in the structure of other bearing pins.
Accompanying drawing illustrates:
Fig. 1 is this utility model winning machine cutting part bearing pin backing stop structure
Fig. 2 is tradition bearing pin retaining gland structure
Fig. 3 is tradition bearing pin retaining pressure plate structure
Detailed description of the invention
As it is shown in figure 1, a kind of winning machine cutting part bearing pin backing stop structure the first lining 3 and the second lining 7 are respectively fixed to
Coal-winning machine connects ear mount 8 two ends, and bearing pin 6 two ends are set with the first lining 3 and the second lining 7, the first lining 3 is installed and makes pin
The check ring 5 that axle 6 axially positions, end cap 4 is fixed in connection ear mount 8 by screw 1, and boss gear is stretched out in end cap 4 upper surface
Live check ring 5, make check ring 5 to drop, axially position to the most reliably bearing pin 6, prevent bearing pin 6 from exiting.
Claims (1)
