Abstract
The utility model relates to a special meshing device base for detecting worm and gear meshing precision, which can effectively prevent the surface of a meshing mandrel of a worm from being worn and can ensure that the worm and gear meshing precision is detected. The special meshing device base comprises a meshing device base, wherein two ends of a bracket in the meshing device base are provided with concave table faces, the bottom end of each concave table face is fixedly and internally provided with a bottom plate, a concentrated ball collar is arranged in the bracket and positioned on the bottom plate, a rotating sleeve is of a flange structure and a rotating sleeve flange is positioned on the concave table face on the upper end face of the bracket through a thrust bearing. The special meshing device base has the advantages that sliding friction is changed into rolling friction, thus abrasion on the surface of the meshing mandrel of the worm can be avoided, and worm and gear meshing precision detection is ensured; and precision retaining ability of parts is greatly increased, part failure caused by abrasion is avoided, so that detection cost is greatly reduced, and detection precision is greatly improved.
Description
Technical field
The utility model relates to a kind of worm gear of can avoiding effectively and meshes the axle surface abrasion; Can guarantee the special use engagement appearance base that the worm and gear accuracy of mesh detects that is used for of worm gear, worm mesh accuracy test again, belong to worm and gear engagement detector base and make the field.
Background technology
CN2557943Y, title " worm gear, worm mesh precision adjustment detecting device " comprise interconnective worm screw vertical centre measurement structure and worm gear axial centre measurement structure, a detecting device; Worm screw vertical centre measurement structure comprises: worm screw vertical centre adjustment dial, with the worm screw vertical centre locating ring of its one; Also comprise the upper and lower demarcation of worm screw the vertical centre cylindrical shell and upper and lower vertical string locating device that are in turn connected into one and have same longitudinal center line; Upper and lower horizontal positioning device; Coil all-in-one-piece worm screw radial center mark post in the horizontal direction with adjustment; Worm gear axial centre measurement structure comprises: at the horizontal opposite position of worm screw radial center mark post, and a worm gear axial centre mark post of setting; The gear vertical centre adjustment dial of one horizontal with it, gear vertical centre locating ring, upper and lower gear vertical centre is demarcated cylindrical shell; Worm gear and worm screw are accurately cooperated and be difficult for being worn, thereby prolong the serviceable life of worm gear, worm screw, reduced cost.Its weak point: adopted hole and axle to carry out clearance fit, when relatively rotating, be sliding friction, friction factor is big, causes axle, the hole is easy to wear, and undue wear simultaneously reduces bearing accuracy gradually so that instrument lost efficacy very soon.
The utility model content
Purpose of design: avoid the weak point in the above-mentioned background technology, design a kind of worm gear of can avoiding effectively and mesh the axle surface abrasion, can guarantee the special use engagement appearance base that the worm and gear accuracy of mesh detects that is used for of worm gear, worm mesh accuracy test again.
Design proposal: in order to realize above-mentioned purpose of design.Dense ball set places in the engagement appearance base endoporus, and the design that its external diameter and endoporus internal diameter match is the major technique characteristic of the utility model.The purpose of doing like this is: when worm and wheel meshed, worm screw was rotated and drives the worm gear rotation, and worm gear connects firmly with the engagement axle; The engagement axle meshes the internal control of appearance base relatively and rotates, and institute's dense ball set is the set of the steel ball of band retainer, places in the engagement appearance base endoporus; Axle contacts with dense ball set; Original sliding friction is become rolling friction, and friction factor reduces greatly, avoids the part failure that should wear and tear and cause.Pivoted housing and base plate lay respectively at engagement appearance base two ends up and down, form cavity with the base endoporus, and dense ball set places cavity, and it is unlikelyly deviate from the air in base.
Technical scheme: be used for the special use engagement appearance base that the worm and gear accuracy of mesh detects; It comprises engagement appearance base; Support two ends in the said engagement appearance base are the concave station face; The intrinsic base plate that is built-in with in concave station face bottom, dense ball set is positioned at support and dense ball set is positioned on the base plate, and pivoted housing is flange arrangement and pivoted housing flange edge is positioned on the concave station face of support upper surface through thrust bearing.
The utility model is compared with background technology; Sliding friction is become rolling friction, not only avoid the abrasion on worm gear engagement axle surface, guaranteed the detection of worm gear, worm mesh precision; And close the part precision retentivity and increase greatly; Avoided the part failure that causes because of wearing and tearing, made and detect cost and reduce greatly, accuracy of detection improves greatly.
Description of drawings
Fig. 1 is the structural representation of close pearl circle engaged with base.
Embodiment
Embodiment 1: with reference to accompanying drawing 1.Be used for the special use engagement appearance base that the worm and gear accuracy of mesh detects; It comprises engagement appearance base; Base 6 two ends in the said engagement appearance base are the concave station face; The intrinsic base plate 8 that is built-in with in concave station face bottom, dense ball set 9 is positioned at base 6 and dense ball set 9 is positioned on the base plate 8, and pivoted housing 1 is flange arrangement and pivoted housing 1 flange edge is positioned on the concave station face of base 6 upper surfaces through thrust bearing 5.6 of said pivoted housing 1 and bases are connected through end cap 3.Promptly; Pivoted housing 1 is combined through cross sunk screw 2 with end cap 3, and pivoted housing 1 is supported on the base 6 through thrust bearing 5, and slotted countersunk flat head screw 4 is screwed on the end cap; Slotted countersunk flat head screw 4 ends are stretched in the base annular groove; Make end cap 3, thrust bearing 5, base 6 can rotate flexibly and be unlikely to throw off, dense ball set 9 be the steel ball set of band retainer, and base plate 8 connects firmly through hexagon socket cap head screw 7 and base 6; Form cavity with base 6 endoporus, can make that dense ball set 9 is unlikely in the base endoporus to be deviate from.During use, the engagement axle that is connecting firmly worm gear is inserted in the dense ball set 9, when worm gear rotates, driven the engagement axle and rotate, engagement axle surface that steel ball contacts with it and susceptor surface are that track rolls, and base and engagement axle are relatively rotated.
The method of work that is used for the special use engagement appearance base of worm and gear accuracy of mesh detection; Worm gear is fixed on the engagement axle; The engagement axle insert in the dense ball set 9 through pivoted housing 1 and worm gear engagement axle and dense ball set 9 between form to roll and cooperate, when worm gear rotates, drive and mesh the axle rotation; Steel ball in its dense ball set 9 is the track rolling with the concave station surface of engagement axle surface and base 6 upper surfaces; Base 6 and engagement axle are relatively rotated, and quality of fit has been guaranteed in the part abrasion of both having avoided hard grind to cause again.
What need understand is: though the foregoing description is to the mentality of designing of the utility model detailed text description of contrasting; But these text descriptions; Just the simple text of the utility model mentality of designing is described; Rather than to the restriction of the utility model mentality of designing, any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection domain of the utility model.
