Description

Technical Field

[0001] The utility model relates to the technical field of rotary drive, in particular to a large-scale segmented rotary drive. Background Art

[0002] According to the transmission form, the slewing drive can be divided into gear slewing drive and worm gear slewing drive. The drive assembly of the slewing drive is usually used to install the motor. Since it does not need to bear the load, bearings are often used for rotation connection. However, the slewing assembly of the slewing drive often needs to bear a large load, so bearings cannot be used for rotation connection. Usually, the matching method of guide grooves and balls is used to realize the rotation function. However, there are some problems with the matching method of guide grooves and balls.

[0003] Traditional rotary drive devices are difficult to disassemble and maintain because the guide grooves and balls fit closely together, making disassembly difficult. At the same time, when the rotary drive is larger in size, the difficulty of disassembly and maintenance is further increased.

[0004] Therefore, a large-scale segmented rotary drive is needed to overcome the occurrence of the above-mentioned problems. Utility Model Content

[0005] In order to solve the above problems, the embodiment of the utility model provides a large-scale segmented rotary drive, which achieves the purpose of solving the problems raised in the background technology.

[0006] In order to achieve the above-mentioned purpose, the embodiment of the utility model specifically adopts the following technical scheme: a large-scale segmented rotary drive, including a plurality of fixedly connected assemblies, the assembly including an outer shell, the interior of the outer shell is rotatably connected to a driven gear through a rotary assembly, and a connecting block is installed on the driven gear; the rotary assembly includes a guide rail fixedly connected to the interior of the outer shell, a mounting seat fixedly connected to the connecting block, and a bolt roller bearing installed on the mounting seat and used in conjunction with the guide rail.

[0007] As a further improvement of the above technical solution:

[0008] The housing, the rotary assembly, the driven gear and the connecting block are combined to form an assembly; a driving assembly is installed on the housing of one of the assemblies.

[0009] The driving assembly comprises a driving seat arranged on the housing and a driving gear arranged on the driving seat; the driving gear and the driven gear are matched.

[0010] A sealing member located at the gap between the connecting block and the shell is installed on the top of the shell.

[0011] The beneficial effects of the embodiments of the utility model are:

[0012] The present application adopts a bolt roller bearing and a guide rail to achieve a rotational connection. When disassembling, it is only necessary to remove the bolt roller bearing from the mounting seat to complete the separation. Compared with the traditional guide groove ball matching method, the present application is less difficult to disassemble. At the same time, the rotary drive in the present application is composed of multiple assemblies fixed together, that is, a modular method is adopted, which is more convenient during assembly and disassembly.
