Title : Buy high-tolerant timing pulleys at the lowest price from Emechmart
The timing pulleys are made of rubber with hardened teeth that can interlock with the camshaft and crankshaft cogwheels. It is an integral part of the internal combustion engine responsible for synchronizing the rotation of the camshaft and crankshaft. This enables the engine's valves to properly open and close during both the intake and exhaust strokes of each cylinder.
The Belts pulleys also play an important role in preventing the pistons from hitting the valves. A timing belt is usually a toothed belt with teeth on one or both sides of the surface.
Effective Timing pulley design at Emechmart
At Emechmart, a timing pulley has two main components: a molded cord inside the timing belt to carry the torque load, and a plastic compound used to shape the teeth and cover the cord. These components are available in a variety of materials for different types of timing belts. In determining the type of material to use, the end use of the belt has to be considered. Timing pulleys are typically made of fiberglass, polyester, or Kevlar. They transmit power to the drive system via belts. Emechmart is the best place to buy timing pulleys online that boost up your production capacities.
Timing pulley teeth for synchronized shaft
The robust timing belt teeth are reliable for keeping the crank and cam shaft synchronized, and there is a wide range of metric pitches for the teeth. Pitch is the distance measured from the center of one tooth on the timing belt to the center of the next adjacent tooth. The pitch affects other timing belt pulley factors including the number and diameter of the teeth. When it comes to tooth design, older timing belts are designed using trapezoidal shaped teeth.
Things to consider for buying timing pulleys
The first thing is to determine the peak torque for the drive. This is mostly the starting torque of the motor. However, there may also be transient or shock loads which are abnormal during normal operation.
The second thing is determining the largest diameter of pulley that can be used. This is done keeping in mind the space constraints and the drive ratio of the system. This helps by increasing the torque capability of the drive and increasing the service life of the belt.
Selection of tooth profile
The third thing is the selection of the tooth profile of the belt. If, for the selected profile, the peak drive torque is at the upper limit of the torque transmission capability, consider using the next higher torque rated profile. For the selected profile, find the relevant pitch. To calculate the required number of teeth of the belt, this value will be needed.
Calculation of T.I.M
Calculate TIM (Teeth in Mesh), given the teeth in mesh factor. The peak torque of stage 1 should now be divided by T.I.M. Factors for determining the design torque. An important point to note is to double check the belt pitch to ensure that this adjustment in torque has not taken your application out of pitch range.
Belt Pitch Length
This involves calculating the belt pitch length based on the drive's design center distance.
Length Division and Belt Pitch
The sixth thing consists of dividing the belt pitch length by the selected tooth pitch and rounding the result to the nearest whole number. This will be the number of teeth on the belt for this application. The nominal center distance of the drive design must be adjusted to match the belt.
Calculation of Effective Stress
This seventh thing calculates the effective tension (T) on the drive using the pitch radius of the loaded pulley and the design torque that is the smallest in the system.
The power factor for the application is selected. The effective tension from step seven is divided by the strength factor to determine the required break strength for the belt design. To represent a double span break, multiply by 2. To determine the type of reinforcement and the width of belt required, consult the break strength table. The values listed in the table must exceed the break strength for the design.
Choosing the Width of the Belt
This step involves selecting a belt width that is capable of handling the design torque with the selected pulley size. An important point is that the width of the belt required for the system will be a multiple of two widths.
