Background
When measuring antifriction bearing play at present, insert between the track inside and outside the bearing with the lead wire usually, let the bearing ball roll the lead wire, then measure the lead wire indentation with the micrometer and obtain bearing play. The measurement mode has the problems that the manual lead wire rolling is labor-consuming, the lead wire is easy to be folded when the force is not enough, and particularly, the lead wire rolling by the bearing is very difficult when the bearing play is not large; secondly, the measuring method has more procedures, and the generated errors are superposed to influence the accuracy of the measuring result.
SUMMERY OF THE UTILITY MODEL
In order to overcome the current hard, the unsafe not enough of measuring result of operation when measuring the bearing clearance with the lead wire, the utility model provides a antifriction bearing play measuring device, this antifriction bearing play measuring device have reduced the operating procedure who measures antifriction bearing play, reduce the operation degree of difficulty, have improved measurement accuracy greatly.
The technical scheme of the utility model is that: the utility model provides a antifriction bearing clearance measuring device that moves about, which comprises a bracket, the percentage table is connected through the percentage table fixed pin that can reciprocate at the support top, the support middle part is connected with fixed pin and the bearing in the bearing that can reciprocate respectively under the rail fixed pin on the rail, two eccentric cylinders are connected through the pivot in the support bottom, eccentric cylinder lies in the bearing in the rail under the fixed pin with one side, and two eccentric cylindrical centers and bearing in the rail under the fixed pin center adjust well, be connected with intermeshing's synchromesh gear in the pivot of two eccentric cylinder rear sides.
An eccentric expansion sleeve is connected to the fixed pin on the bearing inner rail, and the inner diameter and the outer diameter of the eccentric expansion sleeve are not concentric.
The eccentric cylinder and the synchronous gear are fixed on the rotating shaft through keys.
The utility model discloses following beneficial effect has: owing to take above-mentioned scheme, this measuring device simple structure, safe and reliable, convenient to carry has reduced the operation degree of difficulty of measuring antifriction bearing play value, has shortened measuring operating time, and the traditional lead wire pressing method is measured the play value of bearing, and the operation is once, and the time is on average 20 minutes, and adopts the utility model discloses a measuring device, the operation is once, only is 3 minutes for the time, has improved measurement accuracy moreover.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
shown by fig. 1 to 3, a antifriction bearing clearance measuring device that moves about, including support 7, support 7 is the T font of putting upside down, including the flat board of bottom and the riser on upper portion, wherein the riser top is connected with percentage table fixed pin 1 that can reciprocate, is connected with the percentage table on the percentage table fixed pin 1, and the riser middle part is connected with fixed pin 2 and bearing inner rail lower fixing pin 3 on the bearing inner rail that can reciprocate respectively, be connected with eccentric bloated tight sleeve 6 on the bearing inner rail on the fixed pin 2, 6 internal diameters of eccentric bloated tight sleeve are not concentric with the external diameter, and this makes eccentric bloated tight sleeve 6's outer wall thickness uneven to eccentric bloated tight sleeve 6 surface processing has the annular knurl, thereby increases frictional force. The cross section of the lower fixing pin 3 of the bearing inner rail is semicircular, the bottom of the lower fixing pin is a plane, the contact part of the lower fixing pin and the bearing inner rail is two points, and the lower fixing pin and the upper fixing pin are matched to form three points for fixing a circle, namely the bearing inner rail. The bottom of the vertical plate is connected with two eccentric cylinders 4 through rotating shafts respectively, the eccentric cylinders 4 are located on the same side of the lower rail fixing pin 3 in the bearing, the centers of the two eccentric cylinders 4 are aligned with the center of the lower rail fixing pin 3 in the bearing, and the rotating shafts on the rear sides of the two eccentric cylinders 4 are connected with synchronizing gears 5 which are meshed with each other. The eccentric cylinder 4 and the synchronous gear 5 are fixed on the rotating shaft through keys and can rotate along with the rotating shaft.
When measuring the bearing play, put the bearing of awaiting measuring on a pair of eccentric cylinder 4 upper portions earlier, with the eccentric tight sleeve 6 cover of expanding on the fixed pin 2 on the bearing inner rail, make the eccentric tight sleeve 6 thin wall department of expanding lie in upper portion, the spacing of fixed pin 2 and bearing inner rail lower fixed pin 3 on the adjustment bearing inner rail is fixed the bearing inner rail, then screw eccentric tight sleeve 6 that expands and firmly fasten the inner rail. One of the eccentric cylinders 4 is rotated, the support of the bearing is loosened, the bearing outer rail is in a suspended sagging state, the dial indicator is adjusted to enable the pointer to be at a zero position, the eccentric cylinder 4 is rotated again, the two eccentric cylinders synchronously jack up the bearing outer rail through the meshing of the pair of synchronous gears 5, and the value read out by the dial indicator is the maximum value of the movable clearance of the rolling bearing.
In actual operation, if the movable play value of the bearing is not detected if the movable play value exceeds the limit, the equipment can generate faults such as vibration and the like during operation, and the service life of other parts of the equipment can be influenced.
The first embodiment is as follows: in 2017, the motor front end of the 2# outward-conveying pump at a certain station is abnormal in operation sound, the problem of a bearing at the front end of the motor is preliminarily judged, the movable clearance value of the bearing is 0.05 mm detected by the measuring device and exceeds the standard range of use, and the motor-pump operates normally after a new bearing is replaced.
Case two: in 2018, the rear end bearing part of the station No. 1 water mixing pump runs violently shakes, the preliminary judgment is that the bearing movable clearance value is too large, the bearing is measured by the measuring device after being detached, the movable clearance value of the bearing is accurately obtained to be 0.02 mm, in a normal standard application range, the reason that the shaking is caused is found through further careful inspection, the problem occurs to other parts instead of the bearing, and the waste caused by one-time blind replacement of a new bearing is avoided.
