The first shaft gear 221 of the present invention uses the second shaft gear 241 to support the first rounded support end 2213 of the first shaft gear 221, so the static point support state of the point support can be effectively achieved, and the The rotational friction force between the first shaft gear 221 and the second shaft gear 241 is reduced to approach zero.

Similarly, since the rotation speed of the second shaft gear 241 and the revolution speed of the second planetary gear 242 will also have a speed difference due to the different gear ratios, the weight of the entire second reduction planetary gear assembly 24 will be concentrated on the center of the second planetary gear assembly 24. The two-axis gear 241, and because the present invention uses the second rotating frame base 2431 to support the second rounded support end 2413 of the second-axis gear 241, the static point support state of point support can be effectively achieved, and the first The rotational frictional force between the two-axis gear 241 and the second rotating frame base 2431 is reduced to approach zero.

Among them, since the structure of the direct-type deceleration transmission mechanism 2a is the same as that of the direct-type deceleration transmission mechanism 2, the structure of the motor 3a is the same as that of the motor 3, and the structure of the grinding cylinder assembly 5a is the same as that of the grinding cylinder assembly 5, so in this embodiment, only the The direct-drive reduction transmission mechanism 2 , the motor 3 and the grinding drum assembly 5 will be described.

In the present embodiment, the transmission assembly 4 includes a transmission member 41 and a toothed plate 42 , the toothed plate 42 is rotatably disposed on the grinding equipment base 1 , and the transmission member 41 is drivingly connected to the toothed plate 42 and the direct-drive reduction gear.

The grinding cylinder body 52 is fixed to the support plate body 512 . Therefore, when the motor 3 operates and rotates, after the rotation of the motor output shaft 311 is decelerated in two stages through the direct-type deceleration transmission mechanism 2, a large rotational torque will be transmitted through the transmission assembly 4 to drive the grinding cylinder assembly 5. By rotating, the abrasive disposed in the grinding cylinder body 52 can be driven to grind the workpiece to be ground deep into it.

To sum up, compared with the grinding equipment of the prior art, in order to effectively change the output mode of the motor with high speed and low torque to the output mode of low speed and high torque, it is usually necessary to use a planetary gear assembly. When a plurality of planetary gear assemblies are installed, the transmission connection between the plurality of planetary gear assemblies is carried out through transmission parts, resulting in a need for a large installation space to install the plurality of planetary gear assemblies, which is very inconvenient; The fixed gear meshing cylinder is used to mesh the first reduction planetary gear assembly and the second reduction planetary gear assembly, so that the first reduction planetary gear assembly and the second reduction planetary gear assembly can be overlapped and arranged in the fixed gear meshing cylinder, In order to effectively achieve the effect of using a plurality of planetary gear assemblies, the required space can be effectively achieved, so that the grinding equipment and the direct-type reduction transmission mechanism of the present invention can be more conveniently arranged in the grinding working space, which is very convenient.
