Timing belts imperial pitch

Product catalog summary

Overview: This document outlines the technical specifications and characteristics of timing belts, focusing on their construction, dimensional attributes, and typical applications.

Belt Construction Characteristics:

Resistive Insert: The belt's core is made from a high-strength, inextensible material, spirally wound to define the pitch line and bear loads.
Body of the Belt: Constructed from neoprene, it provides excellent resistance to fatigue, heat, and mineral oils.
Tooth Covering: A nylon fabric reduces friction and enhances transmission efficiency, offering increased lubrication during operation.

Dimensional Characteristics:

Pitch Line Length: Measured along the resistive insert axis.
Pitch: The distance between two contiguous teeth axes, essential for matching belt and pulley pitches.
Width: Determined by the power to be transmitted, with pulleys slightly wider to accommodate tolerances.

Definitions and Symbols:

lp: Pitch line length
P: Pitch
Lc: Belt width
Lp: Pulley width
Z: Number of teeth
Dp: Pulley pitch diameter
De: Outer pulley diameter

Common Applications:

Belt Pitch: Different pitches are suitable for applications like precision machinery, typewriters, calculators, and household appliances.

Specifications:
Belts operate within -25°C to +85°C and tolerate small oil amounts. Avoid sharp bending or tight wrapping to prevent reinforcement layer damage. All belts have a ground back, and for special applications, consult engineers for different thickness or tolerances.

Standard Tolerances:
Standard width tolerance for XL-L and H belts is specified in inches and millimeters. For XXH belts, the width tolerance is +8 mm for any width or length.

Nominal Thickness:
Nominal thickness on the tooth is specified for belt types (XL, L, H, XH, XXH) with tolerance degrees.

Recommendations:
For conditions not covered in the graph, contact technical support. For fixed axis-to-axis transmissions or special tolerances, consult technicians.

Graphical Data:
A graph is included for selecting belt pitch, showing corrected transmission power (Pc) in kW and revolutions per minute of the smallest pulley.
