Service Rotation Most people who have played any volleyball have been introduced to the idea of service rotation. There are six positions on the court (3 front row and 3 back row) and one of the positions is the designated server. Players rotate through each of these positions, serving when they rotate to the designated position. 1 4 3 2 5 6 Here you can see the court split into 6 equal parts ...

· Fig. 1(a) shows a ball–screw transmission mechanism with links 1, 2, 3, and 4 forming a crank–slider mechanism and links 4, 5, and 1 forming a ball–screw input is from the crank rotation while the output is the reciproing angle of the screw. The ball–screw transmission mechanism can be studied by analyzing the crank–slider mechanism and the screw linkage .
Ratchets are mechanisms that serve to limit either rotary or linear motion to only one direction. Ratchet designs vary but the basic composition of parts is fairly universal. A ratchet is composed of three main parts: a round gear, a pawl, and a base. There may be additional and distinct parts that make up a particular ratchet device. A force is often applied to the pawl in order to maintain ...
Two rigid bodies connected by this constraint will be able to rotate relatively around x, y and z axes, but there will be no relative translation along any of these axes. Therefore, a spherical pair removes three degrees of freedom in spatial mechanism. DOF = 3. Figure 46 A planar pair (Epair) A plane pair keeps the surfaces of two rigid bodies together. To visualize this, imagine a book ...

In planar mechanisms there are only two kinds of lower pairs: turning pairs and prismatic pairs. Functions of Linkages. The function of a link mechanism is to produce rotating, oscillating, or reciproing motion from the rotation of a crank or vice versa (Ham et al. 58). Stated more specifically linkages may be used to convert:
In lacrosse, a ball is thrown from a net on the end of a stick by rotating the stick and forearm about the elbow. If the angular velocity of the ball about the elbow joint is rad/s and the ball is m from the elbow joint, what is the velocity of the ball? A truck with tires travels at m/s. What is the angular velocity of the rotating tires in radians per second ...
· This mechanism realizes stable motions, because the rotation directions of ball wheels agree with moving directions of vehicle. Moreover, the step overcoming ability of ball wheels are higher than omniwheels. The ball wheel drive mechanism can be used under various circumstances. In this paper, we propose a ball wheel drive mechanism and evaluated its motion properties. Published in: .
A linear movement/rotation mechanism 100 includes a reduction gear 102 that reduces an output rotation of a motor 101, and a belt/pulley transmission mechanism 120 for transmitting a reduced rotation output to a ball screw/ball spline mechanism 110. The ball screw/ball spline mechanism 110 includes a drive shaft 113 in whose outer circumferential surface a ball screw thread 111 and ball .

These mechanisms also change the axis of rotation by 90 degrees, but in a different manner than bevel gears. Unlike other gears where the teeth are cut parallel, worm gear teeth are cut almost perpendicular to the shaft's axis of rotation while mating with a more traditional gear profile. Rack Pinion Gears . Rack Pinion Gears: Rack and pinion gears are used to convert rotation into ...
A ball point pen is a pen that uses a small rotating ball made of brass, steel, or tungsten carbide to disperse ink as you write. All of the pens that preceded the ballpoint whether quill, metal or fountain used a watery, dark india ink that fed through the pen using capillary action. The problems with this technology include: The ink can flow unevenly. The ink is slow to dry. The ink is ...
Turret Turning Mechanism By Geoff Dixon. Click on image to expand. For many years I have been building model battleships. One of the problems I have encountered is how to realistically turn the turrets. Over the years I have built many gearboxes to do this, some of which worked okay, others could be heard grinding slowly from the other side of the pond. Collectively I have a large box of ...
Rotary mechanisms can be used in interesting ways. The greetings card on the left allows the user to rotate a circular card disk. This changes the eyes on the front of the card. A brass split pin holds the disk to the card front but allows it be rotate. AS THE CARD ROTATES DIFFERENT EYES APPEAR MOUTH MECHANISM : The simple folding technique is ideal for forming a mechanism that unfolds when a ...
· An automatic dynamic balancer 1 (ADB), is a passively controlled device which requires no external forces to eliminate the imbalance of rotating mechanisms. An ADB works using two or more weighted balls housed in a race which is filled with a viscous fluid. As the rotor spins the forces on the balls cause them to move so as to eliminate the ...
In a linear movement/rotation mechanism (1), inside a tubelike housing (2), a ball screw/ball spline mechanism (3) and a hollow planetary reduction gear (4) are coaxially disposed, a drive shaft extends therethrough, and a ball screw nut, a ball spline nut (8), a hollow planetary reduction gear (4), and a driven pulley (5) are disposed in that order along a center axis of the drive shaft (6).
