Description
Technical field
The utility model relates to field of cracking machine, is specifically related to a kind of novel gyratory crusher.
Background technology
Present existing gyratory crusher comprises frame, is fixedly installed on the fixedly circular cone (being called for short fixed awl) in the frame, main shaft and movable circular cone (abbreviation mantle); The space that forms between mantle and the fixed awl is crusher chamber.Mantle is set on the main shaft, and mantle also is arranged with tapered sleeve outward; And by the axle journal on main shaft top locking screw is set, and cooperates with locking screw by mainshaft nut tapered sleeve is pressed abd fixed on the mantle.The upper end of main shaft is rotating to be placed in the dead eye of crossbeam top; The main shaft lower end is rotating to be placed in the excentric sleeve, and with the rotation of excentric sleeve, mantle is done the swing campaign around the disintegrating machine center line together with main shaft; And then the material that will enter in the crusher chamber is squeezed and fragmentation.Disintegrating machine is usually by motor-driven, and to main shaft main shaft rotated power transmission by power drive mechanism.Power drive mechanism generally includes power transmission shaft, is arranged on the driving gear of power transmission shaft end, is fixed on the ring gear on the excentric sleeve.The power of motor is passed to ring gear and excentric sleeve through power transmission shaft and driving gear, thereby makes main axis rotation, drives mantle and does turning motion.
In addition, oil circuit that enters excentric sleeve, main shaft, power drive mechanism and disintegrating machine inside for dust and the particle that prevents from crusher chamber etc. must arrange dustproof construction at gyratory crusher.The dustproof construction of gyratory crusher adopts the lip ring that arranges in frame usually at present, and the top of this lip ring is extended obliquely and compressed on the main shaft that is coated on the excentric sleeve top.
For example, Chinese patent publication number CN201131390, open day on October 15th, 2008, the name that utility model is created is called sealed crusher, its power drive mechanism comprises power transmission shaft, is arranged on the driving gear of power transmission shaft end, is fixed on the ring gear on the excentric sleeve; The axle journal on its main shaft top is provided with the locking screw for the locking tapered sleeve; Be provided with dustproof construction between its frame and main shaft, its dustproof construction comprises the seal cover that is arranged on the mantle below, and seal cover also passes through seal and the main shaft seal of seal cover inward flange around main shaft.
Present gyratory crusher has following deficiency:
One is easy to generate loosening between the driving gear of long-term use medium power transmission mechanism and ring gear; In order to guarantee the operate as normal of driving gear and ring gear, prolong the service life of gear, need regularly to detect the backlash between driving gear and the ring gear.
At each backlash that detects between driving gear and the ring gear on the present gyratory crusher, all need after the gyratory crusher dismounting, adopt the method for pressing lead wires to detect the size of backlash then.If backlash is bigger than normal, then needing to adjust the method for pad by increase and decrease will be for the position of the annular seat ring of installing ring generating gear, and then the backlash between driving gear and the ring gear is met the requirements.The detection of the driving gear of the power drive mechanism of gyratory crusher and the backlash between the ring gear at present, adjustment are not only complicated, loaded down with trivial details, and workload is big, operating efficiency is low, and backlash adjustment precision is low.
Its two, the dustproof poor effect of the dustproof construction on the present gyratory crusher, the especially lubricating oil in the space on eccentric bushing top in the oil return process since this space of oil return of lubricating oil in will form negative pressure gradually; And the part dust of crusher chamber and particle will together enter oil circuit inside by the slit of dustproof construction in company with extraneous air stream under suction function, make lubricating oil contain a large amount of dust, this not only can make the part accelerated wear test of respectively turning round, and shortens the service life of the part that respectively turns round; And make oil return not smooth, and cause lubricating oil excessive from dustproof construction, make oil leak serious.
Its three because the outer sheathed tapered sleeve of mantle need be locked by mainshaft nut, the locking screw of tapered sleeve generally all is located on the axle journal on main shaft top at present; And because the terminal of screw thread has escape one, the setting of escape has not only reduced the intensity of main shaft, concentrates but also be easy to generate stress; Thereby present main shaft most of off-axis in the rotary work process all occurs in escape.
The utility model content
First purpose of the present utility model be for the detection of the driving gear that overcomes existing gyratory crusher and the backlash between the ring gear and adjustment process not only complicated, loaded down with trivial details, workload is big, operating efficiency is low, and backlash adjustment precision is low, a kind of backlash that can conveniently detect and adjust between driving gear and the ring gear is provided, and adjusts the high gyratory crusher of precision.
The utility model another purpose on the first purpose basis is the dustproof poor effect for the dustproof construction that overcomes existing gyratory crusher, the problem that the part dust of crusher chamber and particle enter oil circuit inside easily, a kind of dustproof effect that can effectively improve the gyratory crusher dustproof construction is provided, avoid part dust and the particle of crusher chamber to enter oil circuit inside, the gyratory crusher of lubricating oil eometamorphism and excessive leakage phenomenon in the eliminating production run.
Three purpose of the utility model on the first purpose basis is in order to overcome the problem that off-axis takes place at the escape place of locking screw existing main shaft easily in the rotary work process, provide a kind of and can effectively solve the problem that off-axis takes place at the escape place of locking screw main shaft easily in the rotary work process, and improve the gyratory crusher of main axe intensity.
