How Does A Sprag Clutch Work? | GMN Bearing USA

The Design & Functionality of a Sprag Clutch. Sprag clutches are designed to transfer torque in one relative direction, referred to as the "engaged direction," and to disengage—or "freewheel"—in the other direction. That means in the engaged direction, there is no relative rotation allowed between the two components connected by the ...

102B-Series Sprockets

102B-Series Sprockets. 102B series engineer class sprockets are used for a wide verity of chain sizes. For cast sprockets, these sizes include A102B, S102B, C102B conveyor chain, SS102B, 6102B, ER102B, and SBS102B. These sprockets are typically supplied as cast material but we can also supply them as steel for longer operation.

drag conveyor brochure conveyor and material handling

The difference is in the conveying efficiency. Drag chain conveyors use nearly 50% of the available space inside the conveyor housing for material movement, while en-masse drag chain conveyors use up to 90%. By comparison, belt conveyors only use about 20% and screw conveyors only use about 45%.

What Is Sprocket?- Definition, Types, and Terminology

A sprocket, sprocket-wheel, or chain wheel is a profiled wheel with teeth that mesh with a chain, bar, or other perforated or notched material. The name "sprocket" applies generally to any wheel on which radial projections engage in a chain running over it. It differs from a gear in that sprockets never mesh directly with one another, and ...

Belt Conveyor for Bulk Materials

All conveyors require an additional belt tension in order to allow the pulley to drive forward an effective tension without slipping. In a case of a simple horizontal conveyor T1 is the sum of the effective tension Te and the slack side, the tension T2. T 1 = T e + T 2 = For the inclined conveyor, additional tensions are induced due

Sprocket Engineering Data

American sprocket manufacturers have adopted 4 specific types of sprocket construction styles as American Standards . In addition to the standard sprockets, special sprockets may be available in the same styles . Style A - Flat sprocket with no hub extension either side . Style B - Sprocket with hub extension one side .

Types of Sprockets

Type B sprockets, which have a hub on one side. Type C sprockets, which have hubs of equal thickness on both sides of the plate. Type C offset or Type D sprockets, which also have two hubs. However, each hub has a different thickness, making the sprocket asymmetrical. The different types allow for different applications.
