INCH-POUND A-A-52160A 18 January 2011 SUPERSEDING A-A-52160 25 August 1990 COMMERCIAL ITEM DESCRIPTION INDUSTRIAL V-BELTS (MULTIPLE DRIVE) The General Services Administration has authorized the use of this commercial item descriptio
3、n for all federal agencies. 1. SCOPE. This commercial item description (CID) covers the general requirements for V-type industrial drive belts. V-type industrial drive belts covered by this CID are intended for commercial/industrial applications. 2. CLASSIFICATION/PART IDENTIFICATION NUMBER (PIN). T
4、his CID uses a classification system which is included in the PIN as shown in the following example (see 7.1). TABLE I. Cross section size. A-A-52160 / 3 B 90 R Oil resistant CID Belt length (table IV) Number Belt width (table I) Number of belts in set Example PIN denotes A-A-52160 belt 0.66 inches
5、wide, standard datum length of 91.8 inches with oil resistant capabilities. Three belts in a set. 3. SALIENT CHARACTERISTICS. 3.1 Material and dimensions. The belt dimensions, tolerances, and method of measurement shall be in accordance with RMA IP-20. Belt cord shall be pre-stretched and impregnate
6、d with a rubber compound. The belts shall be static conductive type in accordance with RMA IP-3-3. The belts shall not crack break or require more torque to start or continue rotation than that specified in table lI when tested as follows. 3.2 Functional test. Place the belt in an unrestrained horiz
7、ontal position so that, it does not contact the side walls of the test chamber. Maintain the temperature of the oven at 150F plus or minus 2F for 12 hours. At the end of the 12 hour period, remove the belt from the oven and allow the belt to cool for 30 minutes at room temperature. Install the belt

9、I. Lock the tension pulley location, remove the tension weights from the belts, then place the assembly in a cold chamber at a temperature of minus 40F plus or minus 2F for 12 hours. At the end of the 12 hour period while the assemble is still at minus 40F plus or minus 2F rotate the pulley until th
10、e belt has been rotated not less than two complete revolutions. Measure and record the torque required to start and the torque required to continue rotation, then remove the belt from the assembly and examine for evidence of cracking. Any evidence of cracking, or torque necessary to start or continu
11、e rotation in excess of the amount specified in table lI shall constitute failure of this test. TABLE II. Torque.

The be
13、lts in A(13c), B(16c) and C(22c) cross-sections shall be representative of D(32c) cross-section for the temperature test provided they are manufactured with the same basic compounds and tensile members. 3.4 Oil resistant belts. For oil resistant belts the thickness shall increase no more than 20%, n
14、or decrease more than 1% when immersed in IRM 901 and IRM 902 as cited in ASTM D471. The test shall consist of two 3 inch (7.6mm) long sections of belt being immersed in 150F (70 C) oil bath for 22 hours. The average of three measurements, the center point and inch (13mm) from each end, shall consti
15、tute the thickness. When required the age of the belts shall not be more than 12 months old from the time of manufacture to the date of acceptance by the government. 3.5 Marking. The V-belt supplied to this CID shall be marked with the manufacturers (MFRs) standard commercial PIN. The PIN marked on
16、the unit pack shall be the CID PIN. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-A-A-52160A 3 TABLE lV. Belt length.
