What are Shaft Output Indexing Drives
Hansheng Automation's shaft output indexing drive focuses on "long shaft automation equipment" (such as automobile transmission shaft processing, medical testing equipment, and electronic assembly lines). Through the "shaft direct drive design", it simplifies the traditional complex transmission chain and eliminates the hidden dangers of coupling wear. Relying on the company's Kashifuji KPS30 gear shaping machine (ISO 5 gear accuracy) and CNC grinder (shaft cylindricality ≤ 0.002mm) manufacturing capabilities, it achieves ±30 arc second indexing accuracy and 500kgf axial load capacity, solving positioning deviation and efficiency bottlenecks in heavy-load scenarios.
Core advantages of products
1. Direct shaft connection design
Abandoning the complex structure of traditional coupling + reducer, the output shaft is directly connected to the workpiece, reducing 3 transmission links and reducing the system failure point by 60%. In the processing of automobile transmission shafts, it can directly drive the φ80mm×1200mm long shaft to rotate, with ±30 arc second accuracy, to ensure that the drilling/milling position deviation is ≤0.01mm.
2. Heavy-load precision double balance
Load guarantee: The cast iron base achieves ±0.03mm form and position tolerance through lost foam casting, supporting a total load of 300kg (workpiece + tooling) without deformation;
Precision guarantee: Shaft parts are processed by CNC grinder (cylindricity ≤0.002mm), with low backlash gears (≤3 arc minutes) processed by Kashifuji gear shaping machine, and still maintain ±30 arc second accuracy at high frequency indexing (60 times/minute), which is suitable for the "high speed + precision" requirements of medical testing equipment.
3. Manufacturing process strength: full chain control from gears to shafts
Gear processing: Kashifuji KPS30 gear shaping machine achieves ISO 5 level precision, module 0.5-3.0 gear meshing is smoother, and life is increased by 40%;
Shaft finishing: CNC grinder achieves ±0.005mm dimensional accuracy, surface roughness Ra≤0.8μm, reducing rotational friction loss;
Casting process: sand casting/lost foam casting dual process to meet the cost and precision requirements of different batches (free tolerance ±1mm, specified tolerance ±0.03mm).

FAQ
Q: What is the core difference between shaft output indexing drive and flange type indexer?
A: The shaft output type adopts the design of "direct connection between output shaft and workpiece", which can directly drive the long shaft (such as the detection shaft of electronic assembly line, automobile transmission shaft) to rotate, eliminating the coupling and reducing the transmission error by 60%; the flange type is more suitable for turntable equipment (such as medical packaging turntable). If your equipment is "long shaft rotation positioning" (such as shaft drilling/milling groove), choose shaft output; if it is "turntable multi-station positioning", choose flange type.
Q: How to ensure the long-term stability of the indexing accuracy of ±30 arc seconds?
A: There are mainly three aspects:
Lubrication maintenance: add special lubricant every 500 hours to maintain the low friction state of gears;
Clearance inspection: check the gear meshing clearance every quarter (should be ≤0.02mm), and re-debugging is required if the tolerance is exceeded;
Load control: avoid exceeding 220kgf axial load (safety factor = 2, overload may cause deformation of cast iron base and affect accuracy).
Q: Can the shaft length be customized for special long shaft applications (such as extra-long drive shafts)?
A: Yes! We support customization of shaft lengths from 200mm to 1500mm, relying on CNC grinders (±0.005mm accuracy) processing to meet the "extra-long + high-precision" requirements of automotive drive shafts and medical testing long shafts. You can provide equipment drawings, and our engineering team can design an adaptation plan on a 1:1 basis.
Q: What maintenance should be paid attention to for high-frequency operation (such as 60 times/minute)?
A: Mainly focus on the two aspects of "heat dissipation + wear protection":
Heat dissipation: Clean the heat dissipation holes every month to prevent the equipment (net weight 32kg, lightweight design) from overheating due to dust accumulation;
Seal: Check the radial seal ring every quarter, and replace it in time if it leaks oil to prevent dust intrusion;
Wear detection: After running 10,000 times, check the wear of the cam roller (it is recommended to replace the original roller to maintain ±30 arc seconds accuracy).
