Helical Bevel GearsElevatorAlso known as bevel gearsElevatorUmbrella GearSpiral HoistIt and the worm screwElevatorSame, a fundamental lifting component, but unlike worm gearsElevatorThe difference lies in its internal structure, which is a bevel gear arrangement rather than a worm gear and worm arrangement. Compared to the worm gear and worm structure, the bevel gear arrangement boasts higher efficiency, longer lifespan, and ease of adjusting the speed ratio. It also has the advantages of being compact, lightweight, noiseless, and easy to install. It can perform functions such as lifting, lowering, propelling, and flipping objects. However, its maximum input speed is 500 r/min, which is faster than the worm gear and worm structure.Lift ElevatorThe price is low, but its speed can reach 2.7m/min, and it can also be self-locking.

Helical GearLift ElevatorThe structural forms are divided into two types: one where the screw performs both rotational and axial movement, and another where the screw rotates while the nut moves axially. The assembly types include screws or nuts moving upwards, as well as screws and nuts moving downwards. The head is available in cylindrical, flanged, threaded, and flat-head designs. Protective tubes and anti-rotation devices can be added.

Note: Be aware of the helical bevel gears.ElevatorAt loads below the rated load, the allowable height increase is permitted. Moreover, the allowable torque, power, and speed vary with different loads, and the maximum power at different startup duration rates also differs. For those with bidirectional sleeves,ElevatorThe screw shaft allows for partial lateral forces. Gear, sprocket, and belt pulley attachments are permitted.
