The connection between the timing belt and the slider in a ring guide rail is mainly an open-slot connection. It is fixed through engagement between a fastener and a metal pin. Different brands, such as Kubik, optimize the structure with screw fixation, pin torque design, and other improvements.
Open-Slot Connection (General Design)
Connection principle: An open-slot fastener is mounted on the timing belt. The metal pin on the slider engages with the long slot of the fastener to form a fixed connection.
Function of the long slot: It accommodates slight offset when the slider changes from linear motion to curved motion, preventing connection failure or jamming caused by trajectory changes.
Kubik Ring Guide Rail Optimization
Based on the general open-slot connection, Kubik further optimizes the fixation between the slider and the timing belt:
Fixed spacing design: The timing belt and all sliders are pre-fixed. Slider spacing is precisely controlled by the center distance parameter and can be customized according to customer needs, ensuring stable synchronous operation of multiple stations.
Screw fixation: Pins are set on the timing belt, and brass blocks are installed at corresponding positions on the slider. The two are locked by screws to increase connection rigidity.
The lower end of the pin bears tension and generates torque during movement. A wider timing belt is needed to disperse stress and prevent local deformation.
High-precision secondary positioning: Clearance is reserved at the contact points between the timing belt and the driving and driven pulleys. Cylinders on both sides enable precise fine adjustment to compensate for transmission errors and improve positioning accuracy.
Torque dispersion design: A wider timing belt firmly fixes the pins with screws, avoiding loose connections or belt breakage caused by concentrated torque during movement.
Core Advantages of the Connection Method
Synchronization guarantee: Fixed spacing and rigid connection ensure synchronous movement of multiple sliders, suitable for circulating assembly lines, rotary inspection, and similar scenarios.
Motion flexibility: The open-slot design allows slight offset, adapts to the curved path of the ring guide rail, and reduces wear.
High-precision adaptability: Kubik's secondary positioning and torque dispersion design meet strict precision requirements in electronics, coating, and other industries.
Application Scenarios
The timing belt-slider connection structure of ring guide rails is widely used in food packaging, automatic marking, logistics sorting, and other industries. Its compact design significantly saves space, while multi-station synchronization improves production efficiency. For example, in electronic component inspection, multiple sliders can carry test items at the same time and complete inspection and sorting processes sequentially along a ring path. We can provide ring guide rails, timing belts, and other machined parts for these applications.
