The reasonability of stability and carrying when being moved for the slew gear that ensures entirely to feel relieved, as of the present utility model A kind of preferably implementation method, centering ring 331 is respectively by the first centering ring 3311 (upper ring A), the second centering ring 3312 (lower ring B) Constituted with centering ring link 3313, the first and second centering rings are symmetrical arranged and connect into one through centering ring link 3313 Body, in other words, the first and second centering rings are respectively fixedly connected with the two ends of centering ring link 3313；First and second centering rings Outer surface is equipped with multiple first rolling members 3331, to ensure the rotary stability of rotating ring.Correspondingly, rotating ring 332 also divides It is to be socketed with the first and second rotating rings, the first centering ring 3311 and the concentric of the first rotating ring 3321, the second centering ring 3312 It is socketed with the concentric of the second rotating ring 3322, the inner surface of each ring body is mutually cut into rotary rail with the first roller 3331a parts.

Additionally, the inner surface of the first and second centering rings is provided with the second rolling assembly 334, whole centering turn-around machine is capable of achieving Structure moves vertically under being oriented to through the second rolling assembly 334 while gyration along gyratory directions, i.e. the first rolling assembly 444 Centerline direction moves vertically；Second rolling assembly 334 is made up of multiple second rolling members 3341, and the second rolling member 3341 is by Second wheel 3341a, the second shaft stool 3341b, the second bearing 3341c compositions；Similarly, roll (motion) carrier and be arranged in second In roller.As a kind of preferably implementation method, the two ends that the first and second centering rings are not connected with centering ring link 3314 Portion adds multiple second rolling members 3341, with the stationarity for ensureing entirely to feel relieved during slew gear motion；Also dependent on load-bearing or Mobile rigidity needs to add the second rolling member 3341, is defined by the stability for ensureing motion, is not construed as the second rolling member 3341 particular location uniqueness.

It is noted that be eliminate direction of rotation on radial deflection, and rotating ring 332 with centering ring 331 together Linear velocity difference during motion and the axial displacement that produces, in other words, for implement this centering slew gear can in company with have revolution and The requirement that the function executing unit part of axial movement is synchronously axially moved, utility model people adds the 3rd rolling group on the basis of the above Part 335, for the axial limiting of rotating ring 332, the 3rd rolling assembly 335 is made up of multiple 3rd rolling members 3351, Tu11Wei The partial enlarged drawing of the 3rd rolling member, as shown in figure 11, the 3rd rolling assembly 335 includes multiple 3rd rolling members 3351, the 3rd Rolling member 3351 includes the 3rd pair of rollers 3351a, shaft stool to 3351b and three abutments 3351c, the 3rd pair of rollers 3351a points The ring of the first and second centering rings is not connected to 3351b independent connection three abutments 3351c, three abutments 3351c through shaft stool External surface, the first and second rotating ring ring body two ends of the 3rd pair of rollers 3351a sandwicheds rotating ring 332；Wherein the 3rd roller It is taper cone pulley, correspondingly, the nearly centering ring 331 of taper cone pulley smaller part；Therefore between the sandwiched of the rotating ring 332 taper clip wheel pair, therefore One and second two end faces of rotating ring be respectively the track of the 3rd pair of rollers 3351a, the rolling of every 1 the 3rd rolling member 3351 The spacing distance of circle is matched therewith rotation ring body rail thicknesses direction and forms rolling pair, so that the centering slew gear exists Realize simultaneously doing gyration when being axially moved.Used as a kind of preferably implementation method, the taper of taper cone pulley is by speed of gyration Selected, preferably speed angle bus is intersected in the centre of gyration point institute angulation angle of mechanism, to ensure the 3rd rolling assembly 335 Rolling circle is to wait linear speed taper；It is capable of achieving the centering slew gear big small end speed angle when rotating identical to ensure the steady of revolution Qualitative and load-bearing rigidity simultaneously causes that frictional force is minimum value.

As a kind of preferably implementation method, as shown in fig. 7, the stability to ensure motion, first, second, third rolling The center line of dynamic component is coaxially disposed, and wherein rolling member is circumferentially evenly arranged, and is preferably uniform staggered with.Now, the first rolling Dynamic (radial rolling element) the rolling circle center of component 333 and the line of second rolling assembly 334 (axial rolling body) axial center point Extended line is by rotating ring 332 and the rotary middle point of centering ring 331.

In actual applications, rotating ring is connected and constitutes a centering with having lifting or translation, the workpiece of spinfunction requirement Slewing equipment, it is preferred that in implementation method of the present utility model, as shown in fig. 7, the centering slewing equipment is set in mandrel 32 On, and the periphery of the cross section of mandrel 32 is non-circular and tangent with the second roller 3341a parts；Now it is connected with rotating ring 332 Workpiece can be rotated with rotating ring 332, and moved along mandrel 32 with centering ring 331, when mandrel 32 is set perpendicular to the ground, workpiece Liftable；When the parallel ground of mandrel 32 is set, workpiece can translation.On the basis of above-described embodiment, a kind of specific implementation In example, centering rotating part 30 also includes being set on mandrel 32, is located at the dust-proof mechanism 34 on the top of fixed supporting mechanism 31, leads to Dust-proof mechanism 34 is crossed, in efficiently avoid heap reclaiming process, dust enters various caused by the fixed inside of supporting mechanism 31 Adverse effect.

In sum, the centering rotating part for being provided in the embodiment of the present disclosure, by being equipped with the first and second rollings simultaneously Component parts do the demand of gyration and linear motion simultaneously；Compound fortune is realized by using each independent motion secondary combination It is dynamic so that each modular construction is simple, be easy to making and easy to maintenance；Arranged by multiple first, second Hes by ring body The rolling pair of the 3rd rolling member composition, meets after mounting simultaneously, also realizing that mechanism is vertical, turn round directed movement functional requirement Large scale equipment each station at the scene under, can bear the load of three dimensions produced during by operation；By using Two rolling assemblies so that coordinate the line slideway precision prescribed reduction that mandrel is later, it is easy to make, be easy to safeguard；By that will determine Heart slew gear is arranged on to be had on the parts of linear motion function, is driven the 3rd rolling assembly and is made moving component sheet by the part The body free degree is constrained, that is, realizes that boning out campaign at an arbitrary position and centering revolution are completed simultaneously.
