Excuse me, is the wheel a standard? Is there any place
New design equipment needs to be bought, and it needs to be broadly similar to the above data to fit in with the rest. If the requirement of the shaft coordinates is proposed according to the design consideration, it can also specify only one aperture range. In fact, unless the ready-made batch products accessories (such as small air compressor machine pulley), may find on the corresponding maintenance station, hardware few readily available on the market sell all kinds of belt pulley, perhaps in the old shop has removed the old parts can be suitable for use, with the basic data, draw a sketch, attached to the purchase plan more clear and convenient
If it is part of an existing equipment, it cannot be made from the original factory. It should basic dimensions: the original belt pulley shaft hole size and length, the size of the keyway (deserve to lock screw), the shaft hole end face and the distance to the belt groove groove number, use the v belt type (different models of the belt cross section is different, generally have annotations on a belt), the diameter of the pulley and other data to write clear, in order to match.
V-belt pulley (round) in addition to finalize the design all kinds of engines, machine tools and other accessories can be used as a standard order, the rest are non standard parts can't order directly, but according to design bidding. If it is triangle belt pulley on the existing equipment need to buy new, the simplest way is to purchase plan write clear equipment manufacturer, model, factory number, or date, and the position of the pulley, so get the original factory accessories, not easy to make mistakes;
