1. Standard sprocket
Regular sprockets are ANSI sprockets which could be engaged with standard series roller chains. See P125 for dimensions.
You’ll find two sorts of tooth profiles: U-tooth and S-tooth.
2. HK sprocket
HK sprockets is usually engaged with HK series roller chains, and people for single strand chains are identical to conventional sprockets. Having said that, sprockets for various strand chains are unique from common sprockets in sprocket tooth profile.
three. Other sprockets
Other sprockets are developed in accordance for the following calculation formulas to suit respective specialty chains.
The sprockets applied for that following chains will be the very same as the typical sprockets in tooth gap type, but different in tooth thickness (sprocket tooth profile).
4. Calculation of sprocket dimensions
The dimensions of typical sprockets as well as other general sprockets are calculated as follows. At the outset, the diameters of sprockets are calculated from the following calculation formulas.
Subsequent, sprocket tooth profile (the form of your tooth determined by its thickness) is calculated in the following calculation formulas. (The values proven inside the following pages had been calculated by these formulas and thought to be the common values.)
Calculation formulas for diameters and tooth gap varieties Calculation formulas for diameters
Calculation of pitch diameter, tip diameter and caliper diameter
The fundamental dimensions of the sprocket suitable for any chain pitch of one mm are respectively identified as pitch diameter factor, tip diameter factor and caliper diameter element. The respective things for respective numbers of teeth are listed beneath. If these variables are multiplied by chain pitch, the fundamental dimensions with the corresponding sprocket is often obtained.
Example:
Inside the case of 80 (25.forty mm pitch) with 35 teeth Pitch diameter (Dp) \uff1d P\u00d7Pitch diameter component

the most rational tooth gap kinds through which the stress angle alterations in response on the elongation of a smoothly rotated roller chain with the lapse of service time, ANSI specify two kinds 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.<\/p>","protected":false},"excerpt":{"rendered":"
