· The basic components of a mechanical convey system include a drive motor through a gear and/or chain reducer, connected to a drive device, such as a roller or a sprocket. The energy of the motor is transferred directly to the conveyor, which is in direct contact with the material. Mechanical conveyors can be opened or closed to the atmosphere, with hundreds of moving and working parts.
Radial load is negligible at the conveyor tail shaft. However, drive ends (unless integrated with the conveyor end plate) are subject to radial loading due to overhung drive loads, such as chain sprockets or shaftmounted speed reducers. Thrust is the reaction, through the conveyor screw or screws, resulting from movement of the material. Therefore, the end bearing must prevent axial movement ...
Select a chain drive to transmit kW from a gearbox running at 80 rev/min and driven by a directonline electric motor, to a uniformly loaded conveyor drive shaft which is required to run at approximately 40 rev/min for 12 hours per day. Gearbox output shaft is 35mm and the conveyor headshaft is 65mm diameter. (a) Service Factor From Table 1 the Service Factor is (b) Design Power = 1 ...
· Dual Drives. Conveyors driven by two pulleys, usually in tandem, offer a number of design advantages. They also compromise the design with some not too clear tradeoff conditions on reliability, performance, and cost. The questions concerning 1) when the dual drive should be considered, and 2) what configuration of size and quantity offers the greatest utility are the objectives of the ...
· The biggest innovation is the drive or live roller conveyor, where each roller is connected to a motor via a belt/chain/shaft to increase controllability. This equalizes the rate with which materials move down the pathway, and also allows these conveyors to have limited use in reverse, from low to high elevation. They can work well in bidirectional appliions, as the rollers can direct ...
The standardization of drives is the key to most successful conveyor systems. The problem is however that some drives have to be drastically oversized to obtain some degree of conformity. By considering this point at an early stage in the design process. it is usually possible to overcome the problem, therefore simple cost analyses of all the possible solutions can quickly decide on the drive ...
Along with the ratios available a wide selection of outut speeds are achievable with the use of a belt drive to the inut shaft. This new generation of gearbox is available in 13 case sizes. Range: Power range up to 280kw, Ratio 20:1 Type: Helical Hardened and Ground Gears. Appliion: Horizontal Stirrers or Mixers Conveyors.
· Stepper, servo, ac, and dc motors can meet most industrial automation requirements, but the ideal motor depends on the appliion. Whether it's a constant speed, variable speed, or position control appliionusers should work closely with the motor and drive the supplier to select the right motor for the appliion.
Mechanical conveyors can be opened or closed to the atmosphere, with hundreds of moving and working parts. Pneumatic or Mechanical Conveyors: Determining the Best Method for You The most important factor when selecting a type of conveyor is the form of material to be transferred. Identifying the key characteristics of your material will help ...
· For active speed control of belt conveyors, it is important to select a suitable belt speed profile. ... Fig. 1b illustrates the one dimensional model of a single drive belt conveyor system. According to Newton's Second Law, the motion of a belt conveyor can be described as (8) M x ¨ + C x ̇ + Kx = F where M is a matrix of mass, x ¨ is a vector of nodal acceleration, C is a matrix of ...
· 4) Smooth ceramic lagging is the optimal choice for nondrive head pulleys; it has a flat, even surface for the belt and belt cleaners to run efficiently. There aren't many negatives to consider when installing ceramic lagging, but it is best to get expert help when choosing the right type of lagging for your belt conveyor system. For example ...
· The Rexroth ActiveMover linear motor conveyor system serves as an alternative to traditional power and free palletbased assembly conveyors in select lightpayload appliions than can justify the upfront cost. Linear motor conveyors (also called intelligent track or transport systems) are suitable for moving items at high speed and positioning accuracy.

Drive pulleys are primarily responsible for driving the belt around the conveyor, whereas the nondrive pulleys redirect the belt. More grip is required by a drive pulley than on nondrive pulleys. Depending on your design, you may consider using rubberbacked ceramic or direct bond ceramic lagging because they both have superior belt grip, and ceramic lagging is generally a tougher and longer ...
There are a number of factors to weigh when selecting a conveyor system for process industries. Often, design concepts are foremost in mind – taking into consideration things like layout and optimal throughput. Sometimes overlooked in the course of building out a conveyor system are the individual components of the machinery itself. In some ways, it might be comparable to buying a new car ...
