Description

A kind of worm-gear tooth pivoting support
Technical field
The utility model relates to pivoting support technical field, especially relates to a kind of worm-gear tooth pivoting support.
Background technique
Pivoting support is the nearly 40 years novel mechanical component worldwide risen gradually, and it has the formation such as Internal and external cycle, rolling element.Pivoting support is a kind of large size bearing that can bear combined load, can bear larger axial, radial load and tilting moment simultaneously.Pivoting support is applied very extensive in real industry, and being called by people: " joint of machine ", is need between two articles to do relative rotation motion, needs again the necessary important transmission part of machinery simultaneously bearing axial force, radial force, tilting moment.Along with developing rapidly of machinery industry, pivoting support is widely used in industries such as ship equipment, engineering machinery, light industry and machinery, metallurgical machinery, medical machinery, industrial machineries.
Pivoting support conventional gear is with gear transmission mode, gear transmission realizes by the wide follower point exterior feature that promotes successively of driving wheel point, the shortcoming that gear transmits manufactures with installation precision high exactly, cost is high, be not suitable for the transmission between remote diaxon, velocity ratio is little, sometimes needs the occasion gear transmission of big speed ratio to be just not suitable for.Pass through tooth after working for a long time simultaneously and easily wear and tear, and causing bumpy motion, occurring abnormal sound.
Model utility content
The purpose of this utility model is exactly to solve the problem, and provides a kind of worm-gear tooth pivoting support, the advantages such as compact structure, velocity ratio are large, stable drive that it has.
To achieve these goals, the utility model adopts following technological scheme:
A kind of worm-gear tooth pivoting support, comprise inner ring, outer ring and ball, described inner ring is arranged in the mounting groove of described outer ring, raceway is provided with between the inner circumferential face of the mounting groove of described outer ring and the outer circumferential surface of inner ring, described ball is evenly distributed in described raceway, the outer circumferential surface of described outer ring is provided with projection, and described projection is provided with for the worm-gear tooth with worm meshing; Lay respectively at the lower survey raceway of the upper and lower both sides of described ball, the center line of upside raceway is parallel to each other with the vertical center line of described ball respectively, and lays respectively at the inside and outside both sides of the vertical center line of described ball.
Preferably, also comprise Stamping Steel Ribbon, the upside of described raceway is located at by Stamping Steel Ribbon.
Preferably, the cross central line of described worm screw is positioned at the upside of the cross central line of ball.
Preferably, spacing block is provided with between described adjacent ball.
Preferably, the inner circumference of described inner ring is provided with oil nozzle.
Preferably, described inner ring and outer ring are equipped with mounting hole.
Preferably, the modulus of described worm-gear tooth is 3, and the number of teeth is 120, and tooth-shape angle is 20 °, and deformation coefficient is 0.
Preferably, described Stamping Steel Ribbon is I-3 rubber.
Preferably, described ball is steel ball, and described steel ball is GCr15 steel.
Preferably, the upper plane of described inner ring is positioned at the top of the upper plane of described outer ring, and the described inner ring part raised relative to outer ring is provided with groove, for convenience detach.
The beneficial effects of the utility model: the utility model compact structure; Changing involute tooth is worm-gear tooth, and makes other change described above, and velocity ratio is large, stable drive, and the structure of this model utility has reliable self-locking performance under certain condition; Inner ring is arranged in the mounting groove of outer ring, only needs to arrange Stamping Steel Ribbon in the downside of raceway and can prevent dust and greasy dirt from entering raceway inside; The part raised relative to outer ring at inner ring arranges groove, for convenience detach, install, location.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram.
Wherein, 1. outer ring; 2. inner ring; 3. ball; 4. worm-gear tooth; 5. worm screw; 6. protruding; 7. oil nozzle; 8. mounting groove; 9. mounting hole; 10. Stamping Steel Ribbon; 11. raceways.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As described in Figure 1, a kind of worm-gear tooth pivoting support, comprise inner ring 2, outer ring 1 and ball 3, Stamping Steel Ribbon 10, inner ring 2 is arranged in the mounting groove 8 on the upside of outer ring 1, raceway 11 is provided with between the inner circumferential face of the mounting groove 8 of outer ring 1 and the outer circumferential surface of inner ring 2, ball 3 is evenly distributed in raceway 11, and the outer circumferential surface of outer ring 1 is provided with protruding 6, and protruding 6 are provided with the worm-gear tooth 4 for engaging with worm screw 5.Lay respectively at the lower survey raceway of the upper and lower both sides of ball 3, the center line of upside raceway is parallel to each other with the vertical center line of ball 3 respectively, and lays respectively at the inside and outside both sides of the vertical center line of ball 3.The upside of raceway 11 is located at by Stamping Steel Ribbon.The cross central line of worm screw 5 is positioned at the upside of the cross central line of ball 3.Spacing block is provided with between adjacent ball 3. spacing block is nylon material.The inner circumference of inner ring 2 is provided with oil nozzle 7.Inner ring 2 and outer ring 1 are equipped with mounting hole 9.The modulus of worm-gear tooth 4 is 3, and the number of teeth is 120, and tooth-shape angle is 20 °, and deformation coefficient is 0.Stamping Steel Ribbon 10 is I-3 rubber.Ball 3 is steel ball, and described steel ball is GCr15 steel.The upper plane of inner ring 2 is positioned at the top of the upper plane of described outer ring 1, and described inner ring 2 part raised relative to outer ring 1 is provided with groove.
