Synchronous wheel selection for industrial belts

by:Uliflex     2020-09-24
There are two processing methods for industrial belt matching synchronous wheels, gear hobbing machine and wire drawing, gear hobbing machine has a much higher precision. Concentricity, equal-parameter industrial belt matching synchronous wheel selection.

The tooth profile model and pitch and other meshing parameters are the same as those of the synchronous belt (for details, please refer to: arc tooth synchronous belt or trapezoidal tooth synchronous belt). What needs to be determined is only the number of teeth (or diameter) and structure. Industrial belt matching synchronous wheel

Synchronous wheels for industrial belts: the main materials are aluminum alloy, gold carbon steel, stainless steel, nylon, etc., the selection of synchronous wheels for industrial belts

The number of teeth (or diameter) of the synchronous belt wheel is generally to determine the number of teeth of the small wheel first, and then determine the number of teeth of the large wheel according to the transmission ratio. Industrial belt synchronous wheel

In order to ensure the proper life of the timing belt, the diameter of the small timing belt wheel must be larger than the minimum allowable bending diameter in the table (see the webpage for details on the minimum allowable bending diameter of the timing belt), and then converted into the minimum number of teeth. As long as the structure and cost allow, considering the life of the timing belt, the number of teeth of the pinion is slightly more than the minimum number of teeth allowed. After the number of teeth of the small wheel is determined, the number of teeth of the big wheel can be determined according to the transmission ratio. Then determine the center distance of the two pulleys according to the structure, and calculate the pitch line length or the total number of teeth according to the pitch of the timing belt. At this point, the transmission parameters are all determined.

There are many types of timing belt pulleys. From the shape, they can be divided into flangeless B type (only the gear part BF with baffles at both ends and the gear part BS without baffles) and flange A type , That is, in addition to the gear teeth with baffles at both ends, there is a cylindrical flange (the AF type with baffle and the AS type without baffle). For details, please refer to the pulley page of the product center, industrial belt matching synchronous pulley

From the view of the way of coupling with the shaft, there are three types: screw, key and expansion sleeve (the so-called keyless coupling). The screw connection is simple and easy to assemble and disassemble, but the concentricity of the shaft wheel is poor, and the corresponding flat square or socket must be machined on the shaft; the advantages and disadvantages of the key connection are self-evident; the expansion sleeve connection performance is good, but the cost is high.

Industrial belts are matched with synchronous wheels. Standard parts are available from stock, and non-standard parts can be customized or processed with drawings. Synchronous wheel selection for industrial belts
