belt tensioner

Cars are complex machines with numerous components working together to keep you cruising smoothly down the road. One such component that plays a vital role but often remains in the shadows is the belt tensioner. A belt tensioner is a small but crucial part of your car's engine system. It's responsible for keeping the engine's belts at the right tension. Now, you might be wondering, what's the big deal with belt tension? Well, it's a pretty big deal. The belts in your car drive essential components like the water pump, power steering pump, and, most importantly, the alternator that recharges the battery. Without proper tension, these belts can slip or become too tight, causing a range of issues.

A bearing is a machine element that constrains relative motion to only the desired motion and reduces friction between moving parts. The design of the bearing may, for example, provide for free linear movement of the moving part or for free rotation around a fixed axis; or, it may prevent a motion by controlling the vectors of normal forces that bear on the moving parts. Most bearings facilitate the desired motion by minimizing friction. Bearings are classified broadly according to the type of operation, the motions allowed, or the directions of the loads (forces) applied to the parts. The term "bearing" is derived from the verb "to bear"; a bearing being a machine element that allows one part to bear (i.e., to support) another. The simplest bearings are bearing surfaces, cut or formed into a part, with varying degrees of control over the form, size, roughness, and location of the surface. Other bearings are separate devices installed into a machine or machine part. The most sophisticated bearings for the most demanding applications are very precise components; their manufacture requires some of the highest standards of current technology.

The tensioner is divided into accessory tensioner (generator belt tensioner, air conditioning belt tensioner, mechanical supercharger belt tensioner, etc.) and timing belt tensioner according to the location. The tightening wheel can be divided into mechanical automatic tightening wheel and hydraulic automatic tightening wheel according to the tightening way.

1, position: auto tensioner is generally arranged on the inside of the loose edge, so that the belt is only subject to one-way bending; At the same time, in order to ensure that the envelope Angle of the small belt pulley is not reduced too much, the tension wheel should be installed as close as possible to the large belt pulley. 2, function: serpentine belt pulley is a belt drive tension device, when the center distance of the belt can not be adjusted, you can use the tension wheel to tighten the belt. 3, composition: timing tightening wheel is mainly composed of fixed shell, tensioning arm, wheel body, torsion spring, rolling bearing and spring sleeve, etc., can automatically adjust the tension according to the different tightness of the belt, so that the transmission system is stable, safe and reliable.

In order to maintain proper belt tightening force, avoid belt slip and compensate the elongation caused by belt wear and aging, a certain torque is required in the actual use of the tightening wheel. When the belt tension wheel is running, the moving belt may cause vibration in the belt tension wheel, which can cause premature wear of the belt and tension wheel. To this end, a resistance mechanism is added to the tightening wheel. However, because there are many parameters affecting the torque and resistance of the tightening wheel, the influence of each parameter is not the same, so the relationship between the parts of the tightening wheel and the torque and resistance is very complicated. The change of torque directly affects the change of resistance, and is the main influencing factor of resistance, and the main influencing factor of torque is the parameter of torsion spring. Properly reducing the middle diameter of the torsion spring can increase the resistance value of the tension wheel.

The Belt tensioner is divided into accessory tensioner (generator belt tensioner, air conditioner belt tensioner, supercharger belt tensioner, etc.) and timing belt tensioner according to the location of occurrence. The belt tensioner is mainly divided into mechanical automatic belt tensioner and hydraulic automatic belt tensioner according to the tensioning method.

Tension pulley is a vulnerable part of spare parts such as automobiles. The belt is easy to be stretched after a long time. Some alternator tensioner pulley can automatically adjust the tension of the belt. In addition, with the belt tensioner pulley, the belt runs more smoothly and the noise is small. , and can prevent slipping. The function of the timing belt idler pulley is to adjust the tightness of the timing belt, and it is generally replaced together with the timing belt to avoid any worries.

The main function of the idler pulley is to change the steering of the driven wheel, increase the transmission distance, adjust the pressure angle, etc. The belt idler pulley is a part of the gear train that plays a transitional role and will not change the transmission relationship. It is to make the force of the gear train more reasonable or to meet the layout of the entire transmission system. Its function is only to change the steering, but not to change the transmission ratio. The wheelbase can be extended through the v belt tensioner pulley. The number of its teeth has no effect on the value of the transmission ratio, but it will have an impact on the steering of the last wheel.
