Inquiry (采购产品): midi gear box Dear Mr. Gregory: I am building a little model that calls for a 0.41mm square drive gear box. The bottom part of it should have rounded edges even though the top could be square. The little drive gear's drive shaft measures 3/16s of an inch and is a hollow tube made of brass that extends through and out of the top of the casing. The two drive shafts, left and right, are made of the same material. The although the speed of of could be varied. I think that a speed of the unit at 1,2 to 1,400 rpm is suitable for this experiment, How- ever, id you have something that tops this that will be an asset. the little drive will have to turn approximately 3and1/2 pounds on eanch plastic vane type of plastic which weeight about 1/4 pounds for both. Both of these vanes rest on ball bearing for an easy start which is controlled by an adjustable or dimmer type output of current a 7 amp mini motor, I made a little drawing but my fax refuses to send clearly. Basicly you have practicaly all the info.
