Abstract
It the utility model is related to cam art, refer in particular to a kind of cam drive, including gear frame, the first curved rod, the second curved rod, first curved rod, the second curved rod are located at the two sides of cam respectively, first curved rod, one end of the second curved rod are all hinged with gear frame, first curved rod, the other end of the second curved rod are provided with roller bearing, connected between first curved rod, the second curved rod by elastic component, and elastic component forces the roller bearing to be close to the side of cam.After using the above scheme, noise can be effectively reduced, improves service life.
Description
Technical field
Cam art is the utility model is related to, refers in particular to a kind of cam drive.
Background technology
Cam mechanism is exactly the linear reciprocating motion that the rotary motion of cam is changed into driven member, typically utilizes cam
Chimb or cam in the groove that opens up realize the transmission of power, and kept away between cam and camshaft, it is necessary to leave gap
Unavoidable to produce abrasion and produce noise, therefore, the present inventor makes further research this, develops a kind of cam drive machine
Thus structure, this case produce.
Utility model content
The purpose of this utility model is to provide a kind of cam drive, can effectively reduce noise, and raising uses the longevity
Life.
To achieve these goals, the technical solution of the utility model is as follows：
A kind of cam drive, including gear frame, the first curved rod, the second curved rod, first arc connect
Bar, the second curved rod respectively be located at cam two sides, the first curved rod, the second curved rod one end all with gear frame
Hinged, the first curved rod, the other end of the second curved rod are provided with roller bearing, the first curved rod, the second curved rod it
Between connected by elastic component, and elastic component forces the roller bearing to be close to the side of cam.
Further, roller bearing is also equipped with the gear frame, the roller bearing of gear frame is located at the first curved rod, the second arc
Between connecting rod and the hinge joint of gear frame.
Further, first curved rod, the second curved rod are located at the outside of cam, and the elastic component is stretching bullet
Spring, the extension spring make the roller bearing of the first curved rod, the second curved rod be close to cam outer side edges by pulling force.
Further, first curved rod, the second curved rod are located at the inner side of cam, and the elastic component is compression bullet
Spring, the compression spring make the roller bearing of the first curved rod, the second curved rod be close to cam inner side edge by tensile force.
After using the above scheme, the utility model compared with prior art, has the following advantages：
The rotary motion of cam is set to become the reciprocal of gear frame by the transmission of the first curved rod, the second curved rod
Movement, and, the moment is all close to cam face, therefore will not produce gap, so that due to each roll shaft under the action of the spring
Unnecessary vibrations and abrasion are avoided, therefore improve the service life of mechanism, reduce noise.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model；
Label declaration
Gear frame 1, the first curved rod 2, the second curved rod 3, roller bearing 4, extension spring 5, cam 6.
Embodiment
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings.
As shown in the figure, by using exemplified by extension spring：A kind of cam drive, including gear frame 1, the first curved rod
2nd, the second curved rod 3, the first curved rod 2, the second curved rod 3 are located at the outside both sides of cam 6 respectively, and the first arc connects
Bar 2, one end of the second curved rod 3 are all hinged with gear frame 1, and the first curved rod 2, the other end of the second curved rod 3 are set
Roller bearing 4 is equipped with, roller bearing 4 is also equipped with gear frame 1, the roller bearing 4 of gear frame 1 is located at the first curved rod 2, the second curved rod
Between 3 and the hinge joint of gear frame 1, connected, and drawn by extension spring 5 between the first curved rod 2, the second curved rod 3
Stretching spring 5 forces the roller bearing 4 to be close to the side of cam 6.
When cam 6 is rotating under the action of rotation axis, due to the effect of extension spring 5, three roller bearings 4 are attached to convex always
The side of wheel 6, and due to the first curved rod 2, the second curved rod 3 radian of itself, them is not hampered cam 6
Rotate, and the first curved rod 2, the second curved rod 3 play the role of transmission in the reciprocating motion of gear frame 1, it would be desirable to past
After the component moved again is connected with gear frame 1, by the straight reciprocating motion (applicant for being converted into required component of cam 6
Original intention be high speed back and forth movement when solving embroidery machine sewing needed for sewing needle, but be also not only to use according to its principle
In the field).
According to above-mentioned principle, the first curved rod 2, the second curved rod 3 can also be arranged on the cam 6 with cavity
Inner side, and compression spring is used, compression spring makes the roller bearing 4 of the first curved rod 2, the second curved rod 3 tight by tensile force
6 inner side edge of cam is attached to, i.e., cam 6 plays the role of power transmission and path limits, and the first curved rod 2, the second arc
Connecting rod 3 plays the role of the transmission of power, is straight reciprocating motion by the translating rotation of cam 6, and eliminate cam 6 rotate when and
Running clearance between transferring member.
Above are only specific embodiment of the utility model, at the same in all the utility model it is involved as " it is upper and lower, left,
The words such as right, centre ", are only used as to refer to, not absolute limit, all changes that unsubstantiality is carried out using the utility model, should all
Fall into the category of infringing the protection scope of the present invention.
