PMI GROUP was established in 1990. It’s highly involved in manufacturing of ballscrews, precision ball screw spline, linear guideway, ball spline and actuator, which is the critical component of precision machinery and mainly applied to Machine Tool, El
Ball Screw The Ball Screw is a high-efficiency feed screw with the ball making a rolling motion between the screw axis and the nut. Compared with a conventional sliding screw, this product has drive torque of one-third or less, making it most suitable for saving drive motor power....
This ball screw provides low noise, small torque fluctuations and long-term maintenance-free operation by adopting caged ball technology. [Model number]SBN-V/SBN, SBK, HBN, SDA-V, SBKH CAD Service life calculation(Ball screw) Details / Product lineup Finished Shaft Ends Model BNK This mod...
Notes: "Slenderness" is the value of dividing the outside diameter of the screw shaft by the threading length. For reference torque less than 2 kgf * cm, TBI Motion specifications will apply. Table 7: Permissible Ranges of Torque Variation Rates Calculation of Reference Torque Tp The equation...

PROBLEM TO BE SOLVED: To provide a ball screw device which can prevent the contact of a piston and a clutch at the block of power. W Atsushi,渡邊 篤 被引量: 0发表: 2016年 APPLICATION OF BALL SCREW AND SLITTED DISC FOR OVER-LOAD CLUTH Friction,abrasive wear,transfer torque properties of...
The variation tendency of the film thickness is similar to that of the screw speed, while the evolution of the friction torque at ball-screw interface is dependent on the ball spin speed. Compared to the ball-nut interface, the friction coefficient is higher on the ball-screw interface. ...
