Precision Power Transmission, Double-Pitch Power Transmission, and Double-Pitch Conveyor Roller Chains, Attachments, and Sprockets
$105.00

This Standard is a consolidation andrevision of three ASME Standards: ASME B29.1M Precision Power Transmission Roller Chains, Attachments and Sprockets; ASME B29.3M Double-Pitch Power Transmission Roller Chains and Sprockets; and ASME B29.4M Double-Pitch Conveyor Roller Chains, Attachments and Sprockets.

B29.1 Precision Power Transmission Roller Chains, Attachments and Sprockets: This Standard covers transmission roller chains, attachments, and sprockets. A roller chain is a series of alternately assembled roller links and pin links in which the pins articulate inside the bushings and the rollers are free to turn on the bushings. Pins and bushings are press fit in their respective link plates. Roller chains may be single-strand or multiple strand. Tables are also provided for (a) General chain dimensions; (b) Maximum width over regular pin; (c) Dimensional limits for interchangeable chain links; (d) Straight- and bent-link plate extension dimensions; (e) Sprocket-tooth section profile dimensions of commercial and precision sprockets; (f) Extended pin dimensions; (g) Maximum eccentricity and face runout tolerances for commercial and precision sprockets; (h) Sprocket flange thickness; (i) Seating curve dimensions and tolerances; (j) Minus tolerances on caliper diameters of commercial and precision sprockets; (k) Pitch diameter, outside diameter and measuring dimension factor for chain of unity pitch; and (l) Whole depth of topping hob cut WD for each pitch and range.

B29.3 Double-Pitch Power Transmission Roller Chains and Sprockets:. This Standard describes a limited series of double-pitch power transmission roller chains which supplements the base chain series conforming to the Standard B29.1. These chains differ from the base chains only in pitch, which is double that of the corresponding base chain. A double-pitch power transmission roller chain is a series of alternately assembled roller links and pin links in which the pins articulate inside the bushings, and the rollers are free to turn on the bushings. Pins and bushings are press-fitted in their respective link plates. Supplementary information in Appendix A on speed and power transmission ratings indicates their special usefulness for drives operating at slow to moderate speeds, with moderate loads and long center distances.

B29.4 Double Pitch Conveyor Roller Chains, Attachments and Sprockets: This Standard covers a series of alternately assembled roller links and pin links in which the pins articulate inside the bushings and the rollers are free to turn on the bushings. The pitch of link plates is twice that of the link plates of the base series chain. Pin link plates and roller link plates have identical, straight-edge contours. There are also Tables for (a) General dimensions, measuring loads and ultimate tensile strengths; (b) Ultimate dimensional limits for interchangeability; (c) Dimensional limits for straight- and bent-link plate extensions with one or two attachment holes; (d) Dimensional limits for conveyor chains with extended pin; (e) Sprocket tooth section profile dimensions; (f) Minus tolerances on the bottom or caliper diameters of sprockets for various numbers of effective teeth; and (g) Sprocket factors for small and large roller series.
