1. Principle of servo electric cylinder:
Servo electric cylinder is a modular product designed to integrate servo motor and lead screw. It converts the rotary motion of servo motor into linear motion. At the same time, it converts the best advantages of servo motor-precise speed control, precise revolution control and precise torque control into precise speed control, precise position control and precise thrust control. New products to realize high-precision linear motion series.
2. Main components of servo electric cylinder:
1) Servo motor and driver
2), transmission mechanism (synchronous belt or gear)
3) Drive mechanism (ball screw)
4) Bearing device
5) Guide device
6), weighing sensor
7). Limit position sensing device
3. Calculation of servo cylinder output and selection of related accessories:
The formula for calculating the output of servo electric cylinder is as follows:
Servo electric cylinder output = rated torque * reduction ratio * transmission efficiency * 2/lead
1) The output is the maximum output required by theory (1T, 2T, 3T, etc.)
2) The reduction ratio is the speed ratio of the transmission mechanism, and it is possible to add a reducer
3), transmission efficiency refers to the overall transmission efficiency, general screw transmission efficiency is 90%
4), lead refers to the lead of the ball screw
4. Features of servo electric cylinder:
Closed-loop servo control, control accuracy of 0.01mm; precision control thrust, increase the pressure sensor, control accuracy of up to 1%; it is easy to connect with PLC and other control systems to achieve high-precision motion control. Low noise, energy saving, clean, high rigidity, impact resistance, long life, simple operation and maintenance. The servo electric cylinder can be trouble-free in harsh environments, and the protection level can reach IP66. Long-term work, and achieve high strength, high speed, high precision positioning, smooth movement, low noise. So it can be widely used in the automotive industry, electronics industry, mechanical automation industry, equipment assembly line industry.
Low-cost maintenance: The servo electric cylinder only needs regular grease injection and lubrication to work in a complex environment, and no wearing parts need maintenance and replacement, which will reduce a lot of after-sales service costs compared to hydraulic systems and pneumatic systems.
Configuration flexibility: it can provide very flexible installation configuration, with a full range of installation components: front flange, rear flange, side flange, tail hinge, trunnion installation, guide module, etc. Can be installed in line with servo motor or in parallel; Various accessories can be added: limit switch, planetary reducer, pre-tightening nut, etc. AC brake motor, DC motor, stepping motor and servo motor can be selected for driving.
5, the best alternative to hydraulic cylinders and cylinders:
The servo electric cylinder can completely replace the hydraulic cylinder and the cylinder, and realize the advantages of more environmental protection, more energy saving and cleaner. It is easy to connect with PLC and other control systems to realize high-precision motion control.
