Abstract
The utility model discloses a split large gear ring for a rotary cement kiln. The split large gear ring comprises a large gear ring body which is of a circular ring shape formed by combining a plurality of gear sections. The end faces of the gear sections are provided with adjusting holes. The edges of the inner sides of the gear sections are provided with center holes. The edges of the outer sides of the gear sections are uniformly provided with first saw-teeth. The two side faces of the gear sections are provided with a plurality of connecting holes. The large gear ring body is driven by a small gear ring body arranged on the outer side of the large gear ring body. The outer side of the small gear ring body is provided with second saw-teeth matched with the first saw-teeth. As the design of a plurality of the gear sections is adopted, and the gear sections are completely interchangeable, when a part of the large gear ring body is damaged, only the damaged gear section needs to be replaced, the whole gear ring body does not need to be replaced, and therefore the split large gear ring is reasonable in structure, and convenient to install, transport, maintain and replace.
Description
Technical field
The utility model relates to fire resisting material field, is specifically related to a kind of split bull gear of cement rotary kiln.
Background technology
Rotary kiln is being born clinker burning task in technology of producing cement, has very unique function, and bull gear plays vital effect rotary kiln in service.Traditional bull gear material is often high-intensity spheroidal graphite cast-iron or cast steel, only carry out necessary heat treatment, casting quality is controlled and is difficult to meet the demands, cause workpiece to tend to repair with repair welding, the final complete performance that affects gear ring, the while also exists because oversize causing occurs reaching the problems such as matching requirements in transportation difficulty or on-the-spot installation rotary kiln device in transportation installation process.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of split bull gear of cement rotary kiln.
Technical scheme: for solving the problems of the technologies described above, the split bull gear of a kind of cement rotary kiln of the present utility model, comprise bull gear, described bull gear is combined to form circular by some tooth sections, on described tooth section end face, be provided with adjusting hole, tooth section inside edge is provided with centre bore, and tooth section outer ledge is evenly provided with the first sawtooth, and the two sides of tooth section are provided with some connecting holes; Described bull gear is driven by the little gear ring of being located at bull gear outside, and little gear ring outside is provided with second sawtooth suitable with the first sawtooth.
Preferably, described tooth section integral body is circular arc, annulus of each tooth section formation capable of being combined; Thereby by bolt being inserted in the adjacent connecting hole of adjacent two tooth sections, realize the connection to adjacent two tooth sections, be connected with latch plate on centre bore, the other end of latch plate is installed on the cylindrical shell of cement rotary kiln; In order precisely to adjust adjusting hole described in the axial location of bull gear and radial position, have two at least, as preferably, the end face of tooth section has two adjusting holes.
Preferably, the cross section of described tooth section side is " work " font, and in order to strengthen the bonding strength between each tooth section, in described " work " word, the two ends, left and right of montant are all vertically provided with connecting hole.
Beneficial effect: the split bull gear of a kind of cement rotary kiln of the present utility model, compared with prior art, have the following advantages: adopt the tooth section design of multistage, each tooth section is exchanged completely, when the part of bull gear is damaged, only need to changes bad tooth section, and not need to change whole gear ring, this is fine has solved traditional heavy castings quality instability problem, cost-saving; Can gradation handling bull gear during on-the-spot installation, quick and easy for installation; Can segmentation transport tooth section, transportation is simplified, effectively protect split bull gear; Bull gear is arranged on cylindrical shell by latch plate, and the impact of expanding and causing with compensating cylinder body heat, makes bull gear still keep original installation site; The utility model drives bull gear to turn round by little gear ring simultaneously, has good drive efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of tooth section in Fig. 1;
Fig. 3 is the generalized section of Fig. 2;
Fig. 4 is the structural representation after the utility model is installed.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figures 1 to 4, the split bull gear of a kind of cement rotary kiln of the present utility model, comprise bull gear 1, bull gear 1 is combined to form circular by some tooth sections 2, on tooth section 2 end faces, be provided with adjusting hole 24, tooth section 2 inside edges are provided with centre bore 23, and tooth section 2 outer ledges are evenly provided with the first sawtooth, and the two sides of tooth section 2 are provided with some connecting holes 22; Bull gear 1 is driven by the little gear ring 3 that is installed on bull gear 1 one sides, and little gear ring 3 outsides are provided with second sawtooth suitable with the first sawtooth.
In the present embodiment, tooth section 2 integral body are circular arc, the bull gear 1 of an annulus of each tooth section 2 formation capable of being combined; Thereby by by realizing the connection to adjacent two tooth sections 2 in the adjacent connecting hole 22 of adjacent two the tooth sections 2 of bolt 21 insertion, be connected with latch plate 25 on centre bore 23, the other end of latch plate 25 is installed on the cylindrical shell 4 of cement rotary kiln; The end face of tooth section 2 has two adjusting holes 24; The cross section of tooth section 2 sides is " work " font, and the two ends, left and right of " work " are all vertically provided with connecting hole 22.
In practical operation, when main motor rotation, drive 3 runnings of little gear ring, because little gear ring 3 and split bull gear 1 mesh completely, drive split bull gear 1 thereupon, make cement rotary kiln guarantee running.
The above is only preferred embodiment of the present utility model; be noted that for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
