Tower Crane gear mainly including 19/38/99 teeth gear, bevel gear, Tower Crane Sun Gear, and so on, which are the critical
parts of the tower crane reducer. 19 teeth gear and 38 teeth gear are
connected with two motor shaft repectively, which are connected with 99
teeth gear. The speed is reduced by the transmission of gears.
A bevel gear is a type of gear that has teeth cut on a conical surface. It is commonly used in tower cranes to transmit power between the vertical and horizontal shafts.

In a tower crane, the bevel gear is typically used to change the direction of rotation. The vertical shaft, which is connected to the motor, rotates vertically, while the horizontal shaft, which is connected to the crane's boom, rotates horizontally.
The bevel gear consists of two gears with intersecting axes. The teeth on the gears are cut at an angle, allowing them to mesh smoothly and transmit power. The gear ratio of the bevel gear determines the speed and torque of the rotation.
The bevel gear in a tower crane is designed to withstand heavy loads and provide efficient power transmission. It is usually made of high-strength steel to ensure durability and reliability in demanding crane operations.
Overall, the bevel gear plays a crucial role in the functioning of a tower crane by enabling the transfer of power and changing the direction of rotation between the vertical and horizontal shafts.
