Description

Technical Field

[0001] The invention belongs to the technical field of couplings, and more specifically, relates to a method for optimizing a series of drum gear coupling products, and a method for selecting the products obtained after the optimization. Background Art

[0002] At present, there are many types of conventional drum gear couplings, and the management of coupling product standards is chaotic. Each industry has its own industry standards. For example, the metallurgical industry currently has several product standards in use, such as GⅠ / ⅡCL, GⅠ / ⅡCLZ, GCLD, NGCL, NGCLZ, WGPⅠ, WGPⅡ, WGPⅣ, WGPⅤ, WGT and other 12 structures and a total of 208 specifications. Therefore, there are problems such as inconsistent product structure types, too many specifications resulting in low versatility and interchangeability of parts, resulting in a long cycle time from design (determining the structure and specifications of the product) to production, and the market demand for rapid delivery of the product cannot be met.

[0003] At the same time, the existing conventional drum gear coupling standards are not divided according to the actual operating conditions of the product, resulting in the selection specifications being too large or too small when selecting according to the standards, causing the selection results to fail to meet the use requirements, or the selection results to be too safe and cause a waste of resources. Summary of the invention

[0004] The problem to be solved by the present invention is to provide an optimization method for a series of drum gear coupling products, which reduces the structure and specifications of the drum gear coupling products, thereby improving the efficiency of selection and shortening the manufacturing cycle, thereby meeting the demand for rapid delivery. At the same time, the present invention provides a product obtained based on the above optimization method. In addition, the present invention also provides a method for selecting the above products, which can be reasonably selected according to the actual use conditions of the products.

[0005] The optimization method of the drum gear coupling series products of the present invention comprises the following steps: step 1, sorting out and analyzing the structure of the domestic relevant drum gear coupling standards and the actual usage of customers, optimizing them into a basic structure and seven deformation structures, and forming a new drum gear coupling series products (hereinafter referred to as G series products); step 2, optimizing the specifications of the above-mentioned existing structures, determining the specific specifications of each product in the G series products, and obtaining all the specifications of the products.

[0006] Among them: In step one: there are twelve domestic related drum gear couplings, namely GIICL and WG standards: GIICL includes GⅠCL, GⅡCL, GⅠCLZ, GⅡCLZ, GCLD, NGCL and NGCLZ; WG includes WGPⅠ, WGPⅡ, WGPⅢ, WGPⅣ and WGT.

[0007] Among them: In step one: the basic principle of optimization is to cover the largest scope with the least standards: that is, on the basis of the existing twelve product standards, some special parts structures are eliminated, and some parts structures with high commonality, wide coverage and high degree of standardization are sorted out to form a half-coupling (standard, non-standard), bushing, brake wheel, brake disc, intermediate sleeve, a total of six basic parts, which are combined to form a basic structure and seven deformation structures of the G series products.

[0008] Among them: In step one: G series products are specifically: G base type, GZT shaft sleeve type, GD motor shaft type, GL brake wheel type, GLZ brake wheel shaft sleeve type, GP brake disc type, GPZ brake disc shaft sleeve type, GT intermediate sleeve type.

[0009] Among them: In step 2: a total of 208 specifications of twelve standards of GIICL and WG are used as references and optimized. The basic principle of optimization is to cover the largest range with the least standards: that is, on the premise of meeting the use requirements, similar specifications are integrated, and specifications that are too large or too small are eliminated, and specifications with high commonality and wide coverage are sorted out, forming a total of 172 specifications of eight structures of G series products, covering the following ranges: flange diameter D from φ103 to φ1060, nominal torque from 0.63KN.m to 1750KN.m, and maximum speed of 6700r / min to 900r / min.

[0010] The product obtained by the optimization method of the present invention comprises a G base type, a GZT shaft sleeve type, a GD motor shaft type, a GL brake wheel type, a GLZ brake wheel shaft sleeve type, a GP brake disc type, a GPZ brake disc shaft sleeve type and a GT intermediate sleeve type; wherein the G base type is a combination of two standard half-couplings, the GZT shaft sleeve type is a combination of a standard half-coupling and a shaft sleeve, the GD motor shaft type is a combination of a standard half-coupling and a non-standard half-coupling, the GL brake wheel type is a combination of a standard half-coupling and a brake wheel, the GLZ brake wheel shaft sleeve type is a combination of a standard half-coupling, a brake wheel and a shaft sleeve, the GP brake disc type is a combination of a standard half-coupling and a brake disc, the GPZ brake disc shaft sleeve type is a combination of a standard half-coupling, a brake disc and a shaft sleeve, and the GT intermediate sleeve type is a combination of a standard half-coupling and an intermediate sleeve.

[0011] Furthermore, the half coupling includes an outer gear sleeve, an inner gear ring, and a pressure cover. The outer gear sleeve and the inner gear ring are meshed through a gear pair. The pressure cover is sleeved on the outer gear sleeve and connected to the end face of the inner gear ring through a connecting piece.

[0012] Furthermore, when the inner gear ring is a short inner ring, it is a standard inner gear ring, and its corresponding half coupling is a standard half coupling; when the inner gear ring is a long inner ring, it is a non-standard inner gear ring, and its corresponding half coupling is a non-standard half coupling.

[0013] Furthermore, the inner gear ring adopts a stopless fit and is connected by bolts with reamed holes to achieve the interchangeability of two inner gear rings of the same series.

[0014] The present invention provides a method for selecting a drum gear coupling, which comprises the following steps: step one, collecting and analyzing the use conditions of the product, and determining the specific structure of the G series product based on "production line type, region, equipment / components, load category, rotation speed, temperature, deflection angle", etc.; step two, calculating the calculated torque of the coupling based on the motor power, motor rotation speed, reduction ratio, and motor output form, and combining the coupling shaft hole diameter parameter to determine the specific specifications of the product; step three, combining the requirements of the coupling life, determining the processing level of the basic parts in the specific structure of the G series: including materials, precision levels and processing technology, and forming a corresponding configuration table; step four, calculating the torque and rotation speed corresponding to the product according to the material and precision level of the meshing gear pair, reviewing the rationality of the selection of the structure and specification, avoiding the selection result being too large or too small, and achieving the economy and applicability of the selection.

[0015] The advantages of the optimization method of the present invention are: it classifies, optimizes the structure, specifications, and common parts of the two parallel standards of the GIICL and WG industries, and forms a new series of drum gear coupling product standards: the series of products are basic structures and 7 deformation structures, 172 specifications, thereby reducing the specifications of the original standards, the types and quantities of parts, improving the standardization rate of products, improving the efficiency of design selection, shortening the manufacturing cycle, and meeting the needs of rapid delivery. At the same time, the selection method of the present invention performs reasonable selection according to the actual use conditions of the product, which not only avoids the selection results failing to meet the use requirements, but also avoids the waste of resources due to the selection results being too safe.
