Drive Mechanism and Type

|
|
| ||
| Drive Mechanism | |||
| Your choices are... | |||
| Ball Screw | A ball screw uses recirculating steel balls, which roll between the screw and the ball nut. Rolled screws are cold rolled from a blank. Typically, this produces a screw with a 0.004 inch per foot accuracy. Ground screws are made on a grinding wheel with an Acme form. Typically, this produces a screw with 0.0005 inch per foot lead accuracy. | ||
| Lead / Acme Screw | A typical lead screw has a "V" thread. It is relatively easy to machine and roll form. A “V” thread has an angle of 60° between opposing faces. Acme screws use plastic or bronze solid nut. An Acme screw is a specific type of lead screw. An Acme thread has an angle of 29° between opposing faces. Acme screws provide motion through direct sliding friction between nut and lead screw. Rolled screws are cold rolled from a blank. Typically, this produces a screw with a 0.004 inch per foot accuracy. Ground screws are made on a grinding wheel. Typically, this produces a screw with .0005 inch per foot lead accuracy. | ||
| Belt, Band, or Cable and Pulleys | The linear motion is produced by a timing belt, band, or cable and pulley system. | ||
| Micrometer | A micrometer produces the linear motion. | ||
| Other | Other unlisted, specialized, or proprietary drive mechanism. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
| |||
| Drive Type: | |||
| Your choices are... | |||
| None | The unit does not contain an integral drive. | ||
| Handwheel / Crank | The unit does not contain an integral motor drive. It is a handwheel or crank handle drive. | ||
| AC Motor | The unit contains an integral AC motor. AC motors include single / multiphase, universal, servo, induction, synchronous, and gearmotor types. The magnetic field, generated by AC motors, is produced by an electromagnet powered by the same AC voltage as the motor coil. | ||
| Brushless Servo | The unit contains an integral brushless servomotor. Servomotors are generally small and powerful for their size, and easy to control. Brushless motors are a typical type of DC servomotor. | ||
| DC Servo | The unit contains an integral DC servomotor. Servomotors are generally small and powerful for their size, and easy to control. | ||
| Linear Motor (Direct Drive) | The unit contains an integral linear motor. A linear motor generates force only in the direction of travel. | ||
| Stepper Motor | The unit contains an integral stepper motor. A stepper motor uses a magnetic field to move a rotor in small angular steps or fractions of steps. | ||
| Other | Other unlisted, specialized, or proprietary drive type. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
| |||
| Lead | Lead = Inches per 1 revolution of screw. Note: Lead Screw Pitch = 1/Lead or number of turns per inch of linear travel. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||

|
| ||
| Your choices are... | |||
| Brake / Lock | A brake assembly for slowing or stopping the linear motion, or a lock for maintaining the carriage position. | ||
| Clutch | A clutch assembly for connection or disconnection of the drive mechanism. | ||
| Brake / Clutch Combination | A combination brake / clutch assembly for slowing or stopping the linear motion (brake) and connection or disconnection of the drive mechanism (clutch). | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
