Ring Gears are available in many different sizes. The gear ratio is the number that represents the size of the Ring Gear as compared to another Gear Drive. This ratio determines how many rotations it will spin before the wheels will turn. Lower gear ratios cause the wheels to spin more often than higher gear ratios.
In an automobile, the Ring Gear can also affect the overall fuel economy. Most performance cars have lower gear ratios, which increases the acceleration of the car. This added performance comes at the cost of gas mileage.
Most large trucks require a lower Ring Gear ratio for increased towing force. This force is best described as the torque capacity of the vehicle. The gear ratio directly affects the torque capacity as it creates more movement and power at a lower RPM.
A Ring Gear can be best described with a gear on a bicycle. The wheels of a bike spin easiest with smaller gears but they require more rotations to move forward. As the gear is adjusted into a larger, lower gear ratio it becomes difficult to turn the wheel, but more acceleration is produced with fewer rotations.
We are with more than 20years of experience in customized machinery parts manufacturing. Our products include shafts, gears, investment casting parts, and many kinds of precision CNC machining parts. We are also professional in bearings— Track roller/wheel, guide roller, unground bearing, non-standard precision bearings— Design and supplying.
We refuse low quality products. We were competing against other suppliers with our professional and perfect products and service. We are committed not only to be your supplier, also to be your engineer based on our rich experience in customizing machinery parts field, we know better solution for different material, different tolerance, different order quantities. A wide arrange of parts can't be listed here, please don't hesitate to contact us for professional supports.
