Description
Technical field
The utility model relates to field of machining and machinebuilding technology, is specifically related to the survey instrument used in Gear Processing.
Background technology
Transverse tooth thickness refers to and comprises the basic circle arc length crossing with arbitrary tooth both sides flank profil with any one circle of point circle.Transverse tooth thickness is the important parameter needing in Gear Processing process to detect, and is also the important parameter determining gear performance.
The tooth of bevel gear is from holding greatly the conical insert shunk gradually to small end.Therefore the transverse tooth thickness of the tooth of bevel gear on different cross section is different, on same cross section, only measure size and the error that accurately could reflect transverse tooth thickness.The different between cog of detection method normally on same cross section of prior art place two 1 steel balls respectively, then detect the actual pitch of steel ball and the error of design pitch, successively indirect inspection transverse tooth thickness and error.But the own detection difficulty of spacing detecting two steel balls is just large, and measuring accuracy is not high; Require also harsh to sense environmental conditions, detection speed is slow, is difficult to, according to the timely adjusting process of testing result, be not suitable for on-line checkingi.
There is the measurement mechanism shown in Fig. 1 afterwards, analyze transverse tooth thickness and error by the H value in detection figure.But in this measurement mechanism, steel ball will be placed on circular table, then places bevel gear.And in order to ensure that steel ball and conical insert fully contact, this mesa width is limited, the center of gravity of steel ball is almost positioned at mesa edge, and stablize so steel ball is difficult to place, device uses very inconvenient.
Summary of the invention
The purpose of this utility model is to provide a kind of precision bevel gear tooth thickness measurement mechanism high, easy to use.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of bevel gear tooth thickness measurement mechanism, comprises measuring seat, measures steel ball, measures lid, locating shaft; Arrange pilot hole along measuring seat axle center, locating shaft becomes interference fit with pilot hole; Measuring seat coaxially arranges the first seam with pilot hole; Bevel gear is by endoporus own and locating shaft clearance fit; Bevel-gear spherical is positioned at the first stop portion down; Evenly place 3 in the teeth groove of bevel gear and measure steel ball, measure steel ball and measuring seat, bevel gear contact free; Measure lid to be freely placed on measurement steel ball.
Preferably, on described measuring seat, below the first seam, the second seam is set.
Preferably, described measurement covers the ring gear arranging and coincide with the tooth on bevel gear.
The beneficial effects of the utility model are: bevel-gear spherical end is placed on measuring seat, with locating shaft and the first seam location.Measure steel ball and evenly freely put into teeth groove, measure lid and cover on measurement steel ball.With measuring seat upper surface for reference field, by measuring height size, in conjunction with some design constants, obtain the distance of the first seam on steel ball end face to measuring seat, and then obtain transverse tooth thickness and the deviation thereof of detected bevel gear.Under when such measurement mechanism uses, the sphere of bevel gear surpasses, top is placed and is measured steel ball, convenient operation; The position of the upper abnormal profile of tooth of bevel gear can also be searched according to the levelness measuring lid.The accuracy of detection of device is greatly improved, and uses also very convenient.

Embodiment
Shown in Fig. 1,2, to process the bevel planet gear used in differential for vehicles, introduce structure of the present utility model and effect in detail.
For measuring the measurement mechanism of bevel planet gear 5 transverse tooth thickness, comprising measuring seat 1, measure steel ball 2, measuring lid 3, locating shaft 4.Arrange pilot hole along measuring seat 1 axle center, locating shaft 4 becomes interference fit with pilot hole.Measuring seat 1 coaxially arranges the first seam 6 with pilot hole.Bevel gear 5 is by endoporus own and locating shaft 4 clearance fit.Bevel gear 5 sphere is positioned at the first seam 6 place down.Evenly place 3 in the teeth groove of bevel gear 5 and measure steel ball 2, measure steel ball 2 and measuring seat 1, bevel gear 5 contact free.Measure lid 3 to be freely placed on measurement steel ball 2.
More preferably the second seam 7 can also be set on measuring seat 1, below the first seam 6.Second seam 7 itself is not necessary, but the surface of contact of bevel gear 5 with measuring seat 1 can be shifted to middle part by the sphere summit of bevel gear 5 by it, increases surface of contact, avoids the damage to bevel gear 5 sphere.
Preferred embodiment: measure ring gear lid 3 being arranged and coincide with the tooth on bevel gear 5.It not is the degree that will reach engagement coupling that this profile of tooth is coincide, but profile of tooth is less than the tooth on bevel gear 5.Be convenient to like this measure lid 3 more convenient on steel ball, place more reposefully, and without the need to locating shaft 4 roughly coaxially could with measurement steel ball 2 contact.
The large excircle dimension of such as bevel gear 5 is φ 46mm, and determine that on measuring seat 1, first seam 6 dimension D is φ 49.25mm, the second seam 7 dimension D 2 is φ 24.86mm, and measuring seat 1 upper surface is 11.38mm to first seam 6 of bevel gear 5 apart from H4.Select to measure steel ball 2 and be of a size of φ 7mm; Measuring lid 3 thickness H1 is 12mm.
First bevel gear 5 sphere is sleeved on locating shaft 4 down; Measuring steel ball 2 for 3 is distributed between teeth groove and measuring seat 1, contact free.Again measurement lid 3 is covered on steel ball 2.With measuring seat 1 upper surface for reference field, measuring lid 3 upper surface to the distance H3 of measuring seat 1 upper surface with dial gauge or clock gauge is 13.5mm.
According to H2=H3-H1=13.5-12=1.5mm, then H=H2+H4=1.5+11.38=12.88mm, the H value recorded compares with the H value 12.88 ± 0.05mm of design, draws transverse tooth thickness and the deviation thereof of tested bevel gear 5.
The utility model, because adopt the ventricumbent scheme of bevel gear 5 ball, so measure steel ball 2 to place steady convenience, is measured lid 3 and is also convenient to place.Whole apparatus structure is simple, easy to operate, and metrical error is little.And by the mensuration measuring lid 3 levelness, the region that bevel gear 5 transverse tooth thickness is uneven or abnormal can be inferred.Comparatively prior art is compared, and is skillfully constructed, remarkably productive.
