Description

A kind of bearing axial clearance detector

Technical field

The utility model designs bearing detecting device, especially a kind of bearing axial clearance detector.

Background technique

Bearing clearance is the gap between bearing roller and bearing internal external circle shell.So-called bearing clearance, i.e. spindle are held When not being installed on axis or bearing housing, a side of its inner ring or outer ring is fixed, then makes the loose side of bearing clearance Amount of movement when moving radially or axially.According to moving direction, radial internal clearance and end-play can be divided into.Trip when operating The size of gap (referred to as working gap) has an impact to performances such as the rolling fatigue life of bearing, temperature rise, noise, vibrations, as axis The important parameter held, often structure is complicated for existing Bearing testing instrument, with high costs, and operates complicated.

Utility model content

The purpose of this utility model is: it is simple to provide a kind of structure, easy to operate, and testing result accuracy is high, at low cost The detection device of honest and clean bearing axial play.

To achieve the above object, the utility model provides following technical solution: a kind of bearing axial clearance detector, Including substrate, the height-adjustable support column being installed on substrate, bearing fixing device, measuring device, wherein the bearing Fixed device is mounted on the upper surface of substrate, including supporting table, pressing plate, fastening bolt, the supporting table and pressing plate, fastening bolt The fixation by bearing inner race level matched, and keep its outer ring hanging；The measuring device connects with bearing outer ring lower surface Touching.

Further, the pressing plate radially offers disassembly slot, and the disassembly slot groove width is adapted with fastening bolt diameter.

Further, it is provided with guide groove on the substrate, measuring device is slidably mounted in guide groove；The measuring device Including sliding block, detection table, described sliding block or so groove is fastened in guide groove, and can be slided along guide groove, detection table probe court On be mounted on sliding block, probe measurement plane is parallel with the required measurement plane of outer ring of bearing.

Further, the fine tuning hole of mountable measurement table there are two being arranged on the sliding block.

The utility model has the following beneficial effects: can accurately measure the axial play of bearing by simple mechanical structure Gap, and the utility model use is easy, low in cost, makes it possible to the large-scale popularization in enterprise produces.

Specific embodiment

Specific embodiment of the utility model is illustrated with reference to the accompanying drawing:

As shown in Fig. 1 ~ 4, the bearing axial clearance detector 1 includes: bearing fixing device 11, substrate 12, support Column 13, measuring device 14；The support column is height-adjustable to be installed on substrate, and substrate is used to support, and keeps its holding horizontal； The bearing fixing device is mounted on the upper surface of substrate, comprising: supporting table 111, pressing plate 112, fastening bolt 113, the branch The inner ring 151 of bearing 15 is fastened and keeps horizontal by support platform and pressing plate, fastening bolt mating reaction, keeps outer ring 152 vacantly, And it horizontal can be freely rotated.Wherein the supporting table Upper cylindrical diameter is adapted with bearing shaft hole diameter, is nested with limitation In the radial action of supporting table upper bearing (metal), and the height of Upper cylindrical is less than or equal to the width of bearing inner race；Supporting table lower part circle Column diameter is greater than bearing shaft hole diameter, and is not in contact with bearing outer ring, to limit the axial action of bearing, the measurement dress It sets and is in contact with bearing outer ring lower surface.

Further, the pressing plate has been arranged radially disassembly slot 1121, and the disassembly groove width is adapted with fastening bolt, Keep pressing plate i.e. dismountable in the case where not removing fastening bolt, so that the dismounting of bearing is more fast.

Further, the substrate offers guide groove 121, and measuring device is slidably mounted in guide groove, so that bearing Axially measured device can adjust the measurement range of measuring device, thus be suitable for the bearing axial play of different-diameter size Measurement.The measuring device includes sliding block 142 adapted to the guide groove, and the sliding block is I-shape construction, and left and right groove card is set In the guide groove of base plan, it to limit its moving direction, slide it can along guide groove；Detection table 141 is installed on sliding block, it is excellent Choosing, detection side be dial gauge or amesdial, the measurement plane of the probe 1411 of the detection table be fixed in supporting table Bearing outer ring plane is parallel.

Further, the fine tuning hole 1421 there are two mountable measurement table is also set up on the sliding block, for adjusting measurement Device minimum measures the range of radius and maximum measurement radius.

The working method of the utility model are as follows: first by adjusting support column, substrate is adjusted to horizontality.It again will measurement The detection plane of the probe of detection table is debugged in device, is allowed to keep phase same level with the upper surface of supporting table lower cylindrical Highly.Then the fastening bolt on bearing fixing device is unclamped, extracts pressing plate out, and bearing holder (housing, cover) to be measured is put into supporting table, After bearing is in place, pressing plate is uniformly covered on the upper surface of bearing inner race, fastening bolt is tightened after, make pressing plate Bearing is compressed, fixes it by the inner ring of bearing.The outer ring of bearing is horizontal hanging at this time, and opposite inner ring has axial position Move space, the displacement cause detection table numerical value change be bearing end-play, measure clearance when, rolling bearing outer ring, Measured numerical value is recorded, and is averaged out after numerical value as final bearing clearance numerical value.
