torque coupling system for graphite impeller shafts - the

Why Does the Pump Shaft Keep Breaking?

Shafts with higher corrosion resistance are a good choice in these environments. Variable Speed: Torque and speed are inversely proportional. As the pump slows down, the shaft torque increases. For example, a 100-horsepower (hp) pump at 875 rpm requires

Modeling Torque Converter Characteristics in Automatic Drivelines

The torque converter plays an important role in transmitting the engine's torque during the multiplication (converter) and coupling (lock-up) modes. The torque multiplication mode happens in lower gear ratios to help the vehicle to accelerate, and then by speeding

METHOD OF CONNECTING AN IMPELLER TO A SHAFT,

The coupling 6 allows transmission of torque between the shaft 3 and the impeller 2; the coupling 7 allows transmission of torque between the shaft 3 and the impeller 1; the coupling 8 allows transmission of axial load between the tie rod 4 and the impeller 2.

Construction, Working, Operation and Maintenance of Fluid Couplings

3 Construction, Working, Operation and Maintenance of Fluid Couplings Pull-up Torque The pull-up torque of a motor is the minimum torque developed by the motor when accelerating from rest to the breakdown torque point.

Rigid Coupling: Rigid Shaft Couplings

This is important when the rigid coupling is used in a precision servo system as honing allows for greater surface contact with the shaft and higher torque transmission capabilities. Ruland manufactures one-piece rigid couplings in 1215 lead-free steel with a proprietary black oxide finish, 303 stainless steel, and lightweight 2024 aluminum.

The coupling 6 allows transmission of torque between the shaft 3 and the impeller 2; the coupling 7 allows transmission of torque between the shaft 3 and the impeller 1; the coupling 8 allows transmission of axial load between the tie rod 4 and the impeller 2.

Coupling

A coupling is a mechanical device which is used to hold two rotating shafts together. It is a permanent joint, unlike clutch which can be disengaged on the will of operator. With the help of couplings, we can join two shafts which are intersecting, colinear or parallel (with a small distance).

Drive system for impeller shafts

A drive system for impeller shafts includes a coupling that has a universal joint that is lubricated under all operating conditions. A housing is connected to the universal joint, which housing includes a hollow end portion adapted to receive the non-threaded end of an impeller shaft.

Types of Shaft Couplings

2021/5/4The beam coupling consists of single or multiple helical cuts in the coupling body which typically can accommodate parallel misalignments up to 0.025 inch and angular misalignments up to 7 degrees. They are used primarily for motion control applications where torques are typically below 100 inch-lbs. Zero backlash designs available ensure positioning accuracy between driving and driven shafts.

Shaft couplings

2006/1/1This chapter provides an overview of shaft couplings that are useful for transferring torque between two in-line, or nearly in-line, rotating shafts. The magnitude of the torque in the shafts is equal, although slipping and disengagement can cause speed variations.

Fluid coupling

The torque transmitting capacity of any hydrodynamic coupling can be described by the expression () (), where is the mass density of the fluid, is the impeller speed, and is the impeller diameter. In the case of automotive applications, where loading can vary to considerable extremes, r ( n 2 ) ( d 5 ) {displaystyle r(n^{2})(d^{5})} is only an approximation.

Coupling Shaft

Coupling shafts are usually stepped so that larger diameter bearings can be used on the main body of the shaft. The slenderness ratio of the shaft is small ( L/D 4) which makes it stiff. The factor of safety of the shaft (approximately 4) is chosen to resist predominantly shear stress due to torsion but also the effect of shock loads when the shafts start or stop suddenly.
