Dimensions of Sprocket

Sprockets might be classified into typical sprockets, HK sprockets and also other sprockets.
1. Standard sprocket
Standard sprockets are ANSI sprockets which can be engaged with regular series roller chains. See P125 for dimensions.
There are actually 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 standard sprockets. Nevertheless, sprockets for multiple strand chains are various from standard sprockets in sprocket tooth profile.
3. Other sprockets
Other sprockets are designed in accordance on the following calculation formulas to suit respective specialty chains.
The sprockets utilized for the following chains would be the exact same as the normal sprockets in tooth gap type, but various in tooth thickness (sprocket tooth profile).
4. Calculation of sprocket dimensions
The dimensions of conventional sprockets and various common sprockets are calculated as follows. To start with, the diameters of sprockets are calculated through the following calculation formulas.
Up coming, sprocket tooth profile (the form in the tooth based upon its thickness) is calculated from the following calculation formulas. (The values shown within the following pages were calculated by these formulas and regarded as the normal values.)
Calculation formulas for diameters and tooth gap types Calculation formulas for diameters
Calculation of pitch diameter, tip diameter and caliper diameter
The essential dimensions of a sprocket ideal for any chain pitch of one mm are respectively termed pitch diameter aspect, tip diameter aspect and caliper diameter issue. The respective components for respective numbers of teeth are listed under. If these aspects are multiplied by chain pitch, the essential dimensions on the corresponding sprocket is usually obtained.
While in the situation of 80 (25.40 mm pitch) with 35 teeth Pitch diameter (Dp) = P×Pitch diameter component
Calculation formulas for tooth gap kinds
Because the most rational tooth gap types by which the stress angle modifications in response to the elongation of a smoothly rotated roller chain together with the lapse of services time, ANSI specify two types of tooth profiles: U-type and S-type. Generally, S-type tooth profiles are adopted in accordance with ANSI, and our normal sprockets also have S-tooth profiles.
