Thomson絲杠產品工程師Jeff Johnson指出,滾珠絲杠和梯形絲杠有時可以用在同一個應用中。一般情況下,滾珠絲杠用在大負載或要求長壽命的工業應用中,而梯形絲杠則更適合小型、 低負載應用。然而梯形絲杠的定制性很強,可以快速更換導程、尺寸和螺母配置。選擇絲杠技術時,成本通常不是首要考慮因素。觀看這段視頻,您將了解滾珠絲杠 和梯形絲杠的差別。

Dynamic Load (Ball Screws)
Dynamic load rating is the maximum load which a ball bearing screw assembly can maintain for 1.0 million inches of travel (Inch Series) or 1.0 million revolutions (Metric Series).
Design Load (Lead Screws and Glide Screws?)
Maximum load at which a lead screw assembly should be operated. Not applicable for life calculations.
The nominal outside diameter of the screw shaft for a screw only. For a nut it is the nominal outside diameter of the mating screw.
The axial distance a nut travels from one revolution.
The direction of threads on a shaft or in a nut. Left hand means that the nut will move away if rotated counterclockwise. Right hand means the nut will move away if rotated clockwise.
The axial free motion between the nut and screw is called backlash. An Ant-backlash nut is designed to reduce or eliminate this movement.
Lead Screw
The lead screw assembly converts rotary motion to linear motion. The lead nut slides over the thread of the screw. Thomson lead screws excel in applications which require the “just right” solution.
Ball Screw
The ball screw assembly converts rotary motion to linear motion with recirculating ball bearings. Ball screws have a very low friction coefficient and is typically greater than 90% efficient.
Glide Screw?
Part linear bearing, part lead screw, the Glide Screw? from Thomson combines the best features of these products into an easy to install, one-part solution.
