A ball groove system is required when linear and rotary
movements are required. Previously, it was impossible to perform both movements.
However, the ball groove system provided lightness. This system has less
friction and less tendency to stick together. This way you get high efficiency
with less effort.
Ball groove system
Ball grooves are now used in many typical motion
applications due to the fact that they provide frictionless motion. It consists
of a groove (inner ring), an outer ring, and a coupling linear bearing. The
inner ring is made of alloy steel, induction heat-treated to 56-60 Rc (hardness
C according to Rockwell). In addition, some other splines have a Gothic arc
ball groove cross-section, which increases their service life.
Moreover, it
also offers smooth operation and low rotation speed. Then there is the outer
ring, which consists of 58-60 Rc hardened steel bearings. In addition,
recirculating bearing balls are available to reduce frictional wear. This way,
you can make an unlimited number of trips with minimal maintenance. In addition
to this, the outer track also has several active circuits, usually 3 to 6.
Thus, with the use of a ball groove system, you can easily move during
operation. So if you are looking for a ball slot, visit tuli-shop.com. You will

Corrugated ball applications
The splined spline is widely used in all industrial
operations. But this is not the end of it. They are also used in;
Honing machines
Doctor
Robotics
Automation and packaging equipment
Exploration for oil and gas
Water research
Internal and external track modifications.
You may not see this, but you can change the inner and outer
races. Therefore, if you have any special requirements, you can ask for changes
according to your needs. It may have holes for set screws or keyways for the
outer rings. It can also have threaded or trunnion ends for inner rings. You
can handle all of them if you need them. Likewise, if you need extra smooth
motion, longer life, high tolerance accuracy, and precision ground ball
grooves, this is all you need. In addition, the hollow shafts reduce the weight
of the system but lose it a little. Hence, you will have a loss of stiffness.
Lifetime
Since you will get efficient movement, you will need a
longer lifespan and you will get it here. If you get it the right size, you
will get medium torque life. If you are using the highest torque, you will need
extra life depending on the stroke length. Therefore, it is very important to recompense
attention to the use. This will allow you to obtain the correct size ball
splines.
Critical speed
Before purchasing a spherical spline system, it is necessary
to check the critical shaft speed. It also depends on your use. The use of
medical equipment is different from the use of robotics and therefore the speed
of its operation varies. The movement in industrial use is different from the
movement in medical practice. The critical speed is the maximum speed at which
the ball splines will move effortlessly.
Increasing the travel speed beyond the critical speed will
cause natural harmonics and vibrations. You don't want that. In addition, this
critical speed depends on the lifting capacity, diameter, rotation speed, distance
between the brackets and the end fixture, or the type of bearing bracket used.
So, before you buy a system, you need to pay attention to these things and
purchase the right hardware.
Support systems are different due to different uses. So, you
get 4 main categories in the support system. These include;
With free end and fixed end.
Where both ends just tilt
A type in which one end is simply supported and the other is
fixed.
A type in which both ends are fixed
