Abstract
PURPOSE: To simplify the test job and to reduce the time, by pressing the gas with required pressure from the through-hole provided at the support frame to measure the watertightness for the coupling and joints of the respective support frames.
CONSTITUTION: The support frame 4 enclosing and supporting the support 1, drive source 2, control unit 12, variable speed gear 36, and limit switch unit 70, is only coupled airtightly with O ring, and the winding drum 55 is borne with the support 1 and the support frame 34 of the variable speed gear coupled airtightly with it, via the bearings 88, 89 having air ducts 88a, 89a, and the assembly is immersed in liquid. Next, the air under about 0.5 atm. is put in the body via the hose 87, air supply tube 36, through-female screws 32a, 30a from the air compressor to inspect the coupling section of coupling members, bonding section of the drum 55 and a pair of O rings 35, 59, and glands 7, 25, 73 for airtightness, through visual observation of bubble production. Thus, the test job can easily be made and the time can be decreased.
