Cranks mechanism

This paper introduces a new press structure that utilizes a double crank mechanism to enhance productivity and efficiency for the stamping process. By adjusting the positions between the component links, the dynamic characteristic of the ram can be modified, optimizing the performance and improving operations of the system.

The sausage feeder takes an important role in automatic packaging systems. This paper presents the theoretical calculation, kinematic characteristics of an automatic sausage feeder using vibration technique and crank mechanism. The kinematics formulation of the crank mechanism is done using vector loop method and cosine rule are applied to describe the position of the mechanisms. Velocity of crank and connecting rod is performed by differentiating the position in terms of following crank angle and connecting rod angle respectively.

The investigation analyzes effects of clearance size in revolute and spherical joints with clearance on rigid-flexible dynamic of a space slider crank mechanism by finite element method. The model of the mechanism was designed by Solidworks and then velocity, acceleration, displacement, stress and contact force were determined by finite element analysis of rigid-transient dynamic in ANSYS.

In this paper, the measurement of the mechanical parameters like force requirement, hand cranking capabilities, length of cutting & moisture content of different fodders are reported. Force requirement was increased gradually due to the presence of high moisture content of fodders and large size diameter of fodders. Hand cranking capabilities at load conditions gradually decreased compare to at no-load conditions.

The torsional vibration phenomenon in the running gear of reciprocating engine systems is usually dealt with by considering a series of constant inertias connected by sections of massless shafting. However in reality, a slider crank mechanism is a vibrating system with varying inertia because the effective inertia of the total oscillating mass of each crank assembly varies twice per revolution of the crankshaft.

Transplanting is the major method of rice cultivation in India. Irrespective of the method of paddy crop establishment, weed is a major impediment to rice production through its ability to compete for resources and their impact on paddy crop yields. The cutting tool will make a reciprocation maximum motion of 6 cm perpendicular to the direction of transplanted crop rows. This gives an effective working width of 16 cm leaving 7 cm as root protective zone on either side of the weeded rows.

The compensating crank is an adjustable lever in the feedback linkage between the servomotor and the large plunger of the dashpot. Adjusting the compensating crank adjusts the amount the large dashpot plunger moves for a given movement of the servomotor. If there is no leakage in the oil reservoir, the small dashpot plunger will move rigidly with the large plunger and there will be additional permanent speed droop.

Move gates to 10 percent open as measured at the scale on the servomotors and check to see if the gate position needle indicates 10 percent. If the gate position needle does not indicate 10 percent, move the eccentric adjustment in the restoring shaft bell crank to position it correctly (photograph 3). Move it toward the restoring shaft if there is over travel and away from the restoring shaft if there is under travel (figure 7). Move the gates to 90 percent, as measured at the servomotor scale, and check the gate position indicator needle. It may...

Place a small level on top of the compensating crank (photograph 1). Make sure that it is resting on a flat portion of the crank. If the compensating crank is not level, adjust the length of the restoring cable to make it level. After each adjustment, operate the gates back and forth several times to seat the restoring cable and then bring the gates back to exactly 50 percent. When the compensating crank is level with the gates at 50 percent, the black gate position needle should be at 50 percent. If it isn’t,...

In this day and age of ever-shorter time schedules and increasing expectations of productivity gains in every aspect of engineering activity, creative problem solving has become prominent among the most important skills that engineers possess. Unfortunately, in the day-to-day intensity of the search for new engineering solutions, it is easy to lose touch with the foundations of that creativity.

In the fourth chapter of this section, the authors present a modification of the Crank- Nicholson scheme for two-dimensional fluid mechanical, heat and mass transfer problems. The modification divides the nodal points into groups of four. The method is applicable to parallel computing, which is increasing in importance as problems become more computationally intensive. Computational experiments demonstrate improved convergence rates over previous methods.

CHAPTER 13 KEY EQUATIONS AND CHARTS FOR DESIGNING MECHANISMS FOUR-BAR LINKAGES AND TYPICAL INDUSTRIAL APPLICATIONS All mechanisms can be broken down into equivalent four-bar linkages. They can be considered to be the basic mechanism and are useful in many mechanical operations. FOUR-BAR LINKAGES—Two cranks, a connecting rod and a line between the fixed centers of the cranks make up the basic four-bar linkage. Cranks can rotate if A is smaller than B or C or D. Link motion can be predicted.
