Gear engages come what is realized, and gear drive bearing capacity is big, and transmission accuracy is higher, can infinitely dock continuity, transmission speed can be very
Height, wherein the effect of driven gear is the direction of rotation for transmitting roller gear A, to make the direction of itself and roller gear B rotation
On the contrary, the purpose of the opposite gear in two direction of rotation of a motor driven is able to achieve, using this driving method, convenient for control
System, economizes on resources, the rotation of disk is to transmit power by frictional force, since round roller A or round roller B is applied with pressure to disk
Power, so producing frictional force, the mode of this transmitting power is energy saving, can also be in round roller A or circle in order to increase friction
Rubber ring is set on roller B, and increasing friction force while can prevent the damage that equipment is caused due to frictional force, this is practical
Bending knee mechanism in novel is arranged by the way of crank link mechanism, and crank link mechanism is connected by the low pair of several components
The plane mechanism of composition is connect, the forms of motion multiplicity of component, may be implemented the given characteristics of motion or fortune in planar linkage mechanism
Dynamic rail mark, bearing capacity is high, wear-resistant, and manufacture is easy, is easily obtained the higher accuracy of manufacture.Bending knee mechanism in seat be not
For carrying the gravity of sportsman, be for being made reference to sportsman's degree of bending the knee, as long as the hip of sportsman contact seat,
The process bent the knee as one adjusts the power resources of the seat in bending knee mechanism in traction mechanism, and traction mechanism uses motor A
As power, elongation or the retraction of telescopic rod are realized by rocking handle mode, rocking handle elongation or retraction are a lasting processes,
Continuously the lifting of seat can be adjusted, adjustment speed is controllable, the lifting that seat can be stable, and sportsman's difference may be implemented
The bending knee of degree is practiced.
