Product Description
Pulleyis divided into driving Pulley and reversing Pulley. Pulley is the main drive transmission portion of belt conveyor (belt conveyor), which is welded by barrel pores and skin and connecting plate. In basic, the belt conveyor Pulley with an outer diameter of considerably less than 320mm makes use of seamless steel pipe as the barrel skin, and the Pulley with an outer diameter of far more than 320mm is rolled with metal plate and welded to form the barrel skin, which is called welded Pulley Some forged steel connecting plates are welded with the cylinder skin as a portion of the cylinder, i.e. forged welded structural Pulley
Driving Pulley: it is the primary part of transmitting electricity. It can be divided into solitary Pulley (the wrapping angle of the belt to the Pulley is 210 ° ~ 230 °), double Pulley (the wrapping angle is up to 350 °) and multi Pulley (for higher energy). The Pulley can also be divided into steel smooth Pulley, rubber coated Pulley and ceramic Pulley. The smooth Pulley is easy to manufacture, but the downside is that the area friction coefficient is small. It is typically utilized in limited-length conveyors. The main benefit of rubber coated Pulley and ceramic Pulley is that the floor friction coefficient is big, which is appropriate for extended-distance big belt conveyor. Among them, in accordance to distinct surface area designs, the glue wrapping Pulley can be divided into: easy bread glue Pulley, CZPT (reticulate) glue wrapping Pulley and herringbone groove glue wrapping Pulley. Herringbone groove rubber coated surface has huge friction coefficient, great skid resistance and drainage, but it has directional requirements. Rhombic rubber protected surface area is employed for two-way conveyor. For Pulleys utilised in essential occasions, it is ideal to use vulcanized rubber surface area. When utilized underground, the rubber floor shall be produced of flame-retardant rubber floor content.
Pulley human body
The chemical composition and mechanical qualities of the metallic supplies utilized in the Pulley body shall comply with the corresponding countrywide requirements. Just before welding, the steel shall be shot peened by pretreatment method.
Hub
The casting good quality of the hub shall be subject to CZPT particle or ultrasonic inspection. For circumferential welds and longitudinal welds of small-diameter Pulleys, the specific method of one-sided welding and double-sided forming shall be adopted. All circumferential and longitudinal welds of the Pulley shall be welded with carbon dioxide fuel, and NDT shall be carried out to make sure the high quality of the welds. Eliminate the welding tension and guarantee the normal procedure of the Pulley.
Bend pulley
It is utilised to adjust the working direction of the conveyor belt or boost the wrapping angle of the conveyor belt on the transmission Pulley. The Pulley adopts clean rubber floor.
The Pulley shaft shall be forged and matter to NDT, and the flaw detection report shall be offered. The allowable torque and allowable resultant force shall fulfill the layout requirements.
Beneath the optimum load issue of the Pulley shaft, the deflection between the shaft and the bearing seat is not regarded underneath the situation of Pulley pores and skin stiffness
There are a lot of kinds of gears, and the most widespread classification method is by equipment shaft. Usually, there are three sorts of the parallel axis, cross-axis, and staggered axis. 1) Parallel shaft gears: like spur gears, helical gears, inner gears, racks, and helical racks, and many others. 2) Cross shaft gears: straight bevel gears, spiral bevel gears, zero-degree bevel gears, and many others. 3) Staggered shaft gears: There are staggered shaft helical gears, worm gears, hypoid gears, etc.
Gears are employed in a huge number of mechanical products. Most importantly, they supply gear reduction for motorized equipment. This is essential due to the fact usually small motors that spin quite quick can supply adequate electricity to the unit, but not adequate torque, the power that brings about an object to spin or twist on an axis. For case in point, an electric powered screwdriver has a very massive gear reduction (lowers the velocity of a rotating device (like an electrical motor)) simply because it needs a good deal of torque to switch the screw. But the motor produces only a small quantity of torque at substantial speeds. With gear reduction, the output speed can be reduced although growing the torque.
