Selection criteria for main components
It can perform correct linear motion and easy rotational motion, therefore ball splines are used.
Design Key Points
Calculation process of main components
Choose a motor that meets the load torque requirements.
Motor selection
Calculate load torque
Usage conditions: Drive synchronous toothed belt
Condition value:
Wheel diameter D=57.61 x 10 ⁻ ³ m
External force F=5N
The weight of the workpiece is W=0kg
Friction coefficient of sliding surface μ=0.1
Gravity acceleration g=9.8m/s ²
According to the load torque T=1/2 × D (F+μ Wg) N · m,
T=1/2×57.61×10⁻³×(5+0.1×0×9.8)=144×10⁻³ N·m
Select the type that satisfies the load torque T=144 × 10 ⁻ N · m
According to the torque characteristics of the selected motor MAMA012P1A, below 5000r/min
The continuous action range is 0.19N · m,
When the rated torque of the motor is greater than the actual applied torque, there is no problem.
Key points of construction, production, and design
By guiding the shaft and supporting the ball spline with bearings, smooth rotational motion can be achieved through key positioning.
Install sensors for vertical movement and rotation as needed.
