Abstract
The utility model provides a kind of protrusion measuring device of micron order angular contact ball bearing, so that accurate reconditioning bulge quantity.To achieve these goals, technical solutions of the utility model are as follows: described protrusion measuring device is made up of load mold (1), the instrument (4) being placed in load mold (1) center, surveying instrument (7), the measurement inner ring (10) be placed on surveying instrument (7); Load mold (1) diameter D equals bearing outer ring outside dimension; Load mold (1) center has cylindrical protrusions, and cylindrical protrusions I (3) and inner ring projection (2) are in same level, and cylindrical protrusions II (5) and outer ring projection (4) are in same level; Height of projection 5mm.Load mold (1) any one side is benchmark, must be identical with measuring center height, H=H1.The beneficial effects of the utility model are: adopt load mold as protrusion measuring device, solve the problem to bulge quantity Measurement accuracy.
Description
Technical field
The utility model relates to bearing products measurement mechanism, relates to a kind of protrusion measuring device of micron order angular contact ball bearing.
Background technology
Most of angular contact ball bearing group is fitted in certain configuration mode and uses together, and its basic configuration mode has back-to-back, face-to-face and series connection three kinds.User cannot change bearing order, otherwise by impact installation performance.Universal assembled angular contact ball bearing user can arbitrarily assembly as required, and it is inadequate that universal assembled angular contact ball bearing is only considered in product design, and also repair must grind bulge quantity in actual production process, reconditioning bulge quantity must be measured accurately.In actual production process, the bulge quantity of bearing directly do not measured by application of load G905 instrument, and the result measured is a falsity, can only use as reference.Measuring error comprises: the running accuracy error of bearing, shaft strength point not in working position, the elastic force error of measurement instrument.
Summary of the invention
The utility model provides a kind of protrusion measuring device of micron order angular contact ball bearing, so that accurate reconditioning bulge quantity.
In order to achieve the above object, technical solutions of the utility model are as follows:
Described protrusion measuring device is made up of load mold (1), the instrument (4) being placed in load mold (1) center, surveying instrument (7), the measurement inner ring (10) be placed on surveying instrument (7).
Described load mold (1) has projection, comprises the protruding I (3) of load mold (1) central cylindrical, the protruding II (5) of central cylindrical, inner ring projection (2) and outer ring projection (4); Height of projection 5mm.
Described load mold (1) diameter D equals bearing outer ring (11) outside dimension, and the outside diameter d 2 of inner ring projection (2) equals the outside dimension of bearing inner race (8); The protruding I (3) of central cylindrical is with inner ring projection (2) in same level, and the protruding II (5) of central cylindrical and outer ring projection (4) are in same level.
Any one side of described load mold (1) is benchmark, must be identical with measuring center height, H=H1.
Calculate after described load mold (1) thickness deducts bossing weight according to load mold (1) actual weight F.
The weight of described load mold (1) gets 5kg ~ 10kg.
The beneficial effects of the utility model are: adopt load mold as protrusion measuring device, solve the problem to bulge quantity Measurement accuracy.
Accompanying drawing explanation
Fig. 1 is the utility model load mold schematic diagram;
Fig. 2 is the schematic diagram measuring the bulge quantity first step;
Fig. 3 is the schematic diagram measuring bulge quantity second step.
Icon illustrates: load mold 1, inner ring projection 2, central protuberance I3, outer ring projection 4, central protuberance II5, surveying instrument 6, bearing steel ball 7, bearing inner race 8, instrument 9, measurement inner ring 10, bearing outer ring 11, bulge quantity δ.
Embodiment
Bearing to be measured actual dress ball quantity Z1 is determined by bearing preload lotus Fa and bearing steel ball quantity Z, weight F=(Z1/Z) the * Fa of load mold 1, bearing preload lotus Fa goes out according to standard deviation, calculates Z1=Z* (5 ~ 10)/Fa, Z1 round numbers.
As shown in Figure 1, protrusion measuring device load mold 1 center has cylindrical protrusions, and two sides has outer ring protruding 4 and inner ring projection 2 respectively, and each projection thickness is at 5mm; Any one side of load mold 1 is benchmark, and its height must be identical with measuring center height, H=H1.
The weight of load mold 1 gets 5kg ~ 10kg, is convenient to overturn when measuring.
With G905 apparatus measures inner ring bulge quantity δ.As shown in Figure 2, surveying instrument 7 is placed on the measurement inner ring 10 of same specification, the bearing to be measured installing steel ball is put on measurement inner ring 10, bearing inner race 5 reference field is put downwards on measurement inner ring 10, have the one side of outer ring projection 4 to be placed on bearing to be measured load mold 1, load is added on bearing outer ring 11; Swivel bearing outer ring 11 and load mold 1 adjust bias, and instrument 9 is measured at load mold center, and instrument is transferred to zero-bit; As shown in Figure 3, load mold 1 is taken off upset, load is added on bearing inner race 8, instrument 9 reads bulge quantity δ indicating value, is write on bearing inner race 8 non-referenced face by the sour pen of indicating value.The Internal and external cycle of the bearing measured is unloaded and delivers to M7440 equipment, by Internal and external cycle grinding simultaneously, reach the bulge quantity index of technical requirement.
