Abstract
The utility model relates to a combined crushing tooth for a crusher. The combined crushing tooth for the crusher is capable of solving the problems that the brittle failure and the cracking occur in the prior art, the service life is short and the toughness is general. According to the to-be-solved technical scheme, the combined crushing tooth comprises a tooth ring body and tooth heads, wherein a shaft hole is formed in the center of the tooth ring body, helical convex bodies are uniformly distributed on the periphery of the tooth ring body, and the tooth heads are mounted on the helical convex bodies through bolts. The combined crushing tooth for the crusher has the advantages of simple structure, good tightness, convenience to mounting, dismounting and maintaining, good toughness and long service life and is an innovation on the crushing tooth.
Description
Technical field
The utility model relates to mechanical field, particularly the combined type crushing teeth used of a kind of disintegrating machine.
Background technology
Crushing teeth is the vital part of disintegrating machine, its performance quality directly determines the performance of disintegrating machine, require it that certain degree of hardness and certain toughness are arranged, at present, the wearability of potassium steel crushing teeth Yin Qigao commonly used is widely used in mining machinery on the market, fields such as metallurgy, but the development along with modern crafts, these fields have produced the more mining of high-wearing feature of a lot of requirements, broken, excavating equipment etc., traditional Technology for Heating Processing can not satisfy instructions for use, before using, potassium steel easily produces hot tearing, brittle failure can appear in the use, shortcoming such as burst apart and service life is short, and low-alloy quenched and tempered steel toughness is general, therefore, the improvement of crushing teeth is the problem of needing solution at present badly.
Summary of the invention
At above-mentioned situation, be to solve the defective of prior art, the purpose of the utility model just provides the combined type crushing teeth that a kind of disintegrating machine is used, can effectively solve prior art brittle failure appears, burst apart and service life short, the toughness general problem.
The technical scheme that the utility model solves is, comprises ring gear body and tooth head, and there is axis hole at ring gear body center, and uniform spiral helicine convex body is arranged on the ring gear body periphery, through bolt the tooth head is housed on the convex body.
The utility model is simple in structure, good airproof performance, and loading and unloading, easy to maintenance, good toughness, long service life is the innovation on the crushing teeth.
Description of drawings
Fig. 1 is structure master's pseudosection of the present utility model.
Fig. 2 is structure side pseudosection of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Provided by Fig. 1-2, the utility model comprises ring gear body 3 and tooth head 1, and there is axis hole 2 at ring gear body 3 centers, and uniform spiral helicine convex body 6 is arranged on ring gear body 3 peripheries, through bolt 4 tooth head 1 is housed on the convex body 6.
In order to guarantee result of use, there is the location to end button (not drawing among the figure) between described tooth head 1 and the ring gear body 3.
The blade-like that described tooth head 1 is made for alloy steel material.
Operating position of the present utility model is, formed by tooth head and denticle, denticle adopts normal steel casting, the tooth head adopts steel alloy, at first tooth head and denticle are cast after annealing, roughing, quenching, fine finishining more again, then tooth head and denticle are passed through bolt combination, thereby greatly reduce process-cycle and processing charges.Owing to there is the location to end button between tooth head and the denticle, cooperate tightlyer, when disintegrating machine moved, bolt did not stress substantially, prevents that better the tooth head from coming off.The combined type crushing teeth has easy to process, and cost is low, changes characteristics such as convenient, and the utility model is simple in structure, good airproof performance, and loading and unloading, easy to maintenance, good toughness, long service life is the innovation on the crushing teeth, has good economic and social benefit.
