Dimensions of Sprocket

Sprockets is usually classified into regular sprockets, HK sprockets as well as other sprockets.
1. Regular sprocket
Common sprockets are ANSI sprockets which could be engaged with typical series roller chains. See P125 for dimensions.
You’ll find two types of tooth profiles: U-tooth and S-tooth.
2. HK sprocket
HK sprockets might be engaged with HK series roller chains, and those for single strand chains are identical to regular sprockets. Nonetheless, sprockets for many strand chains are different from normal sprockets in sprocket tooth profile.
3. Other sprockets
Other sprockets are built according on the following calculation formulas to suit respective specialty chains.
The sprockets applied for your following chains will be the exact same as the standard sprockets in tooth gap type, but different in tooth thickness (sprocket tooth profile).
4. Calculation of sprocket dimensions
The dimensions of regular sprockets and also other common sprockets are calculated as follows. At the outset, the diameters of sprockets are calculated in the following calculation formulas.
Upcoming, sprocket tooth profile (the form on the tooth determined by its thickness) is calculated from the following calculation formulas. (The values shown during the following pages had been calculated by these formulas and thought to be the regular values.)
Calculation formulas for diameters and tooth gap forms Calculation formulas for diameters
Calculation of pitch diameter, tip diameter and caliper diameter
The essential dimensions of the sprocket appropriate for any chain pitch of one mm are respectively called pitch diameter component, tip diameter element and caliper diameter issue. The respective variables for respective numbers of teeth are listed beneath. If these components are multiplied by chain pitch, the basic dimensions from the corresponding sprocket could be obtained.
Within the case of 80 (25.forty mm pitch) with 35 teeth Pitch diameter (Dp) = P×Pitch diameter element
Calculation formulas for tooth gap kinds
Because the most rational tooth gap varieties by which the pressure angle improvements in response for the elongation of the smoothly rotated roller chain together with the lapse of services time, ANSI specify two varieties of tooth profiles: U-type and S-type. Usually, S-type tooth profiles are adopted in accordance with ANSI, and our typical sprockets also have S-tooth profiles.
