Product introduction
This product is an all-metal high torque underwater steering gear.With large torque, small size, light weight and other significant advantages.
The operation process is maintenance-free and maintainable, and the underwater use depth can be up to 300 meters.The product torque output is stable, and the operation stability is higher when the virtual shaft is used, which effectively improves the load balance.It can be applied to all kinds of bionic machines, mechanical arms, underwater robots, etc.
The steering-gear adopts fully sealed design, the outer shell is made of aluminum alloy, the output shaft is made of high precision 316 stainless steel, the transmission precision is high, the corrosion resistance is high, the sealing is reliable, and it can be used in all kinds of water areas.Inside filled with pressure oil, with good heat dissipation performance.
The steering gear is controlled by PWM signal, with rated voltage of 12V and peak torque of 3N.M.Steering gear adopts all steel gear, strong bearing capacity, not easy to break teeth.The drive shaft is built with ceramic pressure bearing ball, which can withstand large axial load, making the underwater steering gear more diverse application scenarios.
The shell of the product has many threaded holes for installation, which can meet the requirements of efficient and convenient installation of various positions of the steering gear.Products can be installed "virtual axis", the use of more diverse scenarios.The virtual shaft is easy to install and disassemble. The virtual shaft is rotated by ball bearing, which rotates smoothly and smoothly (the virtual shaft bearing is a wearing part, which needs to be replaced regularly according to the actual use).
