Trapezoidal Spindles. Buy online at the best price
DIN-103 trapezoidal spindles are a type of transmission mechanism from rotary motion to linear motion. It consists of a threaded shaft with a trapezoidal shape and a nut that slides on the thread of the spindle. As the spindle rotates, the nut moves along the spindle axis, converting rotary motion into linear motion.
Trapezoidal thread features include:
- Trapezoidal shape: The shape of the trapezoidal thread resembles a trapezoid with a wider base and a narrower top. This shape provides a lower thread angle and greater crest width, resulting in greater force transmission efficiency and rigidity.
- Pitch angle: The pitch angle of trapezoidal thread is usually 30 degrees. This pitch angle accommodates linear loads, resulting in increased load capacity and wear resistance.
- Wider crest: The crest of a trapezoidal thread is wider than that of a square or round thread. This allows for greater load distribution and greater resistance to wear and fatigue.
- Continuous thread: The trapezoidal thread is a continuous thread thread, meaning it does not have flat sections like square or rectangular type threads. This allows greater efficiency in force transmission and greater system rigidity. They have a threaded entry.
Trapezoidal spindles are commonly used in machine tools such as lathes and milling machines, gate lifters as well as other industrial equipment. They are an efficient way to convert motor rotation into linear motion to move workpieces or tools in a straight line, such as the spindle feed of a drilling machine.
The trapezoidal shape of the spindle thread provides greater efficiency in force transmission and greater rigidity than threads with round or square shapes. Additionally, the geometry of the screw and nut allows for greater control over the precision of the linear movement and the load that can be supported. This precision load is 100 It has a hardness of 250 HB. They are available in threads from TR-10 to TR-90 and it is also possible to supply right-hand threads and left-hand threads. The trapezoidal spindles are made of carbon steel EN 180083-2 IC45 – 1053 and also in quality INOX 304 A2 AISI-304 and INOX-316 A4 AISI-316 steel.
Trapezoidal spindle nuts are essential components in linear motion transmission systems. These nuts are specifically designed to fit and slide over the trapezoidal thread of the spindle and convert the rotary motion of the spindle into linear motion. The tolerance of these nuts is 7H.
There are various shapes of nuts for each need, such as cylindrical nuts, hexagonal nuts, nuts with a flange that has built-in holes for fixing.
Likewise, we have several types of materials for these nuts, Steel, Stainless steel, bronze and plastic and even combinations between these that cover all the needs of the market.
