Operation
If the operating conditions are modified:
Note
Modifications to the effective load may cause the mass to strike hard against the
end position (load peaks).
• Repeat the setting of the YSR-C (
chapter “Commissioning”).
Hard knocking requires the following remedy:
• Reduce the impact speed, measure the cushioning length (s)
5 ( Fig. 3) as
a check (
Technical data Fig. 13).
Insufficient cushioning indicates a considerable loss of oil. In this case the
YSR-C must be replaced.
Maximizing the service life of the YSR-C:
If the shock absorber is not used to its full extent, there will be an increase in the
oil leakage.
• Make sure that the shock absorber is operated with an energy utilization of at
least 25% to max. 100%. The recommended range lies between 50 and 80%.
• Make sure that the YSR-C is utilized as follows:

• Take into account the fact that the viscosity of the hydraulic oil diminishes during
operation due to the friction heat which arises.
The shock absorber can therefore break through after a long period of operation.
At temperatures below 0 °C:
• Note that the resetting times of the YSR-C become longer (approx. 1 s).
Very low temperatures cause the viscosity of the hydraulic oil to increase.
6
Care and maintenance
• Check the oil loss on the YSR-C approximately every 2 million load changes. We
also recommend that you check the cushioning length (s) (
Fig. 3) of the YSR-C.
Otherwise the YSR-C does not require any maintenance.
7
Disassembly and repairs
• Reduce the amount of waste by using the materials in the YSR-C shock absorber
for other purposes (material recycling). The YSR-C is filled with hydraulic oil.
Due to the design, hydraulic oil cannot be refilled.

功能和应用
液压缓冲器 YSR-C 中装满了液压油。
当负载撞击缓冲器时,挤压油液流经节流阀进入另一腔体内,这个过程取决于
缓冲行程的大小; 撞击动能转化为热能。通过压缩弹簧的作用使活塞杆复位。
YSR-C
常用于承受惯性力。 它被设计用于吸收轴向作用力。
在许用负载范围内,YSR-C 通过缓冲垫也可作为止动挡块使用。
YSR-C
不能用于潮湿环境中。

产品使用条件
注意
操作不当会引发功能故障。
•
请确保始终遵守本章规定。
•
请将本操作说明中各项参数极限值与您使用场合的实际值
(例如:力、频率、质量、温度、速度 等)相比较。
只有遵守负载极限值才能使 YSR-C 按照相关的安全规程安全运行。
•
请注意产品应用地点的环境条件。
•
请注意遵守使用地点(例如:同业公会或所在国相关机构)的有关规定。
•
请勿对 YSR-C 的原装状态擅自进行任何改动。
3
安装
•
请选择适合您使用场合的安装方式。
钻孔
螺纹(通孔)
Fig. 14
当超过最大许用冲击力时:
•
除了液压缓冲器外,需额外使用止动挡块。
•
安装 YSR-C 时请注意以下几点:
–
负载应尽可能沿轴向撞向缓冲垫 4( Fig. 1),
(作用力方向的最大偏差为 5°, Fig. 2)。
–
外部止挡 7( Fig. 3)可防止 YSR-C 因惯性力过高而导致过载,
而且还有助于提高终端定位的精度( Fig. 3)。
•
按照所选的固定方式拧紧锁紧螺母 2( Fig. 1)。
拧紧时必须遵守下表中的紧固力矩:

调试
•
请注意下列力的允许值:
–
压入力(F2)( 技术参数 Fig. 18)
–
复位力(F1)( 技术参数 Fig. 18)
Fig. 16
•
压入力至少和(F2)相等,使液
压缓冲器能完全压入后面的终端位
置。对于前置的外部终端位置,
此值应相应地减小。
•
作用在活塞杆上的复位力最多
和(F1)相等,使液压缓冲器能
够完全复位(例如:活塞杆完全
伸出)。
•
先用较小的运行速度启动运动部件进行试运行。
试运行时:
•
将工作载荷逐步加速至所需运行速度。请根据具体的负载情况选定合适
的运行速度。正确的终端缓冲是:液压缓冲器的活塞杆到达终端位置
(止动挡块)时不会发生强烈撞击。
