Application Of Strain Wave Gear In Lower Limb Rehabilitation Robot

Generally speaking, the three-joint robot could stimulate the nerves and muscles of patients' lower limbs, promote the recovery of their functions, help them to establish a normal gait mode, and finally realize the patients' walking on the ground.

Product: 

Strain wave gear

J1 LHSG-32-120-C-III

J2 LHSG-25-100-C-III

J3 LHSG-20-100-C-III

Attention:

1) Due to personal safety, the safety factor of strain wave gear should be controlled at least 2.0;

2) The lower limb movement speed is not fast, the strain wave gear should choose a large speed ratio, the torque and stiffness will improve;

3) The grease couldn't be harmful to the human body.

Advantages:

1) Compact overall structure;

2) High torque density;

3) Large unipolar reduction ratio;

4) The running noise is small;

5) High precision, small backlash, no product clearance during operation

Future trend:

Since the beginning of the 21st century, the aging degree of our country has been deepening. There are 200 million old people, 85 million disabled people, and hundreds of millions of injured and chronic patients every year. There is a huge group and the demand for rehabilitation products is particularly wide. Therefore, the consumer market of the rehabilitation auxiliary industry has great potential and has become one of the fields favored by all parties.
