The main advantages of Qipang rolling ring drives principle are:
1,highest possible efficiency due to the fact that the gear and the payload are completely supported by roller bearings
2,automatic traversing movement
3,variable traversing speeds ranging from 0 m/s to a maximum of 4.2 m/s; can also be separately set for the two directions with constant rotation of the shaft
4,variable traversing width and traversing position
5,high dynamics at the points of reversal
6,can be released from the shaft
7,low operating costs
8,low maintenance requirements
QP rolling ring drives - Easy to adjust pitch:
The pitch, or distance the nut moves per a single shaft revolution, is adjustable by changing the angle of the rings relative to the shaft. This is accompanied by a pitch control — usually a lever or a dial — on the housing.
Rolling ring drives manufacturers can design a linear motion system to permit pitch adjustment without slowing down the motor, and without making any other adjustments to controls. This is a production-boosting advantage should pitch adjustment become necessary during a production process. The system continues to operate while the operator tweaks the pitch to meet requirements. This feature helps rolling ring linear actuator users to maintain peak, or near-peak, production rates.
QP rolling ring drives - Maintenance is simple:
Besides periodic shaft lubrication, there are no routine maintenance procedures required with rolling ring systems. Over time, the wear on the drive shaft will make it necessary to replace it. And just like threads on a screw, the rolling ring drives can wear over long periods of continued use. Generally speaking, however, rolling ring linear actuators pay for themselves in time savings and lower maintenance costs well before significant maintenance or replacement is required.
Such actuators enable instantaneous automatic reversal of the traversing direction without the use of complex controls and without clutches, cams, or gears. Furthermore, the motor need not be slowed down or stopped to change traversing direction.
A mechanical lever affixed to the rolling ring drives nut is automatically “flipped” when the nut contacts its end stop, which may be adjusted to determine the length of the traverse before reversal. When the lever is flipped, it causes instantaneous reversal of the direction of traverse. Because no electronic controls or gear systems are involved, design time is less, maintenance is reduced, and operation requires no special training or skills.
The maintenance issue is one that merits consideration. The workhorse nature of these drives permits longer periods of continuous use of production machinery, which in turn helps make processes more productive and more profitable.
If you’re trying to move a very heavy load, say, one with a requirement of more than 800 lbs. axial thrust, a screw jack, hydraulic system, pneumatic setup, or some other method may provide the powerful axial thrust to meet such application requirements.
However, systems that just push against a load with unrelenting can cause problems if overload occurs. With rolling ring drives, the load is supported directly by the nut. As a result, side-thrust capacity can be tapped out with extremely heavy loads. But instead of continuing to push the load, slippage will occur. Slippage refers to the load-bearing nut being weighed down so heavily that it over compresses itself on the drive shaft and, as the shaft rotates, it simply slips through the ring bearings without causing linear motion — thereby providing overload protection.
QP rolling ring drives - Supporting the load
Screw-based and other types of non-rolling ring systems normally do not require the nut to bear the payload. Instead the load is attached to a carrier of some sort that incorporates its own supports and guide rails. This transfers moments of force from the nut to the load carrier and protects the system. The additional cost of fabricating the load-carrying device must be figured into the system development costs.
A rolling ring system typically has the load supported directly on the traversing nut. This means the user must pay heed to the risk of torque, or twisting the shaft, if the load is overhung or off center. In such applications, to remove moments of force from the nut, rolling ring drives actuators require an attachment called a linear slide to counter radial forces. The linear slide is a sturdy support system that is designed to carry the load. The slide is linked to the rolling ring actuator via a flexible coupling. Torque and bend forces are transferred to the slide, away from the actuator, thereby protecting the actuator and drive shaft.
