The invention discloses a double-bearing over-positioning device, which comprises a shaft, a bearing and a sliding chute, wherein the shaft and the bearing are fixedly connected together; the shaft is connected with the power output end of an executing piece, and performs translational motion along a direction vertical to the axis of the shaft; the sliding chute consists of a strip-shaped top plate, a strip-shaped bottom plate and a strip-shaped side plate which is connected with the strip-shaped top plate and the strip-shaped bottom plate; the bearing consists of an inner bearing and an outer bearing which are arranged in parallel; the inner bearing and the outer bearing are only contacted with the working surfaces of the strip-shaped top plate and the strip-shaped bottom plate respectively. According to the double-bearing over-positioning device, the gap between the bearing and the sliding chute is eliminated, the possibility of circumferential rotation of the shaft is lowered, the positioning accuracy is increased, and wear caused by interference between the upper and lower contact surfaces of the bearing and the sliding chute is avoided; the double-bearing over-positioning device can be widely applied to transmission devices.
Description
Technical field
The present invention relates to transmission device, particularly relate to a kind of duplex bearing and cross positioning device.
Background technique
Due to the error of manufacturing and assembling, likely produce circumferential rotation during along the reciprocating axle operation perpendicular to its axial direction.For this reason, this axle on wrapping machine was equipped with positioning means more---and be the bearing slided on chute that has been connected on axle, can effectively avoid this rotation.Compare, crossing positioning means has following advantage:
1, can improve transmission accuracy, strengthen transmission stability;
2, prevent that the actuator on axle from producing the phase mutual interference with the miscellaneous part kinematic pair accumulation of error;
Vibration and noise while 3, reducing the wrapping machine high speed operation.
But the existing positioning means of crossing has also brought following deficiency:
While 1, just having brought into use, due to the surface of contact gapless of bearing and chute strip top board and strip base plate, bearing and chute surface of contact can produce interference, can't accomplish pure rolling, with the chute surface of contact be sliding friction, thereby unstable wear;
2, after using a period of time, owing to running out bearing, with the chute surface of contact, start to occur gap, axle still can produce slight circumferential rotation, affects the further raising of transmission accuracy.
Summary of the invention
The objective of the invention is in order to overcome the deficiency of above-mentioned background technology, provide a kind of duplex bearing for the reciprocal translation along perpendicular to its axial direction to cross positioning device, not only eliminated the gap between bearing and chute, reduce axle and produced the possibility of circumferentially rotating, improve positioning precision, and avoided the wearing and tearing that cause due to interference that bearing and the upper and lower surface of contact of chute produce.
A kind of duplex bearing provided by the invention is crossed positioning device, comprise the axle and the bearing that are fixed together, and chute, described axle is connected with the clutch end of actuator and along perpendicular to the axle axial direction, doing reciprocal translation, described chute is comprised of the strip side plate of strip top board, strip base plate and connection strip top board and strip base plate, described bearing consists of the inner bearing be arranged side by side and outer bearing, and described inner bearing is only limited to respectively with the strip top board in chute and contacts with the working surface of strip base plate with outer bearing.
In technique scheme, between described inner bearing and outer bearing are axial, be provided with gap.
In technique scheme, between described inner bearing and outer bearing, the outer wall of axle is provided with the annular projection that inner bearing and outer bearing are separated.
In technique scheme, the strip base plate working surface outside in described chute is provided with strip projected parts, and described strip projected parts surface contacts with outer bearing, and described strip top board working surface contacts with inner bearing surface.
In technique scheme, described chute two ends are provided with the Closed end plate of chute end part seal.
Duplex bearing of the present invention is crossed positioning device, there is following beneficial effect: because inner bearing contacts with the strip base plate with the strip top board respectively with outer bearing, but not single bearing contacts with the strip base plate with the strip top board simultaneously, when inner bearing and outer bearing during along the axial motion of chute, two bearings are pure rolling but not sliding friction, just rotating direction is contrary, can not form the interference phenomenon occurred as in background technique, simultaneously, it is as a whole that two bearings are done, and with the chute surface of contact, do not have gap.So this structure setting, not only reduced wearing and tearing, and avoid axle to produce the possibility of circumferentially rotating, guaranteed transmission accuracy.

Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail, but this embodiment should not be construed as limitation of the present invention.
Referring to Fig. 1 to Fig. 2, duplex bearing of the present invention is crossed positioning device, comprises axle 1, chute 2, inner bearing 3, outer bearing 4 and Closed end plate (not shown).Described axle 1 coaxially is fixed together with inner bearing 3 and outer bearing 4.
Referring to Fig. 3 to Fig. 4, between described inner bearing 3 and outer bearing 4, the outer wall of axle 1 is provided with the annular projection 1.1 that inner bearing 3 and outer bearing 4 are separated, to avoid between inner bearing 3 and outer bearing 4 forming interference, described axle 1 is connected with the clutch end of actuator (not shown).
Referring to Fig. 5 to Fig. 7, described chute 2 is by strip top board 2.1, strip base plate 2.2 and connects the rectangle groove that the strip side plate 2.3 of strip top board 2.1 and strip base plate 2.2 forms, strip top board 2.1 and strip base plate 2.2 are arranged in parallel, and with inner bearing 3, with outer bearing 4 is movable, coordinate respectively.The working surface of strip top board 2.1 and strip base plate 2.2 is two bearing surface correspondences respectively.
Described strip base plate 2.2 outer side surfaces are provided with strip projected parts 2.2.1, and described strip projected parts 2.2.1 surface is only limited to outer bearing 4 and contacts, and described strip top board 2.1 surfaces are only limited to inner bearing 3 and contact.Be provided with gap between described inner bearing 3 and strip side plate 2.3, to guarantee can not form interference between inner bearing 3 and strip side plate 2.3.Described chute 2 two ends are provided with Closed end plate, can store lubricant oil in chute like this, to provide lubricated, to reduce wear, reduce noise.
Because inner bearing 3 contacts with strip base plate 2.2 with strip top board 2.1 respectively with outer bearing 4, but not single bearing contacts with strip base plate 2.2 with strip top board 2.1 simultaneously, so, when inner bearing 3 and outer bearing 4, during along the axial motion of chute 2, two bearings are pure rolling but not sliding friction, and just rotating direction is contrary, can not form the interference phenomenon occurred as in background technique, simultaneously, it is as a whole that two bearings are done, and with chute 2 surface of contact, do not have gap.
In sum, duplex bearing of the present invention is crossed positioning device and not only reduced wearing and tearing when work, and has avoided axle 1 to produce the possibility of circumferentially rotating, and has guaranteed transmission accuracy.
Obviously, those skilled in the art can carry out various changes and modification and not break away from the spirit and scope of the present invention the present invention.Like this, if within of the present invention these are revised and modification belongs to the scope of the claims in the present invention and equivalent technologies thereof, the present invention also is intended to comprise these changes and modification interior.
The content be not described in detail in this specification belongs to the known prior art of professional and technical personnel in the field.
