Bucket elevator tensioning device redesign

Bucket Elevator tensioning device redesign :
Since bucket elevator has a small footprint , full sealed transmission, reduce environmental pollution, is commonly used in conveying bulk material handling equipment .
Bucket elevators work in order to stabilize the normal operation of the traction needed for tensioning member tensioning force is called the tension generated ; keep running tension is called the minimum initial tension , the tension is too early to accelerate parts wear in , initial tension is too small , traction wheel slip or towing parts and pieces of deflection , is not working properly . Tractor parts with tape, ring chain , plate chain several structures , performance is not the same, so the selection of the tensioning method is also different , the current methods commonly used tensioning screw tensioning tensioning lever hammer , hammer tensioning , composite tension and so on.
Screw mounted on the lower part of the chassis , nut U-shaped groove in the support plate , when the rotary screw , they can move the support plate , the lower bearing is fixed on the support plate, thereby enabling lower tension roller to pull pieces . This method is suitable for tensioning the tape for traction member using bucket elevators , the tape a certain degree of flexibility , when given elongation , the adjustable tensioning screw , in order to ensure stability of the work tape .
The hammer lever tensioning force acts on the support plate , fixed to a lower bearing support plate , so that the lower part of the pulling element driven sprocket taut. This is an automatic tensioning device , hammer follower lever has a certain resistance, traction member to stay in the skin with a certain tension, so that the stable operation of the drive in the chain hoist is usually applied to avoid slipping off the chain and the application effect.
Tensioning hammer , hammer gravity via the bracket directly to the lower bearing housing , the pulling of the lower driven sprocket member taut, and the hammer lever tensioning methods, to achieve the same tension , more weight . So commonly used in weight pulling pieces larger plate chain hoist in position space is small, automatic tensioning method .
Composite tension , combined with the spring hammer , pressure in the lower bearing seat, so that the lower part of the traction drive wheel parts taut, composite tension in between the hammer and the lower bearing housing plus a set of spring , so too rear axle when wearing a certain buffer , suitable for use in traction hoist pieces larger self , the use of attention on both sides of equal weight hammer block , avoid heavy.
