What Is A Direct Drive Rotary Table?
The direct drive rotary table is basically a type of rotary table specifically designed for the constant operation that is multiple times more precise and agile than traditional face-ball gear or rack and pinion rotary table. This rotary table can be directly mounted on a shaft of a shaft, or it can use a gear-changing rack that allows you to change gears as you are spinning your wheel. A direct drive rotary table has the advantage over other rotary tables for a variety of reasons. First, it does not need any counterbalance springs because there is no pendulum that results in an unstable swinging shaft. Also, with the use of a direct-drive rotary table, the operator needs only one hand to control the table as opposed to all four when using traditional rotary tables.
High-speed indexing accuracy is another reason that makes this rotary table a better choice. Traditional rotary tables, by necessity, must slow down during operation. However, if a high-speed indexing accuracy is desired, this is not possible because of the nature of high-speed indexing. In this case, the best solution would be a rotary table that is able to maintain high-speed indexing accuracy at low speeds.
Rotary tables generally include torsion springs that help provide controlled torque to the tumbling buckets and sprockets. There are two different types of torsion springs on a rotary table: wound and linear torsion springs. Wound springs provide a consistent amount of torque throughout the swing operation whereas linear springs provide maximum torque near the beginning of the backswing and then gradually decrease torque as the club completes its downswing. While selecting between wound and linear torsion springs, it is important to consider the torque needed for the particular swing shot.
Direct drive tables can be a little more expensive than their winded counterparts. This is due to the material and design used in the construction. Typically, it is constructed from a combination of aluminum and fiberglass materials. These materials provide excellent rigidity at relatively low temperatures and, due to their lightweight structure, provide a good measure of stability. The design of a rotary table also contributes to its cost, with intricate cutting edges contributing to the increased cost.
A direct drive rotary table typically has features such as an adjustable timing window, variable valve lift, anti-stick clutch system, high-precision bearings, and sealed bearing housings. However, there are some direct drive rotary table options that feature anti-static clutch systems. These clutch systems eliminate the need for a motor because the clutch drives the rollers on the table itself. This eliminates any electrical components, which allows for longer, safer play and greater accuracy. Anti-static clutch systems also have the advantage of eliminating the need for mechanical springs, eliminating any potential shock to the user.
Most direct drive rotary tables have the ability to withstand extreme temperature ranges. Their construction also allows them to resist corrosion and remain looking good for many years. Many of these tables can be calibrated and fixed so they can be used for either scientific or industrial purposes. These rotary tables usually have a lifetime warranty.
