Abstract

PURPOSE:To control back lash and to use grease efficiently by providing the upper and lower frames of a gear box with elastic pressing members such as a rubber brought into pressure contact with the whole periphery of both side surfaces of a gear. CONSTITUTION:Pressing members 10 formed of an elastic material such as a rubber are disposed on symmetrical positions on respective inner surfaces of the upper frame 1a and the lower frame 1b forming the outer frame 1 of a bear box in such a manner as to surround each bearing portion 2 of bearings 3 supporting shafts 5, 5' of a gear 4. When the upper frame 1a and the lower frame 1b are coupled to form the gear box 1, a projecting part of the pressing member 10 is brought into pressure contact with both side surfaces of the gear 4 extending over the whole periphery with a fixed elasticity. The contact pressure force of the pressing member 10 is set not to obstruct the rotation of the gear 4.

Now, with the conventionally used gearboxes as described above, there are problems such as severe gear noise due to variations in one dimension, vibrations on both sides of the ear, and rattling due to backlash between the gears. Always supply grease to the tooth surface of the gear.For rounding, it is necessary to fill the entire space inside the outer frame of the gear with grease, but in this case it is actually used. Since the grease is filled with ~S, it often suffers from the disadvantage that it is very inefficient.
