Abstract
A kind of eccentric wheel of adjustable eccentric amount, including the capping of bearing inner sleeve, bearing, bearing, bearing outside, bolt, the bearing outside are socketed bearing, the bearing holder (housing, cover) joint bearing capping and bearing inner sleeve；The bearing capping abuts against cooperation with bearing composition, and the intermediate U-shaped opening being equipped with for connecting shaft, the U-shaped opening both sides are equipped with elongated slot, centre bore corresponding with U-shaped opening is equipped among the bearing inner sleeve, the centre bore side is equipped with threaded hole corresponding with elongated slot respectively, and the elongated slot is bolted cooperation with threaded hole.When needing to adjust eccentricity, the bolt in bearing capping is unclamped, toward the relative position of elongated slot length direction movement bearing capping and bearing inner sleeve, and then the centre-to-centre spacing in the center of circle and the bearing inner sleeve endoporus center of circle of bearing outside is adjusted, to adjust eccentricity size.
Description
Technical field
The utility model is related to machinery fields, and in particular to a kind of eccentric wheel of adjustable eccentric amount.
Background technology
Can usually shaft be used to drive eccentric mechanism in mechanical equipment, to complete intermittent movement requirement.Previous
Eccentric wheel structure is that eccentricity not equal mounting hole is drilled out on the disc of central shaft surrounding, to be achieved the tune of eccentricity
Section.It is pretty troublesome that eccentricity is adjusted in this way, and can not achieve continuous accurate adjusting.
Utility model content
To solve the above-mentioned problems, the utility model provides a kind of eccentric wheel of adjustable eccentric amount：
A kind of eccentric wheel of adjustable eccentric amount, including the capping of bearing inner sleeve, bearing, bearing, bearing outside, bolt, it is described
Bearing outside is socketed bearing, the bearing holder (housing, cover) joint bearing capping and bearing inner sleeve；The bearing capping is abutted against with bearing composition matches
It closes, and the intermediate U-shaped opening being equipped with for connecting shaft, the U-shaped opening both sides are equipped with elongated slot, among the bearing inner sleeve
Equipped with centre bore corresponding with U-shaped opening, the centre bore side is equipped with threaded hole corresponding with elongated slot respectively, the elongated slot
It is bolted cooperation with threaded hole.When needing to adjust eccentricity, the bolt in bearing capping is unclamped, toward long slot length side
To the relative position of mobile bearing capping and bearing inner sleeve, and then adjust the center of circle and the bearing inner sleeve endoporus center of circle of bearing outside
Centre-to-centre spacing, to adjust eccentricity size.
Bearing capping lower end is equipped with the round screens portion of protrusion, the endoporus structure that the circle screens portion is equipped with bearing
It is fixed at screens, effectively reduces the mutual gouging abrasion of bearing capping and bearing in the process of running, the two is avoided to be mutually disengaged.
The bearing inner sleeve upper end is equipped with the top position portion of protrusion, and the top position portion is corresponding with round screens portion and less than interior
Hole, the sum of the top position portion and the thickness in round screens portion are greater than or equal to the thickness of bearing.
The bearing outside is radially provided with interconnecting piece, and the interconnecting piece is positive hexagonal column structure outstanding and centre is set
There is threaded hole, both can be used for connecting external connector with cooperation is abutted against to external component.
The utility model has the advantages that：It can be by unclamping the bolt in bearing capping, toward long slot length side
To the relative position of mobile bearing capping and bearing inner sleeve, and then adjust the center of circle and the bearing inner sleeve endoporus center of circle of bearing outside
Centre-to-centre spacing, it is simple and practicable to adjust eccentricity size.
Description of the drawings
Attached drawing 1 is the structural schematic diagram of embodiment.
1 bearing inner sleeve, the capping of 2 bearings, 3 bearings, 4 bearing outsides, 5 round screens portions, 6 top position portions, 7 interconnecting pieces.
Specific implementation mode
The utility model is further described with embodiment below in conjunction with the accompanying drawings.
Embodiment：A kind of eccentric wheel of adjustable eccentric amount, including bearing inner sleeve 1, bearing capping 2, bearing 3, bearing outside
4, bolt, the bearing outside 4 are socketed bearing 3, and the bearing 3 is socketed bearing capping 2 and bearing inner sleeve 1；The bearing capping 2
Cooperation, and the intermediate U-shaped opening being equipped with for connecting shaft are abutted against with the composition of bearing 3, the U-shaped opening both sides are equipped with length
Slot, is equipped with centre bore corresponding with U-shaped opening among the bearing inner sleeve 1, the centre bore side be equipped with respectively with elongated slot phase
Corresponding threaded hole, the elongated slot are bolted cooperation with threaded hole.When needing to adjust eccentricity, bearing capping is unclamped
Bolt on 2 toward the relative position of elongated slot length direction movement bearing capping 2 and bearing inner sleeve 1, and then adjusts bearing outside 4
The center of circle and the 1 endoporus center of circle of bearing inner sleeve centre-to-centre spacing, to adjust eccentricity size.The bearing covers 2 lower ends equipped with convex
The round screens portion 5 gone out, the circle screens portion 5 constitute screens with the endoporus that bearing 3 is equipped with and fix, effectively reduce and running
The mutual gouging abrasion of journey middle (center) bearing capping 2 and bearing 3, avoids the two from being mutually disengaged.1 upper end of the bearing inner sleeve is equipped with protrusion
Top position portion 6, the top position portion 6 is correspondings with round screens portion 5 and is less than endoporus, the thickness in the top position portion 6 and circle screens portion 5
The sum of degree is greater than or equal to the thickness of bearing 3.The bearing outside 4 is radially provided with interconnecting piece 7, and the interconnecting piece 7 is outstanding
Positive hexagonal column structure and it is intermediate be equipped with threaded hole, both can be used for connect outside with cooperation is abutted against to external component
The connector in portion.
Obviously, above-described embodiment of the utility model is merely to illustrate that the utility model example, and is not
Restriction to the embodiment of the utility model.For those of ordinary skill in the art, on the basis of above description
On can also make other various forms of variations or variation.There is no need and unable to give poor example to all embodiments.
And these connotation changes and variations that derived from for belonging to the utility model still fall within the utility model
Protection domain.
