Crane Gear Coupling for overhead crane and gantry crane

Diameter: Φ120mm~Φ1500mm



The gear coupling is used to connect mechanical parts to transmit torque. It consists of two parts, the driving shaft and the driven shaft. It can connect motors, reducers, wheel sets, etc. for the overhead crane, gantry crane, etc. In high-speed and heavy-duty power transmission, the couplings have the functions of buffering, damping and improving the dynamic performance of the shafting.

Crane Gearbox F Series for crane, hoist

 Model: FA37~FA157

 

F series crane gearbox

 

Introduction:

F series crane gearbox is for the lifting and traveling mechanism of overhead crane and gantry crane, which has the characteristics of small size and large transmission torque. It is designed and manufactured on the basis of the modular combination system, there are many motor combinations, installation forms and structural schemes, and the transmission ratio is finely graded to meet different operating conditions and realize the integration of motors. The F series gearbox adopts the modular design principle of unit structure, which greatly reduces the number of parts and inventory, and also greatly shortens the delivery cycle. High-rigidity cast iron box with ribs; hard-toothed surface gears are made of high-quality alloy steel, the surface is carburized and quenched and hardened, the teeth are finely machined, stable transmission, less noise, large bearing capacity, workable in low temperature, and long service life.

 

Structural Features:

1. Helical tooth structure;

2. Compact structure and space saving;

3. High bearing capacity, low vibration, low noise, low energy consumption, energy saving and high efficiency.
