Other conditions such as layout restrictions.

Design Power Calculation:

Design power (Pd) is calculated using transmission power (Pk) and various correction factors: load (Ko), idler use (Ki), speed increase (Ks), start-stop frequency (Ka), and operation environment (Ke).
Formula: Pd = Pk × (Ko + Ki + Ks) × Ka × Ke.

Belt and Pulley Selection:

Select a belt size based on design power and small pulley revolution using simplified selection tables.
Select belt width and number of teeth for the small pulley from standard transmission capacity tables, ensuring compatibility with shaft diameter and avoiding colored areas in tables.
Determine the number of teeth for the large pulley based on speed ratio and verify bore diameter.

Belt Length and Center Distance:

Calculate approximate belt length (L') and select the closest belt length from available types.
Calculate center distance (C) using selected belt length.

Correction for Meshing Teeth:

Ensure the number of meshing teeth is 6 or more; if less, apply a correction factor from Table 6.
Engagement angles for drive and idler pulleys should be 120° or more and 90° or more, respectively.

Verification of Belt Width:

Ensure the belt width satisfies the design power or torque requirements using factors for belt width (Kw), meshing correction (Km), and belt length (KL).

Design Torque Calculation:

Design torque (Pt) is calculated similarly to design power, using transmission torque (Pm) and correction factors.
Formula: Pt = Pm × (Ko + Ki + Ks) × Ka × Ke.

Specifications and Calculations:
The document provides detailed calculations for determining belt length (L') and center distance (C) for a timing belt system. The approximate belt length is calculated using the formula L = 2C + 1.57(Dp + dp), where Dp and dp are the pitch circle diameters of the large and small pulleys, respectively. The center distance is calculated as C = (B + √(B² - 2(Dp + dp)²))/4, where B is the belt length minus 1.57 times the sum of the pitch diameters.

Design and Selection Guidelines:
The document outlines the selection process for timing belts, including the determination of belt size, number of teeth, and belt width. It emphasizes the importance of guide flanges to prevent axial deviation of the belt and provides guidelines for their installation based on the type of transmission (horizontal, vertical, or multiple-shaft).

Use of Idlers:
