TECHNICAL DATA


TRAVEL RATE

The stroke is determined by the ratio of the worm wheel screw jack. The standard ratio N produces 1mm of travel per one revolution of the input shaft, or worm. The input speed is 1,500 rpm, which is equivalent to a stroke of 1,500 mm per minute. The maximum input shaft speed is 1,800 RPM. Instead of the ratio L, a stroke of 0.25 mm is produced for each rotation of the input shaft. Based on an input shaft speed of 1,500 rpm, this ratio produces a speed of 375 millimeters per minute


LATERAL FORCE

Lateral forces can shorten the life of the screw jack and can cause product failure. The screw jack should be isolated from the lateral forces by the use of guide rails. Rotating or traveling nut-type worm gear screw jacks must be used in single jack applications without external guidance.


SELF-LOCKING FUNCTION

Trapezoidal screw jacks are self-locking. This function depends on various parameters including , but not limited to screw pitch, screw jack ratio, lubrication, vibration, mounting position, etc. It is necessary to brake or brake the motor to ensure the position is maintained. Please consult the Lude Transmission design process during use. Brakes are recommended for all applications involving vibration.


WORKING TEMPERATURES

Normal operating conditions are -20ºC to 80ºC. Please consult Lude Transmission for applications that require temperatures outside this range.
