Spiral bevel gears are commonly used for motion and power transfer between two intersecting axes. The teeth of the bevel gear are distributed on the surface of a cone whose tooth shape gradually decreases from the big end to the small end.
The spiral bevel gear is a kind of transmission device that can be driven stably and with low noise according to stable transmission ratio. It has different names in different regions, also called spiral bevel gear, curve-tooth bevel gear, gleason spiral bevel gear, circular-arc bevel gear, helical bevel gear, etc.
Rolling Mill Spiral Bevel Gears
The finishing mill/block mill is mainly composed of 10 stands, speed-increasing box, large base, drum gear coupling, water baffle, safety cover, guide and so on. The mill stand is composed of roll box and bevel gearbox with cantilever roll ring structure.
Bevel gearbox is composed of a box body, transmission shaft, spiral bevel gear pair, and synchronous gear pair. All gears are grinding gears with the hard tooth surface, tooth surface modification and accuracy of 5 grades, so as to ensure high speed and smooth operation.
Rolling Mill Spiral Bevel Gears Features
The spiral bevel gear transmission has high efficiency, stable transmission ratio, large arc overlap coefficient, high bearing capacity, smooth and smooth transmission, reliable operation, compact structure, energy saving, space saving, wear resistance, long service life and low noise.
Among various mechanical transmissions, the transmission efficiency of spiral bevel gears is the highest, which has great economic benefits for all kinds of transmissions, especially high-power transmissions; the transmission parts of transmission parts required for transmitting the same torque are the most space-saving, than belts, The space required for the chain drive is small;
The spiral bevel gear transmission ratio is permanently stable, and the gear ratio is stable. It is often the basic requirement for transmission performance in the transmission of various types of mechanical equipment;
The spiral bevel gear works reliably and has a long life.
