The utility model discloses the preparation is simple and convenient, easy dismounting, and greatly reduced workman intensity of labour improves work efficiency, reduces the spare parts cost.
Description
Technical field
The utility model relates to mining equiment and part field, particularly relates to a kind of New type detachable gyratory crusher locking nut can being convenient to install and remove.
Background technology
Existing Single-Cylinder Hydraulic Cone Crusher, its crushing wall locking function is completed by top locking nut completely, and this locknut appearance and size is comparatively large, is generally cylindrical structural, does not have specific purpose tool, locks and dismantles all extremely difficult.During locking, need, at locknut outer wall welding block, manually to lock with sledgehammer; During dismounting, because screw thread blocks by ore in sand form, and outer wall heavy wear, make dismantlement work more difficult.
Summary of the invention
The utility model overcomes existing gyratory crusher locking nut and is structure as a whole, and dismounting difficulty, holds flimsy deficiency, and a kind of Novel conical crushing machine split of the utility model R & D design locknut, be easy to dismounting, simple for production, workable, operating efficiency is high.
The technical scheme that the utility model solves is: a kind of Novel conical crushing machine locking nut, is made up of locknut core, locknut outer cover, puller bolt, and it is characterized in that locknut in-core circle is saw-tooth thread, outside is designed to positive hexahedron; Install locknut outer cover outside locknut core, locknut outer cover inner chamber is positive hexahedron structure, top design top cover, and top cover axis hole is designed with the seal groove of mounting O-shaped rings, is provided with O type circle in seal groove; There are puller bolt, plain washer, bullet pad in locknut outer cover both sides.
The beneficial effects of the utility model are: the utility model is simple for production, and easy accessibility reduces labor strength greatly, increases work efficiency, and reduce spare parts cost.
Accompanying drawing explanation
Fig. 1 is utility model structural representation.
Fig. 2 is the utility model top view.
In figure: 1, locknut outer cover, 2, locknut core, 3, saw-tooth thread, 4, the outer hexahedron of locknut core, 5, seal groove, 6, locknut cover axis hole, 7, puller bolt, 8, spring washer, 9, plain washer.
Detailed description of the invention
Locknut outer cover (1) inner chamber and outer positive hexahedron (4) respective outer side edges of locknut core in figure.Top cover is arranged at locknut outer cover (1) top, and locknut cover axis hole (6) is designed with the seal groove (5) of mounting O-shaped sealing ring, can effectively prevent sandy soil from entering locknut core screw thread.The uniform puller bolt of locknut outer cover (1) bilateral symmetry (7), spring washer (8), plain washer (9), by fastening to locknut outer cover (1) and locknut core (2), prevent in equipment operation process, the two produces relative motion.Locknut core (2) endoporus be saw-tooth thread (3) with main shaft with the use of, ectosome is that positive hexahedron structure is mated with hexahedron in locknut outer cover, and protection lock body core does not wear and tear by ore charge.When parking needs to overhaul, locknut outer cover is unloaded, aerodynamic wind big gun is connected with locknut core, just can unload easily.
Claims (1)
