Belt Pulley Smooth Running, Low Noise, Low Vibration

Nov 06, 2017

Belt Pulley belongs to the disk hub-type parts, general relative size is relatively large, manufacturing process is generally casting, forging mainly. General size larger design for the use of casting method, the material is generally cast iron (casting performance is better), very little use of cast steel (steel casting poor performance); Generally small size, can be designed for forging, material for steel. Belt Pulley indicators and material selection is to be able to meet the requirements of the premise of minimizing the raw materials, process feasible, the lowest cost selection principle! The Belt Pulley is mainly used for long-distance transmission power occasions, such as small diesel engine power output, agricultural vehicles, tractors, automobiles, mining machinery, machinery processing equipment, textile machinery, packaging machinery, lathes, forging beds, some small horsepower motorcycle power transmission, agricultural machinery power transmission, air compressor, reducer, reducer, generator, Gin and so on.

The advantages of Belt Pulley drive are: the belt Belt Pulley drive can reduce the load impact, the belt Belt Pulley Drive runs stably, the low noise, the low vibration, the belt Belt Pulley transmission structure is simple, the adjustment is convenient; the Belt Pulley drive is not as strict as the meshing drive for the manufacture and installation accuracy of the Belt Pulley. Belt Belt Pulley drive has overload protection function The belt Belt Pulley drive has a large adjustment range of the center distance between the two shafts. The disadvantage of belt drive is: Belt Belt Pulley drive has elastic sliding and skidding, low transmission efficiency and can not maintain accurate transmission ratio; The belt Belt Pulley drive transmits the same large circumference force, the contour dimension and the axial pressure are larger than the meshing drive; the belt Belt Pulley belt has a short life span. All kinds of mechanical equipment Belt Pulley diameter and other dimensions are their own according to deceleration ratio, according to the work speed and motor speed of their own design. Working speed/motor speed = Follower diameter/active wheel diameter * 0.98 (sliding coefficient), if the use of steel as a material Belt Pulley, the request line speed is not higher than 40m/s, such as the use of cast iron materials, the demand line speed is not higher than 35m/s, motor speed and Belt Pulley diameter conversion ratio, speed ratio = output speed: input speed = Load belt Belt Pulley pitch diameter: motor Belt Pulley-round diameter.
