Dimensions of Sprocket

Sprockets is usually classified into normal sprockets, HK sprockets and also other sprockets.
1. Conventional sprocket
Typical sprockets are ANSI sprockets which can be engaged with common series roller chains. See P125 for dimensions.
There are two styles of tooth profiles: U-tooth and S-tooth.
two. HK sprocket
HK sprockets can be engaged with HK series roller chains, and these for single strand chains are identical to typical sprockets. However, sprockets for various strand chains are different from common sprockets in sprocket tooth profile.
3. Other sprockets
Other sprockets are designed according on the following calculation formulas to suit respective specialty chains.
The sprockets used for the following chains are the same since the conventional sprockets in tooth gap kind, but distinctive in tooth thickness (sprocket tooth profile).
four. Calculation of sprocket dimensions
The dimensions of normal sprockets and also other basic sprockets are calculated as follows. Initially, the diameters of sprockets are calculated from your following calculation formulas.
Up coming, sprocket tooth profile (the form of your tooth based upon its thickness) is calculated through the following calculation formulas. (The values shown while in the following pages had been calculated by these formulas and regarded as the typical values.)
Calculation formulas for diameters and tooth gap varieties Calculation formulas for diameters
Calculation of pitch diameter, tip diameter and caliper diameter
The basic dimensions of the sprocket ideal for a chain pitch of 1 mm are respectively identified as pitch diameter component, tip diameter element and caliper diameter element. The respective things for respective numbers of teeth are listed below. If these aspects are multiplied by chain pitch, the essential dimensions from the corresponding sprocket is usually obtained.
From the case of 80 (25.forty mm pitch) with 35 teeth Pitch diameter (Dp) = P×Pitch diameter component
Calculation formulas for tooth gap varieties
As the most rational tooth gap varieties by which the strain angle changes in response towards the elongation of a smoothly rotated roller chain using the lapse of support time, ANSI specify two types of tooth profiles: U-type and S-type. In general, S-type tooth profiles are adopted in accordance with ANSI, and our regular sprockets also have S-tooth profiles.
