Direct Drive Rotary Table – The Benefits of Using One
Direct drive Rotary Table is basically a type of rotary table utilized for the constant operation that is many times more accurate and agile than conventional rack and pinion rotary table. This type of table is basically an axle system that is bolted to a shaft, with the presence of gear teeth, which rotates the axle while the teeth rotate on a fixed position. In the majority of these racks and pinion trotters, the shaft and the teeth are fixed in the center, whereas in some others they may have their rotation direction shifted to the left or right, so that the driving mechanism can be made to operate in any direction desired. Rotary table also comes with a rack and pinion adaptor, that allows tiling as well as attachment of materials to be mounted on the rotary shaft.
Some of the advantages associated with direct drive rotary tables are high speed performance, and excellent agility. In addition to that, there is also less wear and tear on the drive mechanism, as the teeth are always spinning at high speeds, and there is little or no slop involved. There are numerous advantages that are associated with direct drive rotary tables, and one of them is that it is easy to install and cost effective. Another important factor is that it offers the user with a high level of accuracy, and the user can increase the accuracy by varying the drive speed.
Rotary engines have an advantage over the others in that they have a zero backlash transmission. This means that the engine power is directly proportional to the torque produced. With the presence of zero-backlash transmission, there is a drastic reduction in the intake of air fuel and the emission of poisonous gasses, thereby saving both environment and money. Some of the features of a direct drive rotary table include:
Most of these units are driven by high-speed electric motors, which are extremely efficient and powerful. The torque and speed at which the rotors rotate are determined by the type of lubrication used. As most of these units run with ceramic bearings, there is no need to use oil for lubricating the moving parts. While the table does require high-quality lubricants for optimal performance, it is not necessary to use synthetic lubricants as they provide the same effect without the need for extra expense. Some of the other features that are available in most of these units include:
It is important to note that the shafts and connecting rods are usually of stainless steel to ensure that they do not rust easily. The table includes shafts of variable length, and each one has been designed with a different distance between the center of rotation and the outer edges. The closer they are to each other, the higher the performance level and the faster the reading will be. All Direct Drive Rotary Tables are known to have high-speed capability and high-torque. There are some models however, that including a gearbox to increase the torque even further.
In order to achieve the best performance from any of the direct drive tables on the market today, it is crucial to maintain them properly. The proper cleaning and lubrication of all moving parts are necessary to ensure that they are always functioning to their optimal capacity. For maximum results, it is recommended that you have a professional cleaner and lubricant provider perform this task. This is the only way to keep your rotary table performing at its highest level.
