Hydraulic Shock Absorbers As mechanical parts of operating machinery such as automated assembling systems, conveyors and safty devices for machine tools strive to increase operation speed and precision, more often the results shows increased noise, vibration as well damage to the machinery. To avoid decreasing safty and machine reliability typical products are used include rubber bumper, springs, cylinder cushion and industrial shock absorber. The adventage of using KOBA shock absorber : Longer life cycle of machinery due to reduction of shock and vibration. Higher operating speed - shock...

Orifices Feature Single Orifice Single Orifice Type - called Dashpot structure offers progressive damping characteristic. Orifice mass Multiple Orifices ■Adjustable Pressure oil flow controled through several orifice offer linear deceleration by providing a constant shock force over the entire stroke - most efficiency. Multiple Orifices Picture shows characteristic of damping (A1 high velocity - low propelling force : B1 low velocity - high propelling force) Multiple Orifices mass Stroke

This is one kind of the non adjustable Multiple orifice types. This type has quick response and good efficiency for short stroke because the changing of orifice area is continuous. Short stroke means under 25mm (but KMS14-20 is not including in this type) Force Metering Orifice Shock Absorber Selection 1. Identification of following parameters : 1.1 Load weight (kg) 2. Steps to select the right Model 2.1 Check the conditions ■ Check how the object will hit the Shock Absorber : Horizontal motion, Vertical motion, Inclined motion, or rotary motion. With or without Propelling force ■ Check the...

Hydraulic Shock Absorbers 2.7 Check the total Energy per hour ET C. ■ Find the Total Energy per hour with cycle per hour and Total Energy per cycle and check it within the range of selected model's in Engineering Data in Catalog. ET C ≥ ET x C 2.8 Check the Effective Weight (We) ■ In the case of collision with Propelling Force, Check the Effective Weight (We). Especially you should check it in the case of low velocity (under 0.3m/s), We = ( 2 x ET ) / V2 [ The Calculated value of We should be within the range decsribed in Engineering Data in catalog.] In the case of collision without...
