In order to supplement our wide range of belts, we also manufacture and supply a series of standard and customized pulleys for our V-belts and timing belts. Our pulley groove is made of cast iron or steel, which is cut by machine, with high precision, static or dynamic balance (depending on its size) reaching q6.3 level or higher, and circumferential (RIM) speed up to 40m / s.All pulleys provided by Raydafon are made of high-quality, dense grain gg25 gray cast iron or steel and then phosphate. Metric timing pulleys are also available from lightweight aluminum alloys with natural surfaces.Shaft fixing options vary according to size and the wide range of available materials, but as a standard, the range of pulleys includes taper holes, guide holes, or two types of holes.
Taper Lock Pulley InstallationThe installation of the taper lock pulley is an essential factor affecting the overall service life, which needs excellent carefulness. The following is a complete safety guide. As the two composed parts of the European standard pulley, the taper sleeve and the pulley also have a sequence during installation.
Named for tapered pulley sides that form a V-shaped groove, V-Belt Pulleys are transmission belts that transmit an engine's force to ancillary components, including alternators, hydraulic pumps, etc. Due to their relatively low-cost, V-Belt Pulleys are a popular option.As standard, V-belt pulleys are available in undrilled, pre-drilled, or clamping bush variants. The clamping bush variant, also known as a taper or taperlock variant, is always used in combination with the associated clamping bush. The undrilled and pre-drilled variants must first be provided with a borehole and possibly with a keyway and a threaded hole. The most common types of V-belt pulleys are SPZ, SPA, SPB, and SPC. They are stocked in both standard and clamping bush variants.
A timing belt pulley is a specialized pulley system with teeth or pockets along the outside of the pulley body's diameter. Like traditional pulley systems, timing belt pulleys are driven by frictional forces between the belt and pulley surfaces. The teeth or pockets outside the pulley are not used for power transmission. Instead, they engage the pulley belt, assisting with timing and averting misalignment.Timing belt pulleys are utilized when two shafts must be precisely linked for homogeneous rotation. Most traditional power transmission belts and pulleys are smooth, without teeth or pockets. The smooth belt can sometimes slip off the track, causing one shaft to turn while the other sits dormant. Timing belt pulleys eliminate this concern as teeth or pockets keep the pulley firmly attached to the belt during operation.Taper Lock Pulley Production ProcessA taper lock pulley manufacturing process includes the following steps:Forming a pulley: integrally forming a cylindrical pulley blank;machining V-belt grooves: cutting the external surface of the pulley blank to form a plurality of V-belt grooves matching a V belt;Fine machining: cutting the external surface of the pulley blank and the side surfaces of the belt grooves and cutting off a machining allowance;Shot blasting: Place the pulley in a shot blasting machine to form a rough shot blasting layer on the side surfaces of the V-belt grooves. The pulley manufactured through the above process has a high friction coefficient on the side surfaces of the belt grooves. It, therefore, has the advantage of preventing slippage and having high transmission efficiency.
