Problems solved by technology
[0002] Large-scale rotary kilns, mills and other equipment are driven by large gears and small gears when rotating. When installing large gears and small gears, it is necessary to adjust the meshing head clearance of large gears and small gears according to the machining error of the tooth thickness of large gears and small gears. and backlash, the center distance between the large gear and the small gear in the existing structure is fixed, due to the machining error of the gear tooth thickness and the manufacturing error of the gear cover, the large and small gears cannot mesh correctly, which affects the transmission contact of the large and small gears accuracy, thereby affecting the service life of the gear

The invention discloses a center-adjustable gear cover sealing device. The center-adjustable gear cover sealing device comprises a gear cover, an assembling hole is formed in the gear cover, a plurality of fixing holes are formed in the outer side of the assembling hole, a sealing mechanism is arranged on the gear cover, the sealing mechanism comprises a sealing gasket, a sealing ring is arrangedon the outer side of the sealing gasket, an inner extending plate and an outer extending plate are arranged at the bottom of the sealing ring, a right-angle groove is formed in the inner side of an upper end opening of the sealing ring, a gland is arranged on the outer side of the sealing ring and presses the sealing ring on the inner extending plate at the bottom of the sealing ring, a pluralityof adjusting pads are arranged between the sealing ring and the gland, a gland cover plate is arranged on the outer side of the gland, a plurality of bolt penetrating holes corresponding to the fixingholes in the gear cover are evenly formed in the sealing gasket and the gland cover plate, U-shaped groove holes corresponding to the bolt penetrating holes are formed in the adjusting pads, the sealing ring and the gland, and the sealing mechanism is fixed to the outer side of the gear cover through bolts. According to the center-adjustable gear cover sealing device, the structure is simple, thedesign is reasonable, adjusting the center distance between the large gear and the small gear can be carried out, and the number of times of gear maintenance is reduced.
Description
technical field [0001] The invention relates to a gear cover sealing device, in particular to a centrally adjustable gear cover sealing device. Background technique [0002] Large-scale rotary kilns, mills and other equipment are driven by large gears and small gears when rotating. When installing large gears and small gears, it is necessary to adjust the meshing head clearance of large gears and small gears according to the machining error of the tooth thickness of large gears and small gears. and backlash, the center distance between the large gear and the small gear in the existing structure is fixed, due to the machining error of the gear tooth thickness and the manufacturing error of the gear cover, the large and small gears cannot mesh correctly, which affects the transmission contact of the large and small gears Accuracy, thus affecting the service life of the gear. Contents of the invention [0003] In order to solve the above problems, the present invention provi...
