Introduction to drive shafts
Functions
A drive shaft is a device to smoothly transmit rotation torque by connecting a driving shaft and a driven shaft that are not aligned on the same axis.
Since it has two universal joints on one shaft, it can connect the driving
shaft and the driven shaft flexibly.
In addition, one universal joint has four rolling bearings (cross & bearing)that can minimize torque loss with low friction.

2. Spline seal structure of muddy water resistance improvement
Features
Since the cover tube type spline seal has a structure that seals the sleeve (female spline) outer diameter part,(1) It is not necessary to surpass the male spline major diameter by deforming the seal lip at the time of assembly,
so a urethane rubber seal with high rigidity can be used.
(2) The distance from the seal to the spline is long, so muddy water does not reach the spline easily.
(3) A double cover has been added to protect the seal part, improving endurance further.

Handling explanation
High wing series features safe and secure torque transmission by a parallel key, andhigh torque capacity.
The following are the handling method and caution points to ensure that the drive shaft
delivers its expected performance.

Handling of drive shaft
Caution points for handling(1) Do not hit the cross & bearing part with hard metal so that a shock should be avoided.
If it is necessary at the time of assembling, hit it lightly with a non-ferrous metal(copper, etc.) or plastic hammer.
(2) Tighten the fixing bolts of the bearing cups by setting the bearing cups in theproper positions in the yoke to form an X shape.
If you fit the bearing cups with the tightening force of bolts or fix only one bearing
cup with the bolt and then set the other, it may cause troubles such as scars on
the spigot joint part and attaching surface, and attachment of bearing cups at aslant.
(3) Never conduct welding between the bolts and the bearing cups and between theyoke and the bearing cups.
(4) Do not disassemble the cross & bearings unless absolutely necessary.

About lubrication
Grease nipple(1) Greasing interval
It is recommended to apply grease every 2000 - 4000
hours, though it depends on the usage environment.
(2) Grease to be used
Lithium grease with extreme-pressure additive(3) Greasing of cross & bearings

Plug

Apply grease until it overflows from all of the four
shafts of the cross. Wipe off the overflowing grease
because dirt may adhere to it.

About cross & bearing attaching bolt(4) Greasing of spline partTo apply grease an onboard drive shaft, move thevehicle

body

so

that

the

splineshouldbecompressed to the minimum. When grease leaks outof the center of the plug attached to the sleeve yoke,greasing is complete.
If the drive shaft is removed from the vehicle becauseof overhaul, etc., apply grease with the splinecompressed to the minimum.

(1) Bolt
Use the attached bolt or part for repair specified by
JTEKT.
(2) Torque wrench
Use a calibrated torque wrench.
(3) Specified tightening torque
Tighten with the specified torque.

Universal joints are usually installed in pairs. When assembled as shown in Fig. 4, that is,(1) With equal operating angles in both joints(2) Yokes connected to the same shaft in line
(3) Central lines of all three shafts (driving shaft, intermediate
shaft, and driven shaft) in the same plane, the driven shaft
rotates exactly in the same way as the driving shaft.
Therefore, they should be attached as shown in the figure on
the right as far as possible.

Technical data 2
Drive shaft selection
A drive shaft should be selected so as to satisfy the required strength, service life, operating angle and dimensions necessitated by its purpose.
Especially, a drive shaft can be selected if it meets conditions of both strength and life of the universal joint, except for special cases.

Load torque of drive shaft

Strength of drive shaft

To decide the size of the drive shaft, it is necessary to grasp

A drive shaft should be selected so that the normal
maximum torque shall not exceed the “torque." However,
it is difficult to determine the true maximum torque, and theengine capacity or motor capacity is used as the maximum
torque in many cases, so the safety factor ( ) of no less than
1.0 should be considered as the most desirable.

the load torque first.
A maximum torque including an impact torque and a mean
torque should be known, and it is essential for selecting anappropriate drive shaft to understand the correct maximum
torque and mean torque.

=
Maximum torque:
Value to determine if the strength of each part is sufficient.
Mean torque:
Value necessary to calculate the service life

The maximum torque that may occur in an emergency should bedetermined using "torque." The safety factor ( ) of no lessthan 1.5 should be considered as desirable in this case as well.

Mean torque
It is apparent that all kinds of machines are not operating

Life of drive shaft

shaft is selected according to a service life calculated fromthan necessary.
So, it is reasonable to set up a longer expected service life, if
the application condition are severe; and shorter, if the conditions are easy.
If, for instance, a job is expressed as in the table below,
Drive stage
TorqueThere is no worldwide standard for service life calculation of universal joint bearings (cross & bearings) and the service life is calculated
according to the unique method developed by each manufacturer.
JTEKT employs the following empirical equation based on
extensive experimentation (conforming to SAE).
The service life
is defined as the expected number of operating
hours before a flaking occurs on the rolling contact surface of the
bearing. The use of the bearings over the service life
may bepractical on a low speed machine.

outlined in this catalog is a common rough guide. It is
recommended to consult JTEKT for details.

Balance quality of drive shaft
If a rotating drive shaft is unbalanced, it may adversely influence the equipment and ambient conditions, thus posing a problem.
JTEKT designs and manufactures drive shafts to satisfy the balance quality requirements specified in JIS B 0905.

Expression of balance quality

Balance quality grades

The balance quality is expressed by the following equation:

The JIS specifies the balance quality grades from G0.4 toBalance quality =G4000.

or

Generally, the three grades described in Table 1

below are commonly used.
Balance quality =

Especially in the case of a long drive shaft, this two planebalancing method is the only way to acquire good results.

Analysis/evaluation equipment

With improvement with FEM using a 3D model and review of the allowable differential angle based on
our achievement in the market over more than 40 years, JTEKT proposes optimal design and products
suitable for applications.
We also implement evaluation with actual products as necessary.
