Design points of circular guide rails and synchronous belts

The design points of circular guide rails and synchronous belts involve multiple aspects, and the following is a detailed summary of the design points of both:

Design points of circular guide rail

1. Product features and advantages:

High rigidity and high positioning accuracy: The circular guide rail has the characteristics of high rigidity and high positioning accuracy, and is suitable for precision automation needs.

Good anti pollution ability: The bearing rolling elements in the roller do not directly contact the guide rail surface, and the bearing has good sealing performance, suitable for use in harsh environments.

Low maintenance and replacement costs: Worn rails or rollers can be replaced separately to reduce maintenance costs.

Adjustable preload: Adjust the preload force through eccentric rollers to ensure smooth operation.

2. Track layout form:

Linear guides and circular guides can be combined in different ways to achieve various track layouts, such as elliptical, rectangular, triangular, and irregular shaped layouts.

3. Driving mode:

Synchronous belt drive is a commonly used method with cost-effectiveness advantages. The servo motor drives the synchronous wheel to rotate, and the synchronous belt is connected to the slider to achieve the movement of the slider.

4. Determination of design parameters:

Determine the condition parameters in actual production, such as the load borne by the slider, the number of workstations, the distance between workstations, and the movement time of adjacent workstations.

Choose a suitable radius of arc guide rail to avoid more than one slider staying on the arc guide rail segment at the same time.

5. Connection method between synchronous belt and slider:

Slotted connection: Install slotted connection fasteners on the synchronous belt, which mesh with the metal pins on the slide.

6. Lubrication system:

Design a lubrication system to ensure sufficient lubrication of the guide rail working surface and increase system lifespan.

Design points of synchronous belt

1. Determine transmission parameters:

The basic parameters such as transmission power, transmission ratio, and speed are the basis for designing synchronous belt transmission systems.

2. Select synchronous belt type:

According to the characteristics and requirements of the transmission system, choose the appropriate type of synchronous belt, such as toothed synchronous belt, V-shaped synchronous belt, etc.

3. Calculate belt speed:

Calculate the belt speed of the synchronous belt based on the speed of the transmission system and the diameter of the pulley.

4. Determine bandwidth and bandwidth thickness:

Calculate the required bandwidth and thickness of the synchronous belt based on the transmission power and transmission ratio, taking into account factors such as load, tension, and operating conditions.

5. Determine the parameters of the pulley:

Based on the transmission ratio and belt speed, calculate the diameter and number of teeth of the pulley to ensure compliance with the size requirements of the synchronous belt and the accuracy of the transmission ratio.

6. Tensioning device design:

Design a suitable tensioning device to maintain the appropriate tension of the synchronous belt, considering load, speed, and adjustability.

7. Design of centering device:

Design a suitable centering device to maintain the parallelism and axis alignment between the synchronous belt and other transmission devices.

8. Verification and validation:

According to the design parameters, verify and validate to ensure that the synchronous belt transmission system meets the transmission requirements and working conditions, and has sufficient safety margin.

9. Consider other factors:

Working temperature, working environment, and service life are also important factors that need to be considered in the design process.

In summary, the design points of circular guide rails and synchronous belts involve multiple aspects, including product characteristics, track layout, driving mode, transmission parameters, belt width and thickness, pulley parameters, tensioning device, centering device, and verification. In practical design, it is necessary to comprehensively consider and select based on specific application scenarios and requirements.
