May 13, 2015· I want to select a motor for a conveyor or machine, for Load torque calculation, i need the weight of the parts which has to move by motor. Now the problem is that,can i simply take full weight of all parts which has to move or carry? or is there is any specific method to take weight of all parts like chain, shaft, belts ? for example like: if there is shaft with pulleys on two pillow blocks ...
calculations. At long belt conveyor systems however, strain is introduced into the belt leading to elastic waves traveling through the belt causing increased loads. The longer a belt system is, the larger the stresses will get. Therefore, it is important to consider different dynamic load

Chain Construction The Roller Chains generator is intended to design chain drives with roller and bush chains. The chains can have single strand or multiple strands. The double-pitch chains are also supported. Typical construction of roller and bush chains is shown in the following picture. The main difference is that bush chain does not have a roller
wave modelling [31 have been applied successfully to many conveyor installations. Dynamic analysis can generate data on almost all aspects of the conveyor operation including starting and stopping tensions and velocities, take up movement, load sharing between drives, drive and brake drum slip etc.
4.4 Equivalent load 4.4.1 Dynamic equivalent load When both dynamic radial loads and dynamic axial loads act on a bearing at the same time, the hypothetical load acting on the center of the bearing which gives the bearings the same life as if they had only a radial load or only an axial load is called the dynamic equivalent load.
The durability of bearings is the decisive factor which influences the durability of idlers for belt conveyors. A typical design solution of an idler is presented in Figure 1 below. Download : Download full-size image; Fig. 1. Smooth idler for a belt conveyor with a labyrinth seal

Trippers are an integral part of the conveyor system, which simplify the multiple discharge requirement of bulk material being conveyed. Trippers include of an elevated platform con-sisting of idlers mounted on a supporting structure. The mate-rial is further discharged into chutes, so as to convey the mate-rial to another conveyor or storage area.
Each conveyor element can have a unique idler set (up to eight different idler sets can be entered). This allows impact idlers, transition idlers, and other idler sets to be entered and included in the output report. Pipe conveyor design and other advanced features are also included.

The data acquired from DMA testing is processed by a special program to generate master curves and then incorporated into Beltstat software for conveyor calculations. This is our proprietary program. Conveyor Dynamics, Inc. (CDI) has been developing this technology, applying it to conveyor design, and accumulating verification data since the 1989.
In order for conveyor idlers to work according to expectations, correct design of idler parameters such as roller shaft and bearing specification and cross member specification for idler frames. As a quality manufacturer of idler frames, Melco ensures thorough idler calculations to ensure all conveyor operation parameters are taken into ...
Helix delta-T uses a Finite Element model of the conveyor to perform the dynamic analysis. The conveyor is broken up into segments, and for each segment, we use a Kelvin solid model, which is a spring in parallel with a viscoelastic element, as shown below: Kelvin Solid Model. Conveyor …
L = conveyor length (m) ε = belt elongation, elastic and permanent (%) As a rough guideline, use 1,5 % elongation for textile belts. and 0,2 % for steel cord belts. Note: For long-distance conveyors, dynamic start-up calculations. may be required, because not all elements are set in motion simultaneously,
c = dynamic load rating (N), see page 14 P = load on bearing (N) = 9.8 F/2 (F in kg) n = rotational speed (min-1) = 60V/3.14xD D is the roll diameter (m) 2. This selection procedure ensure that theoretical bearing life is above 20,000 hours and is dependant on the bearing load, type of …
Factor A and Factor B depend upon the trough angle of the belt conveyor carry-ing idlers, as indicated below: Formulae (2) and (3) are used for avoiding zero tension in the belt edges, and should be applied to the operating empty belt. Formula (4) is used to prevent …
