Основные технические параметры
Диапазон технических характеристик: стандартный диаметр вала составляет от Φ12 мм до Φ100 мм, а вывод — от 4 мм до 20 мм, что позволяет удовлетворить самые разные потребности: от точной настройки до быстрого перемещения.
Класс точности: стандартная точность обычно составляет C7, что является экономичным уровнем точности, достаточным для большинства требований к оборудованию автоматизации.
Конструкция гайки: обычная конструкция с внутренней циркуляцией, обеспечивающая более компактную конструкцию и меньший уровень шума при работе. В некоторых моделях для повышения производительности используется гайка в форме талии или металлический обратный клапан.
Дополнительные конфигурации: поддерживается индивидуальная обработка концевого эффектора (например, фрезерование шпоночных пазов, сверление), и его можно сочетать со стандартными опорными основаниями (серии BK/BF, FK/FF и т. д.) для обеспечения комплексных решений.

Ball Screw Assembly Workshop
One ball screw shaft matches one ball screw nut. Because each ball screw shaft has a very tiny different tolerance. There are dozens of different ball sizes for different screw shaft. Our ball screw shaft and nut can be interchanged with the Taiwan TBI ball screw shaft and nut very well. |

1-1-1 Lead/Travel Accuracy
According to the standard of JIS,we classified our lead accuracy through E,e,e3oo and e2m four main regulations.As figure 1.1.1~1.1.3 shown in below, all the definition and tolerance are specified.To test the accumulated travel deviations for grade C7 and C10, the tolerance wll be chosen in random 30omm of useful length and evaluated if it is qualified with the e300 table of 1.1.3.

| Travel Compensation |
T |
Travel compensation is the deduction between specified and nominal travel in the useful travel. A slightly smaller value compared with nominal travel is often selected by customer, to compensate for an expected elongation caused by temperature rise or external load. Therefore"T "” is usually a negative value. Note:if no compensation is needed,specified travel is the same as nominal travel. |
Table 1.1.2 |
| Actual Travel |
|
Actual travel is the axial displacement of the nut relative to the screw shaft. |
|
| Mean Travel |
|
Mean travelis the linear best fit line of actual. This could be obtained by the leastsquares method. This line represents the tendency of actual travel. |
|
| Mean Travel Deviation |
E |
Mean travel deviation is the deduction between mean travel and specified travel within travel length. |
|
| Travel Variations |
e

 |
Travel variations is the coverage of 2 lines drawn parallel to the mean travel. Maximum width of variation within the travel length. Actual width of variation for the length of 300mm taken anywhere within the travel length. Wobble error, actual width of variation for one revolution (2πt radian) |

Excessive preload increases the friction torque and generates heat which wll reduce the life expectancy. However, insufficient preload will reduce stifness and increase the possibility of lost motion. WANGONG recommends that the preload applied on CNC machine tools should not heavier than 8% of the dynamic load; 5% for industrial automation X-Y table.

1-1-3 Definition of Mounting Accuracy and Tolerance on Ball Screw
The main items of the mounting accuracy of ball screw are listed in below.
(1) Periphery run-out of the supporting part of the screw shaft to the screw groove.
(2) Concentricity of a mounting portion of the shaft to the adjacent ground portion of the screw shaft.
(3) Perpendicularity of the shoulders to the adjacent ground portion of tha screw shaft.
(4) Perpendicularity of the nut flange to the axis of the screw shaft.
(5) Concentricity of the ball nut diameter to the screw groove.
(6) Parallelism of the mounting surface of a ball nut to the screw groove.
(7) Total run-out of the screw shaft to the axis of the screw shaft.
All WANGONG ball screws are manufactured, inspected and guaranteed to be within specifications.

1-1-4 Preload Torque
As figure 1.1.3 shown in below, it specified allthe type of preload torque generated by rotating a preloaded ball screw.

Fig 1.1.3 Descriptions of preload torque
Glossary
1. Preload
To generate the inner force inside the ball screw to decrease the
clearance and increase the rigidity, a set of one gage ( approximately 2μ) larger steel balls is filled inside the nut or two nuts which are executing mutual displacement in axial direction.
2. Preload dynamic torque
The dynamic torque required for continuously rotating the screws shaft or the nuts under unload condition and the preload has applied to the ballscrews.
3. Reference torque
The targeted preload dynamic torque Fig 1.1.3-(1)
4. Torque variation values
The variation values of the targeted preload torque variation rates are specified.Take a positive or negative value relative to the reference torque.
5. Torque variation rate
The variation ratio of reference torque.
6. Actual torque
The actual measured preload dynamic torque of the ball screws.
7. Average actual torque
The arithmetic average of the maximal and minimal actual
torque values measured when the nuts are doing reciprocating
movements.
8. Actual torque variation values
After the nut doing reciprocating movements on the effective
length of the thread, the biggest variation tested will be the actual
torque variation value, which is covered between the positive and negative minimum value relative to the actual torque.
9. Actual torque variation rate
The rate of actual torque variation values in relation of the average
actual torque.
