We are Cardan Shaft Manufacturer in China. We have Cardan Shaft manufacturing experience over 20 years.

Cardan Shaft, Universal Coupling, universal joint shaft, transmission shaft or someone called Cross Shaft Universal Joints. They have a simple structure, high strength, good durability, high transmission efficiency, and low production cost. It is mainly composed of the active fork, driven fork, cross shaft, needle bearings, axial locating parts, and rubber seals, etc. It has a simple structure, high strength, good durability, high efficiency, and low production cost.

The following is an exploded view of the Cardan shaft

What is the producing process for Cardan Shafts?

Let's have a look at it.

After the drawing confirmed, the order received, the factory needs to prepare raw materials. Usually, we have a normal type in the warehouse, if a special one, we need to purchase outside.

All materials for Cardan shafts are ready, then start to produce.

- What will be the important production?

Yes, Forging, drilling, welding, installing, and painting. Let's start one by one.

1. First of all, the forging blank at both ends of the central hole drilling, rough outside a few big steps.

2. Conduct tempering.In this step we need external processing, quenching to remove the bad impurities inside the parts to make the Cardan shaft parts harder.

3. Semi-precision car steps, outer circle, and length of the spare, and then take the center frame car to the total length.

4. Drilling of through holes in the central Cardan shaft flange.

5. Enamel tapered holes at both ends, bore bored heads at both ends, and drill center holes to prepare for grinding.

6. Fine turning of each gear outer circle and step plane with grinding allowance, and chamfering of each groove on the outer circle.

7. Grinding all kinds of cylindrical and step planes to size

8, Measure all size by hands to avoid mistake when Cardan Shafts finished

9, All parts finished, start to install and welding

 

10, Balance Test, all cardan shafts we test before painting

11, After Cardan shafts balance test, waiting for painting

 

12, Finished paint, After the painting is finished, wait for it to dry before packing

 

13, Packing and shipping, normal packing or pack with woodencase, depends on  customers' requirement

Choosing the right Cardan shaft is crucial for ensuring the optimal performance and reliability of your machinery. At MND Auto Industries, we understand the importance of selecting a shaft that meets your specific requirements. Here are the critical factors to consider when buying a Cardan shaft:

 

Usually what happens is you have to have these details with you for your required Shaft and accordingly the manufacturer (MND AUTO INDUSTRIES) will make it for you.

1. Flange

The flange is the connecting interface of the Cardan shaft to the machinery. It must match the counterpart component precisely. Ensure the flange type and dimensions align with your equipment specifications to prevent misalignment and ensure a secure fit.

 

2. PCD (Pitch Circle Diameter)

The Pitch Circle Diameter is the diameter of the circle that passes through the center of all the bolts on the flange. Accurate measurement of the PCD is essential for compatibility with your equipment. Incorrect PCD can lead to improper fitment and operational inefficiency.

Jundi are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.

 

3. Bolt Size and Number of Holes

The bolt size and the number of holes on the flange are crucial for securing the Cardan shaft to the machinery. Ensure that both match your equipment's requirements. A mismatch can cause connection instability and potential mechanical failure.

 

4. Flange Thickness

The thickness of the flange affects the overall strength and durability of the connection. It is important to select a flange with an appropriate thickness to handle the operational loads without deformation.

 

5. Keyway Depth

The keyway depth is essential for ensuring a secure and stable connection between the shaft and the hub. An incorrect keyway depth can lead to slippage or misalignment, causing operational issues and potential damage.

 

6. Flange Face to Face Length

The face-to-face length of the flange determines the overall length of the Cardan shaft. This measurement is critical for ensuring that the shaft fits properly within the available space in your machinery and operates smoothly without causing stress to other components.

 

7. UJ Cross Bearing Cup

The Universal Joint (UJ) cross bearing cup size is a key factor in the flexibility and range of motion of the Cardan shaft. Ensure the bearing cup size is compatible with your application to facilitate smooth rotation and reduce wear and tear.

 

8. Closed Length and Expanded Length

The closed length and expanded length of the Cardan shaft determine its range of compression and extension. These dimensions are crucial for applications where the shaft needs to adjust to varying distances during operation. Ensure these lengths match your requirements to avoid overextension or compression.

 

9. Male Spline Shaft

The male spline shaft must match the corresponding female component in your machinery. The spline ensures torque transmission without slippage. Verify the spline dimensions and count for compatibility.

 

10. Pipe Diameter

The diameter of the pipe affects the strength and torque capacity of the Cardan shaft. Select a diameter that can handle the operational torque without bending or breaking. This is particularly important for high-torque applications.

 

11. Torque

The torque capacity of the Cardan shaft must be sufficient to handle the operational loads of your machinery. Ensure the shaft is rated for the maximum torque your application will generate to prevent mechanical failure.
