Product catalog summary
Overview of Cam Indexing Table
This document provides a comprehensive guide on the Cam Indexing Table by Hansheng Automation, covering 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 Motion Curves
Various motion curves like discontinuous, double stationary symmetric, and asymmetric are outlined, selected based on velocity, acceleration, and jerk for smooth operation and longevity.
3. Order Code and Model Selection
Guidelines for selecting the appropriate model based on torque load calculations are provided to prevent overload and ensure efficient operation.
4. Grease and Maintenance
Regular maintenance, including lubrication changes after 500-1000 hours, is crucial. Mixing different lubricants is discouraged due to varying chemical compositions.
5. How to Keep Precision
Precision is maintained through proper axial alignment and eliminating backlash, with regular checks and adjustments to prevent wear.
6. Examples and Calculations
Examples of calculations for selecting motion curves and determining torque requirements assist in model selection and performance optimization.
7. Model Descriptions
Descriptions of various models like DS Shaft, DF Flange Shaft, and others, each with specific applications and features, are provided.
8. Assembly and Installation
Instructions for assembling and installing cam indexers include fixing methods and the importance of overload protection units.
9. Safety and Overload Protection
Installing torque limiters is emphasized as a safety measure to protect machinery from overload.
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 selection depends on speed, with Petro China #90 oil recommended. Avoid mixing lubricants and replace them after 500-1000 hours initially, then every 3000 hours.
Table Installation and Indexing Precision
Table size should be based on torque load, with high precision requiring 2-3 times the torque. Hansheng indexer precision is ±30” for general grade and ±15” for precision grade.
Use Examples and Calculations
Example calculations for sub-table and conveyor applications include index stops, cam curves, and torque calculations, considering inertia, friction, and working torque.
Ordering and Model Specifications
Model codes specify cam and turret assembly, with options for right or left-hand cams and various motion curves. Technical parameters include allowable loads and indexing accuracy.

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...

To Maintain the Accuracy Factor■ The Size of Table To install a table on the output shaft, the size of table shall be based on the permitted output torque load for the Torque Te. While high precision is required, the Torque Te shall be 2-3 times larger than the permitted output torque load; therefore, the twist of the output shaft needs to be reduced. The table’s maximum diameter shall be 5 times less than the nominal dimension. Table 6. Maximum Diameter(mm) for the General Tables Hansheng indexer precision is dedicated by angle and guaranteed to be ±30” for general grade and ±15” for precision...
