Product catalog summary
Overview of Cam Indexing Table:
This document provides a comprehensive guide on the Cam Indexing Table by Hansheng Automation, detailing its working mechanism, specifications, maintenance, and model selection.

1. How Cam Indexer Works:
The cam indexer uses a globoidal cam on the input shaft interacting with a turret on the output shaft. The cam follower ensures smooth motion, with adjustments available to eliminate backlash and enhance rigidity.

2. Specifications and Mechanism Principle:
Key terms include indexing cam, drive angle, dwell angle, and torque. The document emphasizes smooth motion curves to minimize vibration and noise, highlighting acceleration and jerk's role in indexing accuracy.

3. Motion Diagrams and Curves:
Discusses motion curves like discontinuous, double stationary symmetric, and asymmetric curves, affecting velocity, acceleration, and jerk, impacting performance and load capacity.

4. Types of Drives:
Describes indexing, oscillating, and roller drives, each with specific operational characteristics. Indexing drives operate intermittently, oscillating drives allow bidirectional rotation, and roller drives offer stable rotation without backlash.

5. Model Selection and Assembly:
Guidelines for model selection based on torque load calculations are provided, along with assembly notices emphasizing smooth input shaft rotation to prevent overload.

6. Maintenance and Lubrication:
Regular maintenance, including lubricant changes, is crucial for longevity and accuracy. The document warns against mixing lubricants and stresses eliminating backlash.

7. Safety and Overload Protection:
Overload protection devices are essential to prevent damage and ensure safety, with torque limiters recommended for maintaining normal operation.

Specifications and Maintenance:
Safety devices prevent follower breakage, with regular checks every 5000 hours. Proper lubrication is crucial, with annual lubricant replacement recommended.

Lubrication Guidelines:
Viscosity should be based on speed, using Petro China #90 oil with additives. Avoid mixing lubricants and replace them after initial 500-1000 hours, then every 3000 hours.

Table Installation and Torque Specifications:
Table size should match output torque load, with high precision requiring 2-3 times the torque. Maximum table diameter should be five times less than the nominal dimension.

Cam Curve Selection:
Cam curve impacts accuracy and life, with options like modified sine, trapezoid, and constant velocity. Selection depends on speed and load conditions.

Use Examples and Calculations:
Examples for applying sub-tables and driving conveyors include calculations for inertia, friction, and loading torque, with safety factors and efficiency considerations.

Ordering and Model Specifications:
Model codes specify cam and turret assembly, output, input, and mounting positions, with options for right or left-hand cams and various motion curves.

Technical Parameters:
Allowable loads and torque on input and output shafts are specified, along with indexing accuracy and weight considerations.

Data Interpretation:
Tables and charts provide critical data on torque and load capacities, essential for ensuring mechanical components operate within safe and efficient parameters. Adhering to specified values is emphasized to maintain system integrity and performance.

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...

Overview Indexing Drives/Oscillating Drives/Roller Drives Indexing Drives • The indexing drives operate intermittently as follows: Dwell→AE Index→AE Dwell→AE Index. • Dwell: Output shaft stops rotating and cam follower touches the straight part of taper rib of roller gear cam. • Index: Output shaft rotates and cam follower touches the curve part of taper rib of roller gear cam. • Usually, the indexing drives dwells for a moment after input shaft rotates once and then output shaft indexes once. • After output shaft rotates, the indexing drives dwell. At this moment, the operators can decide the...
