Transportation and storage

In order to protect the staff and the universal joint from damage, it is necessary to ensure the safe transportation and storage of the universal joint.

Please read the following preventive measures in detail:

Use thick nylon rope and lifting belt, and pay attention to protecting both ends of the shaft when using steel rope.

The universal joint should be transported in a horizontal state (see instruction manual)

If this requirement cannot be met, after transportation

Appropriate protective measures should be taken during the process to prevent the spline from slipping off the shaft due to detachment,

Suitable crossbeams and brackets must be used for storage.

When storing universal shafts, it is necessary to place stoppers to prevent the shaft from rolling.

When storing the universal joint vertically, make sure it cannot fall down

The universal joint must be stored in a dry place.

When lifting the universal joint, the tilting of the movable parts (flange fork and cross shaft) can cause danger and injury.

Remember not to touch the universal joint with your hands, as there is a serious risk of injury!

During transportation and storage, avoid vibration and impact.

When storing and installing the universal joint, no external force should be applied, and no load should be placed on the spray coating and sealing ring of the spline.

In order to ensure consistency between the performance of the universal joint and the manual introduction, the performance status of the delivered universal joint cannot be changed arbitrarily

In places where personal and material hazards may be caused by rotating universal joints, safety protection measures must be taken.

Suitable safety protection devices (such as brakes, fixed safety covers) must be equipped to prevent the universal joint from loosening and slipping during rotation.

Extremely dangerous!

The universal joint has the characteristics of elasticity and flexibility, and the strength of its flexible vibration and critical bending velocity must be carefully calculated. Its maximum allowable velocity must be completely lower than the critical bending velocity provided at the time of initial order.

To ensure the safe and smooth rotation of the universal joint, it is prohibited to exceed the corresponding universal joint size nx? If there is any error in the range of values (velocity x inclination angle), please consult us.

To ensure the safe connection of the universal joint, it is necessary to keep the surface of the flange of the universal joint and the flange of the connected part free of dust, oil stains, and paint.

When installing the universal joint, remember not to move the flange and head arbitrarily to avoid injury.

Check the position of the flange fork of the universal joint, pay attention to its arrow mark, and calibrate it carefully. It is forbidden to replace or change the spline at will.

Before installation, remove the transportation protection materials (such as baffles, etc.). If you have any doubts, please contact us.

Check the axial and radial runout of the shaft, as well as the pins used to secure the flange and connecting components (refer to the flange section of the universal joint)

Do not use the installation lever to rotate the universal joint to avoid damaging the oil nozzle and pressure reducing valve.

Use bolts and screws of specified material (strength).

The required bolts and screws should be tightened symmetrically and evenly with a torque wrench.

When using a fixed length universal joint, one of the connecting components of the universal joint is connected to the locating pin of the flange by elasticity

Adjust the length compensation caused by temperature changes using appropriate bearing adjustment devices,

If a telescopic universal joint is used, the flange of the connected part must be firmly fixed on the universal joint.

If the storage period of the universal joint exceeds 6 months, it should be re lubricated before use,

When spraying the universal joint, be sure to confirm the sliding range of the sealing ring (length compensation La).
