How to estimate required torque for a partial rotation angle damper
Calculating based on the lifting force & length of application

Rotary dampers operate the applications gently.
The viscous resistance of the oil filled in the rotary damper provides the following advantages:- Control of sudden operation- Noise reduction- Impact mitigation- Safety enhancement

F

You can select rotary dampers from among the following three product groups according to your application:
Partial rotation angle damper for horizontal and vertical uses, and continuous rotation dampers.

Rotary damper
Horizontal use is applied tothe case where the final position ofa moving object (application)
becomes horizontal.

Vertical use is applied tothe case where the final position ofa moving object (application) issuspended vertically.

A rotary damper is placed at therotation center, and the rotary damper
torque increases gradually as
the position becomes horizontal.

A rotary damper is placed at therotation center, and the rotary damper
torque becomes the largest at thehorizontal position and thendecreases gradually.

■ Applications- Dust boxes- Toilet seat covers- Piano lids
- TV console doors- Industrial refrigerator doors

Torque adjustment function

Combining TD27/28 with an optional bracket enables the use ofthis product as a rotary damper hinge.
It can be attached easily, and the shape of the rotary damper hinge
can be changed depending on the method of mounting the bracket.
And the cap of the bracket is detachable and can be used for either side.
(It's best to minimize the number of times of detaching the cap)
Torque adjustment slot

Enlarged view

TD27/28 Bracket

Product nameTD27/28 Bracket

As the torque of the rotary damper is adjustable, it is not necessary to obtain the products withvarious torques according to the application to be used.
The torque can be adjusted simply by turning the slot of the rotary damper with a flathead screwdriver.
Since the torque adjustment range can be more than doubled, the same rotary damper is applicable toboth an application of 0.49 N･m and an application of 1.27 N･m.
Adjusting the torque makes coping with fine feeling and variation in an application possible.

Product information

Typical rotary dampers operate faster when the torque from the application
is higher than the preset torque and slower when the torque from the application
is lower than the preset torque. However, SR3 maintains a constant damping
speed through automatic torque adjustment.

Performance management testing method

Opening angle

As this product uses two rotary dampers, the damper performanceof each rotary damper is checked before assembling them into a hinge form.
As the torque of partial rotation angle dampers is not consistent, the closing
time measurement jig is used for the performance tests.

Warning

About rotary dampers

Precautions to prevent injury and accidents.
■ Improper use could lead to damage and breakage.
Carefully read the specifications and precautions for the rotary dampers and carry out the initial
performance verification, durability test, and environment test to sufficiently verify the quality and safety ofthe product to which the rotary damper is mounted.
■ Disassembly, modification, reworking, and repair of rotary dampers could cause an accident.
Disassembling, modifying, reworking, or repairing rotary dampers is prohibited.
A deterioration in performance or strength may lead to a malfunction or an accident.

Q: Please tell what “CW / CCW” means in terms of the direction.
A: The direction of rotation of the shaft in which torque is generated.
When looking from the shaft side with the housing fixed, torque is generated:- if the shaft is rotated clockwise – CW (R)- if the shaft is rotated counterclockwise – CCW (L)- in both directions – CW & CCW
Q: What kind of oil is used?
A: Silicone oil.

■ Do not use beyond the product specifications and ratings.
Using the rotary dampers outside the range of their product specifications could cause an accident.
■ Do not set on fire.
Setting fire to a rotary damper could cause a fire or an explosion.
■ Do not use rotary dampers as stopper.
Be sure to place a stopper to prevent the opening/closing angle of the rotary damper from exceeding
its allowable limit.

Q: Although the direction of rotation of the shaft of the rotary damper is shown in the catalog,
what will happen if the housing is rotated?
A: The direction of rotation in which torque is generated is the opposite.
If the shaft direction of rotation as described in the catalog is CW, rotating the housing
in the CCW direction generates torque. The torque characteristics are the sameas the ones that can be obtained when the shaft is rotated.
Q: Can partial-rotation-angle rotary dampers produce a damping effect from bidirectional rotation?
A: Yes, they can.
Q: Will the torque value be doubled if two rotary dampers are mounted to an application?
A: Yes, it will.

■ Do not use the rotary damper if it is found to be defective.
The performance of the rotary damper may be insufficient, leading to an accident.

Example: The torque of the lid: 2.0 N･m
Mount the rotary dampers onto both sides of the lid in a way
such that the shaft faces inward.
- TD99A1-10K (1.0 N･m in the CW direction)- TD99B1-10K (1.0 N･m in the CCW direction)

Caution

Q: I’d like to know about the places and methods of use for the products in detail.
A: The operations of the products are explained on our website in detail.
Please search for “TOK Applications” and refer to the Application page.

Describes the precautions for using the rotary dampers safely and correctly.
■ Secure sufficient strength of the peripheral component to which the rotary damper is mounted.
Consider the safety factor of the component to which the rotary damper is mounted, based on
the load torque, to prevent it from breaking.
■ Do not use outside the range of the operating temperature.
If the range of the operating temperature is exceeded, the part strength of the rotary damper varies,and sufficient performance cannot be achieved.
■ Do not apply a load exceeding the preset torque.
Any use under a load exceeding the specified torque described on the specification sheet of eachrotary damper or under an external force that operates the opening/closing angle of the rotary damper in
1.0 second or less could cause breakage.
■ Avoid attaching an organic solvent (such as thinner and ether) or using it in a corrosive atmosphere.
Organic solvents could melt or decrease the strength of the components of the rotary dampers.
■ Treat as industrial waste when disposing.
For environmental preservation, dispose of according to the law concerning waste treatment and cleaning.

FAQs

About torqueAbout purchase

Q: What is the torque management condition for the continuous-rotation rotary dampers describedin the catalog?
A: The basic measurement condition is 30 min-1 in a thermoneutral (23 ± 2°C) environment.

Q: Are you selling products online?
A: No, we are not. There are TOK branch offices in Japan, China, the USA, and Germany.
Please contact each TOK office to purchase our products.

Q: Why do the incoming products behave differently from the graph shown in the catalog?
A: The graph shows typical values, and its operation is not guaranteed.
All products shall comply with the product specifications specified by TOK.

Q: Please advise about the minimum order quantity (MOQ).
A: The MOQ is 10 pcs.
Q: Please advise about the payment conditions.
A: Payment is T. T. remittance in advance.

Q: Can rotary dampers, which are applicable to any other torque than as described in the catalog,
be fabricated?
A: It's on a case-by-case basis. Please contact us.
Q: Is it possible to fabricate rotary dampers whose torque values are odd, but not nice round values,
such as 5K, 10K, 15K, and 20K?
A: Although the torque values can be adjusted more or less, the unit price increases
because of customization.

Q: Is it possible to carry out a new test that is not carried out by TOK?
A: It is almost possible.
There may be an additional cost depending on the test conditions.
(Example: A case where the test cannot be carried out with existing equipment
or where it takes a long time to carry out the test)

About production
