Abstract
The utility model relates to a device for realizing the joint swinging movement through a gear mechanism, which can be expanded to be applied to other swinging movement with small stress and compact structure requirements. The device comprises a motive power output device (such as an air cylinder, an oil cylinder and the like) (1), a rack (2), a middle gear (3), a middle shaft (4), a middle shaft support frame (5), an executing gear (6), an output shaft (7), an output shaft support frame (8), a swinging arm (9) and a fixed arm (10), wherein the swinging arm (9) is controlled by the motive power output device (1) to rotate in a certain range around the output shaft (7). The utility model converts the linear reciprocating movement of the motive power output device into the swinging movement of elbow parts and the like by adopting the gear mechanism, avoids insufficient stability of the output force caused by the dynamic change of pressure angles in the conventional connecting rod mechanism, ensures the constant output force, has convenient control and use, improves the efficiency, and has more compact structure.
Description
Technical field
This utility model belongs to the rehabilitation medical instrument field, particularly relates to the device of realization oscillating motions such as realizing elbow joint, knee joint, carpal joint, ankle joint in the rehabilitation machinery, also can expand as healthy people and athlete joint and take exercise, trains.
Background technology
In the universal machine engineering is used, straight reciprocating motion is output as oscillating traverse motion often adopts linkage to realize, for example the motion of excavator bucket realizes by bar linkage structure.The machinery that drives oscillating motions such as human elbow, knee joint, carpal joint, ankle joint in existing rehabilitation machinery, health and fitness facilities is also transplanted this linkage, because the pressure angle of linkage changes, cause effective power output non-constant, motion-affecting stationarity, and bigger to space requirement at the volley, structure is not compact.
Summary of the invention
This utility model adopts the output power straight reciprocating motion of device of gear mechanism to change the oscillating motion in joints such as ancon into, avoided that pressure angle changes the inconstant problem of effective power output that causes in the conventional linkage, the assurance pressure angle is constant, driving force is steady, improved efficient, more compact structure.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of device by joint oscillating motions such as gear mechanism realization ancons is provided, comprise PTO, tooth bar, idler gear, axis, bottom bracket, carry out gear, output shaft, the output shaft support, swing arm and fixed arm, described tooth bar is positioned in the groove of fixed arm and with PTO and is connected, described bottom bracket is fixed on the fixed arm front portion, described axis is supported on the bottom bracket, described idler gear is fixed on the axis and with tooth bar and meshes, described output shaft support is fixed on the fixed arm front end, described output shaft is supported on the output shaft support, described execution gear be symmetrically fixed on the output shaft two ends and with the engagement of the idler gear at axis two ends, being enclosed within on the output shaft of described swing arm.
Swing arm is rotated in 150 degree (buckling arm state) scopes at 0 degree (stretching hand with arm state) around output shaft by PTO control.
Beneficial effect
This utility model has been avoided in the conventional linkage pressure angle to change and has been caused the unsettled deficiency of effective power output, guarantees the constant power of output, is convenient to control and uses, and has improved efficient, more compact structure, and motor process takes up room little.Can be extended to stressed little, claimed structure is compact, control accuracy is higher, and other are realized in oscillating motions.

Fig. 1 this utility model elbow joint moves to the structural representation of extended position;
Fig. 2 this utility model elbow joint moves to the structural representation in centre position.
The specific embodiment
Below in conjunction with specific embodiment, further set forth this utility model.Should be understood that these embodiment only to be used to this utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications this utility model after the content of having read this utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in the figure, a kind of gear mechanism is realized the device of elbow joint oscillating motion, comprise that PTO (this example is a cylinder) 1 connects with tooth bar 2, the linear reciprocating motion of device (this example is a cylinder) 1 of outputing power passes to by tooth bar 2, idler gear 3 carries out gear 6, and drives output shaft 7 and back and forth rotate together.Being enclosed within on the output shaft 7 of swing arm 9, and swing synchronously with output shaft 7.Wherein, bottom bracket 5, output shaft support 8 all are fixed on the fixed arm 10; Axis 4 is supported on the bottom bracket 5; Output shaft 7 is supported on the output shaft support 8.Idler gear 3 connects with axis 4 and rotates synchronously, and execution gear 6 connects with output shaft 7 and rotates synchronously.
Claims (2)
1. device of realizing joint oscillating motion such as ancon by gear mechanism, comprise PTO (1), tooth bar (2), idler gear (3), axis (4), bottom bracket (5), carry out gear (6), output shaft (7), output shaft support (8), swing arm (9) and fixed arm (10), it is characterized in that: described tooth bar (2) is positioned in the groove of fixed arm (10) and with PTO (1) and is connected, described bottom bracket (5) is fixed on fixed arm (10) front portion, described axis (4) is supported on the bottom bracket (5), described idler gear (3) is fixed in axis (4) and goes up and mesh with tooth bar (2), described output shaft support (8) is fixed on fixed arm (10) front end, described output shaft (7) is supported on the output shaft support (8), described execution gear (6) be symmetrically fixed on output shaft (7) two ends and with the engagement of the idler gear (3) at axis (4) two ends, described swing arm (9) is enclosed within on the output shaft (7).
2. a kind of device by joint oscillating motions such as gear mechanism realization ancons according to claim 1, it is characterized in that: described swing arm (9) is spent in 150 degree scopes 0 and is rotated.
