Product catalog summary
Overview of Cam Indexing Table: The document provides a comprehensive guide on the Cam Indexing Table by Hansheng Automation, detailing its components, operation principles, and maintenance requirements.
How Cam Indexer Works: The cam indexer operates by converting continuous rotary motion into intermittent motion. It involves components like the globoidal cam, cam follower, and turret, which work together to achieve precise indexing. The input shaft rotation causes the cam follower to move the turret along a displacement curve, ensuring smooth operation.
Specifications and Mechanism Principle: The document explains the mechanism principle, emphasizing the importance of smooth curves in motion diagrams to minimize vibration and noise. It categorizes motion diagrams into discontinuous, double stationary symmetric, double stationary asymmetric, single stationary, and non-stationary curves, each with specific applications based on speed and load requirements.
Order Code and Model Selection: The order code section provides guidelines for selecting the appropriate model based on torque load calculations. It highlights the importance of choosing the right model to prevent overload and ensure efficient operation.
Grease and Maintenance: Regular maintenance, including lubrication changes after 500-1000 hours of operation, is crucial for maintaining precision and extending the life of the index drives. The document advises against mixing different lubricant oils and stresses the importance of axial alignment in shaft connections.
How to Keep Precision: To maintain precision, the document suggests eliminating backlash by adjusting the distance between the input and output shafts and enhancing rigidity through appropriate preload adjustments.
Examples and Calculation: This section provides examples and calculations for selecting the correct cam curve, considering factors like maximum velocity, acceleration, and jerk. It also includes tables for life factor, expected life, and specifications of motion curves.
Assembly Notices: The document outlines the assembly process, including fixing methods for driven units and the importance of installing overload protection units to prevent damage.
Lubrication & Maintenance: Emphasizes the critical role of proper lubrication in maintaining accuracy and preventing wear. It advises regular lubricant changes and careful selection of lubricant types to avoid mixing different chemical compounds.
Specifications and Maintenance:
1. Safety devices are provided to prevent follower breakage. Abnormal noises indicate potential damage, requiring immediate operation cessation and inspection.
2. Regular checks every 5000 hours are necessary. Replace the follower if backlash is observed in the dwell range.
3. Proper lubrication is crucial. Lack of lubricant leads to damage, while excess can cause overheating or leakage. Lubricants should be replaced annually.
4. For high-speed drives, ensure connections between index drive shafts and torque mediators are secure.

Lubrication Guidelines:
1. Viscosity should be determined based on geometric average speed or high-frequency speed.
2. Use Petro China #90 oil with appropriate extreme pressure additives to enhance oil film strength and prevent corrosion.
3. Avoid mixing different lubricant types.
4. Replace lubricant after 500-1000 hours initially, then every 3000 hours.

Table Installation and Torque Specifications:
1. Table size should be based on permitted output torque load, with high precision requiring 2-3 times the torque.
2. Maximum table diameter should be five times less than the nominal dimension.
3. Index precision is influenced by offset when the table is installed.

Cam Curve Selection:
1. Cam curves impact accuracy and life of the cam segmentation mechanism. Options include modified sine, trapezoid, and constant velocity.
2. Selection depends on speed and load conditions, with modified sine being a versatile choice.

Use Examples and Calculations:
1. Detailed examples are provided for applying sub-tables and driving conveyors, including calculations for inertia, friction, and loading torque.
2. Safety factors and efficiency considerations are included in torque calculations.

Ordering and Model Specifications:
1. Model codes specify cam and turret assembly, output, input, and mounting positions.
2. Options for right or left-hand cams and various motion curves are available.
3. Hollow outputs for electrical and pneumatic connections can be specified.

Technical Parameters:
1. Allowable loads and torque on input and output shafts are specified.
2. Indexing accuracy and weight considerations are detailed.
Overview: This document provides detailed technical specifications and parameters for various mechanical components, focusing on torque, load capacities, and indexing mechanisms. It includes data tables and technical parameters for different models and configurations.
Key Sections:
  • Specifications: The document outlines specifications for different models such as 70DA, 90DA, 110DA, etc., detailing input and output shaft parameters, drive angles, and indexing accuracy.
  • Technical Parameters: Includes allowable thrust and radial loads on output and input shafts, maximum repetitive bending force, and torque values. These parameters are crucial for ensuring the components operate within safe limits.
  • Torque and Load Data: Tables provide values for static and dynamic torque, friction torque, and other mechanical forces. These are essential for understanding the mechanical performance and limitations of the components.
  • Indexing Mechanisms: Describes the indexing start and stop positions, drive angles, and the number of stops for various models. This section is critical for applications requiring precise motion control.
  • Mounting and Installation: Instructions for mounting positions, including special instructions for specific configurations, are provided to ensure proper installation and operation.
Data Interpretation: The tables and charts included in the document provide a comprehensive view of the mechanical capabilities and limitations of the components. Key data points include torque values, load capacities, and indexing accuracy, which are vital for engineers to design and implement these components effectively.

There are countless curves connecting two points in space. This is also true of the motion diagrams used for index drives, where there are innumerable curves connecting the starting point with the ending point. However, when designing a motion in indexing, it is necessary to use a curves as smooth as possible. To this end, vibration, noise and rigidity of materials should be taken into account. Also load and speed should be considered. After all factors are taken into consideration, curves emphasizing the characteristics of the speed, acceleration and jerk are usually used. Acceleration, especially...

If Vm is large, a great force will be exerted at the time of a sudden stop so a smaller Vm is usually preferred. Particularly if a load is heavy, it is necessary to select a curve with a smaller Vm. In addition, Vm is closely related to the size of a cam. Therefore, the size of a cam should be reduced accordingly if the curve has a small Vm. Also, Vm never becomes smaller than 1. In the case of a cam with a curve with a large Am, the maximum allowable load becomes small. So when it is driven at a high speed, it is necessary to select a curve with a small Am. In this case,, the Am is never smaller...
