Abstract
The utility model relates to a novel impact crusher, wherein a rotor of the novel impact crusher comprises a main shaft; the main shaft passes through the rotor body; rolling bearings are symmetrically arranged at two sides of the main shaft; parts of the main shaft among the rolling bearings are multi-step symmetrical structures; the multi-step symmetrical structures are clamped at the inner side of the bearings through concave-convex steps of the main shaft; simultaneously, the multi-step symmetrical structures are clamped outside the bearings through a main shaft nut matched with a sealing cover assembly; a locating pin can be assembled through the main shaft nut; and the end of a dead cover is also clamped through a pressure cover matched with a bolt. The novel impact crusher disclosed by the utility model is compact in structure and convenient for processing and overhauling; and the integral reliability of the impact crusher can be effectively increased.
Description
Technical field
The utility model relates to mine mechanism, is specially a kind of impact crusher.
Background technology
In general, impact breaker is as the disintegrating apparatus of medium hardness brittle material, be applied in mine, building materials, construction, metallurgy and chemical industry more, crusher rotor is arranged in crusher shell, the tup that can freely rotate is installed on rotor, drive tup, impact crushing material in back cavity by rotor.Domestic at present generally have two kinds of machines: a kind of is band tapered sleeve machine, a kind of hot charging machine.In process of production, find easily loosening breaking down of tapered sleeve machine bearing tapered sleeve, need often maintenance; And the hot charging machine bearing is inner by decide the seal cover screens, during installation wayward moving, decide the seal cover space, it is overheated easily to occur, and bearing inspection inconvenience.
The impact breaker service condition is abominable, as the rotor of core and critical component be subjected to laterally and radial load all larger, thereby, own recurring structure fracture, broken and rate of breakdown that cause is higher, rotor rack easily on main shaft vibration cause the faults such as seize, how both to have allowed impact breaker durable in use, easy accessibility perplexs vast Design of Mining Machinery and staff always again.
The utility model content
The technical problem that the utility model solves is to provide a kind of impact crusher, and this machine rotor does not use with the bearing of tapered sleeve and installs for avoiding the bearing tapered sleeve loosening, and redesign main shaft and seal cover.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of impact crusher, its rotor comprises main shaft, its main shaft centre position is equipped with tup, and be provided with rolling bearing in tup bilateral symmetry position, the part of described main shaft between rolling bearing is multistage symmetrical structure, and in the rolling bearing inboard by the ladder screens of sinking on main shaft, and do not adopt movable sealing lid screens in traditional fitting machine structure, can effectively reduce installation difficulty; Simultaneously, by the screens of mainshaft nut fitted seal cap assemblies, it is anti-loosening that mainshaft nut can fill alignment pin outside bearing, and the stifle end also can pass through the screens of gland fitted bolt, guarantees that bearing inner race is loosening.
In the utility model, described seal cover assembly comprises to be decided seal cover and is socketed in the movable sealing lid of deciding on seal cover, and described movable sealing lid is installed for the gap, can move by a small margin on the diameter of axle, be bolted on main shaft, convenient maintenance and adjust moving, decide the seal cover space.
Beneficial effect: the utility model compact conformation, reasonable in design, through the impact breaker reliability General Promotion that so designs, overhaul more convenient, machine reliability is high, and the tapered sleeve installing type disintegrating machine compared to traditional structure has reduced rotary packing ring, axle sleeve and bearing tapered sleeve, and cost slightly reduces.
Description of drawings
Fig. 1 is the rotor structure schematic diagram of the utility model preferred embodiment.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Preferred embodiment referring to a kind of impact crusher of Fig. 1, in the present embodiment, its rotor comprises main shaft 6, its main shaft 6 passes rotor rack, and in main shaft 6 two ends symmetric positions, rolling bearing 9 is installed, during making, first with the main shaft 6 two ends bearing 9 installation screens that process, the end face of the hierarchic structure on main shaft 6 is in order to blocking bearing 9 inner faces, and at the outside position car silk of installing of bearing 9 so that mainshaft nut to be installed.
During installation, at first dress movable sealing lid 13 on the axle that installs rotor rack, then set seal cover 10, and hot charging bearing 9, at bearing 9 outside dress bearing blocks 3, will decide seal cover 10 after installing and be fixed by bolts on bearing block 3.After deciding seal cover 10 and installing, first fill shaft nut 2 in stifle 7 inboards again, again by stifle 7 sealings are installed, set seal cover 10 after belt wheel 11 end dress shaft nuts 2, and deciding seal cover 10 outside dress movable sealing lids 13, to decide seal cover 10 use bolts 1 after installing and be fixed on bearing block 3, load onto simultaneously oilhole screw rod 4.It is anti-loosening that mainshaft nut can fill alignment pin, and the screens of gland fitted bolt also can be passed through in stifle end outer end.
Above-mentioned assembling can be installed belt wheel 11 after crossing and claiming to install, and belt wheel 11 ends are fixed by belt wheel expansion set 12 and belt wheel end cap 5 and get final product.Check installation situation, after determining to install, then three movable sealing lids 13 are fixed by bolts on main shaft 6, then whole rotor is contained on frame and gets final product.
Above demonstration and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (2)
1. impact crusher, its rotor comprises main shaft, main shaft passes rotor block, and be provided with rolling bearing in main shaft bilateral symmetry position, it is characterized in that, the part of described main shaft between rolling bearing is multistage symmetrical structure, and in the rolling bearing inboard by the ladder screens of sinking on main shaft; Simultaneously, by the screens of mainshaft nut fitted seal cap assemblies, on described mainshaft nut, alignment pin is housed in the bearing outside, and in the stifle outer end of rotor block end face by the screens of gland fitted bolt.
2. a kind of impact crusher according to claim 1, is characterized in that, described seal cover assembly comprises to be decided seal cover and be socketed in the movable sealing lid of deciding on seal cover, and the movable sealing lid is installed for the gap, is bolted on main shaft.
