Description
Technical field the utility model belongs to the machine parts measurement technical field, the apparatus and method that relate to the distance between a kind of two planes parallel to each other that are used to detect mechanical component, particularly a kind of branch's pick-up unit and method that is used to detect with the biserial conical bearing end-play of inside and outside spacer ring.
The measurement of the biserial conical bearing end-play value of the inside and outside spacer ring of background technology band, the applied load piece is a supplemental measurement tool always so far, divides three steps to finish measurement result by the G903 height-gauge:
The first step: measured bearing is taken out cone spacer, be placed on the G903 height-gauge measuring table, the load piece is inserted the as above bearing inner race endoporus of an end, on the other hand rotating load piece number changes so that the axial benchmark of a row rolling body of a last end with on an end bearing inner ring rib closing, both hands promote measured bearing together with the piece of loading, on the G903 height-gauge, record height T1, at this moment, rotate the dial gauge dial plate, make dial gauge pointed zero.T1 is the bearing height value of measured bearing when the zero windage state.
Second step, the cone spacer that reduction is taken out when first step is measured, rotating load piece number changes on the other hand, so that a last end bearing inner ring, effectively contact with the corresponding end face of next end bearing inner ring with cone spacer, both hands promote measured bearing together with the load piece, and to be equal to or greater than T1 Δ T2 be the bearing height value of measured bearing when the play state is arranged recording bearing height Δ T2T2 on the G903 height-gauge.
The difference DELTA T that the 3rd step: T2 deducts T1 is the end-play value of this bearing.
Its shortcoming is:
1. when measuring T1,, need recover Roller Shaft by rotating load and effectively contact with corresponding inner ring rib to benchmark because at one group of roller of a last end, the effect of leaning on own wt makes Roller Shaft break away from pairing inner ring rib to benchmark; When measuring T2, need upper and lower two non-datum end faces of inner ring effectively be contacted with the cone spacer end face by the rotating load piece.Like this, often because of the different of piece revolution and speed of loading, when energy is arranged Roller Shaft is reliably contacted with inner ring rib to benchmark, it is inaccurate that T1, T2 two values are measured, and it is inaccurate promptly to cause end-play Δ T to calculate.
2. measuring process makes efficiency of measurement low than more complicated.
The summary of the invention the purpose of this utility model just provides a kind of simple in structure, the measurement mechanism of the band internal space ring and external space ring biserial conical bearing end-play that manufacturing expense is low, measurement is accurate, efficient is high
Technical solution of the present utility model is, a kind of measurement mechanism with internal space ring and external space ring biserial conical bearing end-play, comprise dial gauge 1, its special, also comprise locking screw 2, dial gauge pole socket 4, drop measuring staff 5, drop measuring rod seat 6, nut 7, fall pad 8, drop spacing ring 9, spring pad 10, screw 11, horizontal meter calibrating block 12, dial gauge bar 3 is a spiral marking connection with dial gauge pole socket 4, glues together locking; Drop measuring staff 5 is a spiral marking connection with drop measuring rod seat 6, and nut 7 is connected with the drop measuring staff 5 that passes drop measuring rod seat 6, and is fastening locking; Two groups of parts after fastening assemble movingly; Fall pad 8 with movingly by the circular hole on the dial gauge pole socket 4 and drop measuring rod seat 6, drop spacing ring 9 on it and spring pad 10 by screw 11 fastening connections; Above-mentioned parts install, and are placed on the horizontal meter calibrating block 12, and horizontal meter calibrating block 12 is pressed axial line and placed perpendicular to the surface level state, and the measuring basis of dial gauge pole socket 4 and drop measuring rod seat 6 is on the same surface level; Dial gauge 1 inserts in this device upper end aperture and adjusts the dial gauge insertion depth and rotate the percentage dial plate and makes dial gauge pointed zero point, and dial gauge 1 employing nut compresses the activity of cylinder interference connected mode and fixes, and tightens locking screw 2.
Horizontal meter calibrating block 12 is ring-like.
Before the measurement, the one biserial conical bearing that overlaps with inside and outside spacer ring is split into two cover single row conical bearings, its inner ring datum end face all is placed on the platform down, and inside and outside spacer ring is placed on any cover single row conical bearing upper end, and the inside and outside circle end face corresponding with it reliably contacts.Measuring process is:
A. measure an axial distance t1 who overlaps between non-datum end face of single row conical bearing inner ring and the outer ring reference edge with this measurement mechanism, show by dial gauge.
B. measure the both ends of the surface axial distance t2 that overlaps inside and outside two spacer rings of single row conical bearing with one of inside and outside spacer ring with this measurement mechanism, show by dial gauge.
The algebraic sum Δ t of c.t1 and t2 both had been the end-play of this biserial conical bearing.
Measurement range is positive and negative 1mm.
Change the width dimensions of fall pad, can make maximum measurement range equal the measurement range of selected dial gauge.
The beneficial effects of the utility model are that simple in structure, manufacturing expense is low, measurement is accurate, efficient is high.
1. when measuring in branch with the end-play of the biserial conical bearing of inside and outside spacer ring, two row rolling bodys all the time by the effect of own wt, contacts with pairing inner ring rib respectively naturally effectively, thereby make t1 and the measurement of t2 two values accurate.End-play value Δ t is calculated accurately.
2. measuring process is fairly simple, makes the efficiency of measurement height.
3. simple in structure, in light weight, improvement expenses is low.
