Fig. The main types of conveyors, plate type: A — smooth disjoint (When moving unit loads); B — smooth connected (To move a single and loose cargo); And a flangeless winding (To move bulk and unit loads); G — side winding; D — box-small E — large box (To move bulk cargo)
the Types of all the conveyors are in two versions:
-
the
- Rollers in the composition of the chassis the
- the Rollers are missing
the support Rollers (i.e. rollers) act as part of the structure.
Pair of roller chains-plates represent the traction composite plate conveyor. And running the support mechanisms for flooring and chain are rollers. They have to be installed on the bearings of the swing or motion. They are grouped according to mean rail level, with one or two reborrow.
Tire that indicates the direction you can make from angles, channels, and rail – it depends on the measure voltage. The device blocks or stars formed from the traction part.
Spiral spring or simply a screw mechanism as tension structures mounted on end sprockets. In addition, double-chain conveyors of one of these stars wear on the shaft without using a key to guarantee its self-a chain of joints.
Reducer, motor and sprocket make up the conveyor drive of the specified kind. The sprocket has five to eight teeth. (dopolnitelnaya information is available at https://www.rusconveyor.ru)
Disadvantages are:
-
the
- difficulty in use due to the large number of chain hinges and rollers the
- relative unavailability of traction parts with the flooring due to the expensive pricing the
- the importance of mass flooring
And the advantages of plastic conveyors include:
-
the
- guarantee high efficiency and a wide area of travel on various routes the
- the probability of moving hot and lumpy loads, including steeply-sloping land (about 60°).
Calculate the parameters of the breadth of the deck, to pick up a tractor part and to determine the strength of the motor.
During the measurement of the indicator latitude Bezborodova smooth flooring cover is transported in the cross-section takes the shape of a triangle (Fig.a).
Speed traction part, when you install the geometric characteristics of the plate conveyor believe in the area from 0, 01 to 1.0 m\s due to the fact that the action with high speed can lead to higher dynamic stresses.
For conveyors with immovable sides (Fig.b) that transporterowych loose goods need to take into account the applied resistance, which is created by friction of the cargo on Board.
Advised this representation to detect this resistance (N) note. The minimum response is the heavy chain with rollers of larger diameter.
Then calculate the size of stars, the traction and the power of the electric motor.
When selecting the chain you need to understand that if the traction strain is produced by a pair of chains, one chain is considered uneven, placing it on a chain.
When the transport speed is greater than 0, 2 m\s, then the circuit needs to take a calculated voltage with the addition of dynamic domnarski by the formula
