滚珠丝杠与普通丝杠有什么区别

来源:http://www.jngongrun.com/ 日期:2022-09-21 发布人:admin

1、传动效率。

1. Transmission efficiency.
滚珠丝杠的传动效率大约是90~96%,梯形丝杠的传动效率大约是26~46%。即如果驱动同样大的负载,采用滚珠丝杠可以使用更小的驱动功率,例如更小功率的电机,既可降低成本,亦可降低能耗。
The transmission efficiency of ball screw is about 90~96%, and that of trapezoidal screw is about 26~46%. That is, if the same load is driven, the ball screw can use less driving power, such as a motor with smaller power, which can reduce both costs and energy consumption.
2、传动速度。
2. Transmission speed.
滚珠丝杠是滚动摩擦,梯形丝杠是滑动摩擦,工作时前者的温升远低于后者,因此可以承担高速传动任务。
The ball screw is rolling friction, and the trapezoidal screw is sliding friction. The temperature rise of the former is far lower than the latter when working, so it can undertake high-speed transmission tasks.
3、使用寿命。
3. Service life.
滚动摩擦的表面损伤比滑动摩擦的小很多,因此在清洁、润滑等条件符合时,滚珠丝杠的维持寿命比梯形丝杠高得多。
The surface damage of rolling friction is much smaller than that of sliding friction, so when the cleaning, lubrication and other conditions are met, the maintenance life of ball screw is much higher than that of trapezoidal screw.
4、自锁性。
4. Self locking.
自锁性一般与传动效率成反比,因此,滚珠丝杠几乎没有自锁性,而梯形丝杠具有一定的自锁性(视乎导程角的大小和工作面粗糙度)。
The self-locking property is generally inversely proportional to the transmission efficiency. Therefore, the ball screw has almost no self-locking property, while the trapezoidal lead screw has a certain self-locking property (depending on the lead angle and the roughness of the working surface).
5、经济性。
5. Economy.
从以前和目前的情况看,滚珠丝杠因其结构较梯形丝杠复杂,价格仍然比梯形丝杠高。不过,随着自动化设备的增多而产量变大,价格差异越来越小。
From the previous and current situation, the price of ball screw is still higher than that of trapezoidal screw due to its complex structure. However, with the increase of automation equipment, the output becomes larger and the price difference becomes smaller.
