22個多型號試驗儀: 可進行磨耗， 耐擦性 ，耐洗性，靜態，動態摩擦試驗。
這種類型的設備的測試，是通過兩個表面在一定條件下相互摩擦，並確定由此產生的樣品的任何改變或表面之間的相互作用。
磨耗測試儀系列涵蓋了從最簡單的耐擦洗測試儀到最精密的能提供記錄測試運動阻力的設備。這類測力的方式能夠消除潛在的主觀人為因素帶來的影響。
·尺寸/重量：所有型號的基座就是一個0.25英吋厚的鋁板。所有型號都是16英吋寬，長度除了D5, D7, D8, D9 & D10 型是16英吋外其餘型號均為22英吋。淨重約40-50磅。
·為了防止受到意外液體洩漏的危險，所有功能元件都被安裝在測試平面的上方。
·所有功能組件都是厚實的經打磨的鋁材。
·驅動桿由1/16英吋不銹鋼焊接而成。
·線性摩擦由單一的驅動系統提供動力。
·驅動桿相對驅動架垂直可調。在最低位，它至少高於測試表面和玻璃板半英吋。這種相對低的位置減少了水平方向上的傾斜。
·驅動桿的每個齒上都有三個間距相同的孔。
摩擦力測試中有兩個基本因素：一個是樣品表面的光滑度狀況，但另一個因素也許更重要：樣品經過清洗或磨損試驗後，其表面狀況會發生明顯的變化。摩擦力的定義是：每當一個物體相對於另一個物體移動時，阻礙相當移動的力就稱之為摩擦力。
物體表面之間的摩擦特性：
樣品表面的特性
樣品表面所受到的壓力
兩種介質在一定範圍內的接觸面積
兩種介質在一定範圍內的運動速率
靜摩擦總是大於動摩擦
摩擦係數的定義是兩表面間的摩擦力和作用在其一表面上的垂直力之比值。摩擦係數範圍很廣。比如：抹油相對於金屬表面可以低至0.05，濕皮革相對於金屬大約是0.36，乾皮革相對於金屬大約是0.56。
為了測試任意兩種物體表面的摩擦，一個物體對於另一個物體必須有相對移動。作用於物體表面的壓力必須是固定的而且可知的。
這款線性磨耗儀完全適用於摩擦力的測試。為了滿足不同的測試要求，各種型號的儀器不僅可以用於樣品之間的測試，而且能夠直接用於樣品與儀器表面的摩擦測試。在可調速率的情況下，磨耗儀能夠在足夠低的速度運行，使動能和動量的因素可能被忽略。當作用於大多數物體表面時，建議採用每秒3-5英吋的速度。即使在機器面板上有力的顯示，記錄器仍被推薦用於測試中。在機器的測試過程中，記錄器表現出良好的精確度以及對摩擦阻力的及時反饋。
為了測試各種各樣的物體表面，我們提出在摩擦移動裝置和海綿盒子上附加的一定的重量。這兩者都是直接通過標準桿或機器驅動桿進行驅動。

Variable Speed Models (V)
|
|
The variable speed models have all of the features as the set speed models, plus variable speed. Each model has its own stroke length for its particular application. The stroke length is centered and shortened from both sides. Rate limits shown for all variable cycle rate (cyc/min) machines are factory set, but may be shifted for specific requirements. Instructions for this change are furnished with the unit.
Model D12V, when fitted with the test sample tray serves as a laboratory machine. This model has the base cutout feature. When the tray is removed, an extended drive fork may be added to pass through an opening in the base plate. This permits a test to be conducted directly on the surface on which the machine is placed. Stainless steel handles are attached to the ends of the housing to enhance portability for field use.

Variable Speed / Force Sensing (VF)
|
|
Models D7VF, D8VF, D9VF, D10VF, D12VF & D16VF
|
|
The variable speed / force sensing models are basically the same machines as the variable speed machines except a force transducer is added to the drive fork linkage. Output from the force transducer is displayed in large numbers on the front of the machine. The display registers resistance to motion of the fork to the one-tenth pound .
Model D12VF, when fitted with the test sample tray serves as a laboratory machine. This model has the base cutout feature. When the tray is removed, an extended drive fork may be added to pass through an opening in the base plate. This permits a test to be conducted directly on the surface on which the machine is placed. Stainless steel handles are attached to the ends of the housing to enhance portability for field use.
|
-
Built-In Force Measurement Feature: Resistance to motion (a measurement proportional to friction) is shown on control panel to the nearest 1/10 lb.
-
Variable Speed Control: Allows accelerated testing. Possibly called for in future specifications.
-
Designed for Present Day Washability Tests: Applicable to all 37 cycle rate test specifications.
-
ASTM Specifications: Applicable to Tests calling for use of 37 cycle rate Washability machines. FTMS, MIL, ISO and Other Specifications: Also applicable to tests calling for set rate, 37 cycle machines.

All Gardco designed and manufactured linear motion test equipment is described and specified in much greater detail than is called for in most of the many methods of test developed and promulgated by ASTM and other industrial and Federal agencies. Care has been taken in design and manufacture not only to overcome deficiencies in earlier equipment of this type but also to comply with the specifics as well as the intent of existing standards that call for the use of such equipment. The following is a list of standards and methods of test that call for this type of equipment.

Dimensions: The base is 0.25 inch thick aluminum plate. It is 16" deep and 16" long. One-half of the depth of the machine supports all functional mechanisms and their housing. The front half of the base provides the working surface or area for product testing. The base
is supported on one-half inch high feet to provide clearance for clamping test products at both ends and along the entire front edge of the base.
-
Net Weight: Approx. 40-50 pounds.
-
All functional elements are mounted above the normal level for product testing and therefore are not subject to damage by accidental liquid spills.
-
Heavy gage brushed aluminum houses all functional components with only the drive fork bracket extending forward to carry the drive fork over the test area. Access to the component area is by removal of only four screws from the lid of the housing. All controls and indicators
are mounted on the front surface of this housing. The housing is ten inches high and the PSI dial is viewed through the cut-out on top cover.
-
The drive fork is fabricated from 1/16" stainless steel. It is held in place by a bracket of the same material which is secured to linear bearings carried on accurately spaced parallel bars. Reciprocation of the drive fork assembly on the parallel bars is by a unique double chain and sprocket arrangement. There are no belts, cables, springs or other such mechanisms in the drive chain requiring service or maintenance.
-
Absolute linearity is obtained with the unique drive system. Acceleration and deceleration is sinusoidal providing for the smoothest possible change in direction at the end of each stroke.
-
The drive fork is adjustable vertically with respect to its drive bracket. In its lowermost position it is less than one-half inch above the test surface with the tray and glass plate in place. This relative low position minimizes the tendency of the carried surface to tilt in the
direction of travel. The fork can be raised in half inch steps, inverted and further raised to accommodate test specimens up to two and a half inches thick without losing close proximity to the test surface.
-
Design of the drive fork cradles accessories used in the test and permits them to simply be lifted free. There are, therefore, no rotational or other unbalancing forces imposed on such auxiliaries. They are “Free Floating” and self-leveling.
-
There are three equally spaced holes in each of the tines of the drive fork. A test auxiliary can be placed in either of the three pairs of holes to accommodate positioning of the test specimen. The spacing also permits simultaneous cradling of three brush boxes, two abrasion boats or two sponge boxes for multiple specimen testing.
-
The cycle counter is air operated and is energized through a switch from the drive linkage. The desired number of cycles is set by hand on push buttons on the face of the counter. There are five of these buttons for a maximum setting of 99,999. On start of operation, the counter cycles backwards from the preset value until it reaches zero and turns off the machine. The counter then may be manually reset to run the same number of cycles or the count may be changed.
-
Furnished with each machine is an instruction manual covering operation and maintenance. Included are schematic diagrams.
-
After every 100 hours of operation, the filter regulator lubricator should be purged of accumulated moisture. Add lubricant if needed. (See instruction manual)
-
After 2000 hours, or once a year, oil the drive chains. Brush oil directly on rollers. Use an artist brush. A few drops of oil should be placed on the parallel bars and at each end of the “tail” sprocket bearings.
