New Modules Updated Modules. Included in this section are drum brakes. View other versions 5. Introduction Where power has to be transmitted between two shafts which are a distance apart, a belt or rope drive is frequently used. Power is the rate at which work is done or energy is transferred in relation to time.
In calculus terms, power is the derivative of work with respect to time. An engine or motor is a machine designed to convert energy into useful mechanical motion. Flat Pulley Drives. Although described as Flat , many pulleys used with flat belts are actually slightly curved so that the diameter at the middle is slightly larger than that at the ends.
Resolving Tangentially Allowance For Centrifugal Force. Centrifugal force represents the effects of inertia that arise in connection with rotation and which are experienced as an outward force away from the center of rotation.
The analysis above assumes, in effect, that the belt and pulley is at rest. In practice this is not often the case when the belt is subjected to a centrifugal force as if passes round the pulley.
If is the weight of a unit length of belt and is the linear belt speed, then the force on an element. Grooved Pulley Drives Although rope can be used for such drives, the vast majority rely on V-belts.
Assuming that the included angle of the groove is , the Normal Reaction is given by,. The Power Transmitted Two sets of equations are given below to cater for both measurement systems:. Imperial The horse-power transmitted 8.
It is usual to assume that the mean tension is constant at all speeds, and is therefore equal to the initial tension. If is neglected it then follows from equation 4 that: And hence the power transmitted at a given speed is proportional to the initial tension. A band brake is a brake in which the frictional force is applied by increasing the tension in a flexible band to tighten it around the drum.
The principles of Band Brakes are similar to those of the preceding paragraphs, giving in this case the braking torque which can be applied to a rotating drum.

Model RS drives offer backlash-free linear motion even during reversal. The drive nut runs on a smooth shaft with no threads to clog or jam. Fast acting clamping systems for rolls, spools and other static or driven shaft applications.
Easy to use and install, clamps are available in two different styles to meet application requirements. Model ARG and ARS drive assemblies are furnished ready for machine-mounting including drive unit, shaft, rails, end stops, and a variety of other options.
In a rolling ring drive the inner race of the bearing is specially machined. The bearings are then mounted in a housing which is placed on a smooth, threadless shaft. The bearings may be pivoted left or right on the shaft. When the rolling rings are angled on the shaft, and the shaft is rotated, compression is generated against the machined inner race causing the bearings to roll along the length of the shaft.
The rotary input motion provided by the motor-driven shaft is thereby converted to linear output. The angle of the rolling rings relative to the shaft determines travel direction and linear pitch distance traveled per shaft revolution.
Production machinery designed to provide reciprocating motion requires an integrated linear drive assembly to move the tool head back and forth. Reciprocating motion applications include: Painting, grinding, slitting, scanning, winding, scoring, spraying — basically any task where back-and-forth motion Understanding Rolling Ring Linear Drives. Rolling ring linear drives are used worldwide, to meet a variety of positioning and reciprocating linear motion applications.

WO// WIRE ROPE DRIVE MECHANISM FOR RECIPROCATING LINEAR MOTION
A rope drive is a form of belt drive , used for mechanical power transmission. Rope drives use a number of circular section ropes , rather than a single flat or vee belt. These multiple rope drives replaced the earlier technique of a vertical wrought iron shaft with bevel gears at each floor. They remained in use for as long as mills were driven by central steam engines, rather than individual electric motors. A installation at Droylesden split the output of one motor between two floors with two new rope drives.
Shaft drives had often used gearing from the engines to increase their speed, and thus their power transmission. This was avoided for rope drives, as the rope's maximum useful speed could be achieved from the engine's flywheel and flexibility of the ropes led to backlash in the gearing. US practice sometimes used a single rope, looped between floors and tensioned by an idler pulley, but this system was not used in the UK and each loop was tensioned between its two pulleys by one of them being movable.
Rope drives were also cheaper than belts - around a quarter of the price. The rope drives were placed in a large diagonal shaft at the side of the building, usually windowless and distinctively visible from outside the building.
Rope drives required a larger such shaft than comparable belt or shaft drives. As the open shaft represented a channel for transmitting fires, unlike the narrow holes of a shaft drive, it needed careful fireproofing from the loom floors. It was sometimes arranged for large drives that the engine drove a set of horizontal ropes to a pulley on a layshaft or 'second motion shaft' alongside the engine house, then diagonally up through the shaft.
