Description
Technical Field
The utility model relates to a reducing mechanism technical field, concretely relates to a stator ring gear that is used for powder mechanical mill to trade tooth.
Background
In recent years, the powder industry in China has rapidly grown with the development and popularization of powder technology. In particular, in the lithium battery material crushing industry, the superfine crushing and grading technology has begun to be developed on a large scale.
Powder with a particle size of 0.1-10 um is generally called as ultrafine powder, and the preparation of the ultrafine powder mainly comprises a mechanical grinding method and a chemical synthesis method. The chemical synthesis methods include coprecipitation, hydrolysis, sol-gel, hydrothermal, gas-phase reaction, and solvent methods, and laser methods (e.g., synthesis of BaTiO and powder) have been developed. The chemical synthesis method has high cost, small production scale and complex process, and adopts mechanical crushing method mostly except a few ultrafine powders, so that the mechanical crushing method has low production cost, high yield and simple process, can generate mechanochemical reaction, is possible to improve the performance of materials and is easy to realize large-scale production. The mechanical impact mill is one of the products of mechanical crushing equipment, and a stator gear ring is arranged in the mechanical impact mill and is used as a main crushing and grinding part. The principle of crushing is that the coarsely crushed materials are placed into a mechanical grinding cavity, impacted by a hammer head, impact a tooth part of a stator gear ring and are ground and sheared by the materials, so that the materials are subjected to volume crushing and surface crushing, and finally, the materials which are crushed properly are selected out and collected. Because the gear ring of the grinding cavity stator is subjected to impact grinding for a long time, the tooth part of the gear ring is easy to wear, so that the grinding efficiency is reduced, and worn fragments are easy to mix into materials to cause pollution and influence the product quality. Therefore, the stator gear ring needs to be replaced regularly according to the abrasion degree of the stator gear ring so as to ensure the product quality.
But present ring gear and ring gear tooth portion are mostly the integral type structure, and this just causes and also needs a whole set of change ring gear when few ring gear heads wear and tear, causes the wasting of resources, and sometimes because of the particularity of smashing the material, can require the ring gear to be special material, and is high in price, so partial change can be the optimum solution.
The prior art discloses a patent of CN201445979U, which includes a base ring and a set of racks, wherein a set of tooth grooves for fixing the racks are provided inside the base ring, and each rack is located in a corresponding tooth groove. The tooth grooves of the rack and the base ring are fixedly connected in a separable mode (can be formed by one-time pressing in an injection molding (hot pressing) mold according to needs, and can also be firmly bonded by adopting a high polymer material).
The above-mentioned devices, along with their use, also gradually reveal the deficiencies of this technology, mainly in the following aspects:
first, if the base ring is different from the tooth part in material, when the base ring is connected by adopting a bonding mode, a proper bonding agent is difficult to find, so that the tooth part is loosened and even falls off in the using process.
Secondly, if the contact surface of the base ring matched with the tooth part is not machined, the contact surface has insufficient fitting degree, and the probability of loosening the tooth part is increased.
The prior art discloses a patent CN212663725U, which comprises a gear ring, a gear ring head and a machine cover, wherein the gear ring is provided with a convex part; the gear ring head is provided with a concave part matched with the convex part, and the gear ring head is arranged on the gear ring through the matching of the concave part and the convex part.
The above-mentioned devices, along with their use, also gradually reveal the deficiencies of this technology, mainly in the following aspects:
in order to ensure the tight fit of the gear ring and the gear ring head, strict tolerance control is adopted, so that the gear ring head which needs to be subsequently replaced also needs to be precisely machined, and if the gear ring head is made of special materials such as tungsten carbide, zirconium oxide and the like, the cost of the gear ring head is greatly increased.
In view of the above, the prior art is obviously inconvenient and disadvantageous in practical use, and needs to be improved.
