[Technical Protection Point] 1. A sprocket drive mechanism with adjustable speed ratio, comprising an active sprocket (1) and a driven sprocket (2); said driven sprocket (2) is coaxially connected with a metering roller; characterized in that: it also includes a transition sprocket (3); said transition sprocket (3) is a double sprocket structure, which includes a coaxially set...
Hollow pin chains are designed with double curved arcs to reduce friction, and they are used in places where the power is high but the running speed is slow, and they have obvious advantages over belt drives, such as pneumatic compressors. Hollow pin chains are used for conveying, single pitch, double pitch and long pitch are available. Attachment or crossbar can be inserted...
Chain wheel is one of the common parts, due to different applications, its tooth size, tooth number, etc. vary, but its tooth shape and pitch are standard, the most common tooth shape is "three arcs a line" standard tooth shape, the tooth shape of each parameter in the design manual can be found. Figure 1 shows the standard "three arcs and one line" chain wheel tooth shape...
Modeling a chain drive system Modeling the dynamics of a sprocket assembly, i.e. a chain drive system, is usually a difficult task for various reasons. In order to simulate a sprocket drive system, all relevant components in the chain drive must be modeled. However, since a typical chain drive consists of multiple chain links that are interconnected...
Sprocket parameters In order for the chain rotation system to work properly, sprockets and chains should be compatible with each other. To ensure this, the distance between the centers of adjacent teeth of the sprocket wheel should be aligned with the pitch of the chain. Similarly, each sprocket tooth should be constructed so that it fits the sprocket. And the maximum width of the sprocket should be less than the width of the internal link plate...
The number of teeth of large sprocket = the number of teeth of small sprocket X speed ratio After determining the number of teeth of small sprocket, multiply by the speed ratio, then the number of teeth of large sprocket can be determined. Generally speaking, the number of teeth of small sprocket is 17 teeth or more, 21 teeth at high speed, 12 teeth at low speed, but the number of teeth of large sprocket should not exceed 120...
Spur Gears The most common gears are straight cylindrical gears, which are used for large gear reductions. The teeth on spur gears are straight and mounted parallel to each other on separate shafts. Spur gears are used in washing machines, screwdrivers, wind-up alarm clocks, and other devices. Because gears mesh and collide, each impact produces a loud noise...
All bevel gears have much in common in their design and manufacture, but those destined for use in shredders must have certain key characteristics that are not part of the industry standard since automotive. This phenomenon is often observed in the large bevel gear industry today, and these critical characteristics are not widely understood in the engineering community, let alone...
TSH technology is an advanced induction hardening process specifically designed to reduce overall costs and replace chemical heat treatment processes. Traditional heat treatment of sprocket gears consists of a long gas carburization in an intermittent or continuous furnace followed by an oil quench. Typically, the gears are tempered in a low-temperature furnace for one hour. After carburizing,...
1、The sprocket should be installed on the shaft without skew and swing. The end surfaces of two sprockets in the same transmission assembly should be in the same plane, and the deviation of 1mm is allowed when the sprocket center distance is below 0.5m; the deviation of 2mm is allowed when the sprocket center distance is above 0.5m. However, it is not allowed to have the phenomenon of rubbing the side of sprocket teeth...
