Non-hollow and low-noise robot uniaxial structure

Abstract

The invention relates to the technical field of robots, in particular to a non-hollow and low-noise robot uniaxial structure. The non-hollow and low-noise robot uniaxial structure comprises a robot base, a uniaxial rotary seat, a reducer, a servo motor, a cable cavity and robot cables, wherein the uniaxial rotary seat is arranged on the robot base, the reducer is connected with the robot base andthe uniaxial rotary seat, the servo motor is arranged on the robot base and connected with the reducer in an inserted manner, the cable cavity is formed in the robot base, and the robot cables are arranged in the cable cavity; the servo motor is in drive connection with the reducer; the cable cavity is arranged around the servo motor to allow the robot cables to be fixed in the cable cavity in a surrounding manner. The non-hollow and low-noise robot uniaxial structure has the advantages that due to the fact that the servo motor is in direct transmission connection with the reducer, the robot uniaxial structure is simple, high in transmission efficiency, low in noise, easy to assemble and convenient to maintain; in addition, due to the fact that the robot cables can be arranged in a surrounding manner, accessories such as an air pipe and an IO signal line can be added conveniently, the use of a gear for winding the cables is avoided, and cost is lowered.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a non-hollow low-noise robot one-axis structure. Background technique [0002] The one-axis structure of the traditional six-axis robot needs to arrange the robot servo motor cable, so it mainly adopts the structure of the gear transmission hollow reducer. This structure will cause the noise of the one-axis structure of the robot to be large. Grease is injected into the gears. Although injecting lubricating grease into the gear can reduce noise, it is easy to cause oil leakage, and the maintenance cost of oil leakage is relatively high, and the assembly of this robot one-axis structure in the prior art is also very difficult, thus seriously affecting Productivity. [0003] In addition, in the one-axis structure of the six-axis robot in the prior art, the cables are generally wound around two gears, so oil seals and bearing connections are required, which leads to relatively high...

[0002] The one-axis structure of the traditional six-axis robot needs to arrange the robot servo motor cable, so it mainly adopts the structure of the gear transmission hollow reducer. This structure will cause the noise of the one-axis structure of the robot to be large. Grease injected into gears

Although injecting lubricating grease into the gear can reduce noise, it is easy to cause oil leakage, and the maintenance cost of oil leakage is relatively high, and the assembly of this robot one-axis structure in the prior art is also very difficult, thus seriously affecting Productivity

[0003] In addition, the one-axis structure of the six-axis robot in the prior art generally has cables wound around two gears, so oil seals and bearing connections are required, which in turn makes the cost relatively high

Moreover, this method of setting cables in the prior art is also not conducive to adding accessories such as air pipes and IO signal lines.
