Abstract

The utility model discloses an assembly chamfering detector for rings of an inch conical bearing, which consists of an outer ring chamfering sample plate and an inner ring chamfering sample plate. The outer ring chamfering sample plate is in the shape of an angle square, and the inner corner thereof is made into the shape identical with a tested outer ring chamfering. The inner ring chamfering sample plate is in the shape of a T-square, and the inner corner of the cross short end thereof is made into the shape identical with a tested inner ring chamfering. The assembly chamfering of the inner ring and the outer ring of the inch conical bearing can be detected at one step, and detection is convenient, fast and high in efficiency and accuracy.

Description

Tapered roller bearing ring assembling chamfering detecting device made in Great Britain

Technical field

The utility model relates to a kind of appliance, specifically, is a kind of tapered roller bearing ring assembling chamfering detecting device made in Great Britain.

Background technology

Taper roll bearing model made in Great Britain is intensive, and quantity is a lot, according to foreign statistic, has developed more than ten ten thousand specifications, and the taper roll bearing made in Great Britain that a lot of different size models are arranged only is that internal diameter or external diameter are different; Also there is assembling high different, only differs several millimeters at zero point zero; It is different also to have plenty of the assembling chamfering, and specifications and models are also different, is two kinds of taper roll bearings made in Great Britain of 13620 and 13621 such as model; Its external diameter is 69.012mm, highly is 15.083mm, and internal diameter is also identical; But 13620 assembling chamfering is R1.6mm, and 13621 chamfering is R4.6mm; The assembling chamfering of taper roll bearing made in Great Britain has significantly different with the chamfering of conventional mechanical product; The chamfering of conventional mechanical product is generally the quadrant arc of linear pattern or standard, installs for ease, and taper roll bearing assembling chamfer design made in Great Britain becomes two sections straight lines and one section camber line to form (see figure 1); Whether the assembling chamfering directly has influence on client's installation convenient; So taper roll bearing made in Great Britain is very high to the inspection requirements of assembling chamfering, before the utility model was made, conventional detection method was to adopt vernier caliper to measure the radical length and the axial length (promptly assembling the degree of depth on chamfering both sides) of assembling chamfering respectively; To use eye to judge whether the degree of depth rod end point of vernier caliper overlaps with assembling chamfering intersection point during detection; Eyes are easy to fatigue, and accuracy in detection is poor, and cover taper roll bearing made in Great Britain has inside race assembling chamfering and two assemblings of outer collar assembling chamfering chamfering; Radial dimension and the axial dimension of measuring the assembling chamfering respectively will detect four times, and efficient is not high.

Summary of the invention

The purpose of the utility model provides a kind of conical roller bearing ring chamfering detecting device made in Great Britain, but an assembling of one-time detection taper roll bearing made in Great Britain chamfering, and check convenient, fastly, and efficient is high, and accuracy is high.

The purpose of the utility model realizes through following technical scheme:

A kind of conical roller bearing ring chamfering detecting device made in Great Britain; It is characterized in that: this detecting device is made up of outer collar chamfering model and inside race chamfering model; Said outer collar chamfering model is the angle square shape; Be slightly less than the height of tested outer collar in the short end of angle square along length, be slightly less than the external diameter of tested outer collar in the long end along length, interiorly process and the identical shape of tested outer collar chamfering along corner; Said inside race chamfering model is the T-square shape; T-square crossfoot length is slightly larger than the big end external diameter of tested inside race; One side of perpendicular chi deflection crossfoot highly is slightly larger than tested inside race height, in the short end of crossfoot, processes and the identical shape of tested inside race chamfering along corner.

Among Fig. 2, Fig. 3: 1. outer collar chamfering model, 2. outer collar, 3. inside race chamfering model, 4. inside race, 5. chamfering.

Embodiment

Below in conjunction with accompanying drawing 2, Fig. 3 the utility model conical bearing assembling made in Great Britain chamfering detecting device is described further.

Fig. 2 embodiment is that a detection model is 13621 conical bearing outer collar chamfering model made in Great Britain, this model bearing outside collar external diameter 69.012mm, height 15.083mm; The assembling chamfering is R4.6, axial dimension (horizontal direction) 3.2mm (+0.6/0), radial dimension (vertical) 2.7mm (+0.3/0); Supporting design chamfering model profile is the angle square shape, and along length 15mm, long end is interior along length 69mm in the angle square weak point end; Wide 8mm-the 12mm of chi, thickness 2mm-3mm interiorly processes and the identical shape of tested outer collar chamfering along corner; In outer collar chamfering model along the turning intersection point a distance respectively open a groove, the horizontal direction groove from interior along the turning intersection point 3.2mm, groove width 0.6mm; The vertical groove from interior along the turning intersection point 2.7mm, groove width 0.3mm, two groove depth 2mm.

Fig. 3 embodiment is one, and to detect model be 13685 conical bearing inside race chamfering model made in Great Britain, this inside race can with the 13621 and 13620 outer collar finished product bearing that completes a set, its big end external diameter 53.02 mm; Height 19.015 mm, the assembling chamfering is R5.6, axial dimension (horizontal direction) 4.4mm (+0.6/0); Radial dimension (vertical) 3.9mm (+0.3/0), supporting design chamfering model profile is the T-square shape, T-square crossfoot length is 54mm; One side of perpendicular chi deflection crossfoot, the crossfoot weak point that forms length 8mm-12mm is held, and perpendicular chi height is 19.5mm; In the short end of crossfoot, process and the identical shape of tested inside race chamfering along corner, in inside race chamfering model along the turning intersection point a distance respectively open a groove, the horizontal direction groove leave interior along the turning intersection point 4.4mm; Groove width 0.6mm; The vertical groove from interior along the turning intersection point 3.9mm, groove width 0.3mm, two groove depth 2mm.

The application of the utility model conical bearing assembling made in Great Britain chamfering detecting device when detecting the bearing outside collar chamfering, is used angle square shape chamfering model; With edge and the snap of bearing ring external diameter in the short end of angle square; The plane snap of edge and bearing ring in the long end of angle square, if the outer collar chamfering contacts not light leak fully with the chamfering of angle square shape chamfering model, perhaps suitable some light leak of interlude and both sides light leak not; Judge that then the outer collar chamfering is qualified; Otherwise, if interlude light leak and there is light leak on both sides not judges that then the outer collar chamfering is defective; When detecting the bearing inner ring chamfering, use T-square shape chamfering model, resolution principle detects identical with the outer collar chamfering.
