What are the specifications of T screws? Where do they fit in?

T-screws are available in both imperial and metric sizes. The standard for the imperial system is acme, and the standard for the metric system is trapezoidal.

T-spindles are typically used in instrument-grade applications that require smooth, precise, clean and maintenance-free operation, and the nuts are typically made of internally lubricated polymer material. T-spindles are also used in laboratory and life science equipment, such as DNA sampling equipment, scanning equipment, and fluid handling equipment. Other applications include engraving, rapid prototyping, inspection, and data storage equipment.

According to the national standard GB and application examples, the ball screw (which has basically replaced the trapezoidal screw, commonly known as the screw) is used to convert the rotary motion into linear motion; Or the linear motion is converted into an actuator of rotary motion, and has high transmission efficiency, accurate positioning, etc.

When the ball screw is used as the active body, the nut will be converted into linear motion according to the lead of the corresponding specification with the rotation angle of the screw, and the passive workpiece can be connected by the nut seat and the nut to achieve the corresponding linear motion.

If fast response to control parameters is required, it is best to use a servo motion control card, which generally has DSP and high-speed logic processing circuits on it to achieve high-speed and high-precision motion control. Such as S-acceleration, multi-axis interpolation, etc.

Due to the continuous popularization of the use of ball screw pairs, the field of use continues to expand, and the requirements for ball screw pairs are also increasing, and the ball screw pairs of ordinary specifications are far from meeting the requirements of use, such as aerospace fields, small precision test devices, electronic instruments and semiconductor devices, etc., which basically need a miniature ball screw pair with a nominal diameter of d0 12mm and a lead pH = mm. NSK has developed the world's smallest lead miniature ball screw pair with a nominal diameter of D0=4mm and a lead pH=. 15 Straight lead screws have?

1510 ball screws, etc.

Semiconductor plug-in devices, small robots, etc., require miniature ball screw pairs with large lead to meet the requirements of high-speed drive. With the development of mechanical products in the direction of high speed, high efficiency and automation, industrial robots, CNC forging machinery, machining centers and mechatronics automatic machinery, etc., their feed drive speed continues to increase, and the emergence of large lead ball screw pairs meets the requirements of high speed. The Japanese company NSK has developed a nominal diameter lead of:

15mm 40mm, 16mm 50mm, 20mm 60mm, 25mm 80mm ultra-high lead ball screw pair, fast feed speed up to 180m Walking diameter recommendation: 2005 ball screw etc!

Miniature ball screw pair refers to a ball screw pair with a nominal diameter of d0 12mm. For the ball screw pair with a lead pH of 3mm, it is called a miniature small lead ball screw pair, and a ball screw pair with a spiral rise angle of 9° is called a micro large lead ball screw pair.

Large lead ball screw pair refers to the ball screw pair with a nominal diameter of d0 16mm, a spiral rise angle of 17° 9° or a lead of d0 ph d0, and a helical rise angle of 17° is called a super large lead ball screw pair. Heavy-duty ball screw pair refers to a ball screw pair with a nominal diameter of d0 125mm. Go to Shanghai Manlu and ask.

1.What is the screw size chart?

The screw specification and size table is an important information in mechanical design, which records in detail the key parameters such as the specification size, pitch, lead, length, and quality of the screw rod, helping mechanical engineers to select the appropriate screw rod when designing.

2.The influence of screw specifications on mechanical design.

The specifications of the screw rod have an important impact on the mechanical design, and different specifications will affect the accuracy, speed, force multiplier and so on of the machine. For example, a screw with a small pitch can improve the accuracy of the machine, but the speed is slower; Spindles with a larger pitch are faster, but less accurate. Therefore, it is crucial to select the appropriate spindle size in the mechanical design.

3.How to choose the screw specification?

When selecting a screw size, factors such as the accuracy, speed, load, and working environment required by the machine need to be considered. In general, it is necessary to meet the precision requirements, speed requirements, and load-bearing load requirements of the mechanical design of the full touch wide foot. In addition, it is also necessary to consider comprehensive factors such as the quality of the screw rod, the best quality, and the ease of installation, so as to make the best choice.

4.The importance of the screw size chart.

The screw specification and size table is an indispensable information in mechanical design, which records the specifications and dimensions of various screw rods, and provides a basis and reference for mechanical design. In mechanical design, the selection of suitable screw rod can improve the efficiency and stability of mechanical operation, reduce maintenance costs and use costs.

5.Classification of screw rod specifications and size charts.

The screw rod specification size table can be classified according to the different specifications of the screw rod, such as straight screw, angle screw, hybrid screw, etc. Different types of screw size charts will record different parameters such as lead, pitch, length, diameter, etc. Depending on the required mechanical specifications, the corresponding screw type and size chart can be selected.

6.How to check the screw size chart?

In mechanical design, it is very important to consult the screw rod specification and size table, which can provide a basis and reference for mechanical design. When checking, you need to understand the required mechanical specifications and the type of screw rod, and then look for the corresponding screw specification size chart.

The latest version of the screw specification and size table will record more detailed and complete screw information, providing more accurate and efficient material selection solutions for machine manufacturers.

8.Summary.

The screw size chart has an important influence and role in mechanical design, it provides a wealth of screw information and reference materials to help mechanical engineers choose the right screw specification. When choosing, it is necessary to fully consider the mechanical design requirements, screw type, quality, and other comprehensive factors to make the best choice.

1. According to its structural type, it can be divided into:

Type 1 - the screw rod rotates and moves axially at the same time.

Type 2 - the screw rod is rotated, and the nut on the screw rod moves axially.

2. According to its assembly type, it can be divided into:

Type A – The screw or nut moves upwards.

Type B – The screw or nut moves downward.
