AI Technical Summary

Technical Problem

The existing gearboxes for pulling machines are not compact enough and have low internal space utilization, resulting in large size and heavy weight, which is not suitable for use in narrow situations.

Method used

The bevel gear transmission assembly between the primary planetary transmission assembly and the secondary planetary transmission assembly is used for transmission, and the tooth shaft is designed as a hollow shaft. The secondary sun gear can directly pass through the connecting the secondary planetary transmission assembly from the inside of the tooth shaft.

Benefits of technology

It realizes the compactness of the overall structure, improves the utilization rate of the internal space of the box, reduces the weight of the gearbox and the required installation space size, making it more economical and suitable for more narrow occasions while ensuring the performance and reliability of the use, and is suitable for more narrow occasions.

Abstract

The invention relates to the technical field of gear boxes, in particular to a gear box for a withdrawal and straightening machine, which comprises an input mechanism, a gear transmission mechanism and an output mechanism, and the gear transmission mechanism is used for being matched with the input mechanism to adjust the power of the output mechanism; the gear transmission mechanism comprises a first-stage planetary transmission assembly, wherein the input end of the first-stage planetary transmission assembly is in transmission connection with the output end of the input mechanism. The first-stage planetary transmission assembly and the second-stage planetary transmission assembly are in transmission connection through the bevel gear transmission assembly, so that after the first-stage planetary transmission assembly and the second-stage planetary transmission assembly are matched, the overall structure is compact, meanwhile, due to the fact that the gear shaft is designed to be a hollow shaft, the transmission efficiency is improved; the secondary sun gear can directly penetrate through the interior of the gear shaft to be connected with the secondary planetary transmission assembly, the structure is more compact, the internal space utilization rate of the box body is further improved, and the weight of the gear box and the needed installation space size are greatly reduced.
