★High load capacity.The planetary roller screw is in line contact, and the increase of the contact surface greatly improves the load-bearing capacity and rigidity. Therefore, it has high rigidity and high load capacity, which is more than 3 times higher than that of the same specification ball screw pair (the highest is more than 10 times).
★Shock proof: The ability to withstand impact loads is strong and work reliably.
★small volume: Under the same load, the volume of the planetary roller screw is 1/3 smaller than that of the ball screw.
★High speed: The maximum linear speed can reach 2000mm/s, and the input rotation speed can reach 5000rpm or higher. The maximum acceleration can reach 3g.
★Low noise: It avoids the restriction of the return device on the DN value, and realizes high-speed driving under the condition of small lead, DN≥140,000, Vmax≥60m/min, angular acceleration 7.000r/s2, low vibration and low noise.
★High precision: The screw shaft is a non-circular thread with a small lead angle, which is conducive to achieving higher lead accuracy and can realize precise micro-feed. Lead accuracy, KL5=±0.005mm, lead accuracy KL10 (standard)=±0.01mm. (315mm stroke)
★Long life: The static load that the planetary roller screw can bear is 3 times that of the ball screw, and the life is 15 times that of the ball screw.
■The integrated nut assembly is easily separated from the screw shaft, and the rolling elements and related parts will not be scattered, which is convenient for installation and maintenance.
■Strong adaptability to harsh environments (low temperature, dust, chemical deposition, no lubrication, etc.).
●Nut form: single nut, double nut, pre-tightening nut, etc.
Q：What is trapezoidal screw?A：Trapezoidal screw is a kind of lead screw. It is a trapezoidal screw thread. Generall, a 30-degree trapezoidal screw means that the angle of the thread section extension is 30 degrees. Trapezoidal screws are divided into left-handed, right-handed and bi-directional-handRead More
What are the advantages of linear modules? The linear module is an automatic transmission element, which uses timing belt or ball screw to drive the slider to move. It is usually composed of timing belt, ball screw, direct moving die, aluminum alloy profiles, ball screw bracket, coupling, motor, PhoRead More
We all know that linear guides are now an important part of mechanical equipment. Be careful when using linear guides. Many factors will affect the guides and make them fail during operation! Today I will introduce you to the influence of temperature on linear guides! The influence of temperature oRead More
The relationship between the pre-pressure of the ball screw and the load of the screw is mainly used for gap adjustment. If high precision is required, the pre-pressure should be increased accordingly, but it should not be too large, otherwise it will cause high temperature and reduced efficiency.Read More
What is the ball screw drive torque? How should this torque be calculated? The torque of the mechanical components is called the driving torque of the ball screw. The ball screw will produce a certain degree of torsional deformation under the action of torque. Torque is the basic load form of transmRead More
Features of Rotating SeriesZero clearance in spline rotation direction/high positioning accuracyThe contact angle between the nut and the steel ball is 40°, and the bearing DB type (back-to-back combination) design is adopted. Due to the wide span between the effective centers of the bead groove, thRead More
