Description
Technical field
This utility model is related to a kind of disintegrating machine line shaft, particularly a kind of shaft end locking structure.
Background technology
In solid waste treating technology application, the blade of disintegrating machine produces powerful axial force in broken material
（Belong to axial internal force N）, this axial force by the spacer ring that contacts with blade and be installed on successively bearing holder (housing, cover) on axle, bearing,
Pressure ring passes up to axle head, and therefore axle head locking needs the part to whole piece axle to provide larger axial lock clamp force, to ensure
Parts on shaft will not produce lateral displacement.
General axle head locking is typically with round nut and coordinates locked spacer locking, or axle head cover locking.Although
Locking will not be problematic, but when dismounting, because disintegrating machine produces axial force in broken material, blade and spacer ring it
Between minim gap plug occur squeeze spot, bearing part produces the axial force of not resiliency in the course of time, so that round nut is subject to than peace
Bigger axial force during dress, now, according to friction formula f=μ N, the frictional force suffered by the bigger round nut of axial force is also bigger,
Thus under powerful axial force N acts on, round nut to be unclamped is very difficult, thus in order to solve the above problems, the design people
Devise a kind of shaft end locking structure, the axial force suffered by round nut can be reduced, thus accordingly also reducing suffered by round nut
Frictional force so that round nut dismounting is easier, and this structure further increases the coupling mechanism force to parts on shaft it is ensured that axle
Functional reliability.
Content of the invention
In order to overcome the deficiencies in the prior art, this utility model provides a kind of shaft end locking structure, and its structure is simple, design
Rationally, can effectively lock and dismantle the part on axle.
This utility model solves its technical problem and be employed technical scheme comprise that：
A kind of shaft end locking structure, including axle and spindle nose, axle is provided with blade and spacer ring, and spindle nose is provided with bearing block, axle
It is provided with bearing in bearing, between bearing and spacer ring, is provided with bearing holder (housing, cover), and the opposite side of bearing is provided with pressure ring, the side of pressure ring is provided with circle
Nut, described blade, spacer ring, bearing holder (housing, cover), bearing and pressure ring locked by round nut it is characterised in that：The end of described spindle nose
Locking cover is installed, and the end face of spindle nose is provided with some screws, locking cover is provided with some corresponding through holes, threaded connector is worn
Cross through hole to be connected with screw and locking cover is fixed on spindle nose, and the end face of the opening of locking cover is pressed on pressure ring.
Described threaded connector is hexagon socket head cap screw.
The end face of the opening of described locking cover is provided with cannelure, and described pressure ring embeds in cannelure.
The beneficial effects of the utility model are：The setting by locking cover for this utility model, when screw lock locking cover
Meanwhile, increased the coupling mechanism force to parts on shaft it is ensured that the functional reliability of axle, and locking cover is applied to pressure ring in dismounting
Plus pressure can reduce axial force suffered by round nut, thus accordingly also reducing frictional force suffered by round nut so that circle
Nut dismounting is easier.
This structure is reliable, practical, the parts on shaft dismounting solving the problems, such as the single locking mechanism of disintegrating machine difficult so that
Disintegrating machine safeguard on the spot convenient, easy to operate.
Brief description
With reference to the accompanying drawings and examples this utility model is further illustrated.
Fig. 1 is sectional view of the present utility model；
Fig. 2 is enlarged partial sectional view.
Specific embodiment
With reference to Fig. 1, Fig. 2, the utility model discloses a kind of shaft end locking structure, includings axle 1 and spindle nose 2, on axle 1 between mistake
It is provided with blade 3 and spacer ring 4, spindle nose 2 is provided with bearing block 5, be provided with bearing 6 in bearing block 5, between bearing 6 and spacer ring 4, be provided with bearing
Set 7, and the opposite side of bearing 6 is provided with pressure ring 8, the side of pressure ring 8 is provided with two round nuts 9, described blade 3, spacer ring 4, bearing
Set 7, bearing 6 and pressure ring 8 are locked by round nut 9, and the end of described spindle nose 2 is provided with columnar locking cover 10, and spindle nose 2
End face be provided with some screws, locking cover 10 is provided with some corresponding through holes, and threaded connector 11 passes through through hole and screw even
Connect and locking cover 10 is fixed on spindle nose 2, specifically, threaded connector 11 is hexagon socket head cap screw, and the opening of locking cover 10
End face be pressed on pressure ring 8, by the setting of locking cover 10, further increase the coupling mechanism force of part on countershaft 1 it is ensured that axle 1
Functional reliability.
As illustrated, as further optimization design, the end face of the opening of locking cover 10 is provided with cannelure, described pressure
Ring 8 embeds in cannelure, consequently facilitating locking cover 10 positions when mounted, and locking cover 10 puts on power on pressure ring 8 more
Plus uniformly.
The principle summary of this structure
Blade 3, spacer ring 4, bearing 6, pressure ring 8 are assemblied on axle 1 and spindle nose 2, install and pretension round nut 9, lock is installed
Hexagon socket head cap screw is simultaneously tightened by tight cover 10 according to GB pretightning force；Stripped nut 9 again；Pretension hexagon socket head cap screw again, instead
Multiple 2 ~ 3 times, now, part firm locking on axle 1.
After equipment is using a period of time, on axle 1, part is subject to axle 1 to extruding force, and between blade 3 and spacer ring 4 very
Spot may be mingled with, thus very big internal force N has been created between part on axle 1, act on round nut 9, because round nut 9 exists
In the case of frictional force f=μ N, frictional force f acting on round nut 9 is very big, without installing locking cover 10 additional, directly
Dismantle round nut 9 using general tool impossible.After having installed locking cover 10 additional, it is solid that locking cover 10 passes through hexagon socket head cap screw
When on spindle nose 2, the end face of the opening of locking cover 10 can bring pressure to bear on pressure ring 8 simultaneously, such that it is able to offset blade 3
It is transmitted through the part axle 1 coming to power so that suffered axle 1 on round nut 9 reduces to power and between spacer ring 4, both ensured that round nut 9 had foot
Enough frictional force will not loosen, and be unlikely to dismantle motionless again, if sensation dismounting is difficult, can also be by screwing hexagon socket head cap screw
Put on pressure on pressure ring 8 to increase locking cover 10, so that suffered axle 1 on round nut 9 is less to power, thus conveniently tearing open
Lower round nut 9.
A kind of axle 1 end locking mechanism above this utility model embodiment being provided, is described in detail, herein
Apply specific case principle of the present utility model and embodiment are set forth, the explanation of above example is only intended to
Help understand method of the present utility model and its core concept；Simultaneously for one of ordinary skill in the art, according to this practicality
New thought, all will change in specific embodiments and applications, and in sum, this specification content should not
It is interpreted as to restriction of the present utility model.
