Application of Direct Drive Motor in Gear Measurement Center
In the machining and testing equipment, each motion axis has a variety of transmission modes, such as the worm gear of the rotating shaft, the screw drive of the linear axis, the synchronous belt drive and so on. The disadvantages of the transmission modes of these motors and transmission components are low rigidity, high efficiency loss, and high noise. Nowadays, more and more mechanical equipments begin to adopt the direct-coupled driving method of direct-drive torque motor and linear motor, which has the characteristics of high rigidity, fast response speed and high control precision.
First, the development of gear measurement center
The gear measuring center is a high-precision, high-automatic testing equipment used by gear production and use enterprises for the accuracy index detection of gears and gears. Its normal structure is composed of a high-precision rotating spindle and three high-precision linear axes. In the past, linear axes were mostly driven by a rotating servo motor with a lead screw or a timing belt. For the large-gear measurement center, the spindle drive is also high. Precision worm gear mechanism. The disadvantages of these traditional transmission methods are low rigidity of the system, slow dynamic response when closed-loop control is adopted, the motion accuracy is greatly affected by the worm gear pair and the lead screw, high noise during high-speed motion, low system stability, and increased measurement uncertainty. Sex. With the development of direct drive torque motors and linear motors, the technology of direct drive torque motors and linear motors in gear measurement centers is becoming more and more mature. These applications using new motor technology drive methods not only reduce motion noise, but also reduce losses. The important thing is that the rigidity of the system is greatly improved, the response speed of the control system is improved, the measurement speed and the stability of the system are improved, and the measurement uncertainty is reduced.
Second, the application of Kollmorgen motor in L series gear measurement
Comparing the performance and price of different brands of motors on the market, based on Kollmorgen's market popularity and cost-effective products, Haliang Group Precision Measuring Instrument Co., Ltd. selected Kollmorgen's KBM for L series gear measurement center products. The frameless direct drive torque motor series and the ICD linear motor series are equipped with an AKD driver as an application, and have achieved good results.
