Usage Method
| Example of Use |  |  |  |
| Recommended Applications | Flat belt roller transfer mechanism It is connected to the roller to drive the flat belt to transport objects. | Timing pulley rotating mechanism It is connected to the timing pulley as a driven shaft to realize the function of reverse transmission. | Bearing and coupling rotating mechanism It is connected to the bearing and coupling to realize the function of forward transmission. |
Precautions
Rotary shaft selection method
STEP① Select the bearing support method
● Shaft end shape ～Please select tapped or retaining ring groove, etc. according to the fixing method～

Example of Use
Equipment name: Embedded fixture
Function description:
It is an embedded assembly fixture that can be embedded into rubber workpiece and aluminum workpiece, embedding the rubber convex part into the concave part of another workpiece. Load can be adjusted with bolt and compressed by roller.
Functions of rotary shafts in the mechanism
①The rotary shaft is used as a tightening connector in the mechanism, bearing the pressure applied by the spring, and connected to roller for compressing the workpiece.
②Excellent roundness and linearity, allowing the assembly fixture to apply force evenly, thereby improving overall stability of the tooling.
