1Unit item handling conveyors transports A Coal B Chemicals

1-Unit item handling conveyors transports:

(A) Coal (B) Chemicals (C)Corn (D) CD jewel box castings

2-The drive method where each roller has an internal motor and gearbox for roller conveyors is called:

(A)Self-contained motor-in-roller drive (B) Direct drive (C)Roller-to-roller drive (D)Sliding contact drive

3-U-Joints are used for many applications rather than flexible coupling because they allow the transmission of power at

(A)Lower angles (B)Greater angles (C)Right angles (D)Zero angles

4-Plastic-chain couplings generally use:

(A)Polyester chain (B)Polycarbonate chain (C)Silicone chain (D)Nylon chain

1-List five PT (Power Transmission) components for a typical troughing belt conveyor?

2-List one coupling for each category below and describe their components, and misalignment type(s) that they could accommodate.

Mechanical flexible couplings

Elastomeric flexible element couplings

Metallic element flexible couplings

Please do it all of them hear ((DO NOT WRITE IN A PAPER))

Solution

1 Answer. D CD Jewel box casting

2.Answer A self contained motor in roller drives

3.Answer. B Greater angle

4; Answer D nylon nylon chain

1Power transmission components

Conveyor belt

Impact older

Impact roller

Carrying idler

Return idler

2.Couplings

A. Mechanical flexible couplings

Type chain coupling

Two gear sprockets with hardened sprockets teeth by double width chain

B Elastomeric coupling

Type Elastomeric compression

An Elastomeric medium used to transmit torque and accommodate misalignment

Main components are hubs and spider

Spider is a elastic medium

C Metallic element coupling.

Diaphragmcojpling Transmission of power through two flexible metal diaphragms they bolted to the outer rim of the shaft hubs and connected via spacer tube

Misalignment is absorbed by diaphragm members
