Description

Sectional type ultra-large gear ring convenient to disassemble and assemble

Technical Field

The utility model relates to a ring gear field, concretely relates to sectional type ultra-large gear ring convenient to dismouting.

Background

The ultra-large gear ring is very common in the mechanical industry, for example, the figure of the ultra-large gear ring can be seen on large equipment such as a ball mill, a rotary kiln and the like, the application is very wide, however, the size of the ultra-large gear ring is limited by the size limitation of machining equipment, at present, the conventional machining equipment is difficult to machine for the ultra-large gear ring, and even if the ultra-large gear ring is machined by an ultra-large machine tool, the transportation and installation of the ultra-large gear ring are difficult in the later period.

Based on this, all adopt the sectional type design to super large-scale ring gear in the trade at present, cut apart into a plurality of sections single-stage ring gears to a whole ring gear, single-stage ring gear is small, and ordinary machine tool just can process, and the transportation is also very convenient, only need later stage with a plurality of sections single-stage ring gear assemble into complete ring gear can, very convenient. The chinese patent with application number 201410085773.4 in the prior art discloses a combined segmented herringbone ring gear.

However, in the actual use process, the assembly of the single-section gear ring is always difficult for the sectional type ultra-large gear ring, and the assembly process is somewhat careless, for example, the single-section gear ring is not aligned, the bolt is not screwed down, and the like, which causes the teeth of the assembled ultra-large gear ring to be misaligned, and the work cannot be performed.

At present, the conventional assembly mode is that holes are punched at two ends of a single-section gear ring basically, and then the two single-section gear rings are fixedly connected by bolts through connecting plates, for example, as shown in the combined type subsection herringbone inner gear ring disclosed in the prior patent, the bolt connection mode has the defects that the assembly is too laborious, because the diameter of the ultra-large gear ring is generally from a few meters to a dozen meters, and the larger the diameter of the gear ring is, the more the number of divided sections is, the longer the time taken for assembling is, meanwhile, the more the number of the sections is, the larger the error in the assembling process is, the more difficult the two single-section gear rings are connected together, therefore, when in assembly, the multi-section single-section gear rings are connected to form a whole gear ring, the teeth are aligned, and then the bolt can be screwed, meanwhile, when the bolts are screwed, one bolt cannot be screwed down again after one bolt is screwed down, so that the aligned teeth are easy to deviate, and manpower and material resources are consumed.

Based on this, it is necessary to improve the connection mode of the existing single-stage gear ring.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

When the gear ring is an inner gear ring, as shown in fig. 1-8, the sectional type ultra-large inner gear ring convenient to disassemble and assemble provided by the utility model comprises a plurality of single-section gear rings 1, two adjacent single-section gear rings 1 are in mortise-tenon connection, the mortise-tenon connection is simple and convenient to disassemble and assemble, time and labor are saved, the connection positioning precision is not worse than that of the conventional bolt connection, the tenon 2 and the mortise 3 can be ensured to be stable and not shake after the mortise-tenon connection of the two single-section gear rings 1 when the single-section gear ring 1 is processed according to the design requirement and the size, and the connection positioning is accurate and reliable;

specifically, one end of each single-section gear ring 1 is provided with a tenon 2, the other end is provided with a mortise 3, the tenon 2 and the mortise 3 are connected with the outer circular surface of the single-section gear ring 1, the tooth is positioned on the inner circular surface of the single-section gear ring 1, the tenon 2 and the mortise 3 are not contacted with the tooth and two end surfaces, so that when the sectional type ultra-large gear ring is assembled, only one single-section gear ring 1 can be moved to the center of the gear ring along the radial direction, the tenon 2 of one single-section gear ring 1 can be inserted into the mortise 3 of the other single-section gear ring 1, when the sectional type ultra-large gear ring is disassembled, only the single-section gear ring 1 can be moved along the direction shown by the arrow in figure 1 (namely the radial direction of the gear ring and far away from the center of the gear ring), the mechanical strength of the tenon connection of the tenon and mortise 1 is not worse than that of the bolt connection, because the outer circular surface of the inner gear ring is generally attached to a workpiece 4, as shown in FIG. 2, because one single-section gear ring 1 can only be separated from other single-section gear rings 1 by moving along the direction shown by the arrow in FIG. 1, the existence of the mounting workpiece 4 just limits the movement of the single-section gear ring 1, so that the sectional type ultra-large inner gear ring becomes a stable and high-mechanical-strength whole.

Compared with conventional bolt fixed connection, the tenon-and-mortise connection not only keeps the connection strength and the connection precision constant and is not reduced, but also is greatly convenient to disassemble and assemble, the trouble of spending a large amount of time on screwing bolts is eliminated, and the practicability is good.

When the gear ring is an external gear ring, referring to fig. 9-15, the sectional type ultra-large external gear ring convenient to disassemble and assemble provided by the utility model also comprises a plurality of single-section gear rings 1, and two adjacent single-section gear rings 1 are in mortise-tenon connection;

specifically, one end of each single-section gear ring 1 is provided with a tenon 2, the other end of each single-section gear ring is provided with a mortise 3, the tenon 2 and the mortise 3 are connected with the inner circular surface of the single-section gear ring 1, the tooth is positioned on the outer circular surface of the single-section gear ring 1, and the tenon 2 and the mortise 3 are not in contact with the tooth and two end surfaces, so that when the sectional type ultra-large outer gear ring is assembled, only one single-section gear ring 1 can be moved away from the center of the gear ring along the radial direction of the gear ring to insert the tenon 2 of one single-section gear ring 1 into the mortise 3 of the other single-section gear ring 1, and when the sectional type ultra-large outer gear ring is assembled, the tenon 2 of one single-section gear ring 1 can only be moved away from the mortise 3 of the other single-section gear ring 1 along the direction (namely the radial direction of the gear ring and towards the center of the gear ring) shown by an arrow in figure 9, so that the design ensures that the mechanical strength of the tenon, as shown in FIG. 10, because one single-stage gear ring 1 can only be separated from other single-stage gear rings 1 by moving along the direction shown by the arrow in FIG. 9, the existence of the mounting workpiece 4 just limits the movement of the single-stage gear ring 1, and the segmented ultra-large outer gear ring becomes a stable and high-mechanical-strength whole.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
