Concentrator reducer shares with you the application of high-precision low-backlash planetary reducer on CNC machine tools

The transmission source of CNC machine tools comes from servo electric motors. With the advancement of industry, electric motors have also been innovating in the direction of precision, high efficiency, simple control, and direction. Mechanical collocation has also progressed from traditional screw to precision ball screw. However, due to the processing of the machine tool, the conditions of the load feed system are quite different. It is necessary to add a reducer to increase the torque, improve the inertia matching at the load end, and make the feed run smoothly. Ordinary reducers have poor efficiency, large size, short life, and cannot be used for precise positioning control. Therefore, the use of high-precision and low-backlash planetary gear reducers is still the best match, which can eliminate the above-mentioned difficulties. CNC machine tools use high-precision low-backlash planetary gear reducer

Most of the planetary gear reducers with high precision and low backlash are used in the feed device. Because this type of reducer can withstand higher input speeds, it produces high torque density, high strength torsional rigidity, low backlash, and low noise value. , Easy to install, suitable for any assembly direction, the reduction ratio is sufficient and complete, so that the menu of the CNC machine tool now enters a more stable and more precise realm. The advantages of high-precision low-backlash planetary gear reducer are compact structure, small size, strong rigidity, and can produce high torque density. The coaxial input and output make the design more flexible and light in weight. High transmission efficiency above 96%, maintenance-free, long life, modular design, application and installation are easy, both forward and reverse rotation can be applied, good thermal conductivity, not easy to temperature rise, so it is the best choice for CNC machine tools.

Application examples

1. Machining center and CNC milling machine can use at least four or more.

X, Y axis feed and rapid feed can increase feed smoothness, reduce noise, and reduce the cost of servo motors. Due to the high torque, the control is easier, although the load is different, it does not affect the smoothness of the feed. Due to the gravity of the Z axis, the load on the up and down is completely different. The addition of a high-precision low-backlash planetary gear reducer can reduce the load of the servo motor and increase the life of the machine. The tool change mechanism requires fast speed, precise positioning, and low vibration. High-precision and low-backlash planetary gear reducers are still the best choice.

2. At least three pieces can be used for CNC lathes and turning centers.

X, Z axis feed and rapid feed, fast and smooth. High-precision low-backlash planetary gear reducer is used in conjunction with precision ball screws to reduce mechanical failure rate and improve precision. The servo-controlled high-low file conversion device shortens the time, and transfers files quickly and smoothly.

3. Digital grinder and electric discharge machine can use at least three pieces.

The X, Y, and Z three axes move smoothly at the same time, making the parameter setting of the controller easier, allowing the finished product to obtain high-precision, smooth arc contacts, and reducing the surface roughness.

A few explanations in practical applications

Due to the use of high precision and low backlash with precision ball screws, the control system is simple to set up and can produce high-precision products. The high-strength rigid structure has long service life, high efficiency, maintenance-free oil change, etc., so that mechanical failures are reduced. Since the gears are all ion-nitrided, the surface magnetic layer is wear-resistant, and the base material maintains its toughness. The hard cutting method, with less deformation and correct tooth profile, can produce high-precision, low-backlash planetary gear reducers.
