Description

Technical Field

[0001] The utility model relates to the technical field of parallel gearboxes, and particularly to an adjustable parallel gearbox. Background Art

[0002] As a common gear transmission device, the parallel gearbox has a wide range of applications in industrial machinery. It mainly consists of an input gear on the input shaft, one or more transmission gears, and an output gear on the output shaft. The advantage of the parallel gearbox is its compact structure, which can effectively save installation space and is suitable for application scenarios with strict space requirements.

[0003] However, in the existing design of parallel gearboxes, there are some technical challenges to overcome. One significant problem is the fixation of the transmission gears. Due to manufacturing tolerances and wear during long-term use, the transmission gears may shift or become loose, thus affecting the normal meshing between the gears. Once this occurs, traditional parallel gearboxes usually do not have an effective mechanism to adjust or correct the position of the transmission gears, which will lead to a decrease in transmission efficiency, an increase in noise, and even premature failure of the entire gear system.

[0004] In addition, repairing or replacing worn transmission gears often requires disassembling the entire gearbox, which not only increases the maintenance cost but also may lead to an extended production downtime, thereby affecting the overall production efficiency. Summary of the Utility Model

[0005] The utility model aims to at least solve the technical problems existing in the prior art. For this purpose, the utility model provides an adjustable parallel gearbox, which can adjust the position of the transmission gears to enable the normal meshing of the transmission gears with the input gear and the output gear, effectively reduce noise, and ensure that the entire gear system will not fail prematurely.
