Item Description

Merchandise data

Solution materials: HT200

Appropriate for: mechanical lathes

Merchandise introduction: the advantages of pulley travel: pulley travel can relieve the impact of load Pulley push operating efficiently, reduced sound, minimal vibration The composition of the pulley travel is simple and straightforward to modify. Pulley transmission for pulley producing and installation accuracy is not as strict as meshing transmission The pulley transmission has the purpose of overload defense The adjustment range of middle distance between two shafts of pulley transmission is huge. The negatives of belt drive are: pulley generate elastic sliding and skid, minimal transmission effectiveness and can not keep accurate transmission ratio When the pulley transmission transmits the identical massive circumferential drive, the contour size and the stress on the shaft are bigger than that of the meshing transmission. Pulley generate belt has shorter lifestyle

Pulley:

Pulley, belongs to the wheel hub course areas, typically relative size is relatively huge, the producing approach is generally solid, forging. The common size of the greater layout for the casting technique, the materials is normally solid iron (casting efficiency is excellent), rarely cast steel (metal casting overall performance is not great) Normally tiny size, can be developed for forging, the substance is steel

Manufacturing requirements

Pulley substance and generation demands

1. The belt pulley employed for the ventilator is produced of grey solid iron HT200,HT250, and so forth. (but steel, copper, aluminum, and many others., can also be utilised according to CZPT er demands).

2. The pulley ought to meet up with: light bodyweight, uniform mass distribution, eradicate the interior tension produced in the producing, pulley should be static balance correction.

The belt specification

The technical specs of the triangle belt are divided by the dimension of the back again width (leading width) and the height (thick). According to the distinct dimensions of the back width (top width) and the height (thick), the nationwide normal supplies the O, A, B, C, D, E and other types of the triangle belt. The part width, top width and top of each and every type of the triangle belt are not the exact same. So the pulley must be created in accordance to the shape of the triangle belt a variety of groove These different slots. It determines the pulley O pulley, A pulley, B pulley, C pulley, D pulley, E pulley and other kinds of pulley.

1. Clear the shaft, the interior and outer holes of the bushing, and the inner hole of the hub. Eliminate any oil, paint or grime, location the bushing on the hub, and match the half holes to make complete holes (every single complete gap will only be threaded on a single aspect). Lightly oil the threads and factors of established screws or the threads and heads of cap screws. Loosely spot the screws in the threaded holes on the hub aspect. Make confident the bushing is free on the hub. Snap the assembly onto the shaft and situation it in the preferred position. Tighten the screws alternately and evenly until finally all are limited 5. Hammer the big end of the bushing with a hammer and block or socket to keep away from harm. The screw can now be turned a bit to the specified torque setting. Repeat this alternating hammering and screw retightening right up until the specified torque is arrived at. Fill all holes with grease to get rid of dirt.
