A double worm reduction gearbox is a type of gearbox that is commonly used in industrial applications. It comprises two worm gears that work together to reduce the input speed and increase the output torque. One of the key design considerations of a double worm reduction gearbox is the amount of backlash present in the gears. Backlash is the amount by which the width of the gear teeth exceeds the pitch of the teeth. This article will explore how to calculate the backlash in a double worm reduction gearbox and its significance.
Background
What is a Double Worm Reduction Gearbox?
A double worm reduction gearbox is a type of gearbox that uses two worm gears to reduce the speed of the input shaft while increasing the output torque. The two worm gears are positioned at right angles to each other, allowing them to transmit power and motion at a 90-degree angle.
Calculating Backlash in a Double Worm Reduction Gearbox
What is Backlash?
Backlash is the amount of clearance or play between the teeth of two meshing gears. It is defined as the difference between the thickness of the gear tooth and the width of the space between the teeth in the mating gear. Backlash is an important parameter in gear design since excessive backlash can cause vibrations, noise, and reduced precision in the transmission system.
How to calculate the Backlash in a Double Worm Reduction Gearbox?
The backlash in a double worm reduction gearbox can be calculated using the following formula:
Backlash = 2 ¡Á (Module + Addendum)
Where:
- Module is the size of the gear tooth.
- Addendum is the height of the gear tooth above the pitch circle.
The formula is based on the fact that the worm gear has two teeth, and the clearance between these teeth corresponds to the backlash in the gearbox. The module and addendum values are typically specified by the manufacturer, and they can be used to determine the amount of backlash present in the gearbox.
The Significance of Backlash in a Double Worm Reduction Gearbox
Why is Backlash Important?
Backlash is an important parameter in gear design since it affects the accuracy and precision of the transmission system. Excessive backlash can cause vibrations, noise, and reduced precision in the system. On the other hand, no backlash can cause binding and premature wear of the gears.
How to Control Backlash?
The amount of backlash in a double worm reduction gearbox can be controlled by adjusting the position of the worm gears and the shims between the housing and the bearings. The adjustment of the shims allows for the precise positioning of the gears and the elimination of any excess clearance or binding.
